Korea's Floor-Noise Limit Is 39 dB - One Thud Does Not Break It
Every number in Korea's floor-noise standard sits in one table. And a note under that table says the peak limit is only exceeded when it is passed three or more times in an hour.
Drunk Driving in Korea - Refusing the Test Costs More Than Failing It
What happens if you refuse the breath test? Art. 148-2(2) of the Road Traffic Act puts it at one to five years - heavier than blowing under 0.08%, and the licence is revoked with no discretion left.
Should You Go to the ER Over a Holiday? Korea Writes the List Into the Rule
What counts as an emergency symptom is set out under nine headings in Table 1 of Korea's Emergency Medical Service Rule - and one entry has the word "holiday" inside it: a child's fever over 38C.
When a Parcel Arrives Broken - Taking It "Without Reservation" Ends the Claim
Art. 146 of Korea's Commercial Act extinguishes the carrier's liability once you receive the goods without reservation and pay the fee. Damage you could not see gets two weeks - and a valuable is not covered at all unless you declared it.
Korea's Overtime Limit Checker - The 52-Hour Week Is the Ordinary-Hours Figure
52 is art. 50's 40 plus art. 53's 12, and that 40 is the ordinary-hours figure - under a flexible scheme it becomes 48 or 52, so a single week may lawfully reach 64. Enter the scheme and the worker to see this week's ceiling.
Korea's Habitual Wage Arrears Checker - "Five Times" Means Five Workers
Read art. 43-4's "five or more times" as five late paydays and you have it wrong - the Decree counts the workers who went unpaid. Enter the convictions and the arrears to see which of the four routes attach.
Korea's Unpaid Wage Interest Calculator - 20% a Year, and Three Times in Court
Fourteen days after you leave, and from the next day interest runs at 20% a year. Since 23 October 2025 it runs on wages unpaid while you are still employed, and any one of three grounds lets you claim up to three times in court.
Korea's Holiday Substitution Checker - The Weekly Rest Day Has No Substitution Clause
"Work the holiday, rest next week instead" - the basis is one proviso in art. 55(2), and it is attached to public holidays only. Enter the kind of holiday and the kind of agreement to see whether the substitution stands and what the premium comes to.
Korea's Unpaid Retention Subsidy Calculator - This Money Goes to the Worker's Account
Same name, different pocket: the paid retention subsidy goes to the employer, the unpaid one straight to the worker. A 20-person workplace needs half its staff off for 30 days; a 99-person one needs ten - and both numbers are ten.
Korea's Employment Retention Subsidy Calculator - A Large Firm Gets Two-Thirds Too, Past a Half-Cut
The state returns two-thirds of the shutdown allowance the employer paid - one-half at a large firm. But cut more than half the month's contract hours and a large firm gets two-thirds as well, because item (ii) of the provision carries no large-firm bracket.
Korea's Annual-Leave Substitution Checker - Since 2022 a Public Holiday Is Not a "Working Day"
"Use your annual leave on the public holiday" - art. 62 allows substitution only on a specific working day, by written agreement with the workers' representative, and since 2022 public holidays are paid holidays at every workplace with five or more workers. Enter the kind of day and the kind of agreement to see whether it stands and how much leave is left.
Korea's Shutdown Allowance Calculator - The Floor Is 70% of the Ordinary Wage, the Ceiling 100%
The statute says "70% of the average wage", but for a monthly-paid worker without bonuses it becomes 70% of the ordinary wage, because art. 2(2) lifts the average to it. Enter the shutdown date and three months' pay for the legal minimum; anything received comes off before the 70%.
Korea's Maternity Leave Benefit Calculator - Firm Size Changes Who Pays, Not What You Get
On a 3m won monthly wage a priority-support firm's worker gets 6.6m from the state and 1.6m from the employer; at a large firm it is 2.2m and 6m - the same 8.2m won either way. Enter your wage and firm size to see the split.
Korea's Annual-Leave Use-Promotion Deadline Calculator - Ten Days from 1 July, Then 31 October
Whether the employer's notice fell inside the "10 days from six months before" window turns on a single date. Enter your hire date for the window and both deadlines; under one year of service there are two clocks.
Korea's Severance Interim-Settlement Checker - The Only Route That Runs Before Your Pay Falls
Of the nine settlement reasons, three - a wage-peak scheme and two kinds of hours cut - appear in neither the collateral list nor the DC withdrawal list. And even a listed reason leaves the employer with "may".
Korea's Separation Code Checker - Between Codes 11 and 12 Sits Table 2
The leaving confirmation has nine codes, and they live on the back of a statutory form, not outside the law. Code 11 goes to art. 58(2), code 12 points at Table 2, and 26 is not a bar by itself.
Korea's Unemployment Benefit for the Self-Employed - Only Two Things Are Left Out
The base amount comes not from your takings but from the figure you insured on. And one missed premium is enough to block it if you have only just passed a year.
Korea's EITC Half-Year Claim - the Months-Worked Divisor Moves More Than the 35%
Annualising first-half income multiplies it by seven at one month worked and by two at six. Fewer months means a larger deemed income - unless you left mid-year, when it is fixed at six months.
Korean Unemployment Benefit for Artists and Contract Workers - the Thirteen Just Causes
The list has thirteen items, the same as for employees - but it carries one figure the employee list does not: a change of 20 per cent or more to the contract terms. And what the borrowing list leaves out matters more.
Korea's Other Unemployment Allowances - 10,320 Won a Day, 25 Kilometres and 7.5 Tonnes
Three more payments sit beside the jobseeker's benefit. None of them carries its amount in the Act, and two are sent to a table in the civil-service travel rules - which turns out to have no distance in it.
Can You Claim Korean Unemployment Benefit After Resigning - the Thirteen Just Causes
The Act lists what disqualifies, not what qualifies. The exceptions are the thirteen items of Table 2, and only four of them carry a figure: two months, three hours, 30 days, age 8.
Korea's Youth Housing Subscription Account - One Account, Two Clocks
The interest exemption and the deduction are separate schemes. They read different years (last vs this), and claw back over different windows (two years vs five). Subtract military service and 40 still counts as young.
Korea's Housing Subscription Deduction - a 1.2m Won Deduction Hands You 198,000 Won
40% of up to 3 million won a year comes off your income, not your tax, so only your rate returns. And closing within five years repays 2.27 times what the 6% band ever saved.
Korea's Early Reemployment Allowance - Nothing at 104 Days, 3.47m Won at 105
It pays half of the jobseeker benefit you leave behind. But you must leave at least half, start more than 14 days after filing, and earn under 5.74m won a month at the new job.
Korea's 2027 Minimum Wage Checker - 10,700 Won, and Why the Same Pay Is 9,743 If Meals Are in Kind
Up 380 won (3.7%) to 2,236,300 a month. But the pay measured against it is not the total - it is regular monthly pay, and bonuses and meal money have counted in full since 2024.
Korea's Regional Health Insurance Premium Calculator - the Same 24m Won Costs 71,900 as a Pension and 143,800 as Business
One line for income, one for property. Only wages and pensions count by half, and property is nothing to 100m, then 4,653 won from the next 10,000.
Korea's Health Insurance Dependant Test - Interest Counts as Zero to 10m Won, and in Full One Won Over
There is more text between "income 20m" and "property 540m". Pensions count in full, financial income is a cliff, and past the property line the income limit halves.
Basic Pension Income Test - the Same 100m Won Can Be Nothing, 267,000 or 100m
A home under the allowance is zero, savings convert at 4 percent over 12 months, and a car counts whole every month. That is the order of the words in the Rule.
Deductions Korea's Tax Feed Leaves Out - and Why
It was the Decree, not the tax office, that removed glasses and hearing aids. One proviso explains it.
Korean City Gas Bill Calculator - Heat Units and Discounts
A heat value sits between the volume and the charge, so the same cubic metres cost differently each month.
Korean Energy Voucher Calculator - Eligibility and Amount
The bracket is not the summer share; it is all that remains once winter comes from elsewhere.
Korean Housing Fund Deduction Calculator - One Shared Cap
Rent loan and savings share 4m won, and both sit inside the mortgage interest cap.
Korean National Health Screening - Who Is Eligible This Year
Age is the year minus your birth year, not your age in full years. And only non-desk staff go annually.
Korean Medical Expense Tax Credit Calculator - The 3% Floor
The 7m won cap sits on paragraph 1 only. Whose return a parent's bills go on is decided right there.
Korean Year-End Tax Settlement Calculator - Refund or Bill
The rates do not apply to gross pay. Two subtractions come first. And the child credit now starts at 13.
Korean Interim Income Tax Calculator - Not Half of Last May
The statute adds last November's interim payment too, then halves the sum. Under 500,000 won nothing is collected.
Korean VAT Calculator - Simplified VAT Does Not Subtract Input Tax
It multiplies sales by a sector rate instead, so however large the purchases, no refund arrives.
Korea's Monthly Rent Tax Credit Calculator - Four Thresholds, and Rent Counted by Days
In February 2026 the way the rent itself is counted changed - days rented, not months paid.
Korean Inheritance Tax Calculator - The Deductions Come Before the Rate
With a spouse and children, nothing is due up to 1bn won - that is what the statute says.
Korea's Pension Savings and IRP Tax Credit Calculator - Two Caps, and You Need Tax to Owe
The same 9m won lands differently by where it went, and short of tax the rest simply disappears.
Korea's ISA Tax-Saving Calculator - The Tax Is Not on the Profit
Only interest and dividends after losses and fees are taxed - this puts a number on the difference.
Korea's ISA Loss Set-Off - There Is an Order, and Fees Come Off Too
Gains on listed Korean shares are not taxed, yet the losses are allowed into the set-off.
A Korean ISA Is Not Locked for Three Years - Withdrawals Come Out of Principal
Take out anything up to what you paid in and nothing happens - the Decree orders it that way.
Korea's Child Credit Calculator - Per Child, and How It Compares With the Child Tax Credit
The table figure is per child, so the count multiplies straight through - and the end is a cliff.
Korea's EITC Household Types - Both Spouses Working Is Not the Test
The statute asks for 3m won from each — a spouse who earned 2.5m leaves you a one-earner household.
Korea's EITC: the Statutory Formula and the Amount Paid Are Different Numbers
The table prices each band at its favourable end and rounds up — so it always pays more than the formula.
Korea's Earned Income Tax Credit Calculator — What the Table Pays, Not the Formula
Working the statutory formula under-reports the benefit; the amount comes from the Decree's benefit table.
Age and Holding Relief — the Tables Add to 90%, the Law Cuts at 80%
Age 65 with 15 years and age 70 with 10 land on exactly the same figure — and nothing beyond it.
Two Rate Tables — Korea's Three-House Heavy Rate Really Starts at KRW 2.9bn
The tables are identical up to a base of 1.2bn — below that line, the number of houses changes nothing.
Comprehensive Real Estate Tax Calculator — Six Steps from the Published Price
Deduction off, 60% applied, property tax given back — the notice built in the order the statute builds it.
Spending an HSA on Something Other Than Medical Care — the 20% and Age 65
At 65 the 20% goes away but the income tax does not — it is not free from there on.
The Dependent Care FSA — the 2026 Limit Is $7,500
Same name as the other FSA, 2.2 times the size — and the lower earner's income is the ceiling.
IRA Contribution and Deduction Calculator — What Is Left Inside the Band
Halfway through the band you get exactly half the limit — and the IRS worksheet carries two lines the short page does not.
The Last $400 of the Roth IRA Band — the Cliff the $200 Floor Creates
One dollar of income costs $200 — and two IRS pages give different answers.
The Traditional IRA Deduction Bands — Same Rule, Widths Reversed
A single filer loses the deduction first and fast; a joint filer loses the contribution first.
Social Security Claiming-Age Calculator — 62 vs 67 vs 70, and Where They Cross
The early reduction is not one rate — the three years before full retirement age cost 6.67pp each, and everything earlier costs 5.0pp.
The 78-83 Social Security Break-Even — Re-Run, It Is Three Numbers
“Around 78 to 83” was never a range. Name the comparison and it lands on 78y8m, 80y4m or 82y6m.
Social Security Withheld for Working — It Comes Back at Full Retirement Age
Withheld months are erased from the reduction count. Claim at 62 with an FRA of 67 and the benefit climbs from 70% to 75% to 80%.
Korea's Long-Term Holding Deduction — Residence Alone Is Worth KRW 11.6m
Two people sell the same home after the same ten years. One pays 2.62m, the other 14.23m. Holding is not what separates them.
Korea's KRW 1.2bn Apportionment — A Slope, Not a Cliff
“Exempt up to 1.2bn” is right. The sentence that usually follows is not — crossing it does not put the whole gain into tax.
Korean Capital Gains Tax Calculator — Apportionment and Both Deduction Tables
Sell above KRW 1.2bn as a one-home household and a sixth step appears — apportionment. It is why crossing the line does not mean a big bill.
Korea's 600m to 900m Acquisition Tax Slope — KRW 10m Costs 923,000
“1 to 3%” is right on average. Measure what another KRW 10m of price costs in tax and a different number appears.
The Rural Surtax and the 85 Square Metre Line
Cross 85 square metres of exclusive area and the notice gains a line. On a KRW 900m home that is 1.8m won; under the 12% heavy rate, 9m.
Korean Acquisition Tax Calculator — With Both Surtaxes
The notice carries more than one tax. And between KRW 600m and 900m the rate is not in any table — it comes out of a formula.
One Korean Gift Tax Return Is Worth KRW 25 Million
File on time and 3% comes off; fail to file and 20% goes on — twenty-three percentage points on the same tax.
Korea’s Ten-Year Gift Rule — Aggregation Splits, the Deduction Merges
“Ten years” appears twice in the gift tax. Same number, opposite ways of counting people — which is where most of the confusion lives.
Korean Gift Tax Calculator — Statute Order, Deduction to Filing Credit
It gets remembered as “fifty million won is fine.” What decides the bill is who gave it to you, and whether they gave you anything in the last ten years.
Counting Dependents for Korea’s Subscription Score
Thirty-five of the 84 points sit here, at five points a person. But the term does not mean what the everyday word means, and counting the people you live with will be wrong.
Where Korea’s No-Home Period Splits — The Start Date Is Settled Twice
Fifteen years of renting from age 20 counts as zero if the start date has not arrived. The errors come not from adding wrong but from picking the wrong date.
Korea Subscription Score Calculator — 84 Points in Three Parts
32 points for years without a home, 35 for dependents, 17 for the account. The arithmetic is not the hard part — which day the count starts, and who counts, are.
What Unused Annual Leave Is Worth in Korea — Ordinary Wage and the 209 Hours
“Unused leave gets paid out” is half true. The statute's default is that it lapses and payment is the exception — and the number you divide by, 209, appears in no statute at all.
Leaving After Exactly One Year in Korea — When One Day Decides Fifteen
You counted on “a year worked, so fifteen days” and eleven arrived. It is not an error: finish exactly one year and the fifteen days never come into existence.
Korean Annual Leave Calculator — 11 Days at One Year, 26 One Day Later
Enter a hire date and a reference date and you get both the days accrued and what the unused ones are worth. The sharpest split is leaving after exactly one year: 11 days against 26, decided by a single day.
Cancelling a Chuseok Train Ticket — Free on a Weekday, 20% Over the Holiday
KORAIL's penalty table has two rows. Monday to Thursday is free until three hours before departure; Friday to Sunday and holidays carry a minimum penalty even a month out. On a 100,000 won fare that is 5,000 against 20,000.
Chuseok Groceries — We Counted 74 Items, and 54 of Them Fell
The median retail item is down 7.2% on a year ago. Yet Singo pear is +24.9% and Tsugaru apple is −29.1% — 54 points apart inside the same category. It is not an average, it is a split.
Korean Gift With Assumed Debt — Between Family, the Default Runs the Other Way
The Act subtracts assumed debt, and the Decree names the rental deposit as one. One paragraph later it presumes that between spouses and lineal relatives the debt was never assumed.
Korea's 20m Won Financial Income Threshold — Crossing It Can Cost Nothing
Twenty million is not the line where the rate changes but where the method does. The statute runs two calculations and keeps the larger — and with no other income the withholding side wins up to 77.61m won.
Korean Retirement Pension Early Withdrawal — Enough to Pledge, Not Enough to Withdraw
The grounds are a closed list in the Enforcement Decree. But the pledge list and the withdrawal list differ, and university fees, weddings and funerals appear only on the first.
Korean Severance Tax Calculator — The Same 100m Won, Taxed 39 Ways
How much you received is only half of it. The statute divides the payout by years of service, runs it through the rate table, then multiplies it back — so longer service drops it into lower brackets.
Chuseok Safety — 1,474 Bee Stings, and 12,038 Road Injuries in the Same Tables
Korean holiday notices lead with bees and snakes. The same fire service tables carry a number eight times larger — and because the holiday runs 4 to 6 days, the yearly totals do not compare.
Chuseok Expressway Toll Exemption — Four Holiday Days, Three Toll-Free
Behind the one-line claim that tolls are waived again sit three separate conditions. One of them leaves the last day of the holiday out.
Only One Renewal in Three Used Korea's Statutory Renewal Right — We Counted 7,719 Filings
The statute cannot tell you how often the right is used. The rental filing data can, because it carries the answer as a field.
Seoul's Policy Loans Cost 2.65% After the Subsidy — and the Subsidy Is Where Banks Differ
A policy loan brochure quotes two rates: what the bank charges and what the city pays. The borrower carries the gap, which nothing publishes.
Jeonse Loan Rates Differ by 1.99 Points Between Banks — With the Same Guarantee Behind Them
The lowest was 3.79% and the highest 5.78%. On a KRW 100 million loan that is KRW 1.99 million a year.
Korean DSR Calculator — the Ratio That Sets Your Limit, Not You
Enter income and existing debt to see how much more you can borrow, and what the limit would be with the stress rate switched off.
Korea's 40% DSR Is Not in the Statute — the Three Documents That Set It
The Banking Act carries no figure, the regulation pushes it into a table, and the arithmetic is delegated again to the supervisor.
Five Places People Get Korea's DSR Wrong — All of Them in Figures
Counting interest only gets you a quarter of the way, the heavy thing is the term rather than the balance, and the LTV limit is not your limit.
Korea's Housing Subscription Deposit Goes by Where You Live, Not Where You're Buying
The note under table 2 pins the threshold to your resident registration area. And you may pay 500,000 won a month while only 250,000 is ever counted.
Korea's National Health Screening — There Is No “Odd or Even Birth Year” in the Law
The decree fixes an interval of once every two years, nothing more. Birth-year parity is how that two-year cycle is run, not a legal requirement.
The First Gate Before a Korean Small-Business Policy Loan — Counting Staff Has Its Own Rules
A part-timer at 60 or more hours a month counts as half a person, and the measure is last year's month-end average rather than how many work here today.
The Order to Check Before Buying a Home in Korea — The Reversible Stretch Ends at “Beginning Performance”
Money leaves as deposit, interim and balance, but the point of no return and the point of ownership arrive somewhere else. The order comes from the statutes.
What Korea's Fine Dust “Bad” Actually Means — Two Different Rulers
The top of the PM2.5 “Moderate” band, 35 micrograms, is the legal 24-hour standard itself. “Moderate” is not safe; it means today's limit has not been passed yet.
Korean Holiday Work Pay Calculator — Chuseok 2026, and Why Headcount Comes First
The 1.5x answer is right but incomplete. Table 1 of the Enforcement Decree omits article 56 from the Chapter 4 cell, so below five staff the premium is not 1.5x but zero.
Korean Card Deduction Calculator (2026) — Start With How Far to the Threshold
The card deduction closes on 31 December, so checking it in January changes nothing. This calculator answers one question instead: have you cleared the threshold, and if not, how much is left?
Flu Vaccination in Korea — Who Pays Nothing, and What “by the End of October” Means
The state covers three groups, and no more. And “by the end of October” is measured from when antibodies appear, which makes 17 October the cut-off for a single dose.
Korea's 2026 Tax Reform Bill — From Holding to Living There, and It Is Still a Bill
Almost every write-up says “here is what changes from 2027.” But this goes to the National Assembly on 3 September. One axis runs through all of it — not how long you held the home, but how long you lived in it.
2.73 Million Cancer Survivors in Korea — What ‘One in 19’ Means (2026)
62% of that number were diagnosed more than five years ago. It counts 25 years including people who were cured, and over half are 65 or older.
Bone Density Testing — When to Go, and How to Read T and Z on the Report
Korea's programme covers women at 54, 60 and 66. Before menopause the report gives a Z-score rather than a T-score, so read the letter before the number.
Anaemia Testing — The Health Check Measures One Thing (2026)
Ferritin, which shows stored iron, is not a national screening item. There is a stretch where the stores drain while the blood still holds — and the report prints ‘normal’.
Korea Housing Market 2026 — Supply Cliff, Jeonse Squeeze, Stress DSR
Supply cliff, jeonse squeeze, tight lending. Check your loan limit before timing the market.
Korean Inheritance Tax — Facts, Not Headlines (2026)
“A 20% financial-asset deduction” only holds between ₩100M and ₩1B — the provision actually has four bands.
Jeonse to Monthly Rent Calculator — The 4.75% Cap Comes From Two Clauses (2026)
Enter deposits and a rate for the fair monthly rent — plus where “the lower of base rate plus two and ten percent” actually comes from.
Korean Capital Gains Tax A to Z — Rates, Deductions, Expenses (2026)
From 10 May 2026 the multi-home surcharge is back: +20 points for two homes in adjusted areas, +30 for three or more, and no long-term holding deduction.
Korean Acquisition Tax Explained — Why It Ranges From 1% to 12%
Local education tax is not a share of the acquisition tax: the provision says “(rate − 2%) × 20%,” and homes use a different formula entirely.
Korea's Comprehensive Real Estate Tax vs. Property Tax — Why December Bills Too
1.2B won for one home, 900M for others. Because it's totalled per person nationwide, the same value gives different results.
What Health Insurance Costs After You Retire — and Three Deadlines You Can't Undo
Voluntary continuation is exactly double what you paid while employed (325,392 won a month on a 4m salary). The comparison that counts is against regional enrolment.
Fixed or Variable — One Point Is About 60,000 Won a Month per 100 Million
Don't choose on a forecast. You can answer whether you could pay two points higher — and that answer is about 120,000 won a month per 100 million.
Korea's ISA — How Much Tax It Saves, How to Open One, and What Changes in 2027
On a 6 million won gain an ordinary account is taxed 924,000 won; a low-income ISA, 198,000. The savings in figures, whether the principal is protected, how to open one, and the 2027 reform bill.
When the Internet Is Down — 30 Seconds Tells You Whose Problem It Is
Put another device on the same Wi-Fi. That one check decides a 15,000-won callout fee — while compensation for two hours is 917 won.
When the Computer Slows Down — Money Enters at Exactly One Point
The first six steps cost nothing. Task Manager tells you whether to spend — memory high always means RAM, the disk at 100% constantly means an SSD.
How Much Water a Day — The Two Litres Is Total Water, Food Included
The liquid you actually drink is 1,000-1,200 mL for men and 900-1,000 for women. And there is a ceiling — 1.4 litres an hour.
When the Computer Shuts Off — Whether It Slowed Down First Decides the Cause
Heat cuts speed before it cuts power. A shutdown with no slowdown is probably not thermal — and that one fact changes both the document and the bill.
Blank Screen or No Sound — Three Seconds Decides the Bill
Press Windows + Ctrl + Shift + B; a beep means the PC is on and only the display is out. That result is what splits free from paid.
When the Computer Won't Turn On — Five Minutes Decides Free or Paid
Cable, 15 minutes of charging and a long press cost nothing. What splits the bill after that is adapter versus logic board — and the board is covered for two years.
Should You Eat Breakfast? No Link for Adult Weight, a Link for Children
No firm evidence says an adult's weight turns on breakfast. What does change is diet quality — three meals score about 5 HEI points higher than two.
Caring for Someone with Cancer — What Happens to the Carer, and What Support Exists
A national agency guide carries the heading ‘be prepared that some people may not help.’ And in Korea there is an expense programme applied for at a health centre.
Ten Thousand Steps — The Guidance Is Written in 150 Minutes, Not Steps
You can hit ten thousand steps with intensity and strength still empty. Moderate means you can talk but not sing — walking, that's 2.5 mph or faster.
Common Cancer Myths — Where the Worry Goes Isn't Where the Weight Is
Only 5-10% of cancers are inherited. The weight sits on smoking at 30%, diet at 30% and chronic infection at 10-25%.
How Much Sleep Do You Need? Seven Is the Floor — And Filling It Isn't the Whole Answer
The CDC adult row reads “7 or more hours.” Koreans sleep 7h 45m on weekdays — 45 minutes above that floor.
Korea's Jobseeker Benefit - a 68,100 Won Cap, a 66,048 Won Floor, and Days That Expire After a Year
Only 2,052 won separates the cap from the floor, so doubling the salary barely moves the daily figure. And the year runs from your last working day, not from the day you apply.
Thyroid Cancer in Korea — How Common, How Dangerous, and Should You Be Screened (2026)
35,440 diagnoses in a year, about one person in 1,443. What a 100.2% survival rate actually means, and why it is not in the national screening programme.
Home Emergencies: What to Do (and What Never to Do)
Burns, bleeding, sprains — plus the quietest danger at home, and one CDC figure that does not add up.
CPR and Choking Response: 6 Steps That Save Your Family
Survival was 14.4% when a bystander acted and 6.1% when none did. And the agency page opened this time, so we could read what the survey counts.
The Home First-Aid Kit — Convenience-Store Medicine Is the Exception, Not the Rule
Counting the agency's own kit list gives 26 items. And the Act itself explains why the convenience-store selection can never exceed twenty.
Reading Korea's Property Register — Sections A and B Are Not Compared by Rank Number
Within a section, rank number. Across sections, receipt number. Article 4(2) is the most misread provision in Korean conveyancing.
Korean Broker Fees — the Rule Says “Determined by Mutual Agreement”
The rates are ceilings, not list prices. And taking more than the ceiling is not an administrative fine but a criminal offence.
Jeonse vs Monthly Rent — the Numbers the Law Actually Fixes
The conversion cap is the lower of 10% a year and the base rate plus 2 points. At a 2.75% base rate in August 2026, that is 4.75%.
Your July Property Tax Bill in Korea — the Numbers Are in the Decree, Not the Act
All the Act contains is a 40-80% band. And the tax burden cap for housing was deleted outright in 2023.
Korea's Gift Tax Deductions — Marriage and Childbirth Together Are Still 100m Won
Paragraphs (1) and (2) each say “separately, 100m won,” which reads as 200m. Paragraph (3) then caps the sum at 100m.
Korea's One-Home Capital Gains Exemption — “How Many Years” Has No Single Answer
Trading up gives you three years; caring for a parent and marriage give ten. And trading up carries a second requirement almost nobody mentions.
Heart Attack Warning Signs — One in Five Sends No Signal
94.9% of U.S. adults know to call 9-1-1. Exactly 50.2% can name all five symptoms.
Korea's Jeonse Contract Checklist — the Order Comes From the Statute
Delivery and resident registration create opposing power; a fixed-date stamp adds priority repayment. And the statute says you cannot be repaid unless you hand the property over.
Splitting Your Accounts — The Law Only Fixes Two Things
Korea's deposit protection cap is ₩100 million, not ₩50 million (amended 29 Jul 2025). And “15.4%” is not a figure in the statute.
Korean Card Points — We Could Not Find “Five Years” in Any Statute
No provision sets an expiry. What the law does set are limits on the terms: unfair clauses are void, and clauses never explained cannot be relied on.
Unclaimed Insurance Money — the Three Years, and the Provision That Protects Them
Commercial Act article 662 fixes an insurance claim at three years, and article 663 stops the policy terms from cutting that down.
Unclaimed Money in Korea — Where “But I Got a Notice” Does Not Help
For taxes the statute says the period is not interrupted by a notice urging you to claim. For health insurance and the pension, a claim does interrupt it.
Korean Residence Records — “Only You” Applies to the Online Service, Not the Counter
The provision opens with “the person or a member of the household” and its proviso spells out delegation. The counter is far wider than the app.
Korea's Medical and Education Tax Credits — What That Parenthesis Releases, and What It Doesn't
The medical credit is not one rate but three, fertility treatment is 30%, and the two age tests are measured from opposite ends of the year.
Magnesium Supplements — The Upper Limit Sits Below the Recommendation
RDA 420 mg, UL 350 mg. Not a typo — the two numbers count different things. And a blood test tells you less than you would think.
Unit Converter — and Why Traditional Korean Units Cannot Appear in Ads
Length, mass, volume, temperature, speed, area and data in one place. And Article 6 of the Measures Act bans non-legal units in trade and advertising.
“Carbon Monoxide Alarms Are Mandatory”? The Notice Says “May Install”
We opened Korea's fire agency notice. Article 4 says “shall install”; the very next article says “may install.” And homes are not on the covered list.
Emergency Fund — One Month First, and Where It Is Actually Safe (2026)
No agency source for ‘three to six months’ turned up, and the line a US regulator drew was one month. Meanwhile the same ‘CMA’ sits in both the protected and unprotected column.
Avoiding Jeonse Fraud 2026 — Register, Fixed Date, Deposit Guarantee
We opened the Housing Lease Protection Act: “0:00 the day after” is nowhere in it, and the test is delivery of the house plus resident registration — both.
Korea Parental Leave Benefit Calculator (2026)
We could never find “the deferred payment was abolished” on Employment 24. Article 95 of the Decree settles it: “(4) Deleted <24 December 2024>.” Nothing in the current legislation provides a basis for it.
Korea's Parental Leave Benefit — 23.1m Won for a Year, How to Claim It, and Your Protections
Past an ordinary wage of 2.5m won the total lands at 23.1m either way. Dismissal is barred by statute, service keeps accruing, and claims open one month in.
Korea's 6+6 Dual-Parent Leave — Not a Doubling, a Rising Ceiling
The provision never says “months used in common.” The ceiling turns on how many months each parent used, and a parenthesis states outright that the periods need not overlap. It also applies during pregnancy.
Pay Down the Loan or Keep the Deposit — 4.74m Won Over Five Years (2026)
A deposit rate above your loan rate still loses after tax. Breaking even needs 1.182 times the loan rate, and no such pairing exists in today's market.
Korea's Tax Calendar — What's Due in Every Month
Comprehensive real estate tax runs 1-15 December; property tax takes land in September, buildings in July, and splits only housing. Under ₩200,000 it is settled in July alone — and the car tax prepayment ceiling is 10%, not 5%.
Semi-Jeonse — How to Split Between Deposit and Rent
Reading the Decree in the Korean original turned up three restrictions the usual table omits. Chief among them: where one building holds several small-deposit tenants, the priority amount is divided proportionally — a common shape in semi-jeonse.
Korea's Conversion Rate Cap and How to Negotiate It
We opened the conversion-rate ceiling in the statute: neither 10% nor 2% is in the Act. Both sit in the Decree, so both can move without the National Assembly — and they already have, twice.
Tenant Rights in Korea — Opposing Power, Priority Repayment, Renewal
In Seoul, deposits up to ₩165m get small-deposit priority and ₩55m is repaid ahead of the mortgage — two different numbers. Renewal is due two months before expiry.
Rent Turns on 1.2 Billion, Jeonse on 300 Million — Two Different Provisions
For a two-home owner the jeonse threshold is ₩1.2 billion, not ₩300 million. The Act sets only a floor and delegates the figure; the Decree puts it at ₩1.2 billion — a provision inserted only last year.
How to Choose a Korea-Listed ETF — Fees, Price Gaps, Fund Size
By law an ETF must permit redemption — which is why divergence cannot widen indefinitely. It may also hold up to 30% in a single security, which sits awkwardly with “an ETF means diversification.”
US-Listed ETFs vs. Korea-Listed Foreign ETFs — Tax Decides
The ₩2.5m allowance for overseas shares comes from Article 103, not the foreign-asset provisions. One allowance across all “shares etc.”, separate from property — and unused, it simply lapses.
Korean ETF Tax — 0 to 1.65m Won on a 10m Won Gain, by Type (2026)
Not every Korea-listed ETF is exempt. Bond and commodity ETFs are taxed 15.4% as ‘other assets’, and the crossover against foreign-listed funds sits at 8.33m won.
Time Deposit or Installment — and the Trap in “Best Rate” (2026)
We worked out the exact multiple behind “an installment plan pays about half the headline rate”: an n-month plan yields (n+1)÷2n — 13/24, or 54.17%, over twelve months, converging on 50% as the term lengthens.
Deposit Protection at ₩100m — The Principal That Fits Is Not ₩100m
The cap covers principal and interest together, so at 3.5% the ceiling is ₩96.62 million. The higher the rate, the less principal fits.
Korean Part-Time Pay Calculator (2026) — The ₩41,280 Step at 15 Hours
The statute measures the 15-hour holiday-pay line as a four-week average, and the probation cut is not “up to 10% of pay” but “the hourly minimum wage minus 10 per cent” — a floor of ₩9,288 in 2026.
Korean Net Salary Calculator (2026) — 9.72% for Most, 6.53% at the Top
The ₩200,000 tax-free meal allowance carries a proviso: “limited to a person who is not provided with meals.” Childbirth support, meanwhile, is tax-free in full with no cap, and childcare allowance runs ₩200,000 per child.
Korea's Annual Paid Leave — 15 Days, a 25-Day Cap, and the Procedure That Cancels Your Payout
Knowing “one year, 15 days” gets you halfway. The statute sets the counting rule, the expiry condition, and the written procedure that lets a company owe you nothing — in three separate places.
Dismissal in Korea — Three Things “I Gave 30 Days' Notice” Does Not Settle
Just cause, written notice and 30 days' notice live in three different provisions. Only the written notice is tied to legal effect; the notice period can be settled with money.
Workplace Harassment in Korea — What the Law Punishes Hardest Is Not the Harassment
The scheme carries exactly one criminal penalty: disadvantaging someone for reporting. Everything else draws an administrative fine, and the definition requires all three of its pieces.
The Menopausal Transition — A Name You Can Only Use a Year Later
NIA and WHO name the same window. The ages, the symptoms, and the finding that waking may trigger the hot flash rather than the reverse.
US HSA vs FSA Explained — Tax-Advantaged Health Accounts (2026)
HSA grows and invests with triple tax-free; FSA is use-it-or-lose-it pre-tax. Plus 2026 limits.
US Credit Scores — Free Reports, 30 vs 45 Days, How Long Marks Stay
One free report a year from each of the three bureaus — and a dispute filed after it gets 45 days, not 30.
US Health Insurance Terms — Four Kinds of Money on Four Different Layers
The deductible marks the start, the out-of-pocket limit the end, and the premium sits outside. Taken verbatim from the Department of Labor's Uniform Glossary.
Find Unclaimed Tax Refunds — A 5-Minute Self-Check (2026)
A notice from the tax office does not stop the five years running — the provision says so in as many words.
Korea VAT Explained 2026 — General vs Simplified, Filing & Refunds
The 104 million won line is not in the Act — VAT Act art.61 sets only a band from 80 million to 130% of it, delegating the figure to the Decree.
Amended Returns — Reclaiming Missed Deductions Within Five Years
We opened Framework Act on National Taxes art.45-2 — and found two three-month clocks running alongside the five years.
Divided and Survivor Pensions — What Happens After Divorce or Loss
The divided pension's five years do not start at divorce — the provision says “from the time all the requirements are satisfied.”
Korea's Monthly Rent Tax Credit — Registration Is the Gateway
We opened Article 95-2 of the Restriction of Special Taxation Act. The 17% band carries a separate ₩45M aggregate-income test, and a clause inserted on 23 December 2025 lets a spouse claim as well — though the ₩10M cap is measured across both.
Making Your Phone Battery Last — Half the Common Advice Is Wrong
We finally checked “a swollen battery is dangerous” against the regulators. The FAA restricts spare batteries to carry-on only, and the CPSC tells consumers to take swollen power banks to hazardous waste, not the bin.
Buying an Apartment in Korea, Step by Step — Contract to Registration
A false transaction report is fined at up to 10% of the price, not a flat sum — on a ₩1B deal that ceiling is ₩100M.
Korean Comprehensive Income Tax Calculator (2026) — Where the 3.3% Refund Turns
The number 3.3% appears in no statute: it is Article 129 of the Income Tax Act (3%) multiplied by Article 103-13 of the Local Tax Act (10% of that tax). The statutory basis for the pension premium deduction is now filled in too.
Korea's Freelance 3.3% — A Number That Appears in No Statute
We opened the provisions themselves. The 3.3% turns out to be 3% x 1.1, and the 8.8% takes three provisions multiplied together.
What's Been Opened in Your Name — Lookup, Block and Alert Are Three Different Services
A ministerial notice defines all three separately. And name theft and name lending lead to opposite outcomes.
The Line an MVNO Has to Beat Is 75% of List Price, Not List Price
One sentence in the official guidance changes the whole comparison: the 25% discount is carrier-only, and MVNO users are excluded.
401(k) vs Roth IRA — 2026 Limits and Income Bands, Read Off the IRS Pages
We opened five IRS pages to pin down the 2026 numbers — and found two of them contradicting each other.
Youth Future Savings (2026) — What the Official Source Actually Says
Korea's Youth Leap Account closed in Dec 2025. We read the two FSC press releases on its successor: three income bands, not two — and no interest rate anywhere.
Get up to ₩1.48M Back Just for Saving: Pension Savings & IRP (2026)
The common line that an IRP needs “six months of treatment plus 12.5% of wages” does not match the text. The 12.5% test belongs to DC plans; the general IRP article carries no such threshold. Articles 2, 14 and 18 of the Decree, side by side.
Side Income in Korea: Must You File in May? The Provision Lists Only Who Need Not
We ran each income combination through Income Tax Act art.73 — including the clause that catches a second job paying wages.

The familiar 10% discount is out of date: the 2026 rate is 5%, and it covers only the months after you pay — September gives 1.25%.
One Degree Costs 7% More Power — But Up to 20.8% More on the Bill (2026)
The Energy Agency's “7% per degree” is about consumption. Run it through the tiers and the bill rises 9.9–20.8%.
Korean Net Pay by Salary, 2026 — You Keep 90% at ₩24M and 79% at ₩100M
Salary rises 4.2 times while net pay rises 3.7. Social insurance is not the cause — income tax is.
