US IRA: Roth vs Traditional Explained (2026 Limits & Income Rules)

US IRA: Roth vs Traditional Explained (2026 Limits & Income Rules)

In US retirement planning, the IRA (Individual Retirement Account) is the other main pillar alongside the 401(k). It's a retirement account you open yourself, not through an employer — and the eternal question is “Roth or Traditional?” It comes down to saving on taxes now or withdrawing tax-free later. Every figure below comes from the IRS's confirmed 2026 amounts.

1. What you can put in. $7,500 for 2026, or $8,600 at 50 and over (a $1,100 catch-up) — up from $7,000 in 2025.
2. Where the risk is. That limit is shared between Traditional and Roth. Split across both and the combined total still cannot exceed $7,500 ($8,600 at 50+) — treating them as separate buckets creates an excess contribution.
3. What to do. One thing few people know: if only one spouse is covered by a workplace retirement plan, the uncovered spouse gets a much higher income range — $242,000 to $252,000 per the IRS, separate from the $129,000 to $149,000 band that applies when the contributor is covered. Check that band before concluding “we earn too much.”

What is an IRA?

An IRA is a retirement account you open yourself at a bank or brokerage, choosing your own investments. Use it when you have no employer 401(k), or after maxing one out. The two main types are Traditional and Roth.

2026 limits — the IRS figures

Item20262025
Base contribution$7,500$7,000
Catch-up, age 50++$1,100 (total $8,600)+$1,000
Applies toTraditional + Roth combinedSame

Note — this limit is combined across Traditional and Roth. Split between them if you like, but the total can't exceed $7,500 ($8,600 at 50+). It's separate from the 401(k) limit, so you can add an IRA even after maxing a 401(k).

Over-contributing is not a one-time penalty. The IRS states that excess contributions are “taxed at 6% per year” — and it repeats every year the excess stays in the account. If you spot the mistake, remove it rather than leave it.

On age limits: the 70½ contribution bar was removed for 2020 and later. The IRS page separates “2020 and later” from “2019 and earlier.” With earned income, age no longer stops you.

Traditional vs Roth: the core comparison

Roth's big wins are tax-free retirement income and no RMDs — grow it large, withdraw tax-free, and it's advantageous to leave to heirs.

Roth IRA income limits (2026)

High income restricts direct Roth contributions. The 2026 MAGI ranges from IRS release IR-2025-111:

Filing status2026 phase-out range2025
Single / head of household$153,000 – $168,000$150,000–$165,000
Married filing jointly$242,000 – $252,000$236,000–$246,000
Married filing separately$0 – $10,000Same (not indexed)

Married filing separately runs $0 to $10,000. That is effectively a closed door — and the Traditional deduction band is identical. The IRS notes this range is not subject to a cost-of-living adjustment, so it never rises. If you are weighing separate filing, put this in the calculation. For how much is left while you are inside a band, see the IRA contribution and deduction calculator; for why the figure flattens just below the ceiling, see the $200 floor.

Look at how far each band moved in a year, not where it sits, and one row stands still.

How far the Roth IRA phase-out band moved from 2025 to 2026: three thousand dollars for single filers, six thousand for joint filers, and nothing at all for married filing separately
The joint band rose exactly twice as far as the single one, and the separate band is not indexed, so it never rises (our arithmetic).

Traditional IRA deduction ranges (2026)

With a Traditional IRA, contributing and deducting are separate questions. You can contribute at any income, but being covered by a workplace plan limits the deduction.

Situation2026 phase-out range2025
Single, covered by a workplace plan$81,000 – $91,000$79,000–$89,000
Married filing jointly, contributor covered$129,000 – $149,000$126,000–$146,000
Contributor not covered, spouse covered$242,000 – $252,000$236,000–$246,000
Married filing separately, covered$0 – $10,000Same (not indexed)

Same scheme — but which row you fall into changes how wide the door is.

The third row is the one to notice. If you are self-employed with no workplace plan and only your spouse is covered, the deduction survives all the way to $242,000 of joint income — over $110,000 more headroom than when the contributor is covered. That band is also exactly the joint Roth contribution band — the four widths set side by side are in the traditional IRA deduction bands.

If income shuts you out of a direct Roth contribution, the Backdoor Roth route is to contribute to a Traditional IRA and convert. The basis is that IRS Publication 590-A states conversions have no income limits. Contribution limits and conversion limits are separate axes.

The Saver's Credit — check it if income is modest

Simply contributing to a retirement account can earn an extra credit. The 2026 income ceilings:

Filing status2026 ceiling2025
Married filing jointly$80,500$79,000
Head of household$60,375$59,250
Single / married filing separately$40,250$39,500

Early-career and part-time earners often qualify. Worth checking while you are already opening the account.

Set the three ceilings side by side and the ratio is hard to read as coincidence.

The 2026 Saver's Credit income ceilings of 80,500, 60,375 and 40,250 dollars shown against a unit scale, forming an exact 4 to 3 to 2 ratio
$80,500 / 4 = $20,125, and the other two land exactly on 3x and 2x it — 2025 held the same ratio (our arithmetic).

Example: a 30-something earning $90,000

Single, $90,000 a year, in your 30s. ① Your income is under the Roth limit ($153,000), so you can use a Roth IRA. ② Being young with income likely to rise, paying tax now (Roth) and withdrawing tax-free later tends to win. ③ First capture your 401(k) match, then fill the Roth IRA to $7,500. ④ Feel the long-term compounding with our compound calculator.

What order to save (the classic sequence)

  • ☐ ① 401(k) up to the employer match (free money)
  • ☐ ② Fill the IRA (consider Roth first)
  • ☐ ③ Finish maxing the 401(k)
  • ☐ ④ Beyond that, a taxable brokerage account
  • ☐ Always keep an emergency fund (3–6 months) separate

Key point. Roth vs Traditional is really “pay tax now or later.” Low rate now (early-career/low-income) → Roth; high rate now → Traditional deduction. Unsure? Splitting between them is fine.

Questions you may have

Q. Can I have both a 401(k) and an IRA?

Yes — separate limits. But Traditional IRA deductibility can be limited if you have a workplace plan, based on income. Roth IRA follows the income limits above.

Q. Can I withdraw Roth principal anytime?

Checked against Publication 590-B (2025 returns) on 23 September 2026 — an earlier version left this unverified because the section would not extract.

  • There is a fixed order — “Regular contributions” come out first, then conversion and rollover contributions (first in, first out; the taxable part of each first), and earnings last.
  • The contribution portion is not income — the IRS example says “the first $5,000 of the distribution is a return of Amelia’s regular contribution and isn’t includible in her income.”
  • There are two five-year rules. (1) A tax-free qualified distribution needs five years from the first tax year you contributed to any Roth IRA, plus age 59½, disability, death (to a beneficiary) or a first home (up to $10,000 lifetime). (2) Each conversion has its own five years, counted from the first day of the conversion year; taking it out sooner can bring a 10% additional tax on the part that was taxed at conversion.

So “contributions any time” holds for money you put in directly; converted money withdrawn within five years can be different. The actual computation is Form 8606, Part III.

Q. What does an early withdrawal cost?

Generally a 10% additional tax. But a SIMPLE IRA withdrawn within the first two years carries 25%, not 10% — a difference many people miss.

Q. I over-contributed by mistake.

It is taxed at 6% per year, repeating. Not a one-off — fix it promptly.

Q. I'm over 70 — can I still contribute?

Yes. The 70½ limit was removed for 2020 and later. Earned income is all you need.

Q. What's a Backdoor Roth?

A legal way for high earners to reach a Roth: contribute to a Traditional IRA, then convert. Existing Traditional balances complicate the tax (pro-rata rule), so consult a tax pro.

Q. Does this overlap with Korea's pension?

Different systems, no overlap. Use an IRA on the US side; use Korea's national pension on the Korean side. With both work histories, check the US-Korea totalization agreement.

A traditional IRA requires a minimum withdrawal each year from age 73 — the first deadline and the 25% for missing it are set out from the IRS in US required minimum distributions.

Sources and where to check

Written as of July 2026. Contribution limits, catch-ups, Traditional deduction ranges, Roth income ranges, the Saver's Credit, the 6% excess tax, the removal of the 70½ bar and early-withdrawal rates all come from the IRS sources above, with update dates noted. The Roth five-year rules and ordering rules were left blank at first because Publication 590-B would not extract, and were filled from the original on 23 September 2026 (FAQ above). The Backdoor Roth pro-rata rule is half filled: 590-B says a distribution from a traditional IRA holding nondeductible contributions is split using Form 8606, valuing all traditional IRAs, SEP and SIMPLE included, as of 31 December (except in the year of death) — which is why existing balances get pulled in. We did not check the Form 8606 worksheet line by line. The IRS's dedicated Roth limit page has no 2026 edition (only 2024 and 2023), so the release was used instead. A Backdoor Roth gets complicated when you hold existing Traditional balances — consult a CPA. This is general information, not tax or investment advice.
