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. Here are the 2026 limits, income rules, and how to choose.

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

Item2026 limit
Base contribution (under 50)$7,500
Catch-up, age 50++$1,100 (total $8,600)
Applies toTraditional + Roth combined

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).

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 earners are limited from contributing directly to a Roth. Here are the 2026 MAGI ranges.

Filing statusFull contributionPartial (phase-out)Not allowed
Single / HoHUnder $153,000$153,000–$168,000Over $168,000
Married filing jointlyUnder $242,000$242,000–$252,000Over $252,000

If your income is too high, the Backdoor Roth (contribute to Traditional, then convert) is an option — confirm with a tax pro. Traditional IRA deductibility may be limited by your income and whether you have a workplace plan.

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.

FAQ

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?

Your contributions can be withdrawn anytime, tax- and penalty-free (earnings have conditions). That flexibility is a Roth plus — though it's best left to grow.

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.

An IRA boils down to "Roth or Traditional = pay tax now or later." Roth when young and low-rate, Traditional when income and rates are high — and fill it right after the 401(k) match.
