Traditional IRA or Roth IRA
The choice is mostly about when you pay tax. Compare income limits, deductions, withdrawals and required minimum distributions.
The IRA decision is not about which account is better. It is a bet on your future tax rate, and it is the only bet in personal finance where you can move the odds.
If you expect a lower tax rate in retirement than you have now, a traditional IRA wins. If you expect a higher one, a Roth wins. Everything else is detail.
The contribution limit is the small part
Both accounts share one limit: $7,500 for 2026, plus $1,100 in catch-up contributions if you are 50 or older. The deadline for the prior tax year is the April filing date, which means you can still fund last year's IRA for a few months into the new year.
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Contribution, under 50 | $7,500 | $7,500 |
| Tax on the way in | Deductible, unless you have a workplace plan and exceed the income phase-out | After-tax, no deduction |
| Tax on growth | Deferred | Free |
| Tax on withdrawal | Ordinary income | Free, if the account is 5 years old and you are 59½ |
| Income limit for contributions | None, but the deduction phases out | Direct contributions phase out at higher incomes |
| Required distributions | Start at 73 | None during your lifetime |
| Early withdrawals | Prorated, taxed, plus 10% penalty | Contributions come out tax and penalty free at any time |
That last row is the most underrated difference. Roth contributions — not earnings — can be withdrawn whenever you want without tax or penalty, which makes a Roth IRA double as a backup emergency reserve. The traditional IRA has no equivalent, and borrowing against it is not an option.
The forecast is the whole decision
Work out what your marginal rate will be in retirement before you decide, because the answer is not "probably lower" for everyone.
Your rate in retirement is likely to be lower if your income will drop substantially, if you will move to a state without income tax, or if most of your retirement income will come from Roth accounts and taxable brokerage, which are not counted as ordinary income. It is likely to be higher if you have a long career of rising earnings ahead of you, if tax rates rise, or if required distributions from a large traditional balance will push you into a higher bracket at 75 than you ever occupied while working.
The last scenario is the one people miss. A household that spends thirty years maxing out a traditional 401(k) and a traditional IRA can arrive at retirement with a required distribution larger than the salary it was trying to replace. That is a good problem to have, and it is still a problem, solved by holding some Roth money.
- Traditional, 12% tax at withdrawal
- Roth, taxed twice as much on the way in
| Year 10 | Year 20 | Year 30 | |
|---|---|---|---|
| Traditional, 12% tax at withdrawal | 109,000 | 350,000 | 766,000 |
| Roth, taxed twice as much on the way in | 85,000 | 273,000 | 662,000 |
The traditional account wins here because the withdrawal rate is lower than the contribution rate. Flip those two numbers and the lines cross.
Illustrative. $7,500 a year for 30 years at 8% annual return, $7,500 net of 22% tax contributed to the Roth, traditional balance reduced by 12% at withdrawal. No fees, no state tax, no inflation adjustment.
Where the money goes either way
Underneath the tax question, both accounts are just wrappers. What is inside them decides most of the outcome.
A three-fund portfolio — a total US market fund, a total international fund, and a bond fund — covers essentially the whole market at a blended expense ratio under 0.10%. The specific funds matter far less than the fact that you actually buy something: a large share of IRA accounts sit in cash because the contribution was made and the investment step was postponed. Cash in a retirement account for thirty years is a five-figure mistake that takes no effort to make.
The order to fill the accounts
Households rarely have enough to max everything, so the order matters more than the choice between account types.
The 401(k) match, in full
An instant return no market can match, and it beats every tax argument.
The HSA, if you have a high-deductible plan
Deductible in, tax-free growth, tax-free out for medical costs.
The Roth IRA, if your income allows
$7,500 of after-tax money growing for decades without a tax bill.
The 401(k) up to the limit — $24,500 for 2026
Traditional contributions cut your taxable income now.
A taxable brokerage account
No limits, no restrictions, and long-term capital gains rates that can be 0%.
