Roth IRA vs. Traditional IRA: How to Choose

Two things about this decision changed for 2026, and one of them has a deadline.

The IRA contribution limit rose to 7,500 dollars, and the catch-up contribution for people 50 and over rose to 1,100 dollars. That second number is quietly historic: the catch-up had been stuck at 1,000 dollars, unindexed, since 2006. The SECURE 2.0 Act indexed it, and 2026 is the first year it has ever moved.

The deadline is the Saver’s Credit. Tax year 2026 is the last year it will be available for retirement contributions, because it is replaced from 2027 by a different mechanism. More on that below, because for people who qualify it is the single largest number in this article.

The 2026 numbers

All from IRS Notice 2025-67, announced in November 2025:

The 7,500 dollar limit is a combined cap across both account types. You can split it between a Roth and a traditional IRA; you cannot contribute 7,500 to each.

The actual question

Strip away everything else and the choice is a bet on one variable: whether your tax rate in retirement will be higher or lower than your tax rate now.

A traditional IRA contribution may be deductible now and is taxed on the way out. A Roth contribution is made with taxed money and, once qualified, comes out tax free. If your rate is higher later, the Roth wins. If it is lower later, the traditional wins. Everything else in this article is detail on top of that sentence.

What makes it decidable rather than a coin flip is that some situations point clearly one way:

One income limit surprises people every year: for a married couple where one spouse is covered by a workplace plan and the other is not, the uncovered spouse’s deduction phases out at 242,000 to 252,000 dollars, far above the 129,000 to 149,000 range that applies when the contributor is the covered one. Being married to someone with a 401(k) does not disqualify you the way people assume.

The credit that is about to disappear

The Saver’s Credit is worth up to 1,000 dollars per person, or 2,000 for a couple, on the first 2,000 dollars of retirement contributions each. It is non-refundable and claimed on Form 8880. For 2026 the thresholds are:

Look at the top-left cell. A couple earning under 48,500 dollars who contribute 2,000 dollars each receive a 2,000 dollar credit, which is a 50 percent immediate return before any investment gain. Very little in personal finance does that.

From 2027 this is replaced by the Saver’s Match, under Section 6433 of the tax code, created by the SECURE 2.0 Act and effective for taxable years beginning after 31 December 2026. It works differently and, for many people, better: rather than reducing a tax bill, Treasury pays the match directly into your IRA or retirement plan account. The amount is 50 percent of up to 2,000 dollars of contributions, so a maximum of 1,000 dollars per person, with 2027 phase-outs beginning at 41,000 dollars for joint filers, 30,750 for head of household and 20,500 for single filers.

The difference matters most for people with little or no tax liability, for whom a non-refundable credit was worth nothing. A deposit is worth something regardless.

The practical consequence: if you qualify for the Saver’s Credit, 2026 is the last year to use it, and it is claimed on the return you file for this year.

The two five-year rules, which are not the same rule

Roth accounts have two five-year clocks and conflating them causes real errors.

The contribution five-year rule determines whether your earnings come out tax free. The period begins on the first day of the taxable year for which you made your first Roth contribution, so a contribution made in April 2026 for tax year 2025 starts the clock on 1 January 2025. There is one clock per taxpayer, not one per account. A distribution is qualified only if that period is satisfied and one of four conditions is met: you are 59 and a half or older, disabled, the distribution is to a beneficiary after death, or it is a first-time home purchase up to a 10,000 dollar lifetime maximum.

The conversion five-year rule is a different thing entirely. It runs separately for each conversion and governs whether the 10 percent additional tax applies to converted amounts withdrawn early. It stops mattering once you reach 59 and a half.

Worth knowing alongside them: Roth distributions follow ordering rules. Contributions come out first, then conversions and rollovers, then earnings last. That is why your own contributions are accessible without tax or penalty at any time, which is the feature that makes a Roth double as a reluctant emergency reserve.

Required minimum distributions, and the date almost everyone gets wrong

The current starting age is 73. The statute, as amended by the SECURE 2.0 Act, says that someone who attains age 72 after 31 December 2022 and age 73 before 1 January 2033 has an applicable age of 73, and that someone who attains age 74 after 31 December 2032 has an applicable age of 75.

Which means the widely repeated line that the RMD age rises to 75 in 2033 is wrong. The statute keys off attaining age 74 after the end of 2032, which describes people born in 1960 or later. Someone born in 1960 turns 75 in 2035. Nobody takes a first required distribution at 75 in 2033.

There is also a genuine drafting gap: people born in 1959 satisfy both conditions, the regulation leaves that year reserved, and the IRS has proposed treating them as 73. That remains a proposal rather than settled law.

Two further points. Roth IRAs have no required distributions for the original owner, which is a real planning advantage. And since 2024, Roth 401(k) accounts no longer have pre-death required distributions either, which removed the old reason to roll one into a Roth IRA purely to escape them. The penalty for missing a required distribution is a 25 percent excise tax, reduced to 10 percent if corrected within the correction window, down from 50 percent before SECURE 2.0.

Getting at the money early

The 10 percent early distribution tax has a long exception list, and two of the exceptions are recent enough that most guides omit them.

Available only from IRAs: a first-time home purchase up to 10,000 dollars lifetime, qualified higher education expenses with no dollar cap, and health insurance premiums while unemployed.

Available from IRAs and plans: age 59 and a half, death, total and permanent disability, substantially equal periodic payments, unreimbursed medical expenses above 7.5 percent of adjusted gross income, an IRS levy, qualified military reservist distributions, birth or adoption up to 5,000 dollars per child, and, for distributions after 31 December 2023, an emergency personal expense distribution of up to the lesser of 1,000 dollars or the vested balance over 1,000 dollars, once per calendar year, and a domestic abuse victim distribution of up to the lesser of 10,000 dollars, indexed, or 50 percent of the account.

One trap: for a SIMPLE IRA the rate is 25 percent, not 10, within the first two years of participation.

If your income is over the limit

Contributing to a traditional IRA and converting it, commonly called a backdoor Roth, remains available. The obstacle is the pro-rata rule at Section 408(d)(2) of the tax code, which requires all your individual retirement plans to be treated as one contract. You cannot isolate after-tax dollars and convert only those. The balance is measured at 31 December of the conversion year, not at the date of conversion.

Workplace 401(k) balances are not included in that aggregation, which is why the manoeuvre is clean for some people and messy for others. Nondeductible contributions and conversions are reported on Form 8606.

What to do, in order

1. Check the Saver’s Credit thresholds first. At the 50 percent tier it dwarfs the Roth-versus-traditional question, and 2026 is its final year.
2. Work out whether your rate is likely higher or lower later. That is the decision; everything else is detail.
3. Check the phase-out that applies to you, including the higher one if your spouse rather than you is covered by a workplace plan.
4. If you are unsure, split the contribution. Hedging a genuinely unknowable variable is reasonable.
5. Start the Roth clock early even with a small contribution, because the five-year period runs from your first contribution year, not from each deposit.
6. If you are over the income limit, check your existing IRA balances before converting, since the pro-rata rule decides whether a backdoor conversion is clean or expensive.

What is worth noticing about the 2026 rules is how much of the benefit is concentrated at the bottom of the income range and how little publicity it gets. A couple earning 45,000 dollars can receive 2,000 dollars back on 4,000 dollars saved, and take-up of that credit has always been poor. The Roth-versus-traditional debate absorbs enormous attention for a decision that turns on a tax rate nobody can forecast, while a 50 percent match sits unclaimed on the same form.
