Roth vs traditional: which is better for you?

Roth is usually better if your tax rate today is lower than the rate you expect when you take the money out. Traditional is usually better if your rate today is higher. If you can't tell, splitting between the two is a reasonable answer, not a cop-out.

The choice has the same shape in a 401(k), 403(b), 457(b) or the TSP as it does in an IRA. Both kinds grow without yearly tax. The only difference is when you pay income tax: on the way in (Roth) or on the way out (traditional). Here's how to think it through, with a made-up example you can follow with a pencil.

This is general education, not tax or financial advice. Your own tax return, your plan's rules and your state's tax laws decide what's right for you. A tax preparer or fee-only planner can run your real numbers.

Figures checked October 24, 2026 against IRS.gov: the 2026 limits release (IR-2025-111) for contribution limits, Roth IRA income limits and traditional IRA deduction ranges; the IRS Roth comparison chart; the IRS required minimum distribution FAQs; the IRS catch-up contributions page; and Publication 590-B. The IRS hadn't published 2027 limits yet when we checked.

The one question that decides most of it

Will your tax rate be higher now, or when you take the money out?

• Higher now (peak earning years, a high-tax state you plan to leave): traditional tends to win. You skip tax at a high rate and pay it later at a lower one.
• Higher later (early career, a low-income year, expecting big pensions or required withdrawals): Roth tends to win. You pay at today's low rate and never again on that money.
• About the same: it's close to a tie, and the smaller points below can decide it.

The rate that matters is your marginal rate, the bracket your last dollars fall into, not your average rate. A traditional contribution comes off the top of your income, so it saves tax at your highest bracket. Later, withdrawals stack on top of your other retirement income, often starting in a lower bracket.

A made-up example

Jordan (invented for this guide) has $5,000 of pay set aside to save this year and is in the 22% federal bracket. Say the investments triple by the time Jordan retires.

Same rate now and later? A tie, to the dollar. Lower rate later? Traditional wins. Higher rate later? Roth wins. Growth doesn't change which one wins. It only makes the gap bigger.

One catch: this compares the same $5,000 of pay. If Jordan puts the full $5,000 into a Roth and pays the $1,100 of tax from other money, the Roth holds more after-tax value under the same limit. So if you're already saving the maximum, Roth lets you shelter a bit more.

Signs Roth may suit you

• You're early in your career, or in a low-income year (school, a career change, part-time work, time at home with kids).
• You expect a sizeable pension, rental income or large traditional balances, so your income in retirement could be as high as it is now.
• You'd like money that doesn't count as taxable income later. Qualified Roth withdrawals don't make more of your Social Security taxable, and they don't push up the income Medicare uses for IRMAA premiums.
• You want flexibility before 59½. Your own Roth IRA contributions (not the growth) can come out at any time without tax or the 10% additional tax (IRS Publication 590-B).
• You'd like to leave money to someone. Roth IRAs have no required withdrawals while you're alive.

Signs traditional may suit you

• You're in your highest-earning years.
• You live in a state with income tax now and may retire somewhere with less or none.
• You plan to stop work early and expect several low-income years before Social Security and required withdrawals start.
• The tax break today helps you save at all. A deduction you can feel this year beats a tax-free withdrawal you never get round to funding.
• A lower taxable income now could help you qualify for credits, such as the Saver's Credit or other income-based benefits.

The early-retiree angle

People aiming for FIRE often lean traditional while they're working, for one reason: the gap years. Between the last paycheck and Social Security, many have very little taxable income. The standard deduction alone shelters part of what they take out, and the next dollars are taxed at the lowest brackets.

That's also the window for moving money from traditional to Roth at a low rate, a Roth conversion. Done over several years, it can shrink the traditional balances that required minimum distributions are figured on later. Getting to your money before 59½ covers the routes people use to reach traditional savings early, including the conversion ladder.

None of this is guaranteed. Tax law can change, and so can your plans. That uncertainty is one of the best arguments for having some of each.

The 2026 rules in plain English

Contribution limits (shared between Roth and traditional)

Source: [IRS](https://www.irs.gov/newsroom/401k-limit-increases-to-24500-for-2026-ira-limit-increases-to-7500), 2026 limits. Our [catch-up contributions guide](/how-to-get-fire/catch-up-contributions-after-50) goes deeper on the extra amounts.

The limit is the same dollar figure either way. You can split it, for example $12,000 Roth and $12,500 traditional in your 401(k), if your plan offers both.

Roth IRA income limits

You can put the full amount into a Roth IRA if your modified AGI is under the start of the range, a smaller amount within it, and nothing above it:

A Roth 401(k) has no income limit (IRS), so higher earners whose plan offers one can still save Roth at work.

When a traditional IRA is deductible

Anyone with earned income can put money into a traditional IRA. Whether you can deduct it depends on your income if you, or your spouse, are covered by a retirement plan at work:

If neither of you has a workplace plan, the deduction has no income limit. A traditional IRA contribution you can't deduct gives you the downsides of both kinds (taxed going in, growth taxed coming out), so it's worth checking this before you choose.

The new Roth catch-up rule for higher earners

Starting in 2026, if your wages from your employer were more than $150,000 last year, any catch-up contributions you make in that employer's plan must go in as Roth (IRS). Your regular $24,500 can still be traditional.

Qualified withdrawals and the five-year rule

For Roth withdrawals to be completely tax-free, the account generally has to have been open at least five years, and you have to be 59½ or older (or disabled, or the money is paid after your death) (IRS). Starting a Roth early, even with a small amount, starts that clock.

Required withdrawals

Traditional IRAs and 401(k)s require minimum withdrawals starting at 73. Roth IRAs have none while you're alive, and since 2024, neither do Roth accounts in 401(k) and 403(b) plans (IRS).

What about an employer match?

The match usually goes in pre-tax, whichever you pick for your own money. Some plans now let you choose Roth for vested matching money, which counts as taxable income in the year it goes in. Either way, getting the full match comes first. Our 401(k) match guide explains how.

A simple plan for this month

1. Find your marginal federal tax bracket from last year's return or tax software.
2. Make a rough guess at your retirement income: Social Security, any pension, and what you'll draw from savings.
3. If today's rate is clearly higher, lean traditional. Clearly lower, lean Roth. Not sure? Split it.
4. Check whether your workplace plan offers a Roth option, and whether your income allows a Roth IRA or a deductible traditional IRA.
5. Set the split in your plan or IRA, and put a note in your calendar to look again each January, or whenever your income changes a lot.

Common questions

Is Roth or traditional better for young people?

Often Roth, because early-career income is usually lower than it will be later, so the tax paid now is at a lower rate. It isn't automatic. Someone already in a high bracket, or planning a long low-income stretch in early retirement, may still do better with traditional for part of their savings.

Can I have both a Roth and a traditional account?

Yes. Many people hold both, and many workplace plans let you split each paycheck between Roth and pre-tax contributions. The annual limit is shared, so $24,500 is the total for your own 401(k) contributions in 2026, and $7,500 is the total across all your IRAs.

What are the 2026 Roth IRA income limits?

For 2026, the amount you can put into a Roth IRA phases out with modified AGI between $153,000 and $168,000 for single filers and heads of household, and between $242,000 and $252,000 for married couples filing jointly. Roth 401(k) contributions have no income limit.

Is a Roth 401(k) better than a traditional 401(k)?

Neither is better for everyone. Roth tends to come out ahead if your tax rate when you withdraw will be higher than it is now, and traditional if it will be lower. If the rates are the same, they come out about even. Many people split their contributions because they can't know their future rate.

Do Roth accounts have required minimum distributions?

Not while you're alive. Roth IRAs never had them for the original owner, and since 2024, Roth accounts in 401(k) and 403(b) plans don't either. Traditional IRAs and 401(k)s generally require withdrawals starting at age 73. Heirs who inherit any of these accounts have their own withdrawal rules.

Can I take money out of a Roth IRA before 59½?

You can take out what you contributed at any time, without tax or the 10% additional tax. Earnings are different: taking them out before 59½, or before the account is five years old, can mean income tax and the 10% additional tax unless an exception applies.
