Roth vs traditional: pay the tax now or later

Illustrative examples, education not advice.

In plain words

Retirement accounts come in two tax flavours.

Traditional (pre-tax). Your contribution lowers your taxable income this year. The money grows without yearly tax. When you take it out in retirement, every dollar is taxed as ordinary income.
Roth (after-tax). You get no deduction now. The money grows, and qualified withdrawals later are tax-free, including all the growth.

The core question is simple: is your tax rate higher now, or will it be higher later? If now, traditional tends to win. If later, Roth tends to win. If they’re about the same, the result is close, and other features decide it.

For a Roth IRA withdrawal of earnings to be tax-free, you generally need to be 59½ or older and have had a Roth IRA open for at least five years. Your own contributions to a Roth IRA can come out at any time without tax or penalty.

How it helps real people

The choice is one of the few tax decisions ordinary workers get to make every paycheck. Getting it roughly right can save thousands over a career.

Roth money also brings features that matter in retirement:

No required minimum distributions for the original owner. Roth IRAs never had them, and since 2024 Roth accounts inside 401(k) and 403(b) plans don’t either.
Tax-free income doesn’t raise your taxable income. That can help keep Social Security benefits less taxed and keep Medicare premiums from rising, because both depend on taxable income.
Heirs usually inherit Roth money tax-free, though most non-spouse heirs must empty an inherited account within 10 years.

Traditional money has its own strengths. The deduction today can be worth a lot in high-earning years, and that saving can be invested. Many retirees also have low-income years where withdrawals are taxed at 10% or 12%.

A worked example

Illustrative. Two friends each set aside $6,000 of pay this year.

Dev, 28, is single and earns $52,000. After the 2026 standard deduction of $16,100, his taxable income is about $35,900, in the 12% bracket. A traditional contribution would save him about $720 in tax. He expects to earn much more later, so he picks Roth. He pays 12% now on money that may grow for 35 years and come out tax-free.

Lena, 52, earns $230,000 as a single filer. Her top bracket is 32% this year. A traditional contribution saves her about $1,920 now. She expects her retirement income to fall into the 22% or 24% bracket, so she picks traditional and plans Roth conversions in her early 60s, when her income drops.

Both are reasonable. The numbers are illustrative only and use 2026 federal brackets for a single filer. They ignore state tax.

Who it’s for

Roth tends to fit:

Younger workers in lower brackets today.
People who expect higher income, a pension or large savings later.
Anyone who wants tax-free money for flexibility, or to leave to heirs.

Traditional tends to fit:

People in their peak earning years and high brackets.
People who expect a much lower income in retirement.
People who will use the tax savings to save more.

Who it’s not for

If you won’t actually invest the tax savings from a traditional contribution, part of its edge disappears.
If you earn above the Roth IRA income limits ($153,000 single, $242,000 married filing jointly start the phase-out in 2026), a direct Roth IRA contribution may not be allowed. A Roth 401(k) has no income limit.

Risks and trade-offs

Nobody knows future tax rates. Laws change. A mix of both hedges your bet.
Roth means less take-home today. For the same contribution, Roth costs more now.
State tax matters. Moving from a high-tax state to a no-tax state in retirement can favour traditional now.
The surviving spouse problem. When one spouse dies, the survivor often files as single, with narrower brackets. Large traditional balances can then be taxed at higher rates.

Common mistakes

All-or-nothing thinking. Many people do best with some of each, so they can choose which bucket to draw from each year in retirement.
Judging by total tax, not marginal tax. What matters is the rate on the next dollar, not your average rate.
Forgetting the five-year rules. Roth earnings withdrawn too early can be taxed.
Ignoring the employer match. Employer matching money may be pre-tax by default, even if you choose Roth for your own deferrals. Some plans now let you elect Roth for employer money too.

FAQs

Can I contribute to both a Roth and a traditional account in one year?

Yes. In a 401(k) you can split your deferrals, as long as the total stays within the $24,500 limit for 2026 (plus catch-up if eligible). In IRAs, the $7,500 limit is shared across all your IRAs.

Is Roth always better for young people?

Often, but not always. A young worker with high income in a high-tax state may still benefit from traditional.

Can I switch later?

Yes. You can change future contributions any time, and you can convert traditional money to Roth by paying tax on it. See Roth conversions.

What happens to Roth money when I die?

A spouse can usually treat it as their own. Other heirs generally have to empty it within 10 years, but qualified withdrawals stay tax-free.

Qualified Roth withdrawals generally don’t count toward the income that decides how much of your Social Security is taxed.
