Traditional IRA vs. Roth IRA: Understanding the Tax Difference

A traditional IRA may give you a tax break now, and you pay tax when you take the money out. A Roth IRA gives no break now, but your withdrawals in retirement are tax-free. If your tax rate will be lower in retirement, traditional tends to win; if it will be higher, Roth tends to win.

1. First, what is an IRA?

An IRA (individual retirement account) is a retirement account you open on your own at a bank, brokerage or investing app, not through your job. That company is called your custodian, and opening an account online often takes about 15 minutes.

Think of an IRA as a box. You put money in, then choose what goes inside: funds, stocks or bonds. The box itself doesn't earn anything; the investments do.

To put money in, you need taxable compensation. That's pay you earn from work, like wages or self-employment income. Interest, rent and investment gains don't count. You can't put in more than you earned that year.

2. How a traditional IRA works

With a traditional IRA, you may get to subtract your contribution from your income at tax time. This is a tax deduction. It lowers the income you pay tax on this year.

While your money stays in the IRA, you don't pay tax on its growth each year. When you take money out in retirement, it's taxed as regular income.

Anyone with taxable compensation can put money in a traditional IRA, at any income. A high income only affects whether you get the deduction (see section 5). Starting at 73, you must take a minimum amount out each year. These are required minimum distributions (RMDs).

3. How a Roth IRA works

With a Roth IRA, you put in money you've already paid tax on. You get no deduction today.

In return, your withdrawals in retirement are tax-free, growth included. A withdrawal that meets the age and five-year rules (see section 7) is called a qualified distribution. You also never have to take RMDs from your own Roth IRA.

There's a catch: higher earners can't put money into a Roth IRA directly. The limit uses your modified adjusted gross income (MAGI). That's the income figure the IRS uses to check limits. For most people, it's close to the adjusted gross income on their tax return.

4. Side-by-side comparison

Question	Traditional IRA	Roth IRA
Tax break when you put money in?	Often, depending on income and workplace plans	No
Tax on growth each year?	No	No
Tax when you withdraw in retirement?	Yes, taxed as income	No, if qualified
Income limit to contribute?	No	Yes; for 2026, phases out at $153,000–$168,000 (single)
Required withdrawals?	Yes, starting at 73	No, not while you're alive
Take out your contributions early?	Taxed, plus usually a 10% penalty	Yes, any time, no tax or penalty

5. 2026 limits and income rules

The contribution limit

For 2026, you can put up to $7,500 into IRAs, or $8,600 if you're 50 or older. That's one limit shared by all your IRAs, traditional and Roth. You can't put $7,500 in each.

You have until the tax-filing deadline, usually April 15, to make contributions for the year before. A filing extension doesn't give you more time. Putting money in between January and April? Tell your custodian which year it's for.

Who can contribute to a Roth IRA

The amount you can put into a Roth shrinks inside a phase-out range. That's an income range where your allowed amount drops step by step to zero.

Filing status	2026 Roth IRA phase-out (MAGI)
Single or head of household	$153,000–$168,000
Married filing jointly	$242,000–$252,000
Married filing separately	$0–$10,000

Who can deduct a traditional IRA contribution

This depends on whether you or your spouse has a retirement plan at work, like a 401(k).

No workplace plan for you or your spouse? Your whole contribution is deductible at any income.
You have a workplace plan. The deduction phases out for 2026 at $81,000–$91,000 (single or head of household) or $129,000–$149,000 (married filing jointly).
You don't have a plan, but your spouse does. The deduction phases out at $242,000–$252,000 (married filing jointly).
Married filing separately and covered. The deduction phases out at $0–$10,000.

Here's an example. Kevin is single, has a MAGI of $86,000 and has a 401(k) at work. He's halfway through the $81,000–$91,000 range. So he can deduct about half of a $7,500 contribution, or $3,750. His friend Tasha earns the same but has no plan at work. She can deduct all $7,500.

Spousal IRAs

If you're married, file jointly and one of you earns little or nothing, you can still both save. A spousal IRA lets the lower earner contribute based on the working spouse's pay. Together, you can't put in more than your combined pay on the joint return.

6. The fair comparison: which leaves you more?

Here's the surprise. If your tax rate is the same now and in retirement, both choices leave you with the same spending money.

Priya is in the 22% bracket and has $1,000 of pay to save.

Traditional (deductible): All $1,000 goes in.
Roth: She pays $220 of tax first, so $780 goes in.

Both grow 6% a year for 25 years. The traditional IRA grows to about $4,292. After 22% tax, she keeps about $3,348. The Roth grows to about $3,348, all hers. It's a tie.

Now change one thing. If Priya's rate drops to 12% in retirement, the traditional IRA leaves her about $3,777, so traditional wins. If her rate goes up instead, Roth wins.

A simple rule of thumb

Lean Roth if you're in a low bracket now (10% or 12%), early in your career or expect to earn more later.
Lean traditional if you're in a high bracket now and can get the full deduction, and you expect lower income in retirement.
Not sure? Many people use both, or pair a traditional 401(k) with a Roth IRA. Having both kinds is called tax diversification. It gives you choices about which pot to draw from later.

One more thing: if you can't deduct a traditional IRA contribution, a Roth is usually the simpler choice, as long as you're under the Roth income limit.

7. Taking money out early

IRAs are built for retirement. Here's how each one treats early withdrawals.

Traditional IRA

Money you take out is taxed as income. Before 59½, you usually owe an extra 10% tax too.

Roth IRA

A Roth IRA pays money out in a set order:

Your contributions come out first. They're always tax- and penalty-free.
Conversions come out next, oldest first (see section 8).
Earnings come out last. Taken early, they're taxed, plus 10% if you're under 59½.

Your Roth IRA's five-year clock starts January 1 of the tax year of your first Roth IRA contribution. One clock covers all your Roth IRAs. Earnings come out tax-free once five tax years have passed and you're 59½, disabled or using up to $10,000 for a first home. They're also tax-free when paid to your heirs after your death.

You can take out what you put in at any time, but then it's gone from your retirement savings. You can't put it back later beyond the yearly limit.

Exceptions to the 10% penalty

For IRAs, the 10% penalty doesn't apply in the cases below. You still owe income tax on any traditional money or Roth earnings you take out.

Up to $10,000 (lifetime) for a first home
College costs for you, your spouse, kids or grandkids
Health insurance while you're unemployed
Total and permanent disability
Up to $5,000 per child for a birth or adoption
One emergency withdrawal a year, up to $1,000
Medical bills above 7.5% of your adjusted gross income

Note: the age-55 rule that helps people who leave a job applies to 401(k)s, not IRAs.

8. Roth conversions and the backdoor Roth

A Roth conversion moves money from a traditional IRA (or old 401(k)) into a Roth IRA. You pay income tax on the pre-tax money you move, in the year you move it. After that, it grows tax-free.

Each conversion has its own five-year clock for the 10% penalty if you're under 59½. That stops people from converting and pulling the money right back out.

The backdoor Roth

Earn too much for a Roth IRA? A backdoor Roth is a legal workaround. You make a nondeductible traditional IRA contribution (one you get no tax break for), then convert it to Roth.

Money you've already paid tax on is called your basis. You track it on IRS Form 8606 with your tax return, so it isn't taxed twice.

Here's the trap. If you have other pre-tax IRA money, the IRS uses the pro-rata rule. It treats all your traditional IRAs as one pot. Say 90% of that pot is pre-tax. Then 90% of anything you convert is taxed, even if you only meant to move the after-tax part. If that's you, talk to a tax pro first.

9. If you're self-employed

You can use a traditional or Roth IRA like anyone else. You may also have accounts with higher limits. A SEP IRA lets you put in a share of your business profit. A solo 401(k) works like a 401(k) for a business owner with no employees besides a spouse. Our guide to business tax basics covers more.

10. If you live in New York

The deduction carries over. New York starts from your federal income, so a deductible traditional IRA contribution also lowers your New York State income tax, plus New York City income tax if you live in the city.
A break in retirement. Once you're 59½, New York lets you exclude up to $20,000 a year of pension and annuity income, which includes IRA withdrawals. That softens the tax on traditional IRA money.
Qualified Roth withdrawals aren't part of your federal income, and New York starts from that number, so New York doesn't tax them either.

Common IRA mistakes

Assuming every traditional IRA contribution is deductible. Check your workplace plan and income first.
Putting $7,500 in each account. The limit is shared between traditional and Roth.
Ignoring the Roth income limit. If you put in money you weren't allowed to, you'll owe a 6% tax each year on the extra until you take it out.
Skipping Form 8606 for nondeductible contributions. Without it, you may pay tax twice.
Forgetting the year. In January through April, tell your custodian which tax year a deposit is for.
Leaving money in cash. A deposit often sits uninvested until you choose a fund.

Frequently asked questions about traditional and Roth IRAs

Can I have both kinds?

Yes. You can have a traditional and a Roth IRA at the same time. Your total contributions to both can't go over $7,500 for 2026 ($8,600 if you're 50 or older).

Can I have a Roth IRA and a 401(k)?

Yes. IRA and 401(k) limits are separate. A workplace plan only affects whether a traditional IRA contribution is deductible, not whether you can open a Roth IRA.

Does a high salary stop me from using a traditional IRA?

No. Anyone with earned income can put money in a traditional IRA. A high income only affects whether you get the deduction.

Is there a tax credit for saving in an IRA?

Yes, if your income is modest. The Saver's Credit cuts your tax bill when you save in an IRA or workplace plan. For 2026, it's open if your adjusted gross income is $40,250 or less (single), $60,375 or less (head of household) or $80,500 or less (married filing jointly).

Does Roth mean no taxes ever?

Not quite. You pay tax on the money before it goes in. And earnings taken out early can be taxed. Follow the rules, though, and your retirement withdrawals are tax-free.

The bottom line

Traditional and Roth IRAs are the same box with different tax timing. Traditional helps more if your tax rate will drop in retirement; Roth helps more if it will rise or stay low now. Check the income limits, pick one (or both) and start with whatever amount you can.
