Roth IRA vs Traditional IRA: which one is better for you?

Short answer: choose a Roth IRA if you expect to pay the same or a higher tax rate in retirement than you do today, and a Traditional IRA if you expect a lower rate. A Roth taxes your money now and lets it grow and be withdrawn tax-free. A Traditional IRA may give you a tax deduction now and taxes withdrawals later. For 2026 the IRA contribution limit is $7,500 ($8,600 if you are 50 or older), shared across all your IRAs.

What is the actual difference between a Roth and a Traditional IRA?

Both are accounts you open yourself at a brokerage, and both let investments grow without yearly tax on dividends or gains. The difference is only when you pay income tax on the money:

	Traditional IRA	Roth IRA
Tax when you contribute	Possibly deductible, so you pay less tax now	No deduction, you contribute after-tax money
Tax while it grows	None	None
Tax when you withdraw in retirement	Ordinary income tax on everything you take out	None on qualified withdrawals
Required withdrawals	Yes, starting at age 73 or 75 depending on your birth year	None for the original owner
Income limit to contribute	None, but the deduction phases out if you have a workplace plan	Yes. For 2026, roughly $153,000 to $168,000 single and $242,000 to $252,000 married filing jointly
Early access	10% penalty plus tax before 59½, with exceptions	Contributions can be withdrawn any time, earnings face rules

Limits are adjusted every year, so confirm the current numbers on IRS.gov before you contribute.

How do you decide: tax now or tax later?

The whole choice reduces to one question: is your tax rate likely to be higher or lower when you withdraw than it is today?

Early in your career, in a lower bracket: a Roth usually wins. You pay tax at today's low rate and never again, and decades of growth are tax-free.
At a peak-earning stage in a high bracket: a Traditional IRA (or a pre-tax 401(k)) usually wins, because the deduction is worth more at a high rate.
Genuinely unsure: split between both. Having some tax-free and some tax-deferred money gives you flexibility to manage your tax bill in retirement.

A rough worked example: you contribute $7,000 and it grows at 7% a year for 30 years, to about $53,300. In a Roth, that $53,300 is yours, tax-free. In a Traditional IRA, if you withdraw it at a 22% rate you keep about $41,600, but you also saved 22% on the original $7,000 (about $1,540) at the start. If your rate in retirement is also 22%, the two come out the same. The Roth wins if your future rate is higher, the Traditional wins if it is lower. That is the entire mechanism.

What about the income limits and the backdoor Roth?

If your income is above the Roth limit, you cannot contribute to a Roth IRA directly. Many higher earners use a "backdoor Roth": they make a non-deductible contribution to a Traditional IRA and then convert it to a Roth. It is legal and common, but the pro-rata rule can create an unexpected tax bill if you also hold other pre-tax IRA money. If that applies to you, talk to a tax professional before converting.

Which withdrawals from a Roth are really tax-free?

Your contributions can come out at any time without tax or penalty, because you already paid tax on them. Earnings are tax-free only when the withdrawal is "qualified": you are at least 59½ and the account has been open for five tax years. A first-time home purchase can also qualify for up to $10,000 of earnings. This flexibility is why a Roth can double as a backup emergency source, though touching it should be a last resort because every dollar removed loses its future tax-free growth.

Common mistakes to avoid

Contributing but never investing it. An IRA is an account, not an investment. Cash sitting in it earns very little. Choose the investments, for example a broad index fund.
Skipping the employer match to fund an IRA. If your 401(k) matches your contributions, capture the full match first, because it is an immediate return no IRA can beat.
Going over the limit. The limit applies across all your IRAs combined, and excess contributions carry a 6% yearly penalty until corrected.
Forgetting the spousal option. A non-working spouse can have an IRA funded from the working spouse's income, if you file jointly.

How to put this to work

Pick the account type with the tax-now-or-later question, automate a monthly amount that adds up to your yearly goal, and choose a low-cost diversified fund.

Frequently asked questions

Can I have both a Roth IRA and a Traditional IRA?

Yes. You can hold both, but the yearly contribution limit ($7,500 for 2026, or $8,600 if you are 50 or older) applies to the combined total across all your IRAs, not to each account separately.

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

They do different jobs and most people benefit from both. A 401(k) has a much higher limit and often an employer match, which you should capture first. A Roth IRA adds tax-free growth, more investment choices and more flexible access to contributions.

What happens if my income is too high for a Roth IRA?

You cannot contribute directly once your income passes the phase-out range, but you may still use a backdoor Roth conversion. The pro-rata rule can make that taxable if you hold other pre-tax IRA money, so check with a tax professional first.

Do I have to take required minimum distributions from a Roth IRA?

No. The original owner of a Roth IRA has no required minimum distributions, which makes it useful for leaving money to heirs or for keeping tax-free growth going as long as you like. Traditional IRAs do require withdrawals, starting at age 73 or 75 depending on your birth year.

Which is better if I am young and earn a modest income?

Usually a Roth IRA. A lower bracket today means paying tax now is cheap, and you get decades of tax-free growth. As your income rises, shifting new savings toward pre-tax accounts can make sense.
