Roth vs Traditional IRA: How to Choose

A Traditional IRA and a Roth IRA hold the same kinds of investments and share the same annual contribution limit. The entire decision comes down to one question: would you rather get a tax break now, or tax-free withdrawals later?

Traditional IRA: tax break today

Contributions to a Traditional IRA are typically tax-deductible in the year you make them (subject to income and workplace-plan rules), which lowers your taxable income now. In exchange, withdrawals in retirement — both your original contributions and all the growth — are taxed as ordinary income.

Roth IRA: tax-free tomorrow

Roth contributions are made with money you've already paid tax on, so there's no deduction today. The trade-off is that qualified withdrawals in retirement, including all the growth your investments have earned over the decades, come out completely tax-free. Roth IRAs also have income limits on who can contribute directly.

	Traditional IRA	Roth IRA
Tax on contribution	Often deductible now	None — already taxed
Tax on withdrawal	Taxed as ordinary income	Tax-free if qualified
Required withdrawals	Generally required starting at a certain age	Not required during the original owner's lifetime
Best when	You expect a lower tax rate in retirement than today	You expect a similar or higher tax rate in retirement than today

The simple heuristic

A common rule of thumb: if you're early in your career and likely in a lower tax bracket now than you'll be later, Roth tends to make more sense, since you're paying tax at today's lower rate. If you're in your peak earning years and expect a lower tax bracket in retirement, a Traditional IRA's upfront deduction often wins. Nobody can predict future tax rates with certainty, which is exactly why many people split contributions between both account types to hedge the uncertainty.

It's one piece of a bigger plan

Whichever account type you use, the growth math works the same way — years invested, contribution amount, and return assumption all compound together. Our retirement and FIRE calculator lets you project that growth regardless of which account structure you choose, so you can focus the account decision purely on taxes.
