Choosing between a Roth IRA and a Traditional IRA comes down to one question: do you want your tax break now or later? Both are powerful, tax-advantaged retirement accounts — they just tax your money at different times. This guide explains the difference in plain English so you can decide which fits your situation.
The core difference: pay tax now or later
- A Roth IRA is funded with after-tax dollars. You don’t get a deduction today, but your money grows tax-free and qualified withdrawals in retirement are tax-free.
- A Traditional IRA may be funded with pre-tax dollars (a deduction today), grows tax-deferred, and withdrawals in retirement are taxed as ordinary income.
That single trade-off — tax-free later vs. deductible now — drives almost every decision between the two.
Side-by-side comparison
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax on contributions | After-tax (no deduction) | Often deductible now |
| Growth | Tax-free | Tax-deferred |
| Withdrawals in retirement | Tax-free (qualified) | Taxed as income |
| Income limits to contribute | Yes | No (deduction may phase out) |
| Required minimum distributions | Not during your lifetime | Yes, starting at the IRS age |
| Best for | Higher tax bracket expected later | Wanting a deduction today |
Who each account tends to suit
A Roth IRA often makes sense if you’re early in your career, in a relatively low tax bracket today, and expect your income — and tax rate — to rise. Paying tax now at a lower rate can beat paying it later at a higher one. Roth accounts also skip required minimum distributions during your lifetime, which adds flexibility.
A Traditional IRA can suit you if you want to lower your taxable income today, or you expect to be in a lower tax bracket in retirement than you are now.
How to open one
Opening an IRA takes minutes at most major brokerages. You’ll pick the account type, fund it, and choose investments — many beginners start with a low-cost index fund. See our roundup of the best investing apps for beginners to compare options, and use the Retirement Savings Calculator and 401(k) Calculator to project your bigger picture.
The bottom line
Roth or Traditional, the most important step is simply to start contributing and invest the money. Choose Roth for tax-free income later, Traditional for a deduction now — and if you’re unsure, many people lean Roth early in their careers for the long-term flexibility.
