Roth IRA vs. Traditional IRA: Which Is Better for You?
The key differences between Roth and traditional IRAs, including taxes, withdrawals and who each one suits best.
Individual Retirement Accounts (IRAs) are among the most powerful tools for building retirement savings in the U.S., and the biggest decision is which type to use: Roth or traditional. The short version is that it comes down to when you'd rather pay taxes: now, or in retirement. Here's a clear breakdown to help you decide.
This guide covers U.S. IRAs. Contribution limits, income limits and deduction rules are set by the IRS and change periodically, so always check the current figures on IRS.gov before contributing. In the UK, the closest equivalents are ISAs and pensions; in Canada, TFSAs and RRSPs.
The core difference: pay taxes now or later
- Traditional IRA: contributions may be tax-deductible now, your money grows tax-deferred, and you pay ordinary income tax when you withdraw in retirement.
- Roth IRA: you contribute money you've already paid tax on, your money grows tax-free, and qualified withdrawals in retirement are tax-free.
Think of it this way: a traditional IRA gives you a tax break today; a Roth IRA gives you a tax break later.
Side-by-side comparison
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Tax break | Now (contributions may be deductible) | Later (qualified withdrawals are tax-free) |
| Growth | Tax-deferred | Tax-free |
| Income limits to contribute | None to contribute (deduction may be limited if you have a workplace plan) | Yes, eligibility phases out at higher incomes |
| Withdrawing contributions early | Generally taxed, plus a 10% penalty before age 59½ unless an exception applies | Your original contributions can be withdrawn at any time, tax- and penalty-free |
| Required minimum distributions | Yes, starting at an age set by law | None during the original owner's lifetime |
When a Roth IRA often makes sense
- You expect a higher tax rate in retirement than today, for example if you're early in your career.
- You're currently in a low tax bracket. Paying tax now at a low rate can be a good deal.
- You value flexibility. Being able to withdraw contributions (not earnings) without penalty makes a Roth more forgiving.
- You want tax diversification, a source of tax-free income in retirement alongside taxable accounts.
- You'd like to avoid required minimum distributions.
When a traditional IRA often makes sense
- You're in a high tax bracket now and expect a lower one in retirement.
- You want to lower your taxable income this year, for example to qualify for other tax credits.
- Your income is too high to contribute to a Roth directly.
- You qualify for the deduction. If you or your spouse have a workplace retirement plan, the deduction may be reduced or eliminated at certain income levels.
Important rules to know
Contribution limits
There's an annual limit on how much you can contribute across all your IRAs combined, plus an extra "catch-up" amount if you're 50 or older. You also generally need earned income at least equal to what you contribute. The limits are adjusted for inflation, so check IRS.gov for this year's numbers.
Roth income limits
Your ability to contribute directly to a Roth IRA phases out above certain income levels, which depend on your tax filing status. Some higher earners use a strategy called a "backdoor Roth" (contributing to a traditional IRA and then converting), which has tax rules worth reviewing with a professional.
The Roth five-year rule
For Roth earnings to be withdrawn tax-free, you generally must be at least 59½ and your first Roth IRA contribution must have been made at least five tax years earlier. Your contributions themselves can always come out tax- and penalty-free.
Early withdrawal penalties
Withdrawing from a traditional IRA (or Roth earnings) before 59½ usually triggers income tax plus a 10% additional tax, though the IRS lists exceptions such as certain first-time home purchases, qualified education expenses and disability.
Can you have both?
Yes. You can contribute to both a Roth and a traditional IRA in the same year, as long as your combined contributions stay within the annual limit. Splitting contributions is a reasonable way to hedge if you're unsure what your future tax rate will be.
Where an IRA fits in your plan
A common order of priorities for retirement saving is:
- Contribute enough to your workplace plan to get the full employer match. See 401(k) basics.
- Fund an IRA (Roth or traditional).
- Go back and contribute more to your workplace plan.
- Invest in a regular taxable brokerage account.
Inside your IRA, many people use low-cost, diversified funds. See our guide to index funds for beginners. And before investing heavily, make sure you have an emergency fund in place.
Bottom line: Choose a Roth if you'd rather pay taxes now and enjoy tax-free withdrawals later; choose traditional if you want the tax break today. If you're unsure, splitting contributions between both is a sensible middle ground. Either way, starting early matters more than picking perfectly.
Frequently asked questions
Can I have both a Roth IRA and a traditional IRA?
Yes. You can contribute to both in the same year as long as your combined contributions don't exceed the annual IRA limit set by the IRS.
Can I withdraw money from a Roth IRA early?
Your original contributions can generally be withdrawn at any time without tax or penalty. Earnings withdrawn early may be taxed and penalized unless an exception applies.
Is a Roth IRA better for young people?
Often, because many younger workers are in lower tax brackets now than they expect to be later. Paying tax at today's lower rate can be an advantage.
What happens if I earn too much for a Roth IRA?
You can still contribute to a traditional IRA. Some higher earners use a backdoor Roth conversion, which has tax rules worth reviewing with a professional.
