Option A
Roth IRA
Pay taxes now, withdraw tax-free later.
Best for: Best for investors who expect to be in a higher tax bracket in retirement than they are today.
Option B
Traditional IRA
Reduce your tax bill today, pay taxes in retirement.
Best for: Best for investors who want an immediate tax deduction and expect to be in a lower tax bracket when they retire.
How Each Account Works
Both a Roth IRA and a Traditional IRA are individual retirement accounts designed to help Americans save for retirement with meaningful tax advantages. The core difference lies in when those tax benefits apply.
With a Traditional IRA, contributions may be fully or partially tax-deductible in the year you make them — depending on your income and whether you have access to a workplace retirement plan. Your money then grows tax-deferred, meaning you pay no taxes on gains each year. When you begin withdrawing funds in retirement, those distributions are taxed as ordinary income.
With a Roth IRA, contributions are made with money you've already paid income taxes on — so there's no upfront deduction. The trade-off: your money grows tax-free, and qualified withdrawals in retirement are entirely tax-free, including the earnings.
Both account types are subject to the same annual contribution limit, which the IRS adjusts periodically for inflation. Investors age 50 and older are permitted an additional catch-up contribution each year. For guidance on setting up either type of account, see our practical starting point for first-time investors.
| Criterion | Roth IRA | Traditional IRA |
|---|---|---|
| Tax treatment of contributions | After-tax (no deduction) | Pre-tax (may be deductible) |
| Tax treatment of withdrawals | Tax-free (qualified distributions) | Taxed as ordinary income |
| Income eligibility limits | Yes — phases out at higher incomes | No limit to contribute; deductibility phases out |
| Early withdrawal penalty | Contributions: none; Earnings: 10% before 59½ | 10% before age 59½ (with exceptions) |
| Required Minimum Distributions | None during owner's lifetime | Required starting at age 73 |
| Best tax scenario | Lower tax rate now, higher rate in retirement | Higher tax rate now, lower rate in retirement |
Income Limits, Deductibility, and Eligibility Rules
Not every taxpayer has equal access to both accounts. Understanding the eligibility rules is essential before deciding.
Roth IRA income limits: The IRS sets modified adjusted gross income (MAGI) thresholds that phase out your ability to contribute directly to a Roth IRA. As income rises past those limits, the maximum contribution amount reduces until it reaches zero. These thresholds differ for single filers versus married couples filing jointly.
Traditional IRA deductibility phase-outs: Anyone with earned income can contribute to a Traditional IRA, but the ability to deduct that contribution depends on whether you — or your spouse — participate in a workplace retirement plan like a 401(k), and on your income level. If neither you nor your spouse has access to a workplace plan, contributions are generally fully deductible regardless of income.
What Is a Backdoor Roth IRA?
High-income earners who exceed the Roth IRA income limits may have heard of a strategy called a 'backdoor Roth IRA,' which involves making a non-deductible Traditional IRA contribution and then converting it to a Roth. This is a legitimate strategy recognized by the IRS, but it involves tax complexity — particularly the 'pro-rata rule' if you hold other IRA assets. Anyone considering this approach should work with a qualified tax professional before proceeding.
Regardless of deductibility, non-deductible Traditional IRA contributions still allow your money to grow tax-deferred — which may still be valuable depending on your situation. Consult a qualified tax professional to understand how this applies to your circumstances.
Withdrawal Rules and Required Minimum Distributions
The rules governing when and how you can access your money differ meaningfully between the two account types — and can have a significant impact on retirement income planning.
Traditional IRA: Withdrawals before age 59½ are generally subject to a 10% early withdrawal penalty in addition to ordinary income tax, with limited exceptions. Starting at age 73, account holders must begin taking RMDs — minimum annual withdrawals calculated by the IRS — whether or not the money is needed.
Roth IRA: Because contributions were already taxed, you can withdraw your contributions (not earnings) at any time without penalty. Qualified distributions of earnings — generally those taken after age 59½ and after the account has been open for at least five years — are entirely tax-free. Crucially, Roth IRAs are not subject to RMDs during the original owner's lifetime, offering greater flexibility in retirement.
These differences make the Roth IRA particularly appealing for those who want to preserve assets longer or pass wealth to heirs more efficiently. For a broader look at how IRAs fit alongside other tax-advantaged tools, see tax-advantaged accounts every American household should know about.
Age 73
When Traditional IRA RMDs must begin
The SECURE 2.0 Act raised the required minimum distribution age to 73, giving retirees more time before mandatory withdrawals begin.
5 years
Roth IRA seasoning period for tax-free earnings
To withdraw Roth IRA earnings tax-free, the account must have been open for at least five years and the owner must be at least 59½.
Making the Call: Which Account Fits Your Situation?
The single most important variable in this decision is your current tax rate compared to your expected tax rate in retirement. If you're likely to be in a higher bracket later — perhaps because your income is still growing or because tax rates rise over time — paying taxes now via a Roth IRA may save money in the long run. If you're at your peak earning years and expect a lower income in retirement, deferring taxes through a Traditional IRA may be more advantageous.
Many financial planners note that holding both types of accounts can provide tax diversification — the ability to draw from taxable and tax-free sources strategically in retirement. This is a general concept, not a one-size-fits-all prescription; individual circumstances vary considerably.
It's also worth remembering that IRAs are separate from — and often complementary to — workplace plans. If you're weighing whether retirement savings should come before or alongside liquid savings, understanding the trade-off between saving and investing can help clarify priorities.
