How Each Account Handles Taxes
Both the Roth IRA and the Traditional IRA are individual retirement accounts that allow your investments to grow without being taxed each year — a significant advantage over standard taxable brokerage accounts. The difference lies in when the IRS collects its share.
With a Traditional IRA, contributions may be tax-deductible in the year you make them, depending on your income and whether you or your spouse have access to a workplace retirement plan. You pay no tax on that money until you make withdrawals in retirement, at which point distributions are taxed as ordinary income.
With a Roth IRA, you contribute money you have already paid income tax on — there is no upfront deduction. In exchange, qualified withdrawals in retirement, including all investment growth, are completely tax-free.
Think of it as a choice between a tax break today and a tax break tomorrow. For a broader look at how IRAs fit alongside other retirement vehicles, see Retirement Accounts 101 for a foundational overview.
| Criterion | Roth IRA | Traditional IRA |
|---|---|---|
| Tax treatment of contributions | After-tax (no deduction) | May be pre-tax (deductible) |
| Tax treatment of withdrawals | Tax-free (qualified distributions) | Taxed as ordinary income |
| Income limits to contribute | Yes — phases out at higher incomes | No income limit to contribute |
| Deduction income limits | N/A | Yes — if covered by workplace plan |
| Required Minimum Distributions | None during owner's lifetime | Required starting at age 73 |
| Early withdrawal of contributions | Anytime, no tax or penalty | Taxed and penalized before age 59½ |
| Best tax environment to use | Lower tax rate now than in retirement | Higher tax rate now than in retirement |
Key Rules: Contributions, Limits, and Eligibility
Both account types share the same annual contribution limit established by the IRS, and both allow an additional catch-up contribution for savers aged 50 and older. You can split contributions between both account types in the same year, but your combined total cannot exceed the annual limit.
Roth IRA income limits: Your ability to contribute directly to a Roth IRA phases out above certain modified adjusted gross income (MAGI) thresholds, which the IRS adjusts periodically. Savers above the upper limit cannot make direct Roth contributions, though other strategies — such as a backdoor Roth — exist and carry their own complexity and tax implications.
Traditional IRA deductibility: Anyone with earned income can contribute to a Traditional IRA regardless of how much they earn. However, the tax deduction phases out if you (or your spouse) are covered by a workplace plan and your income exceeds IRS thresholds. Non-deductible Traditional IRA contributions are still allowed and still grow tax-deferred.
$7,000
2024 annual IRA contribution limit
The IRS set the combined IRA contribution limit at $7,000 for 2024, with an additional $1,000 catch-up allowed for savers aged 50 and older.
Age 73
Traditional IRA RMD start age
Under the SECURE 2.0 Act, Traditional IRA owners must begin required minimum distributions at age 73, up from the prior threshold of 72.
Required Minimum Distributions (RMDs): Traditional IRA owners must begin taking RMDs at age 73 under current federal rules. Roth IRAs have no RMD requirement during the original owner's lifetime, which can be valuable for those who do not need to draw down assets on a fixed schedule.
The Tax Bracket Question — and Why It Matters Most
Financial educators often frame the Roth vs. Traditional choice as a prediction about your future tax rate. If your tax rate will be higher in retirement than it is today, paying tax now (Roth) is generally the more efficient path. If your rate will be lower in retirement, deferring tax (Traditional) tends to work in your favor.
In practice, predicting future tax rates involves uncertainty — personal income changes, tax law changes, and the composition of your other retirement income all play a role. Many advisers suggest that holding both types of accounts (tax diversification) gives you more flexibility to manage your taxable income strategically in retirement.
If you are still building the financial foundation that makes retirement saving possible, reviewing how your spending is structured can help. See how fixed and variable expenses differ to identify room in your budget for consistent contributions.
And if you are newer to the concept of putting money to work over time, understanding the difference between saving and investing is a useful starting point before committing to either account type.
