Roth or Traditional IRA: What to Compare in 2026
Choosing between a Roth IRA and a traditional IRA starts with a tax question: Would you rather pay income tax on the money now or potentially pay it when you withdraw it? But that shortcut misses important details. Your income, workplace retirement coverage and need for access to savings can change which account makes sense. For 2026, the IRS has raised both the annual IRA contribution limit and several income thresholds, making last year's figures the wrong guide for this year's deposits.
The most important distinction is that permission to contribute to a traditional IRA is not the same as permission to deduct the contribution. A higher earner may be allowed to fund a traditional IRA while receiving no immediate tax break. Roth IRAs work differently: Contributions are never deductible, and income can prevent you from contributing directly.
1. Start with the verified 2026 contribution limits
For tax year 2026, the IRS limits combined contributions to traditional and Roth IRAs to $7,500, or $8,600 if you are 50 or older by year-end. The additional catch-up contribution is $1,100. These are individual limits, not limits for each account. Opening several IRAs does not multiply your allowance, and splitting contributions between Roth and traditional accounts does not increase it.
Your contribution also generally cannot exceed your taxable compensation for the year. Wages, salaries and net self-employment earnings typically count; investment income generally does not. There is no upper age limit for contributing if you otherwise qualify. Married couples filing jointly may use the spousal IRA rules when one spouse has little or no compensation, provided their combined eligible compensation supports the contributions.
Keep the tax year straight when funding an account this spring. As of March 17, most taxpayers can still make a 2025 IRA contribution until April 15, 2026. The 2025 limits are $7,000, or $8,000 at age 50 or older. Tell the custodian which year the deposit covers; a tax-filing extension generally does not extend the contribution deadline.
| Contribution rule | 2026 amount or treatment |
|---|---|
| Under age 50 | $7,500 combined across traditional and Roth IRAs |
| Age 50 or older by year-end | $8,600 combined, including a $1,100 catch-up |
| Compensation requirement | Generally limited to eligible compensation, with spousal IRA rules available |
| Workplace plan participation | Does not itself reduce the IRA contribution limit |
2. Compare the tax break, not just the account label
A deductible traditional IRA contribution can reduce federal taxable income for the contribution year. Investments generally grow tax-deferred, and withdrawals attributable to deducted contributions and earnings generally count as ordinary income. A deduction is not a dollar-for-dollar tax credit: Its value depends on your tax situation. A fully deductible $1,000 contribution that reduces income otherwise taxed at 22% would generally save $220 in federal income tax.
A Roth IRA provides no upfront deduction. Instead, qualified withdrawals are federally tax-free. That can make a Roth attractive when your current marginal tax rate is relatively low or you want a source of retirement income that generally does not increase taxable income. Traditional treatment may be more appealing when you can deduct the contribution at a higher rate than you expect to pay on withdrawals.
Neither choice guarantees the better outcome because future income and tax laws are uncertain. Compare current and expected future marginal rates, including state taxes. For a fair comparison, also consider whether you would save or spend the tax savings from a deductible traditional contribution. A nondeductible traditional contribution requires a separate analysis.
3. Check whether you can contribute directly to a Roth
Roth eligibility depends on filing status and modified adjusted gross income, or MAGI, calculated under the IRA rules. MAGI is not necessarily your salary or the adjusted gross income shown on your return. For 2026, direct Roth contributions begin phasing out at $153,000 for single and head-of-household filers and disappear at $168,000. For married couples filing jointly, the range is $242,000 to $252,000.
Below the applicable range, you can generally contribute up to your otherwise permitted limit. Within it, the allowed amount is reduced; at or above the upper threshold, no direct contribution is allowed. Married people filing separately who lived with their spouse at any time during the year generally face a $0-to-$10,000 phaseout. Those who lived apart for the entire year generally use the single-filer range.
Estimate carefully if bonuses, investment gains or self-employment income could push you across a threshold. Excess contributions can trigger a 6% annual excise tax while they remain uncorrected. Ask the custodian about the proper correction procedure rather than simply withdrawing an arbitrary amount.
- Use the IRS Roth IRA worksheet to calculate a reduced contribution.
- Recheck eligibility before filing if your final income differs from your estimate.
- Workplace retirement coverage does not, by itself, disqualify you from a Roth IRA.
4. Separate traditional IRA contribution eligibility from deductibility
Traditional IRAs generally have no income ceiling on contributions, provided you meet the compensation and annual-limit rules. The deduction is a separate question. If neither you nor your spouse is covered by a retirement plan at work, your otherwise allowable traditional IRA contribution is generally fully deductible regardless of income. When workplace coverage applies, filing status and MAGI determine whether the deduction is full, partial or unavailable.
The 2026 deduction phaseouts below apply to common filing situations. Below a listed range, the deduction is generally full; within it, partial; at or above its upper endpoint, unavailable. Being covered by a workplace plan is not always the same as personally choosing to contribute. Employer contributions and pension participation can matter. Check the retirement-plan box on Form W-2 and confirm uncertain coverage with your employer.
For married filing separately, the $0-to-$10,000 range generally applies when workplace coverage is relevant and you lived together during the year. Living apart all year can change the treatment. Do not substitute the Roth income test for the deduction test: They answer different questions, even when some thresholds happen to match.
| 2026 deduction situation | MAGI phaseout range |
|---|---|
| Single or head of household; contributor covered at work | $81,000–$91,000 |
| Married filing jointly; contributor covered at work | $129,000–$149,000 |
| Married filing jointly; contributor not covered, spouse covered | $242,000–$252,000 |
| Married filing separately; workplace coverage applies and spouses lived together | $0–$10,000 |
5. Understand what a nondeductible contribution does
If income eliminates your traditional IRA deduction, the contribution can still be legal. It creates after-tax basis: Money that should not be taxed again when distributed. Earnings remain tax-deferred rather than becoming automatically tax-free. You generally must file Form 8606 to report nondeductible contributions and preserve the records needed to calculate taxable distributions later.
You generally cannot isolate after-tax dollars by putting them in a separate traditional IRA. The distribution and conversion calculations typically aggregate your traditional, SEP and SIMPLE IRAs. That pro rata rule matters for a backdoor Roth strategy, in which someone makes a nondeductible traditional IRA contribution and then converts money to a Roth. A large existing pretax IRA balance can make much of the conversion taxable.
Roth conversions do not have the direct-contribution income ceiling, but they are not an extra contribution allowance or a guaranteed tax-free workaround. Pretax amounts converted generally create taxable income in the conversion year. Before proceeding, calculate the impact using all relevant IRA balances, including year-end balances, and determine how you would pay any tax.
- Retain Forms 8606 and supporting basis records across custodial transfers.
- Review traditional, SEP and SIMPLE balances before planning a conversion.
- Do not assume an unavailable deduction makes a contribution prohibited.
6. Compare withdrawal rules before you need the money
Traditional IRA withdrawals are generally taxable except for the portion representing after-tax basis. Before age 59½, the taxable portion also generally faces a 10% additional tax unless an exception applies. An exception to that additional tax usually does not erase the ordinary income tax. Education expenses and qualifying first-home purchases are examples with specific conditions and limits, not blanket permission for tax-free withdrawals.
Roth IRAs offer more flexibility because IRS ordering rules generally treat regular contributions as coming out first. Those contributions can ordinarily be withdrawn without income tax or penalty. Earnings receive tax-free treatment only when the distribution is qualified: Generally, the five-tax-year holding requirement must be satisfied and you must be at least 59½, disabled, deceased, or using the qualifying first-home provision, subject to its lifetime limit.
Conversions have separate five-year rules that can produce an early-distribution penalty, so do not treat every Roth dollar like a regular contribution. Traditional IRA owners also face required minimum distributions, generally beginning at 73 for people born in 1951 through 1959 and 75 for those born in 1960 or later. Roth IRA owners have no lifetime required minimum distributions; beneficiaries have separate rules.
7. Make the choice using your actual tax situation
Start with eligibility, then compare the tax outcomes. Someone eligible for both a full traditional deduction and a full Roth contribution has a genuine pay-now-or-pay-later decision. Someone above the traditional deduction range but within the Roth contribution range faces a different choice: A Roth may offer a clearer tax benefit than a nondeductible traditional IRA.
You do not have to put the entire annual contribution into one type. Splitting it can provide tax diversification, as long as the combined contribution stays within your limit and each portion satisfies its rules. Account fees, investment choices and service also matter, but distinguish those custodian features from the tax rules governing the account.
- Confirm compensation, filing status and workplace coverage before depositing.
- Estimate 2026 MAGI separately for Roth eligibility and traditional deductibility.
- Compare tax rates, withdrawal needs and existing pretax IRA balances.
Verify current IRS limits and account terms, and consult a qualified tax professional about eligibility, deductions, conversions and withdrawals in your circumstances.
