A Roth IRA and a Traditional IRA share the same annual contribution cap but flip the tax treatment: a Traditional IRA generally lets you deduct contributions now and taxes withdrawals in retirement, while a Roth IRA takes after-tax dollars now and pays out tax-free later. For 2026, both accounts allow $7,500 in contributions ($8,600 if you’re 50 or older).1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500 The rest of the choice comes down to your current versus future tax rate, income eligibility, and how much flexibility you want before retirement.

Contribution Limits and Who Can Contribute
The IRS raised the annual IRA contribution ceiling to $7,500 for 2026, up from $7,000. If you’re 50 or older, an extra $1,100 catch-up brings your total to $8,600.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500 The cap is combined across all your IRAs. Put $5,000 in a Roth and you have $2,500 left for a Traditional in the same year.
You need earned income to contribute. Wages, salaries, tips, bonuses, and net self-employment income count. Investment income, rental income, and pension payments don’t.2Internal Revenue Service. Topic No. 451, Individual Retirement Arrangements (IRAs) Your contribution can’t exceed what you earned, so someone with $3,000 of earned income can only contribute $3,000 regardless of the cap.
A non-working spouse can still fund an IRA if the couple files jointly and the working spouse earns enough to cover both contributions. Each spouse can put in up to their own limit as long as the combined total doesn’t exceed the joint taxable compensation.3Internal Revenue Service. Retirement Topics – IRA Contribution Limits
Contributing more than allowed triggers a 6% excise tax on the excess for every year it stays in the account. You can fix it by pulling the excess (plus any earnings it produced) before your tax-filing deadline, including extensions.3Internal Revenue Service. Retirement Topics – IRA Contribution Limits
How the Tax Treatment Differs
The whole comparison turns on when you pay tax. A Traditional IRA gives you the break now; a Roth IRA gives you the break later. Everything else flows from that.
Traditional IRA
Contributions may be fully or partially deductible depending on your income and whether you or your spouse is covered by a workplace retirement plan. When the deduction applies, your taxable income drops dollar-for-dollar. A person in the 22% bracket deducting a $7,500 contribution shaves $1,650 off that year’s tax bill.4Internal Revenue Service. Publication 590-A – Contributions to Individual Retirement Arrangements (IRAs)
Investments grow without annual tax on dividends or gains. You pay ordinary income tax on the full amount when you withdraw. If income limits reduced or eliminated your deduction, the after-tax portion becomes a nondeductible contribution, tracked on Form 8606, and only the earnings are taxed when withdrawn.5Internal Revenue Service. 2025 Instructions for Form 8606
Roth IRA
Every dollar going in has already been taxed. No deduction. In exchange, qualified withdrawals of contributions and earnings come out completely tax-free.6Internal Revenue Service. Roth IRAs A withdrawal counts as qualified once you’ve held any Roth IRA for at least five tax years and are 59½ or older (or meet another qualifying event like disability or death).
There’s a practical bonus that often gets overlooked. You can pull out your Roth contributions at any time, for any reason, with no tax or penalty. The IRS applies a fixed order to Roth withdrawals: contributions first, then conversions, then earnings. As long as you stay within what you’ve put in, you owe nothing.7Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs)
Which One Wins on Taxes
If you expect a lower tax rate in retirement than you’re paying now, the Traditional IRA usually comes out ahead. You deduct at a high rate and pay at a lower one later. If you expect your rate to hold steady or climb, the Roth tends to win because you lock in today’s rate on contributions and pay nothing on decades of growth. Workers early in their careers, still in lower brackets, often find the Roth especially valuable for that reason.
Income Limits for 2026
Both accounts have income restrictions, but they act differently. Traditional IRA income limits govern how much of your contribution you can deduct. Roth IRA income limits govern whether you can contribute directly at all.
Traditional IRA Deduction Phase-Outs
If neither you nor your spouse participates in a workplace retirement plan, Traditional IRA contributions are fully deductible no matter your income. The phase-outs below only apply when you or your spouse has access to a plan like a 401(k).
- Single filer covered by a workplace plan: full deduction with MAGI at or below $81,000, partial between $81,000 and $91,000, none at $91,000 or above.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500
- Married filing jointly, contributing spouse covered: full at or below $129,000, partial between $129,000 and $149,000, none at $149,000 or above.
- Married filing jointly, only the other spouse covered: full at or below $242,000, partial between $242,000 and $252,000, none at $252,000 or above.
Even above these limits, you can still contribute to a Traditional IRA. You just can’t deduct it. The nondeductible contribution grows tax-deferred, and only the earnings get taxed on withdrawal. Report these contributions on Form 8606.5Internal Revenue Service. 2025 Instructions for Form 8606
Roth IRA Contribution Phase-Outs
Roth income limits are a hard cutoff. Once your MAGI clears the upper threshold, direct Roth contributions aren’t allowed at all.
- Single or head of household: full contribution below $153,000, reduced between $153,000 and $168,000, none at $168,000 or above.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500
- Married filing jointly: full below $242,000, reduced between $242,000 and $252,000, none at $252,000 or above.
- Married filing separately while living with a spouse: reduced below $10,000, none at $10,000 or above.
Getting Your Money Out
Both accounts impose a 10% additional tax on money taken before age 59½, but the penalty lands differently.8Internal Revenue Service. Retirement Plans FAQs Regarding IRAs Distributions (Withdrawals)
With a Traditional IRA, an early withdrawal faces ordinary income tax and the 10% penalty on the full amount, assuming your contributions were deductible. There’s no separation between contributions and earnings because none of it has ever been taxed.
With a Roth IRA, the ordering rules soften the blow. Contributions come out first and have already been taxed, so the 10% penalty only appears once you dip into earnings. Someone who has contributed $30,000 over the years can withdraw up to $30,000 at any age without owing anything.7Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs)
The 10% penalty has a long list of exceptions covering situations like a first home purchase (up to $10,000), qualifying higher education expenses, permanent disability, high unreimbursed medical costs, birth or adoption expenses (up to $5,000 per child), and health insurance premiums while unemployed.9Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Exceptions remove the 10%, but they generally don’t eliminate income tax on a Traditional IRA distribution.
Required Minimum Distributions
A Traditional IRA eventually forces you to start withdrawing whether you want to or not. If you were born between 1951 and 1959, RMDs begin the year you turn 73. If you were born in 1960 or later, they begin at 75.10Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) Your first RMD is due by April 1 of the year after you reach the applicable age, and every one after that is due by December 31.
Missing an RMD costs you 25% of the shortfall. Catch it and correct it within roughly two years and the penalty drops to 10%.11Office of the Law Revision Counsel. 26 USC 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans
A Roth IRA has no RMDs during the original owner’s lifetime. The statute explicitly exempts Roth accounts from the distribution requirements that apply to Traditional IRAs.12Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs The account can keep growing tax-free for as long as you live. For anyone who doesn’t need the money to cover living expenses, this alone can tip the choice toward a Roth.
Backdoor Roth for High Earners
If your income shuts you out of direct Roth contributions, a Roth conversion is the way in. A conversion moves funds from a Traditional IRA (or other pre-tax retirement account) into a Roth IRA. You pay income tax on the converted amount that year, and from then on the money follows Roth rules. There’s no income limit on conversions.13Internal Revenue Service. Retirement Plans FAQs Regarding IRAs
The backdoor Roth is a two-step version of that. First, contribute to a Traditional IRA on a nondeductible basis (anyone can, regardless of income). Second, convert those funds to a Roth IRA, usually within a few days. Because the contribution wasn’t deducted, you’ve already paid tax on it, so the conversion itself triggers little or no additional tax. Both steps get reported on Form 8606.5Internal Revenue Service. 2025 Instructions for Form 8606
The strategy gets messy if you already hold pre-tax money in any Traditional, SEP, or SIMPLE IRA. The pro-rata rule treats all your non-Roth IRA balances as one pool and calculates the taxable portion of any conversion proportionally. With $90,000 in pre-tax Traditional IRA funds and a $7,500 nondeductible contribution, only about 7.7% of a conversion would be tax-free; the rest would be taxable. Rolling pre-tax IRA balances into a workplace 401(k) before converting is the usual workaround.
How to Make the Call
Tax brackets dominate the conversation, but a few other factors carry real weight. If you want the option to reach your contributions before retirement without penalty, the Roth is the only account that reliably allows it. If you want to avoid forced withdrawals in your 70s, the Roth wins again. If you’re trying to lower your current-year tax bill or reduce AGI to qualify for other credits and deductions, the Traditional IRA’s upfront break is more immediately useful.
You don’t have to pick one for life. You can lean on Traditional contributions during high-earning years and shift to Roth during lower-income stretches. You can split a single year’s contribution between the two as long as the combined total stays under the annual cap.3Internal Revenue Service. Retirement Topics – IRA Contribution Limits The most expensive mistake is spending so long debating the choice that you delay contributing at all. Either account, funded consistently, beats a taxable brokerage account for long-term retirement savings.
