When to Contribute to an IRA: Deadlines, Limits, and Eligibility

For any given tax year, you have until that year’s federal tax filing deadline to fund your IRA. The IRA contribution deadline for the 2025 tax year is April 15, 2026.¹ For the 2026 tax year, you can put in up to $7,500 across your Traditional and Roth IRAs combined, plus a $1,100 catch-up if you’re 50 or older.² The caps are only part of the picture; your earned income, filing status, and workplace retirement coverage all shape what you can actually contribute or deduct.

The April 15 Deadline

Federal law ties the IRA contribution deadline to the due date for filing your income tax return, not including extensions.³ For most people, that’s April 15 of the year after the tax year. April 15, 2026 falls on a Wednesday with no conflicting federal holidays, so the 2025 contribution deadline is simply April 15, 2026.¹ The same date applies to Traditional and Roth IRAs, whether you owe tax or expect a refund.

Filing Form 4868 for a six-month extension does not extend the IRA deadline. That extension covers paperwork only.⁴ Any deposit made after April 15 automatically counts toward the current year. And unused IRA contribution room doesn’t carry forward. Miss the deadline and that year’s space is gone.

One narrow exception: military personnel serving in a designated combat zone get their filing and contribution deadlines pushed out for the period of service plus at least 180 days.⁵

2026 Contribution Limits

The IRS adjusts IRA limits annually for inflation. For 2026:

Under 50: $7,500 total across all your Traditional and Roth IRAs combined
50 or older: $8,600 ($7,500 plus a $1,100 catch-up)

Those limits are up from $7,000 and $8,000 in 2024 and 2025.⁶ The cap covers the total across all your IRAs. Put $5,000 into a Traditional IRA and you have $2,500 left for a Roth (or $3,600 with the catch-up).

There’s also a floor: your contribution can’t exceed your taxable compensation for the year. If you earned $4,000 from a part-time job, $4,000 is your personal maximum regardless of the IRS cap.⁶

Who Qualifies to Contribute

You need taxable compensation to contribute. That covers wages, salaries, tips, commissions, bonuses, and net self-employment income.⁷ What doesn’t count: dividends, interest, rental income, pensions, and Social Security benefits. If those are your only income sources, you can’t contribute on your own.

Nontaxable combat pay is a useful carve-out. It counts as earned income for IRA purposes even though it’s excluded from taxable income, so deployed service members can still contribute based on combat pay.⁸

Self-Employed Math

If you’re self-employed, qualifying compensation is your net earnings from self-employment minus the deductible portion of your self-employment tax.⁹ That deduction is half your self-employment tax and shows up on Schedule 1 of Form 1040. If you also contribute to a SEP or SIMPLE IRA through your business, subtract that too before landing on your plan compensation figure.

Spousal Contributions

Married couples filing jointly have a rule that’s often overlooked. A non-working spouse can contribute to their own IRA based on the working spouse’s income. Each can go up to the full annual limit as long as combined contributions don’t exceed the taxable compensation on the joint return.⁶ If one spouse earns $80,000 and the other has no income, both can still put in $7,500 each (or $8,600 at 50-plus).

No Age Cap

Before 2020, Traditional IRA contributions cut off at age 70½. The SECURE Act repealed that.¹⁰ Anyone with qualifying earned income can now contribute at any age.

How Income Affects Roth Eligibility and Traditional Deductions

Your income determines whether you can contribute to a Roth at all, and whether Traditional IRA contributions are deductible. Both use modified adjusted gross income (MAGI) and filing status to set phase-out ranges.

Roth IRA Phase-Outs

Roth contributions use after-tax dollars, so there’s no deduction to phase out. What phases out is your ability to contribute in the first place. For 2026:²

Single or head of household: full contribution below $153,000 MAGI, reduced from $153,000 to $168,000, none above $168,000
Married filing jointly: full below $242,000, reduced from $242,000 to $252,000, none above $252,000
Married filing separately: reduced from $0 to $10,000, none above $10,000

Contributing over the limit creates an excess contribution subject to a 6% annual penalty until corrected.

Traditional IRA Deduction Phase-Outs

Anyone with earned income can contribute to a Traditional IRA regardless of income. The question is whether the contribution is deductible. If neither you nor your spouse is covered by a workplace retirement plan, the full deduction is available at any income. If a workplace plan is in the mix, deductibility phases out. For 2026:²

Single filer covered by a workplace plan: full deduction below $81,000, partial $81,000 to $91,000, none above $91,000
Married filing jointly, contributor covered: full below $129,000, partial $129,000 to $149,000, none above $149,000
Married filing jointly, contributor not covered but spouse is: full below $242,000, partial $242,000 to $252,000, none above $252,000
Married filing separately, covered by a plan: partial $0 to $10,000, none above $10,000

Even when the deduction fully phases out, you can still make nondeductible Traditional IRA contributions. The gains still grow tax-deferred until withdrawal.

Tagging a January to April Deposit to the Right Year

Between January 1 and April 15, a deposit could count toward either the prior tax year or the current one. Your custodian won’t guess. Brokerages and banks provide a “prior year” or “current year” selection when you contribute during this window. Get it wrong and you can accidentally over-contribute to one year while wasting the other year’s room.

The contribution then shows up on Form 5498, which the custodian files with the IRS and sends to you.¹¹ If the form assigns your contribution to the wrong year, contact the custodian promptly to fix it before the IRS processes the data.

The overlap is also a planning opportunity. A January bonus or February tax refund can go straight into unused prior-year space. Few areas of the tax code offer this kind of retroactive flexibility.

Fixing Excess Contributions

Contributing over your limit triggers a 6% excise tax on the excess for every year it stays in the account.¹² The penalty recurs annually until you fix it, so speed matters.

Withdrawing Before the Deadline

The cleanest fix is pulling out the excess plus its earnings before your tax filing deadline, including extensions. Do that and the IRS treats the excess as if it was never contributed.⁷ You’ll owe income tax on the earnings withdrawn, and if you’re under 59½ the earnings piece also hits the 10% early distribution penalty. But the 6% excise tax goes away, which is the point. Your custodian typically calculates the earnings attributable to the excess when you request the corrective distribution.

The October 15 Window

If you filed your return on time but caught the excess afterward, you have six more months. Withdraw the excess plus earnings by October 15 (for returns due April 15) and file an amended return with “Filed pursuant to section 301.9100-2” at the top.¹³ Include an updated Form 5329 showing the corrective withdrawal.

Miss October 15 and the excess is locked in for that year. You’ll owe the 6% excise tax, reported on Form 5329, and the penalty repeats every year the excess remains.¹² The typical fix at that stage is to absorb the excess into future contribution room, contributing less next year to bring the cumulative total back into compliance.

Recharacterizing

Recharacterization is a separate tool. It redesignates a contribution from one IRA type to the other, useful if your income came in higher than expected and disqualified a Roth contribution, or if you decide you’d rather take the Traditional deduction. The deadline is your tax return’s due date including extensions, and if you filed on time you get an additional six months through October 15 to make the switch and file an amended return.⁷ One boundary worth knowing: recharacterization applies only to contributions. You can no longer recharacterize a Roth conversion back to a Traditional IRA. Conversions are permanent.
