Where Do You Report IRA Contributions on Your Tax Return?

Where you report an IRA contribution on your tax return depends on which kind you made. A deductible Traditional IRA contribution goes on Schedule 1 (Form 1040), Line 20. A nondeductible Traditional IRA contribution is reported on Form 8606, filed with your Form 1040. A Roth IRA contribution isn’t reported on your tax return at all in the year you make it.

Deductible Traditional IRA: Schedule 1, Line 20

If your Traditional IRA contribution qualifies as deductible, you enter it on Schedule 1, “Additional Income and Adjustments to Income,” which attaches to Form 1040.¹ The specific line is Line 20, labeled “IRA deduction.”² That figure carries to the adjustments section of Form 1040 and reduces your adjusted gross income. Because it moves AGI rather than only taxable income, it can also affect your eligibility for other credits and deductions that use AGI thresholds.

Whether your contribution is actually deductible depends on your modified adjusted gross income and whether you or your spouse is covered by an employer retirement plan. If neither spouse is covered, the contribution is fully deductible regardless of income. When a workplace plan is in the picture, deductibility phases out across these 2026 MAGI ranges:³

Single or head of household, covered by a workplace plan: $81,000 to $91,000
Married filing jointly, contributing spouse covered: $129,000 to $149,000
Married filing jointly, contributor not covered but spouse is: $242,000 to $252,000
Married filing separately, covered by a workplace plan: $0 to $10,000

Below the low end, the full contribution is deductible. Above the high end, none of it is. Between the two, you get a partial deduction; the worksheets in the Form 1040 instructions and Publication 590-A calculate the exact figure.

Nondeductible Traditional IRA: Form 8606

If your income puts you past the phase-out, or you simply choose not to deduct the contribution, it becomes nondeductible. You’ve contributed money that was already taxed, and that creates “basis” in the account. Form 8606, Nondeductible IRAs, is how you tell the IRS about it. The current-year nondeductible amount goes in Part I, added to any basis carried from prior years.⁴ The form files with your Form 1040.

Failing to file Form 8606 when required triggers a $50 penalty, and it also leaves you without the record you’ll need later.⁵ Without a documented basis, the IRS has no way to know which dollars in your IRA have already been taxed, and you can end up paying tax on the same money twice when you eventually withdraw. Every distribution from a Traditional IRA is treated as a proportional mix of taxable and nondeductible dollars under the pro-rata rule, and that calculation runs off the cumulative basis you’ve reported on Form 8606.

Roth IRA: Nothing to Report at Contribution

Roth IRA contributions do not appear anywhere on your tax return in the year you make them. There is no line on Schedule 1, no entry on Form 1040, and the instructions for Form 8606 explicitly state that you don’t need to file that form solely to report regular Roth contributions.⁵ Roth contributions are made with after-tax dollars and are never deductible, so there is nothing for the return to capture.

That doesn’t mean you can skip record-keeping. Keep your own running total of every Roth contribution you make. When you eventually take money out, Form 8606 Part III uses that total to determine whether the withdrawal is taxable, and reconstructing years of contribution history after the fact is far harder than tracking it as you go.

Your ability to contribute to a Roth in the first place depends on MAGI. For 2026 the ranges are:³

Single or head of household: full contribution below $153,000, reduced from $153,000 to $168,000, none at $168,000 or above
Married filing jointly: full contribution below $242,000, reduced from $242,000 to $252,000, none at $252,000 or above
Married filing separately (lived with spouse at any point in the year): reduced below $10,000, none at $10,000 or above

Backdoor Roth: Both Parts of Form 8606

People whose income rules out a direct Roth contribution often contribute to a nondeductible Traditional IRA and then convert it. Both steps touch Form 8606 in the same year. The nondeductible Traditional contribution goes into Part I, establishing basis. The conversion goes into Part II, which calculates how much of the converted amount is taxable.⁵ The converted amount then appears on Form 1040 Line 4a as the total distribution, with Line 4b showing the taxable portion.

If the only money in your Traditional IRA is the nondeductible contribution you just made, the taxable amount on conversion is essentially zero. If you have other Traditional IRA balances from deductible contributions or rollovers, the pro-rata rule applies to the conversion too, and a portion of the converted amount will be taxable in proportion to your total Traditional IRA balance.

Form 5498 Is Not Something You File

Your IRA custodian sends Form 5498 to both you and the IRS, confirming how much you contributed for the tax year.⁶ It often arrives in late May because custodians have until May 31 to submit it, well after most people have filed. You do not attach Form 5498 to your return; it’s a record-keeping document. Deciding whether your contribution is deductible, nondeductible, or a Roth contribution is your responsibility.

Contribution Deadline and Which Year It Counts For

You have until the tax filing deadline, typically April 15 of the following year, to make an IRA contribution for the prior tax year.⁷ A contribution made in February 2027 can be applied to either 2026 or 2027. Your custodian will ask which year to designate, and that answer determines which return the contribution belongs on.

The combined limit for 2026 across all Traditional and Roth IRAs is $7,500, with an additional $1,100 catch-up for those 50 or older, for a total of $8,600.³

If You Contributed Too Much: Form 5329

Excess contributions, whether you went over the annual limit or contributed to a Roth despite exceeding the income threshold, are hit with a 6% excise tax for every year the excess stays in the account.⁸ That tax is reported on Form 5329 and carried to Schedule 2 of your return.⁹

You can avoid the penalty by withdrawing the excess plus any earnings before your tax filing deadline, including extensions.⁷ When corrected in time, the IRS treats the contribution as never made, and it doesn’t appear on Form 1040, Form 8606, or Form 5329.

Saver’s Credit on Form 8880

Low- and moderate-income contributors may also qualify for the Retirement Savings Contributions Credit, the Saver’s Credit. It’s separate from the Traditional IRA deduction, and eligible filers can claim both. The credit is calculated on Form 8880 and carried to Form 1040 as a nonrefundable credit that reduces tax liability directly.¹⁰

The credit is 50%, 20%, or 10% of your contribution, up to $2,000 per person or $4,000 for married couples filing jointly, depending on AGI and filing status.¹¹ The 2026 AGI thresholds are:¹²

50% credit: AGI up to $48,500 (married filing jointly), $36,375 (head of household), or $24,250 (single and other filers)
20% credit: AGI up to $52,500 (married filing jointly), $39,375 (head of household), or $26,250 (single and other filers)
10% credit: AGI up to $80,500 (married filing jointly), $60,375 (head of household), or $40,250 (single and other filers)

Above those thresholds, the credit is zero. Because it’s nonrefundable, it can reduce your tax to zero but won’t produce a refund on its own.
