Where Does Form 5498 Go on Your Tax Return? Lines 4a, 4b, 8606

Form 5498 doesn’t go anywhere on your tax return. It’s an informational form your IRA custodian sends to you and the IRS to confirm contributions, rollovers, conversions, and year-end account values. You never attach it to Form 1040 or enter it as its own line item. Instead, you use the numbers on Form 5498 to complete the forms that do affect your tax: Schedule 1 for the IRA deduction, Form 8606 for nondeductible contributions and conversions, Form 5329 for excess contributions, and Lines 4a and 4b of Form 1040 for rollovers and conversions.

Getting those entries right matters, because the IRS cross-references what you claim against what your custodian reported on Form 5498.

What Each Box on Form 5498 Is Telling You

Your custodian files a Form 5498 for every Traditional, Roth, SEP, or SIMPLE IRA it holds for you.¹ The boxes you’ll actually need when preparing your return are:²

Box 1: Traditional IRA contributions for the tax year, including any made through the April 15 deadline.
Box 2: Rollover contributions received during the calendar year.
Box 3: Amounts converted from a Traditional (or Traditional SIMPLE) IRA to a Roth IRA.
Box 5: Fair market value of the account as of December 31.
Box 8: SEP IRA contributions made during the calendar year.
Box 9: SIMPLE IRA contributions, including salary deferrals.
Box 10: Roth IRA contributions for the tax year, including those made through April 15.
Box 11: A checkbox indicating an RMD is due for the following year.

Traditional IRA Contributions: Schedule 1 or Form 8606

The number in Box 1 is your total Traditional IRA contribution. Where it lands on your return depends on whether it’s deductible.

If you qualify for the deduction, the deductible amount goes on Schedule 1 (Additional Income and Adjustments to Income), Line 20. The Schedule 1 total then flows to Form 1040, Line 10, reducing your adjusted gross income. This is an above-the-line adjustment, so it works whether you itemize or take the standard deduction. The 2026 contribution limit is $7,500, or $8,600 if you’re 50 or older, and the deduction phases out at higher incomes if you or your spouse are covered by a workplace retirement plan.³⁴

If the contribution is nondeductible, it goes on Form 8606, Line 1.⁵ Filing Form 8606 for every year of nondeductible contributions is not optional. It’s the only record establishing your basis, and without it the IRS will treat the money as never-taxed when you withdraw it, and tax it again.⁶

If your contribution was partly deductible and partly not, split it: the deductible piece goes to Schedule 1, the nondeductible piece to Form 8606.

Roth IRA Contributions: Nowhere on This Year’s Return

Roth contributions in Box 10 don’t get reported on Form 1040 or any schedule for the year you make them. They’re made with after-tax money, so there’s no deduction and no line to fill in. You also don’t file Form 8606 just because you made a Roth contribution.⁶

Form 8606 comes back into play when you take a Roth distribution. Part III of that form, at Line 22, asks for your total Roth contribution basis across all years.⁷ That’s why you should keep every Form 5498 showing Roth contributions, even though nothing on it touches your current-year return.

Rollovers: Form 1040 Lines 4a and 4b

Box 2 confirms that a rollover contribution landed in your IRA. The reporting happens on Form 1040: the full distribution amount goes on Line 4a, and the taxable portion on Line 4b.⁸ For a properly completed rollover, Line 4b is usually zero, and you write “Rollover” next to the entry.

The rollover doesn’t count against your annual contribution limit. The IRS uses Form 5498 to match the money arriving at the new custodian against the Form 1099-R issued by the old one. If you missed the 60-day window or violated the one-rollover-per-12-months rule, what you called a rollover may become a taxable distribution.

Roth Conversions: 1040 Lines 4a, 4b, and Form 8606 Part II

Box 3 reports the dollar amount converted from a Traditional IRA to a Roth IRA. A conversion is a taxable event, not a contribution. Report it on Form 1040, Lines 4a and 4b, using the Form 1099-R your custodian issues for the conversion, and complete Part II of Form 8606 to work out how much of the conversion is actually taxable.⁵⁶

If you have other Traditional IRA balances holding pretax money, the pro-rata rule applies and part of the conversion will be taxable even when the underlying contribution was nondeductible. That calculation lives on Form 8606.

SEP and SIMPLE IRA Contributions

Box 8 shows SEP contributions and Box 9 shows SIMPLE contributions.² Where they go depends on who made them.

If you’re self-employed and put SEP money into your own IRA, you deduct it on Schedule 1 in the self-employed retirement plan deduction line, which is separate from the personal IRA deduction line. If your employer made the SEP or SIMPLE contribution, it usually doesn’t appear on your Form 1040 at all; the employer takes the deduction as a business expense. SIMPLE IRA salary deferrals are already excluded from your taxable wages on Form W-2, so nothing extra goes on your return.⁹ Box 9 exists so the IRS can verify the deferral amount independently.

Excess Contributions: Form 5329

Because Form 5498 tells the IRS exactly how much you contributed, it’s how overages get flagged. Contributions above the annual limit are subject to a 6% excise tax for each year the excess stays in the account.¹⁰

You can avoid the penalty by withdrawing the excess plus its earnings before your filing deadline, including extensions. If you don’t, report the excess on Form 5329: Part III for Traditional IRAs and Part IV for Roth IRAs. The resulting tax carries to Schedule 2, Line 8 of Form 1040.¹¹

What the RMD Boxes Signal

Box 11, when checked, means an RMD is required from the account for the following year. Custodians must check it starting in the year the account holder turns 73, even though the first RMD can be deferred to April 1 of the year after that.¹² Box 5’s December 31 fair market value is the figure used to calculate that RMD.

Nothing about the RMD flags goes on your current return. When you actually take the distribution the following year, your custodian issues a Form 1099-R, and you report the withdrawal on Form 1040, Lines 4a and 4b.

Why the Form Arrives After You File

Custodians have until May 31 of the following year to send Form 5498, because the form has to capture contributions made all the way through April 15.¹³ Most people file their return before Form 5498 shows up.

That’s fine. Use your own records or your custodian’s year-end statement for the numbers you report. When the 5498 arrives, compare it against what you filed. If the numbers don’t match, you may need to file Form 1040-X to correct the return.

Keep Every Copy

Form 5498 never gets attached to a tax return, but it’s one of the most useful documents in your long-term tax file. It documents your contribution history year by year, tracks the basis you’ll need for Roth or nondeductible distributions decades from now, and confirms rollovers the IRS may question. If a withdrawal is ever challenged as taxable when it shouldn’t be, your stack of Form 5498s is the first thing to pull.
