Do I Have to Report Form 5498-SA on My Tax Return?

You do not report Form 5498-SA on your tax return. Your HSA trustee or custodian files it directly with the IRS, and the copy mailed to you is only for your records. The form you actually complete and attach to your Form 1040 is Form 8889, which you fill out from your own records and your W-2. Form 5498-SA covers Health Savings Accounts, Archer MSAs, and Medicare Advantage MSAs, and it exists so the IRS can match what your financial institution reported against what you claim.

What the Form Reports

Form 5498-SA is organized into numbered boxes, each summarizing one piece of contribution or account data for the year:

Box 1: Archer MSA contributions made by the employee or self-employed individual during the calendar year and through April 15 of the following year.
Box 2: Total HSA or Archer MSA contributions made during the calendar year, including any amount contributed that year for the prior year and qualified HSA funding distributions from an IRA.
Box 3: HSA or Archer MSA contributions made between January 1 and April 15 of the following year that are designated for the calendar year shown on the form.
Box 4: Rollover contributions received during the calendar year.
Box 5: The fair market value of the account on December 31, including invested assets.¹
Box 6: A checkbox indicating whether the account is an HSA, Archer MSA, or Medicare Advantage MSA.

Box 3 is the one that trips people up. A contribution made in February 2027 and designated for tax year 2026 shows up in Box 3 on the 2026 form, not on the 2027 form.²

Why the Form Arrives After You File

Most account holders receive Form 5498-SA in May or June, well after the April tax deadline. The reason is baked into HSA rules: you can make contributions for the prior tax year all the way through April 15.³ Your trustee cannot finalize the form until that window closes, because a last-minute contribution would change the totals.

Financial institutions have until May 31 of the following year to file Form 5498-SA with the IRS and send your copy.² Getting the form after you have already filed is normal. The IRS already has the data, and your copy is confirmation.

The Form You Actually File: 8889

Since Form 5498-SA will not arrive in time for tax season, you complete your return from other records. Form 8889 is the form attached to your 1040. You must file it if any of the following applied during the year: someone contributed to your HSA (including your employer), your HSA made a distribution, you failed to maintain eligible coverage during a testing period, or you inherited an HSA.⁴ Receiving HSA distributions triggers a Form 8889 requirement even if you would not otherwise need to file a return.

Form 8889 is where you calculate your HSA deduction, report contributions, and account for distributions.⁵ To fill it out before Form 5498-SA arrives, use year-end pay stubs and your bank or brokerage statements.

Your W-2 and Code W

If your employer contributes to your HSA, or if you make pre-tax contributions through a payroll cafeteria plan, both amounts appear on your W-2 in Box 12 with Code W.⁴ The Code W amount is not just your employer’s share; it includes your own pre-tax payroll deductions. Those combined contributions go on Line 9 of Form 8889. Line 2 is only for contributions you made directly to the HSA outside of payroll.

Form 1099-SA for Distributions

If you spent money from your HSA during the year, your custodian issues Form 1099-SA early in the following year, before the April deadline. It reports total distributions and includes a code for whether they were normal, tied to excess contributions, or triggered by disability or death. You report these on Part II of Form 8889. Any amount not used for qualified medical expenses is added to taxable income, and if you are under age 65 a 20% penalty applies.⁴

Using Form 5498-SA as a Cross-Check

Even though the form is not filed with your return, keep it. When it arrives, compare Box 2 against the total contributions you tracked during the year and the Code W amount on your W-2. Compare Box 3 against contributions you made between January 1 and April 15 that you designated for the prior tax year. If anything does not line up, contact your custodian before the discrepancy turns into an IRS notice.⁶

Three documents should tell the same story: your W-2, your Form 8889, and Form 5498-SA. If Form 8889 used estimated figures and the final Form 5498-SA reveals different numbers, you may need to file an amended return to correct the contribution or deduction amounts.

If Form 5498-SA Shows Excess Contributions

Contributions above the annual limit will not fix themselves. The IRS imposes a 6% excise tax on excess contributions for every year they remain in the account.⁷ The tax compounds annually until you pull the excess out.

To avoid the penalty, withdraw the excess amount plus any earnings it generated by the due date of your return, including extensions. If you already filed without catching it, you have a second chance: withdraw within six months after the original due date (not including extensions) and file an amended return.⁴ The earnings on the withdrawn excess are included in taxable income for the year of the withdrawal.

If the excess stays past those deadlines, you report the 6% excise tax on Form 5329.⁸ It applies every year until the excess is absorbed by unused contribution room in a future year or withdrawn. The common failure pattern: over-contribute, miss it, and pay the 6% penalty two or three years in a row.

A Note on State Returns

Federal tax treatment of HSAs is uniform, but California and New Jersey do not follow it. In those states, HSA contributions are not deductible on the state return, and interest or investment gains inside the account count as taxable state income. Form 5498-SA still is not filed with your state return, but the contribution data on it becomes relevant for calculating state tax liability.
