Whether you track income with a pay stub generator or rely on employer payroll software, this guide explains what Form 5498-SA reports, what each box means, and the exact steps to take when you receive it.

What Is Form 5498-SA?

IRS Form 5498-SA reports annual contributions to your HSA, Archer Medical Savings Account, or Medicare Advantage MSA. You may also see it written as 5498SA on bank and brokerage portals. Your account trustee (not you) files it with the IRS and sends you a copy by May 31. You don't need to file it with your tax return.

If you're wondering, "What is a 5498 SA tax form?" the short answer is that it confirms how much was deposited into your medical savings account for the year. Receiving this 5498-SA tax form doesn't mean you owe taxes or need to act before your filing deadline.

Your account trustee, typically a bank or credit union, handles the IRS filing. Your copy is for record-keeping. Keep it with your tax documents. If the IRS ever questions your HSA contributions, this form is your proof.

What Accounts Does Form 5498-SA Cover?

Form 5498-SA applies to three types of medical savings accounts. The most common is a health savings account HSA, but it also covers Archer MSA and Medicare Advantage MSA plans.

Health Savings Account (HSA)

Available to anyone enrolled in a qualifying high-deductible health plan (HDHP). Both employees and employers can contribute. For 2026, the IRS contribution limits are $4,300 for self-only and $8,550 for family coverage, with a $1,000 catch-up for those 55 and older.

If you enrolled in an HDHP mid-year but were covered on December 1, the last-month rule lets you contribute the full annual limit. Your 5498 HSA form records these totals each year in Box 2.

Archer Medical Savings Account

Limited to the self-employed and companies with 50 or fewer employees. Only the employer or the employee, not both, can contribute in a given year.

Medicare Advantage MSA

Open to Medicare-eligible individuals. Only Medicare makes contributions. Neither the employer nor the employee can add funds.

When Will You Receive Form 5498-SA?

You'll receive Form 5498-SA by May 31 each year, after the April 15 tax filing deadline. The delayed timing is intentional. Contributions made between January 1 and April 15 can still count for the prior tax year. So, the form can't be finalized until that window closes.

For example, contributions made through April 15, 2026, can apply to your 2025 HSA. Your trustee must provide this 5498 SA tax form by May 31, 2026.

Your employer's HSA contributions are also on Form W-2, Box 12, Code W. Cross-check that figure against Box 2 on your 5498 SA form when it arrives.

What Each Box on Form 5498-SA Means

Employer note: Cross-check Box 2 on Form 5498-SA against Box 12, Code W on your employees' W-2 forms. The HSA 5498 totals and W-2 figures should match. Discrepancies often occur when employees make post-tax contributions between January and April. Contact your payroll provider (ADP, Gusto, etc.) to reconcile before issuing corrected forms.

Form 5498-SA vs. Form 1099-SA: Key Differences

5498-SA vs 1099-SA: these two forms track opposite sides of your HSA activity.

The timing matters. Form 1099-SA arrives in January. Use it to complete Form 8889 when you file. Form 5498-SA arrives in May, after the deadline. At that point, use it to verify your contribution records, not for filing. Together, 1099-SA and 5498-SA give you a complete picture of your account activity for the year.

What Do You Do With Form 5498-SA?

You don't file Form 5498-SA with your tax return. When you receive it, verify Box 2 against your contribution records and Box 5 against your December 31 balance. Both should also align with Box 12, Code W on your W-2. Then file this 5498-SA form with your tax records in case of an IRS audit.

Reading your HSA tax form 5498 is straightforward once you know what each number represents. Run this three-step check when your Form 5498 SA arrives:

1. Verify Box 2: Does the total match your payroll deductions plus any direct contributions?
2. Verify Box 5: Does the fair market value match your December 31 account statement?
3. Cross-Check Your W-2: Employer HSA contributions in Box 12, Code W should align with Box 2.

If you're self-employed and contributed after-tax dollars to your HSA, you can claim a tax deduction on Form 8889. Form 5498-SA confirms the contribution total to include.
