Form 5498-SA is an information statement from an HSA or certain MSA trustees or custodians reporting contribution and account information. It is different from Form 1099-SA, which reports distributions. For an HSA, compare the form with actual account deposits, contribution-year designations, payroll, and W-2 Code W; do not simply add every box or assume the total is your personal tax deduction.
This guide focuses on reading HSA information. Its box walkthrough and fictional example use the official 2025 Form 5498-SA and 2025 IRS instructions, checked November 9, 2026. Use the form's printed year and corresponding instructions for another year. Archer MSA and Medicare Advantage MSA rules are not interchangeable with HSA rules.
Who sends Form 5498-SA, and what does it establish?
The IRS form overview identifies the trustee or custodian as the filer. An employee does not issue this statement just because an HSA deduction appears on payroll. If you use more than one account provider, review each relevant account's information and any corrected statement.
The statement helps document what the custodian reported. It does not independently decide whether you were eligible to contribute, whether you exceeded your limit across all accounts, or whether a distribution paid qualified medical expenses. Those questions require the applicable tax rules and your supporting records.
What do the boxes on the 2025 form mean?
| Box | What the 2025 form reports | Important check |
|---|---|---|
| 1 | Employee or self-employed person's Archer MSA contributions for 2025 | This is not the HSA contribution box |
| 2 | Total HSA or Archer MSA contributions made during calendar 2025 | Can include deposits made in 2025 for 2024; excludes Box 4 rollovers |
| 3 | HSA or Archer MSA contributions made in 2026 for 2025 | Check the actual prior-year designation |
| 4 | Reportable rollover contributions received during 2025 | Not another ordinary contribution to add to Boxes 2 and 3 |
| 5 | Fair market value at December 31, 2025 | An account value, not a new contribution or annual wage amount |
| 6 | The account type: HSA, Archer MSA, or MA MSA | Apply the rules for the selected type |
The 2025 participant instructions say Boxes 2 and 3 are provided for IRS use. They are useful reconciliation clues, not instructions to enter their sum automatically as a deduction. Read the underlying transactions and follow the return instructions. Also distinguish this form from IRA Form 5498, which has a similar number but reports different accounts.
Why can Box 2 differ from contributions for the tax year?
Calendar-year timing and contribution-year designation can differ. The 2025 filing instructions explicitly include in Box 2 contributions made during 2025 for 2024, while Box 3 reports contributions made during 2026 for 2025.
Assume $300 deposited in early 2025 was properly designated for 2024; $2,200 deposited during 2025 was for 2025; and $400 deposited in February 2026 was properly designated for 2025. Assume no other contributions, rollovers, transfers, excess-contribution returns, or special funding distributions, and that applicable eligibility and limits are satisfied.
Under these assumptions, 2025 Box 2 is $2,500 and Box 3 is $400. The ordinary contributions attributable to 2025 are $2,500 − $300 + $400 = $2,600. Simply adding Boxes 2 and 3 would give $2,900 and incorrectly include the $300 for 2024.
This example is a record-matching calculation, not a general formula that resolves every HSA case. Contributions treated as employer contributions, special IRA-to-HSA funding, excess returns, eligibility changes, and multiple custodians require their own treatment. The $2,600 is not automatically deductible by the participant.
How does Form 5498-SA relate to payroll and W-2 Code W?
IRS Publication 969 explains that employer HSA contributions are not personally deductible and that employee salary reductions made through a cafeteria plan are treated as employer contributions. The same funding can appear in payroll, W-2 Code W, and the custodian's records without representing three separate contributions.
For example, if the fictional $2,200 consisted entirely of employer and cafeteria-plan payroll contributions for 2025, do not claim that amount again as your own separate HSA deduction. Review any personally made contribution, such as the assumed $400, under the applicable Form 8889 instructions, eligibility conditions, and contribution limit.
The HSA pay-stub guide explains payroll deductions, employer funding, and the W-2 link. Reconcile deposit dates as well as deductions: a deduction recorded on payroll and a later custodian posting may need a timing explanation rather than a duplicate entry.
Are rollovers and direct transfers the same for reporting?
No. The 2025 instructions report qualifying HSA or Archer MSA rollover contributions in Box 4, separately from ordinary contributions in Box 2. They also say not to report direct HSA-to-HSA trustee transfers as contributions or rollovers on these forms. Keep the transfer paperwork so moving an existing balance is not mistaken for new payroll funding.
Do not extend that rule to every transfer from every account type. A qualified IRA-to-HSA funding distribution has special rules and is included in Box 2 under the instructions. Ask the custodian to identify the transaction type before relabeling it.
Form 1099-SA concerns distributions rather than contributions. Our 1099-SA guide explains why a distribution statement, a medical receipt, and a contribution statement serve different purposes.
Why can Form 5498-SA arrive after filing season begins?
Prior-year contribution reporting can include deposits made in the following year. For the 2025 form specifically, the IRS instructions set June 1, 2026, for the required participant statement and IRS filing, subject to their stated exceptions. That is the 2025 form's deadline, not a date to copy automatically to another year.
The participant instructions say not to attach Form 5498-SA to the income-tax return; keep it for your records. Use reliable contribution records and the applicable return instructions rather than assuming that a later statement excuses a filing deadline. HSA reporting commonly involves Form 8889; the IRS Form 8889 page links to the applicable form and instructions.
What should you check if the form looks wrong?
- Correct account owner, account type, account identifier, and form year.
- Deposit dates and the year assigned to each contribution.
- Employer funding, cafeteria-plan reductions, and personal deposits counted once.
- Rollovers, direct transfers, excess returns, and corrected statements distinguished.
- The December 31 value compared with the corresponding account statement.
Ask the issuing custodian about an incorrect form and payroll about an incorrect wage statement. Keep the original, correction, and explanation. If you already filed using different information, check whether your return needs amendment; a changed account value alone does not automatically mean every tax figure was wrong.
Common Form 5498-SA questions
Is Box 5 extra taxable income?
It reports the account's year-end fair market value. It is not, by itself, an additional wage payment, contribution, or taxable distribution.
Can I deduct every amount on the form?
No. Account type, contribution source, year, eligibility, limits, and special transaction rules matter. Employer and cafeteria-plan contributions cannot simply be deducted again as personal contributions.
Should I create this form from my pay stubs?
The trustee or custodian issues the form from its account records. A payroll statement alone does not establish all deposits, transfers, year designations, or the year-end value.
