Form 8889 Instructions: HSA Contributions, Deductions, and Distributions
Form 8889, Health Savings Accounts, reports HSA contributions and distributions, calculates the taxpayer's HSA deduction, and reports income and additional tax after certain testing-period failures. A taxpayer may need it even when every HSA withdrawal paid qualified medical expenses. This guide covers the 2025 form filed during the 2026 filing season.

Quick reference
Form 8889 at a Glance
Question; Quick answer
- What is Form 8889?
- The federal HSA tax form for contributions, deductions, distributions, and certain testing-period consequences.
- Who generally files it?
- An HSA owner with contributions, distributions, a testing-period failure, or specified beneficiary reporting after death.

- $4,300 for self-only coverage and $8,550 for family coverage, plus a possible $1,000 age-55 catch-up.
- Is every contribution deductible?
- No. Employer and cafeteria-plan contributions are not deducted again, and eligibility and limits apply.

Key points
Key Takeaways
- File Form 8889 for an HSA distribution even when the full amount paid qualified medical expenses.
- Contribution eligibility is generally tested on the first day of each month unless the last-month rule applies.
- Cafeteria-plan payroll contributions belong on line 9 as employer contributions, not line 2.
- Form 1099-SA code 1 means a normal distribution, not automatically taxable or tax free.
- Qualified expenses must be incurred after the HSA was established and cannot be reimbursed or deducted twice.
- The 6%, 10%, and 20% additional taxes apply to different problems.
Form purpose
What Is Form 8889?
Form 8889 coordinates the HSA contribution limit, above-the-line deduction, employer funding, IRA-to-HSA funding distributions, HSA withdrawals, qualified medical expenses, and additional taxes.
The HSA tax deduction calculated on line 13 generally flows to Schedule 1, while employer and cafeteria-plan contributions are not deducted again.
| Part | Main purpose | General return destination |
|---|---|---|
| Part I | Calculates contribution capacity and the deductible contribution | Line 13 to Schedule 1, line 13 |
| Part II | Reports distributions and taxable nonmedical amounts | Line 16 to Schedule 1, line 8f; line 17b to Schedule 2, line 17c |
| Part III | Reports testing-period income and 10% additional tax | Line 20 to Schedule 1, line 8f; line 21 to Schedule 2, line 17d |
An HSA can reimburse qualified expenses for the account beneficiary, spouse, dependents, and certain people treated as dependents for HSA purposes. Contribution eligibility and withdrawal treatment are separate. A person may take distributions after losing contribution eligibility, including after Medicare enrollment.
Filing requirements
Who Must File Form 8889?
| 2025 event | Form generally required? |
|---|---|
| You, an employer, or another person contributed to your HSA for 2025 | Yes |
| Your HSA made a distribution | Yes, even if fully used for qualified expenses |
| You failed a last-month-rule or qualified-funding-distribution testing period | Yes |
| You acquired an HSA interest after the account beneficiary's death | Yes, with special rules |
| You only maintained an HSA without one of these events | Generally no for that reason alone |
| You had only an Archer MSA or Medicare Advantage MSA transaction | Generally use Form 8853 |
If you received an HSA distribution, or your spouse received one and you file jointly, attach Form 8889 to Form 1040, 1040-SR, or 1040-NR even if there is no other filing requirement. Form 8889 is not filed alone in that situation.
Prepare a separate form for each spouse who owns an HSA. Spouses may need to allocate a shared family limit, but one spouse's catch-up contribution cannot be placed in the other's HSA.

Form 8889 vs Forms 1099-SA, 5498-SA, and 8853
| Document | Main purpose |
|---|---|
| Form 8889 | Taxpayer calculation of deduction, distribution treatment, and testing-period consequences |
| Form 1099-SA | Custodian report of gross distributions, earnings on returned excess amounts, code, and account type |
| Form 5498-SA | Custodian report of contributions, rollovers, and year-end account value |
| Form W-2, code W | Employer and cafeteria-plan HSA contributions |

What Does 1099-SA Distribution Code 1 Mean?
Code 1 means a normal distribution to the account holder or a direct provider payment. It does not determine taxability. Other codes identify an excess distribution, disability, death, prohibited transaction, or specified post-death distribution. Report the gross amount and substantiate the qualified-expense portion. Ask the custodian about a corrected form when the code does not match the event.
Eligibility
Who Is Eligible to Contribute to an HSA?
For a month to count, an individual generally must be covered by a qualifying high deductible health plan on the first day, have no disqualifying additional coverage, not be enrolled in Medicare, and not be eligible to be claimed as another person's dependent.
An insurance plan described as “high deductible” is not automatically HSA-qualified. Confirm its section 223 status.
FSA, HRA, Medicare, VA, and Telehealth Rules
- HSA and FSA or HRA coverage: A general-purpose arrangement that pays expenses before the HDHP deductible can disqualify contributions. A spouse's FSA can also matter if it reimburses the taxpayer.
- HSA and Medicare: Enrollment ends contribution eligibility for enrolled months. Retroactive Part A coverage can create an excess, but Medicare does not prevent HSA withdrawals.
- HSA and VA care: Service-connected disability care does not by itself end eligibility. Other VA care can require further review.
- HSA and telehealth: For plan years beginning after 2024, qualifying remote-care coverage can be disregarded coverage and does not by itself prevent HDHP status.
Review actual plan terms, effective dates, grace periods, and carryovers rather than relying on labels.
Contribution limits
2025 HSA Contribution Limits
| Amount | 2025 | 2026 planning amount |
|---|---|---|
| Self-only HSA contribution limit | $4,300 | $4,400 |
| Family HSA contribution limit | $8,550 | $8,750 |
| Age-55 catch-up | $1,000 | $1,000 |
| Self-only HDHP minimum deductible | $1,650 | $1,700 |
| Family HDHP minimum deductible | $3,300 | $3,400 |
| Self-only maximum in-network out-of-pocket amount | $8,300 | $8,500 |
| Family maximum in-network out-of-pocket amount | $16,600 | $17,000 |
Use 2025 amounts on the 2025 form. The annual limit includes taxpayer, employer, family, and other regular contributions. Employer funding is not additional capacity. Rollovers generally do not consume the limit, but a qualified IRA-to-HSA funding distribution does.
The catch-up belongs to each eligible HSA owner age 55 or older at year end. Each spouse needs an HSA in that spouse's name for a separate catch-up.
Monthly Eligibility and the Last-Month Rule
Without a special rule, line 3 generally reflects eligible months and coverage type on the first day of each month. Under the last-month rule, someone eligible on December 1 may use the December coverage type for the full year but must remain eligible through December 31 of the next year.
For a contribution relying on the 2025 HSA last-month rule, the testing period runs from December 1, 2025, through December 31, 2026. Losing eligibility during it for a reason other than death or disability can make the extra contribution taxable in the failure year and subject to a 10% additional tax.
Before you start
What Records Do You Need?
Gather:
- Forms W-2, 1099-SA, and 5498-SA
- Payroll and direct-contribution records
- Monthly HDHP, Medicare, FSA, HRA, VA, and other coverage dates
- The HSA establishment date
- Medical receipts and reimbursement records
- Rollover, transfer, and IRA funding documents
- Prior Forms 8889 and 5329
- Death and beneficiary records when applicable
Reconcile the contribution year. An early-2026 contribution may be designated for 2025, while payroll records may require timing adjustments under the employer contribution worksheet.
Form walkthrough
How to Fill Out Form 8889
Part I: Contributions and Deduction
| Line or group | Purpose |
|---|---|
| Lines 1 through 3 | Identify coverage and calculate the annual or monthly limit |
| Lines 4 through 8 | Account for Archer MSA amounts, spouse allocation, and catch-up contributions |
| Line 9 | Report employer contributions, including cafeteria-plan payroll contributions |
| Line 10 | Report a qualified IRA-to-HSA funding distribution |
| Lines 11 through 13 | Calculate remaining capacity and the HSA deduction |
Do not enter cafeteria-plan payroll contributions again on line 2. For a 2025 direct contribution made in 2026, include it only if timely and designated for 2025. When spouses share a family limit, they generally divide the basic limit equally unless they agree otherwise; catch-ups remain individual.
Part II: HSA Distributions
| Line | Purpose |
|---|---|
| 14a | Gross HSA distributions, generally from Form 1099-SA box 1 |
| 14b | Qualifying rollovers and timely returned excess contributions, including related earnings, when included in 14a |
| 14c | Net distributions |
| 15 | Amount used for qualified medical expenses |
| 16 | Taxable nonqualified amount |
| 17a and 17b | Death, disability, or age-65 exception and any 20% additional tax |
The taxpayer, not the custodian, substantiates qualified expenses. A direct provider payment and a later reimbursement can both qualify when the underlying requirements are met.
Part III: Testing-Period Failures
Line 18 addresses a failed last-month-rule testing period. Line 19 addresses a failed qualified HSA funding distribution testing period. Line 20 reports resulting income, and line 21 calculates the 10% additional tax.
Do not confuse this 10% tax with the Part II 20% tax on nonqualified distributions or the Form 5329 6% excise tax on uncorrected excess contributions.
Worked examples
Form 8889 Examples
Example 1: Contribution and Deduction
An eligible taxpayer under 55 had self-only coverage all year, contributed $3,000 directly, and received $1,300 from the employer:
2025 limit: $4,300
Taxpayer contribution, line 2: $3,000
Employer contribution, line 9: $1,300
Deduction, line 13: $3,000Total funding equals the limit. Only the taxpayer's direct contribution is deducted.
Example 2: Partly Nonqualified Distribution
The taxpayer receives $2,000 and substantiates $1,800 of qualified expenses. No exception applies:
Gross distribution, line 14a: $2,000
Qualified expenses, line 15: $1,800
Taxable amount, line 16: $200
Additional tax at 20%, line 17b: $40The $200 is generally income and the $40 generally reaches Schedule 2. An exception can remove the additional tax without removing the taxable income.
Tax guidance
HSA Distributions and Qualified Medical Expenses
An HSA distribution is federally tax free to the extent it pays or reimburses qualified expenses for eligible people. The expense must arise after the HSA was established and cannot be reimbursed elsewhere or also deducted on Schedule A.
Qualified expenses generally follow section 213 and include specified medicines and menstrual-care products. Most insurance premiums do not qualify. Main exceptions include qualified long-term-care premiums within limits, COBRA or continuation coverage, coverage while receiving unemployment compensation, and Medicare or other coverage after age 65, excluding Medigap.
HSA Reimbursement Timing
Federal rules generally impose no fixed deadline for reimbursing a qualified expense incurred after HSA establishment. The taxpayer must prove the expense, show it was not previously reimbursed or deducted, and connect it to the distribution. See IRS Notice 2004-50, Q&A 39. Keep receipts and a reimbursement ledger.
Tax guidance
HSA Rollovers, Transfers, and IRA-to-HSA Funding
| Transaction | Basic treatment |
|---|---|
| 60-day HSA rollover | Redeploy a distribution into an HSA of the same beneficiary, generally within 60 days; normally one during a one-year period. Report gross and rollover amounts in Part II. |
| Direct trustee transfer | Not treated as a contribution or distribution and not numerically limited. Omit from lines 2 and 14a. |
| Qualified HSA funding distribution | Direct IRA-to-HSA transfer reported on line 10; generally once per lifetime, not income or deductible, and uses contribution capacity. |
An IRA-to-HSA funding distribution cannot come from an ongoing SEP or SIMPLE IRA. Its testing period begins with the contribution month and ends on the last day of the twelfth following month. A failure generally creates income and a 10% additional tax.
Tax guidance
Excess HSA Contributions and Testing-Period Failures
An excess can result from exceeding the limit, losing eligibility, Medicare enrollment, overlapping coverage, or overlooking employer funding. To treat a 2025 excess as not contributed, the taxpayer generally must withdraw it and attributable earnings by the return due date, including extensions, avoid a deduction or exclusion for the excess, and report the earnings correctly. An amount left in the HSA can face a 6% Form 5329 excise tax for each year it remains, subject to the statutory calculation.
A testing-period failure is different. It can create income plus a 10% tax under Part III in the year eligibility is lost.
After an HSA owner's death, a surviving-spouse beneficiary generally treats the HSA as the spouse's own. For a nonspouse beneficiary other than the estate, the account ceases to be an HSA and its date-of-death value is generally taxable, reduced by eligible decedent medical expenses the beneficiary pays within one year. If the estate is beneficiary, the value is generally included on the decedent's final return, without that estate reduction.
Filing guidance
How and When to File Form 8889
Attach Form 8889 to Form 1040, 1040-SR, or 1040-NR. For most calendar-year taxpayers, the unextended 2025 return and HSA contribution deadline was April 15, 2026. A valid filing extension generally moved the return deadline to October 15, 2026, but did not extend the normal contribution deadline or time to pay.
If information is corrected after filing, determine whether Form 1040-X and a corrected Form 8889 are needed. Retain the explanation, corrected forms, and supporting records.

Filing questions
Form 8889 Frequently Asked Questions
Must I file if every withdrawal paid medical expenses?
Yes. Form 8889 reports the gross distribution and establishes the qualified-expense amount.
Is an HSA contribution tax deductible?
Eligible direct contributions can produce an above-the-line deduction. Employer and cafeteria-plan contributions are not deducted again.
What was the 2025 HSA contribution deadline?
For most taxpayers, it was April 15, 2026. A filing extension generally did not extend it.
Can I contribute after age 65?
Age alone does not end eligibility, but Medicare enrollment does. Check for retroactive Part A coverage.
Can I use HSA money after enrolling in Medicare?
Yes. Qualified withdrawals can remain tax free. The 20% additional tax no longer applies after age 65, although a nonqualified amount remains taxable.
What is the HSA withdrawal penalty?
A nonqualified distribution is generally included in income and faces a 20% additional tax. The additional tax does not apply after the account beneficiary dies, becomes disabled, or turns 65, although the taxable-income rule can still apply.
Does unused HSA money roll over each year?
Yes. The balance is not forfeited. This annual carryforward differs from moving money between HSAs.
Can I reimburse myself years later?
Generally yes, when the post-establishment expense remains qualified, unreimbursed, undeducted, and fully documented.
