What is Form 8889 for?
Form 8889 is the IRS form used to report contributions, distributions, and activity related to Health Savings Accounts. Most taxpayers file it with their tax return to show deductible contributions, qualified medical expenses, and any excess contributions that require additional tax. The form also confirms whether an eligible individual had self-only coverage or family coverage under a High Deductible Health Plan for the tax year.
When You’d Use Form 8889
You file Form 8889 whenever you or your employer contributes to your HSA during the year. Taxpayers also use it when reporting HSA distributions or correcting excess contributions that increase taxable income. Late or amended filing is allowed, and most taxpayers can correct amounts after receiving updated tax forms or trustee statements without losing tax benefits.
Key Rules or Details for 2025
- Eligibility requirements: An eligible individual must have a qualifying High Deductible Health Plan and no disqualifying medical coverage. This rule helps ensure HSA funds remain tax-free dollars and receive full tax advantages.
- Contribution limits: Total contributions include both deductible contributions you make and employer contributions made on your behalf by your employer. This matters because excess contributions can trigger additional tax and must be removed or appropriately reported.
- Last month rule: The previous month rule allows full-year contributions if eligible in December, but it requires maintaining coverage for the entire year. This prevents taxpayers from triggering additional income or penalties when filing the IRS form.
- Qualified medical expenses: HSA distributions remain tax-free only when used for qualified medical expenses incurred after the savings account is opened. This distinction prevents taxpayers from misusing their funds and owing additional tax.
- Rollovers and transfers: A rollover contribution or a qualified HSA funding distribution from a Traditional IRA must follow specific form instructions. These rules help taxpayers avoid situations where they lose money or create unnecessary taxable income.

Step-by-Step (High Level)
Step 1: Gather contribution information
Collect tax forms from your HSA trustee that show the total contributions and distributions for the tax year. This ensures your HSA reporting matches IRS records and avoids unnecessary delays on the taxpayer’s return.
Step 2: Confirm your annual contribution limit
Review whether you had self-only or family coverage under a High Deductible Health Plan. This helps calculate allowable HSA contributions and prevents excess contributions that can create additional tax.
Step 3: Enter your distributions accurately
Use trustee statements to report distributions and indicate whether they were used for qualified medical expenses. This protects the tax-free treatment of HSA funds and avoids unnecessary adjustments.
Step 4: Complete tax and penalty calculations
If you used HSA money for nonmedical expenses, you must calculate additional income and penalties. This step ensures that your tax return accurately reflects your income and that the IRS receives clear and accurate figures.
Step 5: Attach Form 8889 to your return
Attach the completed form to your main tax return and confirm the totals flow correctly to all required schedules. This keeps your HSA deduction accurate while preventing reporting issues.

Common Mistakes and How to Avoid Them
- Overcontributing to the HSA: Taxpayers sometimes overlook employer contributions when calculating total contributions. You can avoid excess contributions by reviewing your W-2 and trustee statements and comparing them to annual IRS limits.
- Incorrectly reporting employer contributions: Employer contributions should not be listed as personal HSA contributions. You can prevent this mistake by entering employer deposits only where the IRS form instructions specifically require it.
- Using HSA funds for non-qualified expenses: Spending HSA money on non-medical purchases adds additional tax and penalties. You can avoid this by keeping receipts and confirming that each expense is a qualified medical expense under IRS rules.
- Failing the last month rule: Taxpayers sometimes contribute for the entire year without maintaining the required coverage for the entire year. You can prevent additional tax by ensuring you stay eligible through the entire testing period.
- Not tracking rollovers correctly: Misreporting a rollover contribution can create incorrect taxable income. You can avoid this by verifying transfers and following the instructions for IRA rollovers or HSA-to-HSA transfers.

What Happens After You File
After filing Form 8889, the IRS reviews your HSA reporting alongside information received from your HSA trustee. Your HSA deduction flows to your main tax return, while non-qualified distributions increase taxable income. If discrepancies appear, the IRS contacts you for clarification. The HSA continues to earn interest and accumulate savings, allowing most taxpayers to save money over time while maintaining tax-free access to qualified medical expenses.
