Health Savings Accounts (HSAs) offer one of the most powerful tax advantages available to American taxpayers: triple tax savings. You get a tax deduction when you contribute, your money grows tax-free, and withdrawals for qualified medical expenses are tax-free. However, with these substantial benefits comes the responsibility of proper tax reporting. If you have an HSA, you'll encounter several tax forms that document your contributions, distributions, and account activity and understanding these forms is essential for maintaining your HSA's tax-advantaged status.
Navigating HSA tax forms can feel overwhelming, especially if you're new to these accounts or unfamiliar with tax reporting requirements. Between Form 5498-SA, Form 1099-SA, and Form 8889, each document serves a specific purpose in reporting your HSA activity to the IRS. Missing or misreporting information from these forms can result in penalties, lost tax benefits, or unwanted scrutiny from the IRS. This comprehensive guide will walk you through each HSA tax form, explain what information they contain, and show you how to properly report your HSA activity on your tax return.
Three primary tax forms are associated with Health Savings Accounts, and each serves a distinct purpose in documenting your HSA activity. Form 5498-SA reports contributions made to your HSA during the tax year and arrives from your HSA custodian or trustee. Form 1099-SA documents any distributions or withdrawals you took from your HSA throughout the year. Form 8889 is the form you complete and file with your tax return to report all HSA contributions, distributions, and calculate any applicable taxes or penalties.
These forms work together to create a complete picture of your HSA activity for the IRS. Your HSA administrator sends Forms 5498-SA and 1099-SA to both you and the IRS, providing the government with independent verification of your account activity. You then use the information from these forms to complete Form 8889, which you attach to your Form 1040 when filing your tax return. Understanding how these forms interconnect is crucial because the IRS cross-checks the information you report against what your HSA custodian reports. Discrepancies can trigger inquiries, audits, or adjustments to your tax return.
Form 5498-SA reports all contributions made to your HSA during the tax year, including contributions you made yourself, contributions your employer made on your behalf, and any rollovers from other HSAs or Archer MSAs. Box 2 shows your total HSA contributions, Box 3 indicates the total value of your account as of December 31st, and Box 4 reports any HSA contributions made between January 1st and the tax filing deadline (typically April 15th) that were designated for the previous tax year.
You'll receive Form 5498-SA from your HSA custodian by May 31st, which is later than most tax forms because HSA contributions can be made up until the tax filing deadline for the previous tax year. This timing is similar to IRA reporting and often confuses account holders who wonder why they're receiving forms after tax season. The good news is that you don't need to wait for Form 5498-SA to file your tax return, since you should already know how much you contributed based on your own records. However, when you receive the form, verify that the contribution amounts match what you reported on your tax return. Any discrepancies should be addressed immediately by contacting your HSA administrator or filing an amended return if necessary.
Form 1099-SA reports all distributions or withdrawals you made from your HSA during the tax year. Box 1 shows the gross distribution amount the total money you withdrew from your account. Box 3 includes a distribution code that indicates the type of distribution, with code "1" being the most common, signifying a normal distribution. Box 4 shows the fair market value of the account, though this box is rarely used for HSAs.
Unlike Form 5498-SA, Form 1099-SA typically arrives by January 31st, along with other common tax forms like W-2s and 1099s. This earlier timeline makes sense because it reports activity that occurred during the previous calendar year with no provisions for contributions after year-end. You should receive Form 1099-SA any year you took money out of your HSA, regardless of whether you used the funds for qualified medical expenses. This is a critical point many HSA holders misunderstand: receiving Form 1099-SA doesn't mean you owe taxes on the distribution. Whether the distribution is taxable depends entirely on whether you used the money for qualified medical expenses, which you'll report on Form 8889.
Form 8889 is the form you complete and attach to your Form 1040 when filing your tax return. This is where all your HSA activity comes together, and it's the most important HSA tax form because it determines your actual tax liability or deduction. Part I of Form 8889 addresses contributions, allowing you to claim a deduction for eligible contributions you made to your HSA. Part II deals with distributions, where you report withdrawals and indicate whether they were used for qualified medical expenses.
Completing Form 8889 requires careful attention to detail. You'll need information from both Form 5498-SA and Form 1099-SA, along with your own records of qualified medical expenses. The form calculates your allowable HSA contribution limit based on your coverage type (self-only or family), the months you were HSA-eligible during the year, and whether you're 55 or older (which allows catch-up contributions). If you took distributions for non-qualified expenses, Form 8889 calculates the income tax and 20% penalty tax you owe. Everyone who contributes to or takes distributions from an HSA during the tax year must file Form 8889 with their tax return, even if all distributions were for qualified medical expenses.
Reporting HSA contributions properly ensures you receive the full tax deduction you're entitled to while avoiding contribution limit penalties. When you complete Form 8889, you'll first determine your contribution limit based on your coverage type and eligibility period. For 2025, the contribution limit is $4,300 for self-only coverage and $8,550 for family coverage, with an additional $1,000 catch-up contribution allowed for those 55 and older.
You'll report three types of contributions separately on Form 8889: your personal contributions, employer contributions, and any rollovers. Personal contributions you made yourself are deductible and reduce your taxable income. Employer contributions, including those made through cafeteria plans via payroll deduction, are already excluded from your W-2 income and aren't deducted again on your tax return. If you contributed more than the allowed limit, you'll need to calculate the excess contribution penalty of 6% per year until the excess is removed. The key to accurate reporting is maintaining detailed records throughout the year, including contribution receipts, HSA statements, and documentation showing which months you had HSA-eligible health coverage.
Reporting distributions correctly on Form 8889 is crucial because this determines whether your withdrawals remain tax-free or become taxable income with penalties. In Part II of Form 8889, you'll report the total distributions from Box 1 of your Form 1099-SA. Then you'll indicate how much of those distributions were used for qualified medical expenses. If all your distributions paid for qualified expenses, they remain tax-free and penalty-free.
Qualified medical expenses include a wide range of healthcare costs not covered by insurance: deductibles, copayments, prescription medications, dental care, vision care, and many other IRS-approved medical expenses. However, you cannot use HSA funds tax-free for health insurance premiums (with limited exceptions like COBRA, Medicare, or premiums while receiving unemployment). If you used HSA distributions for non-qualified expenses, those amounts become taxable income and are subject to a 20% penalty tax unless you're over 65, disabled, or deceased. The burden of proof lies with you to demonstrate that distributions were used for qualified expenses, which is why maintaining receipts and documentation is essential. The IRS can audit HSA distributions for up to three years, and without proper documentation, all distributions could be treated as taxable income.
One of the most frequent errors HSA holders make is failing to file Form 8889 altogether. Some people mistakenly believe that if all their distributions were for qualified medical expenses, they don't need to file anything. This is incorrect if you had any HSA contributions or distributions during the year, you must file Form 8889 with your tax return. Failing to file this form can result in IRS inquiries and potential penalties.
Another common mistake involves mismatching information between the forms you receive and what you report on Form 8889. If the contribution amount on your Form 8889 doesn't match the amount your HSA custodian reported on Form 5498-SA, the IRS computers will flag the discrepancy. Similarly, distribution amounts must match between Form 1099-SA and Form 8889. Some taxpayers also forget to account for employer contributions, which shouldn't be claimed as deductions since they're already excluded from income on your W-2. Contributing to an HSA when you're not eligible such as being enrolled in Medicare, being claimed as a dependent, or having non-HDHP coverage is another serious error that can invalidate your HSA's tax benefits. Always verify your HSA eligibility before making contributions.
While many HSA holders can successfully navigate these forms on their own, certain situations warrant professional assistance. If you changed jobs mid-year, switched between self-only and family coverage, had gaps in HSA eligibility, or turned 65 and enrolled in Medicare, your Form 8889 becomes significantly more complex. Self-employed individuals claiming the self-employed health insurance deduction alongside HSA contributions need to coordinate these benefits carefully.

Do I need to attach receipts for qualified medical expenses to my tax return?
No, you do not attach receipts or documentation of qualified medical expenses to your tax return when filing. However, you must keep these records for at least three years in case of an IRS audit. The IRS may request proof that your HSA distributions were used for qualified medical expenses, so maintain detailed receipts, invoices, and explanations of benefits statements for all medical expenses you paid with HSA funds.
What happens if I used HSA money for non-medical expenses?
If you use HSA funds for non-qualified expenses, the distribution becomes taxable income that must be reported on Form 8889 and included on your Form 1040. Additionally, you'll pay a 20% penalty tax on the non-qualified distribution. However, the 20% penalty does not apply if you're 65 or older, disabled, or in the event of death. The income tax still applies regardless of age or circumstances.
Can I contribute to my HSA after December 31st for the previous tax year?
Yes, similar to IRAs, you can make HSA contributions up until the tax filing deadline (typically April 15th) and designate them for the previous tax year. When making the contribution, inform your HSA administrator which tax year it should be applied to. These contributions will be reported on the Form 5498-SA issued in May but can be claimed on the tax return filed in April.
Why didn't I receive Form 5498-SA or Form 1099-SA?
You'll only receive Form 1099-SA if you took distributions from your HSA during the year. If you only contributed but didn't withdraw any money, you won't receive this form. Form 5498-SA is issued when contributions were made to your account. If you only took distributions without making any contributions during the year, you might not receive Form 5498-SA. However, most HSA custodians send Form 5498-SA even without contributions to report year-end account values.
Do employer HSA contributions count toward my contribution limit?
Yes, employer contributions count toward your annual HSA contribution limit. The limit applies to the combined total of contributions from all sources your personal contributions, employer contributions, and any contributions from other family members. If your employer contributes $2,000 and your 2025 limit is $4,300 for self-only coverage, you can only contribute $2,300 yourself without exceeding the limit.
How do I fix an HSA over-contribution?
If you contributed more than the annual limit, you should withdraw the excess contribution plus any earnings on that excess before the tax filing deadline to avoid the 6% excise tax penalty. Contact your HSA administrator to request an excess contribution removal. If you don't remove the excess by the deadline, you'll pay a 6% penalty on the excess amount for each year it remains in the account, and you must file Form 5329 to report the penalty.
Do I need to file Form 8889 if I only made contributions but no withdrawals?
Yes, you must file Form 8889 if you made any contributions to your HSA during the tax year, even if you didn't take any distributions. The form is necessary to claim your contribution deduction and to report to the IRS that your contributions were within the allowed limits. Filing Form 8889 is required for anyone with HSA activity during the tax year.
Can I use HSA funds to pay for my spouse's medical expenses if we file separately?
If you have self-only HSA coverage and file taxes separately, you can still use your HSA to pay for your spouse's qualified medical expenses tax-free. The qualified medical expense rules apply to expenses for you, your spouse, and your dependents, regardless of your tax filing status. However, if you file separately, only the person who owns the HSA can claim the deduction for contributions made to that specific account.
