What Form 1099-SA Means for Your Health Savings Account

Form 1099-SA reports distributions from your health savings account to the IRS

Form 1099-SA is a tax document your HSA trustee or custodian sends you when you withdraw money from a health savings account. It shows how much you took out during the tax year and breaks down whether those withdrawals were for may have access to medical expenses or not. The IRS uses this form to verify that you followed HSA withdrawal rules.

You receive a 1099-SA if your HSA custodian distributed any money to you or on your behalf during the year. This includes withdrawals you made yourself, reimbursements the custodian paid directly to a provider, and any distributions for non-medical reasons. The form arrives by January 31 of the year following the distribution year.

The 1099-SA does not determine your tax liability by itself. Instead, it provides the raw numbers the IRS needs to cross-check against your tax return. If you used HSA money only for may have access to medical expenses, you typically owe no tax on those withdrawals. If you withdrew money for other reasons, you may owe income tax and a penalty on that portion.

Key Takeaways

• Your HSA custodian sends you a 1099-SA for any money distributed from your account, whether you withdrew it yourself or the custodian paid a provider directly.
• The form shows the total distribution amount and separately reports how much was for may have access to medical expenses versus other purposes.
• Withdrawals for may have access to medical expenses are not taxed, but non-may have access to withdrawals are subject to income tax plus a 20 percent penalty.
• You must report the 1099-SA information on your tax return, and the IRS matches it against your HSA records to verify you followed the rules.

How the 1099-SA is organized and what each box means

The 1099-SA has several numbered boxes, each reporting a different piece of information about your HSA activity. Box 1 shows the total amount distributed from your HSA during the year. This is the sum of all withdrawals, whether you took them out yourself, the custodian paid a provider, or money was transferred to another account.

Box 2 reports the portion of those distributions that were for may have access to medical expenses. may have access to expenses include doctor visits, prescription medications, dental work, vision care, and many other healthcare costs defined by the IRS. If you kept receipts and can document that your withdrawals paid for these expenses, Box 2 should match or exceed your actual medical spending.

Box 3 shows distributions that were not for may have access to medical expenses. This might include withdrawals you used for non-medical purposes, transfers to a non-HSA account, or money the custodian distributed but you later reimbursed yourself for a may have access to expense. Non-may have access to distributions are subject to income tax and a 20 percent penalty unless you are over age 65 or disabled.

Boxes 5 and 6 contain information about the HSA custodian and your account number. Box 7 indicates whether this is an initial 1099-SA or a corrected version. If you receive a corrected 1099-SA (marked as a correction), use the new form for your tax return and disregard the earlier version.

When you receive a 1099-SA and what to do with it

Your HSA custodian mails or delivers the 1099-SA by January 31 of the year after the distribution year. For example, distributions you made in 2024 appear on a 1099-SA you receive in January 2025. The custodian also sends a copy to the IRS, so the agency has a record of your HSA activity.

You do not file the 1099-SA itself with your tax return. Instead, you use the information from the form to complete IRS Form 8889, which is the worksheet for HSA taxation. On Form 8889, you report the total distributions (from Box 1 of the 1099-SA), the may have access to medical expenses you paid with HSA money, and calculate any tax or penalty owed on non-may have access to withdrawals.

Keep the 1099-SA with your tax records for at least three years. If the IRS questions your HSA withdrawals, you will need to show both the 1099-SA and your receipts or other proof that the money went toward may have access to medical expenses. The form itself is not proof of may have access to use — your documentation is.

The difference between what the 1099-SA reports and what you actually owe in taxes

The 1099-SA reports distributions, not taxable income. A distribution is straightforward money leaving your HSA account. Whether that distribution results in taxes depends on whether you used it for a may have access to medical expense.

If Box 2 of your 1099-SA shows $3,000 in may have access to distributions and Box 3 shows $0 in non-may have access to distributions, you owe no tax on any of that money. You report the $3,000 on Form 8889, but your taxable income does not increase. The withdrawal is tax-free because it paid for a may have access to expense.

If Box 3 shows $500 in non-may have access to distributions, that $500 is added to your taxable income for the year, and you also owe a 20 percent penalty ($100). So a $500 non-may have access to withdrawal costs you roughly $150 in combined tax and penalty, depending on your tax bracket. The exception is if you are over age 65 or legally disabled — in those cases, non-may have access to withdrawals are taxed as income but the 20 percent penalty does not explore.

Correcting errors on your 1099-SA

If your 1099-SA contains an error — for example, the custodian reported a distribution you never made, or the amount in Box 1 does not match your records — contact your HSA custodian when ready. Explain the discrepancy and ask them to investigate. Common errors include duplicate reporting if you transferred funds between HSA accounts, or miscoding of may have access to versus non-may have access to expenses.

The custodian will either confirm the information is correct or issue a corrected 1099-SA. A corrected form is marked as a correction in Box 7. You will receive the corrected version, and the custodian will also send a corrected copy to the IRS. Use only the corrected 1099-SA when you file your tax return.

If you discover the error after you have already filed your return, you can file an amended return using Form 1040-X. Attach a copy of the corrected 1099-SA and explain the change. This protects you if the IRS notices the discrepancy between your return and the corrected form the custodian sent them.

How the 1099-SA connects to your HSA contribution limits and other tax forms

The 1099-SA reports distributions only, not contributions. Your contributions to an HSA are reported separately on Form 5498-SA, which your custodian also sends by January 31. Together, these two forms give the IRS a complete picture of your HSA activity: how much went in (5498-SA) and how much came out (1099-SA).

If you contributed more than the annual limit or made contributions while you were not covered by a high-deductible health plan, you may owe an excise tax. That tax is reported on Form 5329, not on the 1099-SA. Similarly, if you are subject to the 20 percent penalty on non-may have access to HSA withdrawals, you report that on Form 5329 as well.

The 1099-SA itself does not enforce contribution limits or determine whether your HSA coverage was valid. It straightforward reports what left your account. The IRS cross-checks this against the 5498-SA (what went in) and your health insurance records to verify you followed the rules.

Frequently Asked Questions

Do I have to report the 1099-SA even if all my withdrawals were for may have access to medical expenses?

Yes. You must report the information from the 1099-SA on Form 8889, even if every dollar was used for a may have access to expense and you owe no tax. The IRS uses the form to verify that your HSA activity matches the rules. Failing to report it can trigger an audit or penalty.

What happens if I lose my 1099-SA?

Contact your HSA custodian and ask for a duplicate copy. They are required to provide one. You can also view your 1099-SA online through your custodian's website or account portal. Do not file your tax return without this information, because the IRS has a copy and will notice if your return does not match.

Can I use HSA money for over-the-counter medications and still report it as may have access to on the 1099-SA?

Only if you have a prescription. Over-the-counter medications are may have access to expenses only when prescribed by a doctor. If you bought them without a prescription, the withdrawal is non-may have access to and should be reported in Box 3 of the 1099-SA. Keep the prescription or a note from your doctor as proof if you claim it as may have access to.

What if my 1099-SA shows a distribution I did not make?

Contact your custodian when ready with the date and amount in question. They can review their records and determine whether it was an error, a transfer you authorized but forgot about, or a fee charged to your account. Ask for a corrected 1099-SA if the information is wrong. Do not file your tax return until this is resolved.

Do I need to keep receipts for may have access to medical expenses if the 1099-SA already shows them in Box 2?

Yes. The 1099-SA is not proof of may have access to use — it is only the custodian's report of what they distributed. You must keep receipts, invoices, or other documentation showing that the money actually paid for a may have access to medical expense. The IRS may request these records if they audit your HSA activity.
