Health Savings Account information appears on Form 1040 and Schedule 1

Your Health Savings Account (HSA) contributions and distributions show up in two places on your federal tax return. If you contributed to an HSA during the year, those contributions appear on Form 1040 (the main tax form) on line 12, labeled "HSA deduction." If you received distributions from your HSA, that information goes on Schedule 1 (Additional Income and Adjustments), line 21, labeled "Distributions from HSAs."

The exact line numbers can shift slightly from year to year as the IRS updates forms, but the labels stay consistent. Your tax software will place HSA information in these sections automatically if you enter the data correctly during setup. If you are filing by hand, the instructions that come with Form 1040 will tell you which lines to use for the current tax year.

Your HSA custodian — the bank or financial institution that holds your account — sends you a Form 5498-SA by May 31 each year. This form shows how much you (or your employer) put into the account during the prior year. You will also receive a Form 1099-SA if you took any money out. Both forms are information returns; you do not file them with the IRS, but you use the numbers from them to fill in your tax return.

Key Takeaways

  • HSA contributions you made yourself appear on Form 1040, line 12, as a deduction that lowers your taxable income.
  • Money you withdrew from your HSA shows on Schedule 1, line 21, and may be taxable if you did not use it for medical expenses.
  • Your HSA custodian sends Form 5498-SA (contributions) and Form 1099-SA (distributions) by May 31, and you use those numbers on your return.
  • Employer contributions to your HSA do not appear on your tax return because they are already excluded from your wages on your W-2.

Understanding Form 5498-SA and what it tells you

Form 5498-SA reports all money that went into your HSA during the tax year. Box 1 shows contributions you made yourself. Box 2 shows contributions your employer made on your behalf. Box 3 shows any rollover deposits from another HSA. The form also includes a box for the fair market value of your account as of December 31.

You need the number from Box 1 (your own contributions) to fill in line 12 of Form 1040. If your employer made contributions, those do not go on your tax return because they were already left out of your W-2 wages. The form is sent to you and to the IRS, so the IRS already knows what you contributed. If the number on Form 5498-SA does not match what you actually put in, contact your HSA custodian to request a corrected form.

Understanding Form 1099-SA and taxable withdrawals

Form 1099-SA reports money you took out of your HSA. Box 1a shows the total amount distributed. Box 1b shows how much of that was for medical expenses. The difference between those two numbers is the amount that may be taxable to you.

If you withdrew money only for may have access to medical expenses — doctor visits, prescriptions, dental work, vision care, and similar costs — that withdrawal is not taxable and does not go on your return. If you withdrew money for any other reason, that amount is taxable income and goes on Schedule 1, line 21. You may also owe a 20 percent penalty tax on non-medical withdrawals if you are under age 65, though there are narrow exceptions (such as disability or Medicare enrollment).

The IRS does not require you to prove medical expenses when you file your return, but you should keep receipts and records in case of an audit. If you believe the amount in Box 1b on your Form 1099-SA is wrong — for example, because you used money for medical expenses but the custodian did not code it that way — you can still deduct the medical expenses on Schedule A (itemized deductions) if you itemize, though this is rarely the best approach.

How employer contributions show up differently

When your employer puts money into your HSA, that amount is deducted from your paycheck before taxes are calculated. It shows up on your W-2 in Box 12 with code "W," which means it is a pre-tax contribution. Because it was already excluded from your wages, you do not claim it again as a deduction on Form 1040.

Your HSA custodian will still report the employer contribution on Form 5498-SA (in Box 2), and the IRS will see it there. But you do not enter it on your tax return. The only HSA contributions that go on your return are the ones you made with after-tax money — money that came out of your paycheck after taxes were taken out, or money you contributed outside of payroll.

What to do if your HSA information is missing from your return

If you made HSA contributions but did not report them on your tax return, you can still claim the deduction by filing an amended return using Form 1040-X. You have three years from the original due date of the return to amend it and claim the deduction. This matters because HSA contributions reduce your taxable income, which can lower your tax bill or increase your refund.

If you received a Form 1099-SA showing a distribution but did not report it on your return, and the money was not used for medical expenses, the IRS may assess tax and penalties based on the form they received. It is better to report the distribution yourself and explain any non-medical use than to wait for the IRS to contact you.

If you lost your Form 5498-SA or Form 1099-SA, contact your HSA custodian and ask for a duplicate. You can also call the IRS at 800-829-1040 and ask them to mail you a copy of the forms they received on file for you, though this takes several weeks.

HSA deductions on Schedule 1 versus Form 1040

For tax years 2020 and later, HSA contributions you made yourself go on Form 1040, line 12, not on Schedule 1. This is an "above-the-line" deduction, which means it reduces your adjusted gross income (AGI) whether you itemize deductions or take the standard deduction. That makes it more valuable than a deduction that only helps if you itemize.

Schedule 1 is used for HSA distributions (withdrawals), not contributions. If you took money out of your HSA and some or all of it was not for medical expenses, that taxable portion goes on Schedule 1, line 21. The two forms work together: contributions lower your income on Form 1040, and distributions (if taxable) raise your income on Schedule 1.

Frequently Asked Questions

Do I have to report HSA contributions if my employer made them all?

No. Employer contributions are already excluded from your W-2 wages, so they do not go on your tax return. You only report contributions that you made yourself with after-tax money. If you are unsure whether a contribution was from your employer or from you, check your pay stubs or ask your employer's benefits department.

What counts as a may have access to medical expense for HSA withdrawals?

may have access to expenses include doctor and dentist visits, prescriptions, glasses and contacts, hearing aids, mental health treatment, and most other costs related to diagnosis, cure, mitigation, treatment, or prevention of disease. Over-the-counter medicines (except insulin) do not count unless you have a prescription. Cosmetic procedures, gym memberships, and vitamins do not count. The IRS publishes a full list in Publication 502.

Can I claim HSA contributions on my return if I did not receive a Form 5498-SA?

Yes. You can report contributions based on your own records — bank statements, cancelled checks, or receipts from your HSA custodian. However, the IRS will also have received Form 5498-SA from your custodian, so make sure your numbers match. If they do not, contact your custodian first to see if a corrected form is needed.

What happens if I withdraw HSA money for non-medical reasons before age 65?

The withdrawal amount is taxable as income, and you owe a 20 percent penalty tax on top of regular income tax. After age 65, you can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals. The exception is if you become disabled or enroll in Medicare before 65 — in those cases, the penalty does not explore.

Where do I find my HSA information if I changed custodians during the year?

You will receive separate Form 5498-SA and Form 1099-SA from each custodian. Add up all contributions from all Form 5498-SA forms and report the total on line 12 of Form 1040. Add up all distributions from all Form 1099-SA forms and report the total on Schedule 1, line 21. Keep all forms with your tax records.
