1099 SA Form: What It Is and How to Report It (2026)

If you offer an HSA plan, your team gets HSA tax documents each year. The 1099 SA is one of them. This IRS form tracks distributions from HSA, Archer MSA, and Medicare Advantage MSA accounts. If you also need to create pay stubs for your team, knowing these forms helps you stay compliant. Below, you will find what the form covers, what each box means, and how to handle it when filing your taxes. You will also learn how Form W-2 reporting fits in.

Key Takeaways

• Form 1099 SA reports distributions from HSA, Archer MSA, or Medicare Advantage MSA accounts
• Your HSA trustee sends it by January 31 each year
• Tax-free distributions cover qualified medical expenses; non-qualified ones trigger income tax plus a 20% tax penalty
• Report HSA distributions using Form 8889 with your Form 1040
• Employers must report HSA contributions in Form W-2 Box 12 using Code W

What Is a 1099 SA Form?

A 1099 SA form is an IRS tax document. It reports distributions from a Health Savings Account (HSA), Archer MSA, or Medicare Advantage MSA. Your HSA account trustee sends it by January 31 each year. It covers all withdrawals from the prior tax year.

The IRS uses this form to check whether account holders used their distributions for qualified medical expenses. Your HSA 1099 shows each withdrawal amount and type. You may also see it called a 1099 HSA form. Some people write it as 1099-HSA. These all refer to the same document.

Three types of accounts generate a 1099 SA for HSA and MSA holders:

• HSA: The most common type. Tied to high-deductible health plans
• Archer MSA: For self-employed people and small businesses
• Medicare Advantage MSA: Funded by Medicare

Your trustee or custodian files Form 1099 SA with the IRS and sends you a copy. If you offer an employer-sponsored HSA, each employee who took a distribution gets their own form. So what is a 1099-SA in simple terms? It is the receipt the IRS gets for every dollar leaving an HSA account. For a deeper look at how HSA contributions appear on tax documents, see our guide on where to find HSA contributions on your W-2.

When Do You Receive a 1099 SA?

You receive a 1099 SA by January 31 of the year after any withdrawal from your HSA or MSA. Every distribution triggers one. This includes debit card purchases and direct provider payments.

Common scenarios include paying a medical bill from your HSA account or using an HSA debit card. You will also get one if you removed excess contributions before April 15. Non-qualified expenses like non-medical purchases also count. If you are self-employed, you may also want to know how to report freelance income without a 1099.

If you are wondering what is 1099-SA form and why it matters, it gives the IRS a record of every HSA withdrawal you made. If your form has not arrived by mid-February, contact your HSA provider.

1099 SA Boxes Explained

Each box on the 1099 SA tax form reports details about your distributions.

Box	Label	What It Reports
1	Gross distribution	Total amount distributed during the tax year
2	Earnings on excess contributions	Earnings on excess contributions withdrawn
3	Distribution code	Code that shows the distribution type (see below)
4	Fair market value (FMV)	Account value on date of death (only if account holder died)
5	Account type checkbox	HSA, Archer MSA, or MA MSA

What is gross distribution? It is the total in Box 1. It shows every dollar paid out of your account. The HSA gross distribution meaning is simple. It covers debit card purchases and reimbursements. It does not include rollovers to another HSA or trustee-to-trustee transfers.

Box 3 Distribution Codes

Code	Meaning
1	Normal distribution (qualified medical expense)
2	Excess contributions removed
3	Disability
4	Death (distributed to estate or spouse)
5	Prohibited transaction
6	Death (distributed to non-spouse beneficiary)

Code 1 is the most common. Code 5 is a red flag. It means the HSA account was used in a prohibited transaction. This disqualifies the entire account. You can also learn about how FICA tax affects your take-home pay.

Qualified vs. Non-Qualified Distributions

The tax treatment of your HSA distribution depends on how you used the funds.

Qualified distributions are withdrawals for qualified medical expenses as defined by IRS Publication 969. These count as tax-free distributions. This is part of the HSA triple-tax advantage. Contributions lower taxable income. The balance grows tax-free. Qualified withdrawals avoid tax entirely.

Non-qualified distributions are withdrawals for non-qualified expenses. These get added to your taxable income. You also face a 20% tax penalty on top of regular income tax. If you are age 65 or older, or have a disability, the 20% penalty does not apply. Income tax still does. See how tax deductions work on a 1099 to plan ahead.

Excess contributions above the annual contribution limits trigger a 6% excise tax each year they remain. Pull out the excess by April 15 to stop the penalty. For 2026, HSA contribution limits are $4,400 (individual) and $8,750 (family), plus $1,000 catch-up for age 55+.

Used HSA funds for a non-qualified expense by mistake? Repay the amount by April 15 of the next year to avoid the penalty.

How to Report Your 1099 SA on Your Tax Return

You do not attach your 1099 SA to your tax return. Use the data to fill out the right form when filing your taxes:

• HSA holders: Transfer Box 1 to Form 8889, Line 14a. Enter qualified expenses on Line 15. If distributions exceed expenses, the gap flows to Line 17b. Attach Form 8889 to your Form 1040.
• MSA holders: Use Form 8853 instead of Form 8889.

A common mistake is thinking you need to include the 1099-SA tax form with your return. You do not. It is just reference material for Form 8889 or Form 8853. If you want to know what is Form 1099 SA compared to the Form W-2, our guide to W-2 forms explains the difference.

For a 1099-SA example, see the sample form on the IRS website. It shows how each box looks when filled in.

1099 SA and Employer Obligations: Form W-2 Box 12

If you offer an HSA plan, your duty is not the 1099 SA. The HSA trustee handles that. Your job is accurate Form W-2 reporting.

Report all HSA contributions in Box 12 of each employee's Form W-2 using Code W. This covers both pre-tax salary reductions and direct employer contributions. Financial institutions that file 250+ forms must follow IRS Publication 1220 for e-filing specs. For more on how payroll deductions appear on pay stubs, see our breakdown.

The HSA trustee reports distributions on the HSA form 1099-SA. You report contributions on the Form W-2. These are separate duties. Getting Box 12 wrong can trigger IRS scrutiny.
