What is Form 1099-SA?

Form 1099-SA reports money taken out of a health savings account (HSA), Archer MSA or Medicare Advantage MSA during the year. Whether that money is taxed depends on what it was spent on.

In shortForm 1099-SA is an IRS information return that reports distributions from a health savings account (HSA), an Archer Medical Savings Account or a Medicare Advantage Medical Savings Account. The account’s trustee or custodian, usually a bank or HSA provider, issues it to the account holder and the IRS, not the employer. Under 26 USC 223(f)(2), HSA distributions used for qualified medical expenses are not taxed, while amounts not used for them are included in gross income. Those taxable amounts generally carry an additional 20 percent tax, which does not apply after the account holder becomes disabled, dies, or reaches the Medicare eligibility age.

Who does what

Form 1099-SA roles
Who Role
HSA trustee or custodian Issues Form 1099-SA for the year’s distributions
Account holder (employee) Reports distributions on their tax return and keeps receipts
Employer Usually only offers the plan and sends contributions; does not file this form

Contributions to an HSA are reported on a different form, Form 5498-SA. Employers often get questions about both at tax time, so a short explainer for employees saves HR time.

Worked example: one qualified and one not

$1,200 out of an HSA

An employee, age 42, takes $1,200 out of her HSA during the year. $900 pays for qualified medical expenses: a dental procedure and prescriptions. She uses $300 for a non-medical expense.

Her Form 1099-SA shows a $1,200 gross distribution. On her return, the $900 used for qualified expenses is not taxed. The $300 is included in her income, and because she is under the Medicare eligibility age and not disabled, she also owes an additional 20 percent tax on it, $60.

If she had kept receipts showing the $300 was in fact for a qualified expense she forgot about, the result would have been different. That is why HSA providers tell account holders to keep receipts.

Mistakes that are specific to Form 1099-SA

What account holders should check on the form

  1. The gross distribution matches the total taken out of the account during the year, by card, transfer or check.
  2. The account type is correct: HSA, Archer MSA or Medicare Advantage MSA.
  3. Receipts are on hand for every qualified medical expense paid from the account.
  4. Any amount not used for qualified medical expenses is set aside to report as income on the return.
  5. Contributions are checked separately on Form 5498-SA, not on this form.

Employers can help without giving tax advice: tell employees which provider holds their HSA, when the provider usually sends tax forms, and where to find receipts and statements online. Questions about how a specific distribution is taxed belong with a tax professional.

Second example: after Medicare eligibility age

A long-serving employee, past the Medicare eligibility age, takes $2,000 from his HSA in the year. $1,400 goes to qualified medical expenses and $600 to a home repair.

His Form 1099-SA shows $2,000. The $1,400 is not taxed. The $600 is included in his income, but because he has reached the Medicare eligibility age, the additional 20 percent tax does not apply to it. Under age 65 and not disabled, the same $600 would also have carried $120 of additional tax.

Send a one-page explainer in JanuaryEach January, send employees with HSAs a short note: which form shows money in, which shows money out, who sends them, and to keep receipts. It answers most of the questions HR gets in February.
