If one arrives

Not taxable when spent on qualified medical expenses, reported on Form 8889.

The form is how a payer tells the IRS what it paid. Its absence is not permission — income you received is reportable whether or not a form covers it, and a threshold decides only who must file, never what you owe.

What it reports

The form's title names three accounts: "Distributions From an HSA, Archer MSA, or Medicare Advantage MSA." The trustee or custodian of the account files one for each type of account that paid money out during the year. It covers every withdrawal, whether the money went to you or "directly to a medical service provider." A debit card payment at the pharmacy is a distribution like any other.

The form reports what left the account. It says nothing about whether any of it is taxable: "You are not required to determine the taxable amount of a distribution." That is decided on your return.

The boxes

Box What it holds
1 Gross distribution: the total paid out during the year
3 Distribution code, which says what kind of payment it was
4 The account's fair market value on the date of death, where the holder died
5 Checkbox for the type of account: HSA, Archer MSA or MA MSA

Box 2, which concerns excess contributions returned to the holder, is not covered here.

The codes in box 3:

Code Meaning
1 Normal distribution, including direct payments to a provider
2 Excess contributions returned
3 Distribution after the holder became disabled
4 Death distribution to an estate
5 Prohibited transaction
6 Death distribution after the year of death to a beneficiary who is not the spouse

Most people see code 1.

Taxable or not

For an HSA the rule is short. Money spent on qualified medical expenses is tax-free, but it is still reported: Publication 969 says you "have to report the distribution on Form 8889." Money spent on anything else is income, and may carry an additional 20% tax, which does not apply after the holder dies, becomes disabled or reaches age 65. Box 1 is what left the account works through the calculation and the records you need to support it.

The proof is yours, not the trustee's. Keep the receipts that show what each withdrawal paid for, and that the same expense was not also paid from another source or deducted on Schedule A. Publication 969: "Don't send these records with your tax return. Keep them with your tax records."

What does not produce a form

  • A trustee-to-trustee transfer from one account to another of the same type.
  • A mistaken distribution that was returned, which the trustee must not report and must correct if it already has.

Common questions

My HSA debit card paid the doctor directly. Is that on the form?
Yes. The instructions: "The distribution may have been paid directly to a medical service provider or to the account holder." Direct payments are normal distributions, code 1, and are part of box 1.
I moved my account to another provider. Why is there no 1099-SA?
A direct transfer from one account to another of the same kind is not a distribution, and the instructions say not to report a trustee-to-trustee transfer.
The provider paid out money by mistake and I returned it. Is it on the form?
It should not be. The trustee is told: "Do not report the mistaken distribution on Form 1099-SA," and to correct a form already filed as soon as it learns of the error.
Does box 1 tell me how much is taxable?
No. The trustee is told: "You are not required to determine the taxable amount of a distribution." You decide it on Form 8889, from what each withdrawal paid for.
My parent's account passed to me. What will the form show?
The distribution in box 1, a death code in box 3, and in box 4 the account's fair market value on the date of death. A spouse who inherits it is treated differently from any other beneficiary, and the code shows which applies.
