If you took money out of a Health Savings Account, Archer MSA, or Medicare Advantage MSA last year, the account’s custodian is required to send you Form 1099-SA by January 31. To get your Form 1099-SA, log in to your custodian’s online portal and open the tax documents section, watch for the paper copy in the mail, or call the custodian’s customer service line if neither has appeared by early February. Contributions alone don’t trigger the form; you only receive one if a distribution was actually made during the year.
Who Sends the Form and When
The custodian or trustee that holds your account is the party responsible for issuing Form 1099-SA. If your HSA came through an employer, the custodian is usually a bank or benefits administrator named in your enrollment paperwork. For an account you opened on your own, it’s whichever institution you chose. If you’ve changed jobs and your former employer switched HSA providers along the way, check old benefits documents or contact the previous HR department to confirm who currently holds the account.
Custodians must provide the form to account holders by January 31 of the year following the distributions. A mailed form counts as timely if it’s postmarked by that date, so a copy that leaves the custodian on January 31 can still take a week or more to reach you.1Internal Revenue Service. General Instructions for Certain Information Returns (2025) The custodian’s separate deadlines for filing with the IRS (February 28 on paper, March 31 electronically) don’t affect when your copy arrives.
Three Ways to Get Your 1099-SA
Through the Custodian’s Online Portal
Most custodians post Form 1099-SA in a Tax Documents or Tax Center section of their secure portal. Log in, open that section, and pick the correct tax year. The PDF you download is identical to the paper version and is acceptable for filing. Electronic copies often appear several days before the paper version reaches the mailbox, so it’s worth checking the portal in mid-January.
If clicking the download link does nothing, check whether your browser is blocking pop-ups. Some banking dashboards require pop-ups to be allowed before a PDF will open.
By Mail
Unless you’ve affirmatively opted into electronic-only delivery, the custodian mails a paper copy to the address on file. Federal rules require custodians to obtain your written or electronic consent before they stop mailing paper forms, so if you never agreed to go paperless, a physical copy should arrive automatically. Make sure your mailing address is current with the custodian, especially if you’ve moved. Even if the account was closed during the year, the form still goes to the last address on record.
By Calling the Custodian
If the form hasn’t shown up online and hasn’t arrived in the mail by early February, call the custodian’s customer service line. They can confirm whether a distribution was even recorded (no distribution means no form was generated), resend the document, or walk you through downloading it from the portal. This is the fastest fix when something has gone wrong on their end.
What You Need to Log In and Download It
To access the form through the portal, you’ll need the username and password you set up when you opened the account. If you’ve forgotten them, most portals offer a reset process that verifies your identity with your Social Security number and other personal details. Your account number is typically printed on monthly statements or on the back of the debit card linked to the HSA, and many custodians also display it in the profile or settings section of their mobile app.
Gathering these details before mid-January keeps things from turning frantic once tax season opens.
If the Form Never Arrives or Looks Wrong
If the distribution amount on your 1099-SA doesn’t match your own records, contact the custodian’s customer service line or look for a correction request option in the online account. When the custodian confirms an error, they issue a corrected 1099-SA that replaces the original; you use the corrected version when filing.
If the form never arrived at all or was lost, the custodian can generate a duplicate through the portal or by mail. Digital duplicates are usually free. Some institutions charge a small fee to reprint and mail a paper copy.
One common misconception causes trouble here. Form 4852, the IRS substitute the agency provides when tax forms go missing, only works for W-2s and Form 1099-R.2Internal Revenue Service. Form 4852 (Rev. September 2020) It is not a valid substitute for a missing 1099-SA. If the custodian won’t cooperate and you cannot get the form, you still report your distributions on Form 8889 or Form 8853 using your own records: bank statements, withdrawal confirmations, and receipts. The IRS advises calling 800-829-1040 if you haven’t received a missing form by the end of February.3Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect
Don’t leave this until April. If you file with an incorrect distribution amount, the IRS will flag the mismatch between your return and what the custodian reported. Sorting corrections out early also prevents interest from accruing on any unpaid tax balance.
What the Boxes on Your 1099-SA Mean
Once you have the form in hand, the fields are straightforward:4Internal Revenue Service. Instructions for Forms 1099-SA and 5498-SA (12/2026)
- Box 1 shows the gross distribution: the total amount withdrawn during the year, including any earnings reported separately in Box 2.
- Box 2 shows earnings on excess contributions, filled in only if you over-contributed and pulled the excess out before your tax filing deadline.
- Box 3 is a single-digit distribution code. Code 1 is a normal distribution (including direct payments to doctors or pharmacies). Code 2 covers excess contributions returned. Code 3 is a distribution after disability. Codes 4 and 6 relate to distributions after the account holder’s death. Code 5 flags a prohibited transaction.
- Box 4 shows the fair market value on the date of death, filled in only if the account holder died during the year.
- Box 5 is a checkbox for the account type: HSA, Archer MSA, or Medicare Advantage MSA. That checkbox tells you which tax form to use when reporting.
The form does not break down what you spent the money on. It doesn’t distinguish between a dental bill and a grocery run. That burden is yours, which is why holding on to receipts matters.
What to Do With the Form Once You Have It
Receiving a 1099-SA doesn’t automatically mean you owe extra tax. It means you need to report the distribution and show whether the money went to qualified medical expenses. Which form you attach to your 1040 depends on the account type in Box 5.
If Box 5 shows an HSA, the Box 1 amount goes on line 14a of Form 8889 (Health Savings Accounts). You must file Form 8889 with your 1040 for any year your HSA made a distribution, even if you have no taxable income to report.5Internal Revenue Service. 2025 Instructions for Form 8889 Health Savings Accounts (HSAs)
If Box 5 shows an Archer MSA or Medicare Advantage MSA, the Box 1 amount goes on line 6a of Form 8853 instead. Like Form 8889, you must attach Form 8853 to your 1040 whenever distributions occurred during the year.6Internal Revenue Service. Instructions for Form 8853
