Everything you need to know about filing 1099s, W-2s, and other tax forms for your business
Form 1099-SA is the IRS information return trustees and custodians use to report distributions from a Health Savings Account (HSA), Archer Medical Savings Account (MSA), or Medicare Advantage MSA. If you administer any of these accounts and money left the account during the tax year, you must file Form 1099-SA with the IRS and send a copy to each account holder.
Our platform makes 1099-SA eFiling fast, accurate, and IRS-compliant — even when you are reporting distributions across thousands of accounts.
Form 1099-SA — formally titled Distributions From an HSA, Archer MSA, or Medicare Advantage MSA — is the IRS information return that reports money withdrawn from a tax-advantaged health account during the year. You file one form for each account type that had a distribution.
Account holders use the information on Form 1099-SA to complete Form 8889 (for HSAs) or Form 8853 (for Archer and Medicare Advantage MSAs) on their federal tax return. The form tells them how much they took out, why it left the account, and whether any portion is taxable. Accurate reporting keeps your account holders from overpaying — and keeps your filings off the IRS correction list.
You must file Form 1099-SA if you are the trustee or custodian of a health account and a distribution was made during the tax year. This includes:
File a separate Form 1099-SA for each type of account. If an account holder took distributions from both an HSA and an Archer MSA, you file two forms. You also report distributions made to a beneficiary after the account holder’s death — the reporting differs depending on who the beneficiary is, so check the current IRS instructions before you file.
Note: A distribution is any money that leaves the account, including transfers, excess contribution withdrawals, and payments made directly to a provider. Report the full amount, then use the distribution code in Box 3 to explain the reason.
Collect the following before you file:
Validate every account holder’s TIN before you file. A mismatched name and SSN is the most common cause of a rejected return, and it is the easiest error to catch early. Run each recipient through TIN Matching first, then file with confidence.
Deadlines for Form 1099-SA are fixed. File on time to avoid penalties.
| Milestone | Deadline |
|---|---|
| Recipient copies furnished | January 31 of the year following the distribution |
| IRS paper filing | February 28 |
| IRS eFile submission | March 31 |
Filing threshold: If you file 10 or more information returns of any type in a calendar year, the IRS requires you to file electronically. eFiling meets that requirement and confirms receipt the moment you submit.
Penalties: Late or incorrect filings may result in penalties of $60–$310 per form, based on how late the correction is made. Intentional disregard penalties start at $660 per form with no cap. Filing accurate returns on time is the simplest way to avoid every one of these charges.
What is Form 1099-SA used for?
Form 1099-SA reports distributions from an HSA, Archer MSA, or Medicare Advantage MSA during the tax year. Account holders use it to complete Form 8889 or Form 8853 and figure out how much of their distribution is taxable.
Who is required to file Form 1099-SA?
The trustee or custodian of the account files it. This includes banks, credit unions, insurance companies, HSA administrators, and any financial institution that maintains these accounts and processed a distribution.
When is Form 1099-SA due?
Recipient copies are due by January 31. Paper filings with the IRS are due February 28, and eFile submissions are due March 31.
What’s the difference between Form 1099-SA and Form 5498-SA?
Form 1099-SA reports money that left the account — the distributions. Form 5498-SA reports money that went in — the contributions and the year-end fair market value. You file both for the same account, but they cover opposite sides of the activity.
Do I file a separate 1099-SA for each account type?
Yes. File one form per account type. If a holder took distributions from both an HSA and an Archer MSA, you file two separate 1099-SA forms.
What does the distribution code in Box 3 mean?
The code explains why the distribution happened — a normal distribution, an excess contribution withdrawal, a death or disability distribution, and so on. Choose the code that matches the reason, and check the current IRS instructions if you are unsure which applies.
How do I avoid a rejected 1099-SA filing?
Validate each account holder’s name and SSN before you submit. Mismatched taxpayer data is the leading cause of rejected returns. Running TIN Matching first catches these errors while you can still fix them.
What IRS penalties apply for missing or incorrect 1099-SA forms?
Penalties range from $60 to $310 per form depending on how late the correction is filed. Intentional disregard penalties start at $660 per form with no cap.
