Form 1099-SA: Understanding Your HSA Distribution Form

What Form 1099-SA Is For

Form 1099-SA (Distributions From an HSA, Archer MSA, or Medicare Advantage MSA) is an official tax document that reports money you took out of your health savings account during the tax year. Think of it as your receipt showing that you withdrew funds from your medical savings account—whether you used that money to pay a doctor directly, bought prescription medications, or simply transferred the money to your personal bank account.

Your HSA trustee or custodian (typically a bank or insurance company) sends this form to both you and the IRS whenever you take a distribution. You'll receive it by January 31st following the tax year, and you'll need it when preparing your tax return. The form itself is straightforward, containing just a few boxes: Box 1 shows the total amount you withdrew, Box 2 reports any earnings on excess contributions that were returned, Box 3 contains a distribution code explaining what type of withdrawal it was, and Box 5 indicates which type of account the money came from (HSA, Archer MSA, or Medicare Advantage MSA).

The critical thing to understand is that Form 1099-SA is simply informational—it reports what happened but doesn't tell the IRS whether your distribution was taxable. That determination happens when you file Form 8889 with your tax return, where you'll explain how you used the money IRS.gov.

When You’d Use Form 1099-SA (Late/Amended)

Most taxpayers receive their Form 1099-SA on time and file accordingly. However, life doesn't always follow the IRS calendar, and you may need to file late or amend your return in several situations.

Late Filing Scenarios

If you didn't receive your Form 1099-SA before filing your tax return, you should still report your HSA distributions on Form 8889 using your own records. Once you receive the official form, verify that your reported amounts match. If you forgot to report HSA distributions entirely, you must file an amended return using Form 1040-X as soon as you discover the error—even if the distributions were for qualified medical expenses and wouldn't result in additional tax.

Amended Return Situations

You'll need to amend your 2022 tax return if you discover that you incorrectly reported distribution amounts, misclassified distributions as qualified medical expenses when they weren't, or failed to include the additional 20% penalty tax on non-qualified distributions. A common amendment scenario occurs when someone withdraws excess contributions after filing their original return. If you timely filed your return without withdrawing excess contributions, you can still make the withdrawal no later than 6 months after your tax return's due date (excluding extensions). When doing so, file an amended return with ""Filed pursuant to section 301.9100-2"" written at the top, including an explanation of the withdrawal IRS.gov.

Another situation requiring amendment involves mistaken distributions. If you withdrew money from your HSA believing an expense was qualified when it wasn't, and you repay it by April 18 following the first year you knew or should have known it was a mistake, the distribution isn't included in income and isn't subject to the 20% additional tax. Your trustee should correct the Form 1099-SA, but you may need to amend if you already filed IRS.gov.

Key Rules or Details for 2022

Several important rules governed HSA distributions in 2022, and understanding them helps you avoid costly mistakes.

Qualified Medical Expenses

The cornerstone of HSA tax benefits is that distributions used for qualified medical expenses aren't taxed. For 2022, qualified medical expenses generally include unreimbursed costs that would otherwise be deductible on Schedule A, covering expenses for you, your spouse, or your dependents. Importantly, expenses must be incurred after you established your HSA to qualify. Over-the-counter medicines (whether prescribed or not) and menstrual care products qualified as medical expenses for amounts paid after December 31, 2019. Additionally, personal protective equipment like masks and hand sanitizer, plus the cost of home COVID-19 testing, were eligible medical expenses that could be reimbursed tax-free from an HSA in 2022 IRS.gov.

The 20% Penalty

Any HSA distribution not used for qualified medical expenses is included in your gross income and subject to an additional 20% tax. However, three exceptions exist: distributions made after you turn 65, after you become disabled (as defined under IRS rules), or after death. If any exception applies, you only report the distribution as income without the 20% penalty IRS.gov.

Distribution Codes Matter

Box 3 of Form 1099-SA contains a distribution code that's crucial for proper reporting. Code 1 indicates normal distributions (the most common), Code 2 shows excess contributions being returned, Code 3 means you were disabled when the distribution occurred, Code 4 indicates a death distribution to an estate, and Code 6 shows a death distribution to a non-spouse beneficiary after the year of death. Understanding your code helps you complete Form 8889 correctly IRS.gov.

No Need to Prove to the IRS

You don't need to submit receipts or documentation with your tax return proving your distributions were for qualified expenses. However, you absolutely should keep detailed records—receipts, invoices, and explanations of benefits—because the IRS can audit you and request this documentation later. The burden of proof is on you IRS.gov.

Step-by-Step (High Level)

Handling Form 1099-SA correctly involves a logical sequence of steps that ensure accurate tax reporting.

Step 1—Receive and Review

By January 31, 2023, you should receive Form 1099-SA from your HSA trustee. Immediately verify that the information is accurate: confirm your name, Social Security number, and address are correct, check that Box 1 matches your records of total distributions, and verify the account type checkbox in Box 5 is correct.

Step 2—Gather Your Records

Before preparing your tax return, compile documentation for all medical expenses you paid with HSA funds during 2022. This includes receipts, invoices, explanation of benefits statements from insurance, and any correspondence about medical treatments. Organize these by date and total them up—this becomes the amount you'll report on Form 8889, Line 15.

Step 3—Complete Form 8889

This is the critical form where you reconcile your HSA activity. You must file Form 8889 if you (or anyone on your behalf) made contributions to your HSA, if you received HSA distributions, or if you're subject to testing period rules from prior years. On Part II of Form 8889, enter your total distributions from Form 1099-SA Box 1 on Line 14a, report any rollovers or returned excess contributions on Line 14b, and enter your qualified medical expenses on Line 15. The form calculates your taxable distribution (Line 16) and any 20% additional tax owed (Line 17b).

Step 4—Transfer to Your Tax Return

Report your HSA deduction (from Form 8889, Line 13) on Schedule 1 (Form 1040), Line 13. If you have taxable distributions or additional taxes from Form 8889, these flow to Schedule 1 as other income and to Schedule 2 for additional taxes. Attach Form 8889 to your Form 1040, 1040-SR, or 1040-NR IRS.gov.

Step 5—Keep Everything

After filing, retain your Form 1099-SA, Form 8889, and all supporting medical expense documentation for at least three years (the standard IRS audit period), though keeping records longer is wise. If the IRS questions your distributions, you'll need these records to prove the money went to qualified expenses.

Common Mistakes and How to Avoid Them

Even conscientious taxpayers make errors with Form 1099-SA. Here are the most frequent mistakes and strategies to prevent them.

Mistake #1: Forgetting to File Form 8889

Some people receive Form 1099-SA, see that they used all the money for medical expenses, and assume they don't need to report anything. Wrong. You must file Form 8889 whenever you receive HSA distributions, even if every penny went to qualified expenses and you owe no tax. Solution: Treat Form 8889 as a mandatory companion to Form 1099-SA—if you get one, you must file the other.

Mistake #2: Claiming Non-Qualified Expenses

Not every health-related expense qualifies. Insurance premiums generally don't qualify (except for long-term care insurance, COBRA, healthcare while receiving unemployment benefits, or Medicare premiums if you're 65 or older). Cosmetic procedures, general wellness items, and vitamins typically don't qualify unless prescribed for a specific medical condition. Solution: Before taking a distribution, consult IRS Publication 502 (Medical and Dental Expenses) to verify the expense qualifies.

Mistake #3: Using Distributions for Pre-HSA Expenses

You can only use HSA funds tax-free for expenses incurred after you established the account. If you opened your HSA in June 2022, you cannot tax-free reimburse yourself for medical bills from March 2022. Solution: Mark your HSA establishment date clearly in your records and only reimburse expenses from that date forward IRS.gov.

Mistake #4: Inadequate Record-Keeping

Taking distributions without maintaining receipts and documentation is a recipe for disaster during an audit. Simply having bank statements showing you paid a medical provider isn't enough—you need to prove the expense was qualified and not reimbursed by insurance. Solution: Create a simple filing system where you immediately file receipts when you take HSA distributions, note the date, provider, service, and amount on each receipt.

Mistake #5: Misunderstanding the Testing Period

If you qualified for HSA contributions under the ""last-month rule"" in 2021, you must remain an eligible individual throughout 2022 or face income inclusion and a 10% penalty on contributions that wouldn't have been allowed otherwise. Similarly, if you made a qualified HSA funding distribution from an IRA to your HSA, failing to remain eligible during the 12-month testing period triggers income inclusion and a 10% penalty. Solution: If you used the last-month rule or made an IRA-to-HSA rollover, calendar a reminder to verify your continued eligibility at the end of the testing period IRS.gov.

What Happens After You File

Once you've filed your tax return with Form 8889 attached, several things occur behind the scenes.

IRS Matching

The IRS receives a copy of your Form 1099-SA directly from your HSA trustee. Their computers automatically match the information on your trustee's form against what you reported on Form 8889. If the amounts match and your return is otherwise unremarkable, your return processes normally, and you'll receive any refund or get billed for any balance due according to normal IRS timelines.

Potential for Inquiry

If discrepancies exist between your Form 1099-SA and your Form 8889, the IRS may send a letter asking you to explain the difference. Common discrepancies include reporting a different distribution amount than shown on Form 1099-SA, or claiming a rollover or excess contribution withdrawal that the trustee didn't report as such. Usually, these are resolved by sending documentation proving your position.

Audit Possibilities

HSA distributions are an audit risk area because the IRS has no way of verifying whether your distributions actually paid for qualified medical expenses. If selected for audit, you'll receive a letter requesting documentation proving the expenses were qualified, paid during the year claimed, not reimbursed by insurance, and incurred after your HSA was established. This is why meticulous record-keeping is essential. If you cannot substantiate the expenses, the IRS will treat the distributions as taxable income, assess the 20% additional tax (unless an exception applies), and charge interest from the original due date of the return.

State Tax Considerations

Most states follow federal HSA rules, so if your distribution was tax-free federally, it's also tax-free at the state level. However, California and New Jersey don't conform to federal HSA rules—residents of these states must pay state income tax on HSA earnings and may face different treatment of distributions. Always check your specific state's rules.

FAQs

1. I received Form 1099-SA but used all the money for medical expenses. Do I still need to report it?

Yes, absolutely. You must file Form 8889 with your tax return whenever you receive any HSA distribution, regardless of how you used the money. Form 8889 is where you tell the IRS that your distributions went to qualified medical expenses and therefore shouldn't be taxed. Failing to file Form 8889 may result in the IRS treating your entire distribution as taxable income plus assessing the 20% penalty.

2. Can I reimburse myself years later for old medical expenses?

Yes, as long as the expenses were incurred after you established your HSA. There's no time limit for reimbursing yourself. If you opened your HSA in 2018 and had qualified medical expenses that year which you paid out-of-pocket, you can reimburse yourself in 2022 tax-free—but keep excellent records proving when the expense occurred and that it wasn't previously reimbursed IRS.gov.

3. What if I made a mistake and used HSA money for non-qualified expenses?

You must report that distribution as taxable income on Form 8889, Line 16, and pay the 20% additional tax on Line 17b unless you qualify for an exception (age 65+, disabled, or deceased). There's no way to ""fix"" this by later paying for qualified expenses—each distribution stands on its own based on how the money was actually used. Consider it an expensive lesson and be more careful going forward.

4. My Form 1099-SA shows a distribution, but it was actually a trustee-to-trustee transfer to another HSA. What do I do?

Trustee-to-trustee transfers between HSAs shouldn't be reported on Form 1099-SA at all. Contact your HSA trustee immediately and request a corrected Form 1099-SA showing zero distribution. If your trustee incorrectly reported it as a distribution, they need to file a corrected form with the IRS. Once corrected, you won't report it as a distribution on your Form 8889 IRS.gov.

5. I turned 65 mid-year and enrolled in Medicare. How does this affect my HSA?

Once you enroll in Medicare, you can no longer contribute to your HSA, and your contribution limit for the year is prorated based on how many months you were eligible before Medicare started. However, you can still take tax-free distributions for qualified medical expenses forever—your HSA doesn't close, and the funds remain available throughout your life. The age-65 exception means that even if you take distributions for non-medical expenses after turning 65, you won't pay the 20% penalty (though you'll still pay regular income tax on non-qualified distributions) IRS.gov.

6. What happens if I made excess HSA contributions and need to withdraw them?

You can withdraw excess contributions (and any earnings on them) by the due date of your tax return, including extensions, without paying the 6% excise tax on excess contributions. However, you must include the earnings portion as ""Other income"" on your tax return. Report the withdrawal on Form 8889, Line 14b. If you miss the deadline, you'll pay a 6% excise tax annually using Form 5329 until the excess is corrected IRS.gov.

7. Do I need to keep receipts for HSA distributions forever?

While the IRS statute of limitations is generally three years, keeping HSA-related receipts for longer is advisable. Because you can reimburse yourself years later for old expenses, maintaining permanent records helps prove both that old expenses remain unreimbursed (and thus eligible for future distribution) and that current distributions correspond to legitimate qualified expenses. At minimum, keep receipts for six years after the distribution.
