If you've received a Form 1099-SA in the mail, you might be wondering what it means for your taxes and whether you need to worry. The good news is that this form is actually pretty straightforward once you understand what it's tracking.
What Is Form 1099-SA?
Form 1099-SA is a tax document that reports distributions (withdrawals) you made from certain tax-advantaged health accounts during the year. The "SA" stands for "Distributions From an HSA, Archer MSA, or Medicare Advantage MSA."
Think of it as a receipt from your account administrator showing how much money you took out of your health savings account. Your financial institution or plan administrator is required to send you this form and send a copy to the IRS whenever you withdraw money from one of these accounts.
The three types of accounts that trigger a 1099-SA are:
Health Savings Accounts (HSAs)
These are the most common type. HSAs are available to people with high-deductible health plans and offer triple tax advantages: tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses.
Archer Medical Savings Accounts (Archer MSAs)
These are older accounts that are no longer widely available. They were predecessors to HSAs and work similarly, though they're limited to self-employed individuals and employees of small businesses.
Medicare Advantage MSAs
These specialized accounts are paired with certain high-deductible Medicare Advantage plans and work somewhat like HSAs but for Medicare beneficiaries.
Why Does This Form Matter?
The IRS needs to know about your distributions because the tax treatment depends on how you used the money. If you spent the funds on qualified medical expenses, those distributions are typically tax-free. However, if you used the money for non-medical purposes, you'll generally owe income tax on the distribution and possibly a penalty.
Form 1099-SA helps both you and the IRS keep track of the total amount you withdrew, which you'll need to report on your tax return. The form itself doesn't tell the IRS whether your expenses were qualified or not — that part is up to you to figure out and report correctly.
Breaking Down the Form: What Each Box Means
Box 1: Gross Distribution
This is the total amount you withdrew from your account during the year. It's the most important number on the form and the one you'll reference when preparing your taxes. This includes all distributions, regardless of what you used them for.
Box 2: Earnings on Excess Contributions
This box is usually blank for most people. It only shows an amount if you contributed more than the legal limit to your account and then withdrew those excess contributions plus any earnings they generated. The number here represents just the earnings portion, which is taxable.
Box 3: Distribution Code
This single-digit code identifies what type of account your distribution came from. Code 1 means it's from an HSA, Code 2 indicates an Archer MSA, Code 3 is for a Medicare Advantage MSA, and Code 4 means it's from a combination of these account types.
Box 4: FMV on Date of Death
This box only applies in the unfortunate event that the account holder passed away. It shows the fair market value of the account on the date of death, which matters for estate and inheritance purposes.
Box 5: Account Holder Information
This checkbox tells you whose account this is. If it's checked, the distributions were made by someone other than the account holder — typically a beneficiary who inherited the account.

When Will You Receive Form 1099-SA?
Your plan administrator must send you Form 1099-SA by Monday, February 2nd, 2026 if you made any distributions during the previous calendar year. So if you took money out of your HSA anytime in 2025, you should receive the form by Monday, February 2nd, 2026.
You'll get this form in addition to Form 5498-SA, which reports your contributions to the account. While the 5498-SA shows money going in, the 1099-SA shows money coming out. Together, these forms give a complete picture of your account activity.
What to Do When You Receive Your 1099-SA
First, check that all the information is correct. Make sure your name, address, and Social Security number are accurate, and verify that the distribution amount in Box 1 matches your records. If you spot any errors, contact your plan administrator right away to get a corrected form.
Next, gather documentation for all the expenses you paid with your distributions. This means collecting receipts, invoices, and explanation of benefits statements from your insurance company. Most tax professionals recommend keeping these records for at least three years.
When tax time arrives, you'll report your 1099-SA distribution on Form 8889 (for HSAs) or Form 8853 (for Archer MSAs or Medicare Advantage MSAs).
Understanding Qualified Medical Expenses
The key to avoiding taxes and penalties on your distributions is making sure you used the funds for qualified medical expenses.
Generally speaking, qualified medical expenses are costs that would be deductible as medical expenses on Schedule A if you were itemizing deductions. This includes a wide range of healthcare-related spending, such as doctor visits, prescription medications, dental care, vision care, hospital services, medical equipment, and even some over-the-counter medications and menstrual care products.
Some expenses that might surprise you as qualified include acupuncture, chiropractic care, hearing aids, prescription eyeglasses and contacts, smoking cessation programs, and even mileage to and from medical appointments.
However, not everything health-related qualifies. You generally cannot use HSA funds tax-free for health insurance premiums (with some exceptions), cosmetic procedures, gym memberships or fitness programs, or vitamins and supplements unless prescribed by a doctor for a specific medical condition.
What Happens If You Used the Money for Non-Qualified Expenses?
Life happens, and sometimes people withdraw money from their HSA for non-medical purposes. What are the consequences?
If you're under age 65 and use HSA funds for non-qualified expenses, you'll face a double penalty. First, the distribution will be included in your taxable income, meaning you'll pay your regular income tax rate on that amount. Second, you'll owe an additional 20% penalty tax on top of the regular income tax. So if you're in the 22% tax bracket and withdraw $1,000 for non-qualified expenses, you'd owe $220 in regular taxes plus $200 as a penalty — a total of $420.
Once you turn 65, the rules become more lenient. You'll still owe income tax on non-qualified distributions, but the 20% penalty no longer applies. This makes HSAs function somewhat like traditional IRAs after age 65.
Special Situations and Considerations
Mistaken Distributions
If you accidentally withdrew money for a non-qualified expense and then realized your mistake, you might be able to fix it. If you return the funds to your HSA by the tax filing deadline (including extensions), you can treat the distribution as a rollover in some cases.
Reimbursing Past Expenses
One of the unique features of HSAs is that you can reimburse yourself for qualified medical expenses years after you paid them out of pocket, as long as the expense was incurred after you established the HSA. The key is keeping excellent records.
Multiple HSAs
If you have more than one HSA, you'll receive a separate Form 1099-SA for each account that had distributions. You'll need to combine all these distributions when reporting on your tax return.
Death of Account Holder
When an HSA owner passes away, the treatment depends on who inherits it. If the beneficiary is a spouse, they can treat the HSA as their own and continue using it tax-free for qualified medical expenses. For non-spouse beneficiaries, the entire account becomes taxable as income in the year of death.
Common Mistakes to Avoid
- Don't assume all distributions are tax-free just because they came from an HSA — you still need to report the distribution and prove (if audited) that the expenses were qualified.
- Keep detailed records even if you only use your HSA for qualified expenses.
- Remember that over-the-counter medications generally require a prescription to be qualified expenses, with some exceptions.
- Be careful about mixing up contributions and distributions. Form 5498-SA reports contributions, while Form 1099-SA reports distributions.
