You maxed out your HSA contributions last year, kept every receipt, and filed on time. Then a form arrives in May with numbers that do not match what you reported in April. Or you withdrew funds for an expense you assumed was covered, only to find out later it was not, and now you owe both income tax and a 20% penalty on money you already spent. Form 5498-SA is a one-page informational form, but what it reports, and whether it matches your records, has real consequences at filing time.
This guide covers every term, box, and deadline on Form 5498-SA so you know exactly what your trustee is reporting to the IRS, what to do if something looks wrong, and how to avoid the penalty situations that catch most people off guard.
Managing HSA reporting correctly is one of those details that looks simple until it is not. Simplicity Financial’s tax preparation services are available entirely online, working with individuals, self-employed professionals, and small business owners across California and nationwide to make sure every form is filed accurately and every contribution is accounted for.
What is Form 5498-SA?
Form 5498-SA is an IRS informational return that reports contributions made to a Health Savings Account (HSA), Archer MSA, or Medicare Advantage MSA during the tax year. Your bank, brokerage, or insurance company, called the trustee or custodian, prepares and issues this form. A copy goes to you, and a copy goes directly to the IRS.
The IRS uses this form to verify that contributions to your account were within the legal limits. You use it as a reference document, primarily to complete Form 8889 when filing your federal return.
One important clarification: Form 5498-SA is not attached to your tax return. Think of it the way you would a year-end account summary. It is informational, not something you submit. If you receive pension or annuity payments alongside HSA contributions, Form W-4P is a related form worth reviewing as part of your annual filing picture.
Key Terms Defined: HSA, Archer MSA, and Medicare Advantage MSA
Form 5498-SA covers three distinct account types, each with different rules, eligibility requirements, and contribution structures.
1. HSA (Health Savings Account)
An HSA is a tax-advantaged savings account available to individuals enrolled in a High-Deductible Health Plan (HDHP). Contributions are tax-deductible, the account grows tax-free, and withdrawals for qualified medical expenses are also tax-free. This is often called the triple tax advantage. Both you and your employer can contribute to an HSA, though total contributions from all sources cannot exceed the annual IRS limit. HSAs are portable, meaning they stay with you even if you change jobs.
2. Archer MSA
An Archer MSA is an older account type, largely replaced by HSAs. It was designed for self-employed individuals and employees of small businesses, generally those with 50 or fewer employees, enrolled in an HDHP. Contribution limits for an Archer MSA are calculated as a percentage of your annual deductible, which differs from the flat-dollar HSA limits. If you have an Archer MSA, it will appear on Box 1 of your Form 5498-SA.
3. Medicare Advantage MSA (MA MSA)
A Medicare Advantage MSA is funded entirely by Medicare. The account holder cannot make personal contributions. It is paired with a high-deductible Medicare Advantage plan. Medicare deposits a set amount into your account each year, and you use those funds for qualified medical expenses before your deductible is met. If you hold this account type, Box 6 of your Form 5498-SA will reflect the MA MSA designation.
Form 5498-SA Box-by-Box Field Glossary
Each box on Form 5498-SA captures a specific category of contribution or account data. The table below defines each field and notes where it flows on your tax return. For a broader look at how informational returns work, see our guide on reporting 1099 forms.
| Box | Description | Notes |
| Box 1 | Archer MSA contributions made by you or your employer | Flows to Form 8889, Part I |
| Box 2 | Total HSA contributions for the year, including employer contributions and any Qualified HSA Funding Distribution (QHFD) from an IRA | Flows to Form 8889, Line 2; QHFD is a one-time IRA-to-HSA transfer |
| Box 3 | Contributions made in the current year for the prior tax year | Applies to contributions made Jan. 1 through Apr. 15 designated for the previous year |
| Box 4 | Rollover contributions from another HSA or Archer MSA | Not counted toward your annual contribution limit |
| Box 5 | Fair market value of the account on December 31 | Informational; used for IRS reconciliation |
| Box 6 | Account type checkbox | Indicates whether the account is an HSA, Archer MSA, or MA MSA |
According to the IRS Instructions for Forms 1099-SA and 5498-SA, Form 5498-SA reports all contributions to your HSA for the prior year, including those contributed between January 1 and the tax filing deadline. This makes it a critical document for accurate tax reporting and IRS reconciliation.
Box 3 is especially worth watching. If you contributed to your HSA between January 1 and April 15 and designated those funds for the prior tax year, they may not appear on a January-issued form. A corrected or supplemental form may arrive later.
Contribution Limits, Catch-Up Rules, and the Last Month Rule
Knowing the annual limits helps you verify that what appears on your Form 5498-SA reflects accurate and complete contribution reporting. The IRS sets annual caps that apply across all accounts you hold.
| Year | Individual Coverage | Family Coverage | Catch-Up (Age 55+) |
| 2025 | $4,300 | $8,300 | +$1,000 |
| 2026 | $4,400 | $8,750 | +$1,000 |
The catch-up contribution allows individuals age 55 or older to add an extra $1,000 per year, regardless of whether you have individual or family coverage.
The Last Month Rule is worth understanding if your HDHP enrollment did not start on January 1. If you are enrolled in an HDHP on December 1 of the tax year, the IRS treats you as having been eligible for the entire year. This lets you contribute the full annual limit even if you were only enrolled for part of the year.
The catch is the testing period. You must remain enrolled in an HDHP through December 31 of the following year. If you do not, any excess contribution claimed under this rule becomes taxable income and is subject to a 10% penalty.
A quick example: someone who enrolled in an HDHP in September 2026 can contribute the full $4,400 individual limit for 2026 under the Last Month Rule, but must stay enrolled through December 31, 2027. Form 8889 is where these limits are enforced when you file your return.
Excess Contributions and Non-Qualified Distributions: Penalties Defined
Two penalty categories catch many HSA holders off guard. Both are avoidable, but only if you know the rules before you hit them.
Excess contributions
This happens when your total HSA contributions for the year go over the IRS annual limit. The penalty is a 6% excise tax on the amount over the limit, and it is not a one-time charge. It repeats every year the excess stays in the account.
The fix is straightforward: withdraw the excess amount plus any earnings it generated before your tax filing deadline, extensions included. Miss that window and the excess rolls forward, triggering the 6% penalty again the following year.
Non-qualified distributions
This happens when you use HSA funds for something the IRS does not consider a qualified medical expense under IRS Publication 502. The withdrawn amount becomes taxable income, and a 20% penalty is added on top.
A straightforward example: you withdraw $500 from your HSA to cover a gym membership. That $500 is added to your taxable income for the year, and you owe an additional $100 penalty. One expense the IRS does not recognize costs you twice.
The exception: after age 65, or in the case of death or disability, the 20% penalty is waived. You will still owe income tax on the withdrawal, but the penalty does not apply.
These are exactly the kinds of details that surface during a thorough tax review and go unnoticed without one.

Common Form 5498-SA Errors and How to Correct Them
Errors on Form 5498-SA do happen, and knowing what to look for can save you from filing a return based on incorrect information.
1. Wrong TIN or Social Security Number
Contact your trustee immediately. They are responsible for filing a corrected form with the IRS. Do not attempt to alter the form yourself.
2. Missing contributions
If you made a contribution between January 1 and April 15 for the prior tax year, it may not appear on a form issued in January or February. Trustees sometimes issue a supplemental or corrected Form 5498-SA after April 15 to capture these. This is normal. Track your own contributions so you are not caught off guard.
3. Duplicate forms from multiple accounts
If you held HSAs with two different providers during the year, you will receive a separate Form 5498-SA from each. The key is making sure your total contributions across both accounts do not exceed the annual IRS limit. Each form reports only what that trustee received.
4. Employer contributions reported incorrectly
Employer contributions to your HSA should also appear on your W-2 in Box 12 with Code W. If they are missing from the W-2 or appear only on the Form 5498-SA, contact your payroll department for a corrected W-2.
5. How to request a correction
Always contact the issuing trustee or custodian to request an amended Form 5498-SA. If the error affected a return you have already filed, a Form 1040-X may be required to correct it. Errors are more common when you have changed employers mid-year or held accounts at multiple institutions simultaneously. See our guide on amending tax returns for a full walkthrough of that process.
When You Will Receive Form 5498-SA and What to Do With It
Trustees are required to issue Form 5498-SA by May 31 of the year following the tax year. This is intentionally after the April 15 tax filing deadline, and the timing gap is by design.
Because HSA contributions can be made up to April 15 for the prior tax year, the final contribution total is not known until that date passes. Trustees need time to capture any last-minute contributions before preparing the form.
This means that when you file by April 15, you are working from your own contribution records, not from a finalized Form 5498-SA. You report your contributions on Form 8889 based on what you know. When the form arrives in May, compare it to what you reported. If there is a discrepancy, an amended return may be needed, though this is uncommon if you have tracked contributions carefully throughout the year.
Some trustees issue a preliminary form in January if they do not expect any prior-year contributions after January 1. The form is sent both to you and directly to the IRS. You never mail or attach it to your federal return.
Frequently Asked Questions About Form 5498-SA
Do I need to attach Form 5498-SA to my tax return?
No. Form 5498-SA is an informational document. You use it to verify your contribution records and complete Form 8889, but it is never attached to or submitted with your federal return.
What if my Form 5498-SA arrives after I have already filed?
This is expected. Trustees are not required to issue the form until May 31, which is after the April 15 filing deadline. Compare the form to what you reported on Form 8889. If there is a discrepancy, an amended return may be needed.
Who issues Form 5498-SA?
Your HSA trustee or custodian, typically your bank, brokerage, or insurance company, prepares and issues the form. You do not request it. It is sent to you and directly to the IRS automatically.
