Form 5498-SA + AI Agent Skill: HSA Information Reporting Guide 2026

Form 5498-SA is the information return your HSA custodian files to report the contributions that went into your Health Savings Account. You do not file it, attach it, or report it on your tax return. The custodian sends one copy to the IRS and one copy to you, and your only job is to reconcile it against the Form 8889 you already filed. It arrives by May 31, after the April deadline, which is why most filers never open the envelope.

Key takeaways:

• Your HSA custodian (Fidelity, Lively, HealthEquity, Optum Bank, HSA Bank) files Form 5498-SA. You do not.
• You never attach Form 5498-SA to your return. It is informational; you reconcile it against Form 8889 (contributions on Lines 2 and 9).
• Box 2 = total HSA contributions the custodian received during the calendar year. Box 3 = contributions made January 1 to April 15 and designated for the prior year.
• Deadline: the custodian both files with the IRS and furnishes your copy by May 31.
• A prior-year contribution lands on the following year's form in Box 3, so reconcile two consecutive 5498-SAs when you contribute in the January-to-April window.

Unlike Form 8889, which the account holder files, Form 5498-SA is filed by the HSA custodian: Fidelity, Lively, HealthEquity, Optum, or whoever holds your account. The custodian sends one copy to the IRS and one to you. The form arrives by May 31 of the year following the contribution year, which is why most filers never see it before they file. April 15 comes first.

What Is Form 5498-SA?

Form 5498-SA (officially "HSA, Archer MSA, or Medicare Advantage MSA Information") is the information return your HSA custodian files with the IRS to report contributions made to your account during the prior calendar year. The custodian is the filer; you are the recipient.

The form has six numbered boxes, but the central facts it reports are: how much went into the account during the year, how much went in via rollover, the year-end fair market value of the account, and the type of account (HSA, Archer MSA, or Medicare Advantage MSA).

Legal Basis: IRC §223(h) requires HSA trustees and custodians to report contribution information. IRC §220(h) governs the parallel reporting for Archer MSAs (a predecessor program now closed to new enrollees). IRS Publication 969 (Health Savings Accounts and Other Tax-Favored Health Plans) is the consumer-facing reference.

Who Receives Form 5498-SA?

You receive Form 5498-SA if any of the following happened during the tax year:

• You (or anyone on your behalf) made a contribution to your HSA
• Your employer made an HSA contribution on your behalf (including cafeteria plan contributions)
• You rolled funds from one HSA to another
• You executed a one-time qualified HSA funding distribution from an IRA
• The custodian held a balance in your HSA at year-end (Box 5, fair market value, is reported even if no contributions were made)

Who Skips Form 5498-SA?

• People who never opened an HSA
• Account holders who closed their HSA before year-end with a zero balance and made no contributions during the year
• Filers reporting Form 8853 for an Archer MSA (different form family, though 5498-SA does cover Archer MSAs)

If your spouse has a separate HSA, each spouse receives a separate Form 5498-SA for their own account. The custodian does not combine spousal HSAs.

You Don't File Form 5498-SA: You Reconcile It

This is the single most important sentence in this guide. You do not file Form 5498-SA. Your HSA custodian files it with the IRS, and they send you a copy for your records.

What you actually do with 5498-SA:

1. Receive it by May 31 of the year following the contribution year (e.g., 5498-SA for 2025 contributions arrives by May 31, 2026)
2. Compare the contribution figures against what you already reported on Form 8889 in April
3. Reconcile any discrepancies — contact the custodian if their numbers are wrong, or amend Form 8889 (via Form 1040-X) if your numbers were wrong
4. File it away: keep the document with your tax records for at least three years (six years if you under-reported income by more than 25%, indefinitely for any year with potentially fraudulent activity)

Because 5498-SA arrives after the April filing deadline, most filers complete Form 8889 from memory or from the year-end statement issued in January. The May 5498-SA is the truth check that comes too late to be useful unless you actively look at it.

Form 5498-SA Box-by-Box Walkthrough

The form has a header (custodian and recipient information) and six numbered boxes. Each one carries a specific meaning that the IRS cross-checks against your Form 8889.

Header: Identifying Information

The top of the form lists:

• Trustee/custodian name and TIN: Fidelity, Lively, HealthEquity, Optum Bank, HSA Bank, etc., with their employer identification number
• Recipient name, address, and SSN: you
• Account number: the custodian's internal HSA account identifier

Verify your name, address, and SSN are correct. A wrong SSN means the IRS cannot match the contribution to your return, which can trigger a notice claiming you under-reported HSA contributions on Form 8889. Contact the custodian immediately if any header field is wrong.

Box 1: Employee or Self-Employed Person's Archer MSA Contributions

For an Archer MSA only — the contributions made by the account holder (or their employer for self-employed Archer MSAs) during the tax year.

For HSAs, Box 1 is blank. Most filers in 2026 do not have an Archer MSA. If you do, see Form 8853 (separate form), not Form 8889.

Box 2: Total Contributions Made in the Current Year

The total HSA contributions made during the calendar year, including:

• Direct contributions (by check, transfer, or ACH from your bank)
• Cafeteria plan / Section 125 contributions routed through payroll
• Employer-only contributions (those the employer made without payroll withholding)
• Contributions made on your behalf by a family member

Excludes: rollovers (those go in Box 4), the qualified HSA funding distribution from an IRA (that's a Box 2 entry but distinguished by Box 6 designations in some custodian implementations — check your statement), and earnings inside the HSA.

Important timing nuance: Box 2 covers contributions received by the custodian during the calendar year. So a January 2026 contribution that the custodian credits as a 2025 prior-year contribution lands on the 2026 Form 5498-SA, not the 2025 form. This is the most common reconciliation headache and is described in detail below.

Sanity-check Box 2 against the annual limit. The HSA contribution limit is $4,300 self-only / $8,550 family for 2025 and $4,400 / $8,750 for 2026 (Rev. Proc. 2025-19), plus a $1,000 catch-up at age 55 or older. If Box 2 plus the prior-year Box 3 exceeds your limit for that tax year, you have an excess contribution to correct on Form 5329.

Box 3: Total HSA or Archer MSA Contributions Made in the Following Year for the Current Year

Contributions made between January 1 and April 15 of the year following the tax year, designated as prior-year contributions.

Example: You contribute $1,000 to your HSA on March 15, 2026, and tell the custodian (via their online form or paper election) that this contribution is for tax year 2025. That $1,000 lands on your 2026 Form 5498-SA Box 3, but you may deduct it on your 2025 Form 8889.

This box exists because the IRS needs to track prior-year-designated contributions separately from current-year contributions to validate Form 8889 line entries.

Box 4: Rollover Contributions

Rollovers from another HSA, Archer MSA, or (in the case of a qualified HSA funding distribution) from an IRA. Rollovers are not deductible — they are tax-free transfers — so they appear in Box 4 separately from Box 2 to avoid double-counting on Form 8889.

A taxpayer is allowed only one HSA-to-HSA rollover per 12-month period under IRC §223(f)(5). Custodian-to-custodian transfers do not count against this limit (they are not rollovers in the legal sense), but indirect rollovers (where money flows through the account holder) do.

Box 5: Fair Market Value of HSA, Archer MSA, or Medicare Advantage MSA

The total balance in the account on December 31 of the tax year — including cash, mutual funds, ETFs, and any other invested assets at their year-end market value.

Box 5 has a few practical uses:

• The IRS uses it to flag accounts with potential excess contributions (if Box 5 grows by far more than Box 2 + Box 4, the IRS wonders why)
• Your future self uses it as a baseline when comparing how the HSA is growing
• Estate planners use it for net-worth reporting
• Underwriters use it as proof of liquid assets for mortgage and loan applications

Box 5 is informational. It does not flow to any Form 8889 line directly.

Box 6: Type of Account

A check-box indicating which account type the form covers:

• HSA: Health Savings Account (IRC §223)
• Archer MSA: Archer Medical Savings Account (IRC §220, closed to new enrollees since 2007)
• Medicare Advantage MSA: for Medicare beneficiaries enrolled in MA MSA plans (IRC §138)

If you have multiple account types, you receive separate 5498-SAs for each.

Reconciling Form 5498-SA Against Form 8889

The point of receiving 5498-SA is to verify what you reported on Form 8889. Here is the reconciliation, line by line.

Form 8889 Line 2 (Direct contributions) ↔ Form 5498-SA Box 2 minus employer/cafeteria contributions

Box 2 includes everything that hit the HSA during the calendar year. Form 8889 Line 2 includes only direct contributions you made personally — not employer contributions and not cafeteria plan contributions (those go on Line 9).

To reconcile, start with Form 5498-SA Box 2, subtract W-2 Box 12 code W (cafeteria-plan and employer-only contributions), then subtract any Box 4 rollover amounts that were mistakenly posted to Box 2. The result is your direct contributions, which should match Form 8889 Line 2.

If they don't match, possible explanations:

• A January contribution you made was credited by the custodian as a prior-year contribution (so it's on the prior year's Box 3 instead of the current year's Box 2)
• A contribution check you mailed in late December didn't clear until January (so it's on the next year's Box 2)
• The custodian made a clerical error
• You misremembered how much you contributed

Form 8889 Line 9 (Employer contributions) ↔ W-2 Box 12 code W (NOT Form 5498-SA Box 2 alone)

This is the trap. Form 8889 Line 9 reports employer HSA contributions, which appear on W-2 Box 12 code W, not on Form 5498-SA. The 5498-SA lumps employer + employee + cafeteria contributions all into Box 2. To separate them, you need both forms:

• Box 12 code W on the W-2 = employer + cafeteria-plan portion (both treated as employer contributions for tax purposes)
• 5498-SA Box 2 minus W-2 Box 12 code W = direct contributions

If the W-2 Box 12 code W amount is wrong, contact your employer's payroll department immediately. The W-2 is the authoritative source for the employer-contribution figure that lands on Form 8889 Line 9.

Form 8889 Line 14a (Distributions): does NOT come from Form 5498-SA

Distributions are reported on Form 1099-SA, which is a separate form sent in late January. Form 5498-SA only covers contributions and balance. Don't confuse the two — many filers do.

Form 8889 Line 13 (HSA deduction): derived, not reconciled

Line 13 is computed from Lines 2, 3, 8, 9, 10, 11, 12. It is the deduction amount that flows to Schedule 1 Line 13. Form 5498-SA does not show the deduction directly — that is calculated on your tax return.

---

The Prior-Year Contribution Trap

The single most common reconciliation problem: a contribution made between January 1 and April 15 that you designate as a prior-year contribution.

Example timeline:

• February 14, 2026: You write a check for $1,500 to Fidelity HSA, with a note saying "for tax year 2025"
• April 10, 2026: You file Form 8889 for 2025 with $5,800 on Line 2 (including the $1,500)
• May 28, 2026: You receive two Forms 5498-SA from Fidelity:
  • 2025 Form 5498-SA showing Box 2 = $4,300 (only your 2025 calendar-year contributions)
  • 2026 Form 5498-SA showing Box 3 = $1,500 (the prior-year-designated contribution made in early 2026)

If you only look at the 2025 form, you'll see $4,300 and panic — you reported $5,800 on Line 2 and the IRS shows only $4,300. Excess contribution! Audit!

But the $1,500 is right there on the 2026 form's Box 3, properly designated. The IRS knows. No problem. You just need to look at both Forms 5498-SA together to see the full picture for tax year 2025.

The lesson: always pull last year's 5498-SA AND this year's 5498-SA when reconciling Form 8889.

Worked Example: Marcus, 38, Family HDHP

To make this concrete, here is how a married father reconciles a Form 5498-SA against a Form 8889 he already filed.

Background:

• Marcus, age 38, employed full-time
• Married, two kids, family HDHP through his employer
• HSA at Fidelity since 2018; cumulative balance approximately $43,200 at year-end 2025
• For tax year 2025, Marcus contributed the full family limit of $8,550 — split between cafeteria plan ($6,000) and direct deposits from his bank ($2,550)
• Marcus filed Form 8889 on April 12, 2026, before the deadline
• On May 18, 2026, he receives Form 5498-SA from Fidelity

What Marcus's Form 5498-SA Shows

Fidelity sends Marcus a Form 5498-SA (account ending 7842) reporting:

What Marcus's Form 8889 (Already Filed) Showed

Line 12 subtracts the $6,000 of employer/cafeteria money (Line 11) from the $8,550 total limit (Line 8), leaving $2,550 of room for a personal deduction. That matches Marcus's $2,550 of direct contributions on Line 2, so his deduction on Line 13 is $2,550. Writing Line 12 as "Line 2 + Line 11" is the common error that would wrongly show $8,550 here.

Reconciliation

Marcus reconciles cleanly. He files the 5498-SA in his tax records folder and moves on.

What If the Numbers Didn't Match?

Suppose Box 2 had read $9,050 instead of $8,550 — $500 more than Marcus reported. The reconciliation paths:

1. Custodian error: Marcus calls Fidelity, asks them to check the deposit history. If they over-counted (e.g., posted a transfer twice), Fidelity issues a corrected Form 5498-SA marked "CORRECTED" and refiles with the IRS.
2. Marcus's error: Marcus actually did contribute $9,050 — exceeding the $8,550 family limit by $500. He has an excess contribution. He must withdraw the $500 plus earnings before the extended October 15, 2026 filing deadline (he can file an extension to buy time) or pay a 6% excise tax on Form 5329 every year the excess remains.
3. Designation error: Marcus made an extra $500 deposit in December 2025 that he intended as a 2026 contribution but didn't designate properly. He calls Fidelity and asks them to recharacterize the December deposit as a 2026 contribution (this is generally allowed if done before the tax filing deadline).
4. Amend Form 8889: If Marcus had under-reported, he files Form 1040-X with a corrected Form 8889 to claim the additional deduction.

Key takeaway: the reconciliation is usually clean if you track contributions month-to-month. When it's not clean, the cause is almost always a mid-January contribution that was designated for the prior year — easy to fix once you spot it.

Common Mistakes to Avoid

Mistake #1: Throwing Away the 5498-SA Without Reading It

Problem: The 5498-SA arrives after April 15, looks like junk mail from your HSA custodian, and goes straight in the recycling.

Impact: You miss the chance to catch reconciliation errors. If the custodian reported a different number to the IRS than you reported on Form 8889, the CP2000 notice arrives 12 to 18 months later asking for tax, interest, and penalties on the discrepancy.

Solution: When 5498-SA arrives in May, spend 10 minutes reconciling it against your filed Form 8889 and W-2 Box 12 code W. File it with that year's tax records.

Mistake #2: Treating Form 5498-SA Box 2 as the Form 8889 Line 2 Number

Problem: Filers see Box 2 = $8,550, copy that number to Form 8889 Line 2, and claim an $8,550 deduction. But Box 2 includes employer and cafeteria plan contributions that already came out pre-tax on the W-2.

Impact: Double-counting the deduction. The IRS catches this through Form W-2 cross-check and issues a CP2000.

Solution: Form 8889 Line 2 = direct contributions only. Subtract W-2 Box 12 code W from 5498-SA Box 2 to get the direct portion.

Mistake #3: Confusing Form 5498-SA with Form 1099-SA

Problem: Filers receive both forms (1099-SA in January, 5498-SA in May) and conflate them. They report 1099-SA distributions on Form 8889 but ignore 5498-SA, or vice versa.

Impact: Either contributions or distributions go unreported, triggering an IRS notice.

Solution: Keep them straight: 1099-SA = distributions out (reported on Form 8889 Line 14a). 5498-SA = contributions in (reconciled against Form 8889 Lines 2 and 9). Different forms, different roles.

Mistake #4: Missing the Prior-Year Contribution Across Two 5498-SAs

Problem: A January 2026 contribution designated as a 2025 prior-year contribution lands on the 2026 Form 5498-SA Box 3, not the 2025 form. Filers reconcile only against the 2025 form and panic about a "missing" contribution.

Impact: Filers waste hours arguing with the custodian about a contribution that is properly recorded — just on a different year's form.

Solution: When reconciling Form 8889, pull both the current year 5498-SA (for current-year contributions, Box 2) and the next year's 5498-SA (for prior-year designated contributions, Box 3). Both pieces are needed for a full picture.

Mistake #5: Ignoring Box 5 (Fair Market Value)

Problem: Box 5 shows the year-end account balance. Many filers ignore it because it doesn't flow to any Form 8889 line.

Impact: Two issues. First, the IRS uses Box 5 trends to flag potential excess contributions and untracked rollovers. If your account jumps by more than the contribution + reasonable growth, expect a query. Second, you lose track of the asset for net-worth, estate, and tax-planning purposes.

Solution: Record Box 5 each year. The HSA can grow into a meaningful retirement asset over decades — track it like any other investment account.

Action Checklist: Form 5498-SA

Throughout the Year

• Track every HSA contribution as it happens (date, amount, source)
• Note whether each contribution is employer / cafeteria plan / direct / rollover
• Save year-end statement (December 31 balance) when custodian issues it in January
• Track HSA-to-HSA rollovers (limit: one per 12-month period)

Before April Filing Deadline

• File Form 8889 using year-end statement and W-2 Box 12 code W
• Confirm direct contributions on Line 2 match your bank records
• Confirm Line 9 matches W-2 Box 12 code W exactly
• If making prior-year contributions in early next year, designate them properly with the custodian

When 5498-SA Arrives (Late May)

• Verify header information (name, SSN, address) is correct
• Compare Box 2 to (Form 8889 Line 2 + Line 9): should match
• Verify Box 5 (year-end FMV) matches your December custodian statement
• Check Box 6 confirms HSA (not Archer MSA or Medicare Advantage MSA, unless that is what you have)
• If reconciliation fails, contact custodian within 30 days
• If reconciliation requires amending Form 8889, file Form 1040-X
• File 5498-SA with that year's tax records (keep at least 3 years; ideally indefinitely while HSA is open)

When You Have Two 5498-SAs to Reconcile

• Pull current-year 5498-SA (for current-year contributions, Box 2)
• Pull next-year 5498-SA (for prior-year designated contributions, Box 3)
• Sum (current Box 2) + (next year Box 3) to get total contributions for the tax year
• Compare to Form 8889 Line 2 + Line 9

Final Thoughts

Form 5498-SA is not paperwork you file. It is paperwork you reconcile against. The reconciliation takes 10 minutes once a year and saves you a CP2000 notice 18 months later if anything is off.

The strategies that actually move the needle:

1. Open the envelope when 5498-SA arrives in May: don't let it pile up with junk mail
2. Reconcile Box 2 against (Form 8889 Line 2 + Line 9): they should equal exactly
3. Pull two consecutive years' 5498-SAs when you made a prior-year contribution between January and April
4. Track Box 5 year over year: your HSA balance is a real retirement asset, and the IRS uses Box 5 trends to spot anomalies
5. Contact the custodian within 30 days of receiving the form if anything looks wrong — corrections are routine if requested promptly

The HSA's triple tax advantage compounds for decades. Form 5498-SA is the audit trail that proves it.
