Your HSA tax forms come from three places. The financial institution that holds your Health Savings Account sends you Form 1099-SA (if you took money out) and Form 5498-SA (contributions and year-end value). Your employer reports any payroll HSA contributions on your W-2 in Box 12 with Code W. And you prepare one form yourself: IRS Form 8889, which you attach to your Form 1040. So if you’re wondering where to get your HSA tax form, the short answer is that most of it is issued to you, and one piece you fill out.
The Two Forms Your HSA Custodian Sends
Your custodian is the bank, credit union, or brokerage that holds the account. It’s required to send two information returns to both you and the IRS each year.
Form 1099-SA (Distributions)
Form 1099-SA reports every dollar that left your HSA during the calendar year. Box 1 shows the total gross distribution — all withdrawals, whether or not they went toward medical bills. Box 3 carries a distribution code identifying the type of withdrawal: normal, excess contribution removal, disability, death, and so on.1Internal Revenue Service. Form 1099-SA – Distributions From an HSA, Archer MSA, or Medicare Advantage MSA
If you took no distributions during the year, you won’t receive this form. The IRS requires custodians to furnish it by January 31.2Internal Revenue Service. Instructions for Forms 1099-SA and 5498-SA
Form 5498-SA (Contributions and Year-End Value)
Form 5498-SA documents all contributions to your account for the tax year, including both yours and your employer’s, and shows the fair market value of the account as of December 31 in Box 5.3Internal Revenue Service. Form 5498-SA – HSA, Archer MSA, or Medicare Advantage MSA Information
This one arrives later than most tax documents. Because you can make prior-year HSA contributions up to the April filing deadline, the custodian can’t finalize the form until after that window closes. Many don’t post it until late May. That’s fine. You already know what you contributed, and 5498-SA is mostly a confirmation for your records. Don’t wait for it to file.
Payroll Contributions Show Up on Your W-2
If your employer contributes to your HSA, or if you contribute through pre-tax payroll deductions, the total appears on your W-2 in Box 12 with Code W.4Internal Revenue Service. Form W-2 Reporting of Employer-Sponsored Health Coverage That single figure combines employer money and any of your own contributions run through payroll.
Those dollars were already excluded from your taxable wages, so you don’t deduct them again. But you still need to report the Code W amount on Form 8889, because it counts against your annual contribution limit.
Contributions you made on your own, outside payroll, won’t appear on the W-2. Those show up only on Form 5498-SA, and those are the amounts you claim as a deduction.
How to Actually Get the Forms
Most custodians post tax documents to a secure online portal, usually under a section labeled “Tax Documents” or “Tax Center” in your account dashboard. If you opted into paperless delivery, that portal may be the only place they appear. Otherwise, expect a mailed copy too.
If you haven’t seen your 1099-SA by mid-February, contact the custodian directly. Form 5498-SA can legitimately take until late May.
Your W-2 comes from your employer’s payroll system, not the HSA custodian, and follows the same January 31 deadline as other wage forms.
Form 8889 Is the One You Prepare Yourself
The information from your 1099-SA, 5498-SA, and W-2 all feeds into IRS Form 8889, “Health Savings Accounts (HSAs).” This is the form that calculates your deduction, determines whether your distributions are taxable, and checks that you stayed within the contribution limits. You must file Form 8889 with your Form 1040 for any year you had HSA contributions, took distributions, or otherwise need to report activity.5Internal Revenue Service. Instructions for Form 8889
The form has two main parts you’ll almost certainly touch:
Part I works out your deduction. You enter total contributions from all sources and apply the annual limit for your coverage type. For 2026, the limits are $4,400 for self-only coverage and $8,750 for family coverage, with an extra $1,000 catch-up allowed if you’re 55 or older. To be eligible in the first place, you need an HDHP: for 2026, a minimum deductible of $1,700 (self-only) or $3,400 (family), with out-of-pocket costs capped at $8,500 or $17,000 respectively.6Internal Revenue Service. Revenue Procedure 2025-19 Pre-tax payroll contributions (Box 12, Code W) don’t generate a fresh deduction here because they already reduced your taxable wages. Only your after-tax, direct contributions produce a new above-the-line deduction, which lowers your AGI whether or not you itemize.
Part II tests your distributions. Start with the total from Form 1099-SA, subtract what you spent on qualified medical expenses that weren’t reimbursed by insurance, and if the numbers line up you owe nothing extra. If distributions exceed qualified expenses, the difference is added to your ordinary income. If you’re under 65, an additional 20% tax applies to the non-qualified amount. That penalty doesn’t apply if you’re 65 or older, disabled, or the distribution was made after the account holder’s death.7Office of the Law Revision Counsel. 26 U.S.C. 223 – Health Savings Accounts
There’s also a Part III that handles the “last-month rule” and its testing period, which only matters if you became HSA-eligible partway through the year and want to contribute the full annual amount.5Internal Revenue Service. Instructions for Form 8889
The Records No One Sends You
Your custodian doesn’t verify that your withdrawals paid for qualified medical expenses. Nobody checks at the time of the withdrawal. If the IRS ever asks, the burden is on you to show that each distribution paid for a qualifying expense, that insurance didn’t reimburse it, and that you didn’t also claim it as an itemized medical deduction.8Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans
Qualified expenses are broadly defined as costs for diagnosing, treating, or preventing disease: doctor visits, prescriptions, dental, vision, medical equipment. General-health items like a gym membership or daily vitamins don’t count. Things like nutritional counseling or weight-loss programs qualify only when they treat a specific disease diagnosed by a physician.9Internal Revenue Service. Frequently Asked Questions About Medical Expenses Related to Nutrition, Wellness, and General Health
Don’t send receipts with your return. Keep them with your tax records. There’s no time limit on reimbursing yourself from your HSA for a qualified expense, so many people let the account grow and reimburse older expenses later. That only works if you still have the paperwork.
A Couple of Situations That Change What You Receive
If you moved your HSA to a new custodian, how the move happened matters. A trustee-to-trustee transfer, where funds go directly between institutions, is not treated as a distribution and won’t appear on Form 1099-SA. A rollover, where the money is paid to you and you redeposit it in a new HSA within 60 days, is reported, and if you miss the 60-day window the whole amount becomes a taxable distribution with the 20% penalty attached if you’re under 65. Rollovers are also limited to one per 12-month period; transfers aren’t.
State treatment can also affect your W-2. Most states follow the federal HSA rules, but a handful do not. In those states, your payroll HSA contributions aren’t excluded from state taxable wages, so your state wage figure on the W-2 will be higher than the federal one. Check your state’s instructions if you’re not sure how yours handles HSAs.
If you contributed more than the annual limit, the fix is to withdraw the excess plus its earnings before your filing deadline (including extensions); only the earnings are taxable in that case. If the excess stays in the account past the deadline, a 6% excise tax applies each year until it’s cleared, and you report that on Form 5329.10Office of the Law Revision Counsel. 26 U.S.C. 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities11Internal Revenue Service.
