The HSA tax deduction lets you subtract the money you put into a health savings account from your income, up to $4,400 for self-only coverage or $8,750 for family coverage in 2026, plus an extra $1,000 if you are 55 or older. You claim it on Form 8889 and Schedule 1 whether or not you itemize, and contributions your employer makes through payroll are excluded from your wages instead.
To contribute at all, you must be covered by a high-deductible health plan (HDHP) and have no other disqualifying coverage. The One Big Beautiful Bill Act widened that door from 2026: marketplace bronze and catastrophic plans now count as HDHPs, and certain direct primary care memberships no longer disqualify you.
HSA contribution limits by year
- 2025: $4,300 self-only, $8,550 family.
- 2026: $4,400 self-only, $8,750 family (Rev. Proc. 2025-19).
- 2027: $4,500 self-only, $9,000 family (Rev. Proc. 2026-24), useful if you are planning next year's payroll elections now.
- Age 55 catch-up: $1,000 in each year, not indexed for inflation.
The limit covers everything going into your account: your own deposits, your employer's contributions and anything a family member adds. If you are married and both of you are 55 or older, each spouse can add the $1,000 catch-up, but only into an HSA in his or her own name. There are no joint HSAs.
What counts as an HDHP in 2026
For 2026, a plan qualifies if its deductible is at least $1,700 (self-only) or $3,400 (family) and its out-of-pocket maximum, excluding premiums, is no more than $8,500 or $17,000. Notice 2026-5 explains three changes made by the 2025 law:
- Bronze and catastrophic marketplace plans. For months beginning after December 31, 2025, bronze and catastrophic plans available as individual coverage through an Exchange are treated as HDHPs (Notice 2026-5 says this includes the same plans bought off-Exchange), even though many have out-of-pocket maximums above the usual cap.
- Telehealth. An HDHP can cover telehealth and remote care before the deductible without costing you eligibility. The relief is permanent and applies retroactively to plan years beginning after December 31, 2024.
- Direct primary care. For months beginning after December 31, 2025, a direct primary care arrangement with a fixed fee of no more than $150 a month ($300 if it covers more than one person) does not disqualify you, and you can pay the fee from your HSA.
You also must not be enrolled in Medicare. Your contribution limit drops to zero starting with the first month of Medicare coverage, including retroactive coverage, so plan the timing if you are approaching 65 and still working.
How the deduction works, by how you contribute
Through an employer's cafeteria plan
If you elect HSA contributions through payroll, they come out of your pay before income tax and are excluded from your Form W-2 wages. The IRS says these employer contributions generally aren't subject to employment taxes either. You don't deduct them again on your return; they still count toward your annual limit.
On your own
If you deposit money directly with your HSA custodian, you report it on Form 8889 and deduct it on Schedule 1 (line 13 on the 2025 form). The deduction reduces your adjusted gross income. This is the route for sole proprietors, freelancers and anyone whose employer doesn't offer payroll HSA deposits.
Partners and S corporation owners
A partnership's HSA contribution for a partner is treated either as a distribution or as a guaranteed payment, and an S corporation's contribution for a 2% shareholder-employee is treated as a guaranteed payment. In the guaranteed-payment cases the amount is included in the owner's income; in every case the owner can generally deduct the contribution on their own return. Which treatment applies depends on how the business pays it, so set it up with your CPA.
Deadlines and eligibility rules that trip people up
- Contribution deadline. You can contribute for a year up to your return's due date, without extensions. For 2025 that was April 15, 2026; 2026 contributions can be made until the April 2027 deadline.
- Partial-year coverage. If you are eligible only part of the year, the limit is generally prorated by month. The exception is the last-month rule: if you are eligible on December 1, you can contribute the full-year amount, but you must stay eligible through the following December (the testing period). Fail that, and the extra contribution becomes taxable plus a 10% additional tax.
- Spending. Withdrawals for qualified medical expenses are tax-free. Other withdrawals are taxable and, before age 65 or disability, carry a 20% additional tax.
Worked example: an Omaha electrician on a bronze plan, tax year 2026
Tomás, 56, is a self-employed electrician filing a Schedule C. His wife Elena, 52, works part-time with no employer insurance. For 2026 they switch to a family bronze plan from the marketplace, which now qualifies as an HDHP from January.
- Limit. Family coverage for the full year: $8,750. Tomás is over 55, so he adds $1,000, for $9,750. Elena is under 55, so there is no second catch-up.
- Contribution. Tomás moves $812.50 a month from his business checking account to his HSA, totaling $9,750 by December.
- Deduction. He reports the $9,750 on Form 8889 and claims it on Schedule 1, cutting their AGI by that amount.
- Tax effect. If their top federal bracket is 22%, the deduction saves roughly $2,145 of federal income tax. It does not reduce his self-employment tax, because SE tax is figured on Schedule C profit, before Schedule 1 adjustments.
- Premiums. His bronze premiums are a separate matter: as a sole proprietor with no access to an employer plan, he may be able to deduct them as self-employed health insurance on Form 7206. He shouldn't pay them from the HSA, which generally can't be used for insurance premiums.
He also records the transfers as owner's draws in his books, not as a business expense, so his Schedule C profit stays accurate.
Common mistakes
- Double-dipping on payroll contributions. Amounts shown in W-2 box 12 with code W are already excluded; deducting them again overstates the deduction.
- Exceeding the family limit as a couple. The family figure is shared between spouses, apart from each person's own catch-up.
- Contributing after Medicare starts. Retroactive Medicare coverage can make months you thought were eligible ineligible.
- Booking HSA deposits as a business expense on Schedule C. That lowers self-employment tax improperly; your own HSA belongs on Schedule 1.
- Losing receipts. Tax-free withdrawals depend on qualified expenses you can document if asked.

If you fund an HSA from a business account, HelloBooks makes it easy to keep those transfers out of your expenses. A bank rule can tag every HSA transfer to an owner's draw account the moment it arrives through your bank feed, so your P&L reflects real business costs. Medical receipts you photograph in the mobile app are read by document extraction and stored with the transaction, which gives you a dated trail if you reimburse yourself from the HSA years later. At year-end, a general ledger report of the draw account shows your total contributions for Form 8889. You or your preparer still decides what goes on the return.
This is general information as of November 2026, not tax advice. HSA eligibility depends on your specific coverage, so check Publication 969 and Notice 2026-5 on irs.gov or ask a CPA or enrolled agent before you contribute.
