Quick answer: The 2026 HSA limits are $4,400 for self-only coverage and $8,750 for family coverage before eligible catch-up contributions. Eligibility, contribution deductions and tax-free distributions are separate tests. Reconcile all funding sources and keep evidence for reimbursements.
Confirm contribution eligibility
For a month, you generally must have HSA-compatible coverage on its first day, have no disqualifying other coverage, not be enrolled in Medicare, and not be claimable as another taxpayer’s dependent. A general-purpose health FSA or HRA can disqualify you, including some coverage through a spouse. Merely having a high deductible does not establish eligibility. See IRS Publication 969.
Medicare enrollment can be retroactive. Confirm its effective date before calculating contributions; contributions allocated to Medicare-covered months can be excess even if you applied later. Losing contribution eligibility does not itself prevent tax-free withdrawals for qualified expenses from an existing HSA.
Changes effective in 2026
Certain bronze and catastrophic plans are HSA-compatible from January 1, 2026, including qualifying plans purchased outside an Exchange. Certain direct primary care arrangements also no longer prevent contributions, and qualifying periodic fees can be paid from an HSA. For 2026, the applicable monthly aggregate DPC fee ceiling is $150 for one person or $300 for more than one person; the arrangement must meet the service requirements. These exceptions do not remove the other eligibility tests. IRS Notice 2026-05 explains the conditions, including the permanent telehealth relief for plan years beginning after 2024.

Calculate the amount you can contribute
| 2026 item | Amount |
|---|---|
| Self-only annual contribution limit | $4,400 |
| Family annual contribution limit | $8,750 |
| Additional contribution for an eligible individual age 55 or older by year-end | $1,000, subject to eligibility |
The base limits come from Revenue Procedure 2025-19. Aggregate employer, pretax payroll, personal and other contributions across your HSAs; opening another account does not create another limit. Married eligible spouses generally share the family limit, and each eligible spouse’s catch-up contribution must go into that spouse’s own HSA.
Part-year eligibility or coverage changes generally require a monthly calculation. The last-month rule can allow a larger contribution when eligible on December 1, but its testing period runs through December 31 of the following year. Failure to remain eligible, other than for death or disability, can trigger income inclusion and a 10% additional tax on the amount attributable to that rule. Use the Form 8889 instructions for the calculation.
For example, with full-year self-only eligibility in 2026 and no catch-up allowance, $1,400 from an employer plus $2,000 through pretax payroll leaves $1,000 of the $4,400 limit for other contributions. That arithmetic assumes no contributions to another HSA.
Contributions for 2026 generally can be made through the 2026 return’s due date in 2027, without extensions, and must be designated for 2026. Do not deduct employer or pretax payroll contributions again on your individual return.
Document tax-free reimbursements
Qualified expenses must be incurred after the HSA was established and cannot be reimbursed by insurance or another source or also claimed as an itemized medical deduction. A later reimbursement of an older eligible expense is possible when those conditions and adequate records are maintained. There is no requirement to empty an HSA annually. Publication 969 explains qualified expenses and distributions.
Nonqualified withdrawals are generally taxable and can carry a 20% additional tax. The additional tax does not apply after age 65, disability or death, although ordinary income treatment may still apply. HSA trustee approval of a withdrawal does not establish its tax treatment.
Keep one reconciled HSA file
- Coverage and Medicare effective dates, plus information about any other health coverage.
- Employer and payroll records, including Form W-2 box 12 code W, and personal contribution confirmations.
- Forms 5498-SA and 1099-SA, account statements and the contribution year assigned to each deposit.
- Medical receipts, insurance explanations and proof of payment.
- A reimbursement log showing expense date, eligible person, amount, HSA withdrawal date and whether any amount was paid or deducted elsewhere.
Use these records to complete Form 8889 with the individual return. A distribution-year form and an expense-year receipt can relate to the same later reimbursement; record the connection so the expense is not used twice.
Correct excess contributions promptly
An excess is not deductible and generally incurs a 6% excise tax for each year it remains. A timely correction generally requires withdrawal of the excess and attributable earnings by the return due date, including extensions. Earnings have their own income-reporting treatment. Ask the custodian to process an excess-contribution return and review Form 5329 rather than simply making an ordinary distribution. See Publication 969, Excess contributions.

Common questions
What HSA contributions are deductible?
Eligible personal contributions, including amounts another person contributes on your behalf, may be deductible within your applicable limit. Employer contributions and pretax payroll contributions excluded from wages are not deducted again.
What makes an HSA distribution qualified?
It must cover an eligible medical expense incurred after the HSA was established, for an eligible person, without reimbursement from another source or an itemized deduction for that expense. Retain records supporting each condition.
What documentation should be kept for HSA expenses?
Keep dated receipts, payment and insurance records, HSA statements, and a log connecting each reimbursement to an expense. Retain contribution records, coverage dates and tax forms as well.
Can I correct an excess contribution after December 31?
Potentially. The timely correction process generally requires the custodian to return the excess and attributable earnings by the return due date including extensions. Review reporting and earnings treatment; an ordinary withdrawal is not automatically an excess-contribution correction.
