Summary: For 2026 the IRS allows HSA contributions of $4,400 with self-only HDHP coverage and $8,750 with family coverage, plus a $1,000 catch-up per person 55 or older (Revenue Procedure 2025-19). Employer and employee contributions share one cap; limits are prorated by eligible months with a last-month-rule exception; 2026 contributions can be made until April 15, 2027. The triple tax advantage (deductible in, tax-free growth, tax-free medical withdrawals, plus 7.65% FICA savings via payroll) makes the HSA the most tax-efficient account in the code.
How HSA contributions work in 2026
A Health Savings Account is available only if you are enrolled in a qualifying high-deductible health plan and meet the other eligibility tests: no disqualifying coverage (like a general-purpose FSA), no Medicare enrollment, and not claimed as a dependent. For 2026 the IRS set the contribution limits at $4,400 for self-only coverage and $8,750 for family coverage, with a $1,000 catch-up for each account holder 55 or older (Revenue Procedure 2025-19).
The limit is shared: everything counts toward the same cap, your payroll deductions, your employer's contributions, and any direct deposits. If your employer puts in $1,000 and you have family coverage, you can add $7,750 yourself (plus catch-ups). Contribute even one dollar over the limit and the excess faces a 6 percent excise tax every year until withdrawn, so tracking the running total matters.
The payoff is the triple tax advantage: contributions are deductible (and via payroll they also skip the 7.65 percent FICA tax), growth is tax-free, and withdrawals for qualified medical expenses are tax-free at any age. After 65, non-medical withdrawals are taxed like a Traditional IRA with no penalty, which is why many planners treat the HSA as a retirement account in disguise.
Worked example
Family coverage, both spouses under 55, employer put in $1,000, employee contributed $2,500: total $3,500 against the $8,750 limit leaves $5,250 of room. Contributing the remaining $5,250 via payroll at a 22 percent federal plus 5 percent state rate saves $1,418 in income tax plus $402 in FICA, $1,820 total, and the money grows tax-free until used for medical expenses.
