How much you can put into an HSA in 2026

For 2026, the IRS raised the HSA contribution limit to $4,400 for self-only coverage and $8,750 for family coverage, both up modestly from 2025. The 55-and-older catch-up holds at $1,000, exactly where it has sat since 2009 — the one HSA figure that never moves with inflation, by design. Together these numbers set the ceiling on what is still the only account in the tax code that shelters money three separate times: going in, growing, and coming back out for a qualified medical expense.

Every HSA and HDHP figure that changed for 2026

These are the figures published in the IRS's Revenue Procedure 2025-19, which sets every HSA and HDHP dollar amount for calendar year 2026 in one document. As with most IRS inflation adjustments, each figure is rounded independently, which is why the increases above are not identical percentages of one another.

Why the catch-up amount never moves

The base HSA limits are indexed to inflation every year under Internal Revenue Code Section 223, which is why self-only and family coverage both went up again for 2026. The age-55 catch-up is different: Congress set it at $1,000 when the current HSA catch-up rules took effect in 2009, and the statute never built in an inflation adjustment for that particular number. It has stayed flat for 17 straight years while the base limits climbed around it. That is the opposite of how 401(k) and IRA catch-ups work — those are indexed and have grown noticeably over the same period — so an HSA catch-up that felt generous in 2009 is worth considerably less in practical terms today.

What counts as a high-deductible health plan in 2026

Contributing to an HSA at all requires enrollment in a qualifying high-deductible health plan (HDHP), and that qualification is defined by the same revenue procedure. For 2026 a plan has to carry an annual deductible of at least $1,700 for self-only coverage or $3,400 for family coverage, and its total annual out-of-pocket costs — deductibles, copayments and coinsurance, but not premiums — cannot exceed $8,500 self-only or $17,000 family. A plan with a lower deductible than the minimum does not qualify, no matter how it is marketed, and a plan whose out-of-pocket maximum runs higher than the ceiling does not qualify either. Coverage by most other health plans, including a general-purpose Flexible Spending Account or enrollment in Medicare, makes someone ineligible to contribute to an HSA even while the HDHP itself remains in force.

The only account with three separate tax breaks

An HSA is the single account type in the US tax code that shelters money at every stage. Contributions reduce taxable income going in, whether made directly or through payroll deduction. Growth inside the account — interest, dividends, capital gains — is never taxed while it stays in the HSA. Withdrawals are entirely tax-free too, as long as the money pays for a qualified medical expense, with no time limit on when that withdrawal happens relative to the expense being incurred. A 401(k) or traditional IRA only manages the first two of those three; a Roth IRA only the last two. Unused HSA balances also carry over indefinitely — there is no "use it or lose it" rule of the kind that applies to most FSAs.

How the self-only limit has moved since 2022

The $300 jump for 2024 was the largest single-year increase in the limit's history, a direct result of the inflation spike measured over 2022 and 2023. The smaller $100 step for 2026 reflects inflation cooling back toward more typical levels, not any change in how the adjustment itself is calculated — the same statutory inflation-indexing formula under Section 223 has applied every year shown here.

What maxing out a family HSA is worth in 2026

Take a family enrolled in a qualifying HDHP where the employer contributes $1,000 a year directly to the HSA, and the employee contributes the rest of the $8,750 family limit through payroll deduction:

That saving is on top of whatever the $8,750 eventually pays for, and it exists because a payroll-deducted HSA contribution — unlike a 401(k) deferral — typically avoids Social Security and Medicare payroll tax as well as income tax, not income tax alone. Left invested rather than spent, the future value calculator shows what a contribution like this is worth after a chosen number of years at an assumed return, and the benefits value calculator puts a total dollar figure on an HSA alongside the rest of an employment benefits package.

What to check against your own coverage

• The $8,750 family limit is a combined ceiling across employer and employee contributions together, not $8,750 on top of whatever an employer puts in.
• Confirm your specific plan actually meets the 2026 minimum deductible and maximum out-of-pocket figures above — a plan that qualified in 2025 does not automatically still qualify if its terms did not move along with the IRS numbers.
• Enrolling in Medicare at any point during the year, even mid-year, ends HSA eligibility for the months after enrollment, which typically requires prorating the annual limit.
