HSA contribution limits for 2025 and 2026, and the eligibility rules that just changed too

For 2026, the IRS raised the HSA contribution limit to $4,400 for self-only coverage and $8,750 for family coverage, each up modestly from $4,300 and $8,550 in 2025. The bigger story this year is not the dollar increase, which is routine. It is that the One Big Beautiful Bill Act (OBBBA) rewrote part of who is even allowed to have an HSA in the first place, opening the account to people who were shut out of it before — regardless of how the base limit moved.

2025 versus 2026, side by side

Every figure in that table comes from the IRS's own inflation-adjustment guidance — Revenue Procedure 2024-25 for 2025 and Revenue Procedure 2025-19 for 2026. The contribution limits and the HDHP thresholds are adjusted separately under the same statute, which is why they do not move by identical dollar amounts in the same year.

The one HSA number that never moves

The age-55 catch-up contribution is the exception in that table, and it is worth noticing why. Congress fixed it at $1,000 when the current catch-up rules took effect in 2009 and never wrote an inflation adjustment into the statute for that specific figure — unlike the base contribution limits, which are indexed every year under Internal Revenue Code Section 223. A 401(k) or IRA catch-up, by comparison, does get adjusted periodically. Seventeen years on, $1,000 buys noticeably less than it did in 2009, while the base limit around it has more than doubled. Someone 55 or older with self-only coverage can contribute $5,400 in 2026 in total ($4,400 plus the catch-up); with family coverage the ceiling is $9,750. If both spouses on a family plan are 55 or older, each gets their own $1,000 catch-up, but — this is a common paperwork mistake — a spouse's catch-up has to go into that spouse's own HSA, not into a single shared family account.

Who can open an HSA changed more than how much they can put in

The bigger 2026 development is eligibility, not the dollar limit. Treasury and the IRS issued Notice 2026-5 explaining three changes the OBBBA made to who qualifies for an HSA in the first place:

• Bronze and Catastrophic ACA marketplace plans now count, effective January 1, 2026, even when they do not meet the usual HDHP deductible and out-of-pocket rules shown in the table above. Before this change, someone buying a Bronze or Catastrophic plan on an Exchange was frequently locked out of HSA eligibility entirely, regardless of income or health status.
• Telehealth and other remote care can be offered before the deductible is met without breaking HSA eligibility — a pandemic-era safe harbor that repeatedly expired and had to be temporarily renewed by Congress, now made permanent, effective for plan years beginning after December 31, 2024.
• Direct primary care (DPC) arrangements no longer disqualify someone from HSA eligibility, effective January 1, 2026, and DPC fees can themselves be paid tax-free from the HSA as a qualified medical expense. Previously, a membership-style DPC arrangement was often treated as a form of health coverage that conflicted with HDHP-only coverage, which blocked HSA contributions altogether.

None of these three changes affects the $4,400/$8,750 contribution ceiling itself. What they change is the population of people who are allowed to contribute anything to an HSA at all — specifically, marketplace shoppers on low-premium plans and people using membership-based primary care, two groups that the pre-2026 rules mostly excluded.

Why the account is worth the eligibility fight

An HSA is the only account in the US tax code that shelters money at every single stage. A contribution reduces 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. A withdrawal is tax-free too, with no deadline, as long as it pays for a qualified medical expense, even one incurred years earlier as long as it happened after the HSA was opened. A 401(k) or traditional IRA only gets you the first two of those three breaks; a Roth IRA only the last two. Unused money also carries over indefinitely — there is no "use it or lose it" rule of the kind that governs most Flexible Spending Accounts, and the account is fully portable between jobs and HDHP plans.

What the catch-up is worth on a real income

Take a 57-year-old with self-only HDHP coverage who is in the 24% federal marginal bracket and maxes out both the base limit and the catch-up for 2026 through payroll deduction:

That $1,296 is only the income-tax side of the saving. A contribution made through payroll deduction under a Section 125 cafeteria plan also typically avoids the 7.65% combined Social Security and Medicare payroll tax, which a contribution written by personal check after payday does not — a distinction worth checking with your own payroll department, since not every employer routes HSA contributions the same way. Either way, none of this tax treatment depends on the money ever being spent on healthcare in the same year it was contributed; it can sit invested for decades and still come out tax-free against a qualified expense.

The deadline is not December 31

Unlike a workplace FSA, which typically has to be funded through payroll by the end of the plan year, an HSA contribution for a given tax year can be made any time up to that year's federal tax filing deadline — mid-April of the following year, not extended by a filing extension. A direct contribution outside of payroll also still needs to be reported and, where applicable, deducted on Form 8889 when the return is filed. Enrolling in Medicare at any point during the year, even mid-year, ends HSA eligibility going forward for that person, though it does not affect money already contributed or invested in the account.
