The IRS raised HSA contribution limits again for 2026. Here are the new figures, the HDHP rules behind them, and the deadlines that actually matter.
Electing coverage for 2027? The IRS has published the 2027 figures — $4,500 self-only and $9,000 family. See HSA contribution limits for 2027. This page covers the 2026 tax year.
Every spring the IRS publishes the following year's Health Savings Account figures, and every fall a lot of people fill out open-enrollment paperwork using last year's numbers. The 2026 limits went up across the board, so if you're still budgeting off 2025 figures you're leaving contribution room — and tax deduction — on the table.
Here's the complete set of numbers, what each one actually governs, and the rules that trip people up.
For the 2026 tax year, you can contribute:
These come from IRS Revenue Procedure 2025-19. The catch-up amount is the one number that doesn't move — it's fixed at $1,000 in statute and isn't indexed to inflation, which is why it has stayed flat for years while everything else creeps upward.
Worth noting: the limit is a combined ceiling. It covers your payroll deferrals, any money your employer contributes on your behalf, and anything you deposit directly from a bank account. If your employer seeds your HSA with $1,000, your own maximum drops to $3,400 on self-only coverage.
You can't contribute to an HSA unless you're covered by a qualifying High-Deductible Health Plan. "High deductible" isn't a marketing term here — it's a specific IRS definition with its own thresholds, and those changed for 2026 too.
Minimum annual deductible:
Maximum out-of-pocket:
The out-of-pocket cap includes deductibles, copays, and coinsurance — but not premiums. A plan has to sit inside both windows to qualify: deductible at or above the minimum, out-of-pocket at or below the maximum. A plan with a $1,200 deductible isn't an HDHP no matter how expensive it feels, and a plan with a $25,000 out-of-pocket maximum isn't one either.
If you're comparing plans during open enrollment, this is the single thing to check first. Everything else about HSA planning is downstream of whether your plan actually qualifies.
The $1,000 catch-up is per person, but it has to go into that person's HSA. Two spouses who are both 55+ can contribute $1,000 extra each — but they need two separate HSAs to do it. You cannot stack $2,000 of catch-up into one spouse's account.
This surprises people, because the $8,750 family limit can be deposited entirely into a single spouse's HSA if you want. The base limit is flexible; the catch-up is not.
If you're in that situation and only one of you has an account, opening a second HSA is usually worth the ten minutes of paperwork.
Normally your contribution limit is prorated by how many months you were HSA-eligible. Become eligible on July 1, and you'd get half the annual limit.
The last-month rule overrides that: if you're HSA-eligible on December 1, the IRS lets you contribute the full annual amount for that year, regardless of when you became eligible.
The catch is the testing period. To keep that full contribution, you have to remain HSA-eligible for all twelve months of the following year. Fail that — you switch to a non-HDHP plan in June, say, or enroll in Medicare — and the excess gets pulled back into your taxable income and hit with an additional 10% tax.
The last-month rule is genuinely useful if your situation is stable. It's a liability if you're likely to change plans, change jobs into non-HDHP coverage, or turn 65 next year.
This is one of the friendliest rules in the tax code and a lot of people don't know it. HSA contributions for a given tax year can be made until the tax filing deadline for that year — typically April 15 of the following year — not December 31.
So you have until roughly April 15, 2027 to finish funding your 2026 HSA. If you do make a contribution in that window, tell your custodian which tax year it applies to. Otherwise they'll default to coding it as a current-year contribution, and untangling that later is tedious.
This gives you a real planning lever: you can do your taxes, see your actual tax bill, and then decide whether to top off your HSA to reduce it.
Excess contributions are subject to a 6% excise tax for every year they stay in the account. That's not a one-time penalty — it repeats annually until you fix it.
The fix is to withdraw the excess, plus any earnings it generated, before your tax filing deadline. Handled in time, you pay income tax on the earnings and avoid the 6% entirely. Most custodians have a specific "excess contribution removal" form for this; using a normal withdrawal form instead will get it miscoded.
Overcontribution happens most often to people who change jobs mid-year and end up with two employers both making contributions, or to couples who each fund to the family maximum without realizing it's a household limit.
The limits are ceilings, not targets. Maxing out an HSA makes the most sense when you can afford to leave the balance invested rather than spending it down each year — that's where the triple tax advantage actually compounds into something meaningful.
If you're going to withdraw the money for this year's expenses anyway, an HSA still saves you the income tax on the way in, which is a real benefit. But the account's biggest edge comes from time in the market, which is why investing the balance rather than parking it in cash matters so much.
The version of this that quietly beats both approaches: contribute the max, invest it, pay medical bills out of pocket, and reimburse yourself years later once the balance has grown. That's the shoebox strategy, and the only thing it requires is that you still have the receipts when you decide to cash them in.
| Self-only | Family | |
|---|---|---|
| 2026 contribution limit | $4,400 | $8,750 |
| 2025 contribution limit | $4,300 | $8,550 |
| Catch-up (55+) | +$1,000 | +$1,000 per spouse |
| HDHP minimum deductible | $1,700 | $3,400 |
| HDHP out-of-pocket max | $8,500 | $17,000 |
Bookmark the numbers you need, check that your plan actually qualifies as an HDHP, and remember you have until tax day to finish funding the year. The receipts you keep along the way are what turn those contributions into tax-free money later — SaveMyHSA exists to make sure they're still there when you need them.
