HSA Contribution Limits for 2026: Self-Only, Family and Catch-Up

For 2026, you can put up to $4,400 into an HSA with self-only high-deductible health plan (HDHP) coverage, or $8,750 with family coverage. If you are 55 or older, you can add a $1,000 catch-up on top. The limit covers everything that goes into the account in a year, including your employer's deposits and money taken from your paycheck, so both draw on the same allowance.

Those are the figures IRS Publication 969 gives for 2026. The increase over 2025 is small: $100 on the self-only limit and $200 on the family limit. The rules that cause trouble are about how the pieces add up, so most of this page covers that.

The 2026 limits next to 2025

The catch-up goes to anyone who is 55 or older at the end of the tax year. Publication 969 describes it as an increase to your contribution limit, not a separate account, so it sits in the same HSA as everything else you contribute. For the health FSA side of the choice, see HSA vs FSA.

Divide the annual limit by 12 and you get the monthly room: about $366.67 for self-only coverage and $729.17 for family. Set a payroll deduction against those monthly figures. That keeps you from using up the year's room in the first few paychecks, and it leaves you a clear number to check against your employer's deposit.

Family coverage and two catch-ups

A family HDHP has one limit for the whole plan, $8,750 for 2026. Unless the spouses agree on a different split, the IRS divides that limit equally between them. Each spouse who is 55 or older adds the catch-up, but the catch-up has to go into that spouse's own HSA, not the other spouse's. Publication 969 says each spouse must make the additional contribution to their own account.

Take a couple who are both 55 or older, on one family plan, who split the limit equally. Each receives $4,375 of the family limit and adds the catch-up, so each can contribute $5,375. Together that is $10,750 for 2026. If only one spouse is 55 or older, the household total is $9,750: the family limit plus one catch-up.

The split is worth settling in writing before the year starts. A couple that wants one account to take more than half the family limit has to agree on that division, and the default equal split applies if they do not.

How employer deposits and payroll deductions count

Money your employer puts into your HSA is not income to you. Publication 969 also says those contributions count toward the annual limit, and that includes amounts paid in through a cafeteria plan, the usual route for a payroll deduction. The employer's deposit and your paycheck deduction are added together and checked against one number.

Consider a 40-year-old with self-only coverage. The employer deposits $1,200 over the year, and the worker elects $200 a month from pay, which is $2,400. Together that is $3,600, leaving $800 of room. Suppose the worker then sends $1,000 from a bank account. That is $200 over the limit, and the 6% excise tax on that excess is $12.

The fix is simple arithmetic done early. Ask HR when the employer deposit is made and how much it will be, then set the payroll election to the room that is left. A deposit that arrives late in the year can use up room you assumed was still open, so confirm the schedule before you pick a deduction.

Starting HDHP coverage in the middle of the year

Normally the limit is worked out month by month. You get one twelfth of the annual limit for each month you are eligible on the first day of that month. Someone whose HDHP starts on October 1 is eligible in October, November and December, so the monthly math gives 3/12 of the self-only limit, or $1,100.

The last-month rule changes that math. If you are eligible on December 1, the IRS treats you as eligible for the entire year, so the same October starter can contribute the full annual limit. The trade-off is the testing period. It begins in the last month of the year, and you must stay eligible through it. Publication 969 says that if you fail the testing period, you must include an amount in income and pay a 10% additional tax on that amount. Work out the exact figure with a tax adviser before you rely on the full limit.

If you change jobs during the year, the limit still covers every HSA you hold, including deposits from the old employer. Check the coverage start date on the new plan, then check what the old employer deposited before you decide how much to put in.

Going over the limit

Contributions above the limit carry a 6% excise tax. Publication 969 says you generally must pay that tax on excess contributions. The employer example shows the scale: $200 over the limit costs $12 in excise tax. The bigger risk is missing the excess altogether, because an employer deposit and a payroll deduction can each look reasonable on their own.

Review the year's deposits before the tax deadline. If you find an excess, ask your custodian how to correct it before you file.

The 2026 contribution deadline

Publication 969 gives the deadline for 2025 contributions as April 15, 2026, the filing date for that return. The same pattern puts the 2026 deadline at April 15, 2027. Contributions made in early 2027 can count toward 2026, which helps if your payroll deductions fell short.

You report HSA contributions on Form 8889. The IRS says that form covers contributions made on your behalf, including employer contributions, so the employer deposit appears on the same form as your own money.

Investing the balance

The limit applies to what goes in each year, not to the balance. Investment returns do not count against it, so the account can grow well past the family limit without breaking any rule. Once the balance is large, the investing choices matter more than the limit does.

For investing the balance, see our best robo advisors guide and best free investing apps guide, and confirm that a platform accepts HSA accounts before you open one. The Wealthfront vs Betterment comparison walks through two automated platforms side by side. For the cash side of the decision, the where to put cash guide covers the savings choices next to the HSA.

Checklist before you change a payroll election

• Confirm your coverage type on the first day of each month, because the limit follows the plan you hold.
• Add the employer deposit to your planned payroll total before you choose a deduction.
• Check whether you are 55 or older by the end of the tax year, and whether your spouse is.
• Keep a running total from the custodian statement, not from memory.

Your HSA custodian and your employer's benefits team can confirm each figure against your plan. Their records, not this page, govern your account.

What we checked

We checked IRS Publication 969 on October 10, 2026. The 2026 limits come from its tips for that year, the 2026 HDHP figures from its HDHP table, and the 2025 figures from its main text. The IRS Form 8889 page confirms how employer contributions are reported. The worked examples use these figures and simple arithmetic. They are illustrations, not forecasts.

This page is general information, not personalized financial advice. Confirm your limit, your employer deposit and your payroll election with your benefits team and your HSA custodian before you change either.

FAQ

What is the HSA contribution limit for 2026?

For 2026, the limit is $4,400 with self-only HDHP coverage and $8,750 with family coverage. Account holders 55 or older can add a $1,000 catch-up on top. Employer deposits count toward the same limit, according to IRS Publication 969.

Do employer contributions count toward the HSA limit?

Yes. Money your employer puts into your HSA counts toward the annual limit, and it is not counted as income to you. Payroll deductions made through a cafeteria plan draw on the same allowance, so add the two before you choose a deduction.

Can both spouses take the catch-up on one family plan?

Yes, if both are 55 or older, but each catch-up goes into that spouse's own HSA. The family limit is split equally between them unless they agree otherwise. Two eligible spouses on a family plan can contribute $10,750 together for 2026.

What happens if I contribute more than the HSA limit?

The excess is subject to a 6% excise tax, according to IRS Publication 969. For example, $200 over the limit costs $12 in excise tax. Ask your custodian how to correct an excess before you file your return.

How much can I contribute if my HDHP starts in October?

Under the monthly rule, three months of self-only eligibility gives $1,100 of room. If you are eligible on December 1, the last-month rule can allow the full annual limit for the year, as long as you stay eligible through the testing period that follows.
