The IRS sets annual limits that depend on your coverage type

The amount you can contribute to an HSA each year is set by the Internal Revenue Service and changes annually. For 2024, the limits are $4,150 for individual coverage and $8,300 for family coverage. These numbers shift most years, so you need to check the current limit before you contribute.

The limit applies to all contributions combined—money you put in, money your employer puts in, and money anyone else puts in on your behalf all count toward the same ceiling. If you exceed the limit, you owe taxes on the overage plus a 6% penalty tax, so it matters that you track what goes in.

You can only contribute if you are enrolled in a high-deductible health plan (HDHP). The moment you switch to a different type of health insurance, you stop being able to contribute, though you can still spend money that is already in the account.

Key Takeaways

  • The 2024 contribution limit is $4,150 for self-only coverage and $8,300 for family coverage, and these limits change each year.
  • Contributions from you, your employer, and anyone else all count toward the same annual limit.
  • You can only contribute while you are enrolled in an HDHP; switching to other insurance stops new contributions when ready.
  • If you turn 55, you can add an extra $1,000 per year as a catch-up contribution, and this amount does not change annually.

How employer contributions affect your personal limit

If your employer contributes to your HSA, that money counts against your annual limit. This means if your employer puts in $2,000 and you want to contribute $2,150 (the remaining room under the $4,150 individual limit), you can only add $2,150 yourself, not the full amount you might have wanted.

You need to ask your employer or benefits administrator how much they plan to contribute before the year starts. Some employers contribute a set amount; others match a percentage of what you contribute. Knowing their number lets you plan how much to set aside from your own paycheck.

Employer contributions are not taxed as income to you, and they do not reduce the amount your employer can deduct. This is one of the tax advantages of HSAs, but it only works if you stay within the total limit.

The catch-up contribution for people 55 and older

If you turn 55 during the year, you can add an extra $1,000 to your HSA on top of the regular limit. This is called a catch-up contribution, and it is the only part of the HSA limit that does not change year to year.

You can make catch-up contributions every year after you turn 55, as long as you remain enrolled in an HDHP. The $1,000 is separate from the regular limit, so a 55-year-old with individual coverage can contribute $4,150 plus $1,000 for a total of $5,150 in 2024.

If you are married and both spouses are 55 or older and have family coverage, you each get your own $1,000 catch-up, so the household can contribute $8,300 plus $2,000 total.

What happens if you contribute too much

If you put more money into your HSA than the annual limit allows, the IRS treats the overage as a taxable distribution. You owe income tax on the excess amount, and you also owe a 6% penalty tax on it for each year it sits in the account uncorrected.

If you discover an overage before you file your tax return for that year, you can withdraw the excess and the earnings on it, and you will owe tax only on the earnings, not the excess itself. This is called a corrective distribution, and it is the fastest way to fix the problem.

If you do not catch it until after you file, you will need to file an amended return. The penalty applies for each year the money stays in the account, so the sooner you fix it, the less you owe. Keep records of all contributions—yours, your employer's, and any from family members—so you can spot overages quickly.

Tracking contributions across multiple sources

Your HSA custodian (the bank or financial company holding the account) sends you a statement each quarter or year showing deposits. If money comes from your paycheck, your employer's benefits system, and a family member's gift all in the same year, you need to add them all together to see if you have hit the limit.

Some employers use payroll deduction, which makes it straightforward to see your contribution on each pay stub. Others make lump-sum deposits. Family members or friends who want to contribute should send the money directly to your HSA custodian, not to you, to avoid confusion about whether it counts as income.

If you change jobs mid-year, contributions from your old employer and new employer both count toward the same annual limit. You are responsible for tracking the total, so contact both employers' benefits teams to confirm what each contributed.

How limits change and where to find the current year's number

The IRS announces the new HSA contribution limits each year, usually in late spring, for the following calendar year. The limits are tied to inflation and round to the nearest $50, so they do not always change, but they often do.

You can find the current year's limits on the IRS website under "HSA contribution limits" or on your HSA custodian's website. Your employer's benefits team should also have the number available when open enrollment starts. Do not assume last year's limit is still in effect.

If you are self-employed or have no employer HSA plan, you can open an individual HSA through a bank, credit union, or investment firm. The contribution limit is the same whether your HSA is through an employer or opened on your own.

Frequently Asked Questions

Can I contribute to an HSA if my employer already maxed out their contribution?

No. Once the combined total of employer and employee contributions hits the annual limit, you cannot add more. If your employer contributes the full limit, you have no room to contribute yourself that year. You can still spend the money already in the account.

What if I lose my HDHP coverage mid-year?

You can no longer contribute for the remainder of that year. Contributions are only allowed while you are enrolled in an HDHP. Money already in the account stays there and can be spent anytime, but new contributions stop when ready when your coverage changes.

Do I report my HSA contributions on my tax return?

If you contribute through payroll deduction, your employer reports it and it does not appear on your tax return. If you contribute directly to the HSA yourself, you report it on Form 8889 when you file. Your HSA custodian sends you a statement showing what you contributed.

Can my spouse contribute to my HSA?

Yes, but their contribution counts toward your annual limit. If you have individual coverage with a $4,150 limit and your spouse contributes $1,000, you can only add $3,150 yourself. The money goes into your account, not theirs.

What if I turn 55 mid-year?

You can make the catch-up contribution for any month in which you are age 55 or older and enrolled in an HDHP. If you turn 55 in June, you can add the $1,000 catch-up for the remainder of that year, even though you were not 55 for the whole year.
