2024 HSA Contribution Limits and How They Work

The 2024 HSA contribution limit depends on your coverage type

For 2024, you can contribute up to $4,150 if you have individual coverage or $8,300 if you have family coverage under a high-deductible health plan. These are the amounts the IRS allows you to set aside in an HSA during the calendar year. If you are 55 or older, you can add an extra $1,000 catch-up contribution on top of these limits.

The limit applies to the total of all contributions you make across all HSAs you own — you cannot split the limit between multiple accounts to contribute more. If you are married and both spouses have HSAs, each person gets their own separate limit.

These limits change most years. The IRS announces the new amounts in the fall for the following year, and they are based on inflation. If your plan year runs on a calendar different from January through December, your plan administrator will tell you which year's limits apply to your contributions.

Key Takeaways

• Individual coverage HSA holders can contribute $4,150 in 2024; family coverage holders can contribute $8,300.
• If you are 55 or older, you can add $1,000 more to either limit as a catch-up contribution.
• The limit covers all your HSA contributions combined, even if you have more than one HSA account.
• Contributions made after December 31, 2024 count toward the 2025 limit, not 2024, unless you file taxes late and make a prior-year contribution by the tax deadline.

How the contribution limit works if you change coverage mid-year

If you switch from individual to family coverage (or vice versa) partway through 2024, the limit changes on the date your coverage changes. You are allowed to contribute a prorated amount for each coverage type — the full limit divided by 12 months, then multiplied by the number of months you had that coverage.

For example, if you had individual coverage for six months and family coverage for six months in 2024, you would calculate: ($4,150 ÷ 12 × 6) + ($8,300 ÷ 12 × 6). Your employer or HSA custodian can help you figure the exact amount. If you contribute more than the prorated limit, you will owe taxes and a 20 percent penalty on the overage, so it is worth getting this right before you contribute.

The same prorated rule applies if you lose HSA coverage during the year — for instance, if your plan stops being high-deductible or you leave your job. You can only contribute for the months you were actually covered.

Employer contributions count toward your limit

Money your employer puts into your HSA reduces the amount you are allowed to contribute yourself. If your employer contributes $2,000 to your family HSA in 2024, you can only contribute $6,300 more ($8,300 − $2,000) to stay within the limit.

Your employer's contributions are reported on your pay stub or in a separate statement. Some employers contribute the same amount for all employees; others base it on salary or coverage type. Either way, you need to know the total before you decide how much to contribute yourself. If you are unsure, ask your benefits administrator or check your HSA account — most custodians show employer contributions clearly.

If you contribute too much when combined with your employer's contribution, you have until the tax deadline (usually April 15 of the following year) to withdraw the overage. The overage itself is not taxed, but any earnings on it are taxed and penalized.

Catch-up contributions for people 55 and older

If you turn 55 at any point during 2024, you can contribute an additional $1,000 on top of the standard limit. This is called a catch-up contribution and is meant to help people save more as they approach retirement.

You become may be able to access on the first day of the month in which you turn 55. If you turn 55 in June, you can make catch-up contributions starting in June. You do not have to wait until January of the next year. The catch-up amount is the same whether you have individual or family coverage.

The catch-up contribution is separate from the main limit, so it does not reduce the amount you can contribute under the standard rule. If you are married and both spouses are 55 or older, you each get your own $1,000 catch-up, for a total of $2,000 extra across both accounts.

When you can make contributions and how to avoid penalties

You can contribute to your HSA at any time during the year, but contributions made after December 31, 2024 are treated as 2025 contributions. The one exception is if you file your 2024 tax return late — you then have until the tax deadline to make a 2024 contribution, even if it is already 2025. This is called a prior-year contribution, and you must specify on your tax return that it is for 2024, not the current year.

If you contribute more than the limit for 2024, the IRS charges a 6 percent excise tax on the overage each year it stays in the account. For example, if you over-contribute by $1,000 and do not withdraw it, you owe $60 in tax that year. If it sits there for two years, you owe $120 total. The best move is to withdraw any overage as soon as you notice it, ideally before you file taxes.

Your HSA custodian (the bank or financial company that holds your account) is responsible for tracking contributions and flagging overages. Many send year-end statements showing total contributions. If you have contributions from an employer, a payroll deduction, and a personal deposit, make sure you add them all up before contributing more.

How contribution limits differ from spending limits

The contribution limit is separate from how much you can spend from your HSA. There is no limit on how much you can withdraw and spend on may have access to medical expenses — dental, vision, prescriptions, deductibles, copays, and many other costs. You could contribute $4,150 and spend $10,000 if you had that much in the account from prior years.

The contribution limit only controls how much new money you can put in during 2024. Once money is in the account, you can use it whenever you need it for may have access to expenses, with no annual spending cap. This is why HSAs are powerful for long-term health savings — you can accumulate money over many years and use it whenever the need arises.

Frequently Asked Questions

Can I contribute to an HSA if I have not met my deductible yet?

Yes. The contribution limit and the deductible are separate rules. You can contribute the full amount allowed even if you have not spent anything toward your deductible. The contribution limit only depends on whether you have an HSA-may be able to access plan; it does not depend on how much you have already spent.

What happens if my employer and I both contribute to my HSA in the same year?

The contributions are added together and must not exceed the annual limit. If your employer contributes $3,000 and you contribute $2,000, that is $5,000 total. For individual coverage in 2024, the limit is $4,150, so you would be over by $850. You would need to withdraw the overage before the tax deadline to avoid the 6 percent penalty.

Do HSA contributions reduce my taxable income?

If you contribute through payroll deduction, yes — the money comes out before taxes are calculated. If you contribute directly to the account yourself, you deduct it on your tax return (Form 8889). Either way, the contribution lowers your taxable income for the year.

Can I contribute to an HSA if I am on Medicare?

No. Once you enroll in Medicare, you are no longer may be able to access to contribute to an HSA, even if you still have an HSA-may be able to access plan through your job. You can continue to withdraw money from an existing HSA for may have access to expenses, but you cannot add new contributions.

What if I contribute too much by accident — can I get the money back?

Yes, but you need to act quickly. Withdraw the overage before you file your tax return for that year. The overage itself is not taxed, but any earnings it made while in the account are taxed as income and subject to a 20 percent penalty. The sooner you withdraw, the less it will have earned.
