How Much You Can Put Into Your HSA Each Year

The annual contribution limit depends on your health plan type and family size

The IRS sets a maximum amount you can contribute to a Health Savings Account each year. For 2024, the limit is $4,150 if you have individual coverage, or $8,300 if you have family coverage. These limits change most years, so you will need to check the current year's figure before you contribute.

Your employer may contribute to your HSA as well. Employer contributions count toward your limit, not in addition to it. If your employer puts in $2,000 and you put in $2,000, you have reached your $4,150 individual limit for the year. You cannot exceed the total even if the money comes from different sources.

The limit applies to the calendar year, January through December. Contributions made by April 15 of the following year can be counted toward the previous year's limit if you file your taxes by that date, but this is rare and requires specific paperwork.

Key Takeaways

• The 2024 HSA contribution limit is $4,150 for individual coverage and $8,300 for family coverage, and these amounts increase most years.
• Money your employer contributes counts toward your limit, so you must track both employer and employee contributions together.
• If you turn 55 during the year, you can contribute an extra $1,000 as a catch-up contribution in that same year.
• Exceeding your limit means you owe taxes on the overage plus a 6 percent penalty each year it remains in the account.
• You can contribute less than the limit or nothing at all — there is no requirement to max out your HSA.

Catch-up contributions if you are 55 or older

Once you turn 55, you can contribute an additional $1,000 per year on top of the standard limit. This is called a catch-up contribution. If you have family coverage and turn 55, you can contribute $8,300 plus $1,000, for a total of $9,300 that year.

You can make catch-up contributions every year after you turn 55, as long as you remain enrolled in an HSA-may be able to access health plan. The $1,000 catch-up amount does not change year to year, even though the base limit does.

What happens if you contribute too much

If you put more money into your HSA than the limit allows, the excess amount is subject to income tax plus a 6 percent excise tax. The 6 percent penalty applies each year the overage stays in the account. For example, if you over-contribute by $500 and do not remove it, you owe 6 percent of $500 ($30) in tax that year, and another $30 the next year if it remains.

You can fix an overage by withdrawing the excess amount plus any earnings on that money before your tax filing deadline. The withdrawal itself is not taxed, but you do owe tax on the earnings. If you discover the overage after you file your taxes, you can still withdraw it, but you will need to file an amended return.

Employer contributions and how they affect your limit

When your employer contributes to your HSA, that money counts dollar-for-dollar toward your annual limit. If your employer contributes $3,000 to your individual HSA, you can only contribute $1,150 more that year (assuming the 2024 limit of $4,150).

Some employers make contributions in a lump sum at the start of the year. Others contribute monthly or per paycheck. Either way, you need to track the total to know how much room you have left. Your HSA provider or your employer's benefits department can tell you how much has been contributed so far in the year.

If you change jobs mid-year, contributions from both employers count toward the same annual limit. If your first employer contributed $2,000 and your new employer contributes $2,000, you have reached the limit and cannot contribute any of your own money that year.

Contributing less than the maximum

You do not have to contribute the full amount allowed. Many people contribute what they can afford or what matches their expected health care costs. Contributing $500, $1,000, or any amount below the limit is perfectly acceptable and carries no penalty.

Some people use their HSA only for current-year medical expenses and do not try to build a large balance. Others contribute the maximum every year and let the money grow for retirement. Both approaches are valid — the limit is a ceiling, not a target.

How to track your contributions throughout the year

Your HSA provider sends you statements showing deposits, withdrawals, and your current balance. Keep these statements to verify that contributions from your employer and your own deposits match what you intended.

If you contribute through payroll deductions, your pay stub will show the amount taken out each period. Add up these amounts to see your year-to-date total. Then add any employer contributions shown on your benefits statement. The sum should not exceed your annual limit.

If you discover a mistake before the end of the year, you can adjust your remaining contributions. If you find it after the year ends, you have until your tax filing deadline to withdraw the overage.

Frequently Asked Questions

Can I contribute to my HSA if I have not used it yet this year?

Yes. You can contribute to your HSA whether you have used it or not. The contribution limit and the ability to use the money are separate. You can build a balance and use it whenever you need it, or use it as you go.

What if my employer changes my health plan mid-year?

If you switch from family coverage to individual coverage (or vice versa) mid-year, your contribution limit changes on the date the new plan starts. You can contribute the prorated amount for each coverage type. Your HSA provider can calculate the exact limit for your situation.

Do I have to contribute the same amount every year?

No. Your contribution can be different each year. You might contribute $2,000 one year and $4,000 the next. The only requirement is that you do not exceed the annual limit for that specific year.

Can I contribute to my HSA after I turn 65?

No. Once you enroll in Medicare, you can no longer make contributions to your HSA. You can still withdraw money from it for may have access to medical expenses, but you cannot add new money. This applies even if you delay Medicare enrollment — the rule is based on enrollment, not age.

What if my employer and I both contribute — do I need to report it somewhere?

Your employer reports their contributions on Form 5498-SA, which goes to the IRS and to you. You report your own contributions on Form 8889 when you file your taxes. Your HSA provider sends you the information you need to complete this form.
