How Much You Can Put Into an HSA Each Year

Annual contribution limits are set by the IRS and depend on your coverage type

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 — the IRS adjusts them for inflation — so you will need to check the current year's limit before you contribute.

Your contribution limit depends on which month you enroll in an HSA-may be able to access health plan. If you sign up mid-year, you can contribute a prorated amount for the months you are covered. The IRS counts contributions made through April 15 of the following year as part of the current tax year, so you have time after the calendar year ends to catch up.

You cannot contribute more than your plan allows, even if the IRS limit is higher. Some employers cap HSA contributions below the federal maximum, so check your plan documents or ask your benefits administrator what your specific limit is.

Key Takeaways

• The 2024 IRS limit is $4,150 for individual coverage and $8,300 for family coverage, and these amounts change yearly for inflation.
• If you enroll in an HSA-may be able to access plan partway through the year, you can contribute only for the months you are covered, calculated as a fraction of the annual limit.
• You have until April 15 of the following year to make contributions that count toward the current tax year.
• Your employer's plan may set a lower contribution limit than the IRS allows, so verify your actual cap with your benefits office.
• Contributions over the limit trigger a 6 percent excise tax on the excess amount each year it remains in the account.

How the IRS calculates prorated limits for mid-year enrollment

If you become covered by an HSA-may be able to access plan after January 1, you cannot contribute the full annual amount. Instead, divide the annual limit by 12 and multiply by the number of months you are covered. For example, if you enroll in family coverage on July 1, 2024, you are covered for seven months (July through December). The 2024 family limit is $8,300, so your limit is $8,300 ÷ 12 × 7 = $4,842.

The IRS counts a month as covered if you are enrolled on the first day of that month. If you enroll on July 2, you do not count July. If you enroll on July 1, you do. This matters because even one month can shift your limit by several hundred dollars.

There is one exception: if you enroll in an HSA-may be able to access plan on December 1 or later, you can contribute the full annual amount for that year. This rule is called the last-month rule, and it exists to prevent people from losing contribution room because they switched plans late in the year. However, if you use the last-month rule, you must stay enrolled in an HSA-may be able to access plan through December 31 of the following year, or you will owe taxes and a 20 percent penalty on the excess contributions.

Employer contributions count toward your limit

Money your employer puts into your HSA counts against your annual limit. If your employer contributes $2,000 and you contribute $2,000, you have reached the $4,000 mark toward the individual limit. You cannot then contribute another $4,150 on top of that.

Some employers contribute a fixed amount each year. Others make contributions only if you enroll in a high-deductible health plan, or they match a portion of what you contribute. Check your benefits summary or ask your HR department how much your employer plans to contribute, so you know how much room you have left to contribute yourself.

Employer contributions are not taxed as income to you, and they reduce the amount you can contribute without triggering the excess contribution penalty. If your employer maxes out the limit on your behalf, you cannot add any of your own money that year.

What happens if you contribute too much

If you put more money into your HSA than the IRS limit allows, you owe a 6 percent excise tax on the excess amount. This tax applies every year the excess stays in the account. For example, if you over-contribute by $500 and do not withdraw it, you owe $30 in tax that year. If the $500 sits there for three years, you owe $30 each year.

You can fix an over-contribution by withdrawing the excess plus any earnings on that money. The earnings are taxed as income, but the excess itself is not taxed again. You have until the tax filing deadline (usually April 15) to withdraw the excess for the previous year and avoid the penalty.

If you discover an over-contribution after the deadline, you can still withdraw it, but you will owe the 6 percent tax for each year it remained in the account. Some HSA providers offer a correction process that can reduce or eliminate the penalty if you acted in good faith, so contact your provider if you realize you have over-contributed.

Catch-up contributions if you are 55 or older

Once you turn 55, you can contribute an additional $1,000 per year to your HSA, on top of the regular limit. This is called a catch-up contribution, and it is designed to help people save more for health care in retirement. If you have individual coverage and are 55, your 2024 limit is $4,150 + $1,000 = $5,150. If you have family coverage, it is $8,300 + $1,000 = $9,300.

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 plan. The catch-up amount does not change with inflation — it stays at $1,000 annually. If you are married and both spouses are 55 or older and have separate HSAs, each of you can make a $1,000 catch-up contribution.

Catch-up contributions count toward your total limit, just like regular contributions. If your employer contributes money to your account, that does not reduce the catch-up room available to you — the catch-up is separate.

Tracking contributions across employers or multiple HSAs

If you change jobs or have more than one HSA, you are still limited to one annual contribution total across all accounts. The IRS does not track this for you — it is your responsibility to make sure you do not exceed the limit when you add up contributions from all sources.

For example, if you work two part-time jobs and both offer HSA-may be able to access plans with employer contributions, you must coordinate with both employers to ensure the combined total does not exceed the annual limit. If one employer contributes $2,000 and the other contributes $1,500, you can contribute only $650 to stay within the $4,150 individual limit.

If you leave a job mid-year and the employer has already contributed their annual amount, you cannot contribute that full amount yourself. Some employers will reduce their contribution if you leave early, but others will not. Ask your departing employer and your new employer how much each has contributed before you add your own money.

How contribution limits differ from spending limits

The annual contribution limit is separate from how much you can spend from your HSA. Once money is in your account, you can spend it all in one year if you have medical expenses that large. There is no annual spending limit — only a limit on how much you can put in.

This matters because HSAs are designed to let you save money over time. You might contribute $4,150 one year and spend only $1,000, leaving $3,150 in the account to roll over to the next year. That carryover balance stays in your account indefinitely and can be spent whenever you have a may have access to medical expense, even decades later.

Some employers offer limited-purpose FSAs or dependent care FSAs alongside HSAs. These have separate contribution limits and different spending rules. Do not confuse the HSA limit with those account limits — they are independent of each other.

Frequently Asked Questions

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

Yes. Your contribution limit is not affected by whether you have met your deductible or how much you have spent on medical care. You can contribute the full amount regardless of your deductible status or current health expenses.

What if my employer changes the HSA plan mid-year?

If your employer switches to a different HSA provider or plan, your contribution limit for the year does not change. The limit is based on your coverage type (individual or family) and the months you are enrolled, not on which specific plan you use. Contributions made to the old plan and new plan both count toward your annual total.

Do I have to contribute the maximum amount every year?

No. You can contribute any amount up to the limit, including zero. If you do not need to save for medical expenses that year, you can skip contributions entirely. There is no requirement to use the full limit, and unused money rolls over to future years.

Can I change my contribution amount during the year?

If you contribute through payroll deductions, you can usually change your contribution amount during open enrollment or if you have a may have access to life event (marriage, birth, job change, loss of coverage). If you contribute directly to your HSA, you can deposit money whenever you want, as long as the total does not exceed your annual limit.

What if I turn 55 mid-year?

You can make the $1,000 catch-up contribution starting in the month you turn 55. If you turn 55 in June, you can add the catch-up amount to your contributions for that year. The catch-up is not prorated — you get the full $1,000 even if you turn 55 late in the year.
