How Much You Can Put Into an HSA Each Year

HSA contributions are the money you put into your Health Savings Account, either through payroll deductions or direct deposits, up to a yearly limit set by the IRS.

The limit changes each year and depends on whether your health plan covers just you or your whole family. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These numbers increase slightly most years to keep pace with inflation, so check the current year's limit before you contribute.

You can contribute money at any time during the year, but most people do it through their employer's payroll system — the money comes out of your paycheck before taxes are taken. If you don't have an employer HSA plan, you can open an HSA on your own and deposit money directly. Either way, the total you put in across all accounts cannot exceed the yearly limit, or you'll owe taxes and penalties on the overage.

Key Takeaways

The IRS sets a yearly contribution limit that varies by whether you have individual or family health coverage, and the limit increases most years.
You can contribute through payroll deductions, direct bank transfers, or checks, but the total from all sources cannot exceed the yearly limit.
Contributions made through payroll are taken out before income tax and Social Security tax are calculated, lowering your taxable income for the year.
If you contribute more than the limit, you must report the overage on your tax return and pay income tax plus a 20 percent penalty on the excess amount.

How the yearly contribution limit works

The IRS publishes the HSA contribution limit each year, usually in March or April. The limit applies to the calendar year — January through December — and is the same whether you contribute all at once or spread payments throughout the year. If you change health plans mid-year or lose coverage, your limit may be reduced proportionally, so the timing of coverage changes matters.

The limit covers all contributions you make to any HSA you own. If you have two HSAs at different banks, the total across both accounts still cannot exceed the yearly limit. This rule catches people by surprise when they switch banks and forget to close the old account — they end up over the limit without realizing it.

Contributing through payroll versus on your own

If your employer offers an HSA, payroll contributions are usually the simplest route. The money comes out of your paycheck before federal income tax, Social Security tax, and Medicare tax are calculated. This means a $200 payroll contribution might only reduce your take-home pay by $140 to $150, depending on your tax bracket. The employer also cannot take payroll taxes out of HSA contributions, so you get an immediate tax savings.

If you don't have an employer HSA or want to contribute beyond what your employer offers, you can open an HSA on your own at a bank or financial institution and deposit money directly. These contributions are not automatically tax-deductible — you have to claim them on your tax return (Form 8889) to get the tax break. Self-employed people and those with individual health plans often use this route.

What happens if you contribute too much

If your total contributions exceed the yearly limit, the IRS treats the overage as taxable income. You must report it on Form 8889 when you file your tax return, and you'll owe income tax on the excess amount at your regular tax rate. On top of that, you pay a 20 percent penalty on the overage — so a $500 overage could cost you $100 in penalties plus income tax.

The penalty applies only to the excess, not to your entire HSA balance. If you catch the mistake before filing your tax return, some HSA providers will let you withdraw the overage and the earnings on it without penalty, but you still owe income tax on the earnings. It's worth asking your HSA provider about this option if you realize you've gone over.

Catch-up contributions if you're 55 or older

If you turn 55 during the year, you can contribute an extra $1,000 on top of the regular limit — this is called a catch-up contribution. You're allowed one catch-up contribution per year starting the year you turn 55 and continuing through the year you turn 65 and enroll in Medicare. The catch-up amount stays $1,000 and doesn't increase with inflation.

Catch-up contributions follow the same rules as regular contributions: they can come through payroll or direct deposit, and they count toward your total HSA savings. If you have family coverage and both you and your spouse are 55 or older, you can each make a separate catch-up contribution, for a combined extra $2,000.

Contribution deadlines and timing

You can make HSA contributions at any point during the year, and you have until the tax filing deadline — usually April 15 of the following year — to make contributions for the previous year. This means you can contribute to your 2024 HSA as late as April 15, 2025, and it will count toward your 2024 limit. Your HSA provider will report all contributions to the IRS on Form 5498-SA, so keep your own records to make sure the amounts are correct.

If you're contributing through payroll, your employer sets the contribution schedule — usually spread across each paycheck. If you're self-employed or contributing on your own, you control the timing and can deposit a lump sum or make regular transfers.

How contributions interact with your health plan

You can only contribute to an HSA if you're enrolled in a high-deductible health plan (HDHP). If you drop your HDHP coverage mid-year, you can no longer make contributions for the rest of that year, though you keep the money already in the account. If you switch to a non-HDHP plan and then switch back to an HDHP later in the year, your contribution limit is reduced based on the months you had HDHP coverage.

If you have other health coverage — like Medicare, Medicaid, or a spouse's plan that isn't an HDHP — you're not allowed to contribute to an HSA. The IRS considers this disqualifying coverage, even if you're not actually using that plan. This rule trips up people who have Medicare and an old HSA; once you enroll in Medicare, you must stop making HSA contributions.

Frequently Asked Questions

Can I contribute to an HSA if I'm self-employed?

Yes. You need to be enrolled in an HDHP, but you can open an HSA on your own and make direct contributions. You claim the contributions as a deduction on your tax return (Form 1040, line 12) to get the tax break. You're not required to have an employer to have an HSA.

What if my employer contributes to my HSA — does that count toward my limit?

Yes. Employer contributions count toward your yearly limit, so if your employer puts in $1,000 and you contribute $2,000, your total is $3,000. Make sure you know how much your employer is contributing so you don't accidentally go over the limit with your own deposits.

Can I make HSA contributions after I turn 65 and enroll in Medicare?

No. Once you enroll in Medicare, you're no longer allowed to make new HSA contributions. You can still withdraw money from your HSA to pay for medical expenses, and the money rolls over year to year, but you cannot add to it.

If I contribute too much, can I get the money back without a penalty?

You can withdraw the excess before you file your tax return, but you'll still owe income tax on any earnings the excess generated. Some HSA providers make this process easy; others require you to request it in writing. Contact your HSA provider as soon as you realize you've gone over.
