You can contribute to an HSA if you are enrolled in a high-deductible health plan and meet IRS requirements

To contribute to a Health Savings Account, you must be covered by a high-deductible health plan (HDHP) as your primary insurance. You cannot be claimed as a dependent on someone else's tax return, and you cannot be enrolled in Medicare. You also cannot have other health coverage that is not an HDHP — with a few exceptions for specific plans like dental-only or vision-only coverage, which do not disqualify you.

The IRS sets the minimum deductible each year. For 2024, that minimum is $1,600 for individual coverage and $3,200 for family coverage. Your plan must also have an out-of-pocket maximum — the most you would pay in a year before insurance covers everything. For 2024, that maximum is $8,050 for individual coverage and $16,100 for family coverage. If your HDHP meets these thresholds, you become HSA-may be able to access the moment your coverage starts.

Your employer, you, or both of you together can contribute money to your HSA. Family members can also contribute on your behalf, though they cannot deduct the contribution on their own taxes — only you can claim the deduction. The total amount all contributors put in during a year cannot exceed the annual limit set by the IRS.

  • Your employer can contribute to your HSA, and you can contribute yourself up to the IRS annual limit.
  • Family members can contribute money to your HSA, but only you can claim the tax deduction for those contributions.
  • The IRS sets minimum deductible and maximum out-of-pocket thresholds each year; your plan must meet both to may have access to.

How employer contributions work

If your employer offers an HSA, they can contribute money directly into your account. This is common when you enroll in their HDHP during open enrollment. The employer contribution counts toward your annual limit but does not count as taxable income to you — it is a tax-free benefit.

Some employers contribute a fixed amount each year, such as $500 for individual coverage or $1,000 for family coverage. Others contribute a percentage of your deductible or out-of-pocket maximum. A few employers let you choose whether to receive the contribution as cash or as HSA funding; if you choose cash, that money is taxable income and does not count toward your HSA limit.

If you change jobs or leave your employer, your HSA stays with you. The account is yours to keep, and you can continue to contribute to it as long as you remain enrolled in an HDHP. Your new employer can also contribute to the same account if you set it up with them.

Your own contributions as an employee

You can contribute your own money to your HSA even if your employer also contributes. The combined total — employer plus employee — cannot exceed the annual limit. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. If you are 55 or older, you can contribute an additional $1,000 per year, called a catch-up contribution.

You can contribute through payroll deduction, which is the most common method. Money comes out of your paycheck before taxes, so you save on federal income tax, Social Security tax, and Medicare tax. You can also contribute directly to your HSA outside of payroll — by check, bank transfer, or credit card — and claim the deduction on your tax return when you file.

Contributions must be made by the tax filing deadline for the year you want to claim them. For the 2024 tax year, that deadline is April 15, 2025. If you contribute after you leave an HDHP, you can still contribute for the months you were covered, as long as you contribute by the deadline.

Family members and spousal contributions

Your spouse can contribute to your HSA if they are also enrolled in an HDHP. If you are both covered by a family HDHP, you share one annual limit — $8,300 for 2024 — and you can split that limit however you want between the two of you. Each of you can claim a deduction for your own contributions.

Other family members — adult children, parents, siblings — can also contribute money to your HSA, but they cannot claim a tax deduction for doing so. Only the account holder can claim the deduction. If a family member contributes, that money still counts toward your annual limit, so you need to track all contributions together to stay within the IRS cap.

There is no requirement that family members contribute. They can choose to help fund your account, but it is entirely voluntary. If they do contribute, make sure you document who gave the money and how much, so you can report it correctly on your taxes.

Who cannot contribute to an HSA

You cannot contribute if you are enrolled in Medicare, even if you also have an HDHP. Once you turn 65 and enroll in Medicare Part A or Part B, your HSA contributions must stop. You can still withdraw money from your HSA for may have access to medical expenses, but you cannot add new money.

You cannot contribute if you are claimed as a dependent on someone else's tax return, even if you have your own income and your own HDHP. This rule applies to adult children, elderly parents, and any other dependent. If you are no longer a dependent, you can start contributing the following year.

You cannot contribute if you have other health coverage besides an HDHP. Exceptions exist for specific plans: dental-only coverage, vision-only coverage, workers' compensation, disability insurance, long-term care insurance, and coverage for a specific disease or condition do not disqualify you. But if you have a traditional PPO, HMO, or any other comprehensive health plan alongside an HDHP, you lose HSA may be able to access.

You also cannot contribute if you are not actually enrolled in an HDHP. Simply having access to one through your employer is not enough — you must be actively covered by it.

Contribution limits and catch-up rules

The IRS sets annual contribution limits that change each year. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These limits include all contributions from all sources — your employer, you, your spouse, and any other family members.

If you turn 55 during the year, you can make a catch-up contribution of $1,000 for that year. You can continue making catch-up contributions each year after you turn 55, as long as you remain HSA-may be able to access. The catch-up amount is separate from the regular limit, so a 55-year-old with individual coverage can contribute up to $5,150 in 2024.

If you and your spouse are both covered by a family HDHP and you both turn 55 during the year, you can each make a $1,000 catch-up contribution, for a total of $2,000 extra. The family limit becomes $10,300 for that year.

If you contribute more than the annual limit, the excess is subject to a 6% excise tax each year it remains in the account. You also have to pay income tax on the excess. It is important to track your contributions carefully, especially if multiple people are contributing to your account.

What happens when you change health plans

If you switch from an HDHP to a different type of health plan, you can no longer contribute to your HSA starting the month your new coverage begins. However, you keep the money already in your account and can continue to withdraw it for may have access to medical expenses for the rest of your life.

If you move from one HDHP to another HDHP — whether through a job change or by switching plans — you remain HSA-may be able to access and can keep contributing without interruption. Your account follows you; you do not need to open a new one.

If you leave your job and go without health coverage for a period, you cannot contribute to your HSA during those months. Once you enroll in a new HDHP, you can resume contributions. If you are between jobs and want to make a contribution for the months you were covered, you can do so by the tax filing deadline.

Frequently Asked Questions

Can my adult child contribute to my HSA?

Yes, but they cannot claim a tax deduction for it. Any contribution they make counts toward your annual limit. Only you, as the account holder, can claim the deduction on your tax return. Make sure you track who contributed what so you can report it correctly.

What if I have both an HDHP and a spouse's traditional health plan?

You cannot contribute to an HSA if you have other comprehensive health coverage, even if it is through your spouse's employer. You would need to drop the traditional plan or switch your spouse's plan to an HDHP to remain HSA-may be able to access. Dental and vision coverage do not count as disqualifying coverage.

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

No. Medicaid is considered health coverage that disqualifies you from HSA contributions. You must drop Medicaid or lose your HDHP enrollment to contribute. Once you are no longer on Medicaid and are enrolled in an HDHP, you can resume contributions.

Do I have to contribute the full annual limit?

No. You can contribute any amount up to the limit. Many people contribute smaller amounts throughout the year via payroll deduction. There is no minimum contribution required, and you do not have to use the full limit in the year you contribute.

What if my employer and I both contribute — how do we split the limit?

The combined total of all contributions cannot exceed the annual limit. If your employer contributes $1,000, you can contribute up to $3,150 (for individual coverage in 2024). You and your employer should coordinate to avoid exceeding the limit, or you will owe a 6% excise tax on the excess.
