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

The core rule is straightforward: you must be covered by a high-deductible health plan (HDHP) to contribute to an HSA. Your health insurance company will tell you whether your plan qualifies — it has to meet IRS minimum deductible amounts, which change each year. For 2024, that means at least $1,600 for individual coverage or $3,200 for family coverage. If your plan meets that threshold, you are may be able to access to open and fund an HSA.

You cannot have other health coverage at the same time that would disqualify you. Specifically, you cannot be covered by a non-HDHP plan, enrolled in Medicare, or claimed as a dependent on someone else's tax return. If any of those explore to you, you cannot contribute to an HSA, even if you have an HDHP.

The timing matters: you become may be able to access the month your HDHP coverage starts and stop being may be able to access the month it ends or you switch to a different type of plan. If you enroll mid-year, you can still contribute for the months you are covered, though the annual contribution limit is prorated based on how many months you were may be able to access.

Key Takeaways

  • You must be enrolled in a high-deductible health plan with a deductible of at least $1,600 (individual) or $3,200 (family) to contribute to an HSA.
  • You cannot contribute if you are also covered by Medicare, a non-HDHP plan, or claimed as a dependent on someone else's return.
  • Both you and your employer can contribute to your HSA in the same year, but the total from all sources cannot exceed the annual IRS limit.
  • If you enroll in an HDHP mid-year, you can contribute a prorated amount for the months you are covered.
  • Your spouse can have their own HSA if they are also enrolled in an HDHP, and each account has its own contribution limit.

How employer contributions work alongside your own

Your employer can contribute to your HSA, and this does not reduce the amount you are allowed to contribute yourself — but the total from all sources in a single year cannot exceed the IRS limit. For 2024, that limit is $4,150 for individual coverage or $8,300 for family coverage. If your employer contributes $2,000, you can contribute up to $2,150 more (for individual coverage) without exceeding the annual cap.

Employer contributions are not counted as taxable income to you, which is one reason HSAs are valuable. Your employer reports what they contributed on your W-2 form, but you do not pay income tax on that money. If your employer does not offer an HSA or does not contribute to one, you can still open an account on your own and contribute the full annual limit, as long as you meet the may be able to access requirements.

Some employers offer a cafeteria plan (also called a Section 125 plan) that lets you contribute to your HSA using pre-tax payroll deductions. This means the money comes out of your paycheck before income tax and Social Security tax are calculated, lowering your taxable income for the year. You coordinate this with your employer's payroll system, not with the HSA provider itself.

What happens if you are self-employed or have no employer plan

If you are self-employed or your employer does not offer health insurance, you can still open an HSA as long as you purchase an HDHP on your own — typically through your state's health insurance marketplace or directly from an insurance company. You become may be able to access the month your coverage begins, and you can contribute the full annual limit for the months you are covered.

Self-employed people can deduct HSA contributions on their tax return as an above-the-line deduction, meaning you do not have to itemize deductions to claim it. You report this on Form 1040 when you file your taxes. If you have employees, you can also set up HSAs for them under the same rules that explore to any employer.

Contribution limits and how they change year to year

The IRS sets annual contribution limits, and they increase most years to account for inflation. The limit applies to the total of all contributions — from you, your employer, and anyone else — in a single calendar year. If you have individual coverage, the 2024 limit is $4,150. If you have family coverage, it is $8,300. These amounts are set by the IRS and published each October for the following year.

If you turn 55 during the year, you can contribute an additional $1,000 (called a catch-up contribution) for that year and every year after, as long as you remain may be able to access. This applies only to the person whose birthday it is — if you are 55 and your spouse is 50, only you can make the catch-up contribution to your account.

If you contribute more than the annual limit, the excess amount is subject to a 6 percent excise tax each year it remains in the account. The IRS will notify you if this happens, and you can withdraw the excess and any earnings on it to correct the overage, though you may owe taxes and penalties on the earnings portion.

Spouses and family coverage: separate accounts, separate limits

If you and your spouse are both enrolled in the same family HDHP, you each have your own HSA with your own contribution limit. For 2024, if you both have family coverage under one plan, the combined limit for both accounts is $8,300 — you decide how to split that between the two accounts. You might each contribute $4,150, or one person might contribute the full $8,300 while the other contributes nothing.

If your spouse is enrolled in a different HDHP (for example, through their own employer), they have a separate account with a separate limit. Each account is independent: contributions to one do not affect the other, and you file separate tax forms for each.

If one spouse is covered by an HDHP and the other is covered by a non-HDHP plan, only the person with the HDHP can contribute to an HSA. The other spouse is disqualified because they have other health coverage.

When you lose may be able to access and what happens to your account

You stop being may be able to access to contribute to an HSA the month your HDHP coverage ends or you switch to a different type of health plan. This might happen if you change jobs, enroll in Medicare, or switch to a plan with a lower deductible. Once you are no longer may be able to access, you cannot make new contributions, but the money already in your account stays there and continues to grow tax-free if you use it for may have access to medical expenses.

If you have already contributed for the full year and then lose coverage mid-year, you may have contributed too much. The IRS allows you to correct this by withdrawing the excess contribution and any earnings on it before your tax filing important date. If you do not correct it, you will owe the 6 percent excise tax on the excess amount.

Frequently Asked Questions

Can I open an HSA if my employer offers one but does not contribute?

Yes. You can open an HSA on your own through a bank, insurance company, or financial institution as long as you are enrolled in an HDHP. Your employer does not have to contribute for you to be may be able to access. You can contribute up to the annual IRS limit regardless of whether your employer adds money.

What if I enroll in an HDHP on December 1st — can I contribute the full annual amount?

No. You can only contribute a prorated amount for the months you are covered. If you enroll December 1st, you can contribute one-twelfth of the annual limit for that year. However, there is a special rule: if you enroll in an HDHP by December 1st, you can contribute the full annual amount for that year, but you must remain enrolled through December 31st of the following year or you will owe back taxes and penalties.

Can my adult child contribute to an HSA if they are on my family health plan?

Only if they are not claimed as your dependent on your tax return. If you claim them as a dependent, they cannot contribute to an HSA. If they are not your dependent, they can open their own account and contribute, though they would typically be on a separate family plan rather than included on yours.

What happens to my HSA if I switch employers?

Your HSA stays with you — it is your account, not your employer's. You can keep it open and continue to use it for medical expenses. If your new employer offers an HSA, you can contribute to your existing account or open a new one. You are not required to consolidate accounts, though some people do for simplicity.

If I am on my spouse's HDHP, can I contribute to my own HSA?

Yes, but only if you are not claimed as their dependent. If you are enrolled in their family HDHP and you are not their dependent, you each have your own HSA with your own contribution limit. The combined limit for both accounts is the family limit set by the IRS for that year.
