You can open an HSA if you have a high-deductible health plan and meet income limits set by the IRS

To open a health savings account, you need three things: enrollment in a high-deductible health plan (HDHP), no other health coverage that disqualifies you, and income below the IRS limit for your filing status. The income limits change yearly—for 2024, single filers cannot earn more than $194,500 and married filers cannot earn more than $388,900. You do not need to be employed; self-employed people and those on Medicare can open HSAs under specific conditions.

The HDHP is the real gatekeeper. Your plan must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage in 2024, and your out-of-pocket maximum cannot exceed $8,050 for individual or $16,100 for family. If your current plan does not meet these thresholds, you cannot open an HSA until you switch to one that does.

You can open an HSA through your employer's plan administrator, a bank, a credit union, or a brokerage firm. Many employers offer HSAs as part of their benefits package and may even contribute money to your account as part of compensation. If you buy your own HDHP through the health insurance marketplace or directly from an insurer, you can open an HSA independently at any financial institution that offers them.

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 open an HSA.
  • Your income cannot exceed $194,500 if you file taxes as a single person, or $388,900 if you file as married filing jointly, though these limits change each year.
  • You cannot have other health coverage like Medicare, Medicaid, or a spouse's low-deductible plan at the same time you contribute to an HSA.
  • You can open an HSA through your employer, a bank, credit union, or brokerage—whichever offers the features and fees that work for your situation.

What disqualifies you from opening an HSA

Having other health coverage is the most common reason people cannot open an HSA. If you are enrolled in Medicare, covered by Medicaid, or covered under your spouse's low-deductible health plan, you cannot contribute to an HSA. The IRS treats these as disqualifying coverage even if you also have an HDHP. The only exception is if your spouse has an HDHP and you both open separate HSAs—but you cannot be on their plan.

Being claimed as a dependent on someone else's tax return also blocks you from opening an HSA. If your parents claim you as a dependent, you cannot open an account until that changes, even if you have your own HDHP and income.

Exceeding the income limit for your filing status disqualifies you for that tax year. If your income crosses the threshold partway through the year, you can still open and contribute to an HSA, but you may owe a penalty when you file taxes. The IRS calls this an excess contribution, and you will need to withdraw the overage plus any earnings it generated.

How to open an HSA through your employer

If your employer offers an HDHP with an HSA option, the process usually starts with your benefits enrollment period. Your employer's benefits administrator or HR department will provide enrollment materials that explain the HDHP and the HSA account options available. You choose the HSA provider (often your employer has already selected one), complete the account setup form, and elect how much to contribute from each paycheck.

Your employer may contribute to your HSA as part of your compensation package. This is separate from your own contributions and does not count against your annual contribution limit—it is an addition to it. Some employers contribute a flat amount; others match a percentage of what you contribute. Check your benefits summary to see what your employer offers.

Once enrolled, your contributions are deducted from your paycheck before taxes are calculated, which lowers your taxable income for the year. Your HSA provider will send you a debit card, checkbook, or online portal to spend the money on may have access to medical expenses. You do not have to spend it in the year you contribute—unused money rolls over and grows tax-free indefinitely.

Opening an HSA on your own if you buy your own health plan

If you purchase an HDHP directly from an insurer or through the health insurance marketplace, you can open an HSA at any bank, credit union, or brokerage that offers them. Search for "HSA providers" or check your insurer's website—many insurers partner with specific HSA administrators and may recommend them, though you are not required to use their recommendation.

Compare providers on three things: monthly fees (some charge $0, others charge $2 to $5 per month), investment options if you plan to invest HSA money rather than spend it immediately, and whether they offer a debit card or require you to submit receipts for reimbursement. A provider with no monthly fee and a debit card is usually the simplest choice if you plan to use the money regularly.

When you open the account, you will provide your Social Security number, proof of HDHP enrollment (your insurance card or a letter from your insurer), and banking information if you want to fund it by transfer. You can contribute as a lump sum or set up automatic monthly transfers. Unlike employer plans, your contributions are not deducted from your paycheck, so you will need to deduct them yourself when you file taxes using IRS Form 8889.

Self-employed people and HSA may be able to access

If you are self-employed, you can open an HSA as long as you have an HDHP and meet the income limit. You purchase your HDHP directly from an insurer or the marketplace, then open an HSA at a bank or brokerage. The process is identical to buying your own plan as an employee.

Self-employed people can deduct HSA contributions on their tax return, but the deduction works differently than for employees. You report it on Form 1040 as an adjustment to income, not as a business expense. Your accountant or tax software can walk you through this, or you can refer to IRS Publication 969 for the exact rules.

Special situations: Medicare, Medicaid, and dependent status

If you are on Medicare, you cannot contribute to an HSA, even if you also have an HDHP. Once you enroll in Medicare Part A or Part B, your HSA contributions stop. If you already have an HSA, you can keep it and spend the money on may have access to medical expenses, but you cannot add new money to it.

Medicaid coverage also blocks HSA contributions. Some states have programs that combine Medicaid with an HDHP, but these do not allow HSA contributions. Check with your state Medicaid office if you are unsure whether your coverage qualifies.

If you are claimed as a dependent on your parents' tax return, you cannot open an HSA until you file your own return independently. This applies even if you have your own income and your own HDHP. Once you stop being claimed as a dependent, you can open an account in the next tax year.

What happens after you open your HSA

After your account is open, you receive a tax identification number for the account and documentation showing your contribution limit for the year. The IRS sets annual contribution limits—for 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. If your employer contributes, that counts toward your limit, so you cannot contribute an additional $4,150 on top of what they give you.

You can spend HSA money on may have access to medical expenses immediately—copays, deductibles, prescriptions, dental work, vision care, and many other health costs. Keep receipts for everything you buy with HSA money. If you are audited, the IRS may ask for proof that expenses were may have access to. Spending HSA money on non-may have access to expenses triggers a 20% penalty plus income tax on the amount withdrawn.

Money you do not spend stays in the account and grows tax-free. After age 65, you can withdraw money for any reason without penalty, though non-medical withdrawals are taxed as income. This makes an HSA a powerful retirement savings tool if you can afford to let the money accumulate.

Frequently Asked Questions

Can I open an HSA if I am married but my spouse is not on my health plan?

What if I lose my HDHP coverage partway through the year?

You can no longer contribute to your HSA once you switch to a different health plan. Money already in the account stays there and can still be spent on may have access to medical expenses. If you switch back to an HDHP later, you can resume contributions.

Do I have to use my employer's HSA provider, or can I open my own?

You can open your own HSA at any provider, even if your employer offers one. Some people do this to avoid fees or to access better investment options. Just make sure your total contributions across all accounts do not exceed the annual limit.

Can I open an HSA if I am self-employed and have no employees?

Yes. You purchase an HDHP as a self-employed person and open an HSA at any bank or brokerage. You deduct contributions on your tax return as an adjustment to income, and the money grows tax-free like any other HSA.

What if my income goes over the limit after I have already opened an HSA?

You will owe a penalty on contributions made after your income exceeded the limit. The IRS requires you to withdraw the excess and any earnings it generated. Report this on Form 8889 when you file taxes, and you will owe income tax plus a 6% penalty on the excess amount.
