What a healthcare savings account is and who can open one

A healthcare savings account is a tax-advantaged account you own and control that holds money specifically for medical expenses. The three main types are a Health Savings Account (HSA), a Flexible Spending Account (FSA), and a Dependent Care FSA. Each has different rules about who can open one, how much you can put in, and what you can spend the money on.

An HSA requires you to be enrolled in a high-deductible health plan (HDHP) through your employer, the marketplace, or a private insurer. You can open one on your own if you have individual coverage, or your employer can set one up for you. An FSA is almost always offered through your employer's benefits package—you cannot open one independently. A Dependent Care FSA is also employer-based and covers childcare or adult dependent care expenses only.

The account belongs to you, not your employer, even if they help you set it up. You decide how much to contribute each year (within legal limits), and you keep any unused balance, depending on the account type.

Key Takeaways

  • HSAs require enrollment in a high-deductible health plan and let you carry unused money forward year to year, while FSAs typically require you to spend the money within the calendar year or lose it.
  • Employer-based accounts (FSA and Dependent Care FSA) are set up during your company's open enrollment period, usually once per year in the fall.
  • Individual HSAs can be opened at any time through a bank, credit union, or insurance company, and you can start contributing immediately.
  • Contribution limits are set by federal law and change each year; for 2024, individual HSA limits are $4,150 and family HSA limits are $8,300.
  • You will need your Social Security number, proof of health plan enrollment, and banking information to open an account.

Opening an HSA through your employer

If your employer offers an HSA, they typically present it during open enrollment, the annual window when you can change your health plan and benefits. This is usually in the fall, though some employers hold it at other times. Your employer will provide a list of HSA providers they work with—often banks, credit unions, or insurance companies.

You choose one provider from that list and complete an enrollment form. The form asks for your name, Social Security number, date of birth, and confirmation that you are enrolled in an HDHP. Your employer sends the form to the provider on your behalf. The provider then opens the account and sends you login credentials, usually within one to two weeks.

Once the account is open, you authorize how much of your paycheck to contribute each pay period. Your employer deducts that amount before taxes are calculated, which reduces your taxable income for the year. The money goes directly into your HSA account.

Opening an individual HSA outside of an employer plan

You can open an HSA on your own at any time if you have individual health insurance through the marketplace or a private plan, as long as it qualifies as a high-deductible plan. You do not have to wait for an enrollment period.

Search for HSA providers in your state—common ones include Fidelity, HealthEquity, Lively, and local banks or credit unions. Visit the provider's website and look for "open an HSA" or "new account." You will need your Social Security number, proof of HDHP enrollment (your insurance card or a letter from your insurer showing your plan type), and a bank account for transfers.

The application takes 10 to 15 minutes online. The provider verifies your HDHP status with your insurer, which usually takes one to three business days. Once approved, you can log in and make contributions immediately. You can set up automatic monthly transfers from your bank account, or make lump-sum contributions.

Setting up an FSA through your employer

An FSA is only available through your employer's benefits plan. During open enrollment, your HR or benefits department will present FSA options—usually a healthcare FSA, a Dependent Care FSA, or both. You choose the account type and decide how much to contribute for the coming year.

Complete the enrollment form provided by your employer or their benefits administrator. The form asks for your name, Social Security number, and the annual contribution amount. Unlike an HSA, you do not choose an external provider; your employer or a third-party administrator they hire manages the account.

Your contributions are deducted from your paycheck before taxes, reducing your taxable income. The money is available to spend immediately once the plan year begins, usually January 1. You receive a debit card or reimbursement instructions so you can access the funds when you pay for medical expenses.

Understanding contribution limits and deadlines

Federal law sets annual contribution limits for HSAs and FSAs, and these limits change each year. For 2024, you can contribute up to $4,150 to an individual HSA or $8,300 to a family HSA. For FSAs, the limit is $3,300 per person per year. Dependent Care FSAs have a separate limit of $5,000 per household per year.

For employer-based accounts, you must choose your contribution amount during open enrollment. If you miss the window, you cannot change your contribution until the next open enrollment period, unless you have a may have access to life event—marriage, birth of a child, loss of other health coverage, or a significant change in income.

For individual HSAs, you can contribute at any time during the year. You have until the tax filing deadline (usually April 15 of the following year) to make contributions for the previous year. If you open an HSA mid-year, you can still contribute the full annual amount for that year, as long as you were may be able to access for the entire year.

What documents you need to have ready

Before you start the account opening process, gather these documents: your Social Security number, proof of health plan enrollment (your insurance card or a letter from your insurer showing your plan type and deductible), and information about a bank account where you want transfers to go.

For employer-based accounts, your employer or benefits administrator handles most of the verification. For individual HSAs, the provider will contact your insurer to confirm your HDHP status, so make sure the name and date of birth on your application match your insurance records exactly.

If you are opening an FSA or Dependent Care FSA, you may also need to provide documentation of dependent care expenses or a dependent's Social Security number, depending on your employer's plan rules.

How to fund your account after it opens

For employer-based accounts, funding happens automatically through payroll deduction. You authorize the amount during enrollment, and your employer deducts it from each paycheck. The money appears in your account within one to three business days of each payroll cycle.

For individual HSAs, you can set up automatic monthly transfers from your bank account, make a one-time lump-sum transfer, or deposit a check if the provider accepts them. Most providers let you link your bank account online and authorize transfers immediately. Some also let you transfer money from another HSA if you are switching providers.

You can contribute to an HSA at any time during the year, but contributions for a specific tax year must be made by the tax filing deadline. For an FSA, contributions are set at the start of the plan year and cannot be changed unless you have a may have access to life event.

Frequently Asked Questions

Can I have both an HSA and an FSA at the same time?

No. If you have an HSA, you cannot also have a healthcare FSA. However, you can have an HSA and a Dependent Care FSA at the same time, since they cover different types of expenses. If your employer offers both, you must choose one or the other for healthcare expenses.

What happens to money I do not spend in my FSA by the end of the year?

Most FSAs have a "use it or lose it" rule—unused money does not carry over to the next year. However, some employers offer a grace period (usually two and a half months into the next year) or a carryover of up to $640. Check your plan documents to see which rule applies to your account. HSAs are different; unused money rolls over indefinitely.

Can I withdraw money from my HSA for non-medical expenses?

Yes, but you will owe income tax on the withdrawal plus a 20 percent penalty if you are under age 65. After age 65, you can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals. Money spent on may have access to medical expenses comes out tax-free at any age.

What if I change jobs or lose my health insurance?

Your HSA stays with you—it is not tied to your employer or your insurance plan. You keep the account and the money in it. If you lose HDHP coverage, you can no longer make new contributions, but you can still spend existing money on medical expenses. If you get a new job with an HDHP, you can resume contributions to the same account or open a new one.

How do I prove that an expense is medical and may be able to access for reimbursement?

Keep receipts and invoices for all expenses you pay from your account. The IRS defines may have access to medical expenses as costs for diagnosis, treatment, or prevention of disease, including insurance premiums, copays, deductibles, and prescription drugs. Your provider may ask for documentation if you request a reimbursement or if they audit your account.
