What a healthcare savings account does and who can open one
A healthcare savings account lets you set aside money before taxes are taken out, then spend it on medical costs without paying income tax on that money. The three 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 it on.
To open any of these accounts, you must be enrolled in a specific type of health insurance plan, or in the case of dependent care, have a may have access to dependent and a workplace plan. You cannot open one on your own—they are offered through your employer, your spouse's employer, or in rare cases through a professional association or union. The account itself is managed by a third-party administrator that your employer contracts with, not by a bank.
The main reason to set one up is the tax savings. If you put $3,000 into an HSA this year and spend it on deductibles, copays, prescriptions, or dental work, you avoid paying federal income tax, Social Security tax, and Medicare tax on that $3,000. State income tax is also avoided in most states. That can save you 20 to 40 percent of the amount you contribute, depending on your tax bracket.
Key Takeaways
- You can only open an HSA if you are enrolled in a high-deductible health plan (HDHP), and you cannot have other health coverage at the same time.
- FSAs are offered by many employers and do not require a specific health plan, but money left unspent at the end of the year is forfeited.
- HSAs let you roll over unused money year to year and withdraw it tax-free after age 65 for any reason, making them a long-term savings tool.
- You enroll during your employer's open enrollment period or within 30 to 60 days of a may have access to life event like a job change or birth.
- Once enrolled, you receive a debit card or reimbursement instructions and can begin spending on may be able to access medical, dental, vision, and pharmacy costs when ready.
Health Savings Accounts (HSAs): may be able to access and enrollment
An HSA is available only if you are enrolled in a high-deductible health plan (HDHP). In 2024, an HDHP has a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your employer's benefits team can tell you whether any of the plans offered meet this definition. You cannot have any other health coverage—no spouse's plan, no Medicare, no Medicaid, no military coverage—at the same time you hold an HSA.
If you meet these conditions, you can open an HSA during your employer's open enrollment period, which is usually once a year in the fall or winter. If you miss that window, you have 30 to 60 days after a may have access to life event—a job change, loss of other coverage, marriage, birth, or adoption—to enroll. Your employer's HR or benefits department will tell you the exact important date for your situation.
To enroll, you fill out a form provided by your employer or the plan administrator. The form asks for your name, Social Security number, date of birth, and confirmation that you meet the may be able to access rules. You choose how much to contribute for the year, up to the annual limit set by the IRS (for 2024, $4,150 for individual coverage or $8,300 for family coverage). Your employer may also contribute to your account; that contribution counts toward your limit but does not reduce the tax benefit.
Flexible Spending Accounts (FSAs): how they differ from HSAs
An FSA is a workplace benefit that does not require a specific health plan. Your employer straightforward needs to offer one. You can have an FSA even if you are on a low-deductible plan, on Medicare, or covered by Medicaid. The main trade-off is that FSAs do not roll over—money you do not spend by December 31 is forfeited, with limited exceptions.
Most employers allow you to carry over up to $640 into the next year (this amount changes annually), or you can choose a grace period of up to 2.5 months into the following year to spend down your balance. If you do neither, the unused money goes back to your employer. This makes FSAs riskier if you are unsure how much medical spending you will have.
Enrollment works the same way as an HSA: during open enrollment or within 30 to 60 days of a life event. You choose an annual contribution amount, which for 2024 has a limit of $3,200. Your employer deducts that amount from your paycheck in equal installments throughout the year, and you can begin spending when ready, even if you have not yet contributed the full amount.
Dependent Care FSAs for childcare and elder care costs
A Dependent Care FSA is separate from a healthcare FSA and covers childcare, preschool, after-school programs, and adult day care for aging parents or disabled family members. You do not need a specific health plan to open one. You must have a may have access to dependent and a workplace plan that offers this benefit.
The annual limit for 2024 is $5,000 per household. Like a healthcare FSA, unused money is forfeited at year-end, though the same carryover and grace period rules explore. Enrollment happens during the same open enrollment window as other benefits. You will need to provide the name, date of birth, and tax ID of the dependent you are claiming, and the name and tax ID of the care provider.
The enrollment process and timeline
Enrollment begins when your employer opens its benefits window, usually in October or November for coverage starting January 1. Your HR or benefits team will send you a link to an online portal, a paper form, or both. You log in or fill out the form, select which accounts to open, and enter your contribution amount.
Once you submit, the plan administrator (not your employer) processes your enrollment. This typically takes one to two weeks. You will receive a confirmation email with your account number, the name of the administrator, and instructions for accessing your account online or by phone. Some administrators mail a debit card; others require you to submit receipts for reimbursement.
Your contributions begin on the effective date, usually January 1 if you enrolled during the fall window. Money is deducted from your paycheck before taxes are calculated, so you see the tax savings when ready in your take-home pay. You can begin spending on may be able to access costs right away, even if your full annual contribution has not yet been deducted.
How to use your account once it is open
Once enrolled, you receive instructions on how to spend your money. Most HSAs and FSAs issue a debit card that works like a regular card at pharmacies, doctors' offices, and other providers. Some accounts require you to pay out of pocket and then submit a receipt to the administrator for reimbursement. A few use both methods.
may be able to access expenses include deductibles, copays, coinsurance, prescription medications, dental work, vision care, hearing aids, and medical equipment like crutches or blood pressure monitors. Cosmetic procedures, gym memberships, and over-the-counter medications (unless prescribed by a doctor) are not may be able to access. The IRS publishes a full list on its website, and your plan administrator can answer specific questions.
Keep receipts and explanations of benefits (EOBs) from your insurance company. If the IRS audits your account, you may need to prove that expenses were may be able to access. Many administrators have online portals where you can upload receipts and track your balance in real time.
What happens to unused money and account rules after enrollment
HSAs are the most flexible. You can carry over unused money indefinitely, and after age 65 you can withdraw it for any reason without penalty (though you will owe income tax on non-medical withdrawals). This makes an HSA a retirement savings tool if you do not spend all your contributions each year. Some people use HSAs this way intentionally, letting the balance grow for decades.
FSAs and Dependent Care FSAs are use-it-or-lose-it. Money not spent by December 31 (or by the end of the grace period if your employer offers one) is forfeited. This is why many people contribute conservatively to FSAs—only the amount they are confident they will spend. If you have a major medical event mid-year, you can request a mid-year change to increase your FSA contribution, but most employers allow this only for specific life events, not for unexpected medical costs.
If you leave your job, you can take your HSA with you—it is your property. FSA and Dependent Care FSA balances stay with your employer; you cannot transfer them. Some employers allow you to continue spending from an FSA for a limited time after you leave (called COBRA continuation), but this is not may provide.
Common mistakes to avoid when setting up
The biggest mistake with FSAs is overestimating how much you will spend and losing money at year-end. If you are unsure, start low and increase next year if you find you have leftover funds. With HSAs, the opposite mistake is underestimating—many people contribute too little and miss out on tax savings.
Another common error is not understanding which expenses are may be able to access. Vitamins, supplements, and over-the-counter pain relievers are not may be able to access unless a doctor prescribes them. Dental and vision care are may be able to access, but only if they are not covered by a separate dental or vision plan—check your plan documents first.
A third mistake is not updating your account if your life changes. If you lose HSA may be able to access (for example, by enrolling in Medicare or another health plan), you must stop contributing when ready. Continuing to contribute after you are no longer may be able to access can trigger penalties and taxes. Your HR team should notify you of changes, but it is your responsibility to confirm.
