A health savings account (HSA) is worth it mainly for people who are enrolled in a high-deductible health plan (HDHP) and can afford to put cash into the account. The main purpose of an HSA is to pay medical costs with untaxed money. Contributions lower your taxable income, the balance can be invested and grow without tax, and withdrawals for qualified medical expenses are tax-free. The account belongs to you, and the money never expires. The drawbacks are the requirement to carry a high-deductible plan, the cash it takes to fund the account, and tax penalties if you use the money for anything other than medical care before age 65. If you expect heavy medical bills or cannot spare money for contributions, a lower-deductible plan without an HSA may cost you less.

Advantages of an HSA

The tax treatment is unusually generous

The HSA’s main benefit is that it can avoid tax at three points.

1. Going in. Contributions made through payroll come out of your paycheck before income tax. If you contribute on your own with after-tax money, you can deduct the contribution on your federal return. Payroll contributions made through an employer’s cafeteria plan also generally avoid Social Security and Medicare taxes, which a deduction on your return does not recover.
2. While invested. Interest, dividends and gains inside the account are not taxed as they build.
3. Coming out. Distributions used for qualified medical expenses are tax-free.

Most other accounts give you one or two of these breaks. A traditional 401(k) or IRA lets you contribute before tax, but withdrawals are taxed. A Roth IRA gives tax-free withdrawals, but contributions are made with taxed money. When the HSA is used for medical costs, it gets both breaks.

It covers a wide range of medical costs

You can use HSA money for deductibles, copays, coinsurance and many costs your health plan does not cover. Qualified expenses include:

• Dental care
• Vision care
• Prescription drugs
• Over-the-counter health products
• Menstrual care products
• Family planning costs, such as contraception and fertility treatment

HSA money generally cannot pay health insurance premiums, but there are exceptions: COBRA premiums after a job loss, health coverage premiums while you are receiving unemployment compensation, and, at 65 or older, Medicare premiums (but not Medicare supplement policies such as Medigap).

Many HSA providers issue an HSA card. This is a debit card linked to the account that you can use at a pharmacy or doctor’s office, so you don’t have to pay out of pocket and file for reimbursement later.

The account is yours, and the money doesn’t expire

An HSA isn’t tied to your employer. If you leave your job, the account and all the money in it stay with you. You can keep contributing as long as you have HSA-eligible coverage, whether it comes from a new employer or a plan you buy yourself.

Unused HSA money rolls over every year, with no limit. You also don’t have to reimburse yourself in the same year you have an expense. If you paid a qualified bill out of pocket after the HSA was opened and you kept the receipt, you can take a tax-free withdrawal for it years later. Some account holders pay current bills with other money, let the HSA grow, and keep receipts so they can pull money out tax-free whenever they need it.

It can serve as a retirement account

Most HSA providers let you invest the balance beyond a cash cushion in stocks, bonds, mutual funds or ETFs, as you would in an IRA. You can keep the account invested even after you switch to a health plan that isn’t a high-deductible plan. You can no longer contribute, but the existing money keeps its tax benefits.

At 65, the account becomes more flexible: non-medical withdrawals no longer carry the 20% additional tax and are taxed as income, like traditional IRA withdrawals, while medical withdrawals stay tax-free. Health care is a major retirement expense: one large retirement-plan provider estimated that a 65-year-old retiring in 2025 would spend an average of $172,500 on health care and medical costs during retirement. Money saved for those costs in an HSA can be spent without tax.

Disadvantages of an HSA

You must have a high-deductible plan

The deductible is the amount you pay for covered care each year before your insurer begins to pay. To qualify as an HDHP in 2026, a plan must have a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. Many plans set their deductible well above those minimums.

HDHPs generally have lower premiums than other plans. If you rarely see a doctor, the premium savings plus the HSA tax breaks can cost less than a plan with a low deductible. If you have frequent or predictable medical needs, a plan with a lower deductible may cost less overall because the insurer starts paying sooner. Some people prefer that the insurer, not their own savings, pay large bills, even if it means higher monthly premiums.

Eligibility also involves more than the plan itself. While you are contributing, you generally can’t have other health coverage that is not an HDHP (including a general-purpose FSA through a spouse), can’t be enrolled in Medicare, and can’t be claimed as a dependent on someone else’s tax return.

The value depends on the cash you put in

The tax benefits apply only to money you actually contribute. For 2026, the limit is $4,400 for self-only coverage and $8,750 for family coverage, and anyone 55 or older can add a $1,000 catch-up contribution. Employer contributions count toward the same limit.

Contributing the maximum means less money for living expenses, paying down debt, an emergency fund or other investments. The account builds over time only if your contributions exceed your medical spending. A serious illness or emergency early on can empty the account while you still owe the rest of a high deductible.

Non-medical withdrawals are taxed and penalized

Money withdrawn for anything other than a qualified medical expense is taxed as income and, in most cases, an additional 20% tax applies. Distributions are reported on your tax return. There is no exception to the income tax on non-medical withdrawals. The 20% additional tax doesn’t apply if the withdrawal is made after you turn 65, after you become disabled, or after your death (taken by your estate or beneficiary).

These rules are stricter than those for some workplace retirement plans. Many 401(k) and 403(b) plans allow hardship withdrawals, which are taxed but may avoid the early-withdrawal penalty in certain situations. Under 65, an HSA used for a non-medical emergency usually triggers both income tax and the 20% additional tax.

Other limits that can change the answer

• Medicare stops contributions. Once you enroll in any part of Medicare, you can no longer contribute, though you can still spend the existing money. People who work past 65 and delay Medicare can keep contributing if they remain on a qualifying HDHP.
• State taxes may differ. A few states, including California and New Jersey, don’t follow the federal HSA tax treatment, so contributions or earnings may be taxed at the state level.
• Who inherits matters. A spouse named as beneficiary can treat the account as their own HSA. For other beneficiaries, the account ends and the balance generally becomes taxable income to them.
• Fees and investment choices vary by provider. Some HSAs charge account fees or offer only a small selection of investments, which reduces the gains.

Example: HSA plan vs. a plan without an HSA

As a hypothetical illustration, not quotes for any plan, suppose an individual earns $70,000 and contributes $5,000 to an HSA through payroll. Assume a 22% federal marginal income tax rate and the 7.65% employee share of Social Security and Medicare tax, with no state income tax.

• Federal income tax saved: $5,000 × 22% = $1,100
• Payroll tax saved: $5,000 × 7.65% = $382.50
• Total first-year tax saved: $1,482.50

Compare two plans. Plan A is an HDHP with lower premiums. Plan B has a low deductible and premiums that are $1,200 a year higher. If this person has only routine care, Plan A comes out ahead by the $1,200 in premiums plus the $1,482.50 in tax savings, and whatever is left in the HSA rolls over. If they have a large bill and reach Plan A’s deductible, they pay more out of pocket in Plan A than in Plan B. The question is whether the premium difference plus the tax savings covers that gap.

HSA vs. FSA and HRA

If an HSA isn’t available or doesn’t suit you, an employer may offer one of two related accounts.

A flexible spending account (FSA) is also funded with pre-tax money, and qualified withdrawals are tax-free. It differs from an HSA in two ways:

1. You can have an FSA with any type of health plan, not only an HDHP.
2. Unused money is forfeited at the end of the year unless your plan allows a carryover or a grace period, and not all plans do. The IRS limits carryovers; for example, the maximum carryover from 2025 to 2026 was $680.

A health reimbursement arrangement (HRA) is funded only by your employer. Employer contributions are not counted as your income, and the law sets no general cap on how much an employer can put in. The money can be used only for qualified medical expenses. Balances can roll over, but the plan may limit how much you can be reimbursed in a coverage period.

FSAs and HRAs are tied to your employer, and you may lose the money when you leave the job. Neither can be invested like an HSA. They cover largely the same expenses, but some items an HSA can pay for, such as certain insurance premiums, may not be covered.

Who should get an HSA?

An HSA is likely a good fit if:

• You are healthy, expect few medical costs, and would choose a lower-premium HDHP anyway.
• You can contribute regularly without needing the money for living expenses or high-interest debt.
• You already contribute the maximum to a 401(k) or IRA and want another tax-advantaged account.
• Your employer contributes to the HSA, which is money you don’t have to put in yourself.
• You can keep receipts and can leave the account invested for years.

It may not be a good fit if:

• You have ongoing, high medical costs and would reach a high deductible every year.
• Your cash is tight and a large unexpected bill would be hard to cover until the HSA balance grows.
• You might need to withdraw for non-medical reasons before 65.
• You are already enrolled in Medicare, which makes you ineligible to contribute.

How to get the most from an HSA

Contribute up to the limit if you can afford it, ideally through payroll. Keep enough in cash to cover your deductible, and invest the rest based on your time horizon and how much risk you are comfortable with. Broad index funds have lower risk than individual stocks but still fluctuate.

FAQs

The Bottom Line

An HSA suits people who are generally healthy, choose a high-deductible plan, and can contribute without straining their budget. For them, the tax savings, rollover and investment options can turn the account into a long-term fund for medical costs, including in retirement. People with heavy recurring medical bills, tight cash, or a likely need for non-medical withdrawals before 65 may pay less overall with a lower-deductible plan.
