A Health Savings Account is a tax-advantaged savings account tied to a high-deductible health plan

A Health Savings Account (HSA) is a bank account you own that holds money specifically for medical expenses. The account itself is not the insurance — it works alongside a high-deductible health plan (HDHP). Money you put into an HSA reduces your taxable income, grows tax-free, and withdrawals for may have access to medical costs are never taxed. You keep the account even if you change jobs or health plans, and any money you don't spend stays in the account to use later.

The main trade-off is that your health insurance must have a higher deductible than a standard plan — meaning you pay more out of pocket before insurance kicks in. In exchange, you get the tax advantages and the ability to save for future medical costs. The account is yours to manage; no employer or insurance company controls how you spend it, as long as the expense qualifies.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open and contribute to an HSA; standard health plans do not may have access to.
  • Money you contribute reduces your taxable income, and withdrawals for medical expenses are never taxed, making HSAs a tax shelter for healthcare costs.
  • You can use HSA funds for deductibles, copays, prescriptions, dental work, vision care, and many other medical services, but not for insurance premiums or cosmetic procedures.
  • The account belongs to you permanently — you keep it even if you leave your job, change insurance, or retire, and unused money rolls forward year to year.
  • After age 65, you can withdraw money for any reason without penalty, though non-medical withdrawals are taxed as income.

Who can open an HSA and when

You must meet three conditions to open an HSA. First, you must be enrolled in a high-deductible health plan — either through an employer, the individual market, or Medicare Advantage (in some cases). Second, you cannot be covered by any other health insurance that is not an HDHP, with limited exceptions for accident, disability, dental, vision, and long-term care coverage. Third, you cannot be claimed as a dependent on someone else's tax return, and you cannot be enrolled in Medicare (with the exception of certain Medicare Advantage plans).

You can open an HSA at any time during the year, but contributions for a given tax year must be made by the tax filing deadline (usually April 15 of the following year). If you enroll in an HDHP mid-year, you can still contribute to an HSA for that year, though the amount is prorated based on the number of months you were covered. Some employers offer HSAs through payroll, which makes contributions automatic; others require you to open an account at a bank or financial institution on your own.

Contribution limits and how much you can put in

The IRS sets annual contribution limits that change each year. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These limits apply to all your HSA accounts combined — if you have multiple accounts, the total across all of them cannot exceed the limit. If you are age 55 or older, you can contribute an additional $1,000 per year (called a catch-up contribution). Contributions can come from you, your employer, or both, but the total cannot exceed the annual limit.

If you enroll in an HDHP partway through the year, your contribution limit is reduced proportionally. For example, if you enroll in July, you can contribute only 7/12 of the annual limit. The one exception is the "last-month rule": if you enroll in December, you can contribute the full annual amount for that year, but you must remain enrolled in an HDHP through the following March or you will owe taxes and penalties on the excess.

What medical expenses you can pay for with HSA funds

HSA funds can cover a broad range of medical, dental, and vision expenses. may have access to expenses include deductibles, copays, and coinsurance on your health plan; prescription medications; dental work like cleanings, fillings, and orthodontia; vision care including eye exams, glasses, and contact lenses; hearing aids and related care; mental health counseling; physical therapy; and many over-the-counter items like pain relievers, allergy medicine, and first-aid supplies. You can also use HSA funds to pay for medical equipment like blood pressure monitors, thermometers, and glucose meters.

Expenses that do not may have access to include health insurance premiums (with narrow exceptions for COBRA, Medicare, and long-term care insurance), cosmetic procedures, gym memberships, and general wellness products. If you are unsure whether a specific expense qualifies, the IRS publishes a detailed list, and your HSA provider can usually answer questions about particular items. Keeping receipts is important — while you do not need to submit them when you withdraw money, the IRS can ask for proof if your account is audited.

How HSA funds grow and what happens to unused money

Money in an HSA can be invested in the same way as a retirement account — through mutual funds, stocks, bonds, or money market accounts, depending on what your HSA provider offers. Any earnings on those investments are tax-free. Unlike a Flexible Spending Account (FSA), which requires you to spend the money each year or lose it, HSA funds roll over indefinitely. Money you do not spend in one year stays in the account and is available to use in future years, making it a long-term savings tool for healthcare costs.

This rollover feature means an HSA can function as a retirement account for medical expenses. Many people use HSAs to save for healthcare costs in retirement, when medical expenses typically increase. After age 65, you can withdraw money from an HSA for any reason without penalty, though non-medical withdrawals are taxed as ordinary income — similar to withdrawals from a traditional IRA.

The relationship between your HSA and your health plan deductible

An HSA is designed to help you pay your health plan's deductible and other out-of-pocket costs. Your deductible is the amount you must pay for medical services before your insurance starts to pay. With a high-deductible plan, this amount is typically $1,500 to $3,000 for individual coverage or $3,000 to $6,000 for family coverage (these ranges vary by year and plan). The HSA gives you a tax-advantaged way to set aside money to cover that deductible.

Once you meet your deductible, your insurance begins to pay its share of costs, but you may still owe copays or coinsurance. HSA funds can cover those costs too. The HSA is separate from the insurance plan itself — your insurance company does not control the HSA, and you do not have to use HSA funds to pay your deductible. You can pay the deductible out of pocket and save your HSA funds for future years if you prefer, though most people use the HSA to cover current medical expenses.

Withdrawals, taxes, and penalties for non-medical use

You can withdraw money from your HSA at any time for any reason, but only withdrawals for may have access to medical expenses are tax-free. If you withdraw money for a non-medical expense before age 65, you owe income tax on the withdrawal plus a 20% penalty. For example, if you withdraw $1,000 for a non-medical expense and you are in the 22% tax bracket, you would owe $220 in taxes plus $200 in penalties, for a total of $420. After age 65, the 20% penalty goes away, but you still owe income tax on non-medical withdrawals.

Withdrawals for medical expenses are never taxed or penalized, regardless of your age. You do not need to submit receipts to your HSA provider when you withdraw money, but you should keep receipts in case the IRS audits your account. If you cannot prove that a withdrawal was for a may have access to medical expense, the IRS may assess taxes and penalties retroactively. Some HSA providers offer debit cards that can be used directly at pharmacies and medical providers, which creates an automatic record of the transaction.
