Health savings accounts offer one of the most generous tax benefits available to American savers. Here is how they work, who qualifies and how to use one to cover medical costs today and in retirement.
What Makes an HSA Special
A health savings account, or HSA, is a tax-advantaged account for medical expenses. It is often described as having a triple tax advantage, because money can go in, grow and come out without federal income tax when used correctly.
First, contributions are tax-deductible or made with pre-tax dollars through payroll. That lowers your taxable income for the year, which reduces your tax bill in the same way a traditional retirement contribution does.
Second, the money in the account can grow tax-free. Many HSA providers allow you to invest your balance in mutual funds or other investments once it reaches a certain level, and you owe no tax on the gains.
Third, withdrawals for qualified medical expenses are tax-free. Doctor visits, prescriptions, dental care, vision care and many other health costs can be paid directly from the account without any tax.
Payroll contributions offer an additional benefit. When you contribute through your employer, contributions generally avoid Social Security and Medicare taxes as well, making the savings even larger.
These advantages add up quickly. Someone in a moderate tax bracket who contributes through payroll can save a meaningful share of every dollar deposited, and that money can then grow for years without being reduced by taxes on dividends or gains.
Who Is Eligible
To contribute to an HSA, you must be enrolled in a qualifying high-deductible health plan. These plans have higher deductibles than traditional plans, which means you pay more out of pocket before insurance coverage begins.
You generally cannot have other health coverage that disqualifies you, such as a non-high-deductible plan through a spouse. You also cannot contribute once you are enrolled in Medicare or if someone else can claim you as a dependent.
The IRS sets annual contribution limits for individuals and families, and the limits adjust over time. People age 55 and older can make an additional catch-up contribution each year.
Employers sometimes contribute to employees’ HSAs. Employer contributions count toward the annual limit, but they are essentially free money that strengthens your health savings.
Before choosing a high-deductible plan, compare total costs. Lower premiums and HSA tax savings can make these plans attractive, but you need enough cash flow or savings to handle the higher deductible.
HSAs Versus Flexible Spending Accounts
HSAs are often confused with flexible spending accounts, or FSAs. Both let you pay medical costs with pre-tax money, but they work very differently over time.
HSA money rolls over from year to year with no deadline. Unused FSA money, by contrast, is often forfeited at the end of the plan year, although some plans allow a limited carryover or grace period.
HSAs belong to you, not your employer. If you change jobs or retire, the account and its balance stay with you, while FSAs are typically tied to your current employer.
FSAs do not require a high-deductible health plan, which makes them available to more people. However, they lack the investment options and long-term growth potential that make HSAs so powerful.
Some people with HSAs can also use a limited-purpose FSA for dental and vision expenses. This combination lets them preserve HSA funds for future growth while still using pre-tax money for routine costs.
Check whether your plan allows you to contribute directly as well as through payroll. If you leave a job or your employer does not offer payroll contributions, you can usually still fund the account yourself and claim the deduction when you file your tax return.
Using an HSA as a Long-Term Savings Tool
Many savers use their HSA as a long-term investment account. Instead of spending the balance each year, they pay current medical bills out of pocket and leave the HSA invested to grow.
There is no deadline for reimbursing yourself for qualified expenses incurred after the HSA was opened. If you keep receipts, you can withdraw money tax-free years later to cover those past costs.
After age 65, HSAs become even more flexible. Withdrawals for non-medical expenses are no longer penalized, though they are taxed as ordinary income, similar to a traditional retirement account.
Medical costs often rise in retirement. An invested HSA can help pay Medicare premiums, prescriptions and other healthcare expenses tax-free, easing pressure on other retirement savings.
Before age 65, non-medical withdrawals are subject to income tax and a 20 percent penalty. That makes it important to use HSA funds only for qualified expenses during your working years.
Getting the Most From Your HSA
Contribute at least enough to receive any employer contribution. Like a retirement match, this is free money that immediately increases your savings.
Keep a cash cushion in the account for near-term medical costs, then invest the remainder. Many providers require a minimum cash balance before investing, so check the rules of your plan.
Choose low-cost investment options. Broad index funds with low expense ratios help maximize long-term growth, just as they do in retirement accounts.
Save receipts for medical expenses in a digital folder. Organized records make future reimbursements simple and provide documentation if the IRS ever asks.
An HSA can serve as both a safety net for medical bills and a powerful retirement savings tool. Understanding the rules lets you take full advantage of its unique tax benefits.
