A Health Savings Account (HSA) is a tax-advantaged account available to anyone enrolled in a high-deductible health plan (HDHP). It's often called the only account with a "triple tax advantage": contributions are tax-deductible (or pre-tax through payroll), the account grows tax-free, and withdrawals for qualified medical expenses are never taxed. Unlike a Flexible Spending Account, unused HSA funds roll over every year and stay with you even if you change jobs.
HSA Contribution Limits for 2025
The IRS caps HSA contributions at $4,300 for individual coverage and $8,550 for family coverage in 2025. If you're 55 or older, you can contribute an extra $1,000 catch-up contribution. These limits include both your own contributions and anything your employer adds on your behalf.
Why an HSA Can Double as a Retirement Account
Most people spend their HSA balance on medical bills as they go, but you don't have to. If you can afford to pay current medical expenses out of pocket, letting your HSA balance invest and compound for decades turns it into a stealth retirement account. After age 65, you can withdraw HSA funds for any purpose - not just medical - and pay only ordinary income tax, exactly like a traditional 401(k) or IRA, with no early withdrawal penalty.
