Calculate your HSA tax savings, investment growth, and retirement healthcare costs. See the triple tax advantage in real dollars, contributions, growth, and withdrawals all tax-free. Updated IRS limits.
The HSA is the only account with a triple tax advantage: contributions reduce taxable income, growth is tax-free, and withdrawals for medical expenses are tax-free. After age 65, you can withdraw for any purpose (paying ordinary income tax, like a traditional IRA).
HSAs and FSAs both let you pay medical costs with pre-tax dollars, but they have important differences. The right choice depends on your health plan, how much you spend on healthcare, and your long-term goals.

A Health Savings Account (HSA) is the only account in the US tax code that offers three layers of tax advantage: contributions are tax-deductible (reducing taxable income now), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. No other account (not a 401(k), not a Roth IRA) offers all three. This makes the HSA a uniquely powerful tool when used strategically. The strategic insight most HSA holders miss: you don't have to spend your HSA money on current medical expenses. You can invest HSA funds in mutual funds (most providers offer this option after a threshold balance), let them grow tax-free for decades, and withdraw for medical expenses at any age with no tax. Better yet, after age 65, you can withdraw for ANY purpose and pay only ordinary income tax, effectively making the HSA a backup IRA. Keep your medical receipts for years of qualified expenses you paid out of pocket, then reimburse yourself from the HSA later. For 2024, HSA contribution limits are $4,150 for individual coverage and $8,300 for family coverage. People 55 and older can contribute an additional $1,000 catch-up contribution. To contribute to an HSA, you must be enrolled in a qualifying High Deductible Health Plan (HDHP), defined as a plan with a minimum deductible of $1,600 (individual) or $3,200 (family).
A Health Savings Account (HSA) is arguably the most powerful tax-advantaged account in the US tax code. Unlike a 401(k) or Roth IRA, which have only a single tax benefit, HSAs offer a triple tax advantage: contributions reduce your taxable income, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free. No other account type offers all three.
1. Contributions reduce taxable income. Every dollar you contribute to an HSA reduces your federal and state taxable income. If you're in the 22% federal bracket and contribute $4,400, you save $968 in federal income tax. If your state has income tax, you save even more. If contributions are made through payroll, you also avoid FICA taxes (7.65% on up to the Social Security wage base), saving an additional $336.
2. Growth is completely tax-free. Unlike a taxable brokerage account where you pay capital gains and dividend taxes each year, HSA investments grow without any tax drag. Over 25 years at 7% returns, $4,400 per year grows to approximately $300,000, entirely tax-free if used for medical expenses.
3. Qualified withdrawals are tax-free. Medical expenses paid with HSA funds are never taxed, not when the money went in, not when it grew, and not when it comes out. Qualified expenses include deductibles, copays, prescriptions, dental, vision, LASIK, hearing aids, mental health, and hundreds of other medical costs.
| Coverage | 2024 Limit | 2025 Limit | 2026 Limit | Change |

| Self-Only | $4,150 | $4,300 | $4,400 | +$100 |
| Family | $8,300 | $8,550 | $8,750 | +$200 |
| Catch-Up (55+) | $1,000 | $1,000 | $1,000 | No change |
| Self-Only + Catch-Up | $5,150 | $5,300 | $5,400 | +$100 |
| Family + Catch-Up | $9,300 | $9,550 | $9,750 | +$200 |
Three states do not conform to the federal HSA tax treatment: California, New Jersey, and Alabama. Residents of these states must pay state income tax on HSA contributions and investment gains, though federal tax benefits still apply. If you live in one of these states, your HSA tax savings are lower than for most Americans, but the federal and FICA savings are still significant.
HSA funds can be used for a wide range of medical expenses including deductibles and copays, prescription medications, dental care (including orthodontia), vision care (glasses, contacts, LASIK), mental health services, chiropractic care, hearing aids, medical equipment, and long-term care insurance premiums. Since 2020, over-the-counter medications no longer require a prescription to qualify. Menstrual care products were added as qualified expenses in 2020.
