About This Tool

The HSA Calculator shows you exactly how much you save in taxes by contributing to a Health Savings Account, and projects how your balance can grow over time when invested. It uses 2026 contribution limits ($4,300 individual, $8,550 family) and accounts for federal income tax, FICA taxes, and state income tax savings.

The Triple Tax Advantage

An HSA is the only account in the US tax code with a triple tax benefit. Contributions reduce your taxable income (saving you federal, state, and FICA taxes). Investment growth is completely tax-free — no annual taxes on dividends, interest, or capital gains. And withdrawals for qualified medical expenses are tax-free. No 401(k), IRA, or Roth account offers all three benefits simultaneously.

HSA as a Retirement Strategy

Many financial advisors now recommend maxing out your HSA before contributing beyond your 401(k) employer match. The strategy: pay current medical expenses out of pocket, invest your HSA funds for long-term growth, and save receipts. There's no time limit on reimbursement — you can pay yourself back decades later for expenses you paid out of pocket today. After age 65, you can withdraw for any reason (taxed as income, no penalty), making it function like a traditional IRA as a backup.

2026 Contribution Limits

The IRS sets HSA contribution limits annually, adjusted for inflation. For 2026, the limits are $4,300 for self-only coverage and $8,550 for family coverage. If you're 55 or older, you can contribute an additional $1,000 catch-up amount. These limits include both your contributions and any employer contributions. Exceeding the limit triggers a 6% excise tax on the excess for each year it remains in the account.

State Tax Considerations

Most states follow the federal tax treatment of HSA contributions, meaning your contributions reduce state income tax too. However, California and New Jersey do not recognize HSA tax benefits at the state level — you'll still owe state tax on contributions and investment earnings in those states. Alabama and Wisconsin have partial non-conformity. Check your state's specific HSA treatment, or set the state tax rate to 0% in the calculator if your state doesn't offer the deduction.

Frequently Asked Questions

What are the 2026 HSA contribution limits?
For 2026, the HSA contribution limit is $4,300 for individual coverage and $8,550 for family coverage. If you're 55 or older, you can contribute an additional $1,000 catch-up amount. These limits include both employee and employer contributions. Exceeding the limit triggers a 6% excise tax on the excess amount.
What is the triple tax advantage of an HSA?
HSAs offer three tax benefits that no other account provides: (1) Contributions are tax-deductible, reducing your federal income tax, state tax (in most states), and FICA taxes. (2) Growth is tax-free — investments earn returns without annual tax on dividends or capital gains. (3) Withdrawals for qualified medical expenses are tax-free. After age 65, you can withdraw for any purpose (taxed as income, like a traditional IRA) with no penalty.
Can I invest my HSA funds?
Yes, most HSA providers offer investment options once your cash balance reaches a threshold (often $1,000-$2,000). You can invest in mutual funds, ETFs, and other options similar to a 401(k). For long-term HSA holders who pay current medical expenses out of pocket, investing HSA funds for decades of tax-free growth is one of the most powerful retirement strategies available.
What qualifies as an HSA-eligible expense?
Qualified medical expenses include doctor visits, prescriptions, dental care, vision care, mental health services, and many over-the-counter medications and supplies. The IRS maintains the full list in Publication 502. Non-qualified withdrawals before age 65 incur income tax plus a 20% penalty. After 65, non-qualified withdrawals are taxed as ordinary income with no penalty.
Do I lose my HSA funds if I change jobs or health plans?
No. Unlike a Flexible Spending Account (FSA), HSA funds are yours forever. There's no 'use it or lose it' rule. If you change jobs, your HSA comes with you. If you switch to a non-HDHP plan, you can't contribute new funds but can still use and invest existing money. The account stays open indefinitely.
