HSA Contribution Calculator
See your HSA contribution limit (based on self-only or family HDHP coverage and your age) and the total tax savings from contributing the maximum. HSAs have a triple tax advantage: pre-tax contributions, tax-free investment growth, and tax-free withdrawals for qualified medical expenses.
How is this calculated?
2025 contribution limits: $4,400 self-only HDHP, $8,750 family HDHP, plus a $1,000 catch-up if you’re 55+. Federal income tax savings = limit × your federal marginal rate. State savings depend on your state — most follow federal treatment, but California and New Jersey tax HSA contributions at the state level. Cafeteria-plan contributions (made via payroll deduction) also save the 7.65% employee FICA share. HDHP eligibility requires a deductible of at least $1,700 self / $3,400 family with max OOP $8,500/$17,000 — check your plan.
Frequently Asked Questions
Why is the HSA called a triple-tax-advantaged account?
Three tax-free moments: (1) Contributions reduce your taxable income (pre-tax). (2) Investment growth inside the HSA is never taxed. (3) Withdrawals for qualified medical expenses are tax-free. After age 65, you can withdraw for any reason without penalty (taxed as ordinary income for non-medical, like a Traditional IRA).
What counts as a qualified medical expense?
Most out-of-pocket medical, dental, and vision expenses for you, your spouse, and dependents — even if they're not on your HDHP. IRS Pub 502 lists the full set. Includes copays, prescriptions, eyeglasses, dental work, mental-health services. Health insurance premiums generally don't qualify (exceptions: COBRA, long-term care, Medicare premiums after 65).
Should I invest my HSA or keep it as cash?
Most HSA providers let you invest balances above a small minimum (typically $1,000-$2,000) in mutual funds or ETFs. If you can pay current medical costs out of pocket and let the HSA grow, it becomes a stealth retirement account — you're getting decades of tax-free compounding. Save your medical receipts; you can reimburse yourself decades later, tax-free.
What if I'm no longer on an HDHP?
Your existing HSA balance stays yours forever — you just can't contribute new money. You can still withdraw tax-free for qualified medical expenses. If you want to contribute again in future, just need to be on an HDHP again (and not enrolled in any disqualifying coverage like Medicare or a non-HSA-compatible FSA).
