Health Savings Account (HSA)

Full explanation

An HSA lets you save pre-tax money for qualified medical expenses. The triple tax advantage: contributions are tax-deductible, growth is tax-free, and withdrawals for medical expenses are tax-free. For 2026: you can contribute up to $4,300 (self-only) or $8,550 (family). Catch-up contribution of $1,000 for age 55+. You must have a High Deductible Health Plan (HDHP) to contribute. Unlike FSAs, HSA funds roll over indefinitely — there's no 'use it or lose it' rule. After age 65, you can withdraw for any purpose (taxed as income, but no penalty).
