HSA strategy

HSA: Triple-Tax-Advantaged Strategy for High Earners

An HSA is the only account that gives you a tax deduction now, tax-free growth, AND tax-free withdrawals for healthcare. No other account does all three.

The short answer

Max-fund the HSA ($4,150 individual / $8,300 family in 2026), invest it in index funds (not the cash sweep), and pay current healthcare costs out of pocket. Keep the receipts. At age 65 (or earlier for qualified medical), reimburse yourself tax-free. A 30-year-old maxing the HSA and investing builds ~$400K of tax-free healthcare money by age 65.

Bottom line

The HSA beats the 401(k), Roth IRA, and brokerage on tax efficiency for medical expenses. The trick is to NOT spend it on current healthcare — invest it and pay out of pocket while young. Requires an HDHP health plan to be eligible.
