How much tax does an HSA save?
Contributing the maximum $4300 (individual) saves you taxes at your marginal rate. At the 24% bracket you save $1032 in federal tax. Adding state tax savings (5-10% in most states) the total savings can reach $1300-$1500 per year. Over 20 years of maximum contributions with investment growth your HSA could reach $250000+ all tax-free for medical expenses.
Should I invest my HSA or keep it in cash?
If you can afford to pay current medical expenses out of pocket invest your HSA in low-cost index funds for long-term growth. An HSA invested at 8% returns for 20 years grows far more than one kept in cash. Keep 1-2 years of expected medical costs in cash and invest the rest. Save your medical receipts to reimburse yourself tax-free at any point in the future even decades later.
Can I use HSA for retirement?
Yes after age 65 you can withdraw HSA funds for any purpose without penalty. Non-medical withdrawals are taxed as regular income similar to a traditional IRA. For medical expenses withdrawals remain completely tax-free at any age. This makes HSA a powerful hybrid: tax-free healthcare fund now and supplemental retirement account later.
