What is an HSA, and why is it called triple exempt?

Direct answer An account for people on a high-deductible health plan. Federally the contribution is deductible, the growth is untaxed, and withdrawals for medical costs are untaxed, hence triple exempt. The 2026 family limit is $8,750. California does not conform and taxes the contributions and earnings every year.

After age 65 non-medical withdrawals are taxed like a traditional IRA, so the account doubles as retirement space. Read California taxes the HSA every year.

What that costs, and the bill that would change it. Fill the sheltered slots before adding taxable money A dollar inside a shelter never meets the 52% short-term rate or the yearly dividend tax. The 2026 limits, the two back doors for high earners, and one Californian catch. Four accounts, three tax treatments Taxable, traditional IRA or 401(k), Roth, HSA. Each taxes the same dollar of return at a different time and a different rate. One table, then the one rule that follows from it.
