HSA: The Most Underrated Account in Personal Finance

The Health Savings Account has an unglamorous name and a genuinely unusual tax structure. It's the only US account offering a break at all three stages: contributions reduce taxable income, growth is untaxed, and withdrawals for qualified medical expenses come out tax-free.

Compare that to a traditional IRA (taxed on the way out) or a Roth (taxed on the way in). The HSA is neither.

The catch, and the limits

You can only contribute if you're enrolled in a qualifying high-deductible health plan. For 2026, that plan must have a minimum deductible of $1,700 for self-only coverage or $3,400 for family coverage, with out-of-pocket maximums capped at $8,500 and $17,000 respectively.

The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, with an additional $1,000 catch-up from age 55.

An HDHP isn't right for everyone. If you have ongoing medical needs, the higher deductible may cost more than the tax benefit returns. That's a health coverage decision first and a tax decision second.

What makes it interesting long-term

Unlike a flexible spending account, HSA balances roll over indefinitely and the account stays yours when you change jobs. Many providers let you invest the balance rather than leaving it in cash.

Which opens a strategy some people use: pay current medical costs out of pocket, leave the HSA invested for decades, and treat it as a dedicated healthcare fund for retirement — when medical costs typically rise.

The age 65 change

Before 65, non-medical withdrawals are taxed as income and carry a 20% additional tax. That's a serious penalty and worth respecting.

After 65, the penalty disappears. Non-medical withdrawals are taxed as ordinary income — effectively making the account behave like a traditional IRA for general use, while remaining tax-free for qualified medical expenses. It becomes strictly more flexible than it was.

Where it fits

A commonly cited ordering is: capture the full employer 401(k) match first, then consider maximising an HSA if you're eligible, then return to other retirement accounts. That's a reasonable framework rather than a rule, and it assumes you can comfortably cover the higher deductible.

One caution: a few states don't conform to the federal treatment, so state tax handling may differ from federal.
