The HSA in 2026: $4,400 single, $8,750 family, and the only account taxed zero times
Contributions are deducted, growth is untaxed, and withdrawals for medical costs are tax-free. Through payroll, the contribution also skips Social Security and Medicare tax. Nothing else does all four.
A health savings account is the only account in the U.S. tax code where money goes in untaxed, grows untaxed, and comes out untaxed. The condition is that it is spent on qualified medical expenses, and the condition has a feature most people miss: there is no deadline on when.

The three tax breaks, in dollars
A family contributing the full $8,750 in the 24% federal bracket, through payroll.
Income tax: $8,750 × 24% = $2,100. Because payroll contributions are also excluded from Social Security and Medicare tax, a further $8,750 × 7.65% = $669. A contribution made directly rather than through payroll gets the first saving but not the second. State tax varies; California and New Jersey do not recognise HSAs at all.
- Second break: the balance can be invested, and gains are not taxed.
- Third break: withdrawals for qualified medical expenses are not taxed. Ever.
The receipt strategy
The rule is that a withdrawal is tax-free if it reimburses a qualified expense incurred after the account was opened. It does not say the reimbursement has to happen in the same year. An account holder who pays a $300 dental bill from their current account in 2026 and keeps the receipt can withdraw $300 tax-free in 2046, after twenty years of untaxed growth on the money that stayed in.
After age 65, withdrawals for any purpose are taxed as ordinary income with no penalty — the same treatment as a traditional IRA — while medical withdrawals stay tax-free. Since medical costs are the largest single category of retirement spending for most households, the label is rarely a constraint.
The conditions that bite
- The plan has to qualify. A high deductible is a real cost: the first $1,700 or $3,400 of care each year is paid in full. For a household with regular medical spending, the premium saving on a high-deductible plan may not cover it. The account's tax value is not a reason to choose the wrong insurance.
- Medicare ends eligibility. Enrolling in any part of Medicare stops contributions — and enrolment can be backdated six months, which catches people who contribute in the year they turn 65.
- Non-medical withdrawals before 65 are taxed and carry a 20% penalty.
