Explain these results

What is not included: possible state income-tax savings, possible payroll-tax savings from payroll contributions, investment growth, or future medical withdrawals.

01

Money goes in with a tax break

Eligible contributions can reduce federal taxable income. You do not need to itemize to claim a qualifying personal contribution.

02

Growth stays untaxed

Interest and investment growth inside the HSA are not taxed federally while they remain in the account.

03

Qualified medical spending is tax-free

Withdrawals for qualified medical expenses can come out free of federal income tax.

Before you contribute

  • You generally need qualifying high-deductible health plan coverage to contribute to an HSA.
  • The 2026 base limits are $4,400 for self-only coverage and $8,750 for family coverage. Employer contributions count toward the same limit.
  • The $1,000 catch-up applies at age 55 or older. A spouse's catch-up must go into that spouse's own HSA.
  • This calculator assumes you are eligible for the full year. Midyear coverage changes can reduce the amount you may contribute.
