HSA Calculator

Per IRS Rev. Proc. 2025-19, the 2026 limits are $4,400 for self-only HDHP coverage and $8,750 for family coverage, with an additional $1,000 catch-up contribution at age 55+. You must be enrolled in an HSA-eligible HDHP, not enrolled in Medicare, and not claimed as a dependent.

Contributions are tax-deductible (or pre-tax via payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. After age 65, non-medical withdrawals are taxed as ordinary income (no 20% penalty), making the HSA function like a Traditional IRA - only with extra tax-free flexibility for medical costs.

If you can pay current medical expenses out of pocket, invest your HSA for long-term growth. Devenir's recent HSA market reports show invested HSAs average roughly 5x the balance of non-invested accounts - a powerful retirement tool when you let contributions compound for 20+ years.

For 2026, the IRS defines an HSA-eligible HDHP as: self-only minimum deductible $1,700 (max OOP $8,500) or family minimum deductible $3,400 (max OOP $17,000). The plan must not cover anything before the deductible except preventive care, telehealth, and certain first-dollar items the IRS permits.

No. Enrolling in any part of Medicare ends your eligibility to contribute, though you can still use the existing balance for qualified medical expenses. If you work past 65 and want to keep contributing, it may make sense to delay Medicare Part A.
