HSAs and FSAs, explained

Pre-tax money for medical costs, with different rules.

6 min read

Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) let you pay for eligible medical costs with pre-tax money. They work quite differently.

HSA

  • Only with an HSA-eligible high-deductible health plan
  • The money is yours and rolls over every year, even if you change jobs
  • Can often be invested
  • Withdrawals for qualified medical costs are tax-free

FSA

  • Offered through an employer
  • Generally "use it or lose it" by the end of the plan year, though some plans allow a small carryover or a grace period
  • The full yearly amount may be available early in the year

Contribution limits change each year; see IRS.gov or your benefits guide.
