An FSA comes out of your paycheck before taxes, which is a great deal, but on most plans whatever you don’t spend by the deadline goes back to your employer. Some plans offer a grace period into March or a small carryover; HSA money never expires. Details in It’s Your Money. On December 31, Your Employer’s Plan May Keep It.

  1. Log in to your FSA portal and note your balance and deadline.
  2. Look for the “FSA or HSA eligible” label on the Amazon product page.

Does HSA money expire?

No. HSA money stays yours year to year.

Don’t leave free money on the table.
