Can I Use HSA Money for Prior Year Expenses? - Understanding HSA Rules and Benefits

Many people wonder if they can use their HSA (Health Savings Account) money for expenses from previous years. The answer is not straightforward, but it's essential to know how HSA rules work to make the most of this unique savings account.

Generally, HSA funds can only be used for medical expenses that occur after the HSA is established. However, there are some exceptions that allow you to use HSA money for prior year expenses:

  • If the expense was incurred after you opened the HSA but before you funded it, you can reimburse yourself from the HSA once you have the account set up.
  • If you paid out-of-pocket for a qualified medical expense in a previous year and saved the receipt, you can reimburse yourself from the HSA at any time as long as the expense was incurred after the HSA was established.

It's important to keep detailed records and receipts when using your HSA to reimburse yourself for prior year expenses to avoid any confusion or IRS scrutiny. While HSA rules can be complex, understanding them can help you maximize the tax advantages and flexibility that come with using an HSA.


One frequent question among HSA account holders is whether they can use their HSA money for medical expenses incurred in previous years. While the standard rule is that HSA funds must be allocated for expenses that occur after the account is established, there are specific guidelines that give you some flexibility.
