Can I Use HSA for Past Expenses? Understanding the Basics of HSA Usage

When it comes to Health Savings Accounts (HSAs), there are certain rules and guidelines that account holders need to follow. One common question that often arises is whether you can use your HSA funds for past expenses.

HSAs are designed to help individuals save for current and future medical expenses, but there are limitations on using the funds for expenses that occurred before opening the HSA account:

  • You cannot use your HSA funds to pay for medical expenses that were incurred before you opened the account.
  • Any expenses that were paid for using non-HSA funds cannot be reimbursed through your HSA account.
  • It is important to keep accurate records of your medical expenses and receipts, as you may need to provide documentation to the IRS to prove that the expenses were incurred after the HSA was established.

However, there are instances where you can reimburse yourself for past expenses using your HSA funds:

  • If you paid for a qualified medical expense out of pocket and did not use your HSA funds at that time, you can save the receipt and reimburse yourself from the HSA later on.
  • There is no time limit on when you can reimburse yourself for past expenses, as long as the expenses were incurred after the HSA was established.

It's important to note that using your HSA for past expenses should be done carefully and in compliance with IRS regulations to avoid any penalties or tax implications.


Many people frequently wonder about the possibility of using their Health Savings Account (HSA) funds for past medical expenses. Unfortunately, the straightforward answer is no—you cannot retroactively apply HSA funds to expenses incurred prior to the establishment of your account. However, if you had an HSA at the time the expense was incurred, you might be able to make a reimbursement request as long as the expenses were qualified medical costs.
