Can I Use HSA Funds for Old Medical Bills? | Understanding HSA Rules

One common question that arises among HSA account holders is whether they can use their HSA funds to pay for old medical bills. The answer to this question depends on several factors and understanding the rules surrounding HSA contributions and withdrawals.

Here is a breakdown of the key points to consider:

  • HSAs can be used to pay for qualified medical expenses incurred after the HSA was established.
  • Old medical bills that were incurred before opening an HSA are generally not eligible for payment using HSA funds.
  • However, you may still be able to reimburse yourself for past medical expenses if those expenses were incurred after the HSA was established.
  • To do this, you must have receipts or documentation of the medical expenses, and the expenses must have occurred after the HSA was opened.
  • It's important to keep accurate records of your medical expenses and HSA transactions to ensure compliance with IRS regulations.

Overall, while you cannot use HSA funds to pay for old medical bills incurred before opening an HSA, you may be able to reimburse yourself for past expenses if they meet certain criteria.


Many HSA holders often wonder if they can access HSA funds for medical bills that predate their account opening. The straightforward answer is that HSA funds are intended for expenses incurred after the account is established.
