Do I Need to Keep EOBS in Case of an HSA Audit?

When it comes to managing your Health Savings Account (HSA), keeping track of your Explanations of Benefits (EOBs) is crucial for various reasons, including preparation for a possible HSA audit. While you may wonder if it is necessary to hold onto these documents, the short answer is 'yes.' Here's why:

  • Prove that the expenses were for qualified medical purposes.
  • Support the withdrawals made from your HSA.
  • Provide evidence in case of an audit by the IRS or your HSA provider.

Without EOBs, you may face challenges in demonstrating the legitimacy of your HSA transactions. It's best to keep these documents organized and easily accessible in case you need them for verification purposes.
