One of the benefits of an HSA is that you can use your funds for any qualified medical expense, without any restrictions or penalties. However, this also means that you have to be responsible and prudent with how you use your money. Some common mistakes that people make are using their HSA funds for non-medical expenses, such as groceries, clothing, or entertainment, which are subject to taxes and penalties; using their HSA funds for medical expenses that are not qualified, such as cosmetic surgery, over-the-counter drugs, or vitamins, which are also taxable and penalized; or using their HSA funds too soon, when they could have paid out of pocket and saved their funds for later. To avoid these mistakes, you should always check the IRS list of qualified medical expenses before using your HSA funds, keep your receipts and records for tax purposes, and plan ahead for your current and future medical needs.
