Paying medical bills with an HSA: what the IRS says
The IRS says distributions from an HSA used to pay qualified medical expenses aren't taxed. Use it for other things and the money is taxable, plus an extra 20% tax.

The three rules to remember
- Qualified medical expenses are tax-free. Distributions used for them aren't taxed.
- Timing matters. Expenses incurred before you establish your HSA aren't qualified medical expenses, so a bill from before you opened the account can't be paid tax-free from it.
- Other withdrawals are taxed. Distributions not used for qualified medical expenses are taxable income, and there is an additional 20% tax on that part. Publication 969 lists exceptions, so read it or ask a tax professional.
Using it on a hospital bill
- Pay after you have the final bill and your insurer has processed it. Check the itemized bill first.
- Keep the bill, the EOB, and proof of payment with your tax records.
- Ask about financial assistance before you spend HSA funds on a bill that might be reduced.
One more thing
If you also itemize deductions, read the IRS rules on deducting medical expenses so you don't count the same expense twice. Ask a tax professional how the two interact for you.
