Can I deduct medical costs paid through my HSA or MSA?
The IRS won't let you deduct medical expenses paid through your HSA or MSA, as the money in those accounts are already tax-free and deducting them again would be "double-dipping."
However, that doesn't mean you need to get out your calculator when entering your medical expenses.
Instead, enter all your medical expenses—including the ones paid through your HSA or MSA—and we'll automatically subtract your HSA/MSA expenses, which are reported on Form 1099-SA.
Make sure you enter your 1099-SA before entering your medical expenses so the math works out correctly.
