New law creates retroactive tax break
The Tax Cuts and Jobs Act (TCJA) repeals or cuts back many deductions on personal returns (see “Last Chance for Key Tax Deductions”), but the medical expense deduction survived the chopping block. In fact, the new law temporarily enhances the deduction, retroactive to the 2017 tax year. In other words, you can benefit from this tax-favored treatment on the 2017 return you file in 2018.
