Some of your medical expenses may be tax deductible, but only if you itemize deductions and have enough expenses to exceed the applicable floor for deductibility. With proper planning, you may be able to time controllable medical expenses to your tax advantage. The Tax Cuts and Jobs Act (TCJA) could make bunching such expenses into 2018 beneficial for some taxpayers. At the same time, certain taxpayers who’ve benefited from the deduction in previous years might no longer benefit because of the TCJA’s increase to the standard deduction.
The changes
Various limits apply to most tax deductions, and one type of limit is a “floor,” which means expenses are deductible only to the extent that they exceed that floor (typically a specific percentage of your income). One example is the medical expense deduction.
Because it can be difficult to exceed the floor, a common strategy is to “bunch” deductible medical expenses into a particular year where possible. The TCJA reduced the floor for the medical expense deduction for 2017 and 2018 from 10% to 7.5%. So, it might be beneficial to bunch deductible medical expenses into 2018.
