Various limits apply to most tax deductions, and one type of limit is a “floor,” which means expenses are deductible only if 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. If tax reform legislation is signed into law, it might be especially beneficial to bunch deductible medical expenses into 2017.

A tried-and-true tax-saving strategy for investors is to sell assets at a loss to offset gains that have been realized during the year. So if you’ve cashed in some big gains this year, consider looking for unrealized losses in your portfolio and selling those investments before year end to offset your gains. This can reduce your 2017 tax liability.
