A fundamental tax planning strategy is to accelerate deductible expenses into the current year. This typically will defer (and in some cases permanently reduce) your taxes. But there are exceptions. One is if the additional deductions this year trigger the alternative minimum tax (AMT). Complicating matters for 2017 is the fact that tax legislation might be signed into law between now and year end that could affect year-end tax planning. For example, as released by the Ways and Means Committee of the U.S. House of Representatives on November 2, the Tax Cuts and Jobs Act would repeal the AMT for 2018 and beyond. But the bill would also limit the benefit of some deductions and eliminate others.
