In mid-December, Congress renewed a long list of tax breaks known as “extenders” that have been expiring on an annual basis. This year many of the rules are retroactive to the beginning of 2015, and you can benefit from them as you prepare your 2015 federal income tax return. In addition, the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015, makes some of the rules effective through December 31, 2016. Others are effective through 2019, and some are effective permanently. Provisions in the Act also make changes to existing tax rules that were not part of the extenders. All of these changes will affect your tax planning for 2016 and future years. Here’s an overview of selected provisions.
