With the recent passing of the Tax Cuts and Jobs Act (TCJA), the most significant reform of the U.S. tax code since 1986, you may be wondering how this affects you as an individual or your business or partnership operating in the U.S. or abroad. Here is an overview of the key changes affecting individual and business taxpayers.

However, keep in mind, these changes are only effective for tax years beginning after December 31, 2017 unless noted below.
