by | Dec 27, 2017 | Client Memo, Tax

The new tax reform law, commonly called the “Tax Cuts and Jobs Act” (TCJA), is the biggest federal tax law overhaul in 31 years, and it has both good and bad news for taxpayers.

Below are highlights of some of the most significant changes affecting individual and business taxpayers. Except where noted, these changes are effective for tax years beginning after December 31, 2017.
