Congress Passes Tax Cuts and Jobs Act of 2017

The most sweeping tax legislation since the Tax Reform Act of 1986 was passed by the House on December 20. The House passed the reconciled tax reform bill, H.R.1, commonly called the “Tax Cuts and Jobs Act of 2017” (TCJA), which the Senate had passed the previous day.

The bill focuses on several key components. It:

  • Significantly reduces the income tax rate for corporations
  • Eliminates the corporate alternative minimum tax (AMT)
  • Includes reductions to income tax rates for most individual tax brackets
  • Provides a new tax deduction for owners of pass-through entities and significantly increases individual AMT and estate tax exemptions
  • Makes major changes related to the taxation of foreign income
  • In addition, there are also significant changes for taxpayers. The TCJA eliminates or limits many tax breaks, and much of the tax reduction expires after 2025.


Here is a summary of some of the key changes affecting business and individual taxpayers. Except where noted, these changes are effective for tax years beginning after December 31, 2017.


Key changes affecting businesses

  • Replacement of graduated corporate tax rates ranging from 15% to 35% with a flat corporate rate of 21%
  • Repeal of the corporate AMT

Only some of the most significant TCJA provisions are covered here. There are additional rules and limits that apply, and the law includes many other provisions. Also, keep in mind, as a result of the TCJA, you may have some last-minute year-end 2017 tax planning opportunities — but quick action before January 1, 2018 will be needed. If you have questions about what you can do before year-end to maximize your tax savings, or if you would like to learn more about how these and other tax law changes will affect you in 2018 and beyond, please contact your Saville professional.
