Congress passes biggest tax bill since 1986 | Gerson Preston

January 10, 2018


On December 20, the House passed the Tax Cuts and Jobs Act of 2017 (TCJA), which the Senate had passed the previous day. It’s the most sweeping tax legislation since the Tax Reform Act of 1986.

The bill makes small reductions to income tax rates for most individual tax brackets, significantly reduces the income tax rate for corporations and eliminates the corporate alternative minimum tax (AMT). It also provides a large new tax deduction for owners of pass-through entities and significantly increases individual AMT and estate tax exemptions. And it makes major changes related to the taxation of foreign income.

It’s not all good news for taxpayers, however. The TCJA also eliminates or limits many tax breaks, and much of the tax relief is only temporary.

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

Key changes affecting individuals

Year-end planning opportunities still available

We’ve only briefly covered some of the most significant TCJA provisions here. There are additional rules and limits that apply, and the law includes many additional provisions.

Also keep in mind that, 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.
