The Tax Cuts and Jobs Act, a $1.5 trillion tax cut package, was signed into law on December 22, 2017. The centerpiece of the legislation is a permanent reduction of the corporate income tax rate. The corporate rate change and some of the other major provisions that affect businesses and business income are summarized below. Provisions take effect in tax year 2018 unless otherwise stated.
Corporate Tax Rates
- Instead of the previous graduated corporate tax structure with four rate brackets (15%, 25%, 34%, and 35%), the new legislation establishes a single flat corporate rate of 21%.
- The Act reduces the dividends-received deduction (corporations are allowed a deduction for dividends received from other domestic corporations) from 70% to 50%. If the corporation owns 20% or more of the company paying the dividend, the percentage is now 65%, down from 80%.
- The Act permanently repeals the corporate alternative minimum tax (AMT).
