On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act, a sweeping $1.5 trillion tax-cut package that fundamentally changes the individual and business tax landscape. While many of the provisions in the new legislation are permanent, others (including most of the tax cuts that apply to individuals) will expire in eight years. Some of the major changes included in the legislation that affect individuals are summarized below; unless otherwise noted, the provisions are effective for tax years 2018 through 2025.
Individual income tax rates
The legislation replaces most of the seven current marginal income tax brackets (10%, 15%, 25%, 28%, 33%, 35%, and 39.6%) with corresponding lower rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The legislation also establishes new marginal income tax brackets for estates and trusts, and replaces existing "kiddie tax" provisions (under which a child's unearned income is taxed at his or her parents' tax rate) by effectively taxing a child's unearned income using the estate and trust rates.
