The Tax Reform Law of 2017 made changes that affect every taxpayer. Most of those changes went into effect last year. A few are new for 2020, when you are required to file your 2019 federal income taxes.
The Tax Cuts and Jobs Act of 2017 made big changes to how the government calculates your income taxes. Most of the changes took effect last year and applied to your 2018 federal tax return. But a few changes go into effect this year, and apply for the first time to your 2019 return. The Internal Revenue Service also made adjustments for inflation to some deductions, credits, and tax brackets.
