In December 2017, the U.S. government passed a new tax law that would impact the majority of American taxpayers. Dubbed the Tax Cuts and Jobs Act of 2017 (TCJA), the overall tax rate was designed to lower tax liability.
As 2018 is ending, the IRS has released its tax laws for 2019. While there aren't nearly as many changes as there were for 2018, which reflected the sweeping tax law revisions in the Tax Cut and Jobs Act of 2017, there some changes will affect contributions to your retirement funds. The IRS also has changed how it calculates inflation.
