The TCJA Permanency Act makes permanent several tax provisions that were enacted as part of the 2017 Tax Cuts and Jobs Act (TCJA) and were set to expire. These provisions include modifications to individual income tax rates and brackets, the standard deduction, the child tax credit, and the estate and gift tax exemption. The act also increases the exemption for the Alternative Minimum Tax (AMT) and adjusts the phase-out thresholds. Additionally, it includes various changes affecting deductions, credits, and exclusions for individuals, families, businesses, and estates.
