#TrumpTaxCuts #Most of the changes introduced by the bill went into effect on January 1, 2018, and did not affect 2017 taxes.[8] Many tax cut provisions contained in the TCJA, notably including individual income tax cuts, such as the changes to the standard deduction in §63 of the IRC, are scheduled to expire in 2025 while many of the business tax cuts expire in 2028.[9][10] Extending the cuts have caused economists across the political spectrum to worry it would boost inflationary pressures[11][12] and worsen America's fiscal trajectory.[13] The Congressional Budget Office estimates that extending the expiring provisions would add $4.6 trillion in deficits over 10 years.[14]
