President Trump is poised to sign the recently passed tax bill, and the first question on many folks’ lips is: when will the tax cuts start? Because the legislation is complex, it’s hard to know exactly when it will effect taxpayers across the U.S. Some of the bill’s impact will begin at the start of 2018, though other elements won’t take effect until 2019 and beyond. For instance, when you file your 2017 taxes in April, you’ll already be getting some benefits like lower tax withholding, but other perks won’t show until you file your tax return in April 2019. Luckily for us, the experts at Fortune magazine have broken it all down quite nicely HERE.
