<prompt> Human: Am I understanding correctly that the new doubling of the standard deduction wont go into effect until April? Does this mean that if I file my 2017 return in say, Febuary - I wont get to use the higher standard deduction?Ill come out of the 28 bracket and go to the new 24 bracket, but when will the new withholding go into effect?Basically I want to delay filing as long as I need to, in order to reap the most benefits from the new Tax law.TIA!  <response>: Your 2017 taxes are unaffected by this law.When you file your 2017 taxes makes no difference in how your 2018 income is taxed.
