Most of the new changes are for 2018 returns we file next year in 2019.  The one big change for 2017 was the medical deduction went from 10% AGI threshold down to 7.5% for everyone.  But Turbo Tax had made that change.

So this --> In 2017, the standard deduction for a single taxpayer is $6,350, plus one personal exemption of $4,050. The new law combines those into one larger standard deduction for 2018: $12,000 for single filers and $24,000 for joint filers.

The Standard deduction wont be 12,000 take affect for the 2017 taxes? Or only on the 2018 taxes moving forward.

Only starting with 2018 returns filed in 2019.
