What's New for 2017 tax year

The "Tax Cuts and Jobs Act" (TCJA) passed in December won't affect 2017 returns hardly at all. The only effect to note is that the threshold for deducting medical expenses has been rolled back to 7.5% for 2017 and 2018. The floor figure had jumped to 10% two years ago, and will return to 10% in 2019.

Because April 15 falls on a weekend again this year, the filing deadline will be Tuesday, April 17.
