34 things you need to know about the incoming tax law

15. If you’re a teacher, you can still deduct classroom supplies.

The deduction for teachers who spend their own money on school supplies was left alone. Educators can continue to deduct up to $250 to offset what they spend on classroom materials.

16. The electric car tax credit lives on.

Drivers of plug-in electric vehicles can still claim a credit of up to $7,500. Just as before, the full amount is good only on the first 200,000 electric cars sold by each automaker. GM, Nissan and Tesla are expected to reach that number some time next year.

17. Home sellers who turn a profit keep their tax break.

Homeowners who sell their house for a gain will still be able to exclude up to $500,000 (or $250,000 for single filers) from capital gains, so long as they’re selling their primary home and have lived there for two of the past five years.

18. 529 savings accounts can be used in new ways.

In the past, funds invested in 529 savings accounts wasn’t taxed — but it could only be used for college expenses. Now, up to $10,000 can be distributed annually to cover the cost of sending a child to a “public, private or religious elementary or secondary school.” This change is a win for Education Secretary Betsy DeVos.

19. And tuition waivers for grad students remain tax-free.

Graduate students still won’t have to pay income taxes on the tuition waiver they get from their schools. Such waivers are typically awarded to teaching and research assistants.
