FILE- This July 24, 2018, file photo shows a portion of the 1040 U.S. Individual Income Tax Return form for 2018 in New York. A new rule caps the state and local taxes you can deduct on your federal tax return. That could make more of your income taxable this year, but finding out if the cap affects you, pouncing on other tax breaks, bunching your charitable contributions and planning for a new tax world could help.
