The Tax Bill that was just passed limits deductions for state and local property, income and sales taxes to $10,000 starting in 2018. Pay before midnight on December 28 and you'll likely still get these deductions in 2018 (no guarantees, though). See below for more info on how to decide if paying your property taxes by 11:59pm on Thursday, 12/28 deadline is right for you. We also suggest that you speak with your accountant.
