I've seen some conflicting information out there, but my office consensus is that 2018 property taxes are deductible if assessed and paid in 2017.
Since the standard deduction will be $24,000 next year, we'll take it versus itemize. Therefore, if my 2017 property taxes have been assessed, I plan on pre-paying them tomorrow. Of course in backwoods Maine, my town office is closed today, so I won't know whether this is possible until tomorrow morning.
Anyone else researched or doing this?
