Well for the past 2 years I've had over 25K in itemized deductions. I suspect 2018 I will have much more. I also have an LLC and passive income (rental), which I believe are taxes the same (need to find out). If not I need to think about putting the rental into a separate LLC, but I need to work out how much the personal property taxes will be in Maryland or if I will pay Baltimore's personal property tax for real estate in Maryland even though I live in Calvert. Calvert has one of the lowest personal property taxes (business) in the state (as my accountant says).
Anyway those minor things may have little difference to the lower taxes I may pay next year. I'm on the higher end of the bracket (at least definitely will be next year). But this is the important thing here, we are making assumption that there will be an increase in growth, if not then this tax cut will serious #### things up...
