Why is my non-taxable tax code taxing in Colorado


The Non-taxable tax code you're using is taxing unexpectedly

  • Since Colorado is a home ruled state were local jurisdictions determine the taxability even though a tax code is exempt at the state level it can still be taxable at the city level.
  • For example the tax code SW054000 for the zip code 80303 it's exempt on all levels except Boulder City tax (7/31/2015)
