This legislation made substantial changes to municipal income tax effective with the 2016 tax year.  As a result, municipalities throughout the State were required to pass new income tax ordinances to be in compliance with the new laws.  The City of Blue Ash finalized its new ordinance on November 12, 2015.  Below are some notable changes in the City’s ordinance:
  • Withholding due dates changed as well as thresholds to determine quarterly and monthly filers.  

  • Estimated payment due dates changed as well as the threshold requiring quarterly estimated payments.  

  • Penalties and interest changed to be uniform throughout the State.  

  • Filing Requirements for residents of Blue Ash changed.*

  • Occasional entrant rules expanded from 12 to 20 days.

  • Net operating loss carryforward calculations will change effective with losses incurred in the 2017 tax year.

*Beginning with tax year 2016, all residents 18 and over will be required to file a Blue Ash tax return regardless of whether tax is owed.  The first mandatory filing will be due by April 18, 2017.
