Drew Sanders, Marion County Assessor, says that the deadline for the business property tax credit application is approaching. He says January 15 is the deadline, but postmarks of that date will not be considered timely filed. THe Business Property Tax credit is a credit against taxes based on valuation for commercial, industrial and railroad classed property units. Sanders says the credit is first available for the 2013 valuations, for which taxes will be payable in September 2014 and March 2015. He adds the only items to fill in are the contact information at the top of the form, and then sign and date it and return it in the pre-addressed envelope that was included with the application.
