The Kenai Peninsula Borough will ask voters several big questions on October 4th. The first of which asks: should the seasonal sales tax exemption of non-prepared food items from borough sales tax continue? Since January 1, 2009, non-preapared food has been exempted from borough sales tax between September 1 and May 31 each year. The other big question is: should the borough sales tax be increased from 3.0% to 3.1%, beginning January 1, 2012? Before the borough would be allowed to collect this tax, there must be agreement with all of the cities within the borough.
