The Board of Selectmen will hold its annual tax-classification hearing on Nov. 7. State law requires all municipalities to hold such hearings each year to determine whether to set different tax rates for residents and businesses. Based on the selectmen’s decision, the Board of Assessors will set a tax rate or rates for fiscal 2014, which began July 1, subject to approval from the state Department of Revenue. Norton has always had a single tax rate. In fiscal 2013, the rate was $14.92 per $1,000 valuation. The Nov. 7 hearing will be held at 7:30 p.m. as part of the selectmen’s meeting that night, which starts at 7 p.m.
