Newtown officials are looking at a modest tax rate increase in the coming fiscal year. First Selectman Dan Rosenthal said during a meeting last week that he never likes spending money or having a tax increase, but the proposed school and municipal budgets would result in a .5 percent increase. The proposed municipal budget is $45.7 million, a 5-percent increase over the current year, while the schools are looking for $83 million, a 4.35 percent increase. Rosenthal says growth in the town’s tax base, including an unexpected jump in the motor vehicle grand list, may help offset new spending. The budget review process will include public hearings and a referendum.
