Spending would increase by 3.23 percent under a $34.77 million budget proposal adopted Tuesday by the Tonawanda City School Board.
The amount to be raised through property taxes would be $12 million, an increase of 2.91 percent, which is within the allowable increase under the New York State tax cap.
Superintendent Timothy Oldenburg said the budget is "responsible and conservative" and remains at the tax cap, which will allow residents to be eligible for a state rebate.
The estimated tax rate $18.61 per $1,000 of assessed valuation means an average homeowner in the district, with a home assessed at $92,000, would pay $1,712 in school taxes.
Residents will vote on the budget and elect School Board members May 15.
