Alna’s new property tax rate is down nearly 10 percent from last year, for a difference that will drop a bill on a $100,000 home by $220.

Selectmen set the rate Sept. 23, delivering on their prediction of a drop after the town hiked its values for Central Maine Power properties. In August, the board followed assessing contractor William Van Tuinen’s recommended increases in values on CMP’s poles, lines and land.

At the time, the board tempered the size of the potential drop in the tax rate due to slightly higher town and county costs. But officials Sept. 23 said a drop in Regional School Unit 12’s bill and a boost in surplus funds and excise taxes joined with the CMP changes to help make the new tax rate of $20.60 per thousand dollars of assessed valuation.

First Selectman David Abbott said that 80 percent of a $152,000 surplus was used to offset taxes.

“It’s awesomeness,” Town Clerk Amy Warner said about this year’s rate drop.

The 2014 tax rate was $22.80 per thousand dollars.

The new rate puts the bill for a $100,000 home at $2,060 compared to $2,280 in 2014.

The 2015 rate represents the first drop the Alna rate has had in years. The 2013 rate was $22.65, the 2012 one, $21.80.

Plans called for tax bills to go in the mail Sept. 25, with payment due Nov. 10, town officials said.

A CMP spokesman has said the company would be reviewing the new assessment in Alna.

“CMP will get the bill and we shall see,” Third Selectman Doug Baston said when the board signed the tax commitment on Sept. 23. “We assume they’ll be good corporate citizens and pay the bill.”
