ROCKLAND, Maine — Local tax bills that are 2.5 percent higher than last year should be arriving in mailboxes by next week.

The city set the tax rate Tuesday at $21.72 per $1,000 of assessed property valuation. This is up 2.5 percent from $21.20 set in 2015.

A person owning a home assessed at $150,000 can expect to pay an additional $78 in taxes, up from $3,180 to $3,258.

The amount of money going to Regional School Unit 13 accounts for a majority of the property taxes in Rockland. Of the $16.9 million that Rockland will be raising in property taxes, $8.8 million, or 52 percent, will go to the school district. That amount for schools is about $60,000 more than last year.

Nearly $7.3 million, or 43 percent, in property taxes is needed to support the municipal budget, which pays for services such as police, fire, emergency medical services, public services, recreation, library and waterfront activities. This is about $300,000 more than last year. Some of the increased reliance on property taxes is because of a reduction in state aid.

The remaining $764,000, or 5 percent, goes to Knox County for services such as the sheriff’s patrol, jail operations and the airport. Rockland’s payment to Knox County increased by about $34,000 from last year.

The city’s overall valuation dropped by nearly $3 million from last year to $778 million.
