WASHINGTON — Arlington will see a 0.25 percent increase in the “transient occupancy” tax — or lodging tax — after the county board unanimously approved the measure on Saturday.

The guest-paid tax increase, starting on July 1, could bring in about $1.25 million in revenue for the county’s tourism and travel promotion, according to the board.

The county’s authority on the tax had expired in 2011 and was only recently approved in this year’s Virginia General Assembly.

“This bi-partisan effort will give us additional revenue to promote travel and tourism in Arlington, creating economic benefit not only for our community, but the entire state,” Arlington County Board Chair Libby Garvey said in a statement.
