MISSOULA, Mont. -

Montana officials say they are losing millions in revenue each year because of the large number of unlicensed short-term vacation rentals that don't pay state lodging or resort taxes.
    
Department of Revenue spokeswoman Mary Ann Dunwell says those who aren't paying their share of taxes are depriving the state of money that could be used to improve the quality of life.
    
The loss in revenue could amount to $4 million a year.
    
The state has issued licenses for 657 vacation rental homes. That is less than a quarter of the more than 2,700 individual properties in Montana listed on the two sites managed by HomeAway.
    
HomeAway is one of the world's largest online markets for vacation rentals.
