Yoga and Pilates classes are the latest victims of a state’s dwindling revenue according to this story in the Kansas City Star. Missouri has slapped a 4% sales tax on yoga classes, according to the story, which notes that Missourians could previously take yoga classes tax free because studios argued the stretching and breathing discipline is as spiritual as it is physical. Missouri argues yoga is merely exercise, and therefore subject to taxation.

With states facing the worst revenue declines on record it’s unlikely that a yoga tax is going to bridge the gaping budget holes most states are facing.

But as state and local governments rush to close their revenue gaps amid falling tax collections and dwindling stimulus dollars, you can expect a lot more debates like this one. Maine has expanded taxes on candy, haircuts and lawn care. In Illinois, a candy tax earlier this year threw the state into confusion as to what is candy and what is food. Is margarita mix an additive or a soft drink? Depends on who you ask.
