(Olympia, WA)  --  Washington state lawmakers are considering a bill that would repeal the state sales tax on classes offered by martial-arts academies.  The nine-point-four-percent sales tax went into effect this year after a law that passed in 2015 re-classified martial-arts instructors as operators of athletic or fitness facilities, rather than providers of instructional services.  The bill was approved last week by the House and now awaits action in a Senate committee.
