A reader reminds me of a little-noticed tax increase adopted by the last 2003 legislature, but just now about to take effect (thanks Steve Harrelson for correction). It removes the $2,500 cap on application of local sales taxes, except on sales of cars, boats, planes and mobile homes. For example, as the illustration shown on the state's information sheet indicates, a $3,000 plasma TV in Fayetteville now costs about $16 more because the full local sales taxes apply.
(Hey, here's a bonus for oppo researchers. Another tax increase to lay on the Huck.)
