pop-up tax
n.— «If the proposed bill—sponsored by Rep. Andy Meisner, D-Ferndale—passes and is signed into law, the buyer of Rimanelli’s home would be allowed to retain the current $3,500 tax bill, dodging the pop-up tax—the name given to the adjusted tax amount a new homeowner pays when a just-purchased home is reassessed for taxes based on its full market value.» —“Home-sale accelerant” by Margarita Bauza Detroit Free Press (Michigan) Mar. 25, 20007.
