The state portion of sales tax on clothes and shoes disappeared Saturday, at least on clothes or shoes that cost less than $110. Coming a year after the city removed its portion of the tax, clothes are shoes are now entirely sales tax-free in New York City. Yippee! To celebrate, we thought we'd go out and buy ourselves what we've really been needing: a fancy new cell phone. Until we realized there'd still be tax on that, because it's not clothes or shoes. Then we thought maybe we'd get something else we could really use: a good pair of jeans. Until we realized good jeans wouldn't be cheap enough to go untaxed, either. How to celebrate, then? Finally it hit us. We needed new socks. Celebratory, sales tax-free socks. Woo-hoo.
