Tingle Table: An 18-bin table used by the U.S. Internal Revenue Service to sort paper tax returns. The table was named after James Tingle, the IRS employee who invented it in 1961. (UPDATE: See the comments on the Double-Tongued Dictionary entry for some Tingle family history.)
Tomorrow is the deadline for filing tax returns in the United States. (It was extended by two days because the traditional filing date, April 15, fell on a Sunday, and April 16 is Emancipation Day, a legal holiday in the District of Columbia.) Last year, 73 million returns were filed online, 20 million of them from home computers. So far this filing season, almost 72 percent of all returns have been e-filed, up almost 6 percent from last year. But you can't e-file directly to the IRS, which has declined to set up a portal. According to National Public Radio, Intuit--maker of the popular TurboTax software--lobbied hard to keep it that way. Intuit is one of several companies that collect a fee for each e-filed return.
