That was money lost to the U.S. Postal Service, which is in financial crisis driven partly by the shift to e-mail and electronic commerce.The Postal Service recouped about half of that amount because the IRS used postcards to notify taxpayers of the change. But as the report notes, that was a one-time expense. And the report doesn’t attempt to quantify what the Postal Service will lose from the additional taxpayers who go with the IRS’ advice to “e-file” their annual returns.   Tags: IRS.
