Why is midnight, April 15, the deadline for all income tax returns?

Remember the waits for state driver's licenses and vehicle plates when every driver was required to get them by the same date. Then someone proposed renewing licenses in the month of the driver's birthday and plates in the month of the vehicle's original purchase.Why can't that be done for income tax returns? Congress and the Internal Revenue Service have made April 15 into National Trauma Day. . . .

The U.S. Postal Service is overloaded, and overtime must be paid to handle the crush of last-minute returns. Then, too, because of the single deadline, the IRS has hired thousands of temporary workers, many of whom are giving faulty answers to taxpayers. . . .

April 15 is a day dreaded by millions of people in this country. It should not be. It would not be if the IRS and Congress would figure out how to divide the taxpayers by 12 and make it a year-round operation.
