AP ENTERPRISE: Federal tax revenues plummeting

"The numbers could hardly be more stark: Tax receipts are on pace to drop 18 percent this year, the biggest single-year decline since the Great Depression, while the federal deficit balloons to a record $1.8 trillion."

"Other figures in an Associated Press analysis underscore the recession's impact: Individual income tax receipts are down 22 percent from a year ago. Corporate income taxes are down 57 percent. Social Security tax receipts could drop for only the second time since 1940, and Medicare taxes are on pace to drop for only the third time ever."
