Do not panic, citizens: If the government shuts down, the IRS will still be there to serve you

Many federal Web sites will go dark if the government shuts down tomorrow night, the White House indicated this afternoon.

A 16-page memo (PDF) to federal agencies says their Web sites may stay online only in a small number of situations, including tax collection and handling "exempted" activities such as payments and other functions that are paid for by previous annual budgets.

"The mere benefit of continued access by the public to information about the agency's activities would not warrant the retention of personnel or the obligation of funds to maintain, or update, the agency's Web site" during a shutdown, says the memo, prepared by the White House's Office of Management and Budget.
