Economic Stimulus Package: Starting in May, the Treasury will begin sending economic stimulus payments to more than 130 million households. To receive a payment, taxpayers must have a valid Social Security number, $3,000 of income and file a 2007 federal tax return. IRS will take care of the rest. Eligible people will receive up to $600 ($1,200 for married couples), and parents will receive an additional $300 for each eligible child younger than 17. Millions of retirees, disabled veterans and low-wage workers who usually are exempt from filing a tax return must do so this year in order to receive a stimulus payment.
