The notoriously slow Congress passed the $787 billion economic stimulus package in a matter of weeks. President Barack Obama signed it into law less than one month into his presidency. So, just how soon will Americans start reaping the benefits of tax cuts in it? By April 1, according to the president. “Never before in our history has a tax cut taken effect faster or gone to so many hardworking Americans,” Obama said Saturday in his weekly radio and Internet address. He said the Treasury Department has begun directing employers to reduce the amount of taxes withheld from people's paychecks in accordance with the new law, and that in six weeks, a typical family will start taking home at least $65 more every month. Obama says his signature “Making Work Pay” tax break will affect 95 percent of working families. The $400 credit for individuals is to be doled out through the rest of the year. Couples are slated to get up to $800. Most workers are to see about a $13 per week increase in their take-home pay. In 2010, the credit would be about $7.70 a week, if it is spread over the entire year. People who do not earn enough money to owe income taxes are eligible for the credit, an attempt to offset the payroll taxes they pay. Obama's expensive and ambitious package of federal spending and tax cuts is designed to revive the economy and save or create 3.5 million or more jobs. It will inject a sudden boost of cash into transportation, education, energy and health care, while aiming to help recession victims through tax cuts, extended unemployment benefits and short-term health insurance assistance. It also will add to a rapidly growing national debt. The president signed the measure into law Tuesday. In his weekly address, Obama said he was grateful to Congress, governors, mayors and everyday people who supported the measure. Still, he added: “It is only a first step on the road to economic recovery. And we cannot fail to complete the journey.” He said the country also must stem foreclosures, repair the banking system, get credit flowing again and revamp financial industry regulations.
