Making Work Pay credit: The bulk of the individual tax cuts - more than $139 billion worth goes to this credit that Obama campaigned on. The credit, worth up to $500 per worker, essentially would offset some of the Social Security payroll taxes that Americans pay this year and next. Employers would still have to kick in their share. Under the House version, you could choose to receive the credit through your paycheck or wait to claim it on your tax return, said Mark Luscombe, principal analyst with CCH Inc., an Illinois provider of tax information. The House plan is more generous. It would more gradually phase out the credit, starting once adjusted gross income exceeded $75,000 for singles or $150,000 for married joint filers. The Senate would start phasing it out after income topped $70,000 for individuals and $140,000 for joint filers.
