A bill to amend the Internal Revenue Code of 1986 to provide a temporary payroll increase tax credit for certain employers.

Summary: Small Business Job Creation Tax Act of 2010 - Amends the Internal Revenue Code to allow employers a credit against payroll tax liability for a payroll increase in a quarter over a corresponding quarter in the previous calendar year. Sets the amount of such credit at 20% of such increase for employers that employ fewer than 100 employees and 15% for employers that employ 100 or more employees in any quarter. Limits the total credit amount available for all quarters to $500,000.

Directs the Commissioner of Internal Revenue to: (1) notify all employers required to withhold employment taxes of the enactment and applicability of this Act; and (2) report to Congress on enforcement measures taken to prevent and penalize fraud related to the payroll credit allowed by this Act.
