NIH has published the information regarding the salary limitation for NIH grant and cooperative agreement awards and extramural research and development contract awards for Fiscal Year 2010.

"Every year since 1990 Congress has legislatively mandated a provision limiting the direct salary that an individual may receive under an NIH grant.  For FY 2010, Public Law 111-117: Consolidated Appropriations Act, 2010 restricts the amount of direct salary to Executive Level I of the Federal Executive Pay scale. The Executive Level I annual salary rate was $196,700 for the period January 1 through December 31, 2009.  Effective January 1, 2010, the Executive Level I salary level increased to $199,700."
