Congressional Salaries. As of 2012, the annual salary for any congressman, from first-term representatives to the most senior members -- except those holding leadership positions -- was set at $174,000. This was the compensation level set as of January 1, 2009, and frozen by law in the intervening years.
The salary for most members of the U.S. House of Representatives is $174,000 per year, according to the Congressional Research Service. This annual wage is the same for members of both the House of Representatives and the Senate. Salaries are higher for those in leadership roles. In particular, the Speaker of the House receives $223,500 per year, and the majority and minority leaders of the House each earn $193,400 per year. Congress established those salary levels in 2009 and agreed to keep them frozen through at least 2012.
