The U.S. Constitution requires that all bills regarding taxation must originate in the House of Representatives. The Committee of Ways and Means is the chief tax-writing committee of the United States House of Representatives. Members of the Ways and Means Committee are not allowed to serve on any other House Committees unless they apply for a waiver from their party's congressional leadership. The Committee has jurisdiction over all taxation, tariffs, and other revenue-raising measures, as well as a number of other programs including:
Social Security Unemployment insurance Medicare Enforcement of child support laws Temporary Assistance for Needy Families Foster care and adoption programs
