Support the Mobile Workforce State Income Tax Simplification Act

The Mobile Workforce State Income Tax Simplification Act has companion bills pending in both chambers of Congress. S. 1645 was introduced on November 5, 2013 by lead sponsors Senator Sherrod Brown (D-OH) and Senator John Thune (R-SD), and has been referred to the Senate Finance Committee of which both lead sponsors are members. The companion House bill, H.R. 1129, was previously introduced on March 13, 2013 by long-time supporters Rep. Howard Coble (R-NC) and Rep. Hank Johnson (D-GA), and referred to the House Judiciary Committee, where both lead sponsors have been veteran members. By direction of the Chairman, H.R. 1129 was heard in the House Judiciary Committee’s Subcommittee on Regulatory Reform, Commercial and Antitrust Law on April 29, 2014.
