Both houses of Congress introduced bills in 2009 affecting telecom-related taxes. Under S. 1266 and H.R. 2428, the U.S. Department of Transportation would require some new highway projects to incorporate installation of broadband conduits. S. 1147 would offer tax credits to encourage broadband deployment. H.R. 691 extends a business tax credit for rural phone service. Several bills (S. 71, S. 47, H.R. 3011, H.R. 2203) seek to repeal the excise tax on telephone services, while H.R. 1521 and S. 1192 would end state taxes on mobile phone services.
