House Republicans are moving to pass a one-year extension of temporary tax breaks affecting millions of businesses and individuals. Most of the more than 50 tax breaks expired at the end of 2013, so the extension would only run through the end of the month. However, it would allow taxpayers to claim the tax breaks when they file their 2014 tax returns. (AP Photo/Susan Walsh, File)
