“From June 12 through August 17, 2012, the Texas Comptroller of Public Accounts will waive penalties and interest for businesses that file delinquent tax reports and pay all taxes due, or amend reports that under-reported taxes and pay the taxes due. Reports originally due before April 1, 2012, are eligible for this limited amnesty. The amnesty is available for all state and local taxes and fees administered by the Comptroller's office, with the exception of Public Utility Commission gross receipts assessments. Sports and community venue tax and property taxes are not administered by the Comptroller and are not eligible. The Unclaimed Property program is not a part of tax amnesty.”
