Barcode Automation for Revenue Collection to Organize Disbursement and Enhance Efficiency Act or the BARCODE Efficiency Act This bill requires federal tax returns that are prepared electronically, but printed and filed on paper, to bear a code that when scanned converts the data in such return to an electronic format. It also requires the Internal Revenue Service (IRS) to use optical character recognition technology to transcribe returns and correspondence that are not prepared electronically and are printed on paper. The IRS may decline to use such technology if it determines that it is slower or less reliable than manual transcription.
