Today, Treasury and the IRS issued final regulations (TD 9754) that authorize the disclosure of certain items of return information to the Bureau of the Census (Bureau) in conformance with section 6103(j)(1).  According to the preamble, such return information will be used by the Bureau “for purposes of structuring a census that costs less per housing unit and still maintains high quality results.”  The regulations finalize temporary regulations that were made pursuant to a request from the Secretary of Commerce and are effective February 26.
