Two owners of Regional Scaffolding — a company that has made tens of millions of dollars off state and city contracts, including at the now-demolished Deutsche Bank building — were charged today in Manhattan with filing a false 2007 tax return.

According to the complaint against them, Paul Mazzucca, 39, and Lawrence Blinn, Jr., 47, under-reported the company’s income and fudged paperwork to cover for paying workers less than union wages and failing to withhold the appropriate taxes.

They face anywhere from probation up to four years prison if convicted of a single count each of first degree offering a false instrument for filing.
