The 61-year-old owner of an Omaha concrete and construction business has been indicted on federal charges of filing false tax returns for 2006 and 2007.

The U.S. Attorney’s office in Omaha said in a news release Wednesday that John Main, of Omaha, is charged in a two-count indictment.

The first count says Main filed an income tax return for 2006 claiming Main Concrete and Construction’s gross sales were more than $765,000. Federal prosecutors say it was nearly $1.37 million.

The second county says Main’s income tax return for 2007 claimed sales of nearly $535,000. Prosecutors say sales for that year were actually more than $925,000.

If convicted, Main faces up to three years in federal prison on each count.

Main declined to comment when reached on Wednesday
