A Democrat-friendly national nonprofit is requesting state officials investigate Republican Sen. Dean Heller’s lack of a business license for his alfalfa hay farm.

The American Democracy Legal Fund, which was founded by Democratic operative David Brock, filed the complaint against Heller with Secretary of State Barbara Cegavske’s office on Feb. 23, alleging the Republican senator received more than $200,000 in income from the farm without registering for a state business license until 2018.

The complaint comes in the wake of a February story by the Reno Gazette-Journal detailing that Heller had never received a business license or requested an exemption for his 120-acre hay farm in rural Smith Valley since purchasing it in 2010.

The complaint alleges that Heller began earning income on the sale of hay in 2011, yet neither submitted the $200 registration fee required of almost all entities to do business in Nevada nor submitted forms requesting an exemption from paying the fee. Heller’s office told the newspaper that the farm had never turned a profit, but that he had requested a sole proprietorship license in February to go the extra mile, even though he “wasn’t required to do so.”

“Nevadans deserve to know if their senator has been cheating the system, and Senator Heller needs to pay the fines he owes for breaking the law he helped enforce on others for a decade,” ADLF head Brad Woodhouse said in a statement.

Using information from his financial disclosure, the complaint alleged that in at least four years of operating the farm, Heller reported income higher than the threshold of income requiring him to register as a Nevada business.

According to the Nevada secretary of state’s office, 11,252 entities in the state have requested an exemption from paying a state business license fee, including 8,409 home-based businesses and 1,454 nonprofits.

The American Democracy Legal Fund, which filed the complaint, was founded in 2014 as a 527 organization (groups that do not “expressly advocate” for a candidate or party) that primarily files legal challenges against Republican office-holders nationwide.
