LINCOLN, Neb. (AP) — Nebraska’s secretary of state is once again warning the public about a mailing that seeks $150 from businesses before they file their biennial reports with the state.

Secretary of State John Gale said Monday that the documents provided by the company are not necessary to file with his office. Gale says the mailers have surfaced again because many nonprofits and limited liability companies are preparing to file their reports.

The mailing comes from a group calling itself the Nebraska Council for Corporations.

Gale says notices from his office are easily recognizable. They contain his name and title, the image of Nebraska’s state seal and contact information for the state’s Business Services Division.

Gale says anyone with questions or concerns can contact the Nebraska attorney general’s office.
