Lobbyist Registration, Filing and Audit Information

What Type of Lobbyist Am I?

A Client Lobbyist is the party paying for lobbying services on its behalf. In other words, the client lobbyist is expending or agreeing to expend the threshold amount of $3,000 in a calendar year.

A Communicator Lobbyist receives payment and does the actual lobbying legwork (i.e., communicating). A Communicator Lobbyist receives or agrees to receive $3,000 for lobbying activities in a calendar year. Communicator Lobbyists can take different forms:

  • Individual
  • Member of a Business Organization (e.g., a firm or association that employs a number of communicator lobbyists)
  • In-house Communicator (a lobbyist who is a salaried employee of a Client Lobbyist)

Graphic explaining the Lobbyist Identifier. It shows that a client lobbyist pays to promote interests, while a communicator lobbyist is paid to lobby. Examples include administrative, legislative, inside, and outside lobbying.

Lobbyist Audit Corner

The Office of State Ethics is required to annually audit registration and disclosure reports of lobbyists to promote accountability for lobbyists’ activities. Our random selection of lobbyists is performed periodically by our staff in a public meeting under the observation of the Citizen’s Ethics Advisory Board.

The primary purpose of the audit is to determine whether information reported to the Office of State Ethics is timely, accurate and complete.

Audit Benefits:

  • Ensure compliance with the Code of Ethics
  • Identify potential risks and liabilities and to improve legal compliance
  • Provide a systemic evaluation to determine effectiveness and to improve organizational performance
  • Serve the public interest and confidence in our government

The Office of State Ethics recommends that lobbyists maintain their documentation in accordance with our Procedures Manual for Lobbyist Recordkeeping and Audit.

Education and Training:

-Training Presentations-

-Guides to the Code of Ethics for Lobbyists-
