Legislative Session and Lobbying

Citizens Guide: How to Get Involved 

You have the constitutionally-protected right to have your voice heard by your elected officials.

The Constitutions of the United States and of the State of Montana ensure every citizen the right to speak on every public issue and to be heard by officials at every level of government.

The Montana Legislature extends that right to any bill (which includes any resolution). Montana’s Legislature functions in a completely open atmosphere. After full consideration and with comments and advice from the public, every vote by committee and by either house must be a public vote.

To learn more about the current legislative session, the best resource is the Montana Legislative Branch website. At this website, you can find information about the status and substance of a bill, who your legislators are and how to contact them, livestream hearings, and more! 

Lobbying Information

The Commissioner of Political Practices also makes information about lobbying money in Montana publicly available. Any member of the public can see who is registered as a lobbyist, who is a principal (a person or entity that pays lobbyists to lobby on their behalf), and how money is spent to influence legislation and legislators. Lobbying FAQ 

See a list of registered principals and lobbyists for the current legislative session under the adjacent column 'List of Registered Principals and Lobbyists'

To see how money is spent, there are two databases to reference:

One database stores lobbying reports that are submitted digitally via the lobbying database. These digital reports from 2009 - present can be found in the Principal and Lobbyist Online Reporting System. Reports that are filed as paper hardcopies or are emailed or faxed are available (along with digital reports) on our 2009 - present digitized hard copy platform.

Electronic Lobbying Database  

You can also learn more about lobbying in Montana with our Lobbying Frequently Asked Questions (FAQ).

1-Possible reports: After the session, any time $5,000 or more is spent on lobbying activities in a single month, an L-5 must be filed on the 15th of the following month. The report must also retroactively include any previous expenses from months were $5,000 or more was NOT spent. For example, if a principal spends $2,000 in June and $5,000 in July, they must file a monthly L-5 on August 15th. This report would cover all June and July expenses and activity. Please see MCA 5-7-208. If $5,000 is not spent in a single month after the legislative session concludes, an L-5 Year End Session Report is required to be filed by February 15, 2024. All post-session lobbying activity and expenses must be disclosed in this L-5 report. Please see MCA 5-7-208.

2- Required report: February 15, 2024: Year-end Session L-5 report required if any lobbying activity or expenses occurred during the 2023 session or after the 2023 session's adjournment. If a principal terminated their lobbyist by the end of the legislative session, and no other lobbyists are active, this report is not required.   If a principal does not have any lobbying activity after the legislative session and they did not terminate all lobbyists by the end of the session, they must file the L-5 Year End Session Report stating that no activity or expenses occurred. Please see MCA 5-7-208.
