Mission Statement

The Montana Taxpayers Action Group exists to ensure transparency and responsibility in how tax burdens are imposed and how public resources are expended.

We educate, assist, and advocate for taxpaying citizens of Montana. When taxes are increased, we identify the responsible parties.

Protest Form

The button below is a downloadable Protest Form for paying property taxes, and an AB-26 form for a review of property tax assessments. The “Reason for Protest” on the Tax Payment form for most of our members will be “participating in a class action suit.” The cause numbers for the two class action suits are DV-18-60 and DV-18-113. You will want to include BOTH cause numbers on the Protest Form.
