The Informal Review Process
Step 1
Check your property information on Property.MT.gov
We want to make sure you don’t have any questions about your property.
You can use Property.MT.Gov to view details about your property and review its characteristics, such as:
- Number of bedrooms
- Number of bathrooms, or
- Square footage
Step 2
Get your questions answered by our local staff
You may contact your property assessment field office to talk to an appraiser. We will make every effort to address your concerns and resolve any possible misunderstandings.
If you have no additional concerns, your local county treasurer’s office will use the values reported in your notice to calculate your property tax bill.
Time Sensitive Information! If you disagree with our valuation or need us to correct your property’s characteristics, you will need to fill out the Request for Informal Classification and Appraisal Review (Form AB-26) within 30 days from the date on your classification and appraisal notice. The department will review your request for informal review and if we determine any valuation adjustments are warranted, the adjustments will apply to tax years 2019 and 2020.
If you miss the 30-day deadline in 2019 to submit a Request for Informal Classification and Appraisal Review (Form AB-26), you have until June 1, 2020, to submit the form to the department. Please note: If we determine any valuation adjustments are warranted, the adjustments will apply only to tax year 2020.
Step 3

Before filling out your Request for Informal Classification and Appraisal Review (Form AB-26), be sure to have the following information easily available:

Step 4
Formal Appeals
You can choose to appeal the classification or values shown on your notice directly to your local county tax appeal board (CTAB) rather than using our informal review process. Or, if you disagree with the department’s decision after the informal review process, you may appeal our decision with a county tax appeal board (CTAB) in the county where the property is located.
