2017 Real Property Classification and Appraisal Notice
Gallatin County Real Property owners will receive the
"2017 Real Property Classification and Appraisal Notice"
from Montana Department of Revenue in June 2017
The purpose of a classification and appraisal notice is to inform property owners and purchasers under contract for deed of the market and taxable value of their property for property tax purposes. Study it carefully. If the classification and appraisal notice reflects a value with which you disagree, or if you have any questions concerning the value or property characteristics, call your local Department of Revenue office immediately.  Gallatin County Local Department of Revenue Office can be reached at (406) 582-3400.  Do not wait until you receive your tax bill if you have questions about your property value. By then, the deadline to either informally object to the Department of Revenue or formally appeal to your local county tax appeal board has passed.
The following formulas are used to determine general property tax:
Market/Productivity Value x Tax Rate = Taxable Value
Taxable Value x Mill Levy = General Property Tax (exclusive of local fees and assessments)
Taxpayers have the right to request the Montana Department of Revenue conduct an informal classification and appraisal review (Form AB-26) and/or file a formal appeal at the county and state level at any time but only once each appraisal cycle.

Gallatin County Treasurer's Office Information:
-  Gallatin County Treasurer's Office sends out delinquent notices as follows:
-  Real Property, delinquent notices are sent twice a year - January and late July.  It is not beneficial to the taxpayers or Treasurer's Office to send out delinquent notices when there are companies that want to purchase delinquent taxes from the County that send out thousands of notices to taxpayers in early July.  This is why the Treasurer's Office waits until late July to send out our delinquent notices.
-  Mobile Homes, delinquent notices are sent twice a year - January and July;
-  Personal Property, delinquent notices are sent once a year - August.
-  Gallatin County Treasurer's Office has started a list of taxpayers email addresses so we can send a reminder to the taxpayer when their taxes are due.  By law, the Treasurer's Office sends one (1) tax bill for Real Estate the end of October each year with two (2) stubs due November 30th and the following May 31st, for Mobile Home the end of April each year with two (2) stubs due May 31st and November 30th, and for Personal Property the end of May each year with one (1) stub due June 30th.  On the back of your stubs is a line to write your email address so we can add to our list.  You may call or email the Treasurer's Office with your email address also.  The Treasurer's Office doesn't sell the email list as it is for our information only.
-  By law, the Treasurer's Office can't post partial real estate tax payments.  If your  payment is received after the due date and penalty & interest is not included, we will return your payment back to you with a notice providing the total amount due and additional time to return the tax payment with penalty and interest to our office.
