Pay property taxes online 

Please Note the Following Important Tax Information:

  • Delinquent tax information is located on the right-hand side of your bill. The 2001 Montana Legislature passed a law that requires the tax bill to indicate that a tax lien certificate or an assignment of the tax lien has been issued on the property. If this notation appears on your bill, you should contact the Treasurer’s office for information.
  • The Tax Payer Number (formerly known as SUID number), which can be located in top right hand corner, should be referred to when making your payment. It is also very helpful to have this number when requesting information by phone.
  • It is important to send in the correct half of the stubs (1st or 2nd half) when mailing your payments. The barcode on the stub helps us post your payment accurately and quickly.
  • On the left side of the bill there will be a short explanation if you received low income assistance or veteran's exemption.

Helpful Information:

  • Missoula County collects taxes for many jurisdictions it has no authority over, including the City, School Districts, Fire Districts, and other service districts. If you have a specific question regarding your tax bill, it’s important for you to call the appropriate jurisdiction for answers to your questions.
  • Our office hours are 8 a.m. to 5 p.m. The Tax Office also processes Motor Vehicle renewals; you may experience long lines the last week of November and May. You may avoid the lines by mailing your payment or by paying online.
  • Mail must be post-marked on or before the due date to avoid penalty & interest costs. Please note that tax payments made toward the end of May and November may take up to two weeks to be posted due to the high volume of payments received.

    Mail payment to:

    Missoula County Treasurer
    200 W Broadway
    Missoula, MT 59802

  • The Department of Revenue – Assessment and Appraisal Offices have moved to 2681 Palmer Suite I, they are no longer located within the County Courthouse – contact them with valuation questions at 329-1400.

Property Taxes

Your property taxes can be paid online by using Webpay, our online Property Tax Payment system.  You will need to use your tax identification (TaxID) number or you can search for the owner name.   Payments for Real Estate may be made as follows:

Current taxes may be paid; or if delinquent taxes exist for the current year they may also be paid online.  If you owe delinquent taxes for prior years, you will need to come into the office or call to get the correct amount owed as penalty and interest accrue daily.

Payments for Mobile Home or Personal Property taxes may be made online for current or any delinquent taxes.

There will be certain times throughout the year that we will temporarily shut down Webpay for administrative purposes.  A notice will be placed on the home page of Webpay during those times.
