Estimating your 2025 property taxes
Beginning in 2025, residential property will have two assessment rates. One assessment rate will be used to calculate local government assessed values and the other rate will calculate school district assessed values. The projected state-wide assessment rates will not be finalized until after October of 2025.

Tax Rate
Late each year county commissioners, city councils, school boards, governing boards of special districts, and other taxing authorities determine the revenue needed and allowed under the law to provide services for the following year.
Each taxing authority calculates a tax rate based on the revenue needed from property tax and the total assessed value of real and personal property located within their boundaries. The tax rate is often expressed as a mill levy. Example from San Juan County:
| Revenue from Property Tax | $1,440,922 | = 0.019641 or 19.641 mills |
| Total Assessed Value | $73,362,974 |
The tax rates of the various taxing authorities, except schools, providing services in your tax area are added together to form the total local government tax rate. The following are examples from 2024:
| San Juan County Tax Rate | 0.019641 |
| Town of Silverton Tax Rate | 0.010560 |
| SW Water Conservation District | 0.000380 |
| Total Local Government Tax Rate | 0.030581 |
