How it works
Property in Douglas County is first assigned a real market value (RMV). Under Oregon’s Measure 50 system, taxable assessed value (AV) is generally the lesser of RMV or maximum assessed value (MAV), with MAV increases capped by law. Local taxing districts apply their rates to AV to calculate property tax. The resulting tax is then tested against Measure 5 constitutional limits, which cap education and general government taxes based on RMV. If those limits are exceeded, taxes are reduced through a process known as compression.
Examples
An estimate begins with the property’s assessed value and applies the combined rates of the county, school district, city, and any special districts that serve the property’s tax code area. If the calculated tax exceeds Measure 5 limits when compared to real market value, the tax is reduced to comply with constitutional caps.
