About Property Taxes in Oregon

Oregon's property tax system is one of the most complex in the country due to Measure 50 (1997), which created two separate values for every property: the Real Market Value (RMV) and the Maximum Assessed Value (MAV). The MAV can increase only 3% per year, while the RMV fluctuates with the market. Property is taxed on the lesser of these two values — for most properties, the MAV is lower and therefore controls the tax bill. This system means long-term property owners are often taxed on values far below current market prices. However, when a property is sold or significantly improved, the MAV resets closer to the new market value.
