Averages for commercial property tax rates across 53 major U.S. cities reached 1.76% in 2024, according to a study from the Lincoln Institute of Land Policy. That report found a property valued at $1 million, plus $200,000 in fixtures, typically resulted in a $21,060 annual tax bill. The study noted rates varied significantly, with some cities below 1% and others as high as 4%.
Classified assessment systems in several states may lead to higher effective tax rates on commercial, industrial, and apartment buildings compared to residential properties. In some locations, businesses pay rates multiple times higher than homeowners, such as in Charleston, where the commercial rate can be approximately six times greater.
