For a $1 million property with $200,000 in fixtures, the average annual tax bill would be approximately $21,060. Property tax rates in U.S. cities spanned a wide spectrum, dropping below 1% in some locations and reaching up to 4% elsewhere.
Effective tax rates are often higher for commercial, industrial and apartment buildings than for homes, due to classification systems used in many states. In select jurisdictions, business properties are sometimes taxed at rates multiple times those levied on residential properties; for example, Charleston’s business tax rate can be about sixfold higher than its residential rate.
