Which of the following properties is not subject to taxation?

Federal property is not subject to taxation because the U.S. Constitution establishes that the federal government cannot impose taxes on itself to ensure that it can operate without interference from state and local governments. This principle is rooted in the idea of maintaining a separation between different levels of government. Since federal properties, such as military bases, national parks, and federal buildings, are owned by the federal government, they are exempt from state and local taxation in order to preserve the integrity and functionality of federal operations.

In contrast, private property, commercial property, and ownership property are typically subject to various forms of taxation at both the state and local level. These categories of property contribute to the tax base that helps fund essential services within communities, making them liable for property taxes, sales taxes, and other levies enacted by state or local authorities.
