Property taxes fall into two categories, Secured and Unsecured. A Secured property tax is a tax for a physical property, most often real estate and land. An Unsecured property tax is for personal items, like an airplane, boat, or business.
Depending on the location you live, property taxes are paid annually or semi annually. If Secured property taxes are not paid, the property will be foreclosed on to cover the taxes owed. If Unsecured taxes are not paid, the item can be seized and sold to cover the taxes owed.
