Personal property tax is deductible if it is a state or local tax that is:
Charged on personal property.
Based only on the value of the personal property.
Charged on a yearly basis, even if it is collected more than once a year, or less than once a year.
A tax that meets the above requirements can be considered charged on personal property even if it is for the exercise of a privilege. For example, a yearly tax based on value qualifies as a personal property tax even if it is called a registration fee and is for the privilege of registering motor vehicles or using them on the highways.
