Ad valorem (personal property) taxes are levied by the jurisdiction for the right to use property within the jurisdiction.  There are several key terms related to ad valorem taxes:

Lien date – The date that the location of the property is determined for ad valorem tax purposes.

Report Due Date - The date the ad valorem return is due at the assessor’s office.

Payment Due Date – The date the tax becomes due.

Most personal tangible property items may be subject to ad valorem tax, however, there are differences between states.  The lien date for many states is 12/31, while in Alabama its 10/1.  The report due date for the majority of states is between 2/15 – 4/15; however, the Alabama report due date is 12/31.  Other differences include the taxability of specific items, such as inventory, software, supplies and work-in-process.  States also vary in the special exemptions available.  As a general rule, if a company has personal property in a state on the lien date, there may be an ad valorem reporting requirement.

The Mechanics of the Ad Valorem Process
Once it is determined that a business has an ad valorem return filing requirement, the personal property should be categorized by class, based on the classification categories for the state in which the property is located and by year.  For example, there may be a category for furniture and fixtures, and another for equipment.  When the property has all been placed in the correct categories, the base for the tax is the original cost, multiplied by an assessment percentage.  Alabama uses composite tables in determining the assessment value of the property.  The cost of the property is multiplied by the composite rate based on the class and year of purchase.  It should be noted that in most states, the property assessment value will never reach zero, no matter how long something is owned.
