Personal Property Tax Calculator
Calculate annual Ad Valorem taxes for vehicles, boats, and business equipment. Includes depreciation schedules for 27+ US states and asset classes.
About
In many jurisdictions, specifically within the United States, movable assets such as automobiles, watercraft, and heavy machinery are subject to annual personal property taxes. Unlike fixed registration fees, these "Ad Valorem" taxes are based on the current market value of the asset, which degrades over time. Accurate estimation requires applying specific depreciation curves to the original purchase price before multiplying by the local levy rate.
This calculator addresses the complexity of estimating future liabilities for depreciating assets. It incorporates standard depreciation schedules for common asset classes (5-year MACRS for IT equipment, linear degradation for vehicles) and applies state-specific average tax rates. Owners of luxury vehicles, RVs, or business fleets use this data to forecast the total cost of ownership over the asset's lifecycle.
Formulas
The tax liability decreases annually as the asset depreciates. The calculation logic is:
Where DepreciationFactor is retrieved from a declining balance schedule based on the asset class.
