Each business must file a Business Tangible Personal Property Return annually, summarizing property cost values by purchase year. Generally, an item is assessed at 85% percent of its original cost in the year acquired; thereafter, the percentage decreases by 10% percent increments. After eight years, the item's assessed value remains constant at 10% percent of the original cost.

Computer equipment and peripherals are valued at 50% of the cost in the first year, 35% in the second year, 20% in the third year, 10% in the fourth year, and 5% in the fifth and all subsequent years.

Businesses located in any of the towns within Prince William County (Dumfries, Haymarket, Occoquan, and Quantico) are subject to the same business tangible personal property tax as all other businesses located in the County. They must file an annual Business Tangible Personal Property Return with the county (click here for an explanation of the requirement).
