Each business must file annually a Business Tangible Personal Property Return declaring a summary of 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 original cost.

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