What is the standard depreciation rate for a motor vehicle?

There is no "standard" depreciation rate for a motor vehicle, as it can vary depending on several factors such as the type of vehicle, its original cost, and the depreciation method used. In the United States, for example, the Internal Revenue Service (IRS) allows businesses to depreciate passenger cars and light trucks over a period of 5 years using the modified accelerated cost recovery system (MACRS). However, heavy vehicles such as buses and semi-trucks may have different depreciation rates. Additionally, individual jurisdictions may have different regulations governing depreciation of motor vehicles. It is therefore recommended to consult with a tax professional or refer to specific guidelines provided by relevant accounting standards or regulations to determine the appropriate depreciation rate for a particular motor vehicle.
