Effect of Trade-In on Tax Basis

If you trade in some business equipment that was used 100 percent for business, in exchange for new business equipment of the same asset category, the transaction will not be a taxable event because it will be treated as a "like-kind exchange."

However, the basis of the new equipment will be equivalent to the adjusted basis of the old equipment, plus any additional cash you paid for the new equipment. This tax basis represents the maximum amount you can claim as depreciation for the item, for tax purposes.

If you trade in a vehicle that was used partly for business and acquire another vehicle that will be used in your business, you must use the following computation to determine the depreciable tax basis of the replacement vehicle.

The basis for figuring depreciation for the replacement vehicle is:

• the adjusted basis of the old vehicle, plus
• any additional amount paid for the replacement vehicle, minus
• the excess, if any, of the total amount of depreciation that would have been allowable during the years before the trade if 100 percent of the use of the vehicle had been business and investment use, over the total amounts actually allowable as depreciation during those years.
