On Form 4562 Depreciation and Amortization, enter the following text for each method of depreciation:
For 3-, 5-, 7-, or 10-year property eligible for the 200% Declining Balance method, you may make an irrevocable election to use the 150% Declining Balance method. The election applies to all property within the classification that was placed in service during the tax year.
You may make an irrevocable election to use the Straight Line method, instead of the Declining Balance method, for all property within a classification that is placed in service during the tax year.
For 200% Declining Balance and 150% Declining Balance property, the depreciation will switch to the Straight Line method in the first tax year the Straight Line rate exceeds the Declining Balance rate.
