Even if the requirements explained in the preceding discussions are met, you cannot depreciate the following property.
- Property placed in service and disposed of in the same year. Determining when property is placed in service is explained later.
- Equipment used to build capital improvements. You must add otherwise allowable depreciation on the equipment during the period of construction to the basis of your improvements. See Uniform Capitalization Rules in Pub. 551.
