Book excerpt: The U.S. Master Depreciation Guide offers tax and accounting professionals who work with businesses a one-stop resource for guidance in understanding and applying the complex depreciation rules to their fixed assets. This area is especially challenging, because bits and pieces of applicable information must be gathered from a maze of Revenue Procedures, IRS Tables, and IRS Regulations. These sources are frequently old and include some materials that may no longer be applicable. The U.S. Master Depreciation Guide pulls the pieces together, so practitioners can make sense of all the corresponding information and put the information into practice.
