What is the difference between ADR and ACRS in income tax law?
Dear dj: The ADR system was put into law about 1970 and the categories were established for this system. The ACRS system was put on the books in 1981 and complimented the old ADR method of depreciation. My guess is if you look through the two systems some items will be covered by the old ADR system and not by the newer ACRS. Also you may have started depreciating an item under the old ADR and if the life extends to today it would still be covered by the older method. This advice was prepared based on our understanding of the tax law in effect at the time it was written as it applies to the facts that you provided. Click on my profile to read more.
