Issues involving salvage value and useful life continued to arise, as well as controversy regarding the repair allowance, so Congress enacted IRC § 168 in 1981 (generally effective for property placed in service after December 31, 1980). The Accelerated Cost Recovery System (ACRS) was intended to provide a less complicated method for computing depreciation (known as "cost recovery") by eliminating salvage value and specifying recovery periods for various classes of assets. Depreciation deductions were calculated based on the applicable depreciation methods, recovery periods and placed-in-service conventions outlined in § 168. In contrast to the elective ADR system, ACRS was mandatory and provided only five (later six) recovery periods. ACRS also allowed for a faster write-off of assets than had been allowed under previous rules (e.g., the 40-year life for real property was reduced to either a 15, 18, or 19-year recovery period, as reflected by the 1985 amendments to ACRS).
