Yesterday, the Senate passed a compromise version of the American Jobs Creation Act of 2004 (HR 4520) which, when signed into law by President Bush, will extend, by one year, bonus depreciation enacted in 2003. The law extends the placed-in-service requirement. As a result, businesses acquiring assets that require a significant lead time from manufacture to delivery, such as aircraft,will have an additional year to order aircraft, take delivery and place them in service. A copy of the conference report for HR 4520 as passed by the Senate is available here.
