(1)(a)(i) In computing the tax imposed under this chapter, a credit is allowed for each person for qualified aerospace product development. For a person who is a manufacturer or processor for hire of commercial airplanes or components of such airplanes, credit may be earned for expenditures occurring after December 1, 2003. For all other persons, credit may be earned only for expenditures occurring after June 30, 2008.

(2) The credit is equal to the amount of qualified aerospace product development expenditures of a person, multiplied by the rate of 1.5 percent.

(3) Except as provided in subsection (1)(b) of this section the credit must be claimed against taxes due for the same calendar year in which the qualified aerospace product development expenditures are incurred. Credit earned on or after July 1, 2005, may not be carried over. The credit for each calendar year may not exceed the amount of tax otherwise due under this chapter for the calendar year.

Finding—2003 2nd sp.s. c 1: "The legislature finds that the people of the state have benefited from the presence of the aerospace industry in Washington state. The aerospace industry provides good wages and benefits for the thousands of engineers, mechanics, and support staff working directly in the industry throughout the state. The suppliers and vendors that support the aerospace industry in turn provide a range of jobs. The legislature declares that it is in the public interest to encourage the continued presence of this industry through the provision of tax incentives. The comprehensive tax incentives in this act address the cost of doing business in Washington state compared to locations in other states." [ 2003 2nd sp.s. c 1 s 1.]
