(1) Except as provided in subsection (2) of this section and RCW 82.32.534, taxes deferred under this chapter need not be repaid.

(2)(a) If, on the basis of the tax performance report under RCW 82.32.534 or other information, the department finds that an investment project is used for purposes other than qualified research and development or pilot scale manufacturing at any time during the calendar year in which the investment project is certified by the department as having been operationally completed, or at any time during any of the seven succeeding calendar years, a portion of deferred taxes is immediately due according to the following schedule:

Year in which use occurs	% of deferred taxes due
1	100%
2	87.5%
3	75%
4	62.5%
5	50%

(b) If the economic benefits of the deferral are passed to a lessee as provided in RCW 82.63.010(7), the lessee is responsible for payment to the extent the lessee has received the economic benefit.

(3)(a) Notwithstanding subsection (2) of this section, in the case of an investment project consisting of multiple qualified buildings, the lessee is solely liable for payment of any deferred tax determined by the department to be due and payable under this section beginning on the date the department certifies that the project is operationally complete.
