(1) Provided the taxpayer fulfills the requirements of this section, all qualified personal property owned by a taxpayer is exempt from property taxes levied for any state purpose.

The claim must be made upon forms as prescribed and furnished by the department. The application must indicate if the taxpayer is applying for a 10 or 15-year exemption.

(b) If a taxpayer is assessed under chapter 84.12 RCW, a claim for an exemption under this section from taxes payable the following year must be filed by March 31st with the department together with the annual report required under RCW 84.12.230 and a statement attesting that the taxpayer meets the requirements of subsection (3) of this section. The claim must be made upon forms as prescribed and furnished by the department. The application must indicate if the taxpayer is applying for a 10 or 15-year exemption.

(c) The taxpayer claiming an exemption under this subsection (2) and paying the production excise tax under RCW 82.96.010 must file an annual attestation in the manner and form prescribed by the department.

(3) The taxpayer must register with the department to pay the production excise tax authorized in RCW 82.96.010.

(5) The department must apportion personal property assessed under chapter 84.12 RCW that is granted an exemption under this section pursuant to RCW 84.12.360.

(6)(a) If a taxpayer fails to meet the annual attestation requirement in subsection (2)(c) of this section or fails to pay the production excise tax required in RCW 82.96.010, the department shall send a notice to the taxpayer to comply or forfeit the exemption. The taxpayer must come into compliance within 60 days from the date of the notice.
