(1) The provisions of this chapter do not apply in respect to the use by an eligible farmer of:
(a) Replacement parts for qualifying farm machinery and equipment;
(b) Labor and services rendered in respect to the installing of replacement parts; and
(c) Labor and services rendered in respect to the repairing of qualifying farm machinery and equipment, provided that during the course of repairing no tangible personal property is installed, incorporated, or placed in, or becomes a component of, the qualifying farm machinery and equipment other than replacement parts.
(2)(a) Notwithstanding anything to the contrary in this chapter, if a single transaction involves services that are not exempt under this section and services that would be exempt under this section if provided separately, the exemptions provided in subsection (1)(b) and (c) of this section apply if: (i) The seller makes a separately itemized charge for labor and services described in subsection (1)(b) or (c) of this section; and (ii) the separately itemized charge does not exceed the seller's usual and customary charge for such services.
(b) If the requirements in (a)(i) and (ii) of this subsection (2) are met, the exemption provided in subsection (1)(b) or (c) of this section applies to the separately itemized charge for labor and services described in subsection (1)(b) or (c) of this section.
(3) The definitions and recordkeeping requirements in RCW
82.08.855 apply to this section.
(4) If a person is an eligible farmer as defined in RCW
82.08.855(4)(b)(iv) who cannot prove income because the person is new to farming or newly returned to farming, the exemption under this section will apply only if one of the conditions in RCW
82.08.855(3)(b)(i) (A) or (B) is met. If neither of those conditions are met, any taxes for which an exemption under this section was claimed and interest on such taxes must be paid. Amounts due under this subsection shall be in accordance with RCW
82.08.855(3)(b)(ii).
(5) Except as provided in subsection (4) of this section, the department may not assess the tax imposed under this chapter against a person who no longer qualifies as an eligible farmer with respect to the use of any articles or services exempt under subsection (1) of this section, if the person was an eligible farmer when the person first put the articles or services to use in this state.
