(1) As provided in this section, every bill enacting a new tax preference must include a tax preference performance statement, unless the legislation enacting the new tax preference contains an explicit exemption from the requirements of this section.

(2) A tax preference performance statement must state the legislative purpose for the new tax preference. The tax preference performance statement must indicate one or more of the following general categories, by reference to the applicable category specified in this subsection, as the legislative purpose of the new tax preference:

(a) Tax preferences intended to induce certain designated behavior by taxpayers;

(b) Tax preferences intended to improve industry competitiveness;

(c) Tax preferences intended to create or retain jobs;

(d) Tax preferences intended to reduce structural inefficiencies in the tax structure;

(e) Tax preferences intended to provide tax relief for certain businesses or individuals; or

(f) A general purpose not identified in (a) through (e) of this subsection.

(3) In addition to identifying the general legislative purpose of the tax preference under subsection (2) of this section, the tax preference performance statement must provide additional detailed information regarding the legislative purpose of the new tax preference.

(4) A new tax preference performance statement must specify clear, relevant, and ascertainable metrics and data requirements that allow the joint legislative audit and review committee and the legislature to measure the effectiveness of the new tax preference in achieving the purpose designated under subsection (2) of this section.

(5) If the tax preference performance statement for a new tax preference indicates a legislative purpose described in subsection (2)(b) or (c) of this section, any taxpayer claiming the new tax preference must file an annual tax performance report in accordance with RCW 82.32.534.

(6)(a) Taxpayers claiming a new tax preference must report the amount of the tax preference claimed by the taxpayer to the department as otherwise required by statute or determined by the department as part of the taxpayer's regular tax reporting responsibilities. For new tax preferences allowing certain types of gross income of the business to be excluded from business and occupation or public utility taxation, the tax return must explicitly report the amount of the exclusion, regardless of whether it is structured as an exemption or deduction, if the taxpayer is otherwise required to report taxes to the department on a monthly or quarterly basis. For a new sales and use tax exemption, the total purchase price or value of the exempt product or service subject to the exemption claimed by the buyer must be reported on an addendum to the buyer's tax return if the buyer is otherwise required to report taxes to the department on a monthly or quarterly basis and the buyer is required to submit an exemption certificate, or similar document, to the seller.

(b) This subsection does not apply to:

(i) Property tax exemptions;

(ii) Tax preferences required by constitutional law;

(iii) Tax preferences for which the tax benefit to the taxpayer is less than one thousand dollars per calendar year; or

(iv) Taxpayers who are annual filers.

(c) The department may waive the filing requirements of this subsection for taxpayers who are not required to file electronically any return or report under this chapter.

(7)(a) Except as otherwise provided in this subsection, the amount claimed by a taxpayer for any new tax preference is subject to public disclosure and is not considered confidential tax information under RCW 82.32.330, if the reporting periods subject to disclosure ended at least twenty-four months prior to the date of disclosure and the taxpayer is required to report the amount of the tax preference claimed by the taxpayer to the department under subsection (6) of this section.

(b)(i) The department may waive the public disclosure requirement under (a) of this subsection (7) for good cause. Good cause may be demonstrated by a reasonable showing of economic harm to a taxpayer if the information specified under this subsection is disclosed. The waiver under this subsection (7)(b)(i) only applies to the new tax preferences provided in chapter 13, Laws of 2013 2nd sp. sess.

(ii) The amount of the tax preference claimed by a taxpayer during a calendar year is confidential under RCW 82.32.330 and may not be disclosed under this subsection if the amount for the calendar year is less than ten thousand dollars.

(c) In lieu of the disclosure and waiver requirements under this subsection, the requirements under RCW 82.32.534 apply to any tax preference that requires a tax performance report.

(8) If a new tax preference does not include the information required under subsections (2) through (4) of this section, the joint legislative audit and review committee is not required to perform a tax preference review under chapter 43.136 RCW, and it is legislatively presumed that it is the intent of the legislature to allow the new tax preference to expire upon its scheduled expiration date.

(9) For the purposes of this section, "tax preference" and "new tax preference" have the same meaning as provided in RCW 82.32.805.

(10) The provisions of this section do not apply to the extent that legislation creating a new tax preference provides an exemption, in whole or in part, from this section, whether or not such exemption is codified.
