(c) "Tax information" means (i) a taxpayer's identity, (ii) the nature, source, or amount of the taxpayer's income, payments, receipts, deductions, exemptions, credits, assets, liabilities, net worth, tax liability deficiencies, overassessments, or tax payments, whether taken from the taxpayer's books and records or any other source, (iii) whether the taxpayer's return was, is being, or will be examined or subject to other investigation or processing, (iv) a part of a written determination that is not designated as a precedent and disclosed pursuant to RCW 82.32.410, or a background file document relating to a written determination, and (v) other data received by, recorded by, prepared by, furnished to, or collected by the department of revenue with respect to the determination of the existence, or possible existence, of liability, or the amount thereof, of a person under the laws of this state for a tax, penalty, interest, fine, forfeiture, or other imposition, or offense. However, data, material, or documents that do not disclose information related to a specific or identifiable taxpayer do not constitute tax information under this section. Except as provided by RCW 82.32.410, nothing in this chapter requires any person possessing data, material, or documents made confidential and privileged by this section to delete information from such data, material, or documents so as to permit its disclosure;

(d) "State agency" means every Washington state office, department, division, bureau, board, commission, or other state agency;

(e) "Taxpayer identity" means the taxpayer's name, address, telephone number, registration number, or any combination thereof, or any other information disclosing the identity of the taxpayer; and

(f) "Department" means the department of revenue or its officer, agent, employee, or representative.

(2) Returns and tax information are confidential and privileged, and except as authorized by this section, neither the department of revenue nor any other person may disclose any return or tax information.

(3) This section does not prohibit the department of revenue from:

(a) Disclosing such return or tax information in a civil or criminal judicial proceeding or an administrative proceeding:

(i) In respect of any tax imposed under the laws of this state if the taxpayer or its officer or other person liable under this title or chapter 83.100 RCW is a party in the proceeding;

However, tax information not received from the taxpayer must not be so disclosed if the director determines that such disclosure would compromise any investigation or litigation by any federal, state, or local government agency in connection with the civil or criminal liability of the taxpayer or another person, or that such disclosure would identify a confidential informant, or that such disclosure is contrary to any agreement entered into by the department that provides for the reciprocal exchange of information with other government agencies which agreement requires confidentiality with respect to such information unless such information is required to be disclosed to the taxpayer by the order of any court;

(c) Disclosing the name of a taxpayer against whom a warrant under RCW 82.32.210 has been either issued or filed and remains outstanding for a period of at least ten working days.

(4)(a) The department may disclose return or taxpayer information to a person under investigation or during any court or administrative proceeding against a person under investigation as provided in this subsection (4). The disclosure must be in connection with the department's official duties relating to an audit, collection activity, or a civil or criminal investigation. The disclosure may occur only when the person under investigation and the person in possession of data, materials, or documents are parties to the return or tax information to be disclosed. The department may disclose return or tax information such as invoices, contracts, bills, statements, resale or exemption certificates, or checks. However, the department may not disclose general ledgers, sales or cash receipt journals, check registers, accounts receivable/payable ledgers, general journals, financial statements, expert's workpapers, income tax returns, state tax returns, tax return workpapers, or other similar data, materials, or documents.

(b) Before disclosure of any tax return or tax information under this subsection (4), the department must, through written correspondence, inform the person in possession of the data, materials, or documents to be disclosed. The correspondence must clearly identify the data, materials, or documents to be disclosed.

(i) The data, materials, or documents sought for disclosure are cumulative or duplicative, or are obtainable from some other source that is more convenient, less burdensome, or less expensive;

(ii) The production of the data, materials, or documents sought would be unduly burdensome or expensive, taking into account the needs of the department, the amount in controversy, limitations on the petitioner's resources, and the importance of the issues at stake; or

(iii) The data, materials, or documents sought for disclosure contain trade secret information that, if disclosed, could harm the petitioner.

(d) The department must reimburse reasonable expenses for the production of data, materials, or documents incurred by the person in possession of the data, materials, or documents to be disclosed.

(e) Requesting information under (b) of this subsection that may indicate that a taxpayer is under investigation does not constitute a disclosure of tax return or tax information under this section.

(5) Service of a subpoena issued under RCW 82.32.117 does not constitute a disclosure of return or tax information under this section. Notwithstanding anything else to the contrary in this section, a person served with a subpoena under RCW 82.32.117 may disclose the existence or content of the subpoena to that person's legal counsel.

(6) Any person acquiring knowledge of any return or tax information in the course of his or her employment with the department of revenue and any person acquiring knowledge of any return or tax information as provided under subsection (3) (e), (f), (g), (h), (i), (m), (v), and (w) of this section, who discloses any such return or tax information to another person not entitled to knowledge of such return or tax information under the provisions of this section, is guilty of a misdemeanor.
