Washington Revised Code Title 60. Liens § 60.28.051. Duties of disbursing officer upon completion of contract

Upon completion of a contract, the state, county, or other municipal officer charged with the duty of disbursing or authorizing disbursement or payment of such contracts shall forthwith notify the department of revenue, the employment security department, and the department of labor and industries of the completion of contracts over thirty-five thousand dollars. Such officer shall not make any payment from the retained percentage fund or release any retained percentage escrow account to any person, until he or she has received from the department of revenue, the employment security department, and the department of labor and industries certificates that all taxes, increases, and penalties due from the contractor, and all taxes due and to become due with respect to such contract have been paid in full or that they are, in each department's opinion, readily collectible without recourse to the state's lien on the retained percentage.
