This bill amends several existing tax statutes to change how taxes on aircraft fuel are treated. It modifies RCW 82.21.030, RCW 82.23B.020, and RCW 82.23A.020 to require that proceeds from taxes imposed on aircraft fuel (as defined in RCW 82.42.010) be deposited into the aeronautics account created in RCW 82.42.090. It also amends RCW 82.42.090 to specify how moneys collected from aircraft fuel taxes are transmitted and credited, although the exact amended text of that provision is not included in the provided material. The changes are procedural and fiscal: they reallocate existing excise and related tax receipts for aircraft fuel to a designated aeronautics account and add rules about when the applicable tax will be imposed each calendar quarter. Under the bill as excerpted, a tax authorized by the section is imposed for an entire calendar quarter unless either (a) the tax was imposed in the immediately preceding quarter and the most recent quarterly balance exceeds $30,000,000, or (b) the tax was not imposed in the immediately preceding quarter and the most recent quarterly balance exceeds $15,000,000. The Office of Financial Management is required to determine certain account balances within 45 days after each calendar quarter and notify the Departments of Revenue and Ecology per related provisions quoted in the excerpt. No new criminal offenses or changes to penalty language are set out in the provided excerpts; existing collector liability and misappropriation penalties appearing in RCW 82.23B.020 are described but not altered in the material supplied. Important text is missing from the excerpt: the amended language of RCW 82.42.090 is not shown, the remainder of RCW 82.23A.020(4) is cut off, the specific “department” charged with tasks like compiling the petroleum-products list is not named, and the excerpts do not clearly state which account’s “most recent quarterly balance” the $30,000,000 and $15,000,000 thresholds refer to.

If enacted, aircraft fuel taxes and related receipts will be funneled directly into the state aeronautics account and the Office of Financial Management will check that account each quarter; when the account balance is above specified thresholds ($30 million if the tax was collected the prior quarter, $15 million if it was not), the aircraft fuel tax may not be imposed for the following quarter. That creates a new, variable revenue stream for aeronautics that can pause when balances are high, so operators who sell or use aircraft fuel can see the tax and their fuel costs turned on or off quarterly, and terminal operators and other collectors must keep filing and remitting on existing schedules and remain liable if they fail to do so. State agencies gain new responsibilities to transmit and credit those receipts to the aeronautics account, publish lists of petroleum products taxed differently, and run the quarterly balance checks and notifications; the State Treasurer, Department of Revenue, OFM, and Ecology will be directly involved. Key implementation details are missing from the extracted text — notably the full amended language for RCW 82.42.090 and which department is responsible for certain duties — so exact operational practices and timing remain unclear.
