Extends the jet fuel sales tax exemption until 2043

HB 3249 extends Missouri's existing tax exemption for jet fuel used by airlines in interstate air travel until 2043, replacing a previous expiration date of 2033. The exemption allows airlines to avoid paying state sales and use taxes on jet fuel, provided they have already paid up to $1.5 million in such taxes during a calendar year. Airlines must provide a written certificate to fuel sellers to claim the exemption and may use a direct payment agreement with the state revenue department to manage tax obligations. This change ensures continued tax relief for airlines operating in Missouri's aviation sector without altering the current $1.5 million annual cap on taxable fuel.
