Levy of tax - Interest

Beginning on and after July 1, 1984, there shall be levied an excise tax of three and one-fourth percent (3 1/4%) of the purchase price of each aircraft that is to be registered with the Federal Aviation Administration, upon the transfer of legal ownership of any such aircraft or the use of any such aircraft within this state.
The excise tax levied pursuant to the provisions of Sections 6001 through 6004 of this title is in lieu of all other taxes on the transfer or the first registration in this state on aircraft, including optional equipment and accessories attached thereto at the time of sale and sold as a part thereof, except annual aircraft registration fees. The tax hereby levied shall be due at the time of the transfer of legal ownership or first registration in this state, and shall be collected by Service Oklahoma at the time of the issuance of a certificate of registration for any such aircraft.
The excise tax levied pursuant to the provisions of this section shall be delinquent from and after the twentieth day after the legal ownership or possession of any aircraft is obtained. Any person failing or refusing to pay the tax provided for in this section on or before the date of delinquency shall pay, in addition to the tax, a penalty of ten percent (10%) on the total amount of tax due.
Interest shall be collected on the total delinquent tax at the rate of one and one-fourth percent (1 1/4%) per month from the date of the delinquency until the tax is paid.
