Sec. 451.418.  COLLECTION OF EMISSIONS TAXES BY COUNTY ASSESSOR-COLLECTOR.  (a)  The county assessor-collector of a county in which an authority has territory shall collect the authority's motor vehicle emissions taxes from residents of the authority who reside in that county.
(b)  A resident of an authority shall pay the motor vehicle emissions tax for each motor vehicle owned or controlled by the resident to the county assessor-collector at the time and with whom the resident applies for registration of the resident's motor vehicle for the ensuing registration year.  An applicant for registration shall pay the full amount of the motor vehicle emissions tax for the tax year unless application is made after June 30 of the tax year and the applicant files with the county assessor-collector an affidavit that the vehicle has not for any previous quarter of the tax year been operated in the authority.  The county assessor-collector shall issue to each taxpayer, on payment of the tax, the original motor vehicle emissions tax receipt bearing an identifying number or symbol for the motor vehicle for which the tax is paid.  One copy of the receipt shall be retained by the county assessor-collector.
(c)  A county assessor-collector may not register a motor vehicle subject to an authority's motor vehicle emissions tax until the motor vehicle emissions tax is paid for the tax year or other period that the motor vehicle emissions tax is due.
(d)  The board shall, on or before November 1 of each year, certify to the county assessor-collector of each county having territory in the authority the motor vehicle emissions tax rate for each class of motor vehicles for the succeeding tax year.  The board shall furnish to the county assessor-collector motor vehicle emissions tax receipts in triplicate.
(e)  A county assessor-collector is entitled to a fee of 45 cents for each motor vehicle emissions tax receipt issued by the assessor-collector to be used for paying the expenses incurred in collecting the tax and issuing the tax receipts under this section.
(f)  After deducting the fee authorized by Subsection (e), the county assessor-collector shall, on or before the 15th day of each month, send to the authority all taxes, penalties, and interest collected on behalf of the authority during the preceding calendar month.  The county assessor-collector and the authority may agree to a payment schedule and interval other than the schedule and interval specified by this subsection.
