Every vendor, on or before the last day of the month following each calendar quarterly period of three months, shall file with the director of revenue a return of all taxes collected for the preceding quarter in the form prescribed by the director of revenue, showing the total sales price of the tangible personal property sold by the vendor, the storage, use or consumption of which is subject to the tax levied by this law, and other information the director of revenue deems necessary. The return shall be accompanied by a remittance of the amount of the tax required to be collected by the vendor during the period covered by the return. Returns shall be signed by the vendor or the vendor's authorized agent. The director of revenue may promulgate rules or regulations changing the filing and payment requirements of vendors, but shall not require any vendor to file and pay more frequently than required in this section.  2. Where the aggregate amount of tax required to be collected by a vendor is in excess of two hundred and fifty dollars for either the first or second month of a calendar quarter, the vendor shall pay such aggregate amount for such months to the director of revenue by the twentieth day of the succeeding month. The amount so paid shall be allowed as a credit against the liability shown on the vendor's quarterly return required by this section.  3. Where the aggregate amount of tax required to be collected by a vendor is less than forty-five dollars in a calendar quarter, the director of revenue shall by regulation permit the vendor to file a return for a calendar year. The return shall be filed and the taxes paid on or before January thirty-first of the succeeding year.  4. Except as provided in subsection 5 of this section, every person purchasing tangible personal property, the storage, use or consumption of which is subject to the tax levied by sections 144.600 to 144.748, who has not paid the tax due to a vendor registered in accordance with the provisions of section 144.650, shall file with the director of revenue a return for the preceding reporting period in the form and manner that the director of revenue prescribes, showing the total sales price of the tangible property purchased during the preceding reporting period and any other information that the director of revenue deems necessary for the proper administration of sections 144.600 to 144.748. The return shall be accompanied by a remittance of the amount of the tax required by sections 144.600 to 144.748 to be paid by the person. Returns shall be signed by the person liable for the tax or such person's duly authorized agent. For purposes of this subsection, the reporting period shall be determined by the director of revenue and may be a calendar quarter or a calendar year. Annual returns and payments required by the director pursuant to this subsection shall be due on or before April fifteenth of the year for the preceding calendar year and quarterly returns and payments shall be due on or before the last day of the month following each calendar period of three months. Upon the taxpayer's request, the director may allow the filing of such returns and payments on a monthly basis. If a taxpayer elects to file a monthly return and payment, such return and payment shall be due on or before the twentieth day of the succeeding month.  5. Any person purchasing tangible personal property subject to the taxes imposed by sections 144.600 to 144.748 shall not be required to file a use tax return with the director of revenue if such purchases on which such taxes were not paid do not exceed in the aggregate two thousand dollars in any calendar year.  6. Nothing in subsection 5 of this section shall relieve a vendor of liability to collect the tax imposed pursuant to sections 144.600 to 144.748 on the total gross receipts of all sales of tangible personal property used, stored or consumed in this state and to remit all taxes collected to the director of revenue in accordance with the provisions of this section nor shall it relieve a purchaser from paying such taxes to a vendor registered in accordance with the provisions of section 144.650. ­­-------- (L. 1959 H.B. 35 § 9, A.L. 1969 p. 255, A.L. 1983 1st Ex.
