Effective - 28 Aug 1982   148.380. Returns, assessment of tax, procedure — notice to company — taxes, how paid — suspension of delinquents — disposition of money. — 1. Every such company, on or before the first day of March in each year, shall make a return verified by the affidavit of its president and secretary, or other chief officers, to the director of the department of commerce and insurance, stating the amount of all direct premiums received by it from policyholders in this state, whether in cash or in notes, during the year ending on the thirty-first day of December, next preceding. Upon receipt of such returns the director of the department of commerce and insurance shall verify the same and certify the amount of the tax due from the various companies on the basis and* at the rate provided in section 148.370, taking into consideration deductions and credits allowed by law, and shall certify the same to the director of revenue together with the amount of the quarterly installments to be made as provided in subsection 2 of this section, on or before the thirtieth day of April of each year.  2. Beginning January 1, 1983, the amount of the tax due for that calendar year and each succeeding calendar year thereafter shall be paid in four approximately equal estimated quarterly installments, and a fifth reconciling installment. The first four installments shall be based upon the tax for the immediately** preceding taxable year ending on the thirty-first day of December, next preceding. The quarterly installments shall be made on the first day of March, the first day of June, the first day of September and the first day of December. Immediately after receiving certification from the director of the department of commerce and insurance of the amount of tax due from the various companies, the director of revenue shall notify and assess each company the amount of taxes on its premiums for the calendar year ending on the thirty-first day of December, next preceding. The director of revenue shall also notify and assess each company the amount of the estimated quarterly installments to be made for the calendar year. If the amount of the actual tax due for any year exceeds the total of the installments made for such year, the balance of the tax due shall be paid on the first day of June of the year following, together with the regular quarterly payment due at that time. If the total amount of the tax actually due is less than the total amount of the installments actually paid, the amount by which the amount paid exceeds the amount due shall be credited against the tax for the following year and deducted from the quarterly installment otherwise due on the first day of June. If the March first quarterly installment made by a company is less than the amount assessed by the director of revenue, the difference will be due on June first, but no interest will accrue to the state on the difference unless the amount paid by the company is less than eighty percent of one-fourth of the total amount of tax assessed by the director of revenue for the immediately preceding taxable year.  3. If the estimated quarterly tax installments are not so paid, the director of revenue shall notify the director of the department of commerce and insurance who shall thereupon suspend such delinquent company from the further transaction of business in this state until such taxes shall be paid, and such companies shall be subject to the provisions of sections 148.410 to 148.461.  4. Upon receipt of the money the state treasurer shall receipt one-half thereof into the general revenue fund of the state, and one-half thereof to the credit of the county foreign insurance fund for the purposes set forth in section 148.360. ­­-------- (L. 1945 p. 993 § 6098b, A.L. 1945 p. 1013, A. 1949 S.B. 1031, A.L. 1982 S.B. 470)  *Word "and" does not appear in original rolls.  **Word "immediate" appears in original rolls.
