1. The director of the department of economic development may, subject to the requirements of section 536.021, issue such rules and regulations as he deems necessary regarding the qualifications necessary for an area to be deemed an “enterprise zone” and for the continuation of such designation. Beginning January 1, 1987, the director shall prescribe the method for submitting applications for claiming the tax credits allowed in sections 135.225 and 135.235 and the exemption allowed in section 135.220 and shall, if such application is approved, certify same to the director of revenue that the taxpayer claiming the credits allowed in sections 135.225 and 135.235 and the exemption allowed in section 135.220 has satisfied all requirements prescribed in sections 135.200 to 135.255, and is therefore eligible to claim the credits and exemption. The director shall also calculate and specify the amount of the credits earned by the taxpayer during the taxpayer’s first taxable year in which such credits are claimed and for each of the nine succeeding taxable years the credits are claimed by the taxpayer and shall certify such amounts to the director of revenue. The director shall certify the extent to which such earned credits and the exemption allowed in section 135.220 can be claimed to the director of revenue and shall notify the taxpayer in writing of such determination. The director may prescribe such rules and regulations necessary to carry out the provisions of sections 135.200 to 135.255.

2. The director of revenue shall determine the amount of the taxpayer’s refund, as allowed in section 135.245, if any, and shall notify the taxpayer in writing of any amount to be refunded. The director of revenue may, subject to the requirements of section 536.021, prescribe rules and regulations necessary to process the credits allowed in sections 135.225 and 135.235 and the exemption allowed in section 135.220 and the refund allowed in section 135.245 following certification of eligibility by the director. No rule or portion of a rule promulgated under the authority of this section shall become effective unless it has been promulgated pursuant to the provisions of section 536.024.

3. Any taxpayer who has submitted an application for claiming tax credits as allowed in sections 135.225, 135.235, or the exemption allowed in section 135.220 or an application to be certified as a new business facility for the purpose of claiming the refund as allowed in section 135.245, may file with the director of economic development, a protest within sixty days (one hundred fifty days if the taxpayer is outside the United States) after the date of such certification notice or the date of the notice denying such certification. The protest shall be in writing and shall set forth the grounds on which the protest is based.

4. If a protest is filed, the director of economic development shall consider the taxpayer’s grounds for protest and make a determination concerning such protest. The director of economic development shall notify the taxpayer in writing of such determination within thirty days following the date in which the written protest was received. Such notice shall be mailed to the taxpayer by certified or registered mail and such notice shall set forth briefly the director of economic development’s findings of fact and the basis of decision.

5. The decision of the director of economic development on the taxpayer’s protest is final upon the expiration of thirty days from the date when he mails notice of his action to the taxpayer unless within this period, the taxpayer seeks review of the director of economic development’s determination by the administrative hearing commission.
