A. A foreign or alien insurer which is subject to the tax imposed by Section 624 of this title shall be entitled to a credit against said tax actually paid to and placed in the General Revenue Fund of the state, not including any of said tax monies placed in pension funds and not including any of said tax monies placed in escrow, if, during the year for which the tax is being assessed, the insurer or its affiliate maintained a regional home office in this state in a building owned or leased by the insurer. To receive a credit against the tax imposed for the year in which the regional home office was established, said office must have been maintained continuously from on or before August 1 of that year through the last day of the calendar year. For succeeding years, an insurer or its affiliate shall have maintained the regional home office continuously from the first day of the calendar year for which the tax is imposed through the last day of that calendar year. The Home Office Credit shall be calculated as follows: 1. Until June 30, 2010, the credit shall be equal to the following percentages of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted: a. fifteen percent (15%), if there are more than two hundred full-time, year-round Oklahoma employees, but less than three hundred full-time, year-round Oklahoma employees, b. twenty-five percent (25%), if there are more than three hundred full-time, year-round Oklahoma employees, but less than four hundred full-time, year- round Oklahoma employees, c. thirty-five percent (35%), if there are more than four hundred full-time, year-round Oklahoma employees, but less than five hundred full-time, year-round Oklahoma employees, or d. fifty percent (50%), if there are five hundred or more full-time, year-round Oklahoma employees; and 2. Beginning July 1, 2010, in the calculation of the credit, the amount to be apportioned to the Oklahoma Firefighters Pension and Retirement Fund, the Oklahoma Police Pension and Retirement System and the Law Enforcement Retirement Fund shall be applied prior to the calculation of the credit. The amount of the credit shall be derived from amounts remaining after the apportionment to the Oklahoma Firefighters Pension and Retirement Fund, the Oklahoma Police Pension and Retirement System and the Law Enforcement Retirement Fund. The credit shall be calculated by first applying a “Home Office Credit Allotment Rate” of forty-seven percent (47%) to the gross premium tax owed by the insurer and then determining the allowable credit by applying the following percentages of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted: a. fifteen percent (15%), if there are more than two hundred full-time, year-round Oklahoma employees, but less than three hundred full-time, year-round Oklahoma employees, b. twenty-five percent (25%), if there are more than three hundred full-time, year-round Oklahoma employees, but less than four hundred full-time, year- round Oklahoma employees, c. thirty-five percent (35%), if there are more than four hundred full-time, year-round Oklahoma employees, but less than five hundred full-time, year-round Oklahoma employees, or d. fifty percent (50%), if there are five hundred or more full-time, year-round Oklahoma employees.

To receive a credit against the tax imposed for the year in which the home office was established, said office must have been maintained continuously from on or before August 1 of that year through the last day of the calendar year. For succeeding years, an insurer shall have maintained the home office continuously from the first day of the calendar year for which the tax is imposed through the last day of that calendar year. Insurers who take action before August 1, 2000, to establish their home office in this state shall be entitled to a credit against the tax imposed on or after January 1, 2001, which shall be in addition to the credit the insurer is entitled to for that year. The Home Office Credit shall be calculated as follows: 1. Until June 30, 2010, the credit shall be equal to the following percentages of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted: a. thirty-five percent (35%), if there are more than four hundred full-time, year-round Oklahoma employees, but less than five hundred full-time, year-round Oklahoma employees, or b. fifty percent (50%), if there are five hundred or more full-time, year-round Oklahoma employees; and 2. Beginning July 1, 2010, in the calculation of the credit, the amount to be apportioned to the Oklahoma Firefighters Pension and Retirement Fund, the Oklahoma Police Pension and Retirement System and the Law Enforcement Retirement Fund shall be applied prior to the calculation of the credit. The amount of the credit shall be derived from amounts remaining after the apportionment to the Oklahoma Firefighters Pension and Retirement Fund, the Oklahoma Police Pension and Retirement System and the Law Enforcement Retirement Fund. The credit shall be calculated by first applying a “Home Office Credit Allotment Rate” of forty-seven percent (47%) to the gross premium tax owed by the insurer and then determining the allowable credit by applying the following percentages of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted: a. thirty-five percent (35%), if there are more than four hundred full-time, year-round Oklahoma employees, but less than five hundred full-time, year-round Oklahoma employees, or b. fifty percent (50%), if there are five hundred or more full-time, year-round Oklahoma employees. C. A domestic insurer which is subject to the tax imposed by Section 624 of this title shall be entitled to a credit against said tax actually paid to and placed in the General Revenue Fund of the state, not including any of said tax monies placed in pension funds and not including any of said tax monies placed in escrow, if, during the year for which the tax is being assessed, the insurer maintained a regional home office in at least five or more counties in this state in buildings owned or leased by the insurer. To receive a credit against the tax imposed for the year in which the regional home offices were established, said offices must have been maintained continuously from on or before August 1 of that year through the last day of the calendar year. For succeeding years, an insurer shall have maintained the regional home offices continuously from the first day of the calendar year for which the tax is imposed through the last day of that calendar year. The Home Office Credit shall be calculated as follows: 1. Until June 30, 2010, the credit shall be equal to the percentage of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted as established in subsection A of this section; and 2.

The credit shall be calculated by first applying a “Home Office Credit Allotment Rate” of forty-seven percent (47%) to the gross premium tax owed by the insurer and then determining the allowable credit by applying the percentage of the amount due after the credits authorized by Sections 624.1 and 625 of this title have been deducted as established in subsection A of this section.
