The tax is equal to the maximum allowable federal credit under the internal revenue code for estate, inheritance, legacy, and succession taxes paid to the states. This tax shall be reduced by the amount of all estate, inheritance, legacy, and succession taxes paid to states other than Michigan, which amount shall not exceed an amount equal to the proportional share of that maximum allowable federal credit that the gross value of all real and tangible personal property located in states other than this state bears to the gross value of all property included in the decedent's gross estate wherever located.
