(a) An insurer may credit a contingent surcharge amount on its next remission to the association if the insurer has already remitted the amount to the association for:      
        (1) the portion of the surcharge the insurer was not able to collect from the policyholder, if the policy was canceled or expired;       
        (2) the portion of the surcharge remitted to the association, or deposited directly in the premium surcharge trust fund, that was later refunded to the policyholder as a result of a rescission, midterm cancellation, or midterm policy change, as described in §5.4184 of this division (relating to Application of Premium Surcharges); or       
        (3) the portion of a surcharge remitted to the association, or deposited directly in the premium surcharge trust fund or funds, in excess of a deposit premium as described in §5.4184 of this division.       
      (b) An agent may not offset payment of a contingent surcharge or an association surcharge to the insurer for any reason; however, a surplus lines agent allowed by an affiliated surplus lines insurer to remit contingent surcharges to the association on its behalf under §5.4186(a) of this division (relating to Remittance of Contingent Surcharges), may offset as provided in this section.
