Attention Foreign Risk Retention Groups—RE: Payment of Premium Taxes

  2. Montana no longer requires a copy of an Examination Report certified by the insurance regulatory official of the state in which the examination was conducted, if a hard copy is filed with the state of domicile and if the report is filed electronically with the NAIC.

Attention Premium Tax Filers: Please be aware that our office no longer sends a yearly overpayment confirmation letter to each premium tax filer. A letter will only be sent to you if we disagree with the amount of overpayment available to carry forward that you report on your return. If you do not receive a letter, please refer to your prior-year tax records to determine the amount of prior-year overpayment to claim on your return.
