The Minnesota IG257 form is a critical document for insurance companies operating within the cities of Duluth, Minneapolis, and St. Paul. This form, known as the Fire Surcharge Return, is required for reporting fire, lightning, and sprinkler-leakage premiums collected during specific periods. Insurers must complete this form even if no premiums were collected, ensuring compliance with state regulations. The surcharge, set at 2% of the gross premiums, is calculated after deducting any returned premiums. Key components of the form include details such as the insurance company’s name, tax identification numbers, and contact information, as well as sections for calculating the total surcharge due, penalties, and interest if applicable. It is essential to note the due dates for submissions, which vary based on the reporting period, and the requirement for electronic payments for certain tax amounts. Additionally, the form provides options for filing amended returns and indicates the necessity for separate payments for each reporting period. Understanding these aspects is vital for compliance and to avoid penalties that may arise from late submissions or incorrect filings.
