Motor Fuel Tax
E-Filing: Forms OP-216 and O-MF

5/5 stars for client support

Connecticut DRS requires fuel tax filers to submit applicable schedule detail through myconneCT using a predefined CSV layout. If the data is incomplete, inconsistent, or formatted incorrectly, filing becomes last-minute rework.


IGEN generates validated e-file returns and predefined CSV schedules in the format myConneCT requires.

IGEN Supports:

  • Form OP-216: Special Fuel Tax Return
  • Form O-MF: Motor Vehicle Fuels Tax Return
  • Schedule MF-R: Schedule of Receipts
  • Schedule MF-D: Schedule of Disbursements

The Challenge

Many Connecticut fuel tax teams still prepare filing data manually. That often means:

  • Rebuilding CSV files each month from inconsistent templates
  • Managing schedule data across multiple spreadsheets
  • Copying data between systems without a validation step
  • Catching formatting errors after the filing deadline has arrived

The risk is not completing the return. The risk is whether the schedule data is clean, standardized, and ready for upload when it needs to be.
