Conversions/Vehicle Adaptions

"Conversion" is defined as the modification of the vehicle in such manner that it no longer retains all of the characteristics of the vehicle category under which it is certified for type approval purposes.

A new process of assessment is required when vehicle conversions have taken place. Revenue requires a Vehicle Owner’s Declaration of Conversion (form VRTCONV), supported by a Suitably Qualified Individual Declaration of Conversion (template VRTCONVSQI), only in the following circumstances - where the Vehicle Registration Certificate at J1 (VRT vehicle category) shows ‘B’ or ‘C’ or ‘D’ or is blank and:

  • change of EU Vehicle Category, and/or
  • increase in the number of seats, and/or
  • change in the number of seatbelt fittings, and/or
  • change of EU Bodywork

A person wishing to obtain motor tax for a previously registered vehicle, provided one or more of the above limited circumstances apply, must comply with the Revenue VRT procedures in relation to conversions, ie the vehicle must be certified by a Suitably Qualified Individual (SQI) as to the quality of the conversion and the accuracy of the declaration. The owner declaration on Revenue form VRTCONV stamped by the SQI and an accompanying declaration by the SQI on headed paper should be posted to the Revenue Commissioners, Central Vehicle Office, Rosslare Harbour, Co. Wexford, where the conversion will be assessed to determine if additional VRT is due.

The forms can be downloaded from http://www.revenue.ie

Post assessment the Central Vehicle Office will return a copy of the VRTCONV form to the applicant, stamped to indicate it has been assessed along with a Confirmation of Assessment following Declaration of Conversion Form.  Both these forms should be included in the motor tax application to tax the converted vehicle.
