Development of Software for Defined Benefit Funds

The supplementary instructions for reporting the ‘Defined benefit contributions’ in the
2013-14 MCS are now available. These instructions supplement the MCS electronic reporting specification version 10.

The regulations for calculating and reporting the ‘defined benefit contributions’ in the member contribution statements (MCS) for the 2013-14 and later years were made on 15 May 2014.

All defined benefit funds and their administrators are required to:

  • Lodge all 2013-14 MCS by the due date 31 October 2014.
  • If you have calculated the amount of the ‘Defined benefit contributions’ using the new regulations and have prepared the MCS based on that on time to lodge by the due date then lodge the MCS with this field completed,
  • If not, then you must zero fill the ‘Defined benefit contributions’ field (6.121 in the specification) and lodge the MCS by 31 October 2014 and then amend the MCS by no later than 31 January 2015 to provide this data in accordance with the regulations.
