Commentary: This programme is to be replaced in 2013 by a new information sharing system authorised by section 81BA of the Tax Administration Act 1994. MSD expects that the new process will increase the likelihood of all student entitlements being paid correctly. In preparation for the new information sharing system with IR, the last match data received for this programme was in April.

System description

This programme and the IR/MSD Commencement Cessation Benefit Programme are authorised under the same statutory authority but operate separately, partly because of different administrative processes for students and beneficiaries.

Each month, MSD sends IR, by secure online transfer, details about a selection (approximately 5,000 records) of MSD student clients that have been paid an allowance within a specified study period. Each record provided to IR includes the surname, first initial, date of birth, IRD number and MSD client number, and student allowance date information.

IR matches the MSD information in a two-stage process. The first stage, called ‘Individual Validation', identifies whether IR holds information about the individual. To do this, IR firstly confirms the existence and validity of the IRD number provided by MSD. IR then matches against the date of birth or surname and first initial provided by MSD. The Individual Validation process must be successful for the information comparison process to take place.

The second stage called ‘Information Comparison' checks if there is an overlap between the period the individual was in receipt of any allowance payments and any periods during which the individual was in receipt of other gross income.

For the matched records, IR returns to MSD the employee's full name, date of birth, MSD and IRD identifiers, employer's name, address, email and phone contact details, employment commencement and cessation dates and monthly gross income amount.

MSD checks its records to determine whether there is an explanation for the apparent discrepancy. If there is not, the individual is sent a notice of adverse action (s.103 notice).
