System description

Each fortnight, Inland Revenue uses an encrypted USB stick to send details of current Working for Families Tax Credits (WfFTC) recipients to MSD. The details includes the full name, date of birth, address, and tax file number of the qualifying person and spouse. MSD compares these details with its own WfFTC payment details. 

Where an individual is found in both files and that individual has received two or more WfFTC payments during the same period, MSD sends details about  that individual back to IR to have the Tax Credits from IR cancelled and, if appropriate, to establish a debt for the amounts overpaid.
