Ian Liddell-Grainger (Bridgwater and West Somerset, Conservative)
To ask the Chancellor of the Exchequer how many hashes from the payment system have been (a) matched and (b) not matched to real time information (RTI) data from employers since the start of the RTI pilot to date.
David Gauke (Exchequer Secretary, HM Treasury; South West Hertfordshire, Conservative)
The hash matching mechanism, built into the real time information (RTI) system, can only be applied once the RTI alignment process has been completed. Hatch matching will also only be possible where the payments to employees are made using a Bacs service user number.
