Hi James,
The old form and the new form don’t ask for the pension type as a person is entitled to a rebate if they hold a Pensioner Concession Card irrespective of what type of payment eg Single parent, age, disability etc. If you need to know what type of payment they are on, the Centrelink verification search shows this information under the “payment type” and you can therefore get the information from there and record it if required.
The consent forms stipulate that “payment type” will be provided to councils so there are no barriers to recording the information as long as the information is stored and used for the purpose it is provided, being to determine their eligibility for a rebate.
Kind regards,
Matthew.
