“I have commented before – in the DG case and ME –v- HMRC (TC)[2017] UKUT 0227 (AAC) – on the different adjudicatory world which tax credits inhabit under theTax Credits Act 2002 (“TCA”) when compared with the other schemes for social security within Great Britain. Perhaps most notably, the concept of “entitlement” to either working or child tax credit is something that only arises at the end of the tax year for which any award has been made. What is legally in place during the course of the tax year is simply an “award” of tax credit and once made the award may only be changed during the year for which it has been made in certain defined statutory circumstances. This difference of approach is both fundamental and deliberate: see paragraphs 28 and 29 of ZM and AB –v- HMRC (TC)[2013] UKUT 547 (AAC) ; [2014] AACR 17.”
“Fifty-six days later 45 Finally, consider the claimant’s position on26 March 2013 which was 56 days from30 January 2013 (including that date). 46 It can no longer be said that she satisfied the requirements of Case A, B, E or F “for at least one day in the preceding 56 days”. 47 But that does not matter, because Case G does not require that the claimant fell within one of those Cases during one of the preceding 56 days. It only requires that, for one day in that period, she should have been entitled to the disability element by virtue of having satisfied the requirements of Case A, B, E or F at some earlier time. 48 Entitlement under Case G is itself entitlement to the disability element by virtue of having satisfied the requirements of Case A, B, E or F at some earlier time. If the claimant had not satisfied Case A, B, E or F at some earlier time, she would not have satisfied Case G. 49 Therefore, other things being equal, entitlement to the disability element under Case G on any particular day gives rise to entitlement under Case G on the following day and the 55 days after that, and so on indefinitely.”
