This depends on how you view the regs.
[b:26e84d7725]HBR06 32[/b:26e84d7725] sets a deeming provision as to how Tax Credits [u:26e84d7725]shall[/u:26e84d7725] be calculated. On the face of it, this would appear to suggest that there is nothing that can be done to retrospectively amend Tax Credits previously paid.
However, if I was the clmt, I’d take issue with the words “[b:26e84d7725]due to be paid[/b:26e84d7725]” (amongst other things). If the amount DUE to be paid is retrospectively found to be zero, I’m wondering if it can be argued that Tax Credits should be reassessed accordingly (for HB). Even if that is correct, do the DAR regs then allow a supersession (or revision) re the beneficial change rules?
As an aside, the removal of a clmt’s Tax Credits suggests there has been a change in earnings / other income – this will need to be looked at. Ironically, if there has been another change of income that causes an overpayment, I think it can be argued that the underlying entitlement rules REQUIRE that the reduced / nil Tax Credit must be taken into account – the wording of HBR 104 requires that the correct circumstances must be taken into account as if they were known at the time…..
Hope this helps.
