Where there is a risk that we are currently paying out too much tax credits, we need to take prompt action to revise the award. However, in many situations if we amend the current year award (CY) the tax credit system will automatically amend the previous year award (PY) and that is not lawful unless we have opened an enquiry. You should therefore follow the rules set out below:-
Where you start with an examination and you find out the change(s) also affects the PY you must issue a S19 notice of enquiry for the PY before you amend either the PY or the CY.
