WTC is being replaced by Universal Credit (UC)–so no NEW claims unless:
If a WTC cannot be made, then an application could be considered for:
Universal Credit (UC) – a means-tested credit paid to those of working age on low income either in or out of work –elements payable for children, child care, carers, those fit or unfit for work and with rent to pay. For more, read our Guide to Universal Credit.
From 27th January 2021 (the closing of the Severe Disability Premium ‘Gateway’), no new claims can be made for Working Tax Credit, on the basis of receiving the Severe Disability Premium (SDP).
