We can only process your claim once all documentation has been received.
This is because when you receive a tax credits award it is not final until after the end of the tax year for which it has been given.
You can also challenge a decision not to backdate Carer's Allowance if your request is refused.
Carer's Allowance is paid into a bank or building society account either weekly in advance or every four weeks.
Backdating more than 31 days/1 month There are two situations in which it is possible to get backdating of more than 31days/1 month: Refugee status If a person has claimed asylum as a refugee and is then awarded refugee status, providing they apply for tax credits within one month of receiving notification of that refugee status, they will be treated as if they made their tax credits claim from the original date they claimed asylum.
Prior to 6 April 2012, refugees had 3 months from being awarded refugee status to inform HMRC and receive longer backdating.
