Yes, it will be necessary to call Tax Credit Office to inform them of your actual figures - and this needs to done by 31st January.
Although your tax credits would continue if the January deadline is not met, the amount you receive from 6th April may not be accurate. This could mean that you have been overpaid and result in you having to pay back at a later date, with the possibility of also receiving a penalty.
If you require any help with your accounts, tax return or Tax Credits, please feel free to contact your local TaxAssist Accountants office.
