The information below shows you how to phone or write to HMRC. Contact them if you need help managing or renewing your tax credits online or by phone.
GENERAL ENQUIRIES: There are several ways of contacting HMRC about your tax credits.
You may also find some new security procedures in place if you contact the tax credits helpline telephone number.
HMRC tax credit helpline uses the 'ID Authentication Service' security system. IDAS checks the identity of all claimants who contact the helpline telephone number.
This process applies to callers for general enquiries, disputes, and anyone requesting claim forms.
Issues can arise on matters where claimants report particular changes to their circumstances. They sometimes have disputes about incorrect advice given to them. The best policy is to keep evidence of your contact with the specific office or tax credit department.
You can phone the Tax Credits Office for general enquiries, to request a claim form, or to inform HMRC about changes to your circumstances. You can also get face to face or hotline advice if you have special needs.
