Tax Credits Helpline and Opening Hours

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.

Contacting HM Revenue and Customs: 3 Helpful Tips

Keep notes of any telephone conversations and meetings with personnel at HMRC. Being able to confirm dates, times and contact names, along with a brief note of the discussion, is useful.
Consider sending any letters by recorded delivery. That means staff at HMRC will sign for acceptance of the letter. You can also ask the Post Office for proof of postage and always keep a copy of any letters and enclosures you send.
Set up a file where you keep all copies of notices, letter, and tax credit forms. This is a good place to add details used to fill out claim forms and how you made any relevant calculations.
