Claims - requests: Welsh language claims

Version 1.0

Changes to previous version - amended guidance. Replaces ‘Claim form in Welsh language (Info) and (AG)’.


The Welsh Language Act 1993 established that we should treat the Welsh and English languages on an equal basis within Wales.

In March 2008, HMRC agreed and signed a four-year arrangement called the ‘Welsh Language Scheme’.

In accordance with this Act, some customers may make ask for a tax credits claim form (TC600) in the Welsh Language.

If you receive such a request, either in writing or during a phone conversation, you should

  • obtain the necessary information from the customer
  • pass the details to the Welsh Service Provider.

The Welsh Contact Centre will then issue the claim form to the customer in the Welsh Language.


Note: When sending customer, staff or process data to another individual or team, make sure you follow the latest data security guidelines or contact the Data Guardian or Data Security Team for advice.
