Stopping Tax Credits - change of circumstances - In Year finalisation - reply required (info)


Customers who do not qualify for an automatic In Year finalisation are required to reply to an Award Declaration. This is known as reply required.

These customers will be issued with an

  • award Review form (TC603UR)


  • award Declaration form (TC603UD)

A reply is required to form TC603UD by the In Year Specified Date (IYSD). This reply is also known as the In Year S17 Declaration.

Form TC603UD must be completed with the appropriate income or Taxable Social Security Benefits or IS/JSA/PC. If a change of circumstances needs reporting, the customer must complete the appropriate Statement of Circumstances (SOC) box.

If a reply to form TC603UD is not received by IYSD, the computer will automatically finalise on the information held.

For further guidance, use TCM0338120.
