Changes - miscellaneous (A-F): Capture correction (Info)

A correction to a claim is where an amendment to the original details is needed which will take effect from the original start date. Follow the relevant Changes guidance.

Note: A change of customer’s address is always treated as a correction to ensure that any computer output is issued to the correct address. Before changing an address, ensure that you have the full address including the postcode. If the address has changed to a non-UK address, follow the guidance in TCM0048060.

Always select the correction option

  • where the date the change occurred is over one month old and the customer has previously notified the change


  • where the change relates to Previous Year (PY) and the customer’s Annual Declaration has been finalised.

Always ensure that a change is matched to the correct customer before processing the new information.

If you are taken to the Select Application screen, this will mean that there is more than one claim for this customer. For example, cases where a family break-up has occurred and the customer has re-applied. Where the Select Application screen is displayed, you must select the claims affected by the correction. You will then be taken to the Applicant Details screen where you can continue to process the correction.

If the change affects more than one claim, you must apply the change to each claim affected by the change. However, do not apply changes to previously mismatched claims.

In the case of a joint claim, you must check whether the change applies to one customer or both customers.

Always check the History window first to check for overlapping periods prior to making any change.

You may be notified of these changes in a number of ways. Follow the guidance in TCM0044120.

The function you use to record details of the correction depends on the status of the claim. If the claim is

  • pre-award, you use Function CAPTURE APPLICATION
  • post award, you use Function AMEND APPLICATION.

If you are unable to process the request with the information available, you must contact the customer to obtain the missing information or to clarify the situation.

For example, if it is a joint claim and only the customer has signed a change of address make sure that it applies to both customers.

If you are checking a claim to check what frequency the Child Tax Credit (CTC) is being paid, and the computer does not show the frequency, then the frequency is always four-weekly.

If you are notified of a correction relating to income, follow the guidance in TCM0044060.

Note: Do not enter historical dates on the Applicants Details screen. Go to the applicable History screen and enter the dates there.

Note: Where there are several changes that have occurred at different times, you must attempt to apply the changes in sequence starting with the oldest change first. This does not apply to changes to employment details, which must always be completed last regardless of the sequence date. After updating or changing the employment details, you must go straight to the Amend Finish screen. Do not go to any other screen. Failure to do this will result in the new information being lost. Do not complete the Amend Finish screen until all the changes have been applied.

Note: Before leaving the Work Details screen, always go to the History screen to check that there are no overlapping periods of employment or hours worked. If there are, you must obtain the correct details and amend the dates accordingly.

Note: Employer Reference numbers are made up of two parts - for example, 493 / K202. The first part is a three-digit area number (district). The second part is the Pay As You Earn (PAYE) employer reference. When entering the details, you must enter the three-digit district number first, then enter the PAYE employer reference.

Note: When completing the Childcare Details screen, you must use ‘and’, you can not use an ampersand (‘&’).

To enable [OK], enter the data and tab out of the field. Where [OK] is disabled, do not cancel out, set and then unset a signal or go to another screen and select [OK].
