Why you’re seeing this error on your submissions

You may see this error if there’s a mismatch between the contractor details in BrightCIS and HMRC’s records. Work through the checks below in order:

1. Match the legal name
   Check that the contractor’s legal name in BrightCIS exactly matches HMRC’s records, including “Ltd” vs “Limited”, punctuation, and spaces.
2. Check the UTR
   Make sure the Unique Taxpayer Reference (UTR) is 10 digits long and has been entered correctly.
3. Confirm HMRC verification
   Ensure the contractor has been verified with HMRC. In BrightCIS, go to Submissions > Verification Requests to check the verification status.
4. Newly registered contractors
   If the contractor has only recently registered with HMRC, wait 24–48 hours for HMRC’s records to update before you resubmit.
5. If the error still appears
