CIS submission query

Hello there, @john-fox-teece.

HMRC could reject your return for several reasons. Please review the checklist below before attempting to file a return again:

• You may be using the wrong login details. Log into the HMRC website to confirm that your Government Gateway user ID and password are correct.
• Use the right 10-digit Unique Taxpayer Reference (UTR) number.
• Review that you're using the correct PAYE Reference number.
• Check that your suppliers have the correct references and CIS setup:
  • Accounts Office reference number
  • Subcontractor UTR number
  • National Insurance (NI) number
  • Verification number
• Delete any special characters and additional spaces in the subcontractor/contractor name field. Only use letters A-Z and numbers 0-9.

If the same thing happens, we can perform some troubleshooting steps to fix this. There are times that the browser is full of frequently accessed page resources, which causes some unusual responses.

We can use either of these shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

Once done, try to submit your CIS.

If the submission goes well, go back to your regular browser and clear its cache. Also, an alternative way is to use other compatible browsers.
