To maximise efficiency and accuracy, HMRC prefer agents to use the online tax registration service (OTRS) when registering clients for SA and NIC. Where this cannot be done the new version of form CWF1 must be used. From 1 February 2013, HMRC will return old forms CWF1 as they do not provide enough information. The new version of Form CWF1 will be integrated into 3rd party software.
The new form CWF1 is available through the forms quick link on the HMRC home page.
HMRC’s alert states:
‘Registering for Self Assessment and National Insurance using form CWF1
When registering your client’s business HMRC recommends that you use the online tax registration service to register for Self Assessment and Class 2 National Insurance. It's quicker and easier than downloading a form. Follow the link below.
If you decide to send form CWF1 instead please be sure to download the latest version. From 1 February 2013, HMRC will return old forms as they don't provide enough information. The new version of Form CWF1 will be integrated into 3rd party software.
Recent analysis has shown that a high proportion of the CWF1 forms received by HMRC are old versions which sometimes include incorrect contribution rates or exception levels.
From 1 February 2013 HMRC’s Central Agent Authorisation Team (CAAT) will be returning ‘old’ or ‘incorrect’ versions of the CWF1. A covering letter will accompany the returned CWF1 explaining that we are unable to accept the form and suggesting alternative methods for registering as self-employed.’
