ONSCG4400 | Handling applications upon receipt: use of email
From HM Revenue & Customs · Non-statutory Clearance Guidance
Customers are encouraged to submit applications by email as these can be processed more efficiently by the Non-statutory Clearances Team. The customer guidance on GOV.UK states that attachments to emails should be no larger than 10 MB.
The annexes in the customer guidance on GOV.UK explain that:
HMRC cannot guarantee the security of emails sent to us or that we send to them over the internet - any information sent to us or by us via email is undertaken at the customer’s own risk
customers should assess the risks of using email to send information or to receive it from us
customers should specify in advance if they wish us to reply (where possible) by email confirming that they understand and accept the risks involved in using email
in supplying information about market/price sensitive matters or well-known individuals the use of email should be avoided; rather, sensitive information should be sent by courier or post (see also ONSCG4500)
customers should email the HMRC Non-statutory Clearances Team if they have any doubts about the authenticity of an email received which claims to come from the Non-statutory Clearances Team
