Correctly signing the agent authorisation form

In order for us to act on your behalf, we need to have an authorisation form signed by you, which we present to HMRC when making a claim for a stamp duty reclaim on your behalf.

Nick Garner from the Stamp Duty Advice Bureau explains how to properly sign an authorization form digitally and physically. The instructions received via email guide you through the digital signing process.

The document can then be printed for a physical signature. For the physical signature, a ballpoint pen (preferably black or dark blue) is used, as the HMRC requires a ‘wet’ signature, meaning a signature made in ink, not a digital one.

A high-resolution photo or scan of the signed document should then be taken, ensuring all text is visible and clear, with an additional close-up photo of the signature for clarity. These images need to be crisp and easy to read, as they will be printed out by the HMRC. The HMRC accepts this method, especially when dealing with overseas clients where sending a physical document can be challenging.

The wording of the document is straightforward. It identifies the signatory and grants authorisation for the Stamp Duty Advice Bureau to liaise with HMRC on their behalf. It also provides details about the entity (individual or company) responsible for the payment.

The document also includes a Statement of Truth, though not obligatory for an authorization form. This section confirms the correctness of the information provided, and adds that any attempt to intentionally provide misleading or false information can result in penalties. Thus, the HMRC, upon reading this document, will understand that the signatory accepts responsibility for the accuracy and truthfulness of the information provided.
