Taxpayers retain ultimate legal responsibility for their tax affairs, even when an agent is authorised to act on their behalf.

HMRC has recently issued significant `HMRC agent authorisation guidance updates`, detailing the procedures for individuals and businesses to grant authority to professional tax representatives. These revisions primarily concern paid agents, such as accountants and tax advisers, outlining how they can interact with HMRC on behalf of their clients. The updated guidance clarifies that the specific method for authorising an agent varies depending on the tax service required, necessitating the use of either traditional paper forms or dedicated online platforms. This comprehensive overhaul aims to streamline the process while ensuring clarity on the scope of agent access.

The updated information emphasizes that taxpayers retain ultimate legal responsibility for their tax affairs, even when an agent is authorised to act on their behalf. It is crucial for individuals to meticulously review any information prepared by their agent and confirm its accuracy before submission to HMRC. This foundational principle underpins all interactions, regardless of the specific tax type or authorisation method employed.

Among the notable `HMRC agent authorisation guidance updates` are several specific changes to forms and online services. The guidance now explicitly states that the paper `HMRC form 64-8` must be both signed and dated by the taxpayer for it to be valid, a clarification added to the 'Download the form' section. Furthermore, the information regarding the completion of `HMRC form 64-8` has been updated to provide clearer instructions. A new dedicated section has been introduced, focusing on how to `Authorise tax agent UK compliance check` procedures, which includes a direct link to `HMRC COMP1a form guidance` for this specific purpose.

The scope of agent access has also been expanded and clarified for various digital services. The 'What an authorised agent can do on your behalf' section now includes an entry for `Making Tax Digital Income Tax agent access`, detailing how agents can manage client affairs under this regime. A new online tool has been integrated into the VAT section, offering additional guidance for `VAT agent online services HMRC`. Additionally, a new section has been added to explain how to provide `Limited agent authorisation HMRC` to an agent, allowing for more tailored access rights. Notably, references to form TC689, previously used for authorising agents for Tax Credits, have been removed from the 64-8 form. While form TC689 is still used for authorising intermediaries for existing tax credit claims, new tax credit claims have ended, with individuals now directed to Universal Credit or Pension Credit. The 'How to authorise an agent' section has also been revised to advise taxpayers to check all available authorisation methods for the specific tax services they require.

Once an agent is properly authorised, their level of access varies significantly across different tax categories. For instance, agents can access a client's returns, as well as details concerning subcontractors' income and deductions under the Construction Industry Scheme. For Corporation Tax, authorised agents gain access to relevant company tax information. Regarding employers' PAYE, agents will have access to sensitive employee personal and financial data. Submitting the 64-8 form specifically for Individual PAYE purposes grants agents the necessary access to these details.

For Self Assessment, agents can access various personal details such as employment, pension, bank interest, dividends, and property income, though individuals must first be registered for Self Assessment before authorising an agent. If a Self Assessment account already exists, `HMRC form 64-8` can be used for authorisation. In the context of tax credit claims, authorised agents can access personal and financial information and act on behalf of the claimant, but they are explicitly prohibited from receiving payments, and all correspondence will continue to be sent directly to the claimant. For joint tax credit claims, both claimants must sign the authorisation form. For trusts, agents authorised through the online service can access personal and financial information, but the 64-8 authority does not grant access to the trust's online service; instead, agents can act in writing or by telephone only and access details like income, expenses, beneficiaries, and capital gains.

Lawyers and compliance officers must review these updated HMRC procedures for authorising tax agents to ensure their clients' tax affairs remain compliant, particularly concerning new requirements for forms like 64-8 and COMP1a, and the expanded scope of agent access for services such as Making Tax Digital for Income Tax.
