Agent Services
Qualified accountants and bookkeepers can file MTD updates on your behalf once you authorise them through HMRC Agent Services.
- You remain legally responsible for accurate returns
- Check agent is registered and ideally professionally regulated
- Review figures before each deadline
What it is
HMRC’s Agent Services Account lets qualified agents act for multiple clients. You must authorise your agent to view and submit data for your business.
Authorisation is per client relationship. Agents use an Agent Services Account. Clear communication on record deadlines supports timely filing — submission quality depends on the accuracy of the records supplied.
Who it applies to
Anyone using an accountant, bookkeeper, or tax adviser registered with HMRC as an agent.
What you need to do
- Choose an agent registered for MTD services.
- Authorise them through your HMRC business tax account or using an authorisation code.
- Review submissions before deadlines.
Key points
- You remain legally responsible for your tax return even if an agent files it.
- Check your agent is regulated (e.g. ICAEW, ACCA, AAT) where applicable.
Common mistakes to avoid
- Providing incomplete records immediately before a filing deadline
- Assuming the agent is liable if figures are wrong
- Not authorising the correct business in HMRC
