Limerick, Ireland, 17 September 2025. Chern & Co Ltd, a provider of corporate, accounting, and compliance services for international entrepreneurs, has been officially registered with HM Revenue & Customs (HMRC) as an authorised tax agent for Self Assessment and Corporation Tax. The registration was confirmed by the Agent Compliance Team (HMRC, BX9 2BG, UK). This milestone strengthens Chern & Co’s cross-border capabilities, allowing the firm to act on behalf of clients in their dealings with HMRC, from submitting tax returns and obtaining authorisations to supporting compliance with UK tax obligations.
Why it matters
- Official representation: the firm can communicate with HMRC and manage filings for Self Assessment and Corporation Tax on behalf of its clients, once each client authorises Chern & Co.
- Cross-jurisdiction support: the registration improves coordination for businesses operating in both the UK and Ireland, simplifying administration across the two markets.
- Regulatory background: Chern & Co Ltd is a licensed Irish Trust and Company Service Provider (TCSP APP/1211/2018), authorised and supervised by the Department of Justice in Ireland.
“Obtaining HMRC agent status reflects our continued focus on transparent, compliant, and technology-driven business support for founders working across the UK and Ireland.”

What an HMRC-authorised agent can do for you
Once a client authorises Chern & Co as their agent, the firm can act on the client’s behalf with HMRC for Self Assessment and Corporation Tax. In practice, this means Chern & Co can prepare and submit the relevant returns, correspond with HMRC on the client’s tax affairs, and carry out the day-to-day agent tasks that HMRC permits for these taxes. Authorised agents operate through an HMRC agent services account, and the scope of what an agent may do is set out in HMRC’s guidance on how to get authorised to act as a tax agent. As a registered agent, Chern & Co is expected to meet the HMRC standard for agents, which requires agents to be straightforward and honest in their dealings with HMRC. This UK work sits alongside the firm’s accountancy and tax services.
What this means for cross-border clients
Many of Chern & Co’s clients operate under two systems at once. An Irish company owner may also carry UK obligations, for example UK Corporation Tax on a UK activity, or UK Self Assessment on a UK-source personal liability. Equally, a UK-linked founder may use Ireland as an EU base while keeping UK filing duties. HMRC agent status lets Chern & Co handle the UK side directly with HMRC, while the firm’s Irish team continues to manage Irish filings with the Revenue Commissioners. The two regimes stay separate: UK taxes are dealt with under UK rules through HMRC, and Irish taxes under Irish rules through Revenue. For online sellers trading into both markets, this joins up with the firm’s support for EU and UK sellers and its UK VAT registration service.
How authorisation works
HMRC does not publish a public register that clients can search to confirm an agent relationship. Instead, authorisation is confirmed through the client’s own HMRC account. For Self Assessment and Corporation Tax, Chern & Co sends the client a secure authorisation request, and the client approves it by signing in to their HMRC account and completing the digital handshake. This keeps the client in control: the agent link becomes active only once the client approves it, and the client can review or remove the authorisation through their HMRC account at any time. Further detail on the firm and its licences is on the About us page.
