Impact of Missing ID Verification

29 January 2026

November Deadline

The 18th November 2025 deadline for identity verification with HMRC and Companies House was a key requirement for all UK company directors and individuals managing tax affairs. Clients who did not complete the verification by this date face significant consequences — not only for themselves but also for their accountants.

As an accountancy practice, we are unable to file any tax returns, confirmation statements, or other statutory documents on behalf of clients who have not registered and verified their identity. HMRC and Companies House have made it mandatory that individuals verify their ID before third parties can act on their behalf. This means that until a client completes the verification process, we cannot submit Self-Assessment returns, pay taxes, or file company accounts digitally.

The implications are serious. Missed deadlines for tax returns or confirmation statements can trigger automatic penalties, interest on unpaid tax, and potential compliance issues with Companies House. For companies, failure to submit accounts or confirmation statements on time can also impact legal standing and creditworthiness.

Verify Your Identity

To prevent ongoing disruption, clients must register and verify their identity as soon as possible, even though the 18th November 2025 deadline has passed. Once verified, we can resume managing filings and ensuring compliance.

This process is crucial not just for compliance, but also for maintaining a smooth working relationship with Evans Entwistle. Verification ensures we can continue to handle tax returns, company filings, and other statutory obligations on your behalf without further delays or penalties.

Missed the Deadline?

Clients who have missed the deadline should take immediate action to complete ID verification with HMRC and Companies House to restore access and avoid ongoing compliance risks.
