Emerging Identity Verification Requirements: What Accountants Need to Know (ACSP)

The landscape of corporate compliance is changing fast. Under the Economic Crime and Corporate Transparency Act (ECCTA), identity verification (IDV) for company directors, Persons of Significant Control (PSCs), and anyone filing documents with Companies House is becoming mandatory. While voluntary IDV has been in effect since April 8, 2025, mandatory checks kick in from November 18, 2025, with a full transition wrapping up by November 2026.

Why it matters: This move boosts transparency and accountability in UK company filings. Firms like Matplus are well-positioned to lead the way.

What It Means for Matplus and Other Accounting Firms

To offer IDV or file on behalf of clients, firms must be registered as Authorised Corporate Service Providers (ACSPs). Registration began on March 18, 2025, and firms need to be ACSPs by spring/summer 2026 to continue filing for clients.

The process requires:

• AML supervision (e.g., via ICAEW)

• Accurate firm details (legal name, AML membership number)

• A one-off £55 application fee

Adding ID Verification: Risks, Opportunities & Best Practices

Risks to Consider

Providing IDV services increases regulatory exposure. Firms are held to strict standards—any mistakes could see your ACSP status revoked, along with the ability to file for your clients.

Choosing Your Verification Method

You can carry out IDV either:

• Manually, by trained staff using at least two approved documents (with at least one photographic), or

• Digitally, via ID Validation Technology (IDVT) that verifies documents using security features embedded in passports or licenses.

Training Requirements

For manual checks, staff must be trained to Home Office standards to recognize falsified documents. Even when using IDVT, firms remain responsible for confirming the authenticity of documents submitted.

What You Should Do Next

Decide whether to become an ACSP now—or hold off. If you want to include IDV in your service offering, register sooner. Otherwise, you still have until spring 2026 if you only need to file accounts on behalf of clients.

1. Ensure your firm record is accurate. Your legal name, AML number, and firm details must match Companies House and ICAEW records to avoid rejection.

2. Choose and invest in your verification approach. Manual checks need well-trained staff; automated IDVT requires investment in tech. Weigh the costs, benefits, and operational impact carefully.

3. Talk to your clients. Provide clear guidance on IDV options: direct via OneLogin, via Post Office, or through you as an ACSP. Make it part of your onboarding conversation.

TL;DR Table

By keeping ahead of these changes, Matplus can uphold client trust, reinforce compliance, and even offer IDV as a valuable new service. Need help drafting client-facing materials or preparing your team for ACSP application? We’re ready to assist.
