Companies House has released a significant set of updates relating to People with Significant Control (PSC) rules, identity verification (IDV), and various statutory forms. These updates support the implementation of the Economic Crime and Corporate Transparency Act (ECCTA), the most substantial reform in Companies House history. 

Here’s a clear summary of what’s new and how it may affect your work. 

New & Updated PSC Guidance (Published 19 November 2025) 

Companies House has released multiple guidance documents to help companies, PSCs, and agents comply with strengthened PSC and transparency requirements. These are: 

• PSC Summary Guidance: Overview of PSC requirements for companies with simple ownership structures. 

• PSC Register Guidance: For individuals who may be PSCs and need clarity on their obligations. 

• PSC Guidance for Scottish Partnerships (ESPs): Explains PSC responsibilities specific to Scottish partnerships. 

• PSC Guidance for Legal Entities: Detailed rules for larger or more complex ownership structures. 

These updates aim to help businesses understand when PSCs must verify their identity, what information must be maintained, and how to comply under ECCTA. 

Updated Identity Verification Forms & Filing Processes 

Companies House has published new and updated forms relating to identity verification, new versions of PSC notification and update forms, and forms for Director Appointments, and Terminations & LLP Registrations. These updates support the rollout of mandatory ID verification for directors, PSCs, and filing agents. 

Request forms:

• Transparency data: Companies House purchase ledger spend 2025: Information about our purchase ledger spending 2025. 

These documents signal Companies House’ shift toward a more digital, regulated, and transparent corporate register. 

What This Means for Accountants 

With the introduction of ECCTA, accountants and company secretaries should expect: 

✔ Stricter ID verification 

Every director, PSC, and filing agent must verify their identity. 

✔ More accurate PSC registers 

Incorrect or incomplete PSC information could lead to rejected filings. 

✔ Increased client dependency 

Clients will require more support understanding IDV requirements and completing PSC updates. 

✔ Higher compliance expectations 

More detailed guidance means fewer excuses for non-compliance.

The post New Companies House PSC & ID Verification Updates: Key Changes Accountants Should Know  appeared first on capium.

HMRC has begun rolling out a new sign-in experience as part of its long-term plan to modernise how taxpayers and agents access digital services. From 10 November 2025, users signing into HMRC online services may have noticed a new login page that now includes the option to sign in using GOV.UK One Login. 

But despite the new visual appearance, nothing changes yet in terms of how you or your clients access HMRC services. 

What’s Changing? 

HMRC has added a GOV.UK One Login button to the sign-in page. This is part of the government’s wider plan to replace multiple legacy login systems with one unified, secure authentication platform. 

However: 

• Users must continue to log in using their Government Gateway ID and password 

• GOV.UK One Login cannot be used to sign into HMRC yet 

• Anyone who clicks the One Login button will simply be redirected back to Government Gateway 

• Even users who already have a GOV.UK One Login for other government services cannot use it for HMRC at this stage 

This is purely a visual, preparatory update. 

Using Capium as a third-party software 

From 19 November 2025, users authenticating through 3rd-party software will also see the new sign-in page during OAuth authorisation. 

Again, there is no change to how access is granted: 

• Keep using Government Gateway ID (10–12 characters) and password 

• OAuth flow remains the same 

• No technical changes required from developers 

• Capium integrations continue to function exactly as usual 

What Should You Tell Clients? 

Advise clients to: 

• Continue using Government Gateway 

• Ignore the GOV.UK One Login button for now 

• Avoid creating a new One Login account specifically for HMRC (it won’t work yet)

To Sum It Up:

This update is part of the government’s gradual shift toward a unified login system, but for now: 

✔ No action required
✔ No change to access or workflow
✔ No change to Capium authorisations
✔ Simply continue using Government Gateway 

As HMRC moves closer to fully adopting GOV.UK One Login, we’ll keep Capium users updated every step of the way.
