Overview

The IRIS Accountancy Suite Autumn release version 25.4.0 focus is on the Companies House Identity verification updates that are happening on the 18th November. In Personal Tax, a brand-new intelligent validation option, (AI powered), that analyses current and previous returns, identifying any changes that require attention, designed to save you time and improve accuracy. This release also delivers resolutions to issues found in previous releases as well as legislative updates. 

Company Secretarial and Company Formations 

ECCTA Identity verification (IDV) update
From 18th November 2025 all companies will need to ensure current Directors, PSC’s and LLP Members have their identities verified either with Companies House directly using gov.uk one login or through agents as Authorised Corporate Service Providers (ACSP).  Any new appointments/ incorporations with the same role(s) will also need to be verified as part of the process. 

After installing this update, the software will continue to work and operate in the same way it does today allowing you to continue to file documents under the current regime.  Then at 6pm on the 17th of November, Companies House will close their digital services. From 9am on the 18th of November the software will dynamically change to introduce a range of updates as described below allowing you to seamlessly transition into the new updated compliant workflows that are required for IDV. 

IDV code 
Within the Personal Client Maintenance screen, we have introduced a new IDV field. The IDV code can be obtained directly by the individual using a self-serve method using gov.uk one login or if you are registered as a ACSP with Companies House, you can verify the individual and then an IDV code will be issued to the individual. 

Confirmation Statement (CS01, LLCS01) 
We have introduced the new Confirmation Statement that now mandates that any existing director(s) or LLP member(s) must include the IDV code as part of the next submission. If an IDV code is missing for a specific individual the software will prevent the submission. The updated form includes a new F2 section for the IDV code.  

Persons of Significant Control (PSC) (VS01) 
For existing individuals who are PSC’s they need to confirm their identity with Companies House within 14 days of the month they were born.  To help simplify this we have introduced a new report that will show all PSC’s born in a specific month.  From within the Company Secretarial product this report can be found under Administration, PSC Identity Verification Report.  The report includes individuals who are PSC based on a date of birth month range selected.  It also has an option to include individual who are PSC where their date of birth is missing. The report includes the Client ID, Name of the individual PSC, Date of Birth, IDV Code, corresponding PSC Business ID, Business Name and if the PSC IDV has been submitted and accepted through the software for the specific business.

* The VS01 is not an official Companies House form and has been produced to illustrate what is being submitted in the software to Companies House.

To complete IDV submissions for existing PSC’s we have also introduced a new VS01 form. This is triggered by entering the individuals IDV code. The VS01 form and event will not be triggered for any new appointments of PSC’s on or after the 18th of November as this information will be captured in the new PSC01 for Limited Companies and LLP equivalent. The VS01 will not be accepted as a paper form by Companies House and will be rejected, so must be submitted digitally from the software. 

For existing Persons of Significant Control who are also a Director (or an LLP Member) of the same incorporated business, they must submit IDV codes for each role at the anniversary of the next Confirmation Statement. If you try to submit the Confirmation Statement within the normal 14 review period and on the same day submit the separate VS01, Companies House will reject the VS01, this is down to the way the law was written.   

In this instance the VS01 can only be accepted from 1 day past the normal 14-day review period window of the Confirmation Statement.    

There are two ways to resolve this: 

  • you can either file the Confirmation Statement within the normal time frame and then the VS01 on the 15th day (being the confirmation statement review period window plus 1 day).   
  • or you can file the Confirmation Statement 1 day late and complete the VS01 submission at the same time.   

Companies House have accepted this is a perfectly reasonable excuse for the late filing of the Confirmation Statement. The above paragraph only applies to individuals who are both a Director or LLP member and a PSC of the same incorporated business. 

Appointment of Director or LLP Member (AP01 or LLAP01)
We have introduced an updated Appointment of Director AP01 form which now includes the IDV field and removes the need to include an occupation.  If the IDV code isn’t present it will flag in the e-file exceptions report and prevent e-filing.  

PSC new statement 
PSC statements have been updated to the following: 

  • “The company knows or has cause to believe that a person has become a registrable person or a registrable relevant legal entity in relation to the company, but it has not yet had confirmation.” 

It replaces these two previous PSC Statements: 

  • “The company knows or has reasonable cause to believe that there is a registrable person in relation to the company, but it has not identified the registrable person.” 

and 

  • “The company has identified a registrable person in relation to the company but all the required particulars of that person have not been confirmed.” 

Changes to Company Registers 
From the 18th November there will no longer be a requirement for companies to hold the following registers as described below and as such we have removed the option for location of register. The register themselves will still be accessible from the software. 

  • Register of directors 
  • Register of directors residential address 
  • Register of secretaries 
  • Register of people with significant control 

Company Formations (IN01) 
When incorporating a new company, all Directors and PSCs will need to include an IDV code prior to e-filing.  If this is omitted, then it will be included in the E-file exceptions report. 

IRIS Personal Tax 

AI powered Anomaly Detection  
Introducing our first AI-powered feature in IRIS Personal Tax. 

We’ve enhanced the tax return filing process with intelligent validation that gives you an extra layer of confidence. When you select this new option, the system securely analyses certain income types of the current and previous year’s tax returns, intelligently identifying significant changes that merit your attention.  

You’ll receive a comprehensive comparison highlighting key differences between years, helping you ensure accuracy and catch potential issues before filing. This additional layer of review gives you greater confidence in your tax return submissions. 

The types of income included will gradually be increased to all entries on the Return over the coming weeks.  

Resolved issues: 

  • Farmers averaging profit for 2024 is now being calculated correctly. 
  • Overlap relief used in 2024 was incorrectly used against Partnership interest in 2025. 
  • An error message was being displayed when offsetting losses against other income for 2025.  
  • Personal Tax was miscalculating the SA104 Partnership share where the partner ceased/left the Partnership part way through the tax year.  
  • The full transitional amount was not being retained in Step 5 for 2024 and 2025 returns.  
  • When a user had a standard profit and transition loss, the loss brought forward was being used against the whole standard profit and not considering the offset of the transition loss. 

IRIS Making Tax Digital 

We continue to refine and enhance the Making Tax Digital (MTD) functionality within IRIS Personal Tax, addressing a number of reported issues to improve stability, accuracy, and overall user experience. 

Resolved issues: 

  • Consolidated expenses can now be retrieved from HMRC. 
  • Import functionality now working for TY 2026. 
  • Users can now match IRIS bank accounts with retrieved HMRC bank accounts. 
  • Can now retrieve Custom Employment details from HMRC. 

IRIS Business Tax 

Resolved issues: 

  • In certain circumstances the calculation of notional tax for an RDEC claim for periods starting on or after 01/04/2024 was using the incorrect rate of tax. This affected a scenario where when the taxable expenditure credit is excluded from chargeable profits resulting in a loss. The main rate of tax was being used instead of the small profits rate. 
  • In Business Tax, boxes 653 and 659 was not being completed correctly when the R&D SME screen was populated for periods on or after 01/04/2023.  

IRIS Trust Tax 

HMRC Special Case ID11 
Due to a system error, under certain circumstances, HMRC expects a value, including zero, to be present in box 9B.1 ‘Number of other trust rate trusts’ as part of the SA900 online submission. Whilst the submission would not be rejected initially, it would be rejected later, on HMRC’s end. The HMRC provided workaround is automatically applied to ensure that the submission is no longer rejected at any stage of the online filing process. 

Tax Legislation updates:

  • Updated Form 50FS for 2025
