IRIS Accounts Production

Charities SORP 2026

The new Charities SORP 2026 was published on 31 October 2025 and is effective for reporting periods beginning on or after 1 January 2026, with early adoption permitted. IRIS Accounts Production has been extensively updated so that charity accounts meet the new SORP requirements across data entry, report output and iXBRL tagging.

Revenue recognition

A new income recognition model has been implemented for income from non-exchange transactions, with updated data screens, note content and report output, together with a supporting exception report and updates to accounts charts and group structures.

Lease accounting

Lease accounting has been aligned with the FRS 102 changes, covering the leasing note and accounting policy, balance sheet and lead schedules, the cash flow statement, and group structures, with an accompanying exception report.

Trustees’ Report

The Trustees’ Report has been restructured with new and updated data screens and report output across the following areas:

Reference and administrative details, including the Senior Management Team
Structure, governance and management
Objectives and activities
Achievements and performance
Financial review
Plans for future periods
Sustainability
The Strategic Report within the Trustees’ Report

Statement of Financial Activities (SOFA)

The SOFA has been revised, including the order of income notes, and removal of the “Small + SORP concessions” option.

Funds and further disclosures

Additional updates across the accounts include:

Fund movements note and improved handling of unrestricted and designated funds
Social investments (including ICHA and UCHA account description amendments)
Charitable activities note and income from non-exchange transactions
Asset measurement – at cost or at fair value
Tiering, disclosure exemption options and an early adoption data screen
iXBRL tagging updated to reflect the SORP 2026 requirements

Electronic submission of CIC accounts using the Companies House Zip Service

As part of the Companies House ECCTA reforms, Community Interest Company (CIC) accounts can now be prepared for electronic submission via the Companies House Zip Service.

CIC accounts are produced through the usual iXBRL route with the accompanying CIC34 report through Accounts Production.

Supporting changes include:

iXBRL tagging of the CIC34 report against the 2025 taxonomies, covering both the Simplified and Detailed versions
A new “Create CIC copy” action and an updated saving process for the generated iXBRL output
Production of the new iXBRL reports (accounts plus CIC report), with the iXBRL editor and interactive report
Upload to OpenSpace for client approval

Once the iXBRL files have been created, for customers with a Practice Management licence there is a new option to create the ZIP package within the Communication tab as described later in these release notes.

For customers that do not have a Practice Management licence we will be making a further change in Autumn release to allow for the same journey. In the meantime Companies House expect the package as a single ZIP file with the two iXBRL files held inside one folder named for the company.

Arrange the files like this:

<your-zip-name>.zip
└── CIC – {Companies House registration number}\
├── accounts ← the iXBRL of the accounts
└── cic34 ← the iXBRL of the CIC report

These package accounts can then be submitted directly with Companies House, further details can be found through this link.

SA103F and SA104F Trade comp and schedules of data updates for FIG regime

The SA103F (Sole Trade) trade computation and schedules of data have been updated to correctly reflect FIG profit claims and loss adjustments for the 2025/26 tax year, ensuring that the trade computation, tax computation, and schedules of data all display consistent and accurate values where a FIG claim is made.

The SA104F (Partnership) trade computation and schedules of data have similarly been updated to correctly handle FIG profit claims and loss adjustments for the 2025/26 tax year, ensuring consistency across the trade computation, tax computation, schedules of data, and the relevant SA104F form boxes.

The following updates have been made in the software:

The E-checklist has been updated for 2026
The Paper checklist has been updated for 2026

Next year rate updates

The Individuals and Trusts next year tax rates for 2027 have been updated.

Making Tax Digital

IRIS Accountancy Suite provides full end-to-end MTD ITSA functionality, supporting practices through the complete in-year and year-end submission cycle. The suite enables quarterly submissions for Self-Employment, UK Property, and Foreign Property income sources, before bringing everything together at year end through the Digital Tax Hub.

The year-end process completes the picture for these in-year sources — covering adjustments, allowances, and Business Source Adjustable Summary (BSAS) submissions — while also capturing all other income and reliefs not reported quarterly. This includes, but is not limited to, interest, dividends, employment income, pensions, and state benefits, ensuring practices can deliver a complete and compliant return from a single platform.

We continue to develop and build out this feature set with each release. This update includes the following improvements:

Seafarer’s Deduction

As part of this, we continue to expand the income sources and reliefs supported within the end of year submission. The latest addition is Seafarer’s Deduction, which allows practices to fully capture employment income by accounting for this relief alongside standard employment income figures. You can now submit Seafarer’s Deduction to HMRC directly from the Digital Tax Hub.

BSAS & Business Details Updates

Business Source Adjustable Summary (BSAS) is a submission made to HMRC to account for any year-end adjustments or accrual adjustments required against a business source. Where quarterly data has already been submitted to HMRC, IRIS retrieves a record of these submissions and compares them against the year-end position held within IRIS. The software then automatically calculates any adjustments required and displays them within the BSAS ready for submission, removing the need for manual reconciliation. BSAS is fully active and working for Self-Employment and UK Property sources.

Foreign Property has been brought in line with the same functionality, with the BSAS schema updated to support submissions for tax year 2026-27 onwards

End of Year Manual Adjustments

MTD users can now make manual end of year adjustments to trade/property figures directly in Personal Tax. This is particularly useful where quarterly submissions have already been made, whether through IRIS or a third-party bookkeeping solution, and no accounts are being prepared. Adjustments can be entered manually without the need to return to the bookkeeping source, giving practices greater flexibility at year end.

IRIS Business Tax

CT600A-Loans to Participator rate update

The CT600A new loans data entry has been updated to apply the revised s455 rate of 35.75% for accounting periods on or after 6 April 2026, with straddling periods now displaying pre and post 06/04/2026 columns to ensure the correct rate is applied. The CT600A repayment and write-off data entry has also been updated to apply the revised rate, with straddling periods now showing pre and post 06/04/2026 columns to calculate relief at the correct rate.

Finally, the Enhanced Computation report has been updated to reflect the revised s455 rate of 35.75% for accounting periods on or after 6 April 2026, correctly splitting pre and post 06/04/2026 amounts for straddling periods. Please note, HMRC’s Corporation Tax online service will not be updated to support the new rate until 6th April 2027. Please contact HMRC for further guidance on how to proceed.

IRIS Practice Management

Data Mining IDV Codes

Practice Administrators can now data mine the IDV (Identity Verification) field within IRIS Practice Management. IDV codes recorded against each client on the Client Maintenance screen and are used to track completion of identity checks for ECCTA compliance and regulatory reporting. Previously there was no way to report on these codes in bulk, which made it hard to spot gaps or run compliance audits. This release adds a dedicated data mining capability for the field.

As an Admin user of the practice, you can now:

Bulk list view: open the Datamining report in Practice Management and add the IDV Code field to see every client’s client ID, client name, and IDV code in one list.
Search by IDV code: enter a full or partial IDV code in the search field to filter the list to matching clients only.
Filter by status: with the IDV Code field selected, filter the client list using contains, is (exactly), doesn’t contain, is empty, and is not empty.
Identify missing codes: apply the “is empty” filter to surface only clients with no IDV code recorded, making compliance gaps easy to find.
Export results: export any filtered result set to a .csv file containing all visible columns, for offline review or audit records.

Companies House Submission: CIC Accounts

For Practices submitting Community Interest Company (CIC) accounts, files produced by Accounts Production are now stored against the client in the Communications tab, ready for submission to Companies House. A one-click option to package these files into a Companies House-ready ZIP is available.
