ACRA Releases BizFinx PrepTool v4.0 & Multi-Upload Tool v4.0
What Singapore Companies Need to Know
On 25 February 2026, the Accounting and Corporate Regulatory Authority (ACRA) rolled out the newest versions of its BizFinx Preparation Tool (Preptool) v4.0 and Multi-Upload Tool (MUT) v4.0. These are critical tools for companies preparing and filing XBRL financial statements with ACRA.
From now until 15 April 2026, businesses must transition to these updated versions to continue preparing, validating and uploading their XBRL files without interruption.
Below is a breakdown of what has changed, why it matters, and how companies should act.
Why the Update Matters
ACRA’s tools help preparers convert financial statements into XBRL (eXtensible Business Reporting Language) – the digital reporting format required for statutory filing in Singapore. Using the correct version ensures compliance with updated reporting standards and avoids filing errors or rejection.
What’s New in v4.0
The updated Preptool and Multi-Upload Tool include several key enhancements designed to make reporting easier and more accurate.
Update Category | Before (v3.x) | Now (v4.0) |
Accounting Standards | Older taxonomy based on prior FRS versions | Updated for FRS 117 (insurance contracts) reflecting current accounting practices |
Disclosure Requirements | No option for reduced disclosures | Eligible companies can now choose “SFRS (Reduced Disclosure Requirements)” where applicable |
Additional Information | No dedicated field for extra metadata | New “AdditionalInformation” tab supports richer data tagging and analysis |
Validation Rule Classification | Some strict error flags required exemptions | Certain rules re-classified as “possible errors” → fewer exemption requests if preparer confirms non-error |
Backward Compatibility | Older files might have compatibility issues | All Excel or XBRL.zip files from prior versions open safely in v4.0 without data loss |
Key Insight: These changes reflect ACRA’s move toward more flexible, transparent, and analytics-friendly reporting – particularly for companies using reduced disclosure regimes and those subject to newer accounting standards.
Timeline & Action Checklist
Date | What Happens | Required Action |
25 Feb 2026 | v4.0 tools become available | Start using the latest Preptool & MUT immediately. |
Now–15 Apr 2026 | Transition window | Uninstall any older versions and install v4.0. |
After 15 Apr 2026 | Older versions no longer accepted | Only v4.0 can prepare, validate and upload filings. |
Who Should Care
All incorporated entities that must file XBRL financial statements with ACRA – including local private companies, public companies, and foreign entities with Singapore branches – need to migrate to the updated tools by the deadline.
This includes:
- Accountants and auditors
- Corporate secretarial firms
- Finance teams in SMEs and larger groups
- Corporate service providers (CSPs) handling regulatory filing
Failing to upgrade before the deadline could result in submission errors or delays.
How to Upgrade
- Visit the ACRA download page for BizFinx tools.
- Uninstall older versions of Preptool or MUT.
- Install BizFinx Preparation Tool v4.0 and Multi-Upload Tool v4.0.
- Open your existing Excel/XBRL files in the new tool – they will load seamlessly.
Tip for practitioners: Validate early – especially if using reduced disclosure formats – to avoid surprises close to filing deadlines.
Closing Thoughts
ACRA’s 2026 BizFinx update is more than a simple software refresh. It aligns Singapore’s XBRL filing ecosystem with current accounting standards, enhances flexibility around disclosure choices, and streamlines common validation pain points. Early adoption will save preparers time and support compliance with Singapore’s regulatory timetable.
