What Is XBRL Filing in Singapore?
XBRL, or eXtensible Business Reporting Language, is a digital reporting format used to structure financial information so that it can be read and processed by computer systems.
In Singapore, the Accounting and Corporate Regulatory Authority (ACRA) requires many companies to submit their financial statements in an appropriate XBRL format when filing their Annual Return.
Instead of submitting financial information only as conventional documents, XBRL assigns standardised tags to financial data. This allows information such as revenue, expenses, assets and liabilities to be processed more efficiently.
For Singapore companies, XBRL filing is therefore an important part of maintaining statutory compliance.
ACRA’s current requirements distinguish between different types of companies and financial statement formats, so businesses should determine their applicable filing requirements before preparing their submission.
Why Is XBRL Important for Singapore Companies?
XBRL is designed to make financial information more structured, consistent and machine-readable.
For regulators, this can improve the processing and analysis of corporate financial information. For businesses, accurate XBRL preparation can also reduce repetitive manual work and create a more organised reporting process.
However, XBRL should not be treated as simply converting a PDF into another file format.
The financial information must be appropriately mapped to the relevant ACRA taxonomy, reviewed and validated before submission.
This is why accounting accuracy is particularly important when preparing an XBRL filing.
Who Needs to File XBRL Financial Statements in Singapore?
The general rule is that Singapore-incorporated companies must prepare financial statements and file them with ACRA unless an exemption applies. The exact filing format depends on factors such as the company’s size, type and public accountability.
Depending on the circumstances, a company may need to submit:
- Full XBRL financial statements
- Simplified XBRL financial statements
- XBRL financial statements under the Financial Statement Highlights (FSH) framework for certain regulated entities
- Financial statements in PDF where the applicable ACRA requirements permit or require this format
Companies should not assume that every Singapore business uses the same XBRL template.
For example, ACRA currently identifies smaller and non-publicly accountable companies as potentially eligible for Simplified XBRL, subject to the applicable criteria. ACRA defines a smaller company using thresholds including revenue and total assets of no more than S$500,000 for the relevant financial year.
Some entities may also be exempt from preparing and filing financial statements altogether. One important example is a dormant relevant company that satisfies the applicable statutory conditions.
Because the rules can depend on the company’s circumstances, it is advisable to check the latest ACRA requirements before each filing.
Full XBRL vs Simplified XBRL
One of the first questions business owners often have is whether they need Full XBRL or Simplified XBRL.
Full XBRL
Full XBRL generally involves a more comprehensive representation of the company’s financial statements and related disclosures.
Financial information needs to be mapped against the relevant elements of the ACRA taxonomy. This can involve substantial tagging and review, particularly where a company has complex accounting arrangements or extensive notes to its financial statements.
Simplified XBRL
Simplified XBRL is intended for qualifying smaller and non-publicly accountable companies.
It requires less financial information to be tagged compared with the Full XBRL framework, making the preparation process more manageable for eligible smaller businesses.
The important point is that the company should establish which format applies before beginning the XBRL preparation process.
Using the wrong template can result in additional work and may create compliance issues.
How to Prepare XBRL Financial Statements in Singapore
Preparing XBRL financial statements is easier when the process is handled systematically.
- Finalise the company’s financial statements
Your financial statements should be completed and reviewed before beginning the XBRL conversion.
This provides the source information from which the XBRL filing is prepared.
- Determine the applicable XBRL format
Assess your company’s status, size and filing obligations to determine whether Full XBRL, Simplified XBRL or another applicable format should be used.
- Use BizFinx or approved accounting software
ACRA provides BizFinx, a preparation tool that companies can use to prepare and validate XBRL financial statements.
ACRA also permits companies to use approved accounting software or engage a corporate service provider to assist with XBRL preparation and filing.
- Map the financial information
This is one of the most technical stages.
Financial statement line items need to be matched to the appropriate concepts within the ACRA taxonomy.
For example, accounting information relating to revenue, assets, liabilities or expenses must be assigned the appropriate XBRL concepts.
- Validate the XBRL file
The prepared XBRL information should be validated before submission.
Validation can identify issues such as missing information, inconsistent figures or other business-rule problems.
ACRA recommends reviewing and correcting genuine validation errors before filing.
- Upload and complete the Annual Return
Once the XBRL financial statements have been prepared and uploaded, the company proceeds with its Annual Return filing through ACRA’s Bizfile platform.
ACRA currently states that XBRL financial statements uploaded through BizFinx remain available on the server for up to 14 days, and the Annual Return should be filed with the uploaded financial statements within that period.
What Documents Are Needed for XBRL Filing?
The exact documents depend on the company’s filing category and circumstances.
Generally, businesses should have their completed financial statements ready before starting the XBRL process.
Depending on the applicable requirements, information may include:
- Statement of financial position
- Income statement
- Statement of changes in equity
- Cash flow statement, where applicable
- Notes to the financial statements
- Accounting policies
- Comparative financial information
- Directors’ statement and other Annual Return information
The XBRL data should correspond accurately with the company’s authorised financial statements.
ACRA also notes that where a company submits a full set of financial statements in XBRL format, a separate PDF copy does not need to be attached. Where a full XBRL submission is not made, a PDF copy may be required depending on the company’s filing circumstances.
Common XBRL Filing Mistakes in Singapore
XBRL filing errors can create unnecessary delays, particularly when the underlying accounting records have not been properly reviewed.
Some common issues include:
- Incorrect taxonomy mapping
- A financial statement item may be assigned to an inappropriate XBRL concept.
- Choosing the wrong filing format
- A company may incorrectly assume that it qualifies for Simplified XBRL or another filing treatment.
Differences between accounting records and XBRL data
The figures in the XBRL submission should accurately reflect the company’s final financial statements.
Unresolved validation errors
Validation warnings and errors should be reviewed carefully rather than ignored automatically.
Last-minute preparation
Waiting until the Annual Return deadline to begin XBRL preparation leaves little time to resolve mapping or validation issues.
Outdated information
ACRA periodically updates its tools, taxonomy and guidance. Businesses should therefore work from the current requirements rather than relying solely on previous year’s filing procedures. ACRA released updated BizFinx and Multi-upload tools in February 2026.
When Is XBRL Filing Due in Singapore?
XBRL financial statements are generally submitted as part of the company’s Annual Return filing.
This means the relevant deadline depends on the company’s statutory Annual Return requirements rather than there being one universal XBRL deadline for every Singapore company.
Companies should check their Financial Year End, Annual General Meeting requirements and applicable Annual Return deadline.
ACRA advises companies to meet their statutory filing deadlines to avoid late filing consequences.
For this reason, it is better to prepare the financial statements and XBRL information well before the Annual Return deadline.
Can a Company Prepare XBRL Filing Without an Accountant?
Yes.
A company can use ACRA’s BizFinx preparation tool to prepare its XBRL financial statements internally.
However, DIY filing may become complicated when the company has:
- Multiple business activities
- Complex accounting transactions
- Group accounts
- Numerous financial statement notes
- Foreign currency transactions
- Significant changes from the previous financial year
- Unfamiliarity with the ACRA taxonomy
- Previous XBRL validation issues
ACRA itself provides three broad routes for preparing XBRL financial statements: BizFinx, approved accounting software, or assistance from a corporate service provider.
For companies without dedicated accounting expertise, professional assistance can reduce the administrative burden and help identify potential issues before submission.

Final Thoughts
XBRL filing is an important component of corporate compliance for many Singapore companies.
Although ACRA provides tools such as BizFinx for businesses that want to manage the process themselves, preparing an accurate submission requires more than simply uploading financial statements. Companies need to select the correct filing format, map financial information appropriately, validate the data and complete the Annual Return within the applicable deadline.
