XBRL Filing Singapore: How to Handle Data Corrections Without Restarting

For many Singapore SMEs, discovering an error during XBRL preparation can feel like hitting reset.

A retained earnings mismatch.
A misclassified liability.
An equity tagging issue.

The instinct is often to restart the entire process — regenerate reports, rebuild mapping, and re-validate everything from scratch.

But most data corrections don’t require a full restart. What they require is structured handling.

Here’s how to correct data efficiently during XBRL filing without destabilising your entire submission.

1. Identify Whether the Error Is Structural or Tagging-Related

Before making changes, determine the nature of the issue.

Ask:

• Is the number itself wrong? (Structural issue in the ledger)
• Or is the number correct but mapped incorrectly? (Tagging issue)

If it’s purely a tagging error, you likely don’t need to regenerate financial statements — only adjust taxonomy mapping.

If it’s a structural data problem, correction must begin in the accounting system — not the XBRL file.

Clarity here prevents unnecessary rework.

2. Correct at the Source — Not in the XBRL Output

One common mistake is fixing numbers directly in the XBRL tool.

This may allow validation to pass temporarily, but it creates misalignment between:

• Accounting records
• Financial statements
• Filed XBRL data

Instead:

• Correct the ledger entry
• Regenerate the trial balance
• Update financial statements
• Then regenerate the XBRL file

Fixing the source ensures long-term consistency and prevents recurring errors next year.

3. Contain the Impact of the Adjustment

Not all corrections affect the entire file.

After identifying the issue:

• Trace which financial statement sections are impacted
• Confirm whether equity movement is affected
• Check whether comparatives require adjustment
• Review related notes or disclosures

Limiting corrections to affected sections avoids unnecessary remapping.

Structured accounting systems make impact analysis easier by maintaining linked financial elements.

AI-powered platforms like ccMonet help centralise financial data and preserve structured relationships between accounts, reducing the risk of cascading corrections.

4. Validate Equity and Retained Earnings Immediately

Most structural corrections impact equity.

After making adjustments:

• Confirm assets still equal liabilities plus equity
• Reconcile net profit to retained earnings movement
• Validate dividend and share capital treatment

Equity misalignment is one of the most common causes of repeated validation failures.

Always review equity after making any correction.

5. Maintain Version Control Discipline

During correction cycles, avoid:

• Creating multiple spreadsheet versions
• Editing numbers in parallel files
• Overwriting prior adjustments

Instead:

• Maintain one controlled version
• Document each correction clearly
• Archive previous versions properly

Structured systems reduce version confusion significantly compared to manual spreadsheet workflows.

6. Re-Run Validation Strategically

After making corrections:

• Run validation checks immediately
• Address any secondary issues
• Confirm that comparatives remain stable

Don’t wait until the end of multiple changes to validate — incremental validation prevents compound errors.

7. Avoid Over-Correction

When under time pressure, teams sometimes introduce additional adjustments to “make things balance.”

This often creates new issues.

Instead:

• Correct only what is necessary
• Confirm logical flow
• Resist cosmetic fixes

Structural consistency matters more than presentation aesthetics.

8. Document the Correction for Future Stability

Once resolved:

• Record what caused the issue
• Update internal processes if needed
• Adjust reconciliation workflows
• Lock corrected balances

Many recurring XBRL errors happen because prior corrections were not systemised.

Good documentation prevents repetition.

Corrections Should Strengthen — Not Destabilise — Your Filing

Data corrections during XBRL preparation are normal.

The key difference between a smooth correction and a disruptive restart lies in:

• Fixing at the source
• Containing the impact
• Validating logically
• Maintaining structured version control

When bookkeeping systems are reconciled and structured year-round, corrections are smaller and easier to manage.

If your SME wants fewer disruptive filing cycles, strengthening financial data discipline before filing season begins is the most effective long-term solution.
