How Singapore SMEs Can Improve XBRL Data Consistency Year Over Year

For many Singapore SMEs, ACRA Annual Return filing and IRAS tax filing often feel like part of the same compliance process. While both are mandatory, they serve very different purposes, follow different timelines, and require different information.

Understanding the difference helps business owners plan better, avoid confusion, and reduce last-minute compliance stress.

Different Authorities, Different Objectives

At a high level, the key difference lies in who you are reporting to and why.

• ACRA Annual Return (AR) focuses on corporate compliance and transparency
• IRAS tax filing focuses on taxation and assessing how much tax a company needs to pay

Although both rely on financial data, they are not interchangeable.

What the ACRA Annual Return Is About

The Annual Return is a statutory filing submitted to ACRA to confirm that a company’s records and financial position are up to date.

It typically includes:

• Company information (directors, secretary, registered address)
• Confirmation of AGM or AGM exemption
• Financial statements submission (XBRL or PDF, depending on eligibility)
• Key dates such as financial year end and AGM date

The goal is regulatory transparency, not tax calculation.

Missing or incorrect Annual Returns can result in late fees, enforcement actions, and compliance issues for directors.

What IRAS Tax Filing Is About

IRAS tax filing determines how much tax a company needs to pay for a given year of assessment.

This involves submitting:

• Estimated Chargeable Income (ECI)
• Corporate Income Tax Return (Form C-S, C-S (Lite), or Form C)
• Tax computations and supporting schedules

The focus here is taxable income, allowable deductions, and compliance with tax regulations — not corporate records.

Deadlines and requirements are separate from ACRA filings.

Key Differences SMEs Should Know

While both filings rely on financial data, they differ in several important ways:

• Purpose: ACRA ensures corporate compliance; IRAS assesses tax
• Format: ACRA often requires XBRL; IRAS requires tax forms and computations
• Timing: Deadlines are different and not automatically linked
• Adjustments: Tax filings include tax adjustments that do not appear in statutory financial statements

Confusing one for the other often leads to errors or missed deadlines.

Why SMEs Often Get Caught Off Guard

Many SMEs assume that completing one filing automatically prepares them for the other. In reality, delays usually happen because:

• Financial records are not finalised early enough
• Data needs to be reworked for different reporting purposes
• Manual bookkeeping creates inconsistencies
• Last-minute adjustments surface late

The issue is rarely the rules — it’s preparation.

How Better Financial Data Supports Both Filings

Clean, structured bookkeeping makes both ACRA and IRAS filings far easier.

SMEs using AI-powered bookkeeping platforms like ccMonet benefit from:

• Consistent transaction categorisation
• Continuous reconciliation
• Accurate financial statements ready for XBRL
• Reliable data that supports tax computation

When financial records are well-managed, the same data foundation supports both compliance paths with minimal rework.

Two Filings, One Strong Foundation

ACRA Annual Returns and IRAS tax filings are different — but they depend on the same underlying financial data. SMEs that focus on maintaining accurate, structured records throughout the year avoid duplicated effort and last-minute panic.

Compliance becomes far easier when preparation is ongoing, not reactive.
