Do you actually need a statutory audit?
Not every Singapore company is required to undergo a statutory audit. Under ACRA’s current small-company audit exemption framework, a private company generally qualifies for audit exemption if it meets at least two of three quantitative criteria for the immediate past two consecutive financial years.
Annual Annual Revenue
≤ S$10m
Total assets
≤ S$10m
Full-time employees at FYE
≤ 50
Newly incorporated companies are assessed under specific first- and second-year rules. Audit exemption also does not remove the company’s wider obligations to keep proper accounting records, prepare financial statements where required, and meet filing obligations.

Current position: ACRA announced on 26 February 2026 that it is reviewing the audit exemption framework, including the revenue and asset thresholds. Until changes are formally introduced, the current published S$10 million / S$10 million / 50-employee criteria remain the reference point.
Group companies: the exemption test does not stop at the subsidiary.
If a Singapore company is part of a group, the company itself must qualify as a small company and the entire group must also satisfy the small-group criteria on a consolidated basis. That group assessment can include foreign entities.
This matters for Singapore subsidiaries whose own revenue and assets are small but whose parent group is significantly larger. Looking only at the local entity may lead to the wrong conclusion.
Practical point: If there is a holding company, obtain the group’s consolidated revenue, assets and employee count before concluding that the Singapore subsidiary is audit-exempt.
Key statutory and tax filing deadlines
For a typical non-listed Singapore company, the financial year end drives the annual compliance calendar. The dates below are useful reference points, but special circumstances can change the applicable deadline.
Obligation
Typical deadline
Hold AGM, where an AGM is required
Within 6 months after FYE
File Annual Return with ACRA — non-listed company
Within 7 months after FYE
File Annual Return — non-listed company with a share capital and overseas branch register
Within 8 months after FYE
File Corporate Income Tax Return (Form C-S / C-S Lite / C)
By 30 November each year, subject to IRAS filing rules

What happens if the Annual Return is filed late?
ACRA applies late lodgment penalties automatically when a company files its Annual Return after the deadline. For filing due dates on or after 14 January 2022, the current published penalty is:
Length of default
Late lodgment penalty
Up to 3 months after the deadline
S$300
More than 3 months after the deadline
S$600
Late lodgment penalties are not necessarily the end of the matter. ACRA may take further enforcement action depending on the circumstances, particularly where there are repeated or continuing defaults.
01
Late lodgment penalty
The applicable penalty is imposed when the overdue Annual Return is filed.
02
Composition may be offered
ACRA may offer a composition sum instead of proceeding with prosecution. Its current guidance states a minimum composition sum of S$500 for each breach in the examples described.
03
Court prosecution is possible
ACRA may prosecute the company and its directors if a composition is not accepted, there are multiple or repeated late filings, or ACRA decides not to offer composition.
04
Repeated offences can have wider consequences
ACRA’s guidance also describes director disqualification and striking-off consequences in specified circumstances.
Received an ACRA court summons?
A court summons should be treated as an urgent compliance matter. ACRA’s published process explains that the company representative or director may need to attend court, even while an appeal is being processed. Failure by a director to attend can lead to a warrant of arrest.
Important: An audit firm can help complete the audit and supporting compliance work, but it does not replace legal advice or legal representation. Directors facing prosecution or a court hearing should consider obtaining advice from a qualified Singapore lawyer.
If the company’s financial statements still require audit, the practical priority is usually to establish what is outstanding, whether the accounting records are ready and how quickly an audit can realistically be completed. Do not assume that completing an audit automatically withdraws a summons; the enforcement outcome remains a matter for ACRA and the court.
What to do next
-
Confirm whether an audit is required. Check the company’s private-company status, prior-year figures and any group relationship.
-
Confirm the financial year end and filing deadline. Do not rely on last year’s calendar without checking.
-
Assess record readiness. Make sure the trial balance, financial statements and key schedules are available.
-
If overdue, disclose that at quotation stage. An auditor can only give a realistic timeline when the actual status of the records and filing position is known.
