Key Takeaways
Key accounting requirements for Singapore companies include operational tasks such as bookkeeping, payroll processing, and record keeping, as well as statutory obligations such as financial reporting, audit where required, and tax filing.
The main government bodies involved are ACRA, IRAS, and the Accounting Standards Council, each overseeing different aspects of reporting and compliance.
The accounting period for a Singapore company is its financial year, which is typically 12 months but may extend up to 18 months for the first year after incorporation.
The chosen Financial Year End determines deadlines for preparing financial statements, filing the Annual Return, and fulfilling tax obligations.
Outsourcing accounting is often the most efficient option for early stage companies, while in house accounting is more suitable for larger businesses with higher transaction volumes or complex reporting needs.
What Is Business Accounting in Singapore?
Business accounting is the process of recording, organising, and reporting a company’s financial activities so it can meet ACRA and IRAS compliance and make informed decisions.
For Singapore companies, accounting covers the full financial workflow from daily bookkeeping to annual financial reporting. It ensures that all transactions are captured accurately, classified correctly, and summarised into financial statements that reflect the company’s performance and position.
Strong accounting practices form the foundation of all compliance obligations to ACRA and IRAS and help founders understand how their business is performing.

Financial Reporting Requirements
Preparing Financial Statements
Annual financial statements are formal accounting reports that present a company’s financial performance and position for a specific financial year. For Singapore companies, preparing and filing financial statements annually is a legal requirement under the Companies Act.
Annual financial statements must be approved by the company’s Board of Directors, presented to shareholders, and filed with ACRA together with Annual Return.
For a full breakdown of requirements, exemptions, deadlines, and components of financial statements, refer to our dedicated guide on annual financial statements for Singapore companies.
XBRL Filing Requirements
XBRL, or eXtensible Business Reporting Language, is a structured digital format used to standardise the submission of financial statements in Singapore. Companies that do not fall within specific exemption categories must file their financial statements in XBRL. This format enables regulators to process and analyse financial data more efficiently than traditional PDF submissions.
For more details on XBRL filing requirements, exemptions, types of XBRL formats, and how to convert financial statements into XBRL, refer to our dedicated guide on XBRL filing in Singapore.
Audit Requirements
Most small companies in Singapore qualify for audit exemption if they meet the prescribed size criteria. A company qualifies as a small company if it satisfies at least two of the following: revenue of S$10 million or less, total assets of S$10 million or less, and no more than 50 employees. Dormant companies may also be exempt from audit.
An audit is still required for some companies due to regulatory requirements, shareholder requests, or funding needs.
For a full overview of audit thresholds and exemption rules, refer to our dedicated guide on audit requirements and exemptions in Singapore.
Accounting Standards in Singapore (SFRS & SFRS for Small Entities)
Singapore Financial Reporting Standards (SFRS)
SFRS is the main financial reporting framework in Singapore and is largely aligned with International Financial Reporting Standards. Most companies must apply SFRS when preparing their financial statements.
SFRS provides detailed guidance on recognition, measurement, and disclosure to ensure that financial statements present a true and fair view.
SFRS for Small Entities
Small private companies may use the simplified SFRS for Small Entities if they meet the qualifying criteria. This framework reduces disclosure and reporting requirements, making compliance easier for smaller businesses.
SFRS for Small Entities is suitable for companies that are not publicly accountable and meet the definition of a small entity.
Why These Standards Matter
How Accounting Helps You Stay Tax Compliant in Singapore?
Corporate Tax Filing
The corporate tax filing process for Singapore companies consists of two main steps: submitting the Estimated Chargeable Income (ECI) and filing the final Corporate Income Tax Return (Form C-S or Form C). The ECI is an early estimate of taxable profits, while the Form C-S or Form C is the final return prepared using the completed financial statements.
For a detailed explanation of ECI, Form C-S/C, tax deadlines, and the filing process, refer to our dedicated guide on corporate tax filing in Singapore.
GST Accounting
Goods and Services Tax (GST) in Singapore is a consumption tax applied to most goods and services supplied locally and to imported goods. GST registration is compulsory for businesses that exceed the S$1 million annual turnover threshold, although smaller companies may register voluntarily.
Companies registered for GST must track input and output tax, prepare periodic GST returns, and ensure that transactions are recorded accurately for compliance.
For full details on GST registration, filing, and accounting rules, refer to our dedicated guide about Singapore GST Registration.

What Is the Accounting Period in Singapore?
The accounting period refers to the period covered by a company’s financial statements and is equal to the company’s financial year.
Key points:
- It usually lasts 12 months.
- The first financial year must not exceed 18 months.
- It starts on the incorporation date or another chosen start date.
- It ends on the company’s Financial Year-End (FYE).
- It determines the basis period for financial statements and corporate tax purposes.
How to Choose the Right Financial Year-End?
The FYE is the final day of the company’s accounting cycle, typically occurring every 12 months. It does not need to follow the calendar year.
For the first financial year, the only rule is that it must not exceed 18 months. This gives new companies flexibility to set the first FYE to any date, provided the date falls within 18 months of incorporation. Every following financial year must then run for 12 months, starting immediately after the previous period ends.
Companies should select an FYE that aligns with their business cycle, operational needs, and reporting requirements.
The chosen FYE determines key statutory deadlines, including:
- Preparation of annual financial statements
- Holding the Annual General Meeting (if required)
- Filing the Annual Return with ACRA
For more guidance, refer to our dedicated guide on choosing the Financial Year-End for your Singapore company.
Common Accounting Mistakes and How to Avoid Them
Many Singapore companies encounter avoidable accounting issues that lead to compliance problems, incorrect filings, or cash flow disruptions. Below are common mistakes paired with practical steps to prevent them.
- Mixing business and personal expenses: Open a dedicated business bank account and keep all business transactions separate from personal expenses.
- Missing receipts or supporting documents: Digitise receipts immediately and store documents in organised folders or software that integrates with your accounting system.
- Poor cash flow management: Maintain a monthly cash flow forecast, invoice promptly, follow up on overdue payments, and avoid large expenditures without planning.
- Skipping monthly reconciliations: Reconcile bank, card, and payment accounts monthly to catch issues early.
- Overreliance on accounting software: Treat software as a tool, review entries manually, and schedule periodic reviews by an accountant.
- Missing compliance deadlines: Maintain a calendar of compliance deadlines, set reminders.
- Trying to handle all accounting tasks alone: Outsource accounting tasks or engage professional accounting services to ensure accuracy and compliance.
