Singapore Compliance Calendar
The Compliance Calendar Every Business Needs For Tax Filing, Payroll and Legal Obligations
Compliance in Singapore is not optional. Whether you are running a lean startup or managing a regional head office, every business must navigate the legal, tax and operational obligations set out by Singapore’s corporate framework. From the moment a company is incorporated, directors must ensure that filings, contributions and taxes are done accurately and on time.
This article outlines the essential tasks every company must perform throughout the financial year. It also explains why a personalised compliance calendar is one of the most effective tools for maintaining oversight and avoiding penalties.
The Compliance Calendar: A Tool for Accuracy and Efficiency
Every company in Singapore, regardless of size or structure, has key responsibilities tied to its financial year end (FYE). These include declaring income, paying tax, holding AGMs and making statutory filings with ACRA and IRAS.
While many assume these deadlines are fixed to the calendar year, that is incorrect. Singapore allows companies to select their own financial year end (FYE), meaning most compliance requirements are dynamic and must be calculated in relation to that date. This is why a compliance calendar tailored to your company’s dates is critical. It allows directors, accountants and HR managers to track filing obligations with clarity.
Late submissions for tax, ECI, CPF or the annual return can result in penalties, enforcement actions or audit risks.
Singapore Company Tax Filing and ECI Deadlines
The Inland Revenue Authority of Singapore (IRAS) requires every company to file an Estimated Chargeable Income (ECI) within three months of its financial year end (FYE). Even if the company has no taxable income, a zero ECI is still required unless a waiver applies.
For a more detailed explanation of how ECI is calculated and how to determine your company’s chargeable income, you can refer to our dedicated article here.
The Form C-S or Form C must then be submitted within eleven months after the FYE. This submission forms the basis for Singapore company tax, which is currently levied at a flat rate of 17 percent on chargeable income.
Small companies eligible for Form C-S or Form C-S Lite must file their corporate income tax returns electronically via the myTax Portal on IRAS and retain supporting records for at least five years, in accordance with IRAS record-keeping requirements.
You may also find our in-depth guide on Corporate Tax in Singapore helpful, which outlines the filing process, exemptions and key changes to look out for each year.
Failing to file on time can lead to estimated assessments or enforcement actions. IRAS has the legal right to impose a composition fine of up to SGD $1,000 for non-compliance, and repeated offences may result in court summons.

ACRA Annual Return, AGM and Company Governance
Singapore-incorporated companies must hold their Annual General Meeting (AGM) within six months of their financial year end (FYE) unless exempt under the Companies Act. At the AGM, directors present the company’s financial statements to shareholders for approval.
Companies incorporated in Singapore are also required to file their annual returns with the Accounting and Corporate Regulatory Authority (ACRA) within seven months after their FYE to ensure the company’s information on the public register is current. Failure to do so may result in enforcement action or penalties. Read more about annual returns here.
According to ACRA’s public enforcement notices, hundreds of companies are penalised each year for not filing annual returns.
We explain how ACRA handles persistent filing failures, including common oversights that lead to penalties, in our article: Navigating Compliance: How Not to End Up in ACRA’s Naughty Corner
The compliance calendar should incorporate these governance milestones. Directors are personally liable for failure to comply and should ensure that meeting minutes, resolutions and financial statements are prepared and approved in time.

Monthly Payroll, CPF and SDL in Singapore
If your company has employees, monthly obligations form a significant part of compliance in Singapore. This includes calculating and contributing to the Central Provident Fund (CPF) for eligible employees.
You can read a fuller breakdown of payroll processes, CPF contributions and SDL obligations in our detailed article: Payroll in Singapore.
CPF contributions must be submitted by the 14th of each month. Failure to do so may result in enforcement action and late payment interest of 1.5 percent per month, beginning from the day after the due date. The CPF Board publishes its submission deadlines and enforcement policies here.
In addition to CPF, employers must pay the Skills Development Levy (SDL). While often overlooked, SDL in Singapore is mandatory. The levy funds workforce training and development, and is payable even for staff earning below CPF thresholds. The current rate is 0.25 percent of monthly remuneration, with a minimum of SGD 2 and a maximum of SGD 11.25 per employee. SDL is collected alongside CPF contributions.
Ensure your compliance calendar includes monthly CPF and SDL calculations, submissions and payments. This is particularly important for businesses with fluctuating headcounts, casual staff or seasonal employment.
IR8A and Employee Income Reporting
By 1 March each year, employers must submit IR8A forms for all employees earning more than SGD $22,000 per annum. This includes directors and all full-time and part-time staff.
This obligation supports Singapore’s Auto-Inclusion Scheme for income reporting to IRAS. Non-compliance can result in financial penalties and reputational risk.
The tax filing deadline for IR8A is static, unlike most corporate requirements tied to the FYE. It should appear in every company’s compliance calendar regardless of business size.
Data Protection and Legal Accountability
Statutory compliance also includes non-financial obligations. Every organisation in Singapore must appoint a Data Protection Officer (DPO) under the Personal Data Protection Act (PDPA).
Companies are legally accountable for breaches of personal data and must implement internal policies, staff training and breach notification protocols. In 2023, the Personal Data Protection Commission (PDPC) issued over SGD 1 million in fines to businesses for PDPA violations. You can review recent decisions via the PDPC’s enforcement summaries.
For a deeper analysis of how the PDPA applies to operational compliance and the responsibilities of a DPO, see our article: Data Accountability: A Guide to DPO and the New PDPA Penalties in Singapore.

Building a Bespoke Compliance Calendar
A tailored compliance calendar based on the company’s FYE and incorporation date is essential for managing deadlines and maintaining full compliance in Singapore across tax, filing and payroll obligations.
A compliance calendar should include:
ECI filing deadline
Tax filing deadline (Form C-S/C)
AGM and AR due dates
Monthly CPF and SDL payment dates
Annual IR8A reporting
DPO appointment and PDPA checks
A printed version can be helpful for internal reporting, especially for directors and finance teams. Digital versions can be integrated into team calendars and email reminders. IRAS provides a Company Start-Up Kit to understand your first filing obligations with IRAS and ACRA.
When we incorporate companies, we provide each client with a personalised compliance calendar aligned to their financial year end and incorporation date. This ensures that key statutory milestones, and tax filing deadlines are clearly mapped from the outset, reducing risk and allowing directors to focus on building the business with confidence.
