Starting a Business in Singapore: What to Do After Company Incorporation

Executive Summary

Starting a business in Singapore involves more than registering a company with ACRA. After incorporation, a private limited company must manage ongoing obligations involving corporate secretarial compliance, accounting records, annual returns, corporate income tax and, where applicable, GST, payroll and CPF contributions.

Key requirements include appointing a company secretary within six months, maintaining proper statutory and financial records, and meeting filing deadlines based on the company’s financial year-end. Some businesses also require licences, employee-related registrations and additional governance arrangements. Establishing these processes early can reduce compliance risks and support sustainable operations. BESO provides Singapore companies with incorporation, corporate secretarial, accounting, taxation and payroll services throughout their business journey.

What Happens After Incorporating a Company in Singapore?

Company incorporation creates a legal business entity, but it does not complete all the administrative and regulatory requirements needed to operate that business.

Once a private limited company is successfully registered with the Accounting and Corporate Regulatory Authority (ACRA), its directors must ensure that the company complies with the applicable provisions of the Companies Act and other relevant Singapore laws.

These responsibilities may include appointing key officers, maintaining statutory registers, preparing accounting records, filing annual returns, meeting tax obligations and managing employment-related requirements.

The exact obligations depend on the company’s activities, financial position, employee arrangements and other circumstances.

For official guidance, see ACRA’s post-registration guide for local companies.

1. Review Your Company’s Incorporation Documents

After successful incorporation, review the company’s registration information and documents.

These may include:

• Unique Entity Number (UEN).
• Company name and registered office address.
• Company constitution.
• Directors and shareholders’ particulars.
• Share capital and shareholding information.
• Financial year-end.
• Registered business activities.

Confirm that the information is accurate and consistent with the intended business arrangements.

ACRA provides a complimentary Business Profile after successful registration, subject to the applicable download period.

Companies should also establish appropriate access to government digital services, including Corppass where required.

2. Appoint a Company Secretary Within Six Months

Every Singapore company must appoint a company secretary within six months of incorporation.

The company secretary supports the company’s compliance with applicable statutory and administrative requirements.

Common responsibilities include:

• Maintaining statutory registers and records.
• Preparing relevant board and shareholder resolutions.
• Supporting annual general meeting requirements.
• Assisting with ACRA annual return filings.
• Updating registered company information when required.
• Maintaining records of relevant corporate decisions.

The secretary must meet the applicable qualification and residency requirements.

A sole director cannot also act as the company’s sole secretary.

Official reference: ACRA’s guidance on directors and company officers.

3. Determine Whether Your Company Needs an Auditor

A Singapore company generally must appoint an auditor within three months of incorporation unless it qualifies for an audit exemption.

For example, eligible small companies may qualify for audit exemption when the relevant statutory criteria are satisfied.

However, audit exemption does not mean exemption from maintaining accounting records, preparing required financial statements or meeting other statutory obligations.

Directors should assess whether the company qualifies for exemption rather than assuming that every newly incorporated or small company is automatically exempt.

Businesses requiring assistance may explore BESO’s accounting and financial reporting services.

4. Maintain Statutory Registers and Corporate Records

Companies must maintain applicable statutory records and keep relevant information accurate.

Depending on the company, these may include:

• Register of members and shareholding information.
• Register of directors and other company officers.
• Register of registrable controllers.
• Register of nominee directors and nominee shareholders, where applicable.
• Relevant corporate resolutions and meeting records.
• Share allotment and transfer documentation.

Some information must be maintained or lodged with ACRA under specific rules and deadlines.

Changes in directors, shareholders, registered addresses and other particulars may require prompt notification through the applicable filing procedures.

Good recordkeeping supports regulatory compliance, corporate transparency and future due diligence.

5. Open a Corporate Bank Account

A corporate bank account helps separate company funds from the personal finances of shareholders and directors.

It also supports organised bookkeeping, payment processing and business financial controls.

Banks may request documents such as:

• Company Business Profile.
• Company constitution.
• Identification and verification documents for relevant individuals.
• Ownership and control information.
• Business activity details.
• Supporting information on the source of funds or intended transactions.

Bank requirements differ, and approval is subject to each institution’s due diligence and risk assessment.

Company incorporation does not guarantee bank account approval.

6. Establish Proper Bookkeeping and Accounting Records

Singapore companies must maintain proper accounting records that sufficiently explain their transactions and financial position.

Accurate records support financial reporting, tax compliance and business decision-making.

A practical bookkeeping system should cover:

• Sales invoices and customer receipts.
• Supplier invoices and payments.
• Bank transactions and reconciliations.
• Business expenses and reimbursements.
• Fixed assets and depreciation records.
• Payroll and employee-related expenses.
• Tax-related transactions.
• Other relevant supporting documentation.

Companies should generally retain accounting records for at least five years after the end of the financial year in which the relevant transactions occurred, subject to applicable legal requirements.

Why Monthly Bookkeeping Matters

Waiting until the end of the financial year to organise records can create unnecessary difficulties.

Regular bookkeeping helps businesses:

• Monitor cash flow.
• Identify unpaid invoices.
• Understand expenses.
• Prepare financial reports.
• Detect discrepancies earlier.
• Prepare for tax and statutory filings.

Explore BESO’s bookkeeping services in Singapore.

7. Understand Singapore Corporate Income Tax Requirements

Singapore companies are generally subject to corporate income tax on their chargeable income, subject to the applicable tax rules.

The headline corporate income tax rate is 17%, before relevant exemptions, rebates and adjustments.

Companies should understand two important filing obligations.

Estimated Chargeable Income (ECI)

ECI is an estimate of the company’s chargeable income for a Year of Assessment.

Companies generally must file ECI within three months after the end of their financial year unless they qualify for a filing waiver or are otherwise not required to file.

For example, the general ECI filing waiver applies when both conditions are satisfied:

• Annual revenue for the financial year is S$5 million or below.
• ECI for the relevant Year of Assessment is nil.

See IRAS’s ECI filing guidance.

Corporate Income Tax Return: Form C-S, Form C-S (Lite) or Form C

Companies generally must file the applicable corporate income tax return by 30 November each year, unless a filing waiver or another exception applies.

The correct return depends on the company’s eligibility and circumstances.

These tax filings are separate from the annual return filed with ACRA.

See IRAS’s corporate income tax filing guidance.

For assistance, explore BESO’s corporate tax filing services.

8. Check Whether GST Registration Is Required

Not every newly incorporated Singapore company must immediately register for Goods and Services Tax (GST).

GST registration depends on the applicable rules, including the business’s taxable turnover.

Under the general compulsory registration framework, GST registration may be required when:

• Taxable turnover exceeds S$1 million under the retrospective test at the end of a calendar year; or
• The business can reasonably expect taxable turnover to exceed S$1 million in the next 12 months under the prospective test.

Different application deadlines apply to these tests, and special rules may apply in certain circumstances.

Businesses below the compulsory threshold may consider voluntary GST registration, subject to the applicable conditions.

GST-registered businesses must also comply with invoicing, recordkeeping, return filing and payment obligations.

For official guidance, see IRAS’s GST registration requirements.

BESO also provides GST registration and taxation services.

9. Obtain the Necessary Business Licences and Permits

ACRA incorporation does not automatically authorise a company to carry out every regulated business activity.

Depending on the business, separate licences or approvals may be required.

Examples include:

• Food and beverage operations.
• Employment agency services.
• Financial services.
• Healthcare activities.
• Regulated education services.
• Certain transport and logistics activities.

Importers and exporters may also need to complete relevant Customs registration and permit procedures.

Business owners should confirm licensing requirements before commencing regulated activities.

Use GoBusiness Singapore to explore relevant government licences and permits.

10. Set Up Payroll, CPF and HR Administration

Companies hiring employees in Singapore must comply with applicable employment laws and payroll obligations.

These responsibilities may include:

• Preparing employment contracts and key employment terms.
• Maintaining employment records.
• Calculating and paying salaries on time.
• Issuing itemised payslips where required.
• Computing CPF contributions for eligible employees.
• Paying the Skills Development Levy where applicable.
• Managing leave and other statutory entitlements.
• Meeting applicable employee income reporting requirements.

CPF Contributions

Employers must generally contribute CPF for eligible Singapore Citizen and Singapore Permanent Resident employees.

Contribution rates depend on factors such as age, residency status and applicable wages.

CPF contributions are due on the last day of the calendar month. Enforcement action may apply if payment is not made by the 14th of the following month, or the next working day where applicable.

Employers should obtain a CPF Submission Number where required.

See CPF Board’s employer contribution guidance.

Payroll and Employee Administration

A reliable payroll process helps companies calculate wages, deductions, CPF contributions and other relevant payments accurately.

Businesses should also consider applicable requirements involving the Employment Act, work passes, employee tax reporting and personal data protection.

Explore BESO’s employee payroll services.

11. Understand ACRA Annual Returns and AGM Requirements

Singapore companies must comply with applicable annual filing and meeting requirements.

Annual General Meeting (AGM)

For a typical private company, an AGM is generally required within six months after the financial year-end unless the company qualifies for an exemption or validly dispenses with the AGM under the Companies Act.

The relevant requirements should be assessed based on the company’s circumstances.

Annual Return Filing

Non-listed Singapore companies generally must file their annual return with ACRA within seven months after the financial year-end.

Different deadlines may apply to certain company categories, including companies with an overseas branch register.

An annual return is not the same as a corporate income tax return.

Even dormant or inactive companies generally remain subject to ACRA annual return requirements unless a specific exception applies.

Official reference: ACRA’s annual return deadlines and requirements.

12. Establish Corporate Governance and Internal Controls

Corporate governance involves the systems, responsibilities and procedures through which a company is directed and controlled.

Good governance is not limited to large listed companies.

Small and medium-sized businesses can also benefit from clear decision-making and financial controls.

Practical measures may include:

• Clearly defining directors’ and management responsibilities.
• Documenting significant business decisions.
• Maintaining appropriate approval procedures.
• Separating personal and company expenditure.
• Monitoring related-party transactions.
• Reviewing financial reports regularly.
• Protecting confidential business information.
• Maintaining accurate statutory and ownership records.

Directors remain responsible for their statutory duties even when administrative functions are outsourced.

Explore BESO’s corporate governance services.

Important Statutory Deadlines for Singapore Companies

The following table summarises common deadlines for an ordinary non-listed private limited company.

Requirement	General Deadline	Responsible Authority
Appoint company secretary	Within 6 months of incorporation	ACRA
Appoint auditor, unless exempt	Within 3 months of incorporation	ACRA
AGM, unless exempt or dispensed with	Generally within 6 months after FYE	ACRA
Annual return	Generally within 7 months after FYE	ACRA
ECI	Within 3 months after FYE unless waived or exempt	IRAS
Form C-S / C-S (Lite) / C	Generally 30 November each year	IRAS
CPF contributions	Due at month-end; enforcement after the 14th of the following month, subject to working-day rules	CPF Board
GST return, if registered	Generally within 1 month after the prescribed accounting period	IRAS

Actual deadlines depend on the company’s classification, financial year-end and eligibility for exemptions or alternative requirements.

Example: Compliance Calendar for a Company With a 31 December Financial Year-End

Consider a typical non-listed private company with a financial year ending on 31 December.

Its general compliance calendar may include:

Period	Illustrative Requirement
By 31 March of the following year	ECI filing, unless waived or exempt
By 30 June of the following year	AGM, where required
By 31 July of the following year	ACRA annual return
By 30 November in the relevant Year of Assessment	Applicable corporate income tax return
Monthly	Bookkeeping, payroll and CPF where applicable
Throughout the year	Statutory record updates and regulatory compliance

This is an illustration only. The relevant Year of Assessment, first-year filing rules and specific company circumstances must be considered when preparing an actual compliance calendar.

What Happens If a Singapore Company Misses Its Compliance Deadlines?

Late or inaccurate compliance filings can expose a company and, in some cases, its officers to consequences under applicable law.

Potential consequences include:

• Late filing penalties.
• Composition sums or enforcement action.
• Additional administrative costs.
• Interest on overdue statutory payments.
• Problems during financing or due diligence.
• Increased regulatory scrutiny.
• Personal consequences for directors or officers in certain circumstances.

The consequences depend on the specific obligation and the nature of the non-compliance.

Companies should address missed deadlines promptly and seek appropriate assistance where necessary.

Common Post-Incorporation Mistakes to Avoid

1. Assuming Incorporation Completes All Legal Requirements

Registration creates the company, but ongoing statutory, tax and operational requirements continue after incorporation.

2. Delaying the Appointment of a Company Secretary

The six-month appointment deadline should be monitored from the date of incorporation.

3. Mixing Personal and Company Finances

Using personal accounts for company transactions can complicate bookkeeping, tax reporting and financial controls.

4. Neglecting Bookkeeping Until Year-End

Delayed bookkeeping may result in missing records, inaccurate financial information and avoidable filing difficulties.

5. Confusing ACRA and IRAS Filings

ACRA annual returns and IRAS corporate income tax returns are separate obligations with different deadlines.

6. Ignoring GST Registration Requirements

Businesses should monitor taxable turnover and determine whether compulsory registration rules apply.

7. Missing Payroll and CPF Deadlines

Employers must ensure salaries, CPF contributions and related employment obligations are handled correctly.

8. Failing to Update Company Information

Changes to company officers, ownership or other registered particulars may require notifications or filings within prescribed periods.

How to Build a Strong Operational Foundation After Incorporation

A practical post-incorporation plan should combine regulatory compliance with sound business administration.

First 30 Days

• Review incorporation documents and company particulars.
• Confirm access to relevant government services.
• Begin corporate bank account arrangements.
• Identify required licences and permits.
• Establish bookkeeping procedures.
• Confirm responsibility for statutory filings.

First 90 Days

• Confirm whether an auditor must be appointed within the statutory timeframe.
• Review company secretarial arrangements.
• Establish internal financial controls.
• Review tax and GST obligations.
• Set up payroll and CPF processes if employees are hired.
• Prepare an initial compliance calendar.

First Six Months

• Ensure a company secretary has been appointed within the required period.
• Review the accuracy of statutory registers.
• Monitor accounting records and cash flow.
• Review changes in business activities or ownership.
• Prepare for future financial reporting and annual filing requirements.

Ongoing Operations

• Maintain accounting records regularly.
• Review tax obligations and filing deadlines.
• Monitor GST registration requirements.
• Maintain accurate payroll and employment records.
• Update company particulars when required.
• Review corporate governance procedures.

Should You Outsource Corporate Compliance, Accounting and Payroll?

Some businesses manage their administrative responsibilities internally, while others outsource selected functions to professional service providers.

Outsourcing may be worth considering when:

• The company has limited internal administrative resources.
• Directors are unfamiliar with Singapore filing requirements.
• Accounting transactions are becoming more complex.
• The business is hiring employees.
• The company operates across multiple jurisdictions.
• Management prefers to focus internal resources on core business activities.

However, outsourcing does not transfer all legal responsibilities away from the company or its directors.

Businesses should maintain appropriate oversight of outsourced services and ensure that information provided to service providers is complete and accurate.

Frequently Asked Questions About Starting a Business in Singapore

1. What should I do immediately after incorporating a company in Singapore?

Review your incorporation documents, confirm company particulars, establish banking and accounting arrangements, check licensing requirements, arrange company secretarial support and prepare a compliance calendar. Additional steps depend on the company’s activities and employees.

2. Is a company secretary compulsory for a Singapore private limited company?

Yes. Every Singapore company must appoint a company secretary within six months of incorporation. The secretary must satisfy the applicable legal requirements, and a sole director cannot also act as the company’s sole secretary.

3. Does a new Singapore company need to file tax returns if it has no profit?

A company may still have tax filing obligations even if it has no taxable profit. Whether ECI or an annual corporate income tax return is required depends on the applicable waiver and filing rules. Companies should check IRAS requirements rather than assuming that no profit means no filing.

4. Does every Singapore company need to register for GST?

No. GST registration generally depends on taxable turnover and other applicable rules. Under the general compulsory registration framework, a business must assess whether its taxable turnover exceeds S$1 million under the retrospective or prospective test. Some businesses may register voluntarily, subject to conditions.

5. Can a Singapore company outsource accounting, tax filing and corporate secretarial work?

Yes. Companies can engage professional service providers for accounting, tax compliance, corporate secretarial services and payroll administration. However, directors remain responsible for fulfilling their statutory duties and should maintain appropriate oversight.

Conclusion: Incorporation Is the Beginning of Your Business Journey

Starting a business in Singapore involves more than completing an ACRA registration.

Once incorporated, a company must maintain appropriate statutory records, financial information, tax compliance, employment administration and corporate governance procedures.

By understanding these requirements early, business owners can reduce avoidable administrative problems and establish a stronger foundation for their operations.

Whether a company is newly incorporated or already expanding, reliable corporate administration remains an important part of sustainable business management.
