Essential Business Operations Every Singapore SME Must Set Up

Last Updated: June 2026

Right after you incorporate a Singapore company, set up two things in parallel: the statutory and compliance items the law requires, and the operational items the business needs to actually run. On the statutory side, appoint a company secretary within 6 months, keep a registered local office address, and diarise your compliance calendar (ECI within 3 months of your financial year end, AGM within 6 months, annual return within 7 months, corporate tax e-Filed by 30 November). On the operational side, open a corporate bank account, put an accounting system in place, sort out CPF and payroll if you hire, and arrange insurance. This guide walks through the full essential business operations Singapore checklist a new SME must put in place.

Key Takeaways

• Appoint a company secretary within 6 months of incorporation, and keep a registered local office address that is a real address, not a P.O. box.
• Diarise the core compliance calendar from your financial year end: ECI within 3 months, AGM within 6 months, annual return within 7 months, and corporate tax e-Filed by 30 November.
• Open a corporate bank account and set up an accounting and bookkeeping system from day one, so your records are clean before the first filing falls due.
• Register for GST only once your turnover passes S$1 million; below that it is optional.
• If you hire, handle monthly CPF contributions and payroll, and remember a company must have at least one director ordinarily resident in Singapore.
• Cosec, accounting, payroll, and the registered or virtual office can all be outsourced to one provider so the back office runs itself.

What Do You Need to Set Up After Incorporating a Company in Singapore?

Incorporation gives you a company on the register. It does not, by itself, make the company ready to trade or compliant for the year ahead. The setup work splits cleanly into two checklists that you should tackle at the same time.

The first is statutory and compliance: the obligations ACRA and IRAS impose on every active company, with fixed deadlines. The second is operational: the banking, accounting, people, and protection a business needs to function. Miss the first and you face penalties; miss the second and the business stalls. New directors should also read the wider context in our guide to the key responsibilities of a director, and if you have not incorporated yet, our walkthrough on how to register a company in Singapore covers the step before this one.

The two checklists below run in parallel. The chart maps them side by side: statutory and compliance items on the left, operational items on the right.

Statutory and Compliance Essentials

These are the items the law requires, and the ones that carry penalties if you skip them. Set them up first.

Appoint a company secretary within 6 months

Every company must appoint a company secretary within 6 months of incorporation, under section 171 of the Companies Act. The secretary keeps your statutory registers current, files with ACRA, and runs the compliance calendar. A sole director cannot also be the secretary, so most new SMEs appoint a professional firm. Our guide on why every company needs corporate secretarial services explains what the role actually does, and ACRA sets the appointment rules.

Keep a registered local office address

Your company must keep a registered office address in Singapore that is open and accessible to the public during normal office hours. It must be a real, physical address where official mail can be served, not a P.O. box. If you work from home or remotely, a registered or virtual office service gives you a compliant address without a lease. Our explainer on the registered address and virtual office setup covers how this works, and you may also need to check business licences and permits for your specific activity before you start.

Diarise the compliance calendar

The annual cycle runs from your financial year end (FYE), so you can plan it a year ahead the moment your FYE is fixed:

• File Estimated Chargeable Income (ECI) with IRAS within 3 months of your FYE, unless the waiver applies.
• Hold your Annual General Meeting (AGM) within 6 months of your FYE, unless your company is exempt or dispenses with it.
• File your annual return with ACRA within 7 months of your FYE.
• E-File your corporate income tax return with IRAS by 30 November.

ACRA and IRAS are two separate regulators on two separate portals, and filing with one does not satisfy the other. Our monthly compliance checklist breaks the full year down deadline by deadline.

Register for GST when turnover passes S$1 million

GST registration is not automatic at incorporation. You must register for GST once your taxable turnover exceeds S$1 million in a 12-month period, and you may register voluntarily below that if it suits your business. The threshold and the registration steps are explained on the IRAS GST pages, and our GST registration threshold guide covers when and how to register, including InvoiceNow.

Financial Essentials

Open a corporate bank account

A corporate bank account keeps company money separate from personal money, which matters for accounting, tax, and the limited-liability protection a company gives you. Banks now run tighter anti-money-laundering checks, so prepare your incorporation documents, director identification, and a clear description of your business before you apply. Our guide on opening a corporate bank account sets out what each bank asks for and how to speed up approval.

Set up accounting and bookkeeping

Put an accounting and bookkeeping system in place from day one. Clean records feed straight into ECI, the AGM accounts, the annual return, and the corporate tax return, so they save you scrambling at FYE. Decide early whether you will keep books in-house or outsource them, and pick software that matches your transaction volume. Our overview of accounting and compliance in Singapore explains what good bookkeeping covers and how it links to your filings.

People Essentials

If you hire staff, two duties kick in straight away. First, you must make monthly CPF contributions for your local employees by the due date, on top of running payroll correctly (salaries, itemised payslips, and IR8A at year end). Our guide on payroll services for employers covers the full employer obligations.

Second, remember the residency rule that already applied at incorporation: a company must have at least one director who is ordinarily resident in Singapore. If you are a foreign founder, you also handle work-pass and identity-verification steps, which MOM sets out, and our guide on CorpPass for foreigners explains how to access government portals without a Singpass.

Protecting the Business

Insurance is the piece new SMEs most often leave too late. Depending on your activity, you may need work injury compensation insurance if you have employees, public liability cover, professional indemnity for advisory work, or property and equipment cover. Match the policy to your real risks rather than buying the cheapest bundle. It is also worth checking your SSIC code, because the activity code you registered affects how banks and insurers assess your business.

Outsourcing Your Back Office

You do not have to build every function in-house. Cosec, accounting, payroll, and the registered or virtual office can all be outsourced, often to a single provider, so the back office runs itself while you focus on the business. For founders running lean or working remotely, this is usually cheaper than hiring and far cheaper than the penalties a missed filing brings. Our guide on how to run a remote business with virtual support services shows how the outsourced model fits together. The directors stay legally responsible either way, so choose a provider who keeps you informed.

Frequently Asked Questions

What do you need to set up after incorporating a company in Singapore?

After incorporation, set up the statutory items and the operational items in parallel. Statutory: appoint a company secretary within 6 months, keep a registered local office address, and diarise your compliance calendar (ECI within 3 months of FYE, AGM within 6 months, annual return within 7 months, corporate tax by 30 November). Operational: open a corporate bank account, set up accounting and bookkeeping, handle CPF and payroll if you hire, and arrange insurance.

When must I appoint a company secretary?

You must appoint a company secretary within 6 months of incorporation, under section 171 of the Companies Act. The secretary keeps your statutory registers up to date and handles filings with ACRA. A sole director cannot also act as the company secretary, so most new SMEs appoint a professional corporate secretarial firm to fill the role.

Do I need a corporate bank account for my company?

A corporate bank account is strongly recommended so company money stays separate from personal money, which is important for clean accounting, tax, and the limited-liability protection a company provides. Banks run anti-money-laundering checks, so prepare your incorporation documents, director identification, and a clear description of your business activities before you apply.

When must my company register for GST?

You must register for GST once your taxable turnover exceeds S$1 million in a 12-month period. Below that threshold, GST registration is voluntary and you can choose to register if it benefits your business. Once registered, you charge GST on your sales and file GST returns with IRAS on your assigned cycle.

What is the annual compliance calendar for a Singapore company?

The annual cycle runs from your financial year end (FYE). File ECI with IRAS within 3 months of FYE, hold your AGM within 6 months of FYE (unless exempt), file your annual return with ACRA within 7 months of FYE, and e-File your corporate income tax return with IRAS by 30 November. ACRA and IRAS are separate regulators, so filing with one does not satisfy the other.

Can I outsource my company’s back office?

Yes. Corporate secretarial work, accounting, payroll, and the registered or virtual office address can all be outsourced, often to a single provider, so the back office runs itself. This is usually cheaper than hiring in-house and far cheaper than the penalties a missed filing brings. The directors remain legally responsible, so choose a provider who keeps you informed of deadlines.

Get Your Back Office Set Up Right

Incorporation is the easy part. The setup that follows, the secretary, the registered address, the compliance calendar, the bank account, the books, and payroll, is what keeps your company compliant and running.
