Running a construction business in Singapore is rewarding, but the regulatory landscape is one of the most demanding of any industry. Construction companies must satisfy obligations across at least four government agencies — ACRA, BCA, MOM, and IRAS — and failure to comply with any one of them can result in fines, licence revocations, or debarment from public contracts.

This guide sets out the key compliance requirements for Singapore construction companies in 2026, what deadlines to watch, and how to structure your corporate housekeeping so that nothing falls through the cracks.

1. ACRA: Corporate Compliance for Construction Companies

Every construction business operating in Singapore must first be registered with the Accounting and Corporate Regulatory Authority (ACRA). Most contractors operate as private limited companies (Pte Ltd), which limits personal liability and is a prerequisite for most BCA contractor registration grades.

Annual Filing Obligations

As a Singapore-incorporated company, you must:

  • Hold an Annual General Meeting (AGM) within six months of your financial year-end (for private companies that have not dispensed with the AGM requirement).
  • File an Annual Return (AR) with ACRA within seven months of your financial year-end. The AR includes your company’s financial statements (for non-exempt companies) and the latest particulars of directors, shareholders, and the registered address.
  • Maintain a Register of Registrable Controllers (RORC) and lodge it with ACRA. Failure to maintain accurate records of beneficial owners carries penalties of up to S$5,000 per officer.

Companies with annual revenue below S$500,000 (or that meet the Small Company criteria under the Companies Act) may qualify for audit exemption. However, you still need to prepare financial statements that comply with Singapore Financial Reporting Standards.

2. BCA: Contractor Registration and Licensing

Any company that tenders for construction works — including building, civil engineering, and specialist works — must be registered with the Building and Construction Authority (BCA) under the Contractors Registration System (CRS).

Contractors Registration System (CRS)

The CRS classifies contractors into workheads and grades based on financial capacity, track record, and key personnel qualifications:

  • General Builder Licence (GBL): Required for any company carrying out general building works. GBL Class 1 is for projects of any value; GBL Class 2 covers projects up to S$6 million.
  • Specialist Builder Licence (SBL): Required for specialist trades such as piling, prestressing, structural steelwork, and waterproofing.
  • CRS Grades (CW/ME/CR Workheads): Contractors tendering for public sector projects must hold the appropriate workhead grade, which determines the maximum tender value they may bid for.

BCA assesses financial capacity based on your company’s paid-up capital, net worth, and annual turnover, as reported in your audited or unaudited accounts. A weak financial position can lead to downgrading or suspension of your registration — making timely and accurate accounts crucial.

Renewal and Upgrading

CRS registration must be renewed every three years. Companies seeking to upgrade their grade must demonstrate improved financial standing and additional qualifying projects. Maintain well-organised project records and financial statements throughout the year, not just at renewal time.

3. MOM: Workplace Safety and Foreign Worker Compliance

The Ministry of Manpower (MOM) regulates both workplace safety and the employment of foreign workers in Singapore’s construction sector. These are among the most heavily enforced areas of construction compliance.

Workplace Safety and Health (WSH)

Under the Workplace Safety and Health Act, construction companies must:

  • Appoint a Workplace Safety and Health (WSH) Officer if the contract value of the construction project exceeds S$10 million.
  • Register as a Principal Contractor with MOM for projects above S$30 million.
  • Conduct risk assessments before any construction activity and implement appropriate safety measures.
  • Ensure that all workers hold the requisite Construction Safety Orientation (CSO) card (also known as the “Green Card”) before entering worksites.
  • Comply with the BizSAFE programme, which is a prerequisite for government projects and increasingly required by private main contractors.

MOM conducts unannounced inspections of construction sites. Companies found to have violated WSH requirements can face stop-work orders, fines of up to S$500,000, and criminal prosecution of responsible officers.

Foreign Worker Quotas and Levies

Construction is one of the sectors that may employ Work Permit holders from approved source countries. However, the number of foreign workers is strictly capped by the Man-Year Entitlement (MYE) system for project-based workers, and by the Dependency Ratio Ceiling (DRC) for company-based hires.

As at 2026, the DRC for the construction sector allows up to a 1:1 ratio of foreign workers to local workers (i.e., one foreign worker per local employee). Employers must also pay monthly Foreign Worker Levies (FWL) — the levy rate varies depending on the worker’s skill tier and whether the company meets the higher-skilled proportion requirement.

For more details on managing foreign worker applications and levy rates, see our Work Permit Application service page.

4. IRAS: Tax Obligations for Construction Companies

Construction companies in Singapore are subject to Singapore’s corporate income tax and, if their turnover crosses the threshold, goods and services tax.

Corporate Income Tax (CIT)

Singapore’s headline corporate tax rate is 17%. However, construction companies can significantly reduce their effective tax rate through:

  • Capital Allowances: Machinery, equipment, and qualifying renovation expenditure may qualify for accelerated capital allowances, allowing faster write-offs against taxable income.
  • Section 14Q Renovation Deduction: Qualifying renovation and refurbishment costs may be deducted over three years.
  • Productivity Solutions Grant (PSG): Grants for adopting approved technology solutions can reduce costs and are generally non-taxable.
  • Start-Up Tax Exemption / Partial Tax Exemption: New companies receive full exemption on the first S$100,000 of chargeable income (capped at three years). All companies benefit from the partial exemption framework thereafter.

Estimated Chargeable Income (ECI) must be filed with IRAS within three months of your financial year-end. Corporate income tax returns (Form C or Form C-S/C-S Lite) are due by 30 November each year for the preceding Year of Assessment.

GST Registration

If your company’s annual taxable turnover exceeds S$1 million, you must register for GST. Construction contracts are generally standard-rated (9% GST). However, cross-border contracts and certain export-related services may be zero-rated.

GST-registered companies must file GST returns quarterly and maintain proper tax invoices for all supplies made and received. See our GST Registration service page for guidance on the registration process.

5. CPF Contributions

For Singapore citizens and permanent residents employed by your construction company, CPF contributions are mandatory. The combined employer-employee contribution rate varies by age — employees under 55 attract the highest rates. Contractors and subcontractors must be careful to correctly classify workers as employees (subject to CPF) versus self-employed persons (not subject to CPF for employer).

Misclassification of workers is a common area of MOM enforcement action. If workers are found to be employees rather than independent contractors, the company can be required to make retrospective CPF contributions with interest and penalties.

6. Key Compliance Calendar for 2026

  • Ongoing: MYE and DRC compliance, FWL payment (monthly), WSH incident reporting (24 hours for dangerous occurrences).
  • Within 3 months of FYE: File ECI with IRAS.
  • Within 6 months of FYE: Hold AGM (if required).
  • Within 7 months of FYE: File Annual Return with ACRA.
  • 30 November 2026: Corporate income tax return (Form C/C-S) due for YA2026.
  • Every 3 years: BCA CRS renewal.
