Singapore · Taxation & Audit
Singapore is known for a low tax rate and territorial taxation: corporate income tax is 17%, Goods and Services Tax (GST, i.e. VAT) is 9%, with no capital-gains tax and exempt dividends. From 2025, the global minimum tax (IIR+DTT) applies; MNE groups with global revenue ≥€750m must top up to a 15% effective rate.
Key points
- Corporate income tax: flat 17%; for the first 3 years, the first S$100k of taxable income is 75% exempt, the next S$190k is 50% exempt.
- GST (VAT): standard rate 9% (raised from 8% in 2024); registration required when annual taxable supply exceeds S$1m.
- Territorial taxation: foreign-sourced dividends and branch profits are generally not taxed (subject to conditions).
- Global minimum tax: from 2025, groups with global revenue ≥€750m are subject to IIR (parent top-up) and DTT (low-tax jurisdiction top-up); the gap to 15% effective rate must be topped up.
- Transfer pricing: must follow OECD guidelines and prepare contemporaneous documentation.
Procedure
- Register the tax number with IRAS within 30 days of incorporation or before business commences.
- Register for GST upon hitting the threshold.
- After fiscal year-end, prepare financial statements (under SFRS).
- Audit: 'small company' exemption available if criteria met (revenue ≤S$10m, assets ≤S$10m and employees ≤50).
- Annual filing: corporate income tax return (YA), AGM and Annual Return (ACRA).
- MNE groups should assess global minimum tax impact and prepare the GloBE information return.
Hard requirements
- Engage a local bookkeeping or tax agent.
- Meet economic-substance requirements (see strategy).
- Large groups must file the GloBE information return.
Costs
Accounting/audit fees by company size; government taxes paid per rules.⏱ ⏱ Timeline：Register upon incorporation; annual filing by fiscal year.⚠ Common risks
- Misusing tax exemptions leads to back-tax and fines.
- Global minimum tax erodes the value of low-tax structures (see global-min-tax topic).
- Missing transfer-pricing documentation triggers assessment adjustments.
Handbook
📘 Step-by-Step Handbook (with owner / timeline / cost / penalties)
Applies to：Annual tax compliance and filing for Singapore-incorporated companies (e.g. Pte Ltd), covering corporate income tax, GST, audit exemption and global minimum tax.
Prerequisites
- UEN (tax number) obtained.
- Local bookkeeping or tax agent engaged, or in-house finance established.
- Financial year-end date set.
- Large groups (global revenue ≥€750m) must assess Pillar Two impact.
| Step | Action | Owner | Timeline | Cost | Official form / system | Notes & penalties |
|---|---|---|---|---|---|---|
| 1 | Tax registration and bookkeeping UEN auto-serves as the tax number on incorporation; books must follow the Singapore Financial Reporting Standards (SFRS); register for GST when annual taxable supply exceeds S$1m and the threshold is met. | Company or bookkeeping agent | — | Accounting fee by company size | IRAS tax registration (auto); GST registration (within 30 days when threshold met) | GST standard rate 9% (from 2024); exports and international services are zero-rated. Penalty：Missing GST registration within 30 days of threshold draws fines |
| 2 | Audit-exemption determination Determine 'small company' exemption: revenue ≤S$10m, assets ≤S$10m and employees ≤50 (all three). If met, audit is exempted; only financial statements are prepared. | Auditor or agent | — | Audit fee (if not exempt) | Financial statements | Group member companies or public companies usually do not qualify for audit exemption. Penalty：Required-but-missing audit draws IRAS/ACRA penalties |
| 3 | Corporate income tax filing Prepare the income-tax return (Form C / C-S, small companies use C-S); flat 17%, plus the startup exemption (SUTE: first S$100k 75% exempt, next S$100k 50% exempt) or partial exemption (PTE). YA 2026 adds a 40% CIT rebate (cap S$15,000). | Company / tax agent | — | Filing service fee | IRAS Form C / C-S | Investment-holding and property-development companies are not eligible for SUTE. Penalty：Late filing draws fines; misusing exemptions draws back-tax and fines |
| 4 | GST filing If GST-registered, file GST returns per period (quarterly/monthly) and claim input credit; from 2026-04, new voluntary GST registrants must use InvoiceNow (Peppol e-invoicing). | Company / tax agent | — | None | GST F5 / e-invoice | Imported digital services fall under the Overseas Vendor Registration (OVR) regime. Penalty：Late or erroneous GST draws fines and surcharges |
| 5 | Global minimum tax (Pillar Two) assessment Groups with global revenue ≥€750m: assess IIR (parent top-up) and DTT (low-tax jurisdiction top-up) to top Singapore entities up to 15% effective rate; prepare the GloBE information return. | Group tax / Big Four | — | Advisory and filing fees high | GloBE information return (IRAS) | In force from 2025, eroding traditional low-tax concessions. Penalty：Non-compliant top-up draws back-tax and penalties |
| 6 | Transfer pricing and Annual Return alignment Cross-border related-party transactions must follow OECD guidelines with contemporaneous documentation; simultaneously complete the ACRA Annual Return. | Company / agent | — | Service fee | Transfer-pricing documentation; Annual Return | Economic-substance requirements run throughout. Penalty：Missing transfer-pricing documentation draws adjustment and back-tax |

⚠ Common pitfalls
Misusing the startup exemption (SUTE)影响：Investment-holding/property companies misapply it → back-tax + fine规避：Strictly check SUTE's four conditions (incorporation place / tax residency / ≤20 shareholders / ≥10% individual shareholders)
GST threshold exceeded without registration影响：Fines and retrospective back-tax规避：Monitor the 12-month rolling turnover; register within 30 days of hitting S$1m
Missing transfer-pricing documentation影响：Adjusted and back-taxed by IRAS规避：Retain pricing policy and contemporaneous docs for cross-border related-party deals
Global minimum tax erodes low-tax concession影响：Large groups must top up to 15% effective rate规避：Run GloBE impact assessment and entity-level top-up planning early
Late filing影响：Compounding fines规避：Build an annual compliance calendar; delegate tracking to an agent
