TAX SERVICES SINGAPORE
Corporate Tax Services In Singapore – Trusted IRAS-Compliant Filing With Peace of Mind
Our corporate tax services help businesses meet tax compliance obligations, manage tax risks, and make informed decisions that support business operations and growth. Singapore operates under a self-assessment system regulated by the Inland Revenue Authority and strict tax regulations, where every company is responsible for the accuracy of its income tax returns, filing, and compliance with tax law.
Businesses in Singapore pay corporate tax at a flat rate of 17% on profits, and there is no capital gains tax. However, incorrect application of rules, poor accounting adjustments, or non-compliance can result in heavy penalties, additional taxes, and unnecessary costs. Our tax professionals are well-versed in Singapore tax, ensuring compliance requirements are met across each financial year.
Corporate Tax Isn’t Just Compliance — It’s a Risk You Must Control
Our tax services include the preparation and filing of annual income tax returns, the filing of Estimated Chargeable Income, and the computation of tax liabilities for Singapore-registered companies. Returns may be prepared manually or using tax preparation software, including connected services such as the myTax Portal.
We assist clients by ensuring the timely filing of Form C and Form C-S, the accurate calculation of taxable income from accounting profit, and the proper treatment of expenses, transactions, payroll, and income tax adjustments. Adequate tax compliance protects businesses from penalties and supports confidence at the director and management level.
Where Most Companies Quietly Get Exposed
Many businesses believe their corporate tax is “handled” because returns are filed on time using manual methods or tax preparation software. In reality, this creates a false sense of security. Hidden tax risks often sit beneath the surface—especially where complex issues, cross-border transactions, or international tax exposure are involved.
Companies typically face these problems:
- Corporate tax is treated as a mechanical compliance exercise
- Heavy reliance on junior staff instead of experienced tax professionals
- Missed tax exemption scheme benefits and incentives
- Weak documentation for income, expenses, payroll, and transactions
- Transfer pricing and cross-border tax risks are overlooked
- Directors signing Form C or Form C-S filings without confidence
These issues rarely show up immediately. They surface only when IRAS initiates audits or reviews—forcing businesses into reactive explanations, corrections, and unnecessary costs.
What Confident Companies Actually Want
Companies do not want cheap filing. They want certainty, control, and confidence—mainly when corporate tax directly affects profits, costs, employees, and long-term growth.
Businesses want to operate with:
Confidence that income tax returns are accurate and fully compliant
Clear ownership from well-versed tax professionals
Predictable timelines and timely filing to avoid penalties
Strong documentation that stands up to tax authorities
Reduced tax risks and fewer surprises
Corporate tax at this stage feels calm, repeatable, and under control—not stressful or uncertain.
The System That Moves You From Risk to Control
We bridge the gap between risk and control by changing how corporate tax is managed, not just how it is filed. Our approach combines tax compliance and tax advisory to support both daily business operations and strategic decision-making. Our experienced tax professionals take responsibility for tax positions, tax planning strategies, and compliance requirements.
Proactive Risk and Leakage Review
We review accounting income, expenses, and transactions to ensure taxable income is correctly derived and aligned with IRAS rules. This identifies tax risks, missed incentives, and exposure areas early—before penalties arise.
Defensible Documentation
We prepare contemporaneous documentation to support Form C, Form C-S, and income tax returns at the point of filing, not after problems surface. When IRAS raises queries, responses are consistent, prompt, and fully supported.
Structured Accountability and Review
Every corporate tax engagement undergoes a layered technical review and senior sign-off. This ensures compliance with requirements and allows directors to sign filings with confidence.
Technology-Enabled Workflows
We use connected services and cloud-based accounting tools to manage documents, payroll data, approvals, and filing deadlines efficiently. Technology improves accuracy and speed, while professional judgment determines tax outcomes.
The Outcome You Can Stand Behind
After the transformation, corporate tax becomes a controlled system, not a recurring risk. Companies move from uncertainty and reactive fixes to confidence, clarity, and defensible compliance—year after year.
WE HANDLE THE COMPLIANCE SO YOU CAN RUN YOUR BUSINESS WITH CLARITY AND CONFIDENCE
Know Your Deadlines. Control Your Tax Risks.
File With Confidence.
Singapore operates under a self-assessment system regulated by the Inland Revenue Authority of Singapore (IRAS). Corporate tax compliance carries fixed filing deadlines and director-level accountability. Missed deadlines or inaccurate income tax returns can result in penalties, additional assessments, and scrutiny from tax authorities.
Key corporate tax compliance deadlines include:
- Filing of Estimated Chargeable Income (ECI) within three months from the end of the financial year
- Eligible companies enrolled in GIRO may pay corporate tax in up to 10 instalments, improving cash flow
- Annual filing of Form C or Form C-S by prescribed IRAS deadlines
- Timely responses to IRAS queries, reviews, or audits
Engaging our tax professionals ensures corporate tax services are delivered with structure and accountability. Clients receive:
- Accurate tax computations aligned with Singapore tax regulations
- Timely preparation and e-filing of Form C and Form C-S
- Proper supporting documentation prepared at the point of filing
- Clear visibility over deadlines, responsibilities, and next steps
The outcome is reduced tax risks, fewer last-minute issues, and confidence that filings are defensible—allowing management to focus on daily operations and growth.
How We Take Ownership of Your Corporate Tax
Our experienced tax professionals provide tax advisory services across a broad range of tax disciplines, including corporate services, services tax, international tax, and transfer pricing. We help businesses manage tax implications, risks, and complex issues related to cross-border transactions and multiple tax authorities across the Asia Pacific region.
Our services are tailored to specific industries and business needs, helping companies resolve business issues while staying up to date with changing tax rules. We provide comprehensive tax solutions that create value, protect wealth, and drive growth.
Compliance Where It’s Required.
Advisory Where It Creates Value.
Tax services are categorized into compliance and advisory functions. We support both. Our team assists taxpayers in meeting compliance requirements while applying lawful strategies, such as the tax-exemption scheme, start-up incentives, and other planning opportunities, to reduce tax costs and optimize outcomes.
Failure to manage tax obligations correctly can lead to audits, penalties, and disruption to daily operations. Our professionals assist with managing IRAS communications, audits, and investigations, acting as representatives for taxpayers and preparing the required documentation.
Beyond Filing: Supporting Your Business as It Grows
In addition to corporate tax services, we support businesses with income tax, payroll, and employee-related tax matters. Our Personal Tax team assists companies and employees with personal income tax returns, relief claims, and resident and non-resident tax matters in line with Singapore law and filing dates.
We also assist with Goods & Services Tax matters, including GST registration, quarterly GST returns, and advisory on GST treatment. Businesses without internal GST knowledge face a high risk of non-compliance and penalties.
