Tax Advisory Services
Strategic tax planning and compliance services designed to optimise your tax position while ensuring full regulatory compliance with IRAS.
What We Offer
1
Corporate Tax Filing
We prepare and file your company's corporate income tax returns (Form C-S or Form C) with IRAS. Our team ensures all eligible deductions and exemptions are claimed, including the Start-Up Tax Exemption (SUTE) scheme for qualifying new companies and the Partial Tax Exemption for established businesses.
2
GST Registration & Filing
Whether you need to register for GST compulsorily (turnover exceeding S$1 million) or voluntarily, we handle the entire process. For GST-registered businesses, we prepare and file quarterly GST F5 returns, ensuring accurate calculation of output tax, input tax claims, and timely submission.
3
Tax Planning & Advisory
Our tax planning services go beyond compliance. We analyse your business structure, transactions, and growth plans to identify legitimate tax-saving opportunities. This includes advice on capital allowances, tax incentives, transfer pricing, and structuring for tax efficiency.
4
Estimated Chargeable Income (ECI)
Singapore companies must file their Estimated Chargeable Income within three months of their financial year end. We prepare and submit your ECI filing, ensuring it accurately reflects your expected taxable income and takes advantage of any applicable exemptions.
5
Personal Income Tax
For business owners and directors, we also offer personal income tax filing services. We ensure all employment income, director fees, and other taxable income are properly declared, and that all eligible reliefs and deductions are claimed. Available as an add-on for our Growth package.

IRAS Compliance & Audit Support
If your company is selected for an IRAS audit or review, our team provides full support — from preparing documentation to representing your company in discussions with IRAS. We help resolve queries efficiently and ensure a smooth audit process.
