ECI: The Essential Guide to Tax Compliance in Singapore 

Do you struggle to keep track of your company's Estimated Chargeable Income (ECI) and ensure timely compliance with tax regulations? You're not alone. Many companies face the same challenges, but with the right guidance, you can overcome these hurdles and maintain a smooth operation. Think of it as your own mission impossible—just like Ethan Hunt, with the right strategy and tools, you can succeed.

Definition of ECI and When to File It

ECI is an estimate of a company's taxable income, calculated after deducting tax-allowable expenses, for a specific Year of Assessment (YA). This estimate is crucial in determining the company's tax liability and is used as a basis for calculating the company's corporate tax.

All companies, including new ones, are required to file ECI within three months from the end of their financial year. This deadline is crucial, as companies that fail to file on time may face penalties and fines. However, companies that qualify for the administrative concession or those specifically not required to file are exempt from this requirement. Imagine you're racing against time like James Bond; timely filing is your way of avoiding traps and penalties.

Declaration of Revenue in ECI Form

When filing ECI, companies must declare their revenue, which is the main source of income. This includes income from sales, services, and investments. For investment holding companies, their main source of income will be investment income, such as interest and dividend income. If audited financial statements are not yet available, companies can refer to management accounts for the purpose of declaring revenue. It is essential to note that if the actual revenue amount based on audited financial statements differs from that declared during ECI filing, but there is no change in ECI, the revenue amount does not need to be revised.

E-Filing of ECI

From YA 2020, it is compulsory for the filing of ECI to be done electronically via the myTax Portal. This digital platform provides a secure and efficient way to file ECI, reducing the risk of errors and delays. 

To e-file ECI, companies must ensure they have been authorised as an "Approver" for Corporate Tax (Filing and Applications) in Corppass and have their Singpass and Unique Entity Number (UEN)/Entity ID.

Advantages of Filing On Time

Filing ECI on time has several advantages. Singapore-registered companies that submit their ECI within the qualifying period may opt to pay corporate taxes by instalments. This allows companies to spread their tax payments over a longer period, making it easier to manage cash flow. 

Additionally, the earlier a company files, the greater the number of instalments they will be given. This flexibility in payment terms can be a significant relief for companies, especially those with fluctuating cash flows.

Final Thoughts


In conclusion, filing ECI is a critical component of Singapore's tax system. Companies must ensure they file their ECI on time to avoid penalties and fines. The process of e-filing is now compulsory and provides a secure and efficient way to file ECI. By understanding the definition of ECI, the importance of filing on time, and the process of e-filing, companies can ensure compliance with tax regulations and avoid any potential issues.
