Can I amend my ECI filing after submission?

Yes, it may be possible to amend your Estimated Chargeable Income (ECI) filing after submission if you discover that the information provided was incorrect or incomplete.

ECI is an estimate of a company's taxable income for a Year of Assessment and must generally be filed within three months after the end of the company's financial year. Because it is based on estimated figures, situations may arise where adjustments become necessary after submission.

Common reasons for requesting an amendment include:

• Errors in the original ECI calculation
• Omitted income or expenses
• Updated financial information becoming available after filing
• Significant changes to the company's estimated taxable profits

If you identify an error in your submitted ECI, you should contact the Inland Revenue Authority of Singapore (IRAS) as soon as possible to explain the situation and determine whether an amendment can be made. Supporting documents may be required to substantiate the revised figures.

Companies should not wait until the final tax assessment is issued before addressing known errors. Prompt disclosure helps ensure that the company's tax position is accurately reflected and may reduce the risk of compliance issues.

It is also important to remember that the ECI is only an estimate. The company's final tax liability will ultimately be determined based on its Corporate Income Tax Return and supporting financial information submitted to IRAS.

In summary, an ECI filing may be amended after submission if corrections are required, but companies should notify IRAS promptly and provide supporting information to support any requested changes.
