Income Tax Compliance

With our vast experience handling tax issues for clients from various industries, we are able to assist you on your tax filing matters. These include submission of your Estimated Chargeable Income (ECI) and income tax returns (Form C/C-S) for companies.


ECI is the estimate of a company’s chargeable income for a particular Year of Assessment. It is mandatory for a company to file its ECI with the Inland Revenue Authority of Singapore (IRAS) within three months from its financial year-end, unless the company qualifies for ECI waiver for that Year of Assessment.

The conditions for ECI waiver are summarized in the table below.

Company's Financial Year end Conditions for ECI waiver
In or before Jun 2017 1. annual revenue is not more than $1 million for the financial year; and
2. ECI is NIL for the YA
In or after Jul 2017 2. annual revenue is not more than $5 million for the financial year; and
3. ECI is NIL for the YA

We are able to assist and advise you with your ECI filing obligations.

Form C-S / Form C submission

The annual filing due date for Form C-S/Form C is 30 November (for paper filing) and 15 December (for electronic filing).

An income tax computation needs to be prepared to ascertain the numbers to be filled up in the Form C-S/C. There are various aspects to consider with preparing an income tax computation including:

  • Taxability of income/gains
  • Deductibility of expenses
  • Capital allowance claims
  • Foreign tax credit claims
  • Applicability of tax incentives

Given our experience in advising on the tax matters for companies in various industries, we can advise you on the above and assist you to prepare your company’s income tax computation and Form C/C-S.
