How to File Your Yearly Corporate Tax Filing?

STEP 1: File Estimated Chargeable Income (ECI)

The first step to be completed when filing corporate tax in Singapore is that of filing an Estimated Chargeable Income (ECI) form. This form estimates the company’s total amount of chargeable income IRAS within three months of the financial year-end of the company.

Only companies which are specifically exempted from filing an ECI form do not have to do so. These companies which are exempt are those which:

  • Have a total annual revenue of S$5 million or less

  • Did not have any estimated chargeable income during the relevant year of assessment (YA).

Declaration of Revenue in an ECI Form

The ECI must be stated, and company’s revenue must also be declared in the ECI Form. This declaration is compulsory with effect from January 2017.

Revenue refers to a company’s main source of income and excludes items such as gain on disposal of fixed assets. If the company is an investment holding company, the main source of income is investment income (e.g., interest and dividend income).

Should the audited financial statements be unavailable, one can refer to the company’s management accounts for the purpose of declaring the revenue amount. Should the revenue amount based on audited financial statements be different from that declared in the ECI Form, and there is no change in the ECI, the revenue figure does not have to be revised.

STEP 2: File Tax Computation With Form C/CS

Once this has been done, the company owner is to file the company’s annual income tax return with IRAS. This income tax return specifies the exact amount of a company’s income during a specific tax year. It must be filed by every company in Singapore.

Even companies which are to be struck off or liquidated as well as companies which have made losses instead of profits must file this income tax return. Dormant companies are also to file an income tax return, but when they do so, they are to submit a more simplified version instead of the standard tax return form.

The vast majority of companies based in Singapore must use Form C to file an income tax return. Information which is to be submitted on a copy of Form C includes tax computation, financial statements, and supporting schedules. However, there are also certain companies which are to use Form C-S instead of Form C for this purpose.

Such companies must have fulfilled the following criteria:

  • Incorporated in Singapore with annual revenue not exceeding S$5 million

  • Income must have corporate income tax imposed at 17% and therefore no claims on tax reduction

  • No claims on any foreign tax credits or investment allowances for the purposes of tax reduction

What Business Expenses to Be Included in Tax Computations?

Business expenses are expenses paid to keep a business in operation. However, business expenses may be deductible or non-deductible. When deductible, they reduce a taxpayer’s taxable income and the amount of tax which must be paid.

Deductible Business Expenses

Generally, deductible business expenses are those “wholly and exclusively incurred in the production of income”. In other words, they must satisfy all these conditions:

  • Expenses are solely incurred in the production of income.

  • Expenses are not a contingent liability, i.e. they do not depend on an event that may or may not occur in the future. In other words, the legal liability to pay the expenses must have arisen, regardless of the date of actual payment of the money.

  • Expenses are revenue, and not capital, in nature.

  • Expenses are not prohibited from deduction under the Income Tax Act.

If your company satisfies the qualifying conditions, you are eligible for the tax exemption scheme. You can claim a 75% tax exemption on the first S$100,000 and a 50% tax exemption on the next S$100,000 of normal chargeable income for each of the first 3 consecutive years of assessment.

Reduce Your Singapore Corporate Tax Bill

The tax exemptions for qualifying companies (e.g. new start-up companies) for their first 3 consecutive YAs are as follows:

75% TAX EXEMPTION For FIRST $100,00 Normal Chargeable Income
50% TAX EXEMPTION For NEXT $100,00 Normal Chargeable Income

Here are other ways to reduce corporate tax, aside from the new start-up exemption:

Purchase of fixed assets

Buying a fixed assets like machinery or furniture allows a company to accumulate capital allowances. Capital allowances can be claimed in the form of tax deductions.

They pay for a company’s acquisitions of machinery or equipment which are used to generate income for the company. Any capital allowances which have gone unused during a particular YA may be carried forward to subsequent YAs as long as the company has not made any major changes to its primary business activities or shareholdings.

Offset profits

Many companies which have made losses in prior years can lower tax by utilising those losses to offset profits for the current year, lowering the amount of tax money they will be to pay.

For this purpose, companies need to pass the Shareholding Test. The Shareholding Test states that there must not have been any substantial changes in the shareholding of the company between the end of the YA in which the company incurred the losses and the beginning of the YA which is related to the income from which these losses are to be deducted.

What is Form C?2020-07-01T10:23:12+08:00

A company must declare its income by completing the Income Tax Form for companies. This is known as Form C and must be completed each year. 

IRAS will send the first Form C to a newly incorporated company in the second year following the year of incorporation. 

Thereafter, Form C for subsequent YAs will be sent to your company in March or April every year. 

You may need to request for the first Form C to be sent to you earlier, that is, in the year immediately after the year of incorporation (instead of the second year following the year of incorporation) under certain circumstances. 

Note that income is assessed on a preceding year basis. This means that the basis period for any YA generally refers to the financial year ending in the year preceding the YA. 

Example 1 

Your company is incorporated on July 1, 2007, and its financial year end is June 30. 

If your company’s first set of accounts covered the period from the date of incorporation (July 1, 2007) to June 30, 2008, your accounts will be for YA 2009. You do not need to request for Form C for YA 2008. 

Example 2 

Your company is incorporated on July 1, 2007 and its financial year end is December 31. 

If your company’s first set of accounts covered the period from the date of incorporation (July 1, 2007) to December 31, 2007, your accounts will be for YA 2008. In this case, you have to request for Form C for YA 2008. 

  • Form C can be requested via the form titled “Request for Form C for Newly Incorporated Companies or Companies Granted Waiver to Submit Form C/Change of Particulars (36KB)”. 
  • If a company’s first set of accounts covered the period from the date of incorporation to December 31 of a particular year, accounts will be for the YA after the December 31 which ends the period. There is no need to request for Form C for the YA before it. 


Accounts for a given period are to be submitted with the Form C. Form C will be sent to a company in March or April. When filing Form C for a YA, separate tax computations must be submitted for each of two YAs if accounts cover a period of more than 12 months. Income must also be apportioned for each period, and a letter stating that tax computations for the two YAs are enclosed must be attached.
