Below is some essential information for new companies on Singapore corporate income tax and filing obligations.

1. Singapore Corporate Income Tax (CIT)

The company’s income for the preceding financial year is the income for a particular Year of Assessment (YA).

If the company closes its financial year on 31 December 2016, its taxable income for YA 2017 is from 1 January 2016 to 31 December 2016.

If the company closes its financial year on 31 March 2016, its taxable income for YA 2016 is from 1 April 2015 to 31 March 2016.

The prevailing corporate tax rate is 17%. 


2. Key dates to take note

a. The company must submit the Estimated Chargeable Income within three months from the company’s financial year end.

b. The company must submit the income tax form (Form C-S / Form C) by 30 November of every year. If the company opts for e-filing, the due date is on 15 December.


3. All companies must maintain documentary records for five years

The company must maintain a proper and robust system to keep the documentary records of its business transactions during the financial year.

Business records are source documents i.e. sales invoices, receipts, payment vouchers, bank statements, bank-in slips, general ledgers and other forms of documentary records that support the occurrence of related business transactions during the financial year.

The company must keep these business records for at least five years from the relevant Year of Assessment and be retrievable upon request by IRAS.

For example, for YA 2016 (i.e. the financial year from 1 January 2015 to 31 December 2015), the company must keep business records up to 31 December 2020.

4. Submission of annual tax forms to IRAS

ECI Form

Estimated Chargeable Income is the company’s estimated income after deducting tax allowable expenses for the preceding financial year.

For example:

(a) The company is incorporated in the calendar year 2015 and its financial year end is 31 December 2015. The company must submit its ECI for the financial year ended 31 December 2015 to IRAS by 31 March 2016.

(b) The company’s financial year end is not 31 December, the company must submit the Forms “Request for Income Tax Return (Form C-S or Form C)" and "Notification of New Financial Year End” to IRAS once the company closes its first set of accounts.

Form C-S or Form C

There are two forms – Form C-S / Form C.

To qualify to file Form C-S, a Singapore incorporated company must fulfil the following:

1. The company has annual revenue of SGD 1 million or less;

2. The company only derives taxable income at corporate tax rate; and

3. The company does not claim carry-back relief, group relief, investment allowance, research and development tax allowance, foreign tax credit and tax deducted at source.

There is also no requirements to file financial statements, tax computations and supporting schedules unless requested by IRAS.

If your company does not qualify to file Form C-S, the company must file Form C, together with financial statements, tax computations and supporting schedules.

All companies must also declare its actual income or losses in the corporate income tax form annually.

Partial Tax Exemption

All companies can enjoy partial tax exemption unless the companies have already claimed the Tax Exemptions for New Start-Up Companies.

Companies that qualify for this exemption can enjoy 75% tax exemption on the first SGD 10,000 of chargeable income and a further 50% tax exemption on the next SGD 290,000 of chargeable income.
