Corporate Tax

A company is taxed on the income earned in the preceding financial year.

The Year of Assessment (YA) is the year in which the income is assessed to tax.  The income and expenses during the financial year is used to assess the amount of tax. In tax terms, this financial year is known as the “basis period“.

The basis period is a 12-month period preceding the YA.

31 Jan of each year 1 Feb 2014 – 31 Jan 2015 2016

Annual Filing to IRAS

All companies need to submit two corporate income tax forms to IRAS every year:

Estimated Chargeable Income (ECI) form within three months from the company’s financial year end except for (a) companies that fulfil the conditions under the Administrative Concession; and (b) certain entities that are not required to file ECI; and

Corporate Income Tax Returns commonly known as Form C-S or Form C by 30 Nov of each year except dormant companies for which IRAS has waived the requirement to file.  Companies must ensure that the form gives a full and true account of the company’s income.

Proper records of its financial transactions and retain the source documents, accounting records and schedules, bank statements and any other records of transactions connected with your business must be maintained and a company must retain the records for a period of five years from the relevant YA.

Tax Rates

Singapore adopts a one-tier corporate tax system under which tax paid by a company on its chargeable income is the final tax. All dividends paid by a company are exempt from tax in the hands of the shareholders.

A company is taxed at a flat rate of 17% (2010) on its chargeable income regardless of whether it is a local or foreign company.

Capital gain such as gains on sale of fixed assets or gains on foreign exchange on capital transactions is not taxable.

Some Income such as foreign-sourced dividends, branch profits & service income received by a resident company that satisfies the qualifying conditions may be exempted from tax under the provisions of the Singapore Income Tax Act.
