Singapore has one of the most competitive corporate tax regimes in the world. The tax rate has been steadily revised downwards to sustain economic growth and prosperity. The tax framework has been a key pull factor in attracting international investments and enterprises to Singapore. The Inland Revenue Authority of Singapore (IRAS) is responsible for administering, assessing and collecting tax. The following is an overview of the Singapore corporate Tax system.
Singapore follows a territorial tax policy meaning corporate tax is levied only on that portion of the income that is generated in Singapore or received in Singapore.
Singapore adopts a Single –tier tax system under which tax paid by a company on its chargeable income is the final tax. Dividends received by the shareholders are not subjected to tax.
Other key features of the Singapore corporate tax regime are
New startup companies enjoy full tax exemption on the first $100,000 of chargeable income for its first three consecutive Years of Assessment (YA).
Effective from YA 2008, the startups are entitled to a further 50% exemption on the next $200,000 on the chargeable income.
The effective tax rate for new start-up companies on their chargeable income for the first three years is as follows:
| Chargeable Income | Effective Tax rate |
| S$100,000 | 0% |
| S$100,001 –S$300,000 | 8.5% |
| S$300,001 onwards | 17% |
In order to qualify for the tax exemptions under new start-ups scheme the company must
A partial tax exemption is given to all companies on normal chargeable income of up to $300,000 as follows
| Chargeable income | Effective Tax Rate |
| First S$10,000 | 4.25% |
| Next S$10,001 – S$300,000 | 8.5% |
| Above S$300,001 | 17% |
Note: For YA 2011, companies will be granted a 20% rebate or a 5% SME cash grant, whichever is the higher amount.
Small companies operating in Singapore immensely benefit from the competitive tax rate, as more often their revenue is relatively low and their tax liabilities are substantially slashed by such partial exemption.
Foreign sourced incomes of Singapore tax resident companies are exempted from tax if they satisfy certain conditions. Foreign sourced incomes such as dividends, foreign branch profits and service income that is remitted into Singapore on or after 1st Jun 2003 are exempted from local corporate tax if the following conditions are met:
For the purpose of taxation, incomes of following nature accrued in Singapore or received in Singapore are subjected to tax
Accounting profit or loss does not depict the true quantum of taxable income. Accounting profit is subjected to tax adjustments such as non-deductible expenses, non-taxable receipts, further deductions and capital allowances. Thus the chargeable income of a company will be different from the accounting income or loss. Some of the expenses incurred by the company may not be deductible for tax purposes. Likewise, some of the income received by the company may not be taxable or it may be taxed separately as a non-trade source income.
Generally, a company can claim tax deduction for expenses that are incurred for business, if the following conditions are met
Note: Under the Productivity and Innovation Credit Scheme currently companies are allowed to deduct up to 400% of certain expenses such as qualifying R&D and staff training expenses.
Capital allowance, trade loss or donation in excess of a company’s income from all sources for a current year may be carried forward to future years and/or transferred to another company within the same group for set-off against the income of the other company, subject to conditions.
For the purpose of taxation, a company is deemed resident in Singapore if the control and management of its business is exercised in Singapore.
A Singapore branch of a foreign company is deemed as non-resident since the control and management is vested with an overseas parent company.
Though the basis of taxation of a resident and non resident company is the same, the resident companies enjoy certain privileged treatment in the form of exemptions, incentives and benefits.
A Singapore resident company gets to enjoy the following privileges
In Singapore income is assessed on a preceding year basis. This means that the basis period for any Year of Assessment (YA) is the financial year ending in the year preceding the YA. For instance, if your financial year end is 31 Mar of each year, the basis period for YA 2011 is 1 Apr 2009 to 31 Mar 2010. Also note that the basis period for each year of assessment cannot exceed 12 months. New startups must take note of this and if the start-up’s first set of accounts cover a period of more than 12 months then the incomes must be apportioned to two YAs.
The Product and Innovation Credit (PIC) Scheme has been further enhanced for Singapore Budget 2011. It is a scheme to provide tax incentives so as to encourage business to invest and upgrade along the innovation value chain. The chart below outlines the benefits of PIC:
