Guide to Singapore’s Corporate Tax System

Guide to Singapore’s Corporate Tax System

The tax system in Singapore has been competitive and yet an eye-catcher among companies choosing to set up in the lion city. In this article, we will go through the various taxation implemented for companies in Singapore and how they can benefit from the various tax benefits rolled out.

Corporate Tax System in Singapore

The corporate tax framework in Singapore is one of the world’s leading regimes due to its low effective corporate tax rates, and is equipped with many incentives that help reduce these rates.

Firstly, the corporate tax regime in Singapore has a territorial based system where only income generated within Singapore and income remitted or deemed remitted into Singapore is taxed based on the regime. Secondly, the city-state has had a single-tier income tax system since 2003, where the chargeable income taxed is the “final” tax. This means that no further tax is implemented on the dividends distributed from the company to its shareholders. Thirdly, there is no tax on capital gains in Singapore – including gains on sale of fixed assets, gains on sale of capital assets and gains on foreign exchange of capital transactions. Lastly, over the years since 1997, the headline tax rate has been decreasing from 26% to 17%, and the effective tax rates are even lower than that after tax exemptions and other incentives.

Therefore, Singapore has become a popular business hub for both local and foreign investors to set up their businesses here and contribute to the economic growth.

Tax Resident Benefits in Singapore

Generally, a company is considered a tax resident in Singapore if control and management of the business is exercised in Singapore. The location of “control and management” of a business is generally where the Director/Board of Directors’ meetings are held. On the other hand, a company is considered non-resident in Singapore if these meetings are held outside Singapore.

As a tax resident of Singapore, a company would be eligible for (amongst other conditions) the following:

  1. Tax benefits provided under Avoidance of Double Taxation Agreements (DTAs)
  2. Tax exemption on foreign-sourced dividends, foreign branch profits, and foreign-sourced service income under Section 13(8) of the Income Tax Act; and
  3. Tax exemption for new start-up companies.

Payment for Withholding Tax

Under Singapore’s withholding tax laws, for payments made to non-resident companies or individuals and for certain types of income generated in Singapore, a percentage of the payment has to be withheld and paid to the Inland Revenue Authority of Singapore (“IRAS”) by a stipulated date from the date of payment. As a territorial tax system in Singapore, (certain types of) income generated within Singapore will be taxed on non-residences in this manner.

Avoidance of Double Taxation

Singapore has concluded over 90 tax treaties with several countries and the number will continue to grow. This tax treaty is an agreement amongst Singapore and another country on how an income earned in either country will be taxed by both countries, especially if the company is involved in doing business in both countries. The objective of the tax treaty is to help businesses avoid double taxation on the same income.

In addition, Singapore has begun granting unilateral tax credits to local companies for companies who earn income from countries without tax treaties with Singapore. These tax credits are granted to prevent double taxation on the same income.

Industry Specific Tax Incentives

Amongst numerous types of businesses, the IRAS has implemented certain tax rules and incentives for some industries. For more information, please refer to Specific industries.

Goods and Services Tax (“GST”) in Singapore

A GST-registered business may claim GST incurred in their purchases and expenses, if allowed, but must also charge GST on their taxable supplies. The business will serve as an agent of IRAS to collect GST from its supplies while claiming from IRAS GST incurred on their allowable expenses and purchases.
Businesses are required to register for goods and services tax in Singapore when their taxable turnover (revenue) is more than S$1 million at the end of a calendar year, or if they expect their taxable turnover to be more than S$1 million in the next 12 months. Businesses may also voluntarily register for GST as a business decision.
Some businesses may be liable to register for goods and services tax in Singapore under the Reverse charge and Overseas vendor registration regime. Please refer here for more information.

GST Review

Occasionally, IRAS may request for a compliance review on a business’ past GST declarations (GST Form F5), including basis and workings of arriving at the output and input GST. These reviews may also query the activities of the businesses and application of the correct GST regulations.

Using IRAS’ Assisted Self-Help Kit (“ASK”)

In addition to registering for goods and services tax in Singapore, IRAS has several GST Schemes that may be beneficial to businesses.

When applying or renewing certain GST Schemes, IRAS requires businesses to perform an ASK Annual Review prior to the application or renewal of the following GST Schemes.

Applying for GST Schemes

  • Import GST Deferment Scheme  (IGDS);
  • Approved Marine Customer  Scheme (AMCS);
  • Approved Contract  Manufacturer and Trader (ACMT) Scheme;
  • Approved Refiner and  Consolidator Scheme (ARCS);
  • Major Exporter Scheme (MES); 
  • Approved Import GST  Suspension Scheme (AISS); or
  • Approved Third Party  Logistics (3PL) Company Scheme.

Renewing GST Schemes

  • Import GST Deferment Scheme  (IGDS);
  • Major Exporter Scheme (MES);  or
  • Approved Contract  Manufacturer and Trader (ACMT) Scheme.

GST-registered businesses may also adopt ASK on a voluntary basis to do a self-assessment on their past GST submissions and to discover any errors made in those submissions to avoid costly penalties.

The ASK Annual Review is performed based on the latest financial year ended, using either the management accounts or signed financial statements.

The ASK Annual Review must either be performed by:

  1. An individual accredited with Singapore Chartered Tax Professionals Limited (“SCTP”) as Accredited Tax Advisor (GST) [ ATA (GST) ] or Accredited Tax Practitioner (GST) [ ATP (GST) ] OR
  2. The GST-registered business and certified by an individual accredited with SCTP as ATA (GST) or ATP (GST), in adherence to the certification procedures set out in the e-Tax Guide.

The ATA (GST) or ATP (GST) may either be an in-house staff or an external party. Your staff may apply to be an accredited tax professional with the SCTP if he meets the requirements of passing the relevant examinations and having acquired the relevant experience.

Benefits of Adopting ASK

  • Understand GST requirements on filing and record-keeping;
  • Review the accuracy of GST submissions
  • Reduce the risk of incurring penalties on common errors made by  GST-registered businesses;
  • Discover past GST errors early for timely disclosure to IRAS to enjoy  zero or reduced penalties under IRAS’ Voluntary Disclosure Programme (“VDP”);
  • Enjoy administrative concessions for common errors disclosed through  the course of ASK Annual Review; and
  • Fulfil requirements for application or renewal of GST schemes listed in Point 1 of this Guide.

Errors discovered in the course of the ASK Annual Review

IRAS will waive the 5% late payment penalty if businesses undertake the ASK Annual Review to voluntarily disclose past error(s) within one year from the statutory filing date of their last GST return in respect of (i) the financial year or (ii) the 12-month period reviewed. To ease businesses’ review, IRAS recommends that the ASK Annual Review be conducted based on their financial year.

For businesses that do not adopt ASK, the penalty will be waived only if the voluntary disclosure was made within one year from the statutory filing deadline of each GST return. This means businesses adopting ASK Annual Review may enjoy a longer grace period for disclosure of errors. This is provided that all the qualifying conditions under the VDP are met, and the situation does not fall within the specific exclusions from the programme.

For voluntary disclosures made after the one-year grace period, IRAS will impose a reduced penalty of 5% of tax undercharged if the conditions under the VDP are met.

IRAS also grants administrative concession for common errors if these quantifying errors are discovered during the ASK Annual Review. There is no need to seek the Comptroller’s approval to enjoy any of these administrative concessions. No penalties will be imposed on these errors as long as the errors fall within the scenarios described in the list of administrative concessions.
