You can claim deduction for expenses that are wholly and exclusively incurred from the production of income.

To qualify for tax-deduction, the expenses must:

  • Be revenue-focused in nature. This covers normal day-to-day expenses, but excludes capital expenditure.
  • Not be prohibited under the Income Tax Act.
  • Have actually been incurred. Contingent liability is not allowed for tax deduction.

Yes, it is mandatory. All Singapore Incorporated Companies are required to file a tax return on an annual basis. Although the company is making losses, the losess still have to be submitted via tax return to IRAS. The losses can be utilised to set off against future profits of the company.

“ECI” stands for Estimated Chargeable Income. It is an estimate of a company’s chargeable income for a Year of Assessment (YA).

A company has to furnish Estimated Chargeable Income (ECI) within three months after the financial year end of the company.

If you furnish your company’s ECI within the qualifying period, you can pay your tax by instalments basis. The earlier you furnish your ECI, the higher the number of instalments available.

The due date for filing corporate tax return in Singapore is November 3o annually. The tax return is filed on prior year basis i.e. any financial year end fall in 2016 will need to file tax return for the financial year on 30 November 2017. The filing deadline is extended to 15 December, if the company is e-filing the tax return.

Howver, each company is required to file an Estimated Chargeable Income (ECI) within 3 months of the end of its financial year to IRAS.

No. Singapore adopts one-tier corporate tax system; 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.

We will advise and update you on the Corporate Income Tax matters so that your company’s tax obligation is in compliance to the Income Tax Acts. It includes: 

  • Preparation and submission of Estimated Chargeable Income (“ECI”) within 3 months from financial year end.
  • Corporate income tax computation of the tax payable of company.
  • E-filing of Tax Return in Form C or Form C-S to IRAS.
  • Assisting your company to verify the Notice of Assessment upon receipt of the assessment from IRAS and deal with corporate income tax queries raised by IRAS if any.

A dormant company MUST submit Form C-S  unless it has been granted waiver for submission of tax return by IRAS.

GST stands for Goods and Services Tax. The company is liable to register for GST when its annual taxable turnover is moree than S$1 million or it is currently making taxable supplies and its annual taxable turnover is expected to be more than S$1 million for the next 12 months. A company may choose to register for GST voluntarily if the annual sales turnover is less than S$1 million, however, the company needs to remain as GST registered company for at least 2 years.

Upon registering GST, a business must charge and account for GST at the prevailing rate (7%). This is known as output tax. GST registered businesses can also claim from IRAS the GST incurred on their goods and services purchased assuming certain conditions are met. This is known as input tax.
