Singapore Tax Filing Calendar

When must I file my Singapore taxes?

Whether you are an individual or a corporate entity, knowing when to file your taxes will be essential, particularly if you want to avoid paying penalties or the horror of dealing with a court summons.

Rikvin, a professional firm specialising in tax and accounting services, provides a comprehensive guide on when and how individuals and corporate entities should compute and file their taxes.

Personal Tax – What Do I Need to Know?

Singapore’s Personal Tax system is a progressive tax system where the tax percentage charge depends on an individual’s taxable income. To put it simply, individuals with higher annual chargeable incomes will pay a higher percentage of tax.

If you fulfill any of the criteria below, you would be considered as a tax resident by the Inland Revenue Authority of Singapore (“IRAS”):-

• A Singapore citizen who normally resides in Singapore except for temporary absences;
• Permanent Resident who has established a permanent home in Singapore; or
• Foreigner who has stayed or worked in Singapore for 183 days or more in the prior year

However, there are exceptions. For example, if one is a Singapore Citizen or Permanent Resident who has worked and lived overseas for a period of time, your overseas income will not need to be declared and will not be taxable, even if this income is credited to a Singapore bank account.

To understand more about how you may qualify for this exemption, do seek the advice of a professional tax agent, who would be able to advise you accordingly.

How Do I Compute my Personal Tax?

How much tax one has to pay is contingent on your total chargeable income, which is your annual chargeable income before CPF deductions. Thereafter, if you qualify for tax reliefs, deduct the tax reliefs from the annual chargeable income, before computing your tax based on the corresponding tax rate that you have to pay.

Corporate Tax – What Do I Need to Know?

Singapore has adopted a one-tier corporate tax system and tax paid by a company on its chargeable income is the final tax. A company’s corporate tax is calculated based on the net income earned by companies while exercising their business activities in the period of one business year.

There are three main tax obligations that companies will have to pay attention to, as follows:-

1. Filing of Estimated Chargeable Income (“ECI”)
2. Corporate Income Tax – Form C-S/Form C-S (Lite) or Form C
3. Filing of Goods and Services Tax (“GST”) payment

For the ECI and GST, the deadline for companies is dependent on its financial year end or accounting period, very much like the deadline for when a company’s Annual General Meeting (“AGM”) is due.

For Form C-S/Form C-S (Lite)/Form C, this is more similar to a Personal Income Tax and all companies will have to comply with the same due date as this is computed based on the Year of Assessment (“YA”), rather than the company’s own financial year end.

Filing of ECI

A company’s ECI is computed based on an estimate of the company’s taxable income (after deducting tax-allowable expenses) for a YA. All companies are required to file their ECI, even if their estimated ECI is zero.

Companies that are exempted from filing their ECI would need to fulfill both conditions:

• Annual revenue of S$5 million and below for the FA
• ECI is NIL for the YA

In addition, certain entities such as real estate investment trusts (“REITs”), foreign universities, designated unit trusts etc. are not required to file ECI.

All companies are required to file their ECI within three months from their financial year end. Read Rikvin’s guide on ECI to find out more!

Filing Corporate Income Tax – Form C-S/Form C-S (Lite)/Form C

Depending on your company type, your company will need to submit either a Form C-S/C-S (Lite)/C to IRAS. The table below provides a quick overview of the differences between the 3 forms.

Filing of GST Payment

GST is basically Singapore’s version of VAT in the European countries. Unlike the ECI, only companies that are GST-registered businesses will need to file their GST payments. Understand what it means to be a GST-registered business when you read Rikvin’s comprehensive guide.

While ECI filing is due only once a year, after a company’s financial year end, GST filing is due every quarter, as shown in the table below:

To help companies avoid penalties and the consequences of missing their GST filing deadlines, IRAS has allowed companies to opt for a GIRO plan, where GST payments will be automatically deducted. However, companies should ensure that their accounts have sufficient payment before the payment deduction date.

Payment is deducted on the 15th of the month after the payment due date. If deduction is unsuccessful, the GIRO arrangement will be cancelled, and you must make full tax payment at the myTax Portal or re-activate the GIRO arrangement.

It is possible to apply for an extension of time, however, this request must be submitted to ACRA before the filing due date; and is subject to IRAS’ discretion. IRAS will typically review the reason and supporting documentation. The maximum extension allowed for is only two weeks.
