Inland Revenue Authority of Singapore

If you’ve ever paid taxes in Singapore, you would have received communication from the Inland Revenue Authority of Singapore (IRAS). IRAS is the tax collector for the Government of Singapore, and all tax-related regulations of the island-nation are handled by them.

What is IRAS and what does it do?

IRAS was created in 1947 as the Singapore Income Tax Department. It began evaluating and collecting tax in November 1948. The Inland Revenue Department was created in 1960 when Singapore became a self-governing nation.

The Inland Revenue Authority of Singapore was set up by legislation in 1992 as a statutory board under the Ministry of Finance. The incorporation of the organisation was performed through the Inland Revenue Authority of Singapore Act and effectively replaced the earlier Inland Revenue Department.

IRAS functions not only as a tax collector and administrator, but also as a tax advisor to the government of Singapore. IRAS also represents Singapore in all tax matters of globally. IRAS assesses and collects all kind of taxes in Singapore, including income tax, property tax, and goods and services tax (GST). It helps provide most of the operational costs of the government. The government’s operating revenue is mainly derived from taxes (85.8%), fees and charges, and other earnings.

Taxes covered by IRAS

The IRAS is responsible for handling the following Acts and the taxes associated with them:

  1. Income Tax Act – Income tax
  2. Economic Expansion Incentives (Relief from Income Tax) Act
  3. Estate Duty Act – Estate duty
  4. Stamp Duties Act – Stamp duty
  5. Goods & Services Tax Act – GST
  6. Property Tax Act – Property tax
  7. Casino Control Act – Casino tax
  8. Betting and Sweepstakes Duties Act – Betting tax
  9. Private Lotteries Act – Betting tax

Other taxes such as Foreign Worker Levy, Airport Passenger Service Charge, Motor Vehicle Tax, Customs Duty and Excise Duty are not under the purview of IRAS. They are managed by the relevant departments of the government.

Tax system in Singapore

The main purposes of tax collection in Singapore are:

  1. To bring in revenue for the government
  2. To further the socio-economic goals of the country

IRAS aims to have a reasonable taxation regime for both individuals and companies. This way, Singaporeans and permanent residents are not bogged down by tax liabilities, and local entrepreneurship, productivity and employment creation thrives. The competitive tax system is also designed to encourage foreign companies and individuals to invest in Singaporean ventures.

The tax rates and rules are differentiated according to the tax type and entities under each type. The categorisation is done as given below:

For Income Tax:

  • Singapore citizens and permanent residents
  • Foreigners (tax residents and non-tax residents)
  • Companies (including self-employed persons, sole proprietors and partners)

For GST:

  • GST-Registered businesses
  • Non GST-Registered businesses
  • Consumers

For Property Tax:

  • Property owners

Other Miscellaneous Taxes

Each entity has to pay taxes as per the regulations laid out for them alone, and do not need to concern themselves with any rules related to the other party. This helps avoid confusion and offers a great amount of clarity to tax payment in Singapore.

Income Tax in Singapore

Income Tax is the tax you pay on your annual earnings to the government of the country you reside in or make your money in. The earnings include your salary or business income, rental income, and housing and stock options offered by your employer. You don’t have to pay any income tax on Singapore dividends, interest earned on bank deposits and income earned outside Singapore.

Income Tax in Singapore is decided on the basis of your residency status. The tax rates are progressive for residents and fixed for non-residents. The rates for residents range from 0% for the first S$20,000 that you earn, to 22% on any amount above S$320,000. The rates for non-residents is the higher of 15% or the resident rates applicable as per your income. While residents can enjoy tax relief and exemptions, non-residents get no such perks.

Corporate tax for companies is levied at a rate of flat 17% on chargeable income. This is applicable whether the company is local or foreign. Clubs and Associations are subject to the same tax structure as a company.

The income tax assessment year for Singapore is January 1 to December 31. IRAS will send you the Notice of Assessment by September every year. You need to file your tax returns before 15 April of the following year. For tax purposes, the basis period of the Year of Assessment (YA) – or the tax year – would be the previous year, or the relevant year of income. For example, if you are a salaried individual, your YA 2018 would consider the income received between 1 January 2017 to 31 December 2017. But if you are a businessperson who follows a fiscal year of April 1 to March 31, then your YA 2018 would be 1 April 2016 to 31 March 2017.

Tax can be paid in the following ways:

  • Internet Banking
  • Credit cards
  • GIRO transfers
  • AXS Stations
  • AXS e-station/m-station
  • SAM Kiosks
  • SAM Web or SAM mobile

Several tax rebates, tax reliefs and tax exemptions are available to all kinds of tax-paying entities except to non-residents.

Property Tax in Singapore

Property tax is the tax you pay for owning a property in Singapore. Property tax rates are calculated by multiplying the annual value of your property with the applicable property tax rates. The annual value of the property is determined by market conditions, especially the assessed monthly rent of your property based on the general value of property in your area.

For example, if the rent of your property is estimated at S$650 per month, then the annual value of that property would be S$7,800. Based on this annual value, if the tax rate is 15%, then your property tax amount would be S$1,170.

The property tax slabs depend on the following parameters:

  • Owner-occupied residential property: The tax rate on a property which is occupied by the owner themselves ranges from 0% for the initial annual value of S$8,000 to 16% for values above S$130,000.
  • Non-owner occupied residential property: If the owner of a property does not live in it, and is either rented out or lying vacant, the tax slabs are different. It starts from 10% for the initial annual value of S$30,000 and goes up to 20% for values above S$90,000. Several residential properties that function as serviced apartments, welfare homes, students’ hostels or hospitals are part of exclusions that have to pay a flat property tax rate of 10%.
  • Commercial and industrial property (non-residential): All commercial and other non-residential properties have to pay a property tax of 10%. This is a fixed rate and has no variations irrespective of whether it is owner-occupied or not.

Goods & Services Tax(GST) in Singapore

Goods and Services Tax (GST) is levied on all sales and purchases of goods and services in Singapore, irrespective of whether the item is made in Singapore or imported. The standard rate of GST is 7% currently. There are zero-rated products and services such as export of goods and international services; exempted goods and services such as sale or renting of a residential building that is unfurnished and life insurance services; as well as out-of-scope goods and services such as private transactions and sales made in Free Trade Zone.

You need to register for GST if your taxable income for the 1-year ending in any quarter is over S$1 million. Even if your business is not making such a turnover, you can voluntarily register for GST. The amount you charge as GST should be paid to IRAS as output tax. Input tax is the GST your business pays on purchases for production or regular operations. If you are eligible to claim input tax, you can do so and either get a refund from IRAS or pay only an amount that is the difference between your input and output taxes.

Withholding Tax in Singapore

Withholding tax is collected when a payer is making some kinds of payments to non-resident companies or individuals. These payments include: management fees, technical service fees, royalty, interest, commission, etc. The withholding tax rates for each category are different, and are listed in the table below:

Other taxes in Singapore

IRAS also collects Stamp Duty, Estate Duty, and taxes from Charities and Trusts.

Stamp duty is collected on shares, property, and property-holding entities. Documents such as lease and tenancy agreements, property transfer papers, and mortgage are subject to stamp duty. The rate ranges from 1% to 3% as Buyer’s Stamp Duty, 15% as Additional Buyer’s Stamp Duty and 12% as Seller’s Stamp Duty.

Estate Duty is collected when someone has died and leaves monetary or asset inheritance for kith and kin. However, since 15 February 2008, Estate Duty has been discontinued. The inheritance bestowed on beneficiaries after the death of a person is taxed at the rate of 17% (as the legal personal representative) if the income is not distributed before 31 March in the year after the YA. If the income is distributed before this time, then the applicable tax rate is as per the beneficiary’s personal income.
