Double Taxation Avoidance Agreements in Singapore

Singapore has one of the world’s most extensive double taxation agreement (DTA) networks, attracting international businesses from a multitude of conventional and nuanced industries. DTAs eliminate instances of double taxation from cross-border activities, such as trade, knowledge sharing, as well as investments between two countries.

Did You Know
Singapore has signed around 100 DTAs with various countries - including treaties with ASEAN’s 10 member states.

Foreign investors should seek the help of registered tax advisors to better understand how they can benefit from Singapore’s vast DTA network.

Income types covered under a DTA

There are several types of DTAs signed by Singapore: comprehensive, limited, and exchange of information arrangements (EOIAs).

Comprehensive DTAs provide relief from double tax for all income types between the two signatories. Limited DTAs, however, only provides relief from income generated from air transport and shipping, and EOIAs are provisions for the exchange of tax information.

The tax reliefs under each DTA treaty differs for each country. They normally cover several income types:

  • Tax on royalties;
  • Tax on dividends;
  • Tax on capital gains;
  • Tax on interests;
  • Shipping and air transport;
  • Directors’ fees;
  • Independent and dependent personal services;
  • Researchers;
  • Students; and
  • Income from immovable property.

Claiming relief under the DTA

To obtain the benefits of the DTA, the company must first submit its Certificate of Residence (COR) to the IRAS as evidence of a tax residency in Singapore. Only Singaporean tax residents and the tax residents of the treaty partner are recognized.

Tax residents of the treaty partner must also submit a COR certified by the tax authority of the treaty partner to the IRAS in order to obtain relief under the DTA.

Singaporean tax residents can still avoid double taxation even if Singapore does not have a DTA with a particular country through the Universal Tax Credit (UTC) scheme.

This applies to all foreign taxes paid by a Singaporean tax resident on the following income categories:

  • Royalties derived from outside of Singapore;
  • Foreign income from professional services or consultancy;
  • Foreign-sourced dividends; and
  • Foreign branch profits.

The IRAS will grant the tax exemption if the following conditions are met:

  • At least 15 percent in corporate taxes (headline tax) are paid on the income sourced from the foreign jurisdiction;
  • The company has been subjected to tax in the foreign jurisdiction, this can be different from the headline tax; and
  • The IRAS is satisfied that granting the tax exemption will benefit the tax resident in Singapore.

How to claim tax relief under the Double Taxation Agreement (DTA)

Step

Non‑resident company

Non‑Resident Professional (consultant, trainer, coach, etc.)

1. Check eligibility for Double Taxation Relief (DTR)

  • Use the S45 Double Taxation Relief Tax Rate Calculator to determine eligibility and applicable rate under the DTA.
  • Consult the relevant DTA for full relief details.
  • If DTA does not apply, withhold tax at prevailing rate, file, and pay to IRAS by due date.
  • If DTA applies, tick "Double Taxation Relief" box and indicate the rate when filing.
  • Use the DTA Calculator for Non‑resident Professional to check eligibility.
  • View the DTA for full relief details.
  • If DTA does not apply, withhold tax at prevailing rate, file, and pay to IRAS by due date.
  • If DTA applies, check the "Claim for relief under Avoidance of Double Taxation Agreement (DTA)" box and indicate the appropriate rate when filing.

2. Obtain supporting documents

Certificate of Residence (COR) from foreign tax authority for each year claimed.

  • Must be certified by foreign tax authority.
  • In English (or translated copy).
  • Clearly states the entity is tax resident and applicable year(s).
  • One COR may cover multiple years if specified.
  • Certificate of Residence (COR) with same requirements as above.
  • Signed Form IR586 completed by the non-resident professional when tax treaty exemption applies. This is retained by payer and only submitted if requested by IRAS.

3. Submit documents to IRAS by the due date

  • Upload COR (and translation, if any) as a PDF (≤ 3 MB) via IRAS by deadline:
    • 31 Mar of following year for current-year WHT filing.
    • Within 3 months of WHT filing date for preceding years.
  • If not submitted in time, relief may be withdrawn, and penalties may apply.
  • No need to submit original COR unless requested. Retain all records for 5 years.
  • Same upload requirements and deadlines as for companies.
  • Signed Form IR586 need not be submitted unless IRAS requests it.
  • All documents must be retained for 5 years.
  • Option to request online extension (up to 2 months) subject to IRAS approval.

Determining the treatment of profits

Defining a permanent establishment (PE) is an important feature within all DTA treaties in order to determine the treatment of business profits. The PE refers to the fixed place of business through which the taxpayer carries out their business operations.

The taxation of profits falls under the country where the PE is set up unless the company opens a PE in another country. In the absence of a DTA treaty, any profits would mean the PE would bear a double tax burden for the business.

This means foreign investors who have a subsidiary company registered in Singapore can take advantage of the country’s DTAs as well as FTAs through ASEAN and Asia.

A business is deemed to have a PE if they carry out business activities lasting over 183 days in the following places:

  • Offices;
  • Factories;
  • Warehouses;
  • Farm or plantation;
  • Construction or installation site
  • Mines, wells, or quarries; and
  • Workshops.
