A COR (sometimes called “Certificate of Residence”) is an official document confirming the country where an individual or company is a tax resident for Double Taxation Agreement (DTA) purposes.
You must provide a COR each year to enjoy reduced WHT rates under Singapore’s tax treaties.
Other proofs (e.g., residence cards, tax paid slips) aren’t accepted for treaty benefits.

A valid COR is mandatory if you receive Singapore-sourced interest and want to use a treaty-reduced WHT rate. Without it, the default WHT of up to 15% applies.
Non-resident investors (individuals or entities) seeking treaty relief on Singapore-sourced income (e.g., interest from certain deals) should submit a COR annually.
Per IRAS, a COR must:
- Be certified by the foreign tax authority of the non-resident.
- Be in English (or accompanied by a certified English translation).
- Clearly state that the person/entity is a foreign country/region resident for DTA purposes and the year(s) the COR applies to.
You typically apply via your home country’s tax authority after 31 December for the prior calendar year.

WHT may apply to interest if the issuer is Singapore-based or the debenture is issued from a Singapore-based SPV.
If neither is Singapore-based, WHT doesn’t apply.
- Option 1 (Reduced WHT): Opt for a treaty-reduced rate by committing to provide your COR. Submit the COR after year-end but before the end of February (e.g., for 2025 income: 1 Jan 2026 – 28 Feb 2026).
- Option 2 (Flat WHT): Don’t provide a COR and accept a 15% WHT.
