Certificate of Residence: How Singapore Companies Claim Tax Treaty Benefits

What a Certificate of Residence is

A Certificate of Residence (COR) is a letter from IRAS confirming that a company is tax resident in Singapore for a given year. Foreign tax authorities and payers ask for it before they apply the reduced rates in a Double Tax Agreement (DTA).

Why it matters

When a Singapore company earns dividends, interest, royalties or service fees from another country, that country may deduct withholding tax at source. Singapore’s wide DTA network can reduce or remove that withholding tax, but only if the company can prove it is a Singapore tax resident. The COR is that proof.

How tax residence is decided

A company is tax resident in Singapore when its control and management is exercised in Singapore. In practice, this usually means the board makes its strategic decisions in Singapore, with board meetings held here.

Being incorporated in Singapore is not enough on its own. IRAS may ask for more evidence from investment holding companies and companies owned by foreign parents, such as proof of local substance and where decisions are made.

How to apply

1. Confirm the company meets the residence test for the relevant year.
2. Apply through IRAS’s myTax Portal and provide supporting details when asked.
3. If the foreign authority has its own form, have it certified by IRAS as well.
4. Give the COR to the foreign payer or tax authority before payment, where possible.

Practical tips

• Keep board minutes showing meetings and decisions held in Singapore.
• Apply for each year you need. A COR covers a specific period.
• Check the specific DTA article. The reduced rate depends on the type of income and sometimes on shareholding levels.
