A Certificate of Residence (COR) is a letter certifying that you are a tax resident in Singapore for the purpose of claiming benefits under the Avoidance of Double Tax Agreements (DTAs).

Reasons to apply for a COR
If you derive income from a foreign country/jurisdiction, you may be subject to tax there. However, you may claim tax benefits if there is a DTA between Singapore and the foreign country/jurisdiction. To enjoy the tax benefits, you need to submit a COR to the foreign tax authority to prove that you are a Singapore tax resident.
A DTA is an agreement signed between Singapore and the country/jurisdiction that serves to relieve double taxation of income earned in one country/jurisdiction by a resident of the other country/jurisdiction. It provides clarity on when and how tax is to be imposed in the country/jurisdiction where the income-producing activity is conducted or payment is made. Under the DTAs, countries/jurisdictions may provide tax breaks (e.g. tax credit or exemption) to tax residents of Singapore on the income derived from their jurisdictions. Non-tax residents do not enjoy these benefits.
