Witholding Tax - Claim of relief


Section 77 of the Income Tax Act governs the “Repayment of tax and deduction where tax paid or payable affected by double taxation relief”. Accordingly, any non-resident from a country that have signed Avoidance of Double Taxation Agreement (ADTA) with Brunei Darussalam who wishes to claim relief under such ADTA, may initiate its request by filing the Income Tax Return for the relevant Year of Assessment.*

The basis of claim may be incorporated in an application addressed to the Collector of Income Tax (Revenue Division) for requisite relief by identifying the relevant provision of the ADTA which is relied upon in support of the claim. The following supporting documents may be attached:

  1. Official letter addressed to the Collector of Income Tax, Revenue Division, stating the reason for the request;
  2. The Certificate of Residence (COR) for the relevant Year of Assessment from the tax authority of non-resident’s country of residence after the Year of Assessment period has been completed;
  3. Invoices of the transaction;
  4. Proof of payment in case of excess witholding tax paid;
  5. Contract or any written agreement in respect of the relevant transaction; and
  6. Any other necessary evidence in support of entitlement to relief under the ADTA.  

As Brunei Darussalam adopts preceding year basis of taxation for all sources of income, non-residents may apply for the relief after the end of the basis period relevant to the Year of Assessment. The basis period January 2015 till Dec 2015 falls in the Year of Assessment 2016. The return of income for YOA 2016 should be filed between 1st January 2016 and 30 June 2016.

* Income Tax Return Form for non-residents has to be requested by email ( by providing the non-residents details such as name of company, company’s registration number in their country of residence and registered address for Revenue Division to generate the form manually.
