The Department of Revenue & Customs, under the Ministry of Finance of Bhutan, has released an addendum to a previously published public notification dated 26 June 2026. This addendum modifies and expands upon the original announcement, clarifying the scope of the measures related to revenue collection and customs procedures. It specifies that the updated guidelines apply to all registered taxpayers, importers, and exporters operating within the country, and it provides detailed instructions on the submission of revised tax returns, the calculation of applicable duties, and the timing of payment. The document also introduces new compliance checkpoints, outlines the documentation required for audit purposes, and defines the penalties for non‑compliance. Additionally, the addendum sets new deadlines for filing certain returns, which are effective from 1 July 2026, and it details the procedural steps for electronic submissions through the Ministry’s online portal. The Ministry emphasizes the importance of strict adherence to these revised timelines to avoid interest charges or enforcement actions. To support stakeholders, the Department has published frequently asked questions and a guidance note on its website, and a dedicated helpline has been established for queries. The addendum further references relevant sections of Bhutan’s Income Tax Act and Customs Act, reinforcing the legal basis for the measures. Overall, the update aims to enhance transparency, streamline revenue collection, and reduce the administrative burden on taxpayers while ensuring that the government’s fiscal objectives are met. Stakeholders are encouraged to review the full text of the addendum carefully and to implement the changes without delay.
