Cabinet Decision No. 39 of 2019, Article 26, specifies the content and issuance of the tax card. A single card is issued per registered person, containing the taxpayer's name, address, tax number, and commercial license details. It also lists the number of branches and the start date of activity. Significantly, the Authority will not issue a tax card for income tax purposes to non-resident taxpayers who operate via a permanent establishment, distinguishing their status from resident entities. This card serves as the primary identifier for all tax-related interactions in Qatar.
