Article 73 of UAE's Income Tax Decree-Law No. 3 of 1955 establishes the legal basis for tax settlement procedures. It mandates that the specific time limits and procedural rules for settling the tax payable, as declared in a taxpayer's return, are to be detailed in the Executive Regulation of the Decree-Law. This provision delegates the authority for creating the administrative framework for tax payment to subsidiary legislation. It ensures that clear, regulated steps govern how and when a corporate body must settle its tax liability in accordance with the provisions stipulated within the overarching tax decree.
