On 3 December 2025, the UAE published consolidated versions of:

  • Federal Decree-Law No. 28 of 2022 on Tax Procedures, as amended by Federal Decree-Law No. 17 of 2025 applicable to every tax imposed under the United Arab Emirates tax law, that the Federal Tax Authority is mandated to administer, collect and enforce;
