United Arab Emirates reporting cycles and business-day rules
UAE business-day cycles align with FTA (Federal Tax Authority) VAT201 quarterly deadlines (28 days after quarter-end for non-grouped registrants) and monthly returns for designated taxpayers. The UAE Central Bank operates UAEFTS as the wholesale RTGS system on bank business days. The federal public sector switched from a Friday-Saturday weekend to Saturday-Sunday in January 2022 and the private sector largely aligned. Corporate income tax was introduced June 2023 at 9%; tax returns are due nine months after the financial year-end. Free Zone Persons under the Qualifying Free Zone regime enjoy 0% on Qualifying Income. ADGM and DIFC operate independent commercial-law regimes.
