Tax & Compliance

The UAE compliance calendar: every dated filing for 2026 on one page.

A UAE entity is never “compliant” the way it is “licensed” — once, with a document to show for it. It is compliant the way a plane is airworthy: continuously, against dates that carry penalties when they pass unnoticed. These are those dates.

Three deadlines worth diarising first.

01

UBO changes — fifteen days

Any change in beneficial ownership must be filed within fifteen days, all entities, no materiality threshold. Penalties start at AED 50,000, and this is the deadline nobody diarises because it has no fixed date.

02

Small Business Relief now runs to 2029

Ministerial Decision 131 of 2026 extended the relief to tax periods ending on or before 31 December 2029. The AED 3 million revenue threshold is unchanged, it must have been met in every prior period, and the relief is elected in the return rather than granted automatically.

03

e-Invoicing is phased, and phase one is close

Businesses with revenue of AED 50 million or more must appoint an accredited service provider by 30 October 2026 and be live on structured e-invoicing from 1 January 2027. Smaller businesses follow in 2027. The pilot that opened in July 2026 was voluntary.

The calendar

Every date, and what each one actually requires.

Maintained as regulations move. Dates that depend on your financial year end are marked — if yours does not end in December, several of these shift with it.
