UAE tax calendar: recurring deadlines and 2026 to 2027 dates

These repeat every period:

• VAT returns: usually due within 28 days of the end of the tax period, according to the UAE government portal. Periods are quarterly for turnover below AED 150 million and monthly at or above it, unless the FTA assigns another period.
• Corporate tax return and payment: within nine months of the end of the tax period.
• Corporate tax registration for a new UAE company: within three months of incorporation.
• Resident individuals crossing AED 1 million of business turnover: register by 31 March of the following year.
• Transfer pricing master and local files, where required: within 30 days of an FTA request.

From FTA and Ministry of Finance announcements:

• 30 September 2026: corporate tax returns and payment for tax periods ended 31 December 2025.
• 1 October 2026: Ministerial Decision No. 197 of 2026 changes to e-invoicing take effect.
• 28 October 2026: final VAT return deadline listed in the FTA's announcements.
• 30 October 2026: businesses with revenue of AED 50 million or more appoint an e-invoicing ASP.
• 16 November 2026: final excise return deadline listed by the FTA.

The milestones to plan around next:

• 1 January 2027: e-invoicing go-live for revenue of AED 50 million or more; the 24-month tax group exclusion begins.
• 31 March 2027: ASP appointment for businesses below AED 50 million and for government entities.
• 31 March 2027: corporate tax returns due for tax periods ended 30 June 2026.
• 1 July 2027: e-invoicing go-live for businesses below AED 50 million.
• 1 October 2027: e-invoicing go-live for government entities.
• 31 December 2029: last tax period end date covered by small business relief under current rules.

Deadlines differ by entity when year ends and VAT periods differ. In HelloBooks each company holds its own year end and VAT period, and the AI agent sends reminders ahead of each due date with the current status of the books: unreconciled accounts, unposted bills, missing documents. Ask "what is due in the next 60 days across our companies?" for one list. Filing and payment remain with you or your tax agent on EmaraTax. Partner firms can request a firm-wide deadline view customised to their client list at /book-a-demo.
