UAE Compliance Calendar October 2026 to December 2027: Every Tax and Licence Deadline

The short answer. Between October 2026 and December 2027 there are only four compliance dates in the UAE that are the same for everybody: 30 October 2026 to appoint an Accredited Service Provider, 1 January 2027 for e-invoicing to go live on large businesses, 1 July 2027 for everyone below AED 50 million, and 1 October 2027 for government entities. Every other date on this page — corporate tax, value added tax, audited accounts, licence renewals — is worked out from something each client owns: their financial year end, the tax period the Federal Tax Authority assigned them, or the day their licence was issued. That is why a forty-client practice does not keep one calendar. It keeps forty.

Why a UAE compliance calendar is not one calendar

Search for a UAE compliance calendar and you will find a grid of months with dates printed in them. It looks reassuring and it is mostly wrong, because the two obligations that carry the largest penalties do not have national dates at all.

Corporate tax is due nine months after the end of the tax period. Not nine months after December. Nine months after that client's year end. A client with a 31 March year end files by 31 December; a client with a 30 June year end files by 31 March of the following year. Both are correct, and a calendar that prints one date for corporate tax is telling half your book the wrong thing.

Value added tax works the same way. The return is due on the twenty-eighth day after the tax period ends, but which twenty-eighth depends on the stagger the Federal Tax Authority assigned that registrant when it approved them. Three clients registered in the same week can sit in three different quarters.

So this page is in two halves. First the dates that really are fixed, which you can put on a wall. Then the rules that generate the rest, which you have to run per client — and the table that turns a year end into a filing date without arithmetic.

The dates that are fixed for everybody

These four apply on the same day regardless of whose books you are looking at.

One date that is often still listed as upcoming has already passed: the amended administrative penalty regime came into force on 14 April 2026. It is not a deadline any more. It is the regime you are already being penalised under, and the section below explains what changed.

E-invoicing: the two dates in this window that actually bite

The UAE's electronic invoicing system is set out in Ministerial Decision No. 243 of 2025 on the scope of the system and Ministerial Decision No. 244 of 2025 on its implementation, both issued on 29 September 2025 under Federal Decree-Law No. 8 of 2017 on value added tax. The Ministry of Finance then amended that timetable, announcing the change on 10 May 2026.

The amendment is the part most calendars have not caught up with. The deadline to appoint an Accredited Service Provider was originally 31 July 2026. It moved to 30 October 2026 under the Ministry of Finance's amendment of 10 May 2026. The go-live date did not move — it is still 1 January 2027.

That combination is the whole problem. A business that uses the full extension has roughly nine weeks between choosing a provider and having to issue compliant invoices through them. The appointment is not the work; it is the thing that lets the work start.

The phases run like this:

The practical job for a firm this quarter is not technical. It is to sort the client book by revenue, find everyone at or above AED 50 million, and confirm each of them has actually signed with a provider rather than intending to. The threshold is revenue, so a client can cross it without anything about their business feeling different.

Corporate tax: the deadline your client's own year end sets

The rule is one sentence. The return and the payment are both due nine months after the end of the tax period, and there is no separate, later payment window. A firm that files on time and pays a fortnight later has still paid late. Registration is a separate obligation carrying its own flat penalty.

This table turns a financial year end into its filing date across the whole window. Read down to your client's year end and across.

Four of those dates land on a UAE weekend. Some published calendars move them to the following working day; the nine-month rule itself is written in months, not business days, so do not assume the shift — confirm the working deadline for that client in EmaraTax before you plan around it.

The December year ends are the ones that bunch. If most of your clients close on 31 December, then 30 September is not a deadline for one client — it is the day a large part of your book is due at once, and the work has to be spread across the nine months before it rather than the three weeks after Eid.

Value added tax: the twenty-eighth, and which twenty-eighth

The return and the payment are due by the twenty-eighth day following the end of the tax period. The standard tax period is three months. The Federal Tax Authority assigns monthly periods to some registrants, which in practice tends to follow turnover.

What a calendar cannot tell you is which quarter a given client sits in, because the authority sets that per registrant. There are three common quarterly staggers:

If you are not certain which group a client is in, the answer is in their EmaraTax account and nowhere else. Assuming the calendar quarter because it is the obvious one is how a firm discovers a stagger it did not know about, one day late.

Excise tax: monthly, on the fifteenth

If a client imports, produces or stockpiles excise goods, the excise return and payment are due by the fifteenth day following the end of the tax period, which is normally a calendar month. Where the fifteenth falls on a weekend or a public holiday it moves to the next working day.

This affects a small slice of a typical practice — tobacco products, electronic smoking devices and the liquids used in them, carbonated drinks, energy drinks and sweetened drinks — but it runs twelve times a year rather than four, so a client who is in scope generates more deadlines than the rest of the book put together.

Audited financial statements: who actually needs one

Ministerial Decision No. 84 of 2025, issued on 14 April 2025, sets out who must prepare and maintain audited financial statements for corporate tax purposes. It applies to tax periods starting on or after 1 January 2025 and repeals Ministerial Decision No. 82 of 2023, which continues to apply to periods that began before that date.

Two points change what a firm has to plan for:

• A taxable person that is not a tax group needs audited financial statements where revenue is AED 50 million or more. The test is revenue, not accounting profit and not taxable income.

• The AED 50 million threshold was removed for tax groups. Every tax group now has to prepare and maintain audited special purpose financial statements, whatever its consolidated revenue.

For a non-resident person, only revenue derived through permanent establishments or a nexus in the state counts towards the threshold.

The scheduling consequence is that an audit is not a single event at the year end. It has to be booked far enough ahead of the corporate tax deadline that the return is not waiting on it, which for a 31 December year end means the audit is a first-half job, not a September one. What the auditor asks for is the same file an FTA audit would ask for.

Small Business Relief: what changed in August 2026

On 7 August 2026 the Ministry of Finance announced Ministerial Decision No. 131, extending Small Business Relief to tax periods ending on or before 31 December 2029. The revenue threshold is unchanged at AED 3 million.

This matters for a calendar because a great deal of published UAE guidance still says the relief runs out at the end of 2026. It does not. A client with revenue under AED 3 million who elects the relief is treated as having no taxable income for that period, and that remains available for three more years than most sources say.

The election is still an election. It has to be made, and it is not available to a Qualifying Free Zone Person or to a member of a large multinational group.

Four things most UAE compliance calendars still get wrong

These are the corrections worth checking any calendar against, including one you have been keeping yourself.

The economic substance one is worth dwelling on. Cabinet Decision No. 98 of 2024 did not pause the regime, it ended it for financial years ending after 31 December 2022, abolished the related penalties for those years, and provided for pending penalties to be annulled and paid penalties on rejected appeals to be returned. The years from 1 January 2019 to 31 December 2022 are still live: those filings, corrections and penalties remain enforceable and the authority can still assess them. So there is nothing to put in a 2027 calendar, and something to check in an old file.

The penalty regime you are already under

Cabinet Decision No. 129 of 2025 came into force on 14 April 2026. It brings value added tax, excise tax and corporate tax under one penalty framework.

Among the changes the Federal Tax Authority has set out:

• Failure to submit tax documents in Arabic falls from AED 20,000 to AED 5,000.

• Failure to notify the authority of an amendment to tax records falls from AED 5,000, and AED 10,000 on repetition, to AED 1,000 per violation and AED 5,000 for a repeat within twenty-four months.

• Failure to notify the appointment of a legal representative falls from AED 10,000 to AED 1,000.

• The compounding structure on overdue tax was replaced by a flat annual rate.

The direction of travel is that administrative slips got cheaper and unpaid tax did not. For a practice, that is an argument for fixing the record-keeping violations that used to be expensive and never letting a payment date slide.

Trade licences and establishment cards: the quiet ones

These have no national date at all. A trade licence expires on the anniversary of its issue, which depends on the authority that issued it and the day the entity was set up. An establishment card runs on its own clock alongside it.

They get missed for a reason that has nothing to do with difficulty: they come round once a year, they are somebody's job rather than the firm's routine, and nothing in the accounting cycle reminds anyone they exist. The consequence of missing one is disproportionate — fines, a licence that lapses, and in the worst case a visa and bank relationship that depend on it.

The only reliable approach is to hold the expiry date for every entity in the same place as the tax dates, and to start the renewal far enough out that a document request to the client is not itself the emergency. The same client file usually carries the KYC and anti-money-laundering documents, which run on a renewal rhythm of their own.

Emiratisation: the 2026 dates, and the 2027 gap

Private sector establishments with fifty or more employees are required to increase Emiratis in skilled roles by one per cent every six months, two per cent across the year, with the half-year deadlines falling on 30 June and 31 December. Contributions for missing a target are collected semi-annually.

The contribution started at AED 6,000 per month for each unfilled position in January 2023 and rises by AED 1,000 a year until 2026 — which puts it at AED 9,000 per month, or AED 108,000 a year, for 2026. Separately, Cabinet Decision No. 43 of 2025 sets fines for circumventing the quota at AED 100,000 for a first offence, AED 300,000 for a second and AED 500,000 for repeated breaches.

Here is the honest part, and it is the reason to be careful with any 2027 calendar you are handed: as at 30 September 2026, the Ministry of Human Resources and Emiratisation has not published targets or contribution rates beyond 2026. The published escalation runs "until 2026" and the ten per cent overall target is set "by 2026". The pattern of 30 June and 31 December deadlines is well established, so those dates are worth holding. The numbers attached to them for 2027 are not announced, and a calendar that states them is guessing.

How a firm runs this across a whole client book

Everything above is a rule. The difficulty in a practice is not knowing the rules — it is that the rules produce a different date for every client, and the dates arrive one at a time, months apart, while the work in front of you is whatever is due this week. Freeing those hours is what makes year-round advisory work possible at all.

Three things tend to separate firms that stay ahead of this from firms that do not.

The dates live with the client record, not in a spreadsheet. A year end, a value added tax stagger, a licence expiry and an establishment card expiry are facts about a client. When they are held as facts about a client, a new client arrives with its deadlines already known rather than waiting for someone to add a row.

The reminder comes early enough to be useful. A corporate tax return that surfaces in its ninth month is not a reminder, it is a fire. The useful alert is the one that arrives with months left, and then again as the date closes.

A deadline becomes somebody's task. An alert that nobody owns is an email. The gap between "this is due" and "this is done" is where the penalty lives.

This is the problem AudiTax.ai's compliance tracker is built around. Compliance dates are created with the client from the client's own fields — the corporate tax period end, the value added tax due date, the licence and establishment card expiries — and the system raises five kinds of alert as those dates approach. Corporate tax alerts are counted forward monthly from the period end, from the third month through to the ninth; value added tax alerts fire at eighteen, twelve and six days before the due date and again on the day; licence and establishment card alerts at thirty, twenty and ten days and on the day. An alert becomes a task with an assignee and an activity log, so the path from due to done stays in one place. Firms that want the whole picture rather than the deadline layer alone can start from practice management software for accounting firms.

What to do this quarter

1. Sort the client book by revenue and confirm every client at or above AED 50 million has signed with an Accredited Service Provider. The date is 30 October 2026.

2. List the corporate tax deadlines for the next twelve months from each client's year end, using the table above, and look at where they bunch.

3. Check each value added tax registrant's assigned stagger in EmaraTax rather than assuming the calendar quarter.

4. Identify which clients cross the AED 50 million revenue line for audited financial statements, and every tax group, which now needs them regardless.

5. Re-check any client you told the Small Business Relief was ending this year.

6. Collect trade licence and establishment card expiry dates into the same place as the tax dates.
