Corporate Tax Return Deadline
Corporate Tax Return Deadline in the UAE: The 9-Month Rule Explained
Every taxable person files one corporate tax return per tax period, due — together with payment — within nine months of the period's end. Nine months sounds generous until audit sign-off, adjustments and elections have to happen inside it.
- Your exact deadline computed from your financial year
- Filing calendar working back from audit sign-off
- Return and payment submitted with margin
- Elections and reliefs claimed inside the return

Quick Answer
The corporate tax return and payment are due within 9 months of the end of the tax period. December year-end companies file by 30 September of the following year; March year-ends by 31 December; June year-ends by 31 March. Late filing costs AED 500 per month for the first 12 months (AED 1,000 monthly after), and late payment adds an annual-rate charge on the unpaid tax.
Working Out Your Date
The deadline is mechanical: financial year end plus nine months. The subtleties are in the first period — incorporation dates can create a long or short opening period — and in the fact that payment shares the same deadline as the return. There are no quarterly instalments or provisional returns; the full liability lands at once.
- 31 December year-end → file and pay by 30 September
- 31 March year-end → file and pay by 31 December
- First periods may be longer or shorter than 12 months
- Payment is due with the return — plan the cash, not just the form
Why Nine Months Gets Tight
The return consumes everything upstream of it: closed books, audited or at least finalised financial statements, tax adjustments, transfer pricing schedules and relief elections. Businesses that start at month seven discover their auditors, their records and the FTA portal all have their own timelines. The comfortable version of this process starts within three months of year end.
- Audit sign-off often takes months on its own
- QFZP claimants need audited statements — no shortcuts
- Transfer pricing disclosures need data gathering
- Elections (SBR, groups, reliefs) are made in the return, not after
Missing It: The Cost Structure
Late filing penalties accrue monthly — AED 500 per month or part-month for the first twelve, AED 1,000 monthly thereafter — and unpaid tax accrues its own annual-rate late payment charge. A return filed eight months late with tax owing is a five-figure mistake before the underlying tax is even touched.
- AED 500/month late filing, first 12 months
- AED 1,000/month thereafter until filed
- Late payment charge accrues on unpaid tax from the due date
- Chronic lateness invites audit attention on the substance too
The First Return Is the Hard One
The first corporate tax return carries work that later years will not. The opening tax period may be longer or shorter than twelve months depending on incorporation timing, transitional adjustments for assets held before the regime began have to be settled, and one-time elections — the realisation basis, transitional relief, small business relief — are locked in here and mostly cannot be added later. Treating the first deadline like a routine one is how businesses miss elections worth far more than the return itself.
- Opening periods can be longer or shorter than 12 months
- Transitional adjustments for pre-regime assets are settled here
- First-return-only elections cannot be added afterwards
- The first computation sets the pattern for every later year
Building a Filing Calendar That Holds
Nine months is comfortable only if you work backwards from the deadline rather than forwards from good intentions. Closing the books within roughly three months of year-end, completing any audit next, then building the computation and confirming elections leaves margin for the FTA portal and the cash to fund the payment. Businesses that start the process at month seven routinely find their auditors, their records and the portal all have their own timelines.
- Close the books within about three months of year-end
- Complete audit or finalisation before building the computation
- Confirm elections early — they are made in the return
- Leave margin for portal submission and funding the payment
Planning the Single Payment
Because there are no instalments, the whole year's tax falls due on one date alongside the return. A profitable company should set the money aside through the year — treating the 9% liability as a provision accrued month by month — rather than scrambling to find it at month nine. Aligning the payment cash with the filing calendar is as important as preparing the return; a filed return you cannot pay simply switches one penalty meter for another.
- The full year's tax is due in one payment with the return
- There are no quarterly instalments to spread the cost
- Provision for the 9% liability monthly through the year
- Fund the payment date, not just the filing date
When is the UAE corporate tax return due?
Within 9 months of your tax period's end — 30 September for December year-ends, 31 December for March year-ends. Payment is due by the same date.
Are there quarterly corporate tax payments in the UAE?
No — one annual return and one payment per tax period. That makes cash planning for the single payment date essential.
What is the late filing penalty?
AED 500 for each month (or part) of delay in the first 12 months, rising to AED 1,000 monthly afterwards — plus late payment charges on any unpaid tax.
Does my first period follow the calendar year?
Your first tax period follows your financial year as declared at registration; incorporation timing can make it longer or shorter than 12 months.
Can the deadline be extended?
There is no standard extension mechanism — the working assumption must be that the nine-month date is final.
Can I file my corporate tax return early?
Yes, once the tax period has ended and the accounts are finalised you can file ahead of the nine-month deadline. Filing early removes deadline risk, though the payment is due on the same date whenever you file within the window.
What tax period does a company set up mid-year have?
Its first tax period runs from incorporation to its first financial year-end, which can make that opening period longer or shorter than twelve months. The nine-month deadline then runs from the end of that period.
Is the payment deadline the same as the filing deadline?
Yes. Both the return and the payment are due within nine months of the tax period's end — there is no separate, later payment date, so the cash has to be planned alongside the filing.
How can I plan cash for the corporate tax payment?
Treat the expected 9% liability as a monthly provision, setting the cash aside as profit accrues, so the single payment at the nine-month deadline is already funded rather than a year-end surprise.
