How we file corporate tax in the UAE
Send your records
Trial balance or management accounts, trade licence and TRN. WhatsApp or email works.
We compute and prepare
Corporate tax computation and return prepared, with a fixed fee agreed before work starts.
Approve, we submit
You review and approve. We handle the corporate tax submission and send you the confirmation.
Optimise your corporate tax liability before the return is filed
Filing is compliance. Optimising is knowing which reliefs and elections apply to you, and claiming them inside the return, where most of them live.
Small Business Relief
Revenue up to AED 3 million? You may elect Small Business Relief and pay no corporate tax this year. The election is made in the return itself.
Free zone 0% rate
Free zone companies meeting the qualifying conditions keep the 0% rate on qualifying income. We test your eligibility before you file, not after.
Tax losses carried forward
Losses declared properly this year offset up to 75% of future profits. Declared wrongly, or not at all, and the benefit is lost.
Adjustments & deductions
Interest caps, entertainment at 50%, non-deductible fines. We make the adjustments that legitimately lower taxable income and skip the ones that invite penalties.
Most of these choices are made inside the return and are hard to reverse. The time to optimise is before submission, not after.
Choose the level of cover that fits
Every plan is a fixed fee, quoted before we start. Not sure which fits? Send the form or WhatsApp us and we will tell you straight.

Corporate tax deadline questions
When is the corporate tax return deadline in the UAE?
Nine months after your financial year end. A 31 December 2025 year end is due 30 September 2026. A 31 March 2026 year end is due 31 December 2026.
What is the late filing penalty for corporate tax in the UAE?
AED 500 for each month, or part month, for the first twelve months from the day after the deadline. It rises to AED 1,000 per month after that.
What is the fine for late corporate tax registration?
AED 10,000. Registration is separate from filing, and you still have to file the return.
We are already past the deadline. Can you still file?
Yes. The penalty accrues monthly, so filing sooner limits what it reaches. Send us the trial balance and we will move.
Can the corporate tax deadline be extended?
There is no general extension. Plan for the nine month date after your year end.
