Key Takeaways
4 insights · 13 min readCorporate tax filing is due 9 months after the tax period ends — a 31 December 2025 year-end must be filed and paid by 30 September 2026.
Late filing costs AED 500/month for 12 months, then AED 1,000/month. Unpaid tax runs at 14% a year, charged monthly, with no cap.
A return is a computation, not data entry: non-deductible expenditure, exempt income, interest limitation, losses and elections all have to be worked before anything is submitted.
Mismatches between the corporate tax return and the VAT returns for the same period are the most common FTA audit trigger. Cross-check before filing, not after.
Every UAE business registered for corporate tax must file a return on EmaraTax within 9 months of its tax period end — including nil, loss-making and 0% free zone entities. Late filing costs AED 500 per month for the first 12 months, then AED 1,000. Fastlane files from AED 249 per return.

The fee difference between them is often small. The consequence difference is not — one produces a defensible return, the other produces a submission you may have to explain later. This guide covers what the 2026 deadlines actually are, the correct penalty schedule, what belongs in a computation, and how to tell the two apart. If you already know what you need, our corporate tax filing service starts at AED 249 per return.
Who must file a corporate tax return in the UAE?
Every taxable person registered for corporate tax files an annual return — without exception for size, profitability or rate. Under Federal Decree-Law No. 47 of 2022, filing is triggered by registration, not by having tax to pay.
That catches four groups who routinely assume otherwise: companies with nil activity, companies that made a loss, companies below the AED 375,000 nil-rate threshold, and free zone entities expecting 0%. All four file. In the last case the point is structural rather than administrative — the return is the mechanism through which Qualifying Free Zone Person status and qualifying income are reported, so a free zone company that does not file has no route to the 0% rate at all.
Resident natural persons are the one genuine carve-out. There is no personal income tax in the UAE, and an individual only enters the corporate tax net on UAE business turnover above AED 1 million in a Gregorian calendar year. Below that, there is nothing to register for and nothing to file.
What is the corporate tax filing deadline in 2026?
Nine months after the end of the tax period. The same date covers both filing the return and paying any corporate tax due — there is no separate, later payment deadline, which is where cash-flow planning usually goes wrong.
| Tax period end | Filing and payment deadline | Position at 27 August 2026 |
|---|---|---|
| 31 December 2024 | 30 September 2025 | Passed — penalties accruing |
| 31 March 2025 | 31 December 2025 | Passed — penalties accruing |
| 30 June 2025 | 31 March 2026 | Passed — penalties accruing |
| 31 December 2025 | 30 September 2026 | Due in about 5 weeks — the largest cohort |
| 31 March 2026 | 31 December 2026 | Upcoming |
| 30 June 2026 | 31 March 2027 | Upcoming |
The 30 September 2026 row matters most: December year-ends are the default for the majority of UAE entities, so this is the single busiest filing date in the calendar. EmaraTax slows noticeably in the final fortnight before a major deadline, and a portal timeout on the last day is still a late filing.
⚠️ Already past a deadline? Filing late still reduces the damage
The monthly penalty keeps accruing until the return is filed, so a return that is nine months late costs less than the same return filed twelve months late. There is no benefit whatsoever in waiting. Get an overdue return filed →
What are the penalties for late corporate tax filing?
Late filing costs AED 500 for each month or part month for the first twelve months, rising to AED 1,000 per month from month thirteen. Unpaid corporate tax attracts 14% per annum, charged monthly, with no cap.
| Breach | Penalty | How it accrues |
|---|---|---|
| Late corporate tax return | AED 500 then AED 1,000/month | AED 500 per month for months 1–12, AED 1,000 per month from month 13 |
| Late payment of corporate tax | 14% per annum | Charged monthly on the unpaid balance — no cap |
| Late registration | AED 10,000 | One-off; waivable if the first return is filed within 7 months of the first tax period end |
| Late deregistration | AED 1,000/month | Monthly from the missed 3-month deadline, capped at AED 10,000 |
| Failure to keep records | AED 10,000 / AED 20,000 | AED 10,000 first offence; AED 20,000 for a repeat within 24 months |
| Incorrect return not voluntarily disclosed | Percentage-based | Varies with whether disclosure is made before FTA action [VERIFY against the current CD 75/2023 schedule] |
⚠️ Corporate tax penalties are not set by the VAT penalties decision
Corporate tax administrative penalties sit under Cabinet Decision No. 75 of 2023, as amended by Cabinet Decision No. 10 of 2024. Cabinet Decision No. 129 of 2025, effective 14 April 2026, governs VAT and excise penalties — it does not set corporate tax filing penalties, and nothing in the table above derives from it. A provider quoting CD 129/2025 for a corporate tax deadline is working from the wrong instrument.
Worked example: what eight months of delay costs
A Dubai mainland LLC with a 31 December 2024 year-end had a filing deadline of 30 September 2025. The return is finally filed in May 2026, eight months late, showing corporate tax payable of AED 84,000.
The arithmetic
• Late filing — 8 months × AED 500 = AED 4,000
• Late payment — AED 84,000 × 14% per annum for 8 months ≈ AED 7,840
• Total added cost — roughly AED 11,840, against a filing fee of AED 499
• If left another five months — the monthly filing penalty steps up to AED 1,000 from month 13, and the 14% keeps compounding on the unpaid tax

What does a proper corporate tax computation include?
A corporate tax return is not your profit and loss account transcribed into a portal. Taxable income starts from accounting profit under IFRS and is then adjusted — and those adjustments are where the tax outcome is actually decided.
What has to be worked before submission
• Non-deductible expenditure — entertainment is restricted, fines and penalties are not deductible, and expenditure not wholly and exclusively for the business is disallowed. Owner drawings misposted as expenses are the classic SME finding.
• Exempt income — qualifying dividends and the participation exemption remove income from the base entirely, but only where the conditions are met and evidenced.
• Interest limitation — net interest expenditure is deductible up to the higher of 30% of adjusted EBITDA or AED 12 million under the general interest deduction limitation rule. Relevant to leveraged and group-financed entities.
• Loss carry-forward — brought-forward losses can offset up to 75% of taxable income in a period, subject to continuity of ownership and business conditions. Requires the prior-year return.
• Related-party adjustments — arm's length pricing applies to related-party dealings with no threshold at all. The AED 40 million and AED 200 million figures in Ministerial Decision No. 97 of 2023 govern disclosure and documentation, not whether the rule applies.
• Elections — Small Business Relief, realisation basis and QFZP treatment are all made in the return and generally cannot be added afterwards.
Expert Tip
Ask a prospective provider one question: "Will you send me the computation before you submit?" A firm doing the work will send you a schedule reconciling accounting profit to taxable income. A firm doing data entry will send you a confirmation after the fact. The answer tells you which service you are buying.
Can you still claim Small Business Relief?
Small Business Relief lets a taxable person with revenue at or below AED 3 million elect to be treated as having no taxable income for the period. You still register and still file — the liability is simply nil.
The mechanics matter more than most summaries suggest. The relief is elected in the return itself, for each eligible period, and cannot be backdated. It is available where revenue does not exceed AED 3 million in the relevant tax period and in all previous tax periods. QFZPs cannot elect it, and neither can members of a multinational enterprise group with consolidated revenue above AED 3.15 billion.
⚠️ Two corrections to what is widely published about SBR
Missing one year's election does not disqualify you permanently. Failing to elect in one tax period forfeits the relief for that period only; you can elect again in a later eligible period. What does permanently end eligibility is exceeding the AED 3 million revenue threshold — once breached, the relief is gone for all subsequent periods.
On the sunset date: Ministerial Decision No. 73 of 2023 as originally issued limited the relief to tax periods ending on or before 31 December 2026. Our current working position is that this has been extended to tax periods ending on or before 31 December 2029 — [VERIFY the amending instrument and effective date against the Ministry of Finance source before relying on any future-year availability]. Either way, the election is made period by period, so nothing is lost by electing now.
Because eligibility turns on revenue rather than profit, a business can be loss-making and still fail the test. Our Small Business Relief page sets out the eligibility conditions in full, and every Fastlane filing includes an SBR assessment as standard.
How does corporate tax filing work for free zone companies?
Free zone entities file exactly like everyone else, but with more riding on the return. The 0% rate is not a status you hold — it is a position you evidence, tax period by tax period, through the return.
To be a Qualifying Free Zone Person, an entity must maintain adequate substance in the free zone, derive qualifying income from qualifying activities under the current instrument (Ministerial Decision No. 229 of 2025, which superseded the earlier decisions), prepare audited IFRS financial statements, and stay within the de minimis threshold — non-qualifying revenue below the lower of AED 5 million or 5% of total revenue.
✅ QFZP conditions met
- 0% on qualifying income for the tax period
- 9% on non-qualifying income within the de minimis
- Audited IFRS financial statements in place
- Substance in the free zone evidenced
- Position reported and supported in the return
❌ De minimis breached
- QFZP status lost for the period
- 9% from the first dirham on all income
- No AED 375,000 nil-rate band on non-qualifying income
- Status lost for that period and the following four
- Small Business Relief is not available as a fallback
The audited financial statements requirement is the one that catches people at filing time, because an audit cannot be produced in the week before a deadline. Fastlane is a Ministry of Economy-approved auditor for IFZA, DMCC, JAFZA, DSO, DWC, MEYDAN and RAKEZ, so the free zone audit and the corporate tax return can run as one engagement rather than two.
What documents do you need for corporate tax filing?
Requirements scale with revenue. The lighter end is genuinely light — but "not submitted with the return" is not the same as "not required to exist".
| Revenue band | What we need | Note |
|---|---|---|
| Under AED 3M, electing SBR | Revenue figure and EmaraTax access | Financial statements are not submitted, but records evidencing the revenue must be kept |
| AED 3M – 50M | Income statement, balance sheet, prior-year return, VAT returns | Prior-year return needed for loss carry-forward; VAT returns for cross-checking |
| Above AED 50M | Audited financial statements | Audit is mandatory at this revenue level [VERIFY the current governing Ministerial Decision] |
| Any QFZP | Audited financial statements | A condition of QFZP status regardless of revenue |
| Related-party dealings | Transfer pricing documentation and related-party detail | Where the MD 97/2023 disclosure and documentation thresholds are met |
Regardless of band, records must be retained for seven years following the end of the relevant tax period. That obligation survives both a nil return and the closure of the business.
How much do corporate tax filing services in Dubai cost?
Fastlane prices per return, by revenue band, with the computation included rather than billed separately. There are no retainers and no hourly add-ons.
| Plan | Fee per return | Included |
|---|---|---|
| Basic — revenue under AED 3M | AED 249 | Return filing, Small Business Relief assessment, EmaraTax submission, FTA acknowledgement |
| Business — revenue AED 3–10M | AED 499 | Full computation, non-deductible expense review, loss carry-forward, VAT cross-verification |
| Enterprise — revenue above AED 10M or QFZP | AED 999 | Comprehensive computation, QFZP assessment, transfer pricing review, interest limitation analysis, exempt income review |
| Related services | AED 199 / AED 399 / from AED 149 | CT registration / CT deregistration / VAT filing |
For context, indicative UAE market rates for a standard return run considerably higher, and large advisory firms price registration and filing as part of wider engagements. Those are observed ranges rather than quoted prices — always get a fixed fee in writing, and confirm whether it includes the computation or only the submission.
How do you choose reliable corporate tax filing services in Dubai?
Four checks, all of which can be made before you engage anyone.
What to verify
• FTA Tax Agent registration — only a registered Tax Agent can file on your behalf. Ask for the firm's tax agent registration and confirm it on the FTA's public register before sharing EmaraTax credentials.
• Computation included, in writing — the fee should cover reconciling accounting profit to taxable income, not just the submission. Ask to see the computation before filing.
• VAT cross-verification as standard — if the firm also sees your VAT returns, inconsistencies get caught before the FTA finds them. If it does not, ask how the check is done.
• Entity-type experience — QFZP filings, natural persons, foreign branches and holding companies each carry different elections and evidence requirements. A provider should recognise your structure without being told.
Turnaround is worth calibrating too. A straightforward SBR filing is a few hours' work; a larger computation is reasonably three to five working days. Anyone quoting two to three weeks is describing a queue, not a process. For a broader view of the market, see our guide to choosing a corporate tax provider.
What does the filing process actually look like?
- Share the financials — income statement and balance sheet, or just the revenue figure where Small Business Relief is being elected. A tailored checklist follows if anything is missing for your entity type.
- Tax computation — accounting profit is adjusted for non-deductible expenditure, exempt income, interest limitation and brought-forward losses, and relief eligibility is assessed. You receive the computation for review before anything is submitted.
- VAT cross-verification — revenue in the corporate tax return is reconciled to revenue declared in the filed VAT returns for the same period. Legitimate differences are documented rather than left to be queried.
- EmaraTax submission — the computation is entered, the required elections made, and the return submitted inside the nine-month window.
- Acknowledgement and payment — the FTA acknowledgement is issued, any liability is settled by the same nine-month date, and the file is retained with the supporting records for seven years.
What triggers an FTA corporate tax audit?
There is no published list, but the patterns are consistent enough to plan around. Most are avoidable at preparation stage, which is the strongest practical argument for paying for a computation rather than a submission.
The patterns that draw attention
• CT and VAT revenue that do not reconcile — the single most common trigger. Differences are often legitimate (out-of-scope supplies, timing, exempt income), but unexplained ones invite questions.
• Related-party transactions with no transfer pricing support — management fees, group loans and cross-charges to shareholders, unsupported by any arm's length analysis.
• A 0% QFZP claim without audited financial statements — claiming a status whose stated condition has not been met.
• Nil returns from entities with visible activity — a nil or dormant return alongside bank movement, active VAT filings or payroll.
• Large unexplained book-to-tax adjustments — a wide gap between accounting profit and taxable income with no supporting schedule.
What sits alongside corporate tax filing services in Dubai?
Filing is one obligation in an annual cycle, and the pieces feed each other. Bookkeeping produces the numbers, the audit supports them where required, and the VAT returns have to agree with them.
| Obligation | When | Fastlane fee |
|---|---|---|
| Corporate tax return | 9 months after tax period end | From AED 249 |
| VAT return | 28 days after each tax period end | From AED 149 |
| Bookkeeping | Ongoing — the basis of the return | From AED 499/month |
| Free zone audit | Annual, where required or claiming QFZP | From AED 1,499 |
| CT registration | One-off, per FTA Decision No. 3 of 2024 | AED 199 |
| CT deregistration | Within 3 months of cessation | AED 399 |
If you are closing rather than continuing, the sequence reverses and the deadlines tighten — see our guide to corporate tax deregistration, where the final return has to be pulled forward and filed before the deregistration application. And if you want to model a liability before engaging anyone, the UAE corporate tax calculator gives a first estimate.
