Key Takeaways
4 insights · 16 min readEvery registered business must file a corporate tax return — even with zero tax, losses, Small Business Relief or QFZP status. A nil return is still mandatory.
The deadline is 9 months after your financial year-end. For year-end 31 Dec 2025 that is 30 September 2026; filing and payment share the same date.
Corporate tax is 0% up to AED 375,000 and 9% above it. Revenue up to AED 3M can elect Small Business Relief and pay 0%.
Late filing costs AED 500/month (then AED 1,000). Fastlane files a complete return in 3 hours from AED 249.
A UAE corporate tax return is filed electronically to the FTA through EmaraTax, once per tax period, within 9 months of your financial year-end. You must file even if you owe nothing. Tax is 0% on the first AED 375,000 of taxable income and 9% above it; businesses with revenue up to AED 3 million can elect Small Business Relief and pay 0%. Missing the deadline triggers an AED 500/month penalty regardless of whether tax was due.

Corporate tax took effect on 1 June 2023 under Federal Decree-Law No. 47 of 2022, and the first returns fell due from late 2024. If your company is registered with the Federal Tax Authority (FTA) — and virtually all mainland and free-zone companies must be — you have to file, on time, even in a year with no profit. This guide walks through every step so you can file correctly, claim the reliefs you are entitled to, and avoid penalties. If you would rather hand it over, our UAE corporate tax team files a complete return in about three hours.
You must file even if you owe zero tax
Companies claiming Small Business Relief, holding Qualifying Free Zone Person status, or reporting a loss still must file a corporate tax return — a nil return is required. The AED 500/month late-filing penalty applies whether or not any tax is payable. “No tax due” is never a reason not to file. Not registered yet? Start here →
What is a corporate tax return, and must you file with zero tax?
A corporate tax return is a mandatory filing submitted electronically to the FTA through the EmaraTax portal. It reports your company’s income, expenses, deductions, relief elections and taxable income for a specific tax period — normally your financial year. Only one return per tax period is required: there are no quarterly, provisional or advance filings. You file once, pay once, and you are done for the year.
And to be unambiguous: yes, you file even if the tax is zero. Whether you owe nothing because your income is below AED 375,000, because you elected Small Business Relief, because you are a QFZP on qualifying income, or because you made a loss — the return itself is still compulsory.
Who must file a corporate tax return in the UAE?
Every taxable person registered for corporate tax with the FTA must file. That includes:
- Mainland companies — LLCs, sole establishments, civil companies and branches of foreign companies.
- Free zone companies — FZEs, FZCs and branches, including Qualifying Free Zone Persons.
- Joint stock companies — public (PJSC) and private (PrJSC).
- Natural persons conducting business — individuals whose UAE business turnover exceeds AED 1 million a year.
- Partnerships treated as taxable persons — certain unincorporated partnerships.
Exempt persons — government entities, certain public-benefit organisations and qualifying investment funds — are generally not required to file, although the FTA may still request registration in specific cases. Unsure where a corporate tax consultant would place your structure? It is worth confirming before your first deadline.
What are the corporate tax rates for 2026?
The headline rates are simple; the nuance is in the reliefs and the free-zone regime.
| Taxable income / status | Rate | Notes |
|---|---|---|
| Up to AED 375,000 | 0% | Applies to all taxable persons |
| Above AED 375,000 | 9% | Standard rate on the excess only |
| Revenue ≤ AED 3M (with election) | 0% | Small Business Relief — must be elected |
| QFZP qualifying income | 0% | Free-zone entity meeting substance & conditions |
| QFZP non-qualifying income | 9% | Standard rate on the non-qualifying portion |
Large multinationals: the 15% top-up
Groups within scope of the OECD Pillar Two rules — broadly, multinational enterprises with consolidated global revenue of at least €750 million — are subject to the UAE’s Domestic Minimum Top-up Tax (DMTT) of 15% for financial years starting on or after 1 January 2025. Most SMEs are unaffected, but if you belong to a large group, factor this in. Want a quick estimate first? Try the UAE corporate tax calculator.
What are the corporate tax return filing deadlines by financial year?
The return must be filed — and any tax paid — within 9 months of the end of your financial year. Payment falls on the same date as filing. These are the key reference dates:
| Financial year-end | First tax period length | Filing & payment deadline |
|---|---|---|
| 1 Jun – 31 Dec 2023 | 7 months | 30 September 2024 |
| 1 Jan – 31 Dec 2024 | 12 months | 30 September 2025 |
| 1 Jul 2023 – 30 Jun 2024 | 12 months | 31 March 2025 |
| 1 Jan – 31 Dec 2025 | 12 months | 30 September 2026 |
| 1 Apr 2025 – 31 Mar 2026 | 12 months | 31 December 2026 |
Don’t confuse registration with filing
Corporate tax registration (obtaining your TRN) is a separate obligation from filing the return. Even if you registered late, your filing deadline is still fixed by your financial year-end — late registration does not push it back. Newly incorporated companies whose first tax period ended on or before 29 February 2024 were given a one-off extended deadline of 31 December 2024 to file and pay; if that was you and it was missed, address it now.
Which documents do you need for your return — by revenue tier?
What you must prepare scales with your revenue. Here is the breakdown.
| Revenue tier | What you need |
|---|---|
| Below AED 3M | Revenue figure for the period, trade licence, TRN, EmaraTax login |
| AED 3M – 50M | Income statement (P&L), balance sheet, trade licence, TRN, EmaraTax login, related-party transaction details and transfer-pricing disclosure (if applicable) |
| Above AED 50M | All of the above plus audited financial statements (mandatory) and related-party disclosures |
Two thresholds people mix up
Audited financial statements become mandatory once revenue exceeds AED 50 million (and for all QFZPs, regardless of revenue). A full transfer-pricing master file and local file is only required where your standalone revenue reaches AED 200 million in the period, or you are part of a multinational group with consolidated revenue of at least AED 3.15 billion. Below AED 200 million you may still need to complete the transfer-pricing disclosure form for related-party dealings, but not the master/local file. If you need statements prepared, our accounting and bookkeeping and audit teams handle both.
Don’t have your financials ready?
We prepare your P&L, balance sheet and audited statements, then file the return — all in one place.
How do you file a corporate tax return on EmaraTax, step by step?
All returns are filed electronically through the FTA’s EmaraTax portal. The process runs in six steps.
- Log in to EmaraTax — go to eservices.tax.gov.ae, sign in, and open your corporate tax account.
- Select the tax period — choose the correct period and confirm the start and end dates match your financial year.
- Complete the return form — enter revenue, cost of goods sold, operating expenses, other income, deductions and adjustments, and elect any reliefs (Small Business Relief, QFZP election, exempt income).
- Report exempt & non-deductible items — separately disclose exempt income (qualifying dividends, qualifying capital gains), non-deductible costs (fines, penalties, excess entertainment) and related-party transactions.
- Compute the tax liability — the system calculates taxable income and tax; verify it and apply any foreign tax credits.
- Review, submit & pay — check the return, submit electronically, and pay any tax due through the same portal before the deadline.
Expert Tip
The most expensive errors happen at steps 3 and 4 — misclassifying income or missing a relief election. If your numbers are non-trivial, have them reviewed before you hit submit; an amended return invites scrutiny.
How does Small Business Relief work (revenue ≤ AED 3M)?
Small Business Relief is one of the most valuable provisions in the regime. If your revenue is AED 3 million or less for the tax period, you can elect to be treated as having zero taxable income — effectively paying 0% corporate tax. The key rules:
- You must actively elect for the relief on your return — it is not automatic.
- The AED 3 million threshold applies to revenue, not profit.
- You still must file a return — the election is made on the return itself.
- It is available for tax periods ending on or before 31 December 2026 (a temporary relief).
- It is not available to Qualifying Free Zone Persons or members of multinational enterprise groups.
- Tax losses from periods where relief was claimed cannot be carried forward.
Worked example — a consultancy with AED 2.5M revenue
• Revenue — AED 2.5M, which is under the AED 3M threshold.
• Profit before the election — say AED 600,000, which would otherwise be taxed at 9% on the amount above AED 375,000.
• With Small Business Relief elected — taxable income is treated as nil, so corporate tax due is AED 0.
• Catch — you still file the return, and you forgo carrying forward any loss from that period.
We handle the election for you
Our Basic plan (AED 249) includes the Small Business Relief election — we verify eligibility, make the election correctly on EmaraTax, and make sure you are not accidentally giving up loss carry-forward benefits you would rather keep.
How are free zone companies (QFZP) taxed on the return?
Free zone companies are taxable persons and must file — there is no automatic exemption. A company that meets the conditions to be a Qualifying Free Zone Person (QFZP) pays 0% on qualifying income, but the return is more involved:
- Qualifying income (from activities specified by the Ministry of Finance, with other free-zone persons or from foreign sources) is taxed at 0%.
- Non-qualifying income (certain mainland or excluded-activity income) is taxed at 9%.
- You must maintain adequate substance in the UAE — people, premises and expenditure that match your activities.
- Audited financial statements are mandatory for QFZPs regardless of revenue.
- Non-qualifying revenue must stay within the de minimis limit — the lower of AED 5 million or 5% of total revenue.
Losing QFZP status is costly
Breaching the de minimis limit or failing the substance requirement can cost you QFZP status for the current tax period and the following four — five periods at 9% instead of 0%. Get the qualifying-income analysis and the de minimis calculation right the first time. Comparing zones? The free-zone comparison tool is a useful starting point.
What other reliefs and deductions can you claim?
Beyond the small-business and free-zone regimes, several reliefs can materially reduce your tax — if you claim them correctly on the return.
| Relief / deduction | What it does | Key condition |
|---|---|---|
| Exempt income — dividends | Dividends from qualifying shareholdings are exempt | At least 5% participation |
| Exempt income — capital gains | Gains on disposal of qualifying shareholdings are exempt | 5% participation, held 12+ months |
| Foreign tax credit | Tax paid abroad offsets UAE tax on the same income | Capped at the UAE tax on that income |
| Tax loss carry-forward | Losses offset future taxable income | Up to 75% of taxable income per year; same entity |
| Group relief | Transfer losses between qualifying group companies | At least 75% common ownership; same financial year |
| Business restructuring relief | Tax-neutral mergers, demergers and intra-group transfers | Must meet the CT Law qualifying conditions |
What are the penalties for late filing or payment?
Corporate tax administrative penalties are set by Cabinet Decision No. 75 of 2023 (as amended). They compound quickly, which is why filing on time almost always costs less than the smallest penalty.
| Violation | Penalty | Example cost |
|---|---|---|
| Late filing of the return | AED 500/month (first 12 months), then AED 1,000/month | 6 months late = AED 3,000 · 18 months = AED 12,000 |
| Late payment of tax | Monthly penalty equal to 14% per year on the unpaid tax | AED 100,000 unpaid for 6 months ≈ AED 7,000 |
| Failure to keep required records | AED 10,000 (first), AED 20,000 (repeat within 24 months) | — |
| Filing an incorrect return | AED 500 fixed | Plus tax adjustments / interest on any shortfall |
| Failure to register for corporate tax | AED 10,000 | One-time |
✓ File on time
Return submitted and tax paid within 9 months of year-end. No penalties, no interest, a clean FTA record, and full access to reliefs and loss carry-forward. Cost: our fee from AED 249.
✗ Miss the deadline
AED 500/month building from day one, plus 14%-a-year late-payment penalty on any tax owed, plus the risk of an incorrect-return penalty if you rush. Six months of drift alone is AED 3,000 — before any tax.
Late to register? Check the waiver
The FTA has operated a waiver of the AED 10,000 late-registration penalty for businesses that file their first corporate tax return (or annual declaration) within 7 months of the end of their first tax period. If you registered late, confirm whether you qualify before paying anything — we can register you and check eligibility.
What are the 8 most common corporate tax return mistakes?
A short list of avoidable errors causes most penalties and overpayments. Check yourself against each before you file.
8 mistakes that cost money
• Not filing because “no tax is due” — the AED 500/month penalty does not care whether you owed anything.
• Misclassifying income — missing exempt income means overpaying; mislabelling non-qualifying income (free zone) means underpaying and penalties later.
• Forgetting to elect Small Business Relief — it is not automatic; miss the election and you are assessed at standard rates.
• Including non-deductible expenses — fines, penalties, most donations and excess entertainment reduce your computation below what it should be, inviting adjustments.
• Ignoring transfer pricing — related-party transactions must be arm’s length and disclosed; a master and local file are needed once standalone revenue reaches AED 200 million.
• Selecting the wrong tax period — especially for non-calendar years or short first periods, this cascades into deadline errors.
• Missing the payment deadline — filing and payment share a date; some file on time but forget to pay and trigger the 14% penalty.
• Losing QFZP status unknowingly — breaching de minimis or substance costs the 0% rate for five periods, often unnoticed until an FTA review.
