UAE corporate tax applies to almost every business in the country, whether you run a mainland company, a free zone entity, or work as a freelancer above a certain income level. This guide walks through the rate, who has to register, the documents you need, current deadlines, penalties, and the reliefs most guides leave out, including free zone tax treatment and Small Business Relief.
Whether you run a small consultancy, a free zone trading company, or a larger group with several entities, the rules below apply to you in some form. Read the section that matches your situation, then use the checklist near the end before you file anything.
What is the UAE corporate tax rate
The UAE corporate tax rate is 0% on taxable income up to AED 375,000, and 9% on taxable income above that amount. This is a banded rate, not a flat one. A company with AED 500,000 in taxable profit pays 9% only on the AED 125,000 above the threshold, not on the full amount.
This applies to accounting profit as shown in your financial statements, adjusted for specific items the law sets out (such as certain exempt income and non-deductible expenses), not to raw revenue or turnover.
Do you actually need to register
Yes, almost certainly, and the profit level is not what decides it. Registration is required for nearly every taxable person in the UAE, including companies whose income falls entirely inside the 0% band. Being profitable below AED 375,000 does not exempt you from registering. It only means your tax bill for that period is zero.
The one group with a genuine income based trigger is individuals. A natural person (a freelancer or sole proprietor) only needs to register once their UAE business turnover passes AED 1 million in a calendar year. Below that figure, no registration is required.
If your business falls into one of the automatically exempt categories (covered further down), you may be excused from registration too, but this needs to be confirmed with the Federal Tax Authority (FTA) case by case, not assumed.
Free zone companies: the 0% rate most guides skip
Free zone status does not automatically mean 0% tax. A free zone company still has to register for corporate tax like any other business. It can access the 0% rate on qualifying income only if it becomes a Qualifying Free Zone Person (QFZP), which means meeting all of the following at once:
- It is legally established in a UAE free zone
- It keeps adequate staff, assets, and operations (substance) inside the free zone
- Its income counts as qualifying income under the rules (broadly, transactions with other free zone persons, qualifying activities with the mainland, and income from qualifying intellectual property)
- It has not chosen to opt into the standard tax regime instead
- It follows transfer pricing rules and keeps the required documentation
- Its non qualifying revenue stays under the limit (the lower of 5% of total revenue or AED 5 million)
- It prepares audited financial statements
Miss any one of these in a given tax period and the whole entity is taxed at the standard 9% rate (above AED 375,000) for that period, not just the non qualifying portion. This is the detail that trips up most free zone businesses, so if this applies to you, treat your QFZP conditions as something to check every year, not once at setup.
Small Business Relief: paying zero without the paperwork
If your total revenue is AED 3 million or less in the current and all previous relevant tax periods, you can elect Small Business Relief. Once elected, you are treated as having no taxable income for that period, meaning your corporate tax liability is zero.
A few things to know before you rely on this:
- It is not automatic. You must actively elect it when filing, through the EmaraTax portal.
- You still have to register and file a return. Small Business Relief removes the tax bill, not the filing obligation.
- Electing it means you give up other deductions, reliefs, and loss carry forwards for that period, so it is not always the best choice even if you qualify.
- This is a transitional measure. As things stand, it applies to tax periods ending on or before 31 December 2026, so businesses relying on it should plan for what comes after.
Choosing your tax residency and accounting period
Your tax residency in the UAE generally follows where your business is incorporated, managed, and controlled, or where you carry out your core operations. This affects which rules and filing obligations apply to you, so get this right before you register rather than after.
You also need to pick an accounting period, either:
- The Gregorian calendar year (January to December), or
- Any other 12 month period of your choosing
Whichever you pick, it has to stay the same every year going forward. Changing it later requires FTA approval, so choose based on how your business actually reports internally, not just habit.
Documents you need before you register
Have these ready before you start the EmaraTax application, since an incomplete submission just slows you down:
- Valid trade license (all licenses if you hold more than one)
- Memorandum of Association (MOA) or equivalent constitutional document
- Passport and Emirates ID copies of the owners, partners, and authorised signatory
- Proof of authorisation for whoever is signing (board resolution or power of attorney, where applicable)
- Contact details for the business and the authorised signatory
- Financial statements, for entities that already have them prepared
- For foreign documents, an attested copy from the relevant embassy, with a certified translation where needed
How to register: the actual steps
- Create or log into your account on EmaraTax (eservices.tax.gov.ae), using UAE Pass or your registered email.
- Start a new Corporate Tax registration application and select your entity type (mainland, free zone, natural person, and so on).
- Enter your trade license, ownership, and contact details, and upload the documents above.
- Submit the application and wait for the FTA to review it. Once approved, you receive your Tax Registration Number (TRN) for corporate tax.
- Keep your TRN and registration confirmation on file. You will need it for every future filing.
Registration and filing deadlines in 2026
Two separate deadlines matter here, and mixing them up is a common and costly mistake.
Registration deadline. New companies, mainland or free zone, must register within three months of incorporation. Businesses that existed before the corporate tax rules took effect had staggered 2024 deadlines based on their trade license issue month; if you have not registered yet and fall into that group, you are already late and should register immediately rather than wait.
Filing and payment deadline. Corporate tax returns and any tax owed are due within nine months of the end of your tax period. For example, if your financial year runs January to December 2025, your return and payment are both due by 30 September 2026. Filing without paying, or paying without filing, still counts as non compliance, so both steps need to happen together.
What is actually exempt from UAE corporate tax
The full list of exempt persons, correctly stated, is:
- UAE government entities and government controlled entities
- Businesses engaged in extractive activity (oil, gas, and other natural resource extraction) that meet the conditions set out in the law
- Businesses engaged in non extractive natural resource activity (processing, refining, storing, or distributing UAE natural resources) under similar conditions
- Qualifying public benefit entities (charities and similar organisations), once listed in a Cabinet Decision
- Qualifying investment funds
- Public or private pension and social security funds that are properly regulated
- Wholly owned UAE subsidiaries of the entities above, where the subsidiary exists only to support the exempt parent’s activities
Some of these exemptions are automatic (government entities), others need notification to the Ministry of Finance, and others need formal FTA approval (funds and pension schemes). Do not assume exemption. Confirm your category and its specific conditions before treating yourself as outside the tax net.
Dividends and capital gains are not automatically tax free
This is one of the most misunderstood parts of the law. Dividends, capital gains, and liquidation proceeds from a shareholding (called a Participating Interest) are only exempt if all of these conditions are met:
- You hold at least 5% of the company (or your acquisition cost was at least AED 4 million, if your stake is smaller)
- You have held it for at least 12 months, or genuinely intend to
- The company you hold shares in is taxed at 9% or more in its home country, or is subject to UAE corporate tax itself
- No more than half of that company’s assets would fail these same tests if you held them directly
If your holding does not meet these conditions, the dividend or gain is taxed as ordinary income. This is a common area where businesses assume exemption and get it wrong, so if you hold shares in a subsidiary or joint venture, this is worth reviewing with your advisor specifically, not assuming.
Penalties: what non compliance actually costs you
The FTA applies these penalties automatically once a deadline is missed, with no audit needed to trigger them:
- Late registration: AED 10,000, charged once.
- Late filing of your return: AED 500 per month for the first 12 months, rising to AED 1,000 per month after that, with no cap.
- Late payment of tax owed: roughly 14% annual interest on the unpaid amount, calculated monthly, from the due date until you pay in full.
- Failure to keep proper records: AED 10,000 for a first violation, rising to AED 20,000 if it happens again within 24 months. Records must be kept for at least seven years.
- Failure to provide information the FTA requests: AED 5,000.
The waiver most businesses do not know exists
If you missed your registration deadline and are sitting on (or already paid) the AED 10,000 penalty, you can still have it waived or refunded. The condition is straightforward: file your first corporate tax return, or your annual declaration if you are an exempt person, within seven months of the end of your first tax period. Meet that condition and the penalty is cancelled, or credited back to your EmaraTax account if you already paid it. This applies whether the penalty has already been issued, already been paid, or has not been imposed yet.
Large multinationals: the Domestic Minimum Top-up Tax
This does not apply to most businesses reading this guide, but it is worth knowing about if you are part of a larger international group. Multinational groups with global consolidated revenue above EUR 750 million are subject to a 15% Domestic Minimum Top-up Tax, in line with the OECD’s global minimum tax rules (Pillar Two). If your group operates well below that revenue level, this does not affect you.
Choosing a corporate tax advisor in the UAE
Not every accountant is qualified to advise on this. Before hiring anyone, check:
- Whether they are a Tax Agent registered with the FTA, not just a general accountant. Registered agents are listed on the FTA’s public register and have passed FTA requirements to represent taxpayers directly.
- Their actual experience with your situation. A free zone trading company, a holding structure, and a small service business need different expertise, and someone strong in one is not automatically strong in another.
- Whether they can show recent, specific experience with EmaraTax filings, not just general UAE company setup work.
- How they charge, and whether that includes ongoing filing support or just one off registration.
Good advice here is not optional if your structure is anything beyond a single simple mainland company. The cost of a wrong exemption claim or a missed QFZP condition is usually far higher than the advisor’s fee.
Your UAE corporate tax checklist
- Confirm whether you must register (almost every business must, regardless of profit level)
- Choose your tax residency and accounting period, and keep the period consistent every year
- Gather your trade license, MOA, ownership documents, and ID copies
- Register through EmaraTax and get your TRN, within three months of incorporation for new entities
- If you are a free zone company, check every QFZP condition, not just your license type
- If your revenue is AED 3 million or under, decide whether Small Business Relief actually benefits you
- Mark your filing and payment deadline: nine months after your tax period ends
- If you missed your registration deadline, file your first return within seven months of your first tax period end to qualify for the penalty waiver
- Keep full financial records for at least seven years
- Review any dividend or capital gains exemption claims against the actual participation exemption conditions, not assumptions
If you are not sure which of these rules apply to your business, speak with a registered tax agent before you file. A wrong exemption claim or a missed condition usually costs far more than the advice would.
