If you run a business in the UAE, corporate tax UAE rules now affect almost every company, from mainland LLCs to freezone startups. Since the Federal Decree-Law No. 47 of 2022 came into force, businesses of nearly every size must register, and many must file and pay even when their tax bill is zero. This guide breaks down exactly what it means for your business, who must comply, and the steps to stay on the right side of the Federal Tax Authority (FTA).
What Is Corporate Tax in the UAE?
Corporate tax UAE is a federal tax on the net profit of businesses, introduced under Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses. It applies to tax periods starting on or after 1 June 2023 and is administered by the FTA through the EmaraTax platform.
The headline structure is straightforward: 0% applies to taxable income up to AED 375,000, and 9% applies to taxable income above that threshold. This makes the UAE’s corporate tax UAE regime one of the more competitive systems globally, while still bringing the country in line with international tax transparency standards.
Who Does This Apply To?
This tax applies broadly to:
Mainland companies of every size and sector, holding companies and investment vehicles, freezone companies (even those eligible for 0% on qualifying income still must register and file), and natural persons (individuals, including freelancers and sole establishment owners) whose turnover from business activity exceeds AED 1 million in a Gregorian calendar year.
A small number of entities are exempt, including qualifying government entities, qualifying public benefit organisations, qualifying investment funds, and certain extractive/non-extractive natural resource businesses already subject to Emirate-level taxation. Exempt status is not automatic for most categories — it generally must be confirmed with the FTA.
Key Rules & Requirements
The FTA has issued detailed guidance on registration timeframes, rates, and reliefs. The core rules every business should know:
Tax rate: 0% on the first AED 375,000 of taxable income, 9% on the excess, for standard taxable persons.
Free Zone Persons: A Qualifying Free Zone Person can apply a 0% rate to “qualifying income” if it maintains adequate substance in the UAE, earns qualifying income, meets the de minimis requirement, has not elected to be taxed as a mainland business, and complies with transfer pricing rules. Income that falls outside these conditions is taxed at the standard 9% rate.
Small Business Relief: Resident taxable persons with revenue at or below AED 3 million can elect to be treated as having no taxable income for that period, as a transitional measure available for tax periods ending on or before 31 December 2026.
Registration deadlines: Per FTA Decision No. 3 of 2024, businesses licensed before 1 March 2024 had deadlines based on their month of license issuance (for example, licenses issued in January or February had to register by 31 May 2024). Entities incorporated on or after 1 March 2024 must register within three months of incorporation. Resident natural persons whose turnover exceeded AED 1 million in a given Gregorian year must register by 31 March of the following year — so 2025 turnover above the threshold means registration was due by 31 March 2026.
Filing and payment: Corporate Tax returns and any tax due must be submitted within nine months of the end of the relevant tax period. For a calendar-year tax period ending 31 December 2025, the return and payment are due by 30 September 2026 — a deadline many businesses are approaching right now.
Penalties: Missing the registration deadline triggers a flat AED 10,000 penalty. Late filing is penalised at AED 500 per month for the first 12 months, rising to AED 1,000 per month thereafter. Under Cabinet Decision No. 129 of 2025, effective 14 April 2026, the late-payment penalty framework was restructured to an annualised rate charged from the due date. The FTA has also run a registration penalty waiver initiative for businesses that file their first return within seven months of their first tax period ending — worth checking if you registered late.
Step-by-Step Guide to Corporate Tax Compliance
Whether you’re registering for the first time or preparing your first return, follow these steps:
1. Confirm your taxable person status. Determine if your business is a Resident Person, Non-Resident Person, or natural person under the Corporate Tax Law, and whether any exemption applies.
2. Register on EmaraTax. Create or log into your EmaraTax profile at eservices.tax.gov.ae, select Corporate Tax registration, and submit your trade license and ownership documents. The process typically takes about 30 minutes across four steps.
3. Determine your tax period and financial year. Most businesses use the Gregorian calendar year, but you can align your tax period with your existing financial year if different.
4. Assess your eligibility for reliefs. Check whether Small Business Relief, Qualifying Free Zone Person status, or any exemption reduces your taxable income or rate.
5. Maintain proper accounting records. Keep audited or reviewed financial statements (where required) and supporting records for at least seven years, as the FTA can request these during an audit.
6. Calculate taxable income. Start from accounting profit and apply the adjustments set out in the Corporate Tax Law (disallowed expenses, exempt income, transfer pricing adjustments).
7. File your return and pay on time. Submit your Corporate Tax return through EmaraTax and settle any liability within nine months of your tax period’s end.
Practical Tips to Stay Compliant
Treat corporate tax UAE compliance as an ongoing process, not a once-a-year task. Reconcile your books monthly rather than scrambling before the filing deadline. Keep your trade license, Memorandum of Association, and ownership structure documents up to date in EmaraTax, since mismatches commonly cause registration delays. If you operate in a freezone, document your substance and qualifying income carefully — this is the area FTA audits scrutinise most closely. Finally, calendar your registration, filing, and payment deadlines well in advance, since these penalties accrue automatically and apply even when no tax is ultimately owed.
Common Mistakes to Avoid
The most frequent corporate tax UAE errors businesses make include: assuming a 0% rate eligibility means no registration is needed (registration is still mandatory); missing the natural-person turnover threshold because personal and business income weren’t tracked separately; underestimating how long document collection takes before the EmaraTax deadline; failing to elect Small Business Relief in time despite qualifying; and treating freezone “tax-free” status as automatic rather than conditional on meeting all five Qualifying Free Zone Person requirements every year.
Frequently Asked Questions
Do all UAE companies need to register for corporate tax UAE, even if they expect to pay 0%?
Yes. Registration is mandatory for almost all taxable persons regardless of expected tax liability, including freezone companies and businesses under the AED 375,000 threshold.
What happens if I miss the registration deadline?
The FTA imposes a flat AED 10,000 administrative penalty for late registration, separate from any late filing or late payment penalties.
Can a small business avoid paying tax entirely?
Businesses with revenue at or below AED 3 million may elect Small Business Relief and be treated as having no taxable income, but this is a transitional measure with an end date, not a permanent exemption.
How long do I have to file and pay after my tax period ends?
Nine months from the end of your tax period. For a calendar-year business with a tax period ending 31 December 2025, the deadline is 30 September 2026.
