Quick Answer: UAE businesses are required to register for corporate tax through the Federal Tax Authority via the EmaraTax portal.
Tax is charged at 9% on taxable income above AED 375,000. Missing deadlines in 2026 can trigger FTA penalties starting at AED 10,000. Registration is compulsory even if your business has not yet turned a profit.
2026 marks a turning point for corporate tax compliance in the UAE. The regime is fully operational, enforcement is active, and businesses that have been slow to act are now facing real consequences.
Whether your company operates on the mainland or within a free zone, getting your corporate tax registration sorted, knowing exactly when your returns are due, and understanding what penalties look like in practice is no longer something you can put off.
This guide walks you through each of those areas clearly, including the registration process, 2026 filing deadlines, the 9% tax bracket, free zone exemption rules, and a practical checklist you can use right now.
What Is UAE Corporate Tax?
The UAE introduced a federal corporate tax framework under Federal Decree-Law No. 47 of 2022. The law took effect for financial years starting on or after June 1, 2023, and is administered by the Federal Tax Authority in coordination with the Ministry of Finance.
The core facts every business owner should have front of mind:
The standard rate is 9%, applied to taxable income above AED 375,000. Any income below that threshold is taxed at 0%. Businesses with annual revenue under AED 3 million may qualify for Small Business Relief, which remains available through the 2026 tax period.
Free zone businesses can access a 0% rate on qualifying income, but only if they meet the criteria set out for Qualifying Free Zone Persons. Natural resource extraction businesses sit outside the federal regime and continue to be taxed at the emirate level.
Who Needs to Register?
Corporate tax registration in the UAE applies to a broad range of entities:
Mainland companies and their UAE branches. Free zone entities, including those seeking exemption treatment. Foreign businesses with a permanent establishment in the UAE. Individuals operating a trade-licensed business in the UAE.
The registration requirement is not linked to profitability. A business that earns nothing, or one that qualifies for Small Business Relief, still has a legal obligation to register and file. Skipping registration triggers an immediate penalty of AED 10,000.
How to Register: The EmaraTax Portal Login Process
All corporate tax registration is completed digitally through the EmaraTax portal at emaratax.tax.gov.ae. Here is how the process works:
Step 1 — Access the portal using your UAE Pass or your existing FTA login credentials.
Step 2 — From your dashboard, select the option to register for corporate tax.
Step 3 — Enter your business information: trade license details, financial year start date, and ownership structure.
Step 4 — Upload the required documents. These typically include a copy of your trade license, your Memorandum of Association, passport and Emirates ID copies for all owners, and audited financials where available.
Step 5 — Submit the application. Once reviewed and approved, the FTA issues your Tax Registration Number. This process generally takes between 5 and 20 business days depending on the nature of the application.
Step 6 — Your TRN becomes your reference point for all future filings, FTA correspondence, and relevant invoicing.

UAE Corporate Tax Deadlines 2026: The Dates That Matter
Filing and payment deadlines in the UAE are tied directly to your financial year-end. The FTA requires that corporate tax returns and any tax due be submitted within 9 months of the close of the relevant tax period.
Financial Year End | Return & Payment Due |
31 December 2024 | 30 September 2025 |
31 May 2025 | 28 February 2026 |
30 June 2025 | 31 March 2026 |
31 December 2025 | 30 September 2026 |
31 March 2026 | 31 December 2026 |
If your year-end falls on a date not listed above, add 9 months to it. That is your deadline.
Registration deadlines follow a similar logic and vary by business category. Any business that has not yet registered should do so without delay. Late registration alone attracts a minimum penalty of AED 10,000.
QuickPlus tracks all 2026 corporate tax deadlines across our client portfolio and sends reminders well ahead of each due date.
FTA Corporate Tax Penalties: What Non-Compliance Costs
The Federal Tax Authority applies penalties consistently. Below is a straightforward breakdown of what businesses risk in 2026.
Violation | Penalty |
Failure to register for corporate tax | AED 10,000 |
Late filing | AED 500/month for first 12 months, then AED 1,000/month |
Failure to maintain required records | AED 10,000 (first offence), AED 20,000 (repeat) |
Failure to submit audited financials when required | AED 10,000 |
Submitting incorrect information to the FTA | Minimum AED 1,000, higher depending on severity |
Late payment of tax due | 2% monthly on the outstanding amount |
Obstructing a corporate tax audit | Minimum AED 20,000 |
It is worth noting that the monthly filing penalty and the 2% late payment charge can run simultaneously. A business that misses both its filing and payment deadline does not face one or the other, it faces both at once.
Free Zone Corporate Tax Exemptions: Who Qualifies?
Free zone businesses are not automatically exempt from corporate tax. To benefit from free zone corporate tax exemptions and be treated as a Qualifying Free Zone Person (QFZP), a business must meet all of the following conditions as set out in Ministry of Finance (MoF) guidelines:
- Maintain adequate substance in the UAE free zone
- Derive income only from Qualifying Income sources as defined by MoF guidelines
- Not elect to be subject to the standard CT regime
- Comply with transfer pricing rules
- Prepare audited financial statements
QFZPs are subject to 0% corporate tax on Qualifying Income and 9% on non-qualifying income. If a free zone business fails to meet any of the QFZP conditions in a given tax period, it loses the exemption for that period and is taxed at the standard 9% rate on all taxable income.
Mainland tax compliance Dubai rules do not apply to free zone entities, but free zone businesses must still register, file, and comply with all FTA reporting requirements.
How the Corporate Tax Assessment Process Works
The UAE corporate tax system operates on a self-assessment basis. Businesses calculate their own taxable income, apply the applicable rate, and submit their return through the EmaraTax portal.
The FTA reviews submitted returns and may request further information or supporting documents during the assessment window. It also has the authority to conduct formal audits of any registered taxpayer, examining financial records, transfer pricing documentation, and the accuracy of what was filed.
Businesses are required to retain all financial records for a minimum of seven years to satisfy audit requirements.
If an error is discovered after a return has been filed, an amended return can be submitted through the portal. Voluntary disclosure made before the FTA initiates an inquiry can reduce the penalties applied.
Corporate Tax Deregistration: When and How to Do It
If your business closes, is dissolved, or no longer qualifies for corporate tax registration, you are required to formally deregister with the FTA. Leaving a registration open with unfiled returns will continue generating late filing penalties against the entity.
The deregistration process involves the following steps:
Confirm that all outstanding returns are filed and all tax balances are cleared. Log in to the EmaraTax portal and submit a deregistration application along with supporting documentation, including your trade license cancellation certificate. Wait for FTA approval. Once granted, your Tax Registration Number will be formally closed.
QuickPlus handles corporate tax deregistration for businesses winding down their UAE operations.
