UAE Corporate Tax Guide for Small Businesses in 2026
The UAE introduced federal corporate tax on June 1, 2023 — a historic shift for a country that had been virtually tax-free for businesses for over five decades. For small and medium businesses in Dubai, the most critical development in 2026 is the approaching sunset of Small Business Relief on December 31, 2026, which means companies with revenue under AED 3 million will need to start computing and paying tax from 2027 onward. This guide covers everything a Dubai mainland business needs to know about corporate tax compliance in 2026.
UAE Corporate Tax Basics
Quick Answer: UAE Corporate Tax applies a 9% rate on taxable income exceeding AED 375,000 for all mainland and most free zone companies. Companies with revenue under AED 3 million can claim Small Business Relief (treating taxable income as zero) through December 31, 2026 only. All companies must register with the Federal Tax Authority regardless of revenue.
The Rate Structure
| Taxable Income Bracket | Tax Rate | |---|---| | Up to AED 375,000 | 0% | | Above AED 375,000 | 9% | | Qualifying Free Zone income | 0% (if conditions met) | | Large multinationals (global revenue EUR 750M+) | 15% (Pillar Two) |
The 0% threshold of AED 375,000 means a company with AED 500,000 in taxable income pays 9% only on the AED 125,000 above the threshold — which works out to AED 11,250. This makes the effective rate for small businesses significantly lower than the headline 9%.
Who Must Register
Every company operating in the UAE must register for Corporate Tax with the Federal Tax Authority (FTA), regardless of:
- Revenue level (even zero-revenue companies must register)
- Whether they qualify for Small Business Relief
- Whether they are mainland or free zone
- Whether they have taxable income
Registration is done through the EmaraTax portal (tax.gov.ae) and is free. The FTA assigns a Tax Registration Number (TRN) upon approval. Late registration triggers penalties under the new penalty regime effective April 2026.
Small Business Relief — Ending December 2026
Quick Answer: Small Business Relief allows companies with revenue of AED 3 million or less to treat their taxable income as zero — effectively paying no corporate tax. This relief is available only for tax periods ending on or before December 31, 2026. After that date, all companies regardless of size must compute and pay corporate tax normally.
Eligibility Requirements
To claim Small Business Relief for a tax period ending in 2026:
- Revenue must not exceed AED 3 million for the tax period
- Revenue must not have exceeded AED 3 million in any prior tax period since June 2023
- The company must be a resident person (UAE-registered entity)
- The company must not be part of a multinational enterprise group
- The company must not be a qualifying free zone person already benefiting from 0% rate
What "Revenue" Means
Revenue for the AED 3 million threshold is gross revenue — total income before deductions. It includes sales revenue, service fees, rental income, and any other operating income. It does not include capital gains from asset disposal or extraordinary items.
The 2027 Transition
When Small Business Relief expires on December 31, 2026, all companies must:
- Maintain proper accounting records (if not already doing so)
- Compute taxable income according to Federal Decree-Law No. 47 of 2022
- File tax returns within 9 months of their financial year end
- Pay any tax due within the same 9-month window
Companies that have been claiming Small Business Relief should begin preparing now — engage an accountant, set up proper bookkeeping, and understand which expenses are deductible to minimise their tax liability starting 2027.
Filing Deadlines and Requirements
Quick Answer: Corporate tax returns must be filed within 9 months of the end of the tax period. For companies with a December 31 financial year end, the filing deadline is September 30 of the following year. Late filing triggers penalties under the new regime effective April 2026.
Key Deadlines for 2026
| Event | Deadline | |---|---| | Tax registration (if not yet registered) | As soon as possible — penalties for late registration | | 2025 tax return filing (Dec year-end) | September 30, 2026 | | 2025 tax payment (Dec year-end) | September 30, 2026 | | 2026 tax return filing (Dec year-end) | September 30, 2027 | | Small Business Relief last available period | December 31, 2026 |
What to File
The tax return is submitted electronically through the EmaraTax portal. It includes:
- Financial statements (audited, for mainland companies)
- Tax computation showing adjustments from accounting profit to taxable income
- Details of any reliefs claimed (Small Business Relief, group relief, etc.)
- Transfer pricing documentation (if transactions with related parties)
The New Penalty Regime (April 2026)
Quick Answer: A harmonised penalty framework takes effect April 14, 2026 under Cabinet Decision No. 129 of 2025, aligning penalties across VAT, Excise Tax, and Corporate Tax. Late payment carries a flat 14% per annum (replacing the old 2% + 4% model), and incorrect returns cost AED 500 for a first violation and AED 2,000 for repeats.
Updated Penalties
| Violation | Old Penalty | New Penalty (April 2026+) | |---|---|---| | Late tax return filing | AED 500–1,000/month | AED 500 first time, AED 1,000 repeat | | Late payment | 2% immediate + 4%/month | 14% per annum (flat rate) | | Incorrect tax return | AED 500 | AED 500 first, AED 2,000 repeat | | Failure to keep records | AED 10,000 first | AED 10,000 first, AED 20,000 repeat | | Late registration | AED 10,000 | AED 10,000 | | Tax evasion | 100–300% of evaded tax | Criminal prosecution possible |
The shift from the old 2% + 4% late payment model to a flat 14% per annum is significant. For companies with tax liabilities of AED 100,000+, the annual penalty cost is now more predictable but still substantial.
FTA Enforcement
The FTA conducted 93,000 inspection visits in 2024 — a 135% increase from the previous year. Inspections cross-reference VAT returns with corporate tax returns to detect discrepancies. Companies that reported high VAT-able turnover but low corporate tax income are prime targets. The FTA has also begun requesting transfer pricing documentation from companies with related-party transactions.
Deductible Expenses
Quick Answer: Most ordinary business expenses are deductible for corporate tax purposes, including salaries, rent, professional fees, marketing costs, and depreciation. Non-deductible items include fines, penalties, donations to non-qualifying entities, and entertainment expenses exceeding 50% of the total.
Commonly Deductible Expenses
| Expense Category | Deductible? | Notes | |---|---|---| | Employee salaries and benefits | Yes | Including end-of-service gratuity provisions | | Office rent | Yes | Including Ejari-registered premises | | PRO and professional service fees | Yes | Including ZETUP retainer fees | | Marketing and advertising | Yes | | | Insurance premiums | Yes | Including mandatory health insurance | | Depreciation | Yes | As per accounting standards | | Bad debts | Yes | If genuinely written off | | Interest expense | Partially | Subject to thin capitalisation rules | | Entertainment | 50% | Only 50% deductible | | Fines and penalties | No | Government-imposed fines are not deductible | | Donations | Partially | Only to qualifying public benefit organisations | | Owner/shareholder salaries | Market rate | Must be at arm's length / market rate |
Transfer Pricing Rules
Companies with transactions between related parties (common in group structures) must ensure these transactions are priced at arm's length — meaning the price that would be agreed between independent parties. The FTA requires transfer pricing documentation for companies with:
- Revenue exceeding AED 200 million, OR
- Related party transactions exceeding AED 40 million
Even smaller companies should document related-party transactions to support their tax returns during potential audits.
Free Zone Corporate Tax
Quick Answer: Free zone companies can maintain a 0% corporate tax rate on qualifying income — income from transactions with other free zone companies or from international sources. Income from mainland UAE sources is taxed at 9%. Companies must meet substance requirements and elect for qualifying free zone person status.
Qualifying Conditions
To maintain the 0% rate, a free zone company must:
- Maintain adequate substance (employees, assets, expenditure) within the free zone
- Derive qualifying income (zone-to-zone or international transactions)
- Not have elected to be subject to the standard 9% rate
- Comply with transfer pricing requirements
- Maintain audited financial statements
- Not derive income from excluded activities (certain regulated financial activities)
What Does Not Qualify
Income from mainland UAE customers or clients is taxed at 9% even if the company is registered in a free zone. This is the single most misunderstood aspect of free zone taxation — the 0% rate is not automatic and does not apply to all free zone company income.
E-Invoicing Preparation
Quick Answer: The UAE is implementing mandatory e-invoicing starting 2027, with 2026 being the preparation and transition phase. Companies should begin evaluating their invoicing systems and ensuring compatibility with the FTA's e-invoicing framework.
The FTA has announced that electronic invoicing will become mandatory, with the system expected to follow a model similar to Saudi Arabia's FATOORAH platform. During 2026, companies should:
- Evaluate their current invoicing systems
- Identify gaps in e-invoicing readiness
- Begin discussions with their accounting software providers about compliance
- Monitor FTA announcements for technical specifications and timeline updates

Frequently Asked Questions
Q: Does my small company need to register for corporate tax? A: Yes. All UAE-registered companies must register with the FTA regardless of revenue or whether they qualify for Small Business Relief. Registration is free through the EmaraTax portal.
Q: What is the deadline for Small Business Relief? A: Small Business Relief is available for tax periods ending on or before December 31, 2026. After that date, all companies must compute and pay corporate tax normally, regardless of revenue.
Q: How is corporate tax different from VAT? A: VAT (5%) is a consumption tax charged on goods and services at the point of sale. Corporate tax (9%) is levied on the company's net profit (taxable income). They are separate obligations — a company may owe both VAT and corporate tax.
Q: Can I deduct my PRO service fees from taxable income? A: Yes. Professional service fees, including PRO retainers, are deductible business expenses for corporate tax purposes.
Q: What happens if I miss a filing deadline? A: Under the new penalty regime (April 2026), late filing costs AED 500 for the first occurrence and AED 1,000 for repeat violations. Late payment carries a 14% per annum penalty. These penalties compound — it is significantly cheaper to file on time.
Q: Do I need an auditor for corporate tax? A: Mainland companies are required to maintain audited financial statements for trade licence renewal purposes. These audited statements form the basis of the corporate tax return. Free zone audit requirements vary by zone.
Q: Is my revenue or my profit taxed? A: Profit (taxable income), not revenue. Taxable income is your revenue minus allowable deductions (expenses, depreciation, etc.). A company with AED 5 million in revenue but AED 4.8 million in expenses has taxable income of only AED 200,000 — below the AED 375,000 threshold, meaning zero tax.
Q: What records must I keep? A: All financial records, invoices, bank statements, contracts, and supporting documentation must be maintained for at least 7 years. Failure to maintain adequate records triggers penalties of AED 10,000 for a first violation and AED 20,000 for repeats.
Q: Are there any corporate tax exemptions? A: Government entities, government-controlled entities, extractive businesses (oil, gas, mining subject to emirate-level taxation), qualifying public benefit entities, and qualifying investment funds are exempt. For standard private sector companies, the 9% rate applies universally.
Q: Should I restructure my business for tax purposes? A: Potentially — companies with both mainland and international revenue may benefit from a dual-entity structure (mainland + free zone). However, restructuring must have genuine commercial substance, not just tax motivation. Consult a qualified tax advisor before making structural changes.
Q: How does ZETUP's corporate tax service differ from an accounting firm? A: We handle the government interface — FTA registration, portal management, filing submission, and deadline tracking. Your accountant handles the financial computation — preparing accounts, calculating taxable income, and determining the tax amount. We coordinate between you and your accountant to ensure everything reaches the FTA correctly and on time.
