UAE corporate tax is now a settled feature of doing business: a 9 percent federal tax on profits above AED 375,000, a 0 percent band below, a free zone regime with conditions attached and a 15 percent top-up for the largest multinational groups. This guide is the map of the ATB Knowledge Series on the subject — where to start, what each piece covers and the order that makes sense — maintained as the regime has evolved through June 2026.
Foundations
Start here if the regime is new to you. These pieces establish who is taxed, on what, and at which rates — the vocabulary everything else assumes.
- What Is UAE Corporate Tax? — scope, rates and who falls within the net, from mainland companies to individuals in business.
- Corporate Tax in the UAE — the regime end to end: registration, computation, reliefs and the compliance cycle in one read.
- Exemptions and Reliefs — who sits outside the regime, and the reliefs that soften it for those inside.
Special Regimes and Situations
Most of the difficulty — and most of the planning value — lives in the special regimes. Read the pieces that match your structure.
- Free Zone Taxation Rules — qualifying income, the de minimis test and keeping the 0 percent rate once you have it.
- Small Business Relief — the AED 3 million election, and why its sunset after periods ending 31 December 2026 makes this the piece to read now.
- Foreign Companies and Permanent Establishments — when an overseas business is pulled into the UAE net, and what a PE changes.
- Holding Companies — the participation exemption and the design of UAE holding structures under the regime.
- QIF and Investment Manager Exemptions — fund vehicles, REITs and the carve-out that keeps UAE-based managers from creating PEs for foreign funds.
- E-commerce and Digital Businesses — how digital revenue, platforms and remote selling sit under corporate tax.
Compliance and Risk
The regime is administered through deadlines, documents and elections — and most penalties are process failures rather than technical ones.
- Filing and Deadlines — registration, the nine-month filing window and the calendar that keeps a business penalty-free.
- Tax Grouping: Benefits and Risks — when consolidation under 95 percent ownership helps, and the liabilities it binds the group to.
- Common Corporate Tax Mistakes — the recurring errors that actually trigger penalties, collected from practice.
Questions and Answers
For quick reference, the series includes a question-and-answer layer. The UAE Corporate Tax FAQ answers the fourteen questions businesses ask most, and audience-specific FAQs — for free zone entities, SMEs, freelancers, foreign companies, funds and UAE-incorporated businesses — go deeper on each profile. The service side of the same subject, from registration through filing, sits on our UAE Taxation page.
Where the Regime Stands in June 2026
Four developments frame the current year. Small Business Relief is in its final stretch, applying only to tax periods ending on or before 31 December 2026 with no extension announced. The 15 percent Domestic Minimum Top-up Tax now applies to groups with global revenue of EUR 750 million or more, for financial years starting on or after 1 January 2025. E-invoicing begins its phased rollout from July 2026. And the withholding rate on domestic and cross-border payments remains 0 percent — the feature that keeps the UAE distinctive even as the rest of the regime matures. The series pieces above are updated to reflect all four.
Frequently Asked Questions
Where should a new reader start?
With the Foundations group — in particular What Is UAE Corporate Tax? — and then the one special-regime piece that matches your structure: free zone rules for free zone entities, the PE piece for foreign groups, Small Business Relief for small residents. Two articles in, the FAQ layer fills the gaps.
How current is the series?
Each piece carries its publication date and was updated in June 2026 to reflect the Small Business Relief sunset, the Domestic Minimum Top-up Tax, the 2025 changes to fund and REIT conditions and the July 2026 start of e-invoicing. Where rules are expected to move again, the articles say so rather than pretending permanence.
Does reading this replace advice?
No. The series explains how the regime works in general; positions on qualifying status, elections, groups and cross-border facts turn on details that general commentary cannot see. Use the guide to ask better questions — and take specific advice before acting on the answers.
