UAE Corporate Tax Guide 2026: Everything Businesses Need to Know

The UAE introduced a federal corporate tax of 9% on business profits above AED 375,000 — a landmark shift after decades of zero-tax operation. For 2026, the compliance calendar is now firmly part of running any UAE company, including most Free Zone entities. This guide covers everything founders need to know to stay compliant.

Corporate Tax at a Glance

• 0% tax on taxable income up to AED 375,000
• 9% tax on taxable income above AED 375,000
• 0% rate for Qualifying Free Zone Persons on qualifying income
• No tax on qualifying dividends and capital gains (with conditions)
• Financial year can be calendar year or any 12-month period

Who Must Register and File

All UAE companies — Mainland, Free Zone, and certain branches — must register with the Federal Tax Authority (FTA) for corporate tax, even if they expect zero taxable income. Registration deadlines are tied to your licence issuance date, and late registration carries penalties starting at AED 10,000.

Sole proprietorships and natural persons earning below AED 1 million annually are generally exempt, but the rules have nuances around multiple licences and related-party income. We review your structure at setup to confirm your obligations from day one.

Filing Deadlines for 2026

Filing deadlines fall nine months after the end of your financial year. For a calendar-year company, the return covering 2025 is due by 30 September 2026. Late filing penalties begin at AED 500 per month and can compound quickly.

Provisional returns are not required — but maintaining quarterly internal accounts makes the annual filing a straightforward exercise rather than a year-end scramble. We recommend setting up cloud accounting (Xero, Zoho Books, or QuickBooks) from your first transaction.

Free Zone 0% Rate Rules

Qualifying Free Zone Persons (QFZPs) can still access a 0% rate on qualifying income — but the qualification rules are strict. You must maintain adequate substance in the UAE, prepare audited financial statements, and adhere to transfer pricing documentation requirements.

Non-qualifying income — such as revenue from mainland UAE customers without a qualifying structure — is taxed at 9%. De minimis rules allow up to 5% of total revenue or AED 5 million (whichever is lower) from non-qualifying sources while retaining QFZP status.

Common Deductions and Exemptions

• Business expenses wholly and exclusively incurred for business purposes
• Depreciation on qualifying assets
• Interest expenses (subject to thin capitalisation rules)
• Charitable donations to approved UAE entities
• Losses carried forward for up to 75% of future taxable income

Penalties for Non-Compliance

• Late registration: AED 10,000
• Late filing: AED 500 per month (first 12 months), then AED 1,000 per month
• Late payment: 14% per annum interest on unpaid tax
• Inaccurate returns: AED 500 to AED 20,000 depending on severity

Practical Steps for Founders

Start with proper bookkeeping from your first transaction. Separate personal and business accounts. Keep invoices, contracts, and expense receipts organised. Appoint a tax agent if your annual turnover exceeds AED 50 million.
