How to prepare your business tax filing in the UAE

With a well-organized approach, preparing business taxes in the UAE can be completed smoothly and ensure a smooth filing process while minimizing compliance risk.

Step 1: Determine your tax obligation: Before starting your business tax preparation in the UAE, assess whether your business is required to file for Corporate Tax.

Most UAE businesses must register for Corporate Tax unless specifically exempt.

Businesses with annual revenue of AED 3 million or below may elect for Small Business Relief, subject to eligibility conditions. Under this relief, taxable income is treated as zero; however, filing a Corporate Tax return remains mandatory.

Step 2: Register on the EmaraTax portal: Register your business on the EmaraTax platform, the UAE FTA online system for all corporate tax activities. This is a mandatory step in the business tax preparation process.

Step 3: Keep up-to-date financial records: Maintain all income, expenses, and transactions properly recorded to ensure accurate tax calculation and compliance with UAE FTA regulations.

Step 4: Compute taxable income: Calculate your taxable income after deducting allowable expenses from total revenue. 

• Income up to AED 375,000 is taxed at 0%
• Income exceeding AED 375,000 is taxed at 9%.

Step 5: Finalize your corporate tax filing: Log in to EmaraTax and prepare your corporate tax return by reporting income, claiming eligible deductions, and verifying your tax payable. This is a key stage in business tax preparation in the UAE.

Step 6: Keep track of your filing deadline: Ensure your business tax return is submitted within 9 months from the end of the financial year.

For example, a December 31, 2025, year-end requires filing by September 30, 2026.

Step 7: Settle your dues on time: Once your tax liability is verified, make the payment through the EmaraTax portal before the filing deadline to avoid penalties.

Step 8: Retain and organize supporting documents: Retain all financial documents, including invoices and bank statements, to ensure readiness for FTA audits and verification.
