Top 5 Tax Mistakes UAE Businesses Need to Avoid

May 9, 2025

The UAE’s tax landscape has evolved significantly in recent years, with the introduction of Value Added Tax (VAT) and, more recently, Corporate Tax. Navigating these regulations can be complex, and even well-intentioned businesses can stumble into costly errors. To help you stay compliant and avoid penalties, we’ve compiled the top 5 tax mistakes UAE businesses should be vigilant about.

1. Incorrect VAT Registration and Deregistration:

VAT registration is mandatory for businesses exceeding a certain threshold (currently AED 375,000 annual taxable supplies) and optional below it. Many businesses either delay registration when they should be registered, leading to penalties, or fail to deregister when their taxable supplies fall below the deregistration threshold (AED 187,500).

  • Mistake: Not monitoring turnover regularly and failing to register or deregister for VAT at the appropriate time.
  • Impact: Penalties for late registration or continued registration when no longer required, leading to unnecessary compliance burdens.
  • Tip: Implement a system to track your taxable supplies monthly and compare them against the registration and deregistration thresholds.

2. Errors in VAT Record Keeping and Documentation:

Maintaining accurate and complete records is crucial for VAT compliance. This includes tax invoices, credit notes, import/export documents, and accounting records. Failure to keep proper documentation can lead to difficulties during tax audits and potential penalties.

  • Mistake: Incomplete or inaccurate record-keeping, missing essential details on tax invoices, or not retaining documents for the mandatory period (currently five years).
  • Impact: Inability to substantiate input tax claims, leading to disallowance of deductions and penalties during audits.
  • Tip: Implement a robust record-keeping system, train staff on the importance of accurate documentation, and ensure all tax invoices contain the required details (e.g., supplier and recipient details, VAT registration numbers, description of goods/services, VAT rate, and amount).

3. Incorrect Application of VAT Rates and Exemptions:

The standard VAT rate in the UAE is 5%, but certain goods and services are subject to a 0% rate or are exempt. Misclassifying supplies can lead to incorrect VAT calculations and potential penalties.

  • Mistake: Applying the standard rate to zero-rated or exempt supplies, or vice versa. Common areas of confusion include exports, certain healthcare services, and specific financial services.
  • Impact: Overpayment or underpayment of VAT, leading to financial losses or penalties.
  • Tip: Stay updated on the official VAT legislation and guidelines issued by the Federal Tax Authority (FTA). Seek clarification when unsure about the VAT treatment of specific goods or services. For instance, residential properties are generally exempt from VAT, while commercial properties are subject to the standard rate.

4. Non-Compliance with Corporate Tax Obligations:

The introduction of Corporate Tax in the UAE has brought a new set of compliance requirements. Businesses need to understand their tax residency, taxable income, and the process for filing tax returns and making payments.

  • Mistake: Failing to understand the scope of Corporate Tax, not registering for Corporate Tax within the stipulated timeframe, or incorrectly calculating taxable income by not considering allowable deductions and exemptions.
  • Impact: Penalties for late registration, late filing of tax returns, and underpayment of tax.
  • Tip: Familiarize yourself with the Corporate Tax Law and related regulations. Determine your tax residency and understand how to calculate your taxable income. Seek professional advice to ensure compliance. For example, free zone entities might be subject to different Corporate Tax rules than mainland companies.

5. Ignoring Tax Agent Requirements and Deadlines:

The FTA allows businesses to appoint tax agents to assist with their tax obligations. However, businesses remain ultimately responsible for compliance. Missing deadlines for VAT returns, Corporate Tax returns, or payments can result in penalties.

  • Mistake: Assuming that appointing a tax agent absolves the business of all responsibility or failing to adhere to the prescribed timelines for filing and payments.
  • Impact: Penalties for late filing and payments, even if a tax agent is appointed.
  • Tip: Understand the deadlines for all tax obligations and ensure timely submission of returns and payments. Maintain clear communication with your tax agent and actively oversee the compliance process. For instance, VAT returns are typically due on a quarterly basis, while the Corporate Tax return deadline will be specified in the relevant legislation.

By being aware of these common tax mistakes, UAE businesses can take proactive steps to ensure compliance, avoid penalties, and foster sustainable growth in the evolving tax landscape.
