Dubai is a great place to start your business! To open a company on the mainland, you need a license from the Department of Economy and Tourism (DET). But, you must avoid common DET license application mistakes that can cause serious delays. Even with the new 2025 digital tools and the simple e-services portal, many people still make these errors.
These Dubai company formation mistakes often lead to your application getting rejected, which wastes your time and money. Knowing about common DET application errors helps you get it right the first time. This lets you launch your business much faster.
This guide provides fresh tips for November 2025. We will show you eight big blunders to sidestep for a quick approval process. Let’s get you ready for a successful business setup in Dubai and help you learn how to avoid DET license rejection.
Understanding DET License Application Mistakes to Avoid
A key DET license application mistake to avoid is not understanding its importance for your business. The Department of Economy and Tourism (DET) license allows you to operate legally on the Dubai mainland. With the February 2025 launch of the updated DET e-services portal, the application process is now digital, but this has also led to stricter checks on all documents you submit.
The DET offers different licenses based on your business activities:
- Commercial licenses are for trading goods and services.
- Professional licenses are for service-based professionals and artisans.
- Industrial licenses are for manufacturing and industrial companies.
- Tourism licenses are for businesses in the hospitality and tourism sector.
Making Dubai trade license application mistakes can be very expensive. A simple error might cause immediate rejection, meaning you must reapply and pay more government fees.
These delays can postpone your business launch and create problems with visa processing and getting your initial approval. Incorrect business setup can also lead to legal issues down the line.
Common DET application errors include submitting incomplete documents, choosing the wrong business activity, or violating trade name rules.
The 2025 digital system quickly finds these problems, making the process tougher than before. Dubai has high standards to ensure all businesses are legitimate, which builds trust with investors. Knowing about these common mistakes in Dubai business setup greatly improves your chances of getting your license approved without any issues.
8 DET License Application Mistakes to Avoid
1. Selecting Incorrect or Misaligned Business Activities
Choosing the wrong business activities is a primary reason for DET license rejection. The DET has a detailed list of approved activities, and yours must match your actual business operations.
A common wrong business activity on DET application mistake is picking vague descriptions or too many unrelated activities. This can lead to immediate rejection or future compliance problems.
Misalignment can also bring fines from AED 5,000 to AED 50,000 and even license suspension. To avoid these Dubai trade license application problems, research the DET activity list thoroughly.
Consulting with business setup experts can help you align your business plan with the right activities from the start, preventing common mistakes in Dubai business setup.
2. Submitting Incomplete or Inaccurate Documentation
Submitting incomplete DET license documents is another frequent error that causes delays. Your application requires valid passport copies, an Emirates ID for residents, a business plan, a signed Memorandum of Association (MOA), and an Ejari-registered tenancy contract.
Missing any of these, or providing expired documents, unclear copies, or information that doesn’t match across forms, will get your application flagged.
The 2025 DET e-services portal automatically detects such common DET application errors, leading to instant rejection. This means you have to restart the process, causing significant setbacks.
To prevent incorrect information on your trade license application, double-check that all documents are complete, accurate, and correctly formatted before you submit them.
3. Violating Trade Name Reservation Rules and Regulations
Dubai has strict rules for trade names, and you must reserve yours through the DET portal. Your name cannot be offensive, similar to an existing company, or contain words like “Global” or “International” without proper justification.
A frequent mistake is not researching name availability, which is a common reason for trade license rejection in Dubai. If your name is rejected, your application could be delayed by at least 3-7 days.
To avoid this, search the DET portal and prepare three to five alternative names. A trade license application checklist for Dubai should always include this step.
Approved trade names are reserved for 180 days, and you must use them within this period. This will help you learn how to avoid DET license rejection and keep your application moving smoothly.
4. Failing to Obtain Proper Initial Approval
Getting initial approval is a preliminary step that validates your business idea before you get your final license. This approval confirms your business activities, trade name, and general compliance. One of the most significant DET initial approval mistakes is signing an office lease or spending money on marketing before getting this confirmation. This can be a costly professional license application pitfall if your plan is not approved.
The initial approval is valid for 180 days, and you must complete your licensing within this time. You apply through the DET e-services portal by submitting your initial documents. Rushing this step can lead to problems later on, so taking the time to get it right is key to avoiding delays in the DET license process.
5. Not Meeting Physical Office Space and Ejari Requirements
Most businesses on the Dubai mainland need a physical office space with a valid commercial tenancy contract. This contract must be registered with Ejari, Dubai’s official rental registration system.
A common Dubai mainland license error is trying to use a residential address for a commercial business or relying on a virtual office when a physical one is required. These actions can cause your application to be rejected instantly.
Your office space must also have the correct permissions for your business activities. The DET portal now verifies Ejari details automatically, making it easy to spot fake addresses.
Securing a compliant office space before you apply is one of the most important steps to avoid common mistakes in Dubai business setup and prevent delays.
6. Choosing the Wrong License Type or Business Jurisdiction
Choosing the right jurisdiction is key to your business’s success. A mainland license lets you trade anywhere in the UAE and work with local markets, which is a major advantage over a free zone license.
One of the most common pitfalls when applying for a DET license is choosing a free zone when your business needs direct access to the mainland market. This is a serious Dubai company formation mistake that can limit your growth and lead to expensive restructuring later.
While most mainland activities now offer 100% foreign ownership, some still have different rules, so it is a good idea to seek professional guidance for your DET license application.
Before you decide, think about your target customers, ownership preferences, and future plans to make the best choice for your business.
7. Neglecting Additional Regulatory Approvals and Compliance Requirements
Many business activities in Dubai need extra approvals from specialized government bodies. For example, healthcare businesses need a permit from the Dubai Health Authority (DHA), while food-related businesses need one from the Food Safety Department.
A common reason for trade license rejection in Dubai is starting operations before getting all the necessary permits. This can lead to big fines from AED 10,000 to AED 100,000 or even license cancellation.
The 2025 DET portal helps by giving better guidance on these extra approvals during your application. To avoid problems, identify all required approvals early and apply for them at the same time as your DET license.
This will prevent common DET application errors and keep your business setup on track.
8. Attempting Complex Applications Without Professional Guidance
While the 2025 DET e-services portal has made applying easier, the rules are still complex. Many entrepreneurs face challenges with technical Arabic terms, different government portals, and understanding all the requirements.
A common do-it-yourself mistake is misinterpreting activity descriptions, which can lead to application rejection and add two to four weeks to your timeline.
Getting professional guidance for your DET license application can help you avoid these issues. Experts can ensure you choose the right activities, prepare accurate documents, and navigate the approval process smoothly.
The cost of these services is often balanced by the time you save and the errors you prevent, making it a smart way of avoiding delays in the DET license process.
What to Do If Your DET Application Gets Rejected?
If your DET application is rejected, don’t worry—most rejections can be fixed. First, you need to know what to do if your DET application is rejected by carefully reviewing the detailed rejection notes in the DET e-services portal.
The updated 2025 system provides clear reasons, helping you understand if the problem is with your documents, business activity choice, or trade name.
Once you identify the root cause, you can start fixing the errors on your DET application. Gather the correct documents, choose a different business activity, or select a new trade name based on the feedback.
If the rejection is complex, consider consulting with a business setup expert who can help you avoid making the same mistake again. After making the necessary corrections, you can resubmit your application through the portal.
Understanding the reasons for trade license rejection in Dubai will not only help you get your license but also prevent future issues.
