How to Verify a Business Tax Number in the UAE

Verifying a business tax number in the UAE is essential to confirm that the entity you are dealing with is properly registered for tax purposes. This ensures your business transactions comply with tax laws, preventing errors in VAT claims and avoiding fraudulent dealings. This article guides you through the verification process with clear, practical steps and a worked example.

Why this comes up / what goes wrong

Small business owners in the UAE often need to verify a business tax number to confirm that their suppliers, customers, or partners are registered with the Federal Tax Authority (FTA). Without verification, you risk:

• Paying businesses that are not registered for VAT or other taxes, which can affect your VAT Input Tax Credit (ITC) claims.
• Filing incorrect tax returns due to invalid or inactive tax numbers.
• Experiencing delays in payments or disputes due to unverified tax details.

Many businesses receive tax numbers on invoices or contracts but do not know how to check their authenticity. This can lead to rejected VAT returns or compliance issues.

Step-by-step

1. Obtain the Tax Number (TRN)

• Locate the 15-digit Tax Registration Number on the invoice, contract, or official document from the business.
• Confirm the number has exactly 15 digits.

1. Go to the FTA Verification Portal

• Visit the official UAE Federal Tax Authority website.
• Find the Tax Registration Number verification page or service.

1. Enter the Tax Number

• Input the full 15-digit TRN carefully.
• Double-check for typos or missing digits before submitting.

1. Review the Verification Result

• The portal will confirm if the TRN is valid and active.
• It will display the registered business name and the status of the tax registration.

1. Save the Verification Proof

• Take a screenshot or download the verification confirmation.
• Keep this record for your accounting or audit purposes.

1. If the TRN is Invalid or Inactive

• Contact the supplier or partner to clarify or request a valid TRN.
• If needed, reach out to the FTA helpline for support.

1. Integrate Verification into Your Workflow

• Use a CRM system like HelloGrowthCRM for the United Arab Emirates to store verified tax numbers alongside your customer and supplier records.

Example (fictional figures)

An interior fit-out contractor in Sharjah receives an invoice from a supplier showing the TRN 100123456700003. The invoice amount is AED 48,000 plus VAT at an assumed illustrative rate of 5%.

• Step 1: The contractor notes the TRN: 100123456700003.
• Step 2: They visit the FTA website and navigate to the TRN verification portal.
• Step 3: They enter the TRN 100123456700003.
• Step 4: The portal confirms the TRN is valid and active, registered under “Sharjah Interiors LLC.”
• Step 5: The contractor saves a screenshot of this verification.

Calculating VAT:

AED 48,000 × 5% = AED 2,400 (VAT amount)

Total invoice amount including VAT:

AED 48,000 + AED 2,400 = AED 50,400

With the verified TRN, the contractor can confidently claim the VAT Input Tax Credit for AED 2,400 in their VAT return.

Common mistakes

• Entering incorrect or incomplete TRN: Always verify the full 15-digit number carefully to avoid false invalid results.
• Skipping verification: Not verifying the TRN risks dealing with unregistered businesses and potential compliance issues.
• Relying on outdated verification: TRNs can be suspended or cancelled; verify before each major transaction.
• Ignoring verification details: Confirm the business name and status match your supplier to avoid fraud.
• Failing to keep proof of verification: Always save the verification evidence for audit and compliance.

Using a CRM with integrated communication tools like WhatsApp and SMS CRM and a built-in CRM dialer can help manage follow-ups and keep verification records organised.

Frequently asked questions

How long does it take to verify a business tax number in the UAE? Verification via the FTA online portal is immediate. Once you enter the TRN, you get instant confirmation of its validity and registration details.

Can I verify a tax number without internet access? No. Verification requires access to the FTA’s online system. If you lack internet access, you can contact the FTA helpline for assistance, but online verification is the standard and fastest method.

What should I do if the tax number is invalid? Do not proceed with transactions if the TRN is invalid or inactive. Contact the business for clarification or request a valid TRN. Using invalid TRNs in your VAT filings can cause compliance problems.
