Since the UAE introduced Value Added Tax (VAT) in 2018, businesses have been required to comply with a new set of tax regulations to avoid penalties and legal trouble. However, many companies — especially startups and SMEs — they setup company in uae still make common VAT mistakes that can lead to hefty fines and reputational damage. In this guide, we’ll highlight the most frequent VAT errors businesses in the UAE make and share practical tips on how to avoid VAT Mistakes.
Late VAT Registration
The Mistake:
Many businesses underestimate when they should register for VAT. If your taxable supplies and imports exceed AED 375,000 annually, registration is mandatory. Missing this deadline can result in fines starting from AED 10,000.
How to Avoid:
Monitor your revenue regularly. Register for VAT as soon as you cross the threshold — don’t wait until the deadline. Consider voluntary registration if your turnover is above AED 187,500 to build credibility with partners and clients.
Errors in VAT Returns
The Mistake:
Submitting incorrect VAT returns is a common error — businesses often misclassify zero-rated, exempt, and standard-rated supplies or make calculation mistakes.
How to Avoid:
Keep accurate records and reconcile sales, purchases, and expenses every month. Use reliable accounting software or engage a tax consultant to review your VAT returns before filing.
Failing to Issue Valid Tax Invoices
The Mistake:
Some companies issue invoices without including mandatory VAT details, like TRN (Tax Registration Number), supply date, or VAT amount. This can cause compliance issues.
How to Avoid:
Ensure every invoice meets Federal Tax Authority (FTA) standards:
- Seller’s name, address, and TRN
- Invoice number and date
- Customer’s details
- Description of goods/services
- Amount excluding VAT, VAT rate, and VAT amount
Not Filing VAT Returns on Time
The Mistake:
Missing the deadline for filing VAT returns or late payment of VAT liabilities can attract fines starting from AED 1,000 for the first offence, and more for repeated delays.
How to Avoid:
Mark filing deadlines clearly in your calendar. Assign responsibility to a dedicated accountant or tax consultant to prepare and submit returns well before the due date.
Claiming Ineligible Input VAT
The Mistake:
Businesses sometimes reclaim VAT on non-recoverable expenses such as personal spending, entertainment, or passenger cars not used exclusively for business.
How to Avoid:
Understand which input VAT is recoverable and which is not. Keep supporting documents and receipts for every claim and cross-check them against FTA guidelines.
Poor Record Keeping
The Mistake:
VAT laws in the UAE require you to maintain proper books and records for at least five years. Inadequate record-keeping can cause audit issues and penalties.
How to Avoid:
Implement a robust record management system. Store invoices, receipts, contracts, and bank statements securely — and ensure they’re easily retrievable for FTA inspections.
