VAT has been part of the UAE business landscape since 2018, yet many companies continue to make costly mistakes that lead to penalties, cash flow issues, and FTA audits. Even well established SMEs still struggle with record keeping, tax code classification, and documentation accuracy.
With stricter enforcement under UAE VAT Law and Corporate Tax now requiring even more accurate financial reporting, VAT compliance is no longer something businesses can afford to overlook.
Here are the most common VAT mistakes and what your business can do to avoid them.
1. Incorrect classification of zero rated, exempt, and standard rated supplies
Many businesses still confuse zero rated supplies with exempt supplies. Although both categories do not charge VAT to customers, the input VAT treatment is entirely different. Zero rated supplies allow businesses to recover input VAT. Exempt supplies do not allow input VAT recovery.
Incorrect classification affects refund eligibility, profit margins, and compliance accuracy.
How to avoid it:
Maintain a clear list of your product or service categories, review the FTA VAT Law definitions, and ensure your accounting system reflects the correct tax codes.
2. Claiming input VAT without proper documentation
The FTA requires businesses to maintain valid tax invoices for all input VAT claims. Many companies still claim VAT from handwritten notes, incomplete invoices, or non VAT compliant receipts. This is one of the most common reasons VAT refunds are rejected.
How to avoid it:
Ensure every purchase has a proper invoice with TRN, date, tax amount, supplier details, and VAT breakdown. Store documents for at least five years.
3. Errors in reverse charge mechanism for imports
Businesses importing goods or services often misapply the reverse charge mechanism. Either the VAT is not accounted for at all, or it is posted incorrectly in the accounting system.
This results in inaccurate VAT payable or recoverable accounts.
How to avoid it:
Identify all import transactions, apply reverse charge rules correctly, and maintain customs documentation and contracts aligned with FTA expectations.
4. Delayed or incomplete reconciliations before filing VAT returns
Many SMEs file VAT returns based on unverified numbers. Without monthly reconciliation of sales, purchases, and bank accounts, VAT filings can easily become inaccurate.
This leads to FTA queries, penalties, or forced reassessments.
How to avoid it:
Close your books every month, reconcile bank and supplier balances, verify customer ledgers, and ensure all tax codes are correct before filing.
5. Ignoring VAT on non routine transactions
Companies often forget to apply VAT on transactions such as:
- Donations
- Free samples
- Intercompany services
- Asset transfers
- Employee related expenses
- Advance payments
These create gaps between actual business activity and VAT reporting.
How to avoid it:
Review all non regular transactions each month, document their purpose, and follow FTA guidelines for VAT treatment.
