Filing VAT returns in the UAE is straightforward when processes are in place, but simple mistakes can trigger fines, voluntary disclosures, and lengthy audits. Below are the six most common errors businesses make on their VAT returns, why they matter, and practical steps to avoid them.
Mistake 1: Classifying Sales by Customer Location Instead of Fixed Establishment
Sales must be classified based on your business’s fixed establishment, not where the customer is located. Misclassifying sales by customer location can lead to incorrect emirate reporting and mismatches during FTA checks.
How to fix it:
- Confirm your fixed establishment address used for VAT registration and ensure all sales are recorded against that establishment.
- Update invoicing and accounting systems to use the fixed establishment for emirate reporting.
- Document any multi-establishment operations clearly so each sale is mapped to the correct establishment.
Mistake 2: Not Reporting Zero-Rated and Exempt Sales
Zero-rated and exempt supplies have no VAT charge, but they still must be declared in the return. Omitting these sales creates an incomplete filing and increases the likelihood of an FTA query or penalty.
How to fix it:
- Identify and separate zero-rated and exempt transactions from standard taxable sales.
- Record them clearly in your return and keep supporting documentation to show why each sale qualifies as zero-rated or exempt.
Mistake 3: Submitting Returns Without an Invoice-Wise Working
FTA auditors often request detailed invoice-level backup and typically allow only a short response window. Preparing invoice-wise workings in advance saves time and reduces the risk of errors.
What to include in your invoice-wise working:
- Invoice number and date
- Customer name and location
- Taxable value and VAT amount
- Classification (taxable, zero-rated, exempt)
- Any cross-references to accounting entries
Mistake 4: Claiming VAT on Non-Recoverable Expenses
Not all VAT paid on purchases can be reclaimed. Claiming VAT on expenses that are non-recoverable exposes the business to adjustments and penalties.
How to fix it:
- Review FTA guidance to identify blocked or non-recoverable expenses applicable to your business.
- Keep clear supporting documentation proving the business use and recoverability of input VAT.
- Implement an internal policy and approval workflow for reclaiming input VAT.
Mistake 5: Failing to Account for the Reverse Charge Mechanism (RCM) on Imports
If you import goods or services subject to RCM, you must account for output VAT and — where applicable — reclaim it as input VAT. Even if there is no net VAT payable, these transactions must be disclosed in the return.
Practical notes:
- Record the output VAT on import under the appropriate return rows (for example, output VAT for imports may be reported in rows 3, 6, or 7 depending on the transaction).
- Claim the corresponding input VAT back where permitted (often in row 10).
- Maintain clear import documentation and ensure the reverse charge entries are supported by purchase invoices and customs documentation.
Mistake 6: Missing the Filing and Payment Deadlines
Late filing or late payment leads to significant penalties and can force the business into voluntary disclosure procedures, which add time and cost.
How to fix it:
Reconcile VAT figures before submission to avoid last-minute corrections.
Set calendar reminders well ahead of the due date and assign responsibility to a specific person.
Automate checks where possible or outsource VAT filing if you lack in-house resources.
