VAT Return Filing in the UAE: What Every Business Owner Gets Wrong

Filing your VAT return in the UAE isn’t just a routine accounting task. It’s a compliance responsibility that can make or break your business’s financial health. Despite clear rules from the Federal Tax Authority (FTA), many business owners still get it wrong. Missed deadlines, incorrect entries, and overlooked documentation are all too common, and they come with heavy VAT return penalties in the UAE.

In this blog, we’ll break down the most common mistakes when filing VAT returns in the UAE, explain why they happen, and show you how to avoid them. Whether you’re a first-time filer or an experienced business owner, this guide will help you stay compliant, avoid fines, and streamline your UAE VAT filing process once and for all.

1. Missing VAT Filing Deadlines

One of the most frequent and costly mistakes is missing the VAT return deadline in the UAE. Businesses are required to file VAT returns within 28 days after the end of each tax period. Depending on the nature of your business, your filing frequency could be monthly or quarterly.

However, many businesses forget to account for weekends or public holidays. The FTA portal (now EMARATAX) does not automatically adjust deadlines, meaning even a one-day delay can lead to administrative penalties.

Tip: Always check your filing calendar on EMARATAX and set automated reminders for your tax periods. It’s best to file at least a few days before the due date to avoid last-minute technical or payment issues.

2. Submitting Incomplete or Incorrect VAT Data

When filing your VAT return submission in the UAE, it’s easy to make data entry errors. Mistakes often occur when filling in sales, purchases, imports, exports, or reverse charge sections. Even small inaccuracies can trigger audits or lead to penalties.

For instance, incorrectly reporting total sales (output VAT) or missing expenses (input VAT) skews your payable VAT amount. Overreporting may cause cash flow issues, while underreporting can lead to fines.

Tip: Reconcile your accounting records, invoices, and bank statements before submitting. Review your entries line by line and, if needed, have a VAT specialist review your return before submission.

3. Failure to Retain Proper Invoices and Documentation

The VAT return requirements in the UAE are very specific about documentation. Businesses must maintain all invoices, receipts, import/export declarations, and contracts for at least five years (or 15 years for real estate businesses).

Failure to maintain or present these documents during an FTA audit can result in non-compliance penalties- even if your VAT return was filed correctly.

Tip: Digitally archive all tax invoices, purchase orders, and bank statements. Ensure your invoices comply with FTA standards, showing TRN numbers, correct VAT amounts, and supplier details.

4. Not Reconciling Output and Input VAT

This is one of the biggest operational errors businesses make. Many owners fail to reconcile output VAT (on sales) with input VAT (on purchases).

If your business is paying more VAT on purchases than it’s collecting on sales, you may be eligible for a VAT refund. Conversely, over-claiming input VAT or missing out on output VAT can trigger red flags with the FTA.

Tip: Perform monthly reconciliations before filing. Use accounting software that automatically matches your invoices to ensure accurate VAT reporting.

5. Misunderstanding Tax Periods (Monthly vs Quarterly)

Not all businesses follow the same filing schedule. Some are required to file VAT in the UAE monthly, while others do so quarterly, depending on their annual turnover and registration profile.

Businesses often miss deadlines because they assume they fall into the quarterly cycle, only to realise too late that they are required to file monthly.

Tip: Log in to your EMARATAX dashboard to confirm your assigned tax period. The FTA assigns the tax period during registration, and any change requires formal approval.

6. Incorrect Reporting of Zero-Rated, Exempt, and Out-of-Scope Supplies

Many businesses confuse zero-rated, exempt, and out-of-scope supplies, which drastically affects how VAT is calculated.

• Zero-rated supplies (0%): Exports, international transport, certain educational and healthcare services.
• Exempt supplies: Residential rent, local passenger transport, and financial services.
• Out-of-scope supplies: Transactions that fall completely outside VAT (like salary payments or imports under reverse charge).

Classifying these incorrectly can lead to overstated or understated VAT.

Tip: Understand the category of every transaction type your business handles. Maintain a clear internal guide for your accounting team on VAT classifications.

7. Ignoring VAT on Imports and Reverse Charges

Many businesses incorrectly assume that imports are automatically handled by customs and skip reporting VAT on them. However, under the reverse charge mechanism, the importer (you) must declare and account for VAT on imports within your VAT return.

Failure to do so means your UAE VAT returns process will be incomplete, and your input VAT claims may be rejected.

Tip: Check your customs records and ensure every import entry is reflected in your VAT return under the correct section.

8. Using the Wrong VAT Return Form (VAT 201)

Another common mistake is using incorrect forms. All standard VAT-registered businesses must use Form VAT 201 for their VAT return submission in the UAE. Using outdated or alternate formats can lead to rejection or non-compliance issues.

Tip: Always use the latest version of Form VAT 201 via the EMARATAX portal and double-check all fields before submission.

9. Errors in the FTA Portal (EMARATAX) Submission

Even businesses with accurate records can make mistakes when submitting through the FTA EMARATAX system. Issues like incorrect TRN entry, uploading the wrong documents, or failing to confirm submission can all cause delays.

Tip: Ensure your company TRN is active and verified before submission. Review the “confirmation page” before finalising. Many businesses assume the return was filed when it wasn’t fully submitted.

10. Not Paying VAT Due by the Deadline

Filing your return is only half the job. The payment of the due VAT must also be made before or on the due date. Even if your VAT return is submitted on time, failure to pay the owed VAT will result in immediate fines and late payment penalties.

Tip: Make the payment a few days before the deadline to account for bank processing time. The FTA considers your payment “received” only when it reflects in their system, not when you make the transfer.

11. Ignoring Regular Professional Review or Accounting Checks

One of the biggest reasons for recurring mistakes is the lack of professional oversight. Small and medium businesses often prepare and file VAT returns in-house without professional review. Over time, small inconsistencies can snowball into compliance violations.

Tip: Have your VAT returns reviewed quarterly by a registered tax agent or accounting professional. This ensures compliance, identifies missed claims, and reduces your audit risk significantly.

12. Lack of Understanding of Voluntary Disclosures

If you discover an error after submitting your VAT return, the FTA allows you to file a Voluntary Disclosure (Form 211). However, many businesses are unaware of this or delay the process, which can increase penalties.

Tip: As soon as you spot an error, file a VAT return voluntary disclosure UAE form to correct it. The earlier you act, the lower your fines and compliance risks.
