Since VAT was introduced in Oman, businesses must remain compliant with the regulations. However, even well-intentioned companies often make critical VAT filing mistakes that can trigger serious penalties from the Oman Tax Authority. Let’s dive into the most common issues and how to avoid them.

1. ❌ Incorrect VAT Return Calculations

Issue: Many businesses in Oman miscalculate their VAT obligations due to confusion over exempt vs. zero-rated supplies. This is one of the most frequent VAT filing mistakes we see at The Certified Point.

Common Errors Include:

• Misclassifying exempt goods as zero-rated
• Failing to apply VAT on eligible services
• Incorrect Input VAT claims

These errors may result in penalties of over OMR 500 or trigger an audit.

Tip: Use verified tax software or hire a tax consultancy in Oman to review your VAT returns before submission.

2. 📅 Missing the VAT Return Filing Deadline

Missing deadlines is a classic vat filing mistake in Oman. Businesses are required to file monthly or quarterly based on revenue.

Penalties include:

• OMR 100 to OMR 5,000 for late filings
• OMR 50 per day for repeated delays

Tip: Use reminders and assign a registered tax advisor in Oman to ensure timely filings.

3. 🧾 Claiming Ineligible Input VAT

Not all expenses qualify for VAT refunds. A common vat filing mistake in Oman is trying to claim input VAT on personal or ineligible expenses.

Examples:

• Fuel for personal vehicles
• Staff entertainment
• Non-business purchases

Incorrect claims can trigger audits or adjustment notices from the Oman Tax Authority.

Tip: Keep all receipts organized and validated by a professional tax consultancy in Oman.

4. 🔄 Failure to Update Tax Registration Info

Another overlooked vat filing mistake is failing to update your business registration info with the OTA.

You must update:

• Business address or trade license changes
• Revenue changes impacting VAT filing frequency
• New branches or structural changes

Tip: Review your OTA account twice a year and consult a local advisor to avoid compliance issues.

5. 📤 Incorrect VAT Documentation & Record-Keeping

In Oman, businesses are legally required to maintain VAT records for at least 10 years. Poor documentation is a critical vat filing mistake.

Required records:

• Invoices and credit notes
• Import/export records
• VAT return filings

Tip: Consider digitizing your records and conducting annual document audits with certified accountants in Oman.
