Filing VAT Return for Quarter 1 – 2026 in Oman: Key Guidelines for Businesses

As the Sultanate of Oman continues to strengthen its tax compliance framework, businesses registered for Value Added Tax (VAT) must ensure timely and accurate filing of their VAT returns. The VAT Return for Quarter 1 (January to March 2026) is a crucial compliance requirement, and companies should take proactive steps to meet their obligations with the Oman Tax Authority.

VAT Filing Obligations in Oman

All VAT-registered businesses in Oman are required to file periodic VAT returns based on their assigned tax period—typically quarterly for most small and medium-sized enterprises. The Q1 2026 VAT return covers transactions from 1 January 2026 to 31 March 2026.

The VAT return must include:

• Total taxable supplies (standard-rated and zero-rated)
• Exempt supplies
• Input VAT on purchases and expenses
• Net VAT payable or refundable

Accurate reporting is essential to avoid penalties and ensure compliance with Oman’s VAT regulations.

Important Deadline for Q1 2026

Businesses must submit their VAT returns *on or before 30 April 2026*. Along with filing, any VAT liability must also be paid within the same deadline.

Late filing or payment may result in:

• Administrative penalties
• Interest on outstanding tax
• Increased audit risk

Key Compliance Considerations

To ensure a smooth VAT filing process, businesses should focus on the following:

1. Accurate Record Keeping Maintain proper documentation for all sales and purchases, including tax invoices, debit/credit notes, and import/export records.

2. Input VAT Recovery Ensure that input VAT claims are valid, supported by proper documentation, and relate to eligible business expenses.

3. Reconciliation of Accounts Reconcile VAT figures with accounting records to avoid discrepancies during submission.

4. Correct VAT Treatment Apply the correct VAT rates (5% standard rate or zero/exempt categories) to transactions.

5. Digital Compliance Ensure VAT returns are filed through the Oman Tax Authority’s online portal in the prescribed format.

• Errors in VAT calculations
