Businesses with taxable supplies exceeding OMR 38,500 annually must register for VAT. Voluntary registration is available for businesses above OMR 19,250. Free zone companies operating exclusively in the zone may have specific exemptions.

Oman applies a standard 5% VAT rate, introduced in April 2021. Certain goods and services are zero-rated (exports, some food items) or exempt (financial services, residential rentals). EnterSlice ensures correct VAT treatment for your specific business.

VAT returns must be filed within 30 days of each quarterly period end. Late filing attracts penalties from OMR 500 to OMR 5,000. EnterSlice's proactive calendar management ensures you never miss a deadline.

The standard corporate income tax rate is 15% on taxable profits. Small businesses with turnover below OMR 30,000 may qualify for the small taxpayer regime. Free zone companies operating within the zone enjoy 0% corporate tax during their tax holiday period.

Yes. Input VAT paid on business purchases and expenses is recoverable against output VAT on your sales, subject to the expense being directly related to taxable business activities. EnterSlice optimises your input tax recovery strategy to minimise your net VAT liability.

An OTA audit requires you to provide financial records, VAT returns, and supporting documentation. EnterSlice represents you directly in the audit, prepares all required schedules, and liaises with OTA officers on your behalf to achieve the best possible outcome.
