Income Tax Registration and Tax Card Support in Oman
Businesses operating in Oman generally need to register with the Oman Tax Authority and maintain an active tax file.
The OTA registration guidance states that income tax registration is mandatory for establishments engaged in economic activity in Oman within a period not exceeding 60 days from the date of activity commencement or registration with the Ministry of Commerce, Industry and Investment Promotion.
We help with:
- OTA portal registration guidance
- Tax file setup
- Tax card support

- Activity and taxpayer details review
- Document preparation
- Authority follow-up where required
- Updating tax registration details if company records change
A tax card may be needed for banking, government transactions, labour-related processes, and business compliance.

If your company is still under formation, visit our company registration in Oman or LLC company registration in Oman service pages.
Corporate Tax Return Filing in Oman
Oman applies corporate tax to companies and establishments based on taxable income and applicable tax rules.
The standard corporate tax rate is 15% of net taxable income. Some qualifying small enterprises may be eligible for a 3% rate if they meet OTA conditions, including limits related to CR capital, annual gross income, number of workers, and activity type.
We help companies prepare and file corporate tax returns by reviewing:
- Trial balance
- Financial statements
- Profit and loss report
- Balance sheet
- Bank statements
- Sales invoices
- Purchase invoices
- Expense records
- Depreciation schedules
- Payroll and staff cost records
- Related-party transactions
- Tax adjustments
- Prior year filings
The OTA portal and income tax FAQs should be checked before filing because return deadlines depend on the taxpayer category and accounting period. OTA FAQs refer to 15% taxpayers submitting returns before the expiry of 4 months from the end of the tax year, while 3% taxpayers submit before 3 months.

VAT Registration and VAT Return Filing in Oman
VAT is charged at 5% on most taxable goods and services in Oman. Businesses must monitor taxable supplies and register for VAT when they meet the mandatory threshold.
VAT registration is generally required when annual taxable supplies reach or are expected to reach OMR 38,500. Voluntary registration may be available from OMR 19,250. Gov.om also notes that for non-resident companies, there is no revenue limit for VAT registration.
MakeMyCompany supports:
- VAT eligibility review

VAT compliance depends heavily on clean bookkeeping. Your sales invoices, purchase invoices, credit notes, debit notes, bank records, and accounting entries should match the VAT return.

- Correct VAT rate usage
- Zero-rated and exempt treatment checks

Excise Tax Support in Oman
Excise tax applies to selected goods considered harmful to health or society. OTA excise guidance refers to goods such as tobacco and its derivatives, energy drinks, soft and sweetened drinks, alcoholic beverages, pork and its products, and other excisable categories.
Businesses dealing with excisable goods may need registration, classification, return filing, and record maintenance.
MakeMyCompany can assist with:
- Excise registration review
- Excisable product classification
- Product category review
- Rate guidance
- Excise return support
- Import and distribution record review
- OTA clarification support

Withholding Tax and Cross-Border Payment Guidance
Some payments to non-resident persons or companies may trigger withholding tax obligations in Oman. OTA tax rate guidance refers to 10% withholding tax on payments made to non-residents for services, interest, or royalties.
Withholding tax should be reviewed before making cross-border payments because treaty relief, documentation, and payment classification may affect the position.
We help review:
- Payments to foreign service providers
- Royalty payments
- Interest payments
- Consultancy and management fees
- Contract wording
- Tax residency certificate needs
- Double tax treaty considerations
- Filing and payment deadline guidance

Oman issued Personal Income Tax Law through Royal Decree 56/2025. OTA guidance states that the law will enter into force at the beginning of 2028, with an exemption threshold of OMR 42,000 and a 5% rate.
This does not replace current business tax compliance, but employers, high-income individuals, and business owners should track implementation updates and executive regulations.
MakeMyCompany can support early planning for:
- Employer readiness
- Payroll data review
- Compensation structuring discussion
- Expatriate planning
