How to register for VAT in Oman

Oman implemented Value Added Tax (VAT) at a basic rate of 5% starting April 2021. This brought the country in line with the Gulf Cooperation Council (GCC) VAT framework. Since then, all qualifying businesses based in Oman are obligated to register for VAT and comply with the appropriate filing and invoicing requirements. Whether a local entrepreneur or a foreign business operating in Oman, grasping the steps for registration is essential in avoiding fines and ensuring smooth operations.

About VAT in Oman

Value Added Tax (VAT) in Oman commenced in April 2021 as part of the GCC oil member states effort in attempting to supplement financial revenue and cut back on oil dependence. Oman management implemented a flat 5% VAT on almost all goods and services within the Sultanate. Oman VAT system guarantees a stable and open tax system while raising government revenue to spend on the infrastructure and public services. Moreover, taxes collected can be reinvested back for the economic development of the country. Oman businesses are expected to know their registration obligations as well as their return filing obligations in order to avoid incurring heavy fines and maintain confidence in the trading system.

1. Who Needs to Register for VAT in Oman?

Resident Businesses

1. Mandatory Registration becomes necessary should your taxable turnover exceed OMR 38,500 in the past 12 months or is projected to exceed that in the coming year.

2. Voluntary Registration is available if your turnover is at OMR 19,250, irrespective of not having met the mandatory threshold.

Non‑Resident Businesses

For non-residents doing taxable business in Oman, registration is compulsory from the start date of business activities. In this scenario, either a local representative (Responsible Person) needs to be designated, or a bank guarantee must be submitted to the tax authority.

VAT Registration Timeline (Phased Approach)

As per Decision No. 3/2021 issued by Oman’s Tax Authority, the phased registration timeline is as follows. Though the transitional period is now closed, it is helpful to know how registration for VAT was implemented:

Phase	Annual Taxable Turnover (OMR)	Registration Window	Effective VAT Start Date
1	1,000,000	1 Feb 2021 – 15 Mar 2021	16 Apr 2021
2	500,000–1,000,000	1 Apr 2021 – 31 May 2021	1 Jul 2021
3	250,000–499,999	1 Jul 2021 – 31 Aug 2021	1 Oct 2021
4	38,500–249,999	1 Dec 2021 – 28 Feb 2022	1 Apr 2022

2. When Should You Register?

Oman enforced VAT registration in tiers, segmented by turnover limits. While the transitional periods have lapsed, companies continue to need to determine VAT registration liability continually. Use the look-ahead or look-back method to determine your turnover, whereby both methods are evaluated over 12 months.

3. Documents Required for VAT Registration

To register for VAT, you’ll need the following:

1. Commercial Registration Number (CRN).

2. Legal entity name and trade name.

3. Business activity details and tax year.

4. Owner/Partner ID or passport copy.

5. Contact number and business address.

6. Bank account details.

7. Customs or fiscal number (if applicable).

8. For non-residents: details of the local responsible person or bank guarantee.

4. How to Register for VAT in Oman (Online Portal Steps)

5. After Registration: What You Must Do

As soon as you register, you fall under VAT compliance requirements, like:

1. Issuing tax invoices which need to have VATIN, date of supply, customer’s name, taxable value, and tax amount remitted value.

2. Submission of VAT returns every three months. All returns have to be filed 30 days after the taxable period.

3. Paying the tax remitted to avoid incurring penalties.

Standard-rated (5%): Applies to general goods and services.

Zero-rated (0%): Covers exports, essential food, education, medicine, and international transport.

7. Penalties for Non-Compliance

Not registering on time or providing inaccurate information may attract penalties such as:

1. A fine of anywhere between OMR 1,000 to 20,000.

2. Possible imprisonment for 2 months to 3 years.

3. Double the penalties for repeated offences.

VAT Registration Checklist

To ensure the registration process goes as smoothly as possible, follow this checklist:

Why VAT Compliance is Essential

Following VAT regulations isn't only for staying legally compliant; it's important for the company as well. VAT compliance strengthens credibility with suppliers and customers.

Be it a startup, SME, or even a global company, proper VAT registration and compliance prevent financial losses and reputational harm.
