Value of Supply in Oman VAT

Yarab A | Updated on: May 30, 2022

With VAT in Oman, the supply of taxable goods and services will attract 5% VAT. The responsibility to levy and remit the VAT amount to the authorities is on businesses. While 5% VAT needs to be collected, the question remains: What will be the value on which VAT needs to be levied?

This is crucial because, If goods and services are undervalued, it leads to short tax payments, leading to non-compliance. On the other hand, overvaluation will result in loss of revenue for businesses by way of additional taxes and, ultimately, higher buying costs to customers. 

To avoid the situations mentioned above, specific guidelines are detailed in VAT law that help you determine supply value. Let us understand the value of supply in Oman VAT.

Value of supply in Oman

The value of supply, also called taxable value, can be defined as the total value of the consideration excluding the VAT. The consideration includes all expenses, any fees or taxes due as a result of the supply, charged by the taxable supplier to the customer. Any deductions, subsidies, grants or amounts determined by the regulations are excluded from the value of supply.

In simple words, the supply value will be sale value, including all other expenses such as packing charges, installation fee, etc., but excludes any deduction such as discounts, subsidies, etc.

Value of supply example

A-One Spares Ltd sells spare parts worth Rs 100,000, including packing charges of 500 to Abdul Traders. A-One Spares also provide a discount 250 OMR.

Spare Parts


Packaging Charges




In the above case, the supply value will be the total consideration (before VAT), including additional charges towards packing charges less discount amount. The value of supply will be 100,500 (Spare Parts 100,000 + Packing Charges 750 – Discount 250). The 5% VAT will be calculated on 100,500, i.e. 5025.

Value of supply in case of inclusive of VAT

In the above example, the supply value was exclusive of tax, and it was relatively easier to determine the value. How to determine if the value is inclusive of tax? 

It is pretty simple. You just need to reduce the VAT amount from the total consideration (inclusive value). To do that, use the below formula:

VAT Amount = Total Consideration * 5 (Rate of VAT) / (100 + 5% VAT)

The VAT amount arrived using the formula above should be reduced from the total consideration.

Let’s apply this formula to considering the above example of A-One Spares.

Total consideration, including VAT is 105,525

To arrive at the value of supply, you need to reduce the VAT from 105,525 as calculated below:

105,525 * 5 /105 = 5,025

Now, reduce 5.025 from total consideration to arrive at the taxable value of supply. This will be useful when you receive the invoice from your supplier with inclusive of VAT value.

Given the different nature of supplies such as deemed supply, exports, imports, etc., separate guidelines are prescribed in VAT law and regulations. It’s essential to apply a suitable method to determine the value to avoid any non-compliance arising from it.  One way to eliminate this risk is to use VAT software that automates the calculation.
