GST Valuation of Supplies

Goods and Service Tax (GST) applies to the value of the supply of goods and services provided to the customer by the supplier. GST is charged on the taxable value of supply at each stage of supply and input tax credit is provided for B2B purchases to avoid the cascading effect of the tax. In this article, we look at the valuation of supplies under GST in detail.

GST Valuation Rules for Valuation of Supplies

For valuation of goods and supplies, there are two major rules specified under GST as follows:

  • General Valuation Rules
  • Special Valuation Rules

General Valuation Rules for Valuation of Supplies

General valuation rules are applicable when the supply of goods or services will be made for payment completely in money or cash. In such transactions, consideration or payment will be equivalent to the value of supply.

Consideration = Value of Supply + GST

For example, if a product is sold for Rs.18000 and it attracts 18% GST, then the consideration would be Rs.1,18,000, the value of supply would be Rs.1,00,000 and GST would be Rs.18,000.

Special Valuation Rules

Special valuation rules shall apply when the consideration received seldom involves money or not fully received in money. In such cases, the value of supply shall act as the fair value of the consideration provided less GST applicable.

Consideration = Fair market value of consideration provided - GST applicable

For example, if a supplier sells the product for Rs.1,00,000 and it attracts 18% GST rate if the buyer provides a parcel of land with a fair market value of Rs.1,00,000, then the seller should mandatorily remit the GST as if the consideration provided included GST. Hence, in this case, the buyer should remit the GST of Rs.15254.24 and the value of supply shall reflect Rs.84745.76.

Value of Supply = Fair Value of Consideration Received / (1 + GST Rate Applicable)

Value of Supply = 1,00,000 / (1.18) = 84745.76

When Part of the Consideration is Received in Money

In a transaction wherein part of the consideration the concerned individual receives in money, the total consideration of the sum of money received and the fair market value of the consideration received.

Meaning of Consideration

While calculating the value of supply, consideration received shall act as an important element. Under GST,

anything obtained on the reciprocal basis for the supply of goods or services or jointly can be defined as consideration. Hence, consideration can be money, payment through credit card, payment in kind, bank transfer, cheque, demand draft or any other type of transfer of value.

Frequently Asked Questions

Common questions about GST Valuation of Supplies: Rules, Consideration, Examples.

GST valuation of supplies is crucial because it determines the taxable value on which GST is calculated. The valuation rules ensure that the appropriate amount of GST is levied on the supply of goods and services, preventing any under or over-taxation.
The two main rules for GST valuation of supplies are the General Valuation Rules and the Special Valuation Rules. General Valuation Rules apply when the consideration is entirely in money, while Special Valuation Rules apply when the consideration is not fully received in money.
The General Valuation Rules apply when the supply of goods or services is made for payment completely in money or cash. In such transactions, the consideration or payment will be equivalent to the value of supply plus the applicable GST.
Under GST, anything obtained on a reciprocal basis for the supply of goods or services or jointly can be defined as consideration. This includes money, payment through credit card, payment in kind, bank transfer, cheque, demand draft, or any other type of transfer of value.
When part of the consideration is received in money, the total consideration is the sum of the money received and the fair market value of the consideration received in kind. The value of supply is then calculated based on the total consideration.
Calculating the correct value of supply under GST is important because it ensures that the appropriate amount of GST is levied on the transaction. Undervaluing the supply can lead to under-payment of GST, while overvaluing can result in over-payment, affecting the business's financial position.
The purpose of providing input tax credit for B2B purchases under GST is to avoid the cascading effect of the tax. By allowing businesses to claim credit for the GST paid on their inputs, the tax is effectively levied only on the value added at each stage of the supply chain.
The fair market value of consideration plays a crucial role in GST valuation, especially when the consideration is not fully received in money. In such cases, the fair market value of the consideration received is used to determine the value of supply for GST calculation purposes.
Incorrect GST valuation of supplies can lead to several consequences, including under or over-payment of GST, potential penalties and interest charges from tax authorities, and compliance issues. It can also impact the business's financial position and profitability.
