Valuation of goods and services is a crucial aspect of Goods and Services Tax (GST) compliance in India. The value of taxable supplies determines the amount of GST liability for a taxpayer. The valuation of GST is governed by specific rules and guidelines provided under the GST law. Here’s an overview of the valuation principles for GST:

1. Transaction Value:
   • The transaction value is the primary basis for determining the value of taxable supplies under GST.
   • Transaction value is the price actually paid or payable for the supply of goods or services when the supplier and the recipient are not related and the price is the sole consideration for the supply.
   • It includes all costs, charges, expenses, duties, and taxes except GST itself and discounts allowed before or at the time of the supply.
2. Open Market Value:
   • If the transaction value is not ascertainable (e.g., there is no consideration or the consideration is not solely in money), the open market value of the supply is used for valuation.
   • Open market value refers to the value of goods or services that they would fetch if sold in the open market at the time of supply.
3. Value of Supply of Goods or Services between Related Persons:
   • If the supplier and the recipient are related persons, and the relationship influences the price, the value of supply is determined based on the open market value.
   • If the open market value is not available, the value is determined using the value of similar supplies made under similar circumstances.
4. Value of Supply of Goods and Services in Special Cases:
   • Specific rules govern the valuation of certain types of supplies, such as:
     • Deemed value for supplies without consideration (e.g., gifts, samples).
     • Composite or mixed supplies (supply of goods and services together).
     • Residual method for determining the value of supplies for which specific valuation rules are not provided.
5. Taxable Value for Taxable Goods or Services:
   • The taxable value of goods or services is the value on which GST is levied. It is determined by subtracting any discounts or incentives provided by the supplier from the transaction value.
6. Adjustments:
   • Adjustments may be required in certain cases, such as:
     • Additional consideration after the supply.
     • Reduction in value due to returned goods or services.
     • Increase or decrease in the value of supply due to subsequent events impacting the transaction value.

It’s important for businesses to accurately determine the value of taxable supplies in accordance with the valuation rules prescribed under the GST law to ensure compliance and avoid penalties. Additionally, proper documentation and record-keeping of transactions are essential to support the valuation of supplies and facilitate GST audits and assessments.
