The Central Board of Indirect Taxes and Customs (CBIC) has issued a fresh instruction to clarify the principles for determining the taxable value of supplies under GST. This guidance comes in response to frequent disputes and varying interpretations among taxpayers and field officers, especially in cases involving discounts, reimbursements, and composite or mixed supplies. The aim is to ensure uniformity in assessment and reduce litigation.

As per the instruction, the taxable value must be based on the transaction value, which is the price paid or payable for the supply, provided the supplier and recipient are not related, and the price is the sole consideration. The CBIC has reiterated that incidental expenses, such as packaging, commission, and freight charged by the supplier, must be included in the taxable value if they are part of the contract. Additionally, any amount the recipient is liable to pay on behalf of the supplier in connection with the supply is also includible in the taxable base.

The instruction further clarifies that post-supply discounts are not deductible unless they are established in advance through a contract and linked to specific invoices. It also emphasizes that in cases of composite supplies, the principal supply shall determine the applicable rate and value. For mixed supplies, the highest rate among the bundled items will apply. These clarifications are expected to promote consistency in valuation practices, support better audit outcomes, and enhance predictability and compliance across the GST framework.
