Sir,
As per rule 2 of Draft Rules dated 31-3-2017 for GST - Determination of Value of Supply -
"The value of the supply of goods or services or both between distinct persons as specified in sub-section (4) and (5) of section 25 or where the supplier and recipient are related, other than where the supply is made through an agent, shall,-
(a) be the open market value of such supply;
(b) if open market value is not available, be the value of supply of goods or services of like kind and quality;
(c) if value is not determinable under clause (a) or (b), be the value as determined by application of rule 4 or rule 5, in that order:
Provided where the recipient is eligible for full input tax credit, the value declared in the invoice shall be deemed to the open market value of goods or services.
Here necessary clarification is required regarding what is "open market value" and Is it same as transaction value? The rule has clearly stipulated that in case where the receiver is eligible to full input tax credit the value declared in the invoice shall be deemed to be open market value of goods or services.
