Dear Jatin-sir,
Your question involves two parts:
-
Whether deducting discount and freight charges from the basic value before applying GST is correct, and
-
Who is liable for RCM (Reverse Charge Mechanism) on freight charges when goods are sent on a "to-pay" basis.
✅ Part 1: Deducting Discount and Freight from Basic Value Before GST
Discount:
-
Under Section 15 of the CGST Act, discounts that are:
-
Given before or at the time of supply, and
-
Recorded in the invoice,
are allowed as deduction from the value of supply.
-
So, the 5% discount shown in the invoice is correctly deducted before calculating GST.
Freight Charges (Deducted from Seller’s Invoice):
✅ So, discount deduction is correct.
❌ Freight deduction from basic value is not correct unless the seller is paying the freight and offering it as a reduction — which is not the case here as the buyer pays it directly to the transporter.
✅ Part 2: Who is Liable for RCM on Freight (GTA) Charges
Reverse Charge Mechanism (RCM) applies to freight under GTA (Goods Transport Agency) under the following:
In your example:
-
The goods are sent on a "to-pay" basis.
-
The recipient (buyer) pays the freight directly to the transporter.
-
If the recipient is a registered person, they are liable under RCM to pay GST @ 5% (without ITC) or 12% (with ITC) on the freight amount.
✅ Recipient is liable for RCM, not the supplier, since they are the one paying the freight directly to the transporter.
