Igst and freight

Here is the solution to the query presented in the forum post regarding the IGST implications and potential credit arbitrage between the two delivery options:

Option A: FOR Basis (Delivered Basis)

• GST Treatment: This qualifies as a Composite Supply under Section 2(30) of the CGST Act. The supply of goods and the transportation service are naturally bundled, with the goods acting as the principal supply.

• Tax Liability: As per Section 8 of the CGST Act, the entire value of ₹1,00,000 will be taxed at the GST rate applicable to the principal goods.

• IGST & Credit: Since it is an interstate transaction (West Bengal to Kerala), the supplier will charge IGST on the full invoice value. The Kerala unit can claim the entire IGST as Input Tax Credit (ITC), assuming standard eligibility rules are met.

Option B: Ex-Works (ExW) Basis + Freight Extra

The tax treatment depends on who arranges and bills the freight:

• Scenario 1: Supplier includes freight in the same invoice: If the supplier provides the delivery but lists the ₹5,000 freight separately on the invoice, it gets added to the transaction value under Section 15(2)(c) of the CGST Act. It will still attract the same IGST rate as the goods.

• Scenario 2: Buyer pays the transporter directly: If the Kerala unit contracts a Goods Transport Agency (GTA) independently:

  • The service is treated as a separate supply of transport services.

  • The Kerala unit will pay GST either under the Forward Charge Mechanism (FCM) to the transporter or under the Reverse Charge Mechanism (RCM) at 5% IGST (since the destination/place of supply is Kerala).

  • The Kerala unit can claim full ITC on both the goods invoice (from the supplier) and the freight invoice (FCM/RCM).

Is there any IGST Credit Arbitrage?

Practically, No.

Since the Kerala unit is fully eligible to claim Input Tax Credit (ITC) on both the goods and the freight under either option, there is no permanent credit loss or arbitrage advantage.

However, a cash flow variation can happen depending on the tax rates:

• If the goods have a high GST rate (e.g., 28%), Option B might be marginally better for immediate cash outflow because the freight portion (₹5,000) will only attract 5% or 12% GST instead of 28%.

• If the goods attract a lower rate (e.g., 5% or exempt), Option A keeps the freight tax incidence aligned with that lower or exempt rate.

Summary

Option A (FOR) treats goods and freight as a single Composite Supply, taxing the entire amount at the rate of the goods. Option B (ExW) separates the two, taxing the freight under GTA service rules (often 5% under RCM). Because full Input Tax Credit (ITC) is available to the recipient under both methods, no permanent credit arbitrage exists, though slight cash flow differences may occur depending on the specific GST rate of the goods.
