Goods in Transit: E-Way Bill Validity During GST Rate Change

The e-way bill is an electronic authorisation mandated by the Indian Goods and Services Tax (GST) regime for the inter- or intra-state transit of goods where the consignment value exceeds ₹50,000. The validity period of this document is calculated based on the anticipated distance of the shipment. The governing principle is that an e-way bill generated for a consignment in transit retains its validity for the originally stipulated period, irrespective of a subsequent change in the GST rate. Consequently, there is no requirement to cancel the existing e-way bill and generate a new one solely due to the rate change.

Scenario Analysis: Before, During, and After the Change

Invoice Generated BEFORE the Rate Change Date (e.g., Dec 28, 2023)

• Applicable GST Rate: 18% (the rate prevailing on the invoice date).
• E-Way Bill: Generated showing 18% tax.
• Validity During Transit: The E-Way Bill remains fully valid even if the goods are in transit on or after January 1, 2024. The transporter does not need to generate a new E-Way Bill.
• Reasoning: The transaction is governed by the old rate as the "time of supply" occurred before the change.

Invoice Generated ON or AFTER the Rate Change Date (e.g., Jan 1, 2024)

• Applicable GST Rate: 12% (the new rate effective from that day).
• E-Way Bill: Must be generated showing 12% tax.
• Validity During Transit: The E-Way Bill is valid for its standard duration.

Any goods invoiced after the change must use the new rate and a corresponding E-Way Bill.

GST Rate Change and Goods in Transit

The applicable GST rate for a supply is established by the "time of supply" rules, which use the earliest of the date of supply, invoicing, or payment.

In the event of a GST rate change:

• Tax Liability: For goods where an invoice was issued at the previous GST rate before the change took effect, the tax liability is accounted for at that old rate.
• E-Way Bill Status: The e-way bill, generated based on that invoice, remains legally valid for its original duration. There is no statutory requirement to cancel the existing e-way bill or generate a new one for consignments already in transit when the new rate is implemented.

Key Points on E-Way Bill Validity During GST Rate Change

• No Cancellation Required: Existing E-Way Bills do not need to be cancelled or reissued when GST rates change while goods are in transit. Transporters and suppliers can proceed with delivery as per the originally issued E-Way Bill.
• Original Validity Applies: The validity period indicated on the original E-Way Bill (calculated based on distance to be travelled: typically, 1 day for every 200 km or part thereof) continues to apply, regardless of the GST rate change date.
• Date of Supply for GST Rate: The applicable GST rate is determined based on the "date of supply." If the supply (sale) occurs after the effective date of the new rate, the revised rate applies, even if the goods were sent before the rate change.
• Legal Basis: This practice stems from Rule 138 of the CGST Rules, 2017, and GST Council clarifications confirming that rate changes do not invalidate E-Way Bills issued prior to the change.

Key Considerations and Best Practices

1. What if the E-Way Bill Expires During Transit?

This is a separate issue from the rate change. The validity of an E-Way Bill is based on distance, not tax rates. If the E-Way Bill is about to expire before the journey is completed, the generator (supplier, recipient, or transporter) must extend its validity in the E-Way Bill system before it expires. The rate change itself does not affect this process.

Clarity on Invoice Date vs. Movement Date

Do not confuse the date of movement with the date of invoice. Goods invoiced on December 30th (at 18%) but starting their journey on January 2nd must still be accompanied by an E-Way Bill generated with the 18% rate.

Impact of Reverse Charge Mechanism (RCM)

In cases where tax is payable on a reverse charge basis by the recipient, the "time of supply" is the date of receipt of goods. However, the E-Way Bill is still generated based on the original invoice from the supplier. The applicable rate would be the rate prevailing on the date the supplier issued the invoice.

Best Practices for Businesses

• Clear Communication: Inform your logistics and accounts teams well in advance of any anticipated rate changes.
• Review Invoice Dates: Be meticulous about invoice dates. An invoice dated just one day before the change can lock in the old rate, while an invoice dated on the change day will apply the new rate.
• Audit Trail: Ensure your documentation (invoice, E-Way Bill, delivery challan) is consistent. The tax rate on the invoice must match the rate declared in the E-Way Bill.
• No Need to Cancel/Re-generate: Do not cancel and re-generate E-Way Bills for in-transit goods solely because of a rate change. This is unnecessary and could create confusion.

Conclusion

The validity of an active e-way bill remains intact despite a GST rate revision. The applicable tax rate is determined by the date of invoicing. Consequently, goods invoiced before the change continue transit under the original e-way bill, whereas new invoices require an e-way bill reflecting the new rate.
