Understanding Time of Supply Under GST: Key Principles and Scenarios
Understanding the Time of Supply in GST
To accurately calculate and fulfill tax obligations, it is crucial to establish the date when the tax liability arises, known as the Time of Supply, as outlined in the Goods and Services Tax (GST) Act. The Act distinguishes between the time of supply for goods and services, with specific provisions for each.
Time of Supply of Goods
The tax obligation for goods arises under the following scenarios:
1. Goods Supplied Under Forward Charge
- Earliest of the following dates:
- Invoice Date: The date the supplier issues the invoice. If no invoice is issued, it will be the last date the supplier is legally required to issue one concerning the supply.
- Payment Receipt Date: The date the supplier receives payment (not applicable for advance payments).
Note: The last date for issuing an invoice is determined as follows:
- Movement of Goods: Before or at the time of removal for delivery to the recipient.
- No Movement of Goods: Before or at the time of delivery or making goods available to the recipient.
Payment receipts are recorded as the earlier of:
- Books of Account: The date when payment is recorded in the entity's accounts.
- Bank Account: The date when payment is credited to the entity’s bank account.
2. Goods Supplied Under Reverse Charge
- Earliest of the following dates:
- Goods Receipt: The date when the recipient receives the goods.
- Payment Record Date: The earlier of the date when payment is entered in the books or when it is debited from the bank account.
- Invoice Date: The date immediately after 30 days from the invoice date or any other legal document serving as an invoice.
If it remains indeterminate, the time of supply is the date the transaction is recorded in the recipient's books of account.
3. Time of Supply for Vouchers
- If the supply is identifiable when the voucher is issued: Date of Issuance of the Voucher.
- If the supply is not identifiable: Date of Redemption of the Voucher.
4. Residuary Provision
If the time of supply cannot be established by prior means, the following applies:
- Return Filing: The due date for filing returns, where periodic returns are required.
- Tax Payment: The date of tax payment in all other circumstances.
5. Time of Supply for Additional Value (Interest, Late Fees)
Time of supply related to increased value due to interest, late fees, or penalties occurs on the date the supplier receives such additional value. For instance, if a supplier receives interest on December 15 for a payment delayed to that month, the time of supply is December 15, and tax must be paid by January 20.
Time of Supply of Services
The tax obligation for services arises under these scenarios:
1. Services Supplied Under Forward Charge
- Earliest of these dates:
- If the invoice is issued on time per section 31(2) of the CGST Act: Invoice Date or Payment Receipt Date, whichever comes first.
- If the invoice is not timely: Completion of Service Date or Payment Receipt Date, whichever comes first.
- Otherwise, it is the date the recipient records the service in their accounts.
Note: The time limit for issuing an invoice under section 31(2) is as follows:
- Standard services: Within 30 days from service delivery (or 45 days for certain institutions).
- For insurers, banking firms, or telecom operators: The invoice should be issued before or when recorded in accounts or by the end of the quarter during which the supply was made.
2. Services Taxable Under Reverse Charge
- Earliest of these dates:
- The earlier of payment recorded in the books or when debited from the bank account.
- The date immediately after 60 days from the invoice date or any equivalent legal document.
Should it not be ascertainable, the time of supply is the date the transaction is recorded in the recipient's accounts.
3. Time of Supply for Vouchers
- If identifiable at voucher issuance: Date of Issuance.
- If not identifiable: Date of Redemption.
4. Residuary Provisions
When time of supply remains indeterminate, apply:
- Return Filing: Due date for return filing for periodic returns.
- Tax Payment: Date of tax payment in other scenarios.
Time of Supply with Change in Tax Rates
When goods or services are supplied before or after a tax rate change, the time of supply is determined by:
If Supplied Before Change in Rate
| Invoice Issued | Payment Received | Time of Supply |
|---|---|---|
| Before change | After change | Date of Invoice |
| After change | After change | Earlier of Date of Invoice / Date of Payment |
| After change | After change | Date of Payment |
If Supplied After Change in Rate
| Invoice Issued | Payment Received | Time of Supply |
|---|---|---|
| Before change | After change | Date of Payment |
| Before change | Before change | Earlier of Date of Invoice / Date of Payment |
| After change | Before change | Date of Invoice |
Date of Receipt of Payment
Typically, this refers to the earlier date when the payment is credited to the bank account or entered into books of accounts. However, in scenarios involving a tax rate change, it refers to the date credited if it occurs after four working days from that change.
