Demystifying Time of Supply for Goods under GST: A Guide for Businesses

Understanding when items are supplied under GST is critical for effective tax filing and compliance. This article digs into the major rules, circumstances, and exceptions to assist businesses in navigating this crucial component of the GST system. 

Why is time of supply important in GST?

The period of supply under GST is therefore an important notion that aids in calculating tax due, obtaining input tax credit, and remaining in compliance with the GST system. It has an impact on many areas of the transaction process, including the collection and payment of GST. In the GST system, determining the time of delivery for items is crucial. It necessitates the following:

1. Input Tax Credit: Claiming the input tax credit, for purchases made has a deadline known as the Input Tax Credit Date. 

2. Return Filing Period: The period within which the transaction must be recorded on GST returns. 

3. Tax Liability: The moment at which the seller becomes obligated to pay GST is required.  

Factors on Which Time of Supply Depends

According to the Goods and Services Tax (GST) Section 13 of the GST Act governs the determination of when goods supplies occur. This provision aims to determine the point in time when the responsibility to pay taxes arises for transactions involving goods. 

1. Invoice Problem: The time of supply is usually the day on which the provider provides the invoice. This applies to all normal registered taxpayers (except composition dealers).

2. Payment reception: If payment is received before the invoice is issued, the time of supply is the date of payment reception. All taxpayers including the composition traders, are also subjected to this requirement.

3. Dispatch of products: Basically, if the selling of the goods is done before the payment and invoice was not generated then the time of supply will conclude the dispatch date of the goods. 

4. If the invoice is not received by the due date, the time of supply is assumed to be the same. Section 31 of the statute requires this information. 

It is critical to ascertain the timing of supply in order to appropriately calculate tax liabilities and guarantee GST compliance. Read the article on Section 13 of the GST Act to learn more

Exceptions and Special Cases

Certain exceptions and unique instances apply to these rules:

1. If an advance payment over 10% of the total value of the supply is received before the issuing of the invoice, the date of supply for the advance amount is the day such payment is received.

2. Imported products: The time of supply for imported products is the date of the clearance from customs. 

3. Consignment Sales: In the case of a consignee sale, the time of supply in consignment sales is the same day on which the goods or services are sold to the third party by the consignee itself. 

Understanding Time of Supply through Examples

Let's look at some examples of how these principles can be applied:

Scenario 1: On January 5, 2024, a composition dealer gets a 50% advance payment for products to be delivered later. On February 10, 2024, the remaining money and invoice are due.

Time of Supply: The time of supply for the advance payment (50%), is January 5, 2024. The remaining amount will be available on February 10, 2024.

Scenario 2: The sequence of events is as follows; On January 10 2024 a supplier sent an invoice. The goods were delivered on December 30 2023. The payment was received on January 15 2024. 

According to the invoice date the time of supply will be considered as January 10 2024.


Time of Supply of Goods is a really important factor especially for large-scale businesses and companies so that they can streamline the workflow of the business while avoiding any errors, dues, or fines. You can confidently manage this key component of GST if you understand the primary requirements, exemptions, and practical examples. Remember that getting expert advice from a knowledgeable tax adviser for complicated circumstances or particular questions is always suggested.
