Taxable Event in GST is known as Time of Supply

Under GST, a uniform and single Taxable Event CALLED ‘supply’ would replace multiple taxable events which are in current Indirect Tax regime, stated as follows :

  • For manufacture, Taxable event is when manufacture is complete – Excise levied.
  • For Service provided, Taxable event is when services provided completely OR agreed to be provided (advance received) – Service Tax levied. Subject to Invoice
  • For sale of goods, Taxable event is when sale of goods is complete – VAT/ CST levied.

Simply under GST the liability to pay tax is called as Time of Supply.

Thus, constant monitoring and compliance required for keeping track of all these different taxable events at present regime would fade away in GST, but, simultaneously, the term ‘supply’ will hold the greatest significance and shall be important in determining the tax ability of all transactions, whether commercial or otherwise under GST regime.

No doubt, GST has made taxable event simpler by keeping it uniform but it is crucial here to note that the term “includes” is attached with the word supply. And there has been lot of judicial pronouncements to establish the meaning of includes in law. – Here we recommend business to take consultations from professionals because supply falling under charging section.

Sharing some judicial judgement for reference:

The cases of Doypack Systems (Pvt) Ltd. Vs. Union of India [1988 (36) ELT 201 (SC)], the Hon’ble Supreme Court has interpreted the meaning of the term ‘includes’, as “It is well settled that the word ‘includes’ is an inclusive definition and expands the meaning.”

Similarly, in the case of Tata Consultancy Services Vs. State of Andhra Pradesh [2004 (178) ELT 22 (S.C.)], the Hon’ble Supreme Court has interpreted the meaning of the word ‘includes’, to suggest that “….When the word ‘includes’ is used in an interpretation clause, it must be construed as understood (comprehending) not only such things as they signify according to their nature and import but also those things which the interpretation clause declares that they shall include.

Keeping in mind, the importance this term supply would entail in GST, the term supply could have been defined in exhaustive manner to ensure the boundaries restricting any sort of wide interpretation of the taxable event. That would have further reduced the scope of litigation’s which is the major challenge with exiting indirect tax regime.

Ironically, the other way round we can conclude that anything defined in GST under Negative or exempted list is not “supply”.

Ease of Business with uniform taxable event

Based on above discussions, it is critical that the lawmakers should wake up to the realities of the situation and ensure to have concrete taxable base by defining the term ‘supply’ in clear and unambiguous manner, which is the pivotal term under the proposed GST regime, that would be the centric point to determine levy & collection of GST.
And to keep the purpose of GST alive by not getting in litigations, whereas to have ease & real growth of business & economy.


The existing regime of taxation identifying taxable event for each activity was challenging  due to non uniformity of same under manufacturing, trading, services, customs etc.  GST has made it uniform for all the events by bringing it under one net of taxable event called as “Time of Supply”.

Though this will be in line with Service Tax Point of Taxation Rules.

Impact of GST in Business Processes across Industries

GST will affect all industries Business Processes, irrespective of the sector. It will impact the entire value chain of operations , namely:-

1. Procurement

Purchasing across states is set to become a lot more hassle free as a unified tax structure will allow for seamless movement across state borders. Currently interstate logistics is a major pain area with a long queue of trucks waiting for clearance by state tax and octroi authorities is a common sight on Indian highways. This will soon be relegated to the past as free movement of goods will be possible within India. It is estimated that this will reduce distribution costs by as much as 10-15% and reduce the time taken for transport at the same time. Along with lesser inventory to be maintained due to shorter transport times, this will also open up a wider base of suppliers that will push costs further down.

2. Manufacturing

 Manufacturing is a very complex industry while reducing the cost of production & improving the incremental value for customers is one of the major challenge for every business. The new GST regime will trigger a transformation shift from a complex multi- layered indirect taxation system to a unified indirect taxation system. Under the new regime reduction in tax cascading may lead to lower cost. Therefore it will compel organizations to re- align bottlenecks in production process to make business opportunities better.

3. Distribution

Under GST the distribution model needs to be revamped due to free flow of tax movement in case of inter state supply of goods . Now businesses will not think of opening warehouses just because of cutting CST cost, instead they will think in more competitive manner & follow benchmark process like Hubs & Spoke Model where warehouse will be opened as a central depot & based on the customer demand delivery of goods shall be made. Avoiding unnecessary blocking of funds.

4. Warehousing

GST presents an opportunity for industry players to consolidate their warehouses and set up larger facilities, which will bring in supply chain efficiency. Therefore Model like Hubs & Spokes Model will be of real sense for logistic companies.

5. Sales

Since GST has made availement of credit arising from inputs a detailed task by following defined steps mentioned in GST. Therefore it automatically leads that tax collected  from sales made to customers should be deposited timely in order to allow them with credit benefits, else loosing on credit benefit is just like standing on edge & loosing the customer in GST regime.      

6. Purchase

 So far businesses with vendors was done even without contracts & agreements as credit benefit was not dependent on payment of tax by the vendor or not. But because in GST one can book the credit benefit only once there supplier has deposited tax. Now to make sure that vendors abide by these rules & let business function smoothly, there should be fixed terms & condition at the beginning which shall be done through agreements.   

We will try to sensitise about GST impact in each of these chains & many other chains.

Stay tuned 🙂


Organizations with heterogeneous transactional system may face the greatest challenge as they will have to make changes in terms of technology across all the systems & ensure everything works together seamlessly post GST implementation.
