Refund under gst

Yes the refund process is possible in GST. If you find the GST liability is less than the amount you paid, you can claim for a GST refund. You can claim for a GST refund process online. 
The limited time to claim GST is 2 years, means if you find out that you have paid an excessive GST amount rather than required, you will need out to claim it within 2 years. However, remember the claim date relevancy differs on situation. You can claim a GST refund in case of following scenerios:

1- You have submitted excess GST amount due to error in calculation. 
2- If any embassy had made a purchase, it can raise a GST claim
3- An embassy can raise for GST refund on inward supply (inward supply includes both, goods or services supply) 
4- You can also file a GST provisional tax refund (on the basis of a preliminary assessment). This tax refund will be paid in monthly instalment. 
5- The refund will be applicable on goods purchased by international tourists.
6- All kind of dealer export including deemed exports (those transactions in which the payment will be received either in Indian Rupees or in foreign exchange and also supplied goods will not leave the country)

Besides these points there are other more scenarios in which you may claim a GST. You may read all about GST and its refund policies here. 

Refund Application Process Under GST

The refund application has to be made in Form RFD-01 (to be certified by a Chartered Accountant) within a period of 2 years from the relevant date.” This relevant date is different for different scenarios.

1. When the goods are exported through air or sea, then relevant date shall be the date on which such ship or aircraft leaves India.
2. When the goods are carried by a land vehicle, then relevant date shall be the date when the goods cross the land frontier of the country
3. When goods are sent through post, then relevant date shall be the date of despatch of goods from the Post Office.
4. When the supply includes services, and when the same is completed before receipt of payment, then relevant date shall be the payment receipt date.

Once the application made, an acknowledgement in Form RFD-02 will be auto-generated for future references and sent across through an email and an SMS. In case the system finds some deficiencies in the refund application, then Form RFD-03 shall be sent to the taxpayer to correct his application.
