I am confused about the tax terminology like exempt, nil rated, no tax etc. What do these mean and how does it impact my GST return filing?

Here is a brief explanation of the terms of exempt, nil rated and no tax supplied and how they impact your GST return filing:
 1. Exempt supplies: These are the supplies of goods and/or services that are not taxable under GST, either because they are not covered by the GST law or because they are specifically exempted by a notification. Examples of exempt supplies are agricultural products, education services, health services, etc. If you make only exempt supplies, you do not have to register for GST or file any GST returns. However, if you make both exempt and taxable supplies, you have to register for GST and file GST returns, but you do not have to pay any GST on the exempt supplies. You also cannot claim any input tax credit on the inputs used for making exempt supplies.
 2. Nil rated supplies: These are the supplies of goods and/or services that are taxable under GST, but attract a zero percent tax rate. Examples of nil rated supplies are fresh fruits, vegetables, milk, bread, etc. If you make only nil rated supplies, you do not have to pay any GST on them, but you still have to register for GST and file GST returns. You can also claim input tax credit on the inputs used for making nil rated supplies.
 3. No tax supplies: These are the supplies of goods and/or services that are neither taxable nor exempt under GST. They are outside the purview of GST law. Examples of no tax supplies are alcohol for human consumption, petroleum products, electricity, etc. If you make only no tax supplies, you do not have to register for GST or file any GST returns. You also do not have to pay any GST on them or claim any input tax credit on the inputs used for making them.
