These four categories are often confused. They have different legal definitions and very different input tax credit consequences. Getting the classification wrong can lead to loss of ITC, refund errors and tax demands.
Definitions
Exempt Supply
Section 2(47) defines exempt supply as supply of any goods or services or both which attracts nil rate of tax or which is wholly exempt from tax under Section 11 of the CGST Act or Section 6 of the IGST Act. It also includes non-taxable supply.
Thus, exempt supply is a broad category that includes:
- Nil-rated supplies
- Wholly exempt supplies under exemption notifications
- Non-taxable supplies
Nil-Rated Supply
A nil-rated supply is one on which the GST rate is 0% by a rate notification. The goods or services are within GST but taxed at nil rate. Example: fresh fruits, vegetables, unbranded cereals, certain health and education services.
Zero-Rated Supply
Section 16(1) of the IGST Act defines zero-rated supply as:
- Export of goods or services or both
- Supply of goods or services or both to a Special Economic Zone (SEZ) unit or SEZ developer
Zero-rated does not mean exempt. It means the supply is taxable, but the output tax rate is effectively zero, and input tax credit is fully available.
Non-Taxable Supply
Section 2(78) defines non-taxable supply as a supply of goods or services or both which is not leviable to tax under the CGST Act or IGST Act. Examples:
- Alcohol for human consumption
- Petroleum crude, high speed diesel, motor spirit, natural gas and aviation turbine fuel, as long as they remain outside GST
Input Tax Credit Consequences
This is the most important practical difference.
- Zero-rated supply: ITC is fully available. Since output is zero-rated, credit accumulates and can be claimed as refund under Section 54.
- Exempt supply: ITC attributable to exempt supplies is blocked under Section 17(2). If a registered person makes both taxable and exempt supplies, common credit must be reversed under Rule 42 and Rule 43.
- Nil-rated supply: Being a type of exempt supply, ITC is blocked.
- Non-taxable supply: Being included in exempt supply, ITC is blocked.
Practical Implications
A business exporting goods should classify exports as zero-rated, not exempt. It should not reverse ITC on export-related inputs. On the other hand, a hospital providing exempt healthcare services must reverse ITC on inputs used for exempt services, unless the services are zero-rated. Healthcare is generally exempt, so reversal is required.
Examples
- Export of software services = zero-rated supply. ITC available, refund possible.
- Sale of fresh vegetables = nil-rated supply. No output tax, ITC blocked.
- Healthcare services under exemption notification = exempt supply. ITC blocked.
- Sale of alcoholic liquor for human consumption = non-taxable supply, outside GST. No GST, ITC blocked.
