Difference Between Nil Rated, Exempted, Zero Rated, Non-GST in GST

Difference between nil rated and exempted in GST is one of those topics that looks simple but often gets misreported in returns. Both attract 0% tax. Yet, they are not the same in law. The classification affects Input Tax Credit, reporting, and compliance. If you misunderstand this, you may reverse ITC unnecessarily or later face notices for your enterprise.

Key Takeaways

• Nil rated supplies are taxable supplies with 0% GST rate.
• Exempted supplies are specifically exempted by notification under the GST law.
• ITC is eligible on zero rated and ineligible on nil rated and exempt.
• Zero rated supplies are mainly exports and SEZ supplies, with ITC benefits.
• Non-GST supplies fall completely outside the purview of GST.
• The difference between nil rated zero rated and exempted in GST directly impacts ITC eligibility and reporting in GSTR-3B.

What is Nil Rated?

Nil rated supplies are taxable supplies charged at 0% GST. The goods or services fall under GST. The rate is simply zero. Example of nil rated goods:

• Salt
• Unbranded natural honey
• Fresh milk in many cases

You must report nil rated supplies in your returns. They are not ignored. Since output tax is zero, you cannot claim ITC on purchases made for such supplies. If you deal only in nil rated goods, ITC shall not be available. As a result, the GST paid on inward supplies, used to make nil rated outward supplies, becomes a cost to the business. However, if inward supplies are used for both taxable supplies as well as nil-rated supplies, common credit rules shall apply.

Many businesses confuse nil rated with exempt. This is where the difference between nil rated and exempt goods becomes relevant.

Note that GST registration is compulsory where the business is exclusively dealing with nil rated goods as these are taxable supplies, where total turnover exceeds threshold limits. GSTR-1 and GSTR-3B reporting and filing applies for such supplies. 

What is Exempted?

Exempted supplies are those specifically exempted by the government through a notification under Section 11 of the CGST Act.

Here, the GST law applies. But the CBIC authority says no tax will be collected. Examples of exempted goods or services:

• Certain healthcare services
• Educational services provided by recognised institutions
• Agricultural services

The difference between exempt and nil rated GST lies in the law. Nil rated comes from the rate schedule. Exempted comes from a notification. However, their treatment remains the same.

Practical impact is that if you supply exempted goods or services, you cannot claim ITC on inputs used for such supplies. If you already claimed it, you must reverse proportionately as per the common credit rules. Ignoring this reversal becomes expensive during assessment. Accordingly, the input tax becomes a cost to the business.

Businesses dealing solely in exempted supplies are generally not required to register under GST, provided they do not cross special category triggers. Exempted supplies must be disclosed in GSTR-1 and GSTR-3B, and proportionate ITC reversal is mandatory where common inputs are used.

What is Zero Rated?

Zero rated supplies are defined under Section 16 of the IGST Act. These mainly include:

1. Exports of goods or services
2. Supplies to SEZ units or developers

Zero rated does not mean exempt. That is the biggest mistake people make. In zero rated supplies:

• No need to pay tax due to GST rate being 0
• You can claim full ITC
• You can claim a refund of unutilised ITC

This is the real difference between exempt, nil rated and zero rated. Zero rated protects ITC. Exempted and nil rated usually block it. So, when comparing the difference between nil rated and exempted supply in GST with zero rated, the ITC treatment is the deciding factor.

Exporters and SEZ suppliers must obtain GST registration even if their turnover is below the basic threshold, as zero rated benefits apply only to registered persons. Zero rated supplies require additional documentation such as LUT filing or payment of IGST with refund claims.

What is Non-GST Supplies?

Non-GST supplies fall completely outside the scope of GST law.

GST is not applicable at all. These are not taxable supplies under GST.

Examples:

• Alcohol for human consumption
• Petroleum crude
• Electricity in many cases

You report non-GST supplies separately in returns.

Unlike nil rated or exempted, these are not covered under the GST rate schedule or exemption notifications. They are simply outside the law. Accordingly, no GST registration is required if they exclusively deal with non-GST supplies. Non-GST supplies must still be reported in returns for disclosure purposes, though no tax liability arises. Input taxes paid on purchases related to non-GST supplies are not creditable under GST, which can increase overall cost structures.

The difference between nil rated, exempted supply and non-GST supplies is about coverage. Nil rated and exempted items are within the scope of GST. Non-GST is outside.

If your finance team mixes these up, your GSTR-3B reporting will go wrong. Eventually, our enterprise could potentially be issued a notice.
