There is no universal GST rate or exemption that can be selected from a product’s everyday name. For each transaction, identify the precise goods or service, classify it under the GST framework, check the current rate entry, and then test any exemption notification and its conditions. The result can also change when a supply is bundled, exported, made to an SEZ, or affected by place-of-supply rules.
A taxable supply at a notified rate normally carries GST; an exempt supply is relieved by the Act or an applicable notification. Nil-rated, non-taxable and zero-rated supplies are related but not interchangeable categories, especially for input tax credit (ITC). This guide gives a repeatable method for deciding which treatment applies, documenting the decision and avoiding invoice and credit errors.

The short answer: rate first, exemption separately
Begin with the transaction as it actually occurs, not with a catalogue label or marketing description. Record what is supplied, every component included, the supplier and recipient, the place and date of supply, and the contractual terms. Then determine the legal classification and locate the corresponding entry in the current GST rate materials.
After finding the apparent rate, perform a separate exemption check. Section 11 of the Central Goods and Services Tax (CGST) Act, 2017 permits exemptions by notification, including conditional and partial exemptions. An exemption applies only when the supply fits the notification’s wording and every relevant condition, limitation, exclusion and effective date is satisfied. A rate table entry does not, by itself, prove that a supply is exempt, and an exemption notification does not automatically apply to a similar-looking product or service.

For an intra-State transaction, the result may be CGST plus SGST or UTGST. For an inter-State transaction, it may be IGST. Place-of-supply rules determine which structure applies; they do not change the need to classify the underlying supply correctly.
How the main GST categories differ
| Treatment | Legal idea | Tax charged to customer | Typical ITC consequence | Document and qualification |
|---|---|---|---|---|
| Taxable at a notified rate | The supply falls within a taxable rate entry and is not relieved by an applicable exemption. | CGST and SGST/UTGST, or IGST, at the applicable notified rate. | ITC is generally available subject to the Act, rules, eligibility and apportionment requirements. | Usually a tax invoice showing the applicable tax. Rate, classification and place of supply must be supported. |
| Exempt supply | The supply is covered by a statutory or notification-based exemption, subject to its conditions. | No GST is collected under that exemption; an exemption can be full or partial. | CBIC’s GST FAQ states that no ITC is available for exempt supplies. Common credit may require attribution or reversal. | A registered supplier generally issues a bill of supply for exempt goods or services instead of a tax invoice. |
| Nil-rated (taxable at 0%) | The rate schedule assigns a nil rate to the classified supply. | Tax at 0%. | CBIC’s FAQ includes nil-rated supplies within “exempt supply” for its ITC explanation. | Confirm the exact rate entry and document requirements; do not infer treatment from the product’s name. |
| Non-taxable supply | CGST Act section 2(78) defines it as a supply of goods or services that is not leviable under the CGST Act or the IGST Act. | No levy under those Acts. | Do not assume the same treatment as a taxable or zero-rated supply; analyze the statutory basis and related credit rules. | Document why the levy does not apply and check any other applicable law. |
| Zero-rated supply | IGST Act section 16 covers exports and supplies to an SEZ developer or SEZ unit, subject to statutory requirements. | Tax may be supplied under the permitted route, including procedures for export or SEZ supplies. | Zero-rating has its own credit and refund framework; it should not be collapsed into the exempt-supply ITC rule. | Export or SEZ evidence, declarations and refund conditions must be met. |
The terms “zero tax,” “0%,” “exempt” and “zero-rated” therefore cannot be used as synonyms. A nil-rated supply is taxable at a zero rate in the schedule, while a zero-rated supply is a special IGST Act category designed to preserve specified credit and refund treatment. CBIC’s FAQ uses “exempt supply” broadly to include nil-rated and non-taxable supplies for its ITC answer, but the underlying statutory concepts still matter when filing returns, claiming credit or seeking a refund.
A step-by-step method for deciding the treatment
1. Write down the complete transaction
Create a transaction record before searching a rate table. Include:
Free tools Windows power users keep installed
One-click scans. No signup required.
- The goods, service or both, with technical specifications, use, quantity and condition.
- Everything supplied together, such as installation, freight, warranty, consumables, software access or training.
- The supplier’s and recipient’s identities and capacities, including whether either is registered or falls within a special statutory category.
- The contract price, discounts, reimbursements and any consideration paid in kind.
- The supplier location, recipient location, delivery location and date of supply.
- Whether the transaction is domestic, an export, or a supply to an SEZ developer or unit.
Keep the purchase order, agreement, technical literature and correspondence that establish these facts. A classification based only on a short invoice description is vulnerable if the contract shows that additional elements were supplied.
2. Determine the legal classification
Match the actual characteristics to the relevant goods or service description and classification under the GST framework. Classification may depend on composition, processing, intended use, function, packaging or the way a service is performed. A trade name, brand name or broad sector label is not determinative.
For goods, compare the product’s technical details with the relevant tariff or rate description. For services, identify the nature of the service delivered rather than the customer’s reason for buying it. If two classifications appear plausible, record the competing descriptions and the factual reason one fits better. Obtain a formal classification view where the tax exposure is material or the wording is uncertain.
3. Check the current notified rate
Use the current CBIC rate materials and the applicable notification entry for the classification. Read the complete entry, not only the percentage displayed in a summary table. Check whether the entry is restricted by description, value, packaging, end use, recipient, stage of supply or another condition.

Then determine whether the levy is CGST plus SGST/UTGST or IGST by applying the place-of-supply rules. A rate expressed as a percentage does not answer the tax-type question. Preserve the notification number, entry reference and effective date in the transaction file.
4. Search for an exemption independently
After identifying the apparent rate, review the current goods or services exemption notifications and later amendments. Confirm all of the following:
- The notification covers the same legal supply and classification.
- The exemption is in force on the date of supply.
- Any recipient, supplier, territory, value or turnover limitation is met.
- Any certificate, declaration, registration, end-use or procedural condition is satisfied.
- No exclusion, proviso or later amendment removes the supply from the relief.
- The exemption is full, partial or conditional, and the invoice reflects that result.
An exemption can be conditional. If one condition fails, the transaction may revert to the applicable taxable treatment or lose only the conditional portion, depending on the notification’s wording. Do not treat a general description such as “healthcare,” “education” or “agricultural” as a blanket exemption.
5. Test whether the supply is nil-rated, non-taxable or zero-rated
Use the statutory category that actually fits. A nil rate is found in the rate schedule. A non-taxable supply is one that is not leviable under the CGST or IGST Act, as described in section 2(78) of the CGST Act. A zero-rated supply is governed by section 16 of the IGST Act and includes exports and supplies to an SEZ developer or unit when statutory requirements are met.
These distinctions affect ITC, refund eligibility, reporting and documentation. Never select “zero-rated” merely because the invoice shows no tax, and never claim export-style credit or refund treatment for an ordinary exempt domestic supply.
6. Resolve bundled transactions
If two or more goods or services are supplied together, apply the composite-supply and mixed-supply rules before selecting a rate or exemption. A composite supply contains multiple supplies that are naturally bundled and supplied together in the ordinary course of business, with one principal supply. It is treated as the principal supply.
A mixed supply combines two or more individual supplies for a single price without being a composite supply. It is treated as the particular supply that attracts the highest rate. The classification is fact-dependent: examine how the contract presents the components, whether customers ordinarily expect them together, whether each component can be supplied separately, and whether one element is clearly predominant.
7. Assess ITC and invoicing consequences
Once the treatment is settled, determine the credit and document consequences. CBIC’s GST FAQ states: “Exempt supply includes Nil rated (taxable at 0%) and non-Taxable supplies and no ITC is available for such supplies.” A business making both taxable and exempt supplies may therefore need to attribute or reverse common input tax credit under the applicable rules.

The amount associated with exempt turnover is allocated in relation to exempt turnover and total turnover, using the records and method required by the current rules. Keep purchase invoices, expense allocation workings and turnover calculations that support the result.
CBIC’s sectoral FAQ says that a registered person supplying exempt goods or services generally issues a bill of supply rather than a tax invoice. The bill of supply does not show a tax rate or tax amount charged. Verify the current invoice rules and any transaction-specific exception before issuing the document.
8. Freeze the evidence and effective date
Record the classification basis, rate entry, exemption notification and entry number, conditions tested, place-of-supply conclusion, composite or mixed-supply analysis, invoice type and the effective date. Save the version of the notification or Gazette text used. GST rate and exemption tables can be amended; a result that was correct for an earlier period may not be correct for a later invoice.
Input tax credit: why the distinction changes the economics
Tax not collected from the customer does not necessarily mean that the supplier’s input costs are recoverable. For an exempt domestic supply, the supplier generally cannot take ITC attributable to that supply. Where inputs or input services support both taxable and exempt supplies, common credit is apportioned and the exempt portion may have to be reversed under the current rules.

Zero-rated supplies follow a different policy. Exports and qualifying SEZ supplies are intended to leave Indian consumption taxes at the border while preserving specified credit and refund mechanisms under the IGST Act. The supplier must satisfy the statutory conditions and documentary requirements for the selected route. A domestic supply that happens to carry no tax on its invoice does not acquire zero-rated status.
When reviewing a transaction, ask three separate questions: Was GST charged to the recipient? Is the supply legally exempt, nil-rated, non-taxable or zero-rated? What credit or refund mechanism does that category permit? Keeping those questions separate prevents a “no tax” conclusion from producing an incorrect ITC claim.
Invoices, bills of supply and records
When a tax invoice is appropriate
A taxable supply normally requires a tax invoice showing the classification or description, taxable value, rate, amount of CGST, SGST/UTGST or IGST, and other particulars required by the current invoice rules. The tax type must correspond to the place-of-supply conclusion. If a notification grants only partial relief, show the taxable portion and treatment required by that notification rather than treating the whole transaction as exempt.
When a bill of supply is appropriate
A registered supplier of exempt goods or services generally issues a bill of supply instead of a tax invoice. Because no GST is charged under the exemption, the bill does not contain a tax rate or tax amount charged. Keep the exemption reference and supporting evidence in internal records even when the document itself does not display tax.

How to analyze a bundle: composite versus mixed supply
Composite supply
Suppose a contract promises a principal service together with elements that are naturally bundled with it and ordinarily supplied as one package. If the facts satisfy the statutory composite-supply definition, the whole supply is treated as the principal supply. The principal supply’s rate and exemption status then govern the composite supply, subject to the exact law and notification wording.
Mixed supply
If a package combines independent goods or services for one price but is not naturally bundled, it is a mixed supply. The statutory rule treats it as the component attracting the highest rate. A supplier cannot avoid that result by applying the lowest component rate to the package or by describing every item as a separate sale when the contract and pricing show one combined supply.
Because the distinction depends on real commercial facts, retain the customer quotation, pricing structure, delivery sequence and evidence of how the components are ordinarily supplied. If the bundle changes over time, recheck the analysis for the revised package.

Using a product’s popular name
Problem: A product is assigned a rate based on a familiar name or industry category. Correction: Compare its composition, function, use and technical description with the legal entry, and preserve the classification reasoning.
Treating every 0% result as zero-rated
Problem: No GST appears on the invoice, so the supplier claims export-style ITC or refund treatment. Correction: Establish whether the supply is nil-rated, exempt, non-taxable or zero-rated under the relevant statute. Only a qualifying section 16 supply receives zero-rating treatment.
Stopping after finding a rate
Problem: The rate table is checked but a conditional exemption or exclusion is missed. Correction: Search exemption notifications separately and read the complete entry, provisos and amendments.
Ignoring effective dates
Problem: A later notification or amendment is applied to an earlier invoice, or an old exemption is used after it changed. Correction: Match the notification and rate to the date of supply and retain the effective Gazette text.
Claiming all purchase credit despite exempt turnover
Problem: Common inputs are used for both taxable and exempt supplies, but no attribution or reversal is made. Correction: Apply the current ITC apportionment rules, maintain a defensible turnover split and reconcile it periodically.
Issuing the wrong document
Problem: An exempt supply is documented with a tax invoice showing a tax amount, or a taxable supply is documented as exempt. Correction: Confirm the legal treatment before invoicing and verify current invoice-rule exceptions.
Assuming a sector is wholly exempt
Problem: A broad label such as “education” or “medical” is treated as a blanket relief. Correction: Test the actual service, recipient, provider, value and conditions in the relevant entry.
A practical decision checklist
- Describe every good, service and bundled element in the contract.
- Identify supplier, recipient, locations, date and transaction type.
- Select the most defensible legal classification.
- Locate the current notified rate and identify CGST/SGST/UTGST or IGST.
- Read the full rate entry, exclusions and effective date.
- Search current exemption notifications for the same classification.
- Test each exemption condition, threshold, recipient limit and certification.
- Classify any bundle as composite or mixed before applying a treatment.
- Determine whether the result is taxable, exempt, nil-rated, non-taxable or zero-rated.
- Calculate ITC eligibility, common-credit attribution and any reversal.
- Choose a tax invoice or bill of supply and include required particulars.
- File the notification, amendment, evidence and reasoning with the transaction records.
When to obtain transaction-specific advice
Escalate the issue when two tariff or service classifications are plausible, a notification condition is difficult to interpret, the bundle contains a high-value component, the supply crosses State or national borders, an export or SEZ benefit is being claimed, or the ITC and refund amount is material. A professional should review the actual contract and effective law, not just the invoice description.
CBIC’s online FAQs and rate materials are useful starting points, but summaries can lag amendments. For a live filing or disputed transaction, verify the currently effective CGST Act, IGST Act, rules and Gazette notifications. The final file should show not only the conclusion but also the facts and authority that make the conclusion reproducible.
