Exempt Supplies and Nil-Rated, Non-GST Supplies
Updated 5 October 2026 · Fact-checked
Exempt supply under section 2(47) CGST covers nil-rated supplies, supplies wholly exempt by notification, and non-taxable supplies. To solve a question, classify each supply, deny ITC on inputs used only for exempt supplies, and reverse common credit in the ratio of exempt turnover to total turnover under section 17 and Rules 42 and 43.
Understand Exempt Supplies and Nil-Rated, Non-GST Supplies
GST law uses several labels for supplies that carry no tax in the customer's invoice. They look alike but behave differently. The exam tests whether you can tell them apart and then apply the ITC consequence.
Nil-rated supply is a supply that is taxable in law but the rate is 0%. It sits in the rate schedules or rate notifications with a zero rate.
Wholly exempt supply is a supply on which the government has granted full exemption by notification under section 11 of the CGST Act (or section 6 of the IGST Act). The supply is leviable, but the levy is waived.
Non-taxable supply (section 2(78)) is a supply that is not leviable to tax under the CGST Act or the IGST Act at all. Examples are alcoholic liquor for human consumption, and petroleum crude, high speed diesel, motor spirit, natural gas and aviation turbine fuel, which are outside GST until the Council recommends otherwise.
The key link is section 2(47). Exempt supply means a supply of goods or services or both that attracts nil rate of tax, or that is wholly exempt under section 11 CGST or section 6 IGST, and it includes non-taxable supply. So for ITC purposes, all three labels fall under one word: exempt supply. Zero-rated supply (exports and supplies to SEZ) is not exempt. It is a taxable supply with ITC allowed.
Why this matters: under section 17(2), if you use inputs or input services partly for taxable (including zero-rated) supplies and partly for exempt supplies, ITC is allowed only for the part attributable to taxable supplies. Rules 42 and 43 give the method.
Two points decide the reversal ratio. First, the value of exempt supply is as defined in the Explanation to section 17. It excludes the value of supplies on which the recipient is liable to pay tax on reverse charge. It includes transactions in securities, sale of land and, subject to para 5(b) of Schedule II, sale of building. Second, under Rule 42 the denominator is the total turnover in the State or Union territory of the registered person for the period concerned, reduced by the exclusions specified in Rule 42 and the Explanation to section 17. Do not use 'aggregate turnover' of section 2(6) here.
Key rules to remember
- Exempt supply (section 2(47) CGST)
- Exempt supply = nil-rated supply + wholly exempt supply (section 11 CGST / section 6 IGST) + non-taxable supply
- Non-taxable supply is expressly included. Zero-rated supply is not part of exempt supply.
- Non-taxable supply (section 2(78) CGST)
- Supply not leviable to tax under the CGST Act or the IGST Act
- It differs from a wholly exempt supply, which is leviable but exempted by notification.
- ITC restriction (section 17(2))
- Eligible ITC on common inputs = credit attributable to taxable supplies (including zero-rated supplies)
- Credit on inputs used exclusively for exempt supplies is not available.
- Rule 42 common credit reversal (inputs and input services)
- Reversal = Common credit × (Value of exempt supplies ÷ Total turnover in the State/UT of the registered person for the period)
- Common credit means total ITC less exclusive taxable credit, exclusive exempt credit, non-business credit and blocked credit. Value of exempt supplies is as defined in the Explanation to section 17, which excludes supplies on which the recipient pays tax under reverse charge. The denominator is total turnover in the State/UT, after the exclusions specified in Rule 42 and the Explanation to section 17, not 'aggregate turnover' under section 2(6). The reversal is worked provisionally each month and finalised as an annual computation on the annual common credit and annual turnover, with interest on any shortfall.
- Rule 43 capital goods
- Monthly credit Ta = ITC on the capital goods ÷ 60. Exempt portion Te = Ta × (Exempt turnover ÷ Total turnover of the tax period). Te is added to the output tax liability of the month, which reverses that part of the credit.
- Rule 43 applies to capital goods used or intended to be used partly for exempt supplies and partly for taxable supplies (or non-business use). The 60 months reflect a five-year life. The ratio is exempt turnover to total turnover of the tax period. Capital goods used exclusively for exempt supplies get no credit.
How to solve Exempt Supplies and Nil-Rated, Non-GST Supplies questions
Use this order for any question on exempt, nil-rated or non-GST supplies. Do not jump to numbers before the classification is clear.
- 1List every supply in the facts and tag each as taxable, zero-rated, nil-rated, wholly exempt or non-taxable.
- 2Check the source: a 0% entry in the rate schedule means nil-rated; a section 11 or section 6 IGST notification means wholly exempt; a supply outside the levy, such as alcohol for human consumption or petrol, is non-taxable.
- 3Apply section 2(47): put nil-rated, wholly exempt and non-taxable supplies together as exempt supplies. Keep exports and SEZ supplies out of this group.
- 4Group the inputs: used only for taxable or zero-rated supplies (full ITC), used only for exempt supplies (no ITC), blocked under section 17(5), non-business use, and common use.
- 5Compute common credit and the ratio. The numerator is the value of exempt supplies as defined in the Explanation to section 17 (it includes securities, land and, subject to para 5(b) of Schedule II, building, and excludes supplies on which the recipient pays tax under reverse charge). The denominator is the total turnover in the State/UT of the registered person for the period, as per Rule 42 and the Explanation to section 17.
- 6Reverse common credit × ratio under Rule 42. For capital goods, take 1/60 of the ITC per month (Ta) under Rule 43, find its exempt portion Te using the ratio of exempt turnover to total turnover of the tax period, and add Te to the output tax liability of the month.
- 7State the conclusion: eligible ITC, amount reversed, and that it is adjusted in the return, with annual adjustment and interest if reversed less than due.
Quickest way: Three-column tagging and ratio
When to use it: Use this when the question gives many supplies and a table of ITC amounts and you have limited time.
- Draw three columns: Taxable or zero-rated, Exempt (nil, wholly exempt, non-taxable), Common.
- Place each supply and each ITC amount in a column in one pass.
- Cross out exclusive exempt ITC and blocked ITC straight away.
- Ratio = exempt turnover ÷ total turnover. Multiply it by common credit only.
- Eligible ITC = exclusive taxable credit + common credit − reversal. Write one line of provision and conclusion.
Common mistakes in Exempt Supplies and Nil-Rated, Non-GST Supplies
Treating non-taxable supply as outside the reversal rule because it is 'not under GST'.
Students think non-GST means no GST consequence at all.
Fix: Section 2(47) includes non-taxable supply in exempt supply. ITC on inputs used for it is restricted under section 17(2).
Treating exports or SEZ supplies as exempt and reversing ITC.
Both carry no tax on the invoice, so they look similar.
Fix: These are zero-rated and taxable. ITC is allowed, and the tax or refund route applies.
Applying the exempt turnover ratio to total ITC instead of only common credit.
Students rush to use the formula without separating the credit.
Fix: First remove exclusive taxable, exclusive exempt, blocked and non-business credit. Apply the ratio only to the common balance.
Saying nil-rated and wholly exempt are the same thing.
Both result in no tax being paid, and the ITC result is the same.
Fix: Nil-rated means a 0% rate is prescribed. Wholly exempt means leviable but exempted by notification under section 11. State the difference and then the common ITC effect.
Getting the value of exempt supply wrong by ignoring the Explanation to section 17, for example leaving out sale of land or securities, or counting reverse charge supplies.
Students look only at supplies listed as exempt in notifications.
Fix: Read the Explanation to section 17. Include transactions in securities, sale of land and, subject to para 5(b) of Schedule II, sale of building. Exclude supplies on which the recipient pays tax under reverse charge.
Working Rule 43 with a fresh monthly turnover ratio or forgetting to add the exempt portion to the output tax liability.
Students read 'spread over 60 months' as a month-by-month ratio exercise.
Fix: Take 1/60 of the capital goods ITC as Ta each month, apply the exempt-to-total turnover ratio of the tax period to find Te, and add Te to the output tax liability of the month.
Worked examples
Example 1
Ravi Traders is registered in Maharashtra. During a tax period it sells (a) fresh vegetables, which are wholly exempt by notification under section 11, (b) motor spirit from its fuel counter, (c) laptops taxable at 18%, and (d) garments exported under letter of undertaking. Classify each supply and state which are exempt supplies under section 2(47).
Show the solution
- Fresh vegetables: leviable but fully exempted by a section 11 notification, so a wholly exempt supply.
- Motor spirit: outside the levy of GST at present, so a non-taxable supply under section 2(78).
- Laptops at 18%: a taxable supply.
- Exported garments: a zero-rated supply, which is taxable with ITC allowed and not exempt.
- Section 2(47) covers nil-rated, wholly exempt and non-taxable supplies. So (a) and (b) are exempt supplies.
Answer: Vegetables are wholly exempt and motor spirit is non-taxable; both are exempt supplies under section 2(47). Laptops are taxable and exports are zero-rated, so neither is exempt. Common inputs used for (a) and (b) attract ITC restriction under section 17(2) and Rule 42.
Example 2
Meera & Co. is registered in one State. For the financial year, this is its final annual computation under Rule 42(2), using annual figures. Total ITC for the year is ₹4,50,000. Of this, ₹1,00,000 relates to inputs used only for taxable supplies, ₹40,000 to inputs used only for exempt supplies, ₹10,000 is blocked under section 17(5), and the rest is common credit. Total turnover in the State for the year (as relevant for Rule 42) is ₹80,00,000, of which the value of exempt supplies (including non-taxable) is ₹20,00,000. Compute the reversal and the eligible ITC (ignore non-business use).
Show the solution
- Common credit for the year = 4,50,000 − 1,00,000 − 40,000 − 10,000 = ₹3,00,000.
- Exempt ratio = annual exempt value ÷ annual total turnover in the State = 20,00,000 ÷ 80,00,000 = 25%.
- Reversal on annual common credit = 3,00,000 × 25% = ₹75,000.
- Eligible common credit = 3,00,000 − 75,000 = ₹2,25,000.
- Eligible ITC = exclusive taxable 1,00,000 + eligible common 2,25,000 = ₹3,25,000.
- Check: 4,50,000 − 40,000 − 10,000 − 75,000 = ₹3,25,000, which matches.
Answer: The annual reversal under Rule 42 is ₹75,000. Eligible ITC is ₹3,25,000. The ₹40,000 exclusive exempt credit and ₹10,000 blocked credit are never available. During the year the reversal is worked monthly on provisional figures; this annual figure is the final computation, and any difference from the monthly reversals is adjusted with interest if short.
Exam tips
- Start every answer with the definition in section 2(47) and state that non-taxable supply is included. This earns the first mark in most answers.
- In MCQ cases, check first whether the supply is zero-rated. Exports and SEZ supplies are a favourite trap against 'exempt'.
- In calculations, show the common credit step clearly. Marks are given for the method even if the final figure is off.
- Write answers in provision, facts, conclusion form: section 17(2) and Rule 42 or 43, then the figures, then the amount reversed.
- Do not quote notification numbers or section numbers you are not sure about. Describe the rule in words.

Exempt Supplies and Nil-Rated, Non-GST Supplies: frequently asked questions
What is the difference between nil-rated, exempt and non-GST supply?
Nil-rated supply is taxable in law but has a 0% rate. Wholly exempt supply is leviable but exempted by notification under section 11. Non-GST (non-taxable) supply is not leviable under the CGST or IGST Act at all. For ITC, section 2(47) groups all three as exempt supply.
Is non-taxable supply the same as exempt supply?
Not exactly, but the definition of exempt supply in section 2(47) includes non-taxable supply. So non-taxable supplies are treated like exempt supplies for ITC restriction under section 17.
Is ITC allowed on inputs used for exempt supplies?
No. Section 17(2) allows credit only for the part attributable to taxable supplies, including zero-rated supplies. Credit on inputs used only for exempt supplies is not available, and common credit is reversed under Rule 42 or Rule 43.
Are exports exempt supplies?
No. Exports are zero-rated supplies. They are treated as taxable, ITC is allowed, and you can export under bond or letter of undertaking or pay IGST and claim a refund.
