When a business makes both taxable and exempt supplies, full Input Tax Credit (ITC) cannot be retained on common inputs, input services, and capital goods. The GST law requires proportionate reversal of ITC attributable to exempt supplies.
This comprehensive guide explains when ITC must be reversed on exempt supplies, the calculation methodology, and practical compliance requirements.
The Legal Framework: Section 17(2)
The Rule
Section 17(2) of the CGST Act restricts input tax credit (ITC) where inputs or input services are used for both taxable (including zero-rated) and exempt supplies.
The Requirement
The portion attributable to taxable supplies is eligible, while the portion attributable to exempt supplies or non-business use is required to be reversed.
What Are Exempt Supplies?
Definition
Exempt supply under GST includes:
- Nil-rated supplies which attract nil rate of tax
- Non-taxable supplies
- Supplies on which the recipient is liable to pay tax on reverse charge basis
- Transactions in securities
- Sale of building when entire consideration is received after completion
Rules for ITC Reversal
Rule 42: Inputs and Input Services
Rule 42 applies to inputs and input services. It governs the reversal of ITC when inputs or input services are used partly for taxable supplies and partly for exempt supplies.
Rule 43: Capital Goods
Rule 43 applies to capital goods. It governs the reversal of ITC on capital goods used partly for taxable supplies and partly for exempt supplies.
How ITC Reversal Works: Rule 42
Step 1: Identify Common Credit
Identify the total ITC on inputs and input services that are used for both taxable and exempt supplies.
Step 2: Calculate Exempt Turnover Proportion
Calculate the proportion of exempt turnover to total turnover.
Step 3: Reverse Proportionate ITC
Reverse the proportionate ITC attributable to exempt supplies.
Step 4: Report in GSTR-3B
Report the ITC reversal in GSTR-3B.
How ITC Reversal Works: Rule 43
Step 1: Identify Capital Goods
Identify capital goods used for both taxable and exempt supplies.
Step 2: Apply Useful Life
ITC reversal on capital goods is calculated over the useful life of 60 months.
Step 3: Calculate Proportionate Reversal
Calculate the proportionate reversal based on exempt turnover proportion.
Step 4: Report in GSTR-3B
Report the ITC reversal in GSTR-3B.
Practical Example of Rule 42 Reversal
Scenario: ABC Traders has:
- Total turnover: ₹100,00,000
- Exempt turnover: ₹20,00,000
- Common ITC on inputs and input services: ₹10,00,000
Calculation:
- Exempt turnover proportion: ₹20,00,000 / ₹100,00,000 = 20%
- ITC to be reversed: ₹10,00,000 × 20% = ₹2,00,000
Result: ABC Traders must reverse ₹2,00,000 of ITC in GSTR-3B.
ITC Reversal: Complete Reversal vs Proportionate Reversal
Complete Reversal
Inputs exclusively used for exempt supplies retain no ITC—full reversal required.
Proportionate Reversal
Inputs used for both taxable and exempt supplies require proportionate reversal.
No Reversal
Inputs exclusively used for taxable supplies retain full ITC.
ITC Reversal: Common Mistakes
1. Not Reversing ITC for Exempt Supplies
Where inputs, input services or capital goods are used for both taxable and exempt supplies, full ITC cannot be retained.
2. Incorrect Calculation of Exempt Turnover
Exempt turnover includes RCM supplies and transactions in securities.
3. Using the Wrong Rule
Rule 42 applies to inputs and input services. Rule 43 applies to capital goods.
4. Not Reporting in GSTR-3B
ITC reversal must be reported in GSTR-3B.
When ITC Reversal Is Not Required
Exclusively Taxable Supplies
If inputs, input services, or capital goods are used exclusively for taxable supplies, no reversal is required.
Zero-Rated Supplies
Zero-rated supplies (exports) are treated as taxable supplies for ITC purposes. No reversal is required for exports.
ITC Reversal: Compliance Checklist
- Identify all common inputs, input services, and capital goods
- Calculate the proportion of exempt turnover to total turnover
- Apply Rule 42 for inputs and input services
- Apply Rule 43 for capital goods
- Report ITC reversal in GSTR-3B
