The refund of accumulated Input Tax Credit (ITC) due to inverted duty structure is calculated using a specific formula under Rule 89(5) of the CGST Rules. This comprehensive guide explains the formula, its components, and how to calculate the refund amount.
Understanding Rule 89(5)
What Is Rule 89(5)?
Rule 89(5) of the CGST Rules prescribes the formula for calculating the refund of accumulated ITC due to inverted duty structure. This rule applies when the tax rate on inputs is higher than the tax rate on outputs.
When Does Rule 89(5) Apply?
Rule 89(5) applies when:
- ITC has accumulated due to inverted duty structure
- The business is claiming refund of accumulated ITC
- The supplies are taxable (not exempt)
The Formula
Rule 89(5) Formula
Refund Amount = (Turnover of inverted-rated supplies × Net ITC / Adjusted Total Turnover) - Tax payable on inverted-rated supplies
Formula Components
1. Turnover of inverted-rated supplies The value of supplies on which the output tax rate is lower than the input tax rate. This includes only the supplies that are affected by the inverted duty structure.
2. Net ITC The total ITC availed on inputs during the relevant period. This includes ITC on all inputs, not just those used for inverted-rated supplies.
3. Adjusted Total Turnover The total turnover of the business, adjusted for:
- Exempt supplies
- Zero-rated supplies
- Supplies on which tax is paid under reverse charge
4. Tax payable on inverted-rated supplies The tax payable on the inverted-rated supplies (output tax).
Step-by-Step Calculation
Step 1: Identify the Period
Identify the period for which the refund is being claimed (usually a tax period or financial year).
Step 2: Calculate Turnover of Inverted-Rated Supplies
Calculate the value of supplies where the output tax rate is lower than the input tax rate.
Step 3: Calculate Net ITC
Calculate the total ITC availed during the period.
Step 4: Calculate Adjusted Total Turnover
Calculate the total turnover adjusted for exempt supplies, zero-rated supplies, and RCM supplies.
Step 5: Apply the Formula
Apply the formula:
- Step 5a: (Turnover of inverted-rated supplies × Net ITC) / Adjusted Total Turnover
- Step 5b: Subtract Tax payable on inverted-rated supplies
- Result: Refund Amount
Practical Example
Example
Facts:
- Turnover of inverted-rated supplies: ₹10,00,000
- Net ITC: ₹1,80,000
- Adjusted Total Turnover: ₹50,00,000
- Tax payable on inverted-rated supplies: ₹50,000 (5% of ₹10,00,000)
Calculation:
- (₹10,00,000 × ₹1,80,000) / ₹50,00,000 = ₹36,000
- ₹36,000 - ₹50,000 = -₹14,000
Result: The refund amount is ₹0 (as the calculation is negative). No refund is available in this case.
Example with Positive Refund
Facts:
- Turnover of inverted-rated supplies: ₹10,00,000
- Net ITC: ₹2,50,000
- Adjusted Total Turnover: ₹50,00,000
- Tax payable on inverted-rated supplies: ₹50,000 (5% of ₹10,00,000)
Calculation:
- (₹10,00,000 × ₹2,50,000) / ₹50,00,000 = ₹50,000
- ₹50,000 - ₹50,000 = ₹0
Result: The refund amount is ₹0 (no excess ITC remains after setting off against output tax).
Important Points
1. Refund Only to Extent of Accumulated ITC
Refund is available only to the extent of ITC that has accumulated. If the ITC is fully utilized, no refund is available.
2. No Refund for Capital Goods
In most cases, ITC on capital goods is not eligible for refund under inverted duty structure.
3. Exempt Supplies
If exempt supplies are made, the ITC attributable to exempt supplies must be reversed.
4. Unjust Enrichment
Refund may be reduced if the burden of tax has been passed on to the customer.
