Rule 42 and Rule 43 of the CGST Rules are two critical provisions governing ITC reversal when inputs, input services, and capital goods are used partly for taxable supplies and partly for exempt supplies. While both deal with ITC reversal, they apply to different categories of inputs and have different calculation methodologies.
This comprehensive guide compares Rule 42 and Rule 43, explaining their key differences, applicability, and practical compliance.
Overview of Rule 42 and Rule 43
Rule 42: Inputs and Input Services
Rule 42 applies to inputs and input services. It governs the reversal of ITC when:
- Inputs and input services are used partly for taxable supplies (including zero-rated)
- And partly for exempt supplies or non-business purposes
Rule 43: Capital Goods
Rule 43 applies to capital goods. It governs the reversal of ITC on capital goods used:
- Partly for taxable supplies
- Partly for exempt supplies
- For non-business purposes
Key Differences Between Rule 42 and Rule 43
1. Applicability
| Aspect | Rule 42 | Rule 43 |
|---|---|---|
| Applicable to | Inputs and input services | Capital goods |
| Nature of items | Consumed in the course of business | Long-term assets |
2. Reversal Basis
| Aspect | Rule 42 | Rule 43 |
|---|---|---|
| Reversal basis | Proportion of exempt turnover to total turnover | Proportion of exempt turnover to total turnover |
| Additional factor | Not applicable | Useful life of 60 months |
3. Timing of Reversal
| Aspect | Rule 42 | Rule 43 |
|---|---|---|
| Reversal timing | In the period when inputs/input services are used | Spread over the useful life of the capital goods |
| Reversal frequency | Monthly/quarterly | Monthly/quarterly |
4. Method of Calculation
Rule 42:
- Identify common credit on inputs and input services
- Calculate exempt turnover proportion: Exempt turnover / Total turnover
- ITC to be reversed = Total common ITC Ć (Exempt turnover / Total turnover)
Rule 43:
- Identify common credit on capital goods
- Calculate exempt turnover proportion: Exempt turnover / Total turnover
- Calculate reversal per month: (Total ITC Ć Exempt turnover proportion) / 60 months
- Reversal = Reversal per month Ć Remaining useful life (in months)
5. Exempt Turnover Proportion
Both rules use the exempt turnover proportion, but the calculation method differs.
6. No Exempt Turnover Scenarios
| Scenario | Rule 42 | Rule 43 |
|---|---|---|
| If total turnover is zero | Proportionate reversal not applicable | Proportionate reversal not applicable |
| If exempt turnover is zero | Proportionate reversal not applicable | Proportionate reversal not applicable |
7. Reporting
Both rules require reporting in GSTR-3B, but the reporting tables may differ.
Rule 42: Calculation Example
Scenario: ABC Traders has:
- Total turnover: ā¹1,00,00,000
- Exempt turnover: ā¹20,00,000
- Common ITC on inputs and input services: ā¹10,00,000
Calculation:
- Exempt turnover proportion: ā¹20,00,000 / ā¹1,00,00,000 = 20%
- ITC to be reversed: ā¹10,00,000 Ć 20% = ā¹2,00,000
Result: ABC Traders must reverse ā¹2,00,000 of ITC.
Rule 43: Calculation Example
Scenario: XYZ Manufacturing purchases a machine for ā¹10,00,000. GST at 18% is ā¹1,80,000. The machine is used partly for taxable supplies and partly for exempt supplies.
- Useful life: 60 months
- Exempt turnover proportion: 20%
Calculation:
- Total ITC: ā¹1,80,000
- ITC attributable to exempt supplies: ā¹1,80,000 Ć 20% = ā¹36,000
- Reversal per month: ā¹36,000 / 60 = ā¹600
Result: XYZ Manufacturing must reverse ā¹600 per month for 60 months.
When to Apply Which Rule
Rule 42 Applies When
- You purchase raw materials (inputs) for manufacturing
- You receive consulting services (input services)
- The inputs/input services are consumed in the period
Rule 43 Applies When
- You purchase plant and machinery (capital goods)
- You purchase equipment and tools (capital goods)
- The capital goods have a useful life of more than one year
Common Mistakes to Avoid
1. Applying Rule 43 to Inputs and Input Services
Rule 43 applies only to capital goods. Inputs and input services are covered under Rule 42.
2. Applying Rule 42 to Capital Goods
Rule 42 applies only to inputs and input services. Capital goods are covered under Rule 43.
3. Incorrect Exempt Turnover Calculation
Both rules require accurate calculation of exempt turnover.
4. Incorrect Useful Life for Capital Goods
Rule 43 requires the useful life of 60 months for capital goods.
5. Not Reporting in GSTR-3B
Both rules require ITC reversal to be reported in GSTR-3B.
