Module A: Introduction & Importance of Composition Tax Under GST

The Goods and Services Tax (GST) composition scheme is a simplified taxation mechanism designed for small taxpayers with turnover below specified thresholds. Introduced under Section 10 of the CGST Act, 2017, this scheme allows eligible businesses to pay tax at a fixed percentage of their turnover instead of following the regular GST compliance procedures.

Key Benefits of the Composition Scheme:

• Reduced Compliance: Quarterly returns instead of monthly
• Lower Tax Rates: Fixed percentage based on business type
• No Input Tax Credit: Cannot claim ITC on purchases
• Limited Territory: No inter-state supplies allowed
• Cash Flow Advantage: Pay tax only on collected amounts

The scheme is particularly beneficial for small businesses, traders, and manufacturers who want to minimize their compliance burden while maintaining tax compliance. According to Department for Promotion of Industry and Internal Trade data, over 1.2 million businesses were registered under the composition scheme as of 2023, representing approximately 18% of all GST registrations.

Module C: Formula & Methodology Behind the Calculation

The composition tax calculation follows a precise mathematical formula based on GST regulations. Here’s the detailed methodology:

1. Taxable Turnover Calculation

The first step is determining the taxable turnover by subtracting exempt supplies from total turnover:

Taxable Turnover = Total Turnover – Exempt Sales

2. Rate Determination

Composition rates vary by business type and state category:

Business Type	Regular States	Special Category States
Manufacturers & Traders	1% of taxable turnover	0.5% of taxable turnover
Restaurants (non-alcoholic)	5% of taxable turnover	2.5% of taxable turnover
Service Providers	6% of taxable turnover	3% of taxable turnover

3. Tax Liability Calculation

The final tax liability is calculated by applying the determined rate to the taxable turnover:

Tax Liability = Taxable Turnover × Applicable Rate

4. Effective Tax Rate

This shows the actual tax burden as a percentage of total turnover:

Effective Rate = (Tax Liability / Total Turnover) × 100

5. Special Considerations

• Threshold Limits: Businesses exceeding ₹1.5 crore (₹75 lakh for special states) must switch to regular GST
• Inter-state Supplies: Composition dealers cannot make inter-state sales
• E-commerce Restrictions: Cannot supply through e-commerce operators
• Input Tax Credit: Cannot claim ITC on purchases
• Bill of Supply: Must issue “Bill of Supply” instead of tax invoices

Module G: Interactive FAQ About Composition Tax

Who is eligible for the GST composition scheme?

Eligibility criteria include:

• Businesses with annual turnover below ₹1.5 crore (₹75 lakh for special category states)
• For service providers, turnover must be below ₹50 lakh
• Not engaged in inter-state supplies
• Not supplying through e-commerce operators
• Not manufacturing ice cream, pan masala, or tobacco products

For complete eligibility details, refer to CBIC’s official notification.

What are the key differences between composition scheme and regular GST?

Feature	Composition Scheme	Regular GST
Tax Rate	Fixed (1%-6%)	Varies (0%-28%)
Compliance	Quarterly returns	Monthly returns
Input Tax Credit	Not available	Available
Inter-state Sales	Not allowed	Allowed
E-commerce	Not allowed	Allowed
Billing	Bill of Supply	Tax Invoice
Threshold	₹1.5 crore (₹75 lakh)	No upper limit

How do I migrate from regular GST to composition scheme?

Migration process involves these steps:

1. Ensure you meet all eligibility criteria
2. File Form CMP-02 on the GST portal before the beginning of the financial year
3. For mid-year migration, file Form CMP-02 and wait for approval
4. File Form ITC-03 to reverse any input tax credit
5. Start issuing “Bill of Supply” instead of tax invoices
6. File your first quarterly return Form CMP-08 by the due date

Important: You cannot migrate if you have any inter-state supplies in the current financial year.

What happens if I exceed the turnover limit?

If your turnover exceeds the threshold:

• You must switch to regular GST from the next financial year
• If exceeded during a quarter, you must switch immediately
• File Form CMP-04 to intimate the proper officer
• Start maintaining proper records for regular GST compliance
• You can reclaim input tax credit on stock held on the transition date

Penalty: Continuing under composition scheme after crossing the limit may attract penalties under Section 122 of the CGST Act.

Can I claim input tax credit under the composition scheme?

No, one of the fundamental conditions of the composition scheme is that you cannot claim input tax credit on your purchases. This is explicitly stated in Section 10(4) of the CGST Act.

However, there are two exceptions:

1. You can claim ITC on purchases made before opting into the composition scheme
2. When transitioning from composition to regular scheme, you can claim ITC on stock held on the transition date

The trade-off for not being able to claim ITC is the significantly lower compliance burden and fixed tax rates.

What records must I maintain under the composition scheme?

While compliance is simpler, you must maintain these records:

• Bill of Supply for all sales
• Purchase invoices (though ITC cannot be claimed)
• Quarterly summary of sales and purchases
• Stock registers
• Bank statements showing business transactions
• Records of exempt sales (if any)

Retention Period: All records must be maintained for at least 6 years from the end of the financial year to which they pertain.

How does the composition scheme work for restaurants?

Restaurants have special provisions under the composition scheme:

• Eligibility: Only restaurants not serving alcohol can opt for the scheme
• Tax Rate: 5% of turnover (2.5% in special category states)
• Billing: Must issue Bill of Supply (cannot charge GST separately)
• Input Tax Credit: Cannot claim ITC on food purchases, equipment, or other inputs
• Compliance: Must file quarterly CMP-08 and annual GSTR-4

Important Note: Restaurants under composition scheme cannot provide catering services (which would be considered inter-state supply if delivered outside their state).
