Composition Scheme Tax Calculator: Complete Guide
Module A: Introduction & Importance of Composition Scheme
The composition scheme under GST is a simplified tax payment mechanism designed for small taxpayers with turnover below ₹1.5 crore (₹75 lakh for special category states). This scheme reduces compliance burden by allowing quarterly returns instead of monthly filings and offering lower tax rates compared to regular GST registration.
Key Benefits:
- Lower tax rates: Typically 1% for manufacturers/traders, 5% for restaurants
- Reduced compliance: Quarterly returns (CMP-08) instead of monthly GSTR-3B
- No input tax credit: Cannot claim ITC but pays lower taxes
- Limited documentation: Simplified record-keeping requirements
According to GST Portal, over 1.2 million taxpayers have opted for the composition scheme as of 2023, representing approximately 18% of all GST registrations. The scheme is particularly beneficial for small businesses in manufacturing, trading, and restaurant sectors.

Module C: Formula & Methodology
The calculator uses the following precise methodology:
1. Tax Rate Determination:
| Business Type | Regular State Rate | Special Category Rate |
|---|---|---|
| Manufacturer/Trader | 1% | 0.5% |
| Restaurant (non-alcoholic) | 5% | 2.5% |
| Service Provider | 6% (flat) | 6% (flat) |
2. Calculation Process:
- Annual Tax = Turnover × Applicable Rate
- Quarterly Tax = Annual Tax ÷ 4
- Effective Rate = (Annual Tax ÷ Turnover) × 100
3. Special Considerations:
- Turnover includes taxable, exempt, and export supplies
- Excludes inward supplies under reverse charge
- For restaurants: turnover includes food/drink sales only
- Service providers can only opt if turnover ≤ ₹50 lakh
The calculator automatically adjusts for the latest GST notifications from the Department of Revenue, including any rate changes or threshold adjustments.
Module D: Real-World Examples
Case Study 1: Manufacturing Business in Maharashtra
Scenario: Mumbai-based furniture manufacturer with ₹95 lakh annual turnover
Calculation:
- Applicable rate: 1% (regular state)
- Annual tax: ₹95,00,000 × 1% = ₹95,000
- Quarterly tax: ₹95,000 ÷ 4 = ₹23,750

Savings: Compared to regular GST (18% on profit margin), this business saves approximately ₹2.5 lakh annually.
Case Study 2: Restaurant in Sikkim
Scenario: Gangtok restaurant with ₹60 lakh annual food sales
Calculation:
- Applicable rate: 2.5% (special category state)
- Annual tax: ₹60,00,000 × 2.5% = ₹1,50,000

Module G: Interactive FAQ
What is the maximum turnover limit for composition scheme in 2024?
As of 2024, the turnover limits are:
- ₹1.5 crore for most states (increased from ₹1 crore in 2019)
- ₹75 lakh for special category states (North-Eastern states, Himachal Pradesh, Uttarakhand)
- ₹50 lakh for service providers (special category)
These limits are reviewed annually. Check the official GST portal for updates.
Can I switch from regular GST to composition scheme mid-year?
Yes, you can opt into the composition scheme at any time during the financial year by filing Form CMP-02. However:
- You must file a statement in Form ITC-03 within 60 days for reversing input tax credit
- The switch takes effect from the beginning of the next quarter
- You cannot switch back to regular scheme for at least one year
Example: If you apply in May, the composition scheme will start from 1st July.
What happens if I exceed the turnover limit?
If your turnover exceeds the limit during a financial year:
- You must opt out of the composition scheme immediately
- File Form CMP-04 to withdraw from the scheme
- Register as a regular taxpayer and file GSTR-3B monthly
- Pay tax at regular rates from the day you exceeded the limit
Failure to do so may attract penalties under Section 122 of the CGST Act.
Can I sell through e-commerce platforms under composition scheme?
Generally no. Most e-commerce platforms (Amazon, Flipkart, etc.) require sellers to have regular GST registration because:
- Platforms collect TCS (Tax Collected at Source) at 1%
- Composition taxpayers cannot collect GST from customers
- Inter-state sales are not permitted under composition scheme
Exception: Some platforms allow composition scheme sellers for intra-state sales if they meet specific criteria. Check with the platform’s seller policies.
How do I calculate tax if I have multiple business verticals?
The composition scheme applies to your aggregate turnover across all business verticals with the same PAN. You have two options:
- Single registration: Combine all turnover and pay tax at the highest applicable rate among your businesses
- Separate registrations: If verticals are distinct (different locations/activities), you can have separate registrations:
- Each registration must independently qualify for composition scheme
- Turnover limits apply separately to each registration
- Requires separate books of accounts for each
Consult a GST practitioner to determine the optimal structure for your specific situation.
What records must I maintain under the composition scheme?
While simplified, you must maintain these records for at least 6 years:
- Bill of Supply: For all sales (instead of tax invoices)
- Purchase Invoices: Even though ITC isn’t available
- Quarterly Sales Summary: State-wise breakdown
- Payment Challans: Proof of tax payments (CMP-08)
- Stock Records: Opening/closing stock details
- Bank Statements: To verify reported turnover
Unlike regular GST, you don’t need to maintain:
- GSTR-1/3B reconciliation
- Input tax credit ledgers
- E-way bill records (unless transporting goods)
Is the composition scheme beneficial for service providers?
The composition scheme for service providers (introduced in 2019) has specific pros and cons:
Advantages:
- Flat 6% tax rate (vs 18% under regular GST)
- Quarterly returns instead of monthly
- No complex ITC calculations
- Ideal for freelancers/consultants with turnover ≤ ₹50 lakh
Disadvantages:
- Cannot provide services through e-commerce platforms
- No input tax credit on business expenses
- Cannot issue tax invoices (may be problematic for B2B clients)
- Inter-state service provision is not allowed
Best for: Local service providers (architects, lawyers, accountants) serving individual clients rather than businesses.
