India's financial capital and largest commercial city, home to BSE, NSE, India's biggest port at JNPT, and a thriving startup ecosystem. Small businesses in Mumbai, Maharashtra — traders in Nariman Point, manufacturers near Bandra Kurla Complex (BKC), small restaurants and service providers across the city — can significantly simplify their GST compliance through the Composition Scheme. Instead of monthly returns and complex invoice-level tracking, composition dealers pay a flat rate on turnover and file quarterly. TaxAMC's CA team helps Mumbai businesses evaluate, register, and manage GST composition compliance.

1. What is the GST Composition Scheme?
The composition scheme under Section 10 of the CGST Act allows small taxpayers in Mumbai to pay GST at a fixed percentage of total turnover. Key features:
- Flat rate tax on turnover — no transaction-level GST calculation needed
- Quarterly CMP-08 statement instead of monthly GSTR-3B
- Annual GSTR-4 instead of annual GSTR-9
- Cannot collect GST from customers — tax is borne by the dealer
- Cannot claim Input Tax Credit (ITC) on purchases
2. Eligibility for Mumbai Businesses
| Business Type | Turnover Limit |
|---|---|
| Manufacturers and traders (goods) | Up to ₹1.5 crore/year |
| Restaurants not serving alcohol | Up to ₹1.5 crore/year |
| Service providers (CGST Rule 7) | Up to ₹50 lakh/year |
Not eligible: Businesses making inter-state supplies, e-commerce sellers (Amazon, Flipkart, Meesho), manufacturers of tobacco, pan masala, and ice cream.
Mumbai's diverse economy — spanning BFSI, media, textiles, logistics, and retail — means every business category has distinct GST implications. For Mumbai's businesses in Financial services and banking (BSE, NSE) and Import-export via JNPT, the composition scheme may be particularly beneficial for smaller operators focused on local customers.
3. Tax Rates Under Composition Scheme
| Business Category | CGST | SGST | Total GST |
|---|---|---|---|
| Manufacturers and traders (goods) | 0.5% | 0.5% | 1% of turnover |
| Restaurants (not serving alcohol) | 2.5% | 2.5% | 5% of turnover |
| Service providers (Rule 7) | 3% | 3% | 6% of turnover |
Note: These rates apply on total turnover — not just on profit or value addition. Tax cannot be charged separately on customer invoices.
4. Filing Requirements for Mumbai Composition Dealers
| Return | Frequency | Due Date |
|---|---|---|
| CMP-08 (tax statement) | Quarterly | 18th of month after quarter end |
| GSTR-4 (annual return) | Annual | 30th April of next financial year |
This is significantly simpler than regular GST — which requires GSTR-1 monthly and GSTR-3B monthly. Mumbai composition dealers save substantial compliance time and cost.
5. Restrictions and Disadvantages
- No ITC on purchases: Cannot claim input tax credit — biggest disadvantage for businesses with high raw material or service costs
- No inter-state supply: All sales must be within Maharashtra only
- Cannot issue tax invoice: Issue "Bill of Supply" instead — your customers cannot claim ITC from purchases made from you
- Must display: "Composition Taxable Person, not eligible to collect tax on supplies" on all business premises and invoices
- Tax on total turnover: Pay tax even if margins are thin or losses occur
6. Composition vs Regular GST for Mumbai Businesses
Composition is better for: Retail traders, small restaurants, and service providers in Mumbai whose customers are mostly end consumers (not GST-registered businesses), and who have low input costs relative to turnover.
Regular GST is better for: Businesses in Mumbai whose customers are GST-registered (B2B) and need to claim ITC from your invoices, those with high input costs (raw materials, packaging, logistics), and those wanting to make inter-state supplies.
