A small business in Mumbai—a proprietorship, a partnership, a small trading concern or a service provider—faces a GST framework that is simple in outline but unforgiving in detail. The registration threshold for a service provider is ₹20 lakh; for a supplier of goods, it is ₹40 lakh (₹20 lakh in the special category states). Aggregate turnover is PAN-based and all-India. The composition scheme is available for goods suppliers and restaurants up to ₹1.5 crore, and for service providers up to ₹50 lakh at a 6% rate, but it carries restrictions on input tax credit, inter-state supply and e-commerce.
The Registration Decision
The threshold is not the only registration trigger. A business making inter-state supplies, supplying through an e-commerce operator, or liable under reverse charge must register regardless of turnover. A voluntary registration can be commercially rational where the business incurs significant input tax on rent, equipment or professional services and has taxable output. The decision should be modelled, not defaulted.
The Composition Trade-Off
The composition scheme reduces the compliance burden—quarterly returns, no ITC, no tax invoice—but it restricts the business’s ability to supply inter-state and to pass on credit. A small manufacturer or trader with B2B customers who need ITC may find that the composition scheme costs more in lost customer credit than it saves in compliance. A restaurant or a small service provider with B2C customers may find the composition route simpler. The election is annual and requires Form CMP-02.
The Compliance Discipline
The small business should maintain a GST-compliant invoice series, a purchase register with GSTIN verification, a monthly GSTR-1/GSTR-3B reconciliation, and a reversal register for Section 17(5) and Rule 42/43 items. The GSTR-2B reconciliation is the single most effective defence against ITC notices. Records must be retained for 72 months.
What the Consultant Does
The consultant assists with the registration decision, the composition election, the monthly return cycle, the ITC reconciliation, the notice response and the annual return. The value is not in the form-filing alone; it is in the architecture that prevents a scrutiny notice and the documentation that defends one.
