What is GST compliance?
GST is charged on supplies of goods and services. Once registered, a business files monthly or quarterly returns, reconciles its input tax credit with suppliers' data, and files an annual return.
When must a business in Avadi IAF register?
A supplier of goods in Tamil Nadu must register once aggregate turnover crosses ₹40 lakh in a financial year, and a supplier of services once it crosses ₹20 lakh (section 22 of the CGST Act, 2017). Some must register regardless of turnover, including inter-state suppliers of goods and persons liable to pay tax under reverse charge (section 24). The composition scheme is available up to ₹1.5 crore of turnover for goods (section 10).
Which returns are filed, and when?
Regular taxpayers file GSTR-1 for outward supplies and GSTR-3B for tax payment — monthly, or quarterly under the QRMP scheme if turnover is up to ₹5 crore. The annual return GSTR-9 is optional up to ₹2 crore of turnover, and the self-certified reconciliation GSTR-9C is needed above ₹5 crore. E-invoicing applies above ₹5 crore of turnover, and an e-way bill is needed to move goods worth more than ₹50,000.
