Factories here need careful handling of capital-goods credit, job-work movements (section 143) and e-way bills for every dispatch.

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.
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.
How do we keep input credit safe?
Credit is allowed only if the supplier has reported the invoice and it appears in your GSTR-2B (section 16(2)(aa)). We use the Invoice Management System to accept, reject or keep supplier invoices pending each month, and follow up unreported invoices before the return, which avoids most mismatch notices.
