E-Invoicing under GST is a system where B2B invoices are electronically authenticated by the Invoice Registration Portal (IRP) before being issued to customers. As of 2025, it is applicable to GST-registered businesses with an annual turnover of ₹5 crore or more (subject to government updates). Under this system, invoices must follow a prescribed format and include mandatory details such as GSTIN, invoice number, and HSN codes. Once validated, the IRP generates an Invoice Reference Number (IRN) and QR code. E-invoicing helps reduce tax evasion, ensures real-time reporting, and simplifies GST return filing and e-way bill generation.

Small businesses often make common GST filing mistakes that can lead to notices, penalties, or compliance issues. Key mistakes include incorrect or mismatched invoice details, missing ITC claims, or claiming ineligible ITC without proper documentation. Many businesses also forget to file NIL returns, delay monthly or quarterly filings, or use wrong HSN/SAC codes. Not reconciling GSTR-2B with purchase records and failing to maintain accurate books further cause discrepancies. Businesses should regularly update records, verify invoices, reconcile data, and file returns on time to ensure smooth GST compliance and avoid unnecessary financial or legal complications.

A GST refund is the process of reclaiming excess tax paid under India’s Goods and Services Tax (GST) system. Businesses can apply for refunds in cases like exports, inverted duty structures, supplies to SEZ units, excess tax payment, or balance in the electronic cash ledger. Filing refunds ensures smooth cash flow and compliance. Taxpayers must file Form GST RFD-01 online within two years from the relevant date. In 2025, GST introduced an invoice-based refund system for better transparency and accuracy, requiring all due returns to be filed before submitting the refund claim.

E-Invoicing and E-Way Bill under GST ensure compliance, transparency, and traceability in business transactions and goods movement. E-invoicing is mandatory for businesses with turnover above ₹5 crore, requiring invoices to be authenticated through the Invoice Registration Portal (IRP), which generates an IRN and QR code. Exemptions include SEZ units, banks, NBFCs, and transport services. E-invoices must be cancelled within 24 hours, else rectified via credit/debit notes. Similarly, E-Way Bills are required for transporting goods valued over ₹50,000, capturing consignment and transport details. Non-compliance leads to penalties, ITC denial, and detention of goods, making timely compliance critical.
