A GST notice is an official communication from the Goods and Services Tax (GST) Department to a registered taxpayer requesting clarification, rectification, or additional information related to GST returns, payments, or compliance. Notices may arise due to mismatch of input tax credit (ITC), non-filing of returns, under-reporting of tax liability, or random audits. Responding accurately and on time is crucial to avoid penalties, interest, or legal actions. The process involves carefully reviewing the notice, understanding the specific queries, collecting relevant documents such as GST returns, invoices, payment challans, and reconciliation statements, and preparing a formal reply. The response must address each point raised by the department, provide evidence, and be submitted electronically through the GST portal or physically if required. Professional assistance is recommended to ensure correct interpretation of the notice, accurate documentation, and compliance with statutory timelines. Timely and precise responses help in resolving disputes, avoiding penalties, maintaining compliance, and safeguarding the taxpayer’s credibility under GST law.
