Responding to a GST Show Cause Notice: Timelines and Best Practices

This article is general information only, not legal advice, and not solicitation of work. It should not be relied upon as a substitute for advice on your specific facts.

What Triggers a GST Show Cause Notice

A show cause notice under the GST law is typically issued where the department believes there has been short payment of tax, wrongful availment or utilisation of input tax credit, or a mismatch between returns filed and data available with the department, such as GSTR-2A or e-way bill records. It is the department’s formal way of stating its case and calling on the taxpayer to respond before any demand is confirmed.

Reading the Notice Correctly

The notice will specify the provision under which it is issued, commonly Section 73 for cases without allegation of fraud, or Section 74 where fraud, wilful misstatement, or suppression of facts is alleged, since this materially affects both the limitation period and the applicable penalty. It is important to identify precisely which provision is invoked before drafting a response, since the standard of proof and consequences differ significantly between the two.

Timelines for Response

A notice typically prescribes a period, often thirty days, within which a reply must be filed, and taxpayers should not let this lapse even if they intend to contest the notice on jurisdictional or procedural grounds, since silence is generally treated as an admission and can result in an ex parte order confirming the demand.

Structuring an Effective Reply

A strong reply addresses each allegation specifically rather than generally, supports factual claims with reconciled figures and documentary evidence, such as invoices, e-way bills, and bank statements, and explicitly engages with the legal provision invoked. Where the underlying liability is genuinely owed, paying the tax along with applicable interest before adjudication can meaningfully reduce the eventual penalty exposure.
