Received a GST or income tax notice? Start here.

A notice is a request for information or an explanation, not a verdict. A careful, on-time reply resolves most of them.

Six steps

  • Read it fully. Note the section, the period, the amount and exactly what is being asked.
  • Find the reply deadline and mark it. Missing it can turn a simple query into an order.
  • Check whether the notice is genuine by viewing it on the official portal, where real notices appear in your account.
  • Collect the records the notice refers to: invoices, returns, bank statements, challans and earlier correspondence.
  • Compare your returns with the department’s records to see where the difference arises.
  • Reply through the portal with a clear, factual answer and supporting documents, and keep the acknowledgement.

Common causes

Many notices come from mismatches: tax credit claimed that does not appear in supplier returns, income or tax deducted that differs from the department’s statements, or returns not filed. Some are routine reminders. Others ask for a detailed explanation.

When to get help

If the amount is large, the notice cites a section you do not understand, or the deadline is close, share it with a professional early. A well-drafted reply matters more than a quick one, and some notices allow you to ask for more time.

Do not ignore it

An unanswered notice can lead to an assessment based on the department’s own view, with interest and penalty added. Replying on time is nearly always cheaper.

Quick answers
