Response window: 7-30 days typical.
Response strategy: documentary refutation + legal position + specific exhibits.

What to watch.

Not acknowledging notice via portal (deadlines keep running).
Missing response deadline (AO proceeds with specific adverse presumptions).
Not engaging CA (DIY response often substandard).
Not preserving records (specific documentary refutation becomes difficult).
Not understanding risk cascade (143(2) can lead to 148, 148A to 148, specific appeal implications).
Not raising specific legal grounds (jurisdictional / procedural / substantive).
Not considering specific appeal path (CIT(A) / ITAT / High Court / writ) at outset.
Not managing Section 270A penalty defence (classification 50% vs 200% matters materially).

FAQ

Common questions, answered.

How to respond to Income Tax notice India?

First identify notice type (143(1) / 143(2) / 148 / 148A / 139(9) / 142(1) / 245 / 154 / 156). Each has distinct response window + consequences. Acknowledge on portal + preserve records + engage CA within 24-48 hours + respond within specified deadline (typically 7-30 days). Default: no response = AO proceeds with specific adverse presumptions. BQP urgent response team.

What's the typical response deadline for Income Tax notice?

Varies by notice type. Section 143(1) demand: 30 days. Section 143(2) scrutiny first response: 15-30 days + 6-month assessment window. Section 148A(b): 7-30 days. Section 148: 30 days to file return. Section 139(9) defective: 15 days. Section 142(1): 15-30 days. Section 245: 30 days. Section 154: 30 days. Section 156: 30 days to pay / 15 days to object.

Can Section 148A show-cause be quashed before Section 148 reassessment?

Yes - Section 148A(b) response is quashing opportunity. Well-drafted response can achieve Section 148A(d) order dropping the proceeding (no Section 148 formal notice). For procedurally defective 148A: writ in High Court can quash (several High Court rulings have struck down defective 148A). Specific legal grounds + specific case law critical.

What happens if I don't respond to Income Tax notice?

AO proceeds with only AO's version considered. Specific adverse presumptions. Section 148 reassessment if 148A unresponded. Section 143(3) ex-parte scrutiny order if 143(2) unresponded.
