Property transactions detected years later – Most common Mumbai trigger. Stamp duty data, registrar records, buyer/seller TDS (Section 194-IA) flag unreported capital gains or unexplained source. Mumbai property values amplify additions. Patron defends with source documentation and Section 54/54F analysis.

Foreign remittances and CRS data – Information from foreign authorities: undisclosed accounts, investments, income. BKC MNC executives, Nariman Point professionals, NRIs particularly affected. Patron handles with DTAA and Schedule FA expertise.

AIS/SFT mismatch from prior years – Retrospective AIS data: bank deposits, mutual funds, shares not reflected in old ITR. Patron reconciles historical AIS for Mumbai taxpayers.

Investigation wing information – Accommodation entry operators, shell companies, hawala records. Patron defends against investigation-triggered reassessments.

Demonetisation cash deposits – November-December 2016 high cash deposits without matching income. Department continues reopening these. Patron defends with cash flow analysis.

Transfer pricing revisits – BKC MNC subsidiaries: prior years reopened based on new TP data or foreign jurisdiction information. Patron represents in TP-based reassessments. For Tax Planning, see our page.

“The Department reopened my 4-year-old assessment for a Mumbai property purchase, alleging Rs 30 lakh income escaped. Patron responded to the 148A show-cause with complete source documentation and a Bombay HC judgment on change of opinion. The AO dropped the proceedings at 148A itself – no reassessment happened.”

The 148A show-cause response is the single most important document in reassessment. A strong response can prevent the reassessment entirely – saving years of litigation and potentially lakhs in additions. The response deadline is strict (typically 7-30 days). Missing it means the AO proceeds without your input. Every day of delay weakens your defence.
