Section 186 - Mode of undertaking transactions
Simple decode Section 186 has three independent aggregation tests. Splitting a receipt across invoices, branches or days does not necessarily solve the problem if it remains one transaction or one event or occasion. The test is on receipt, not merely on invoicing or accounting entry.

Current law and effective date
Section 186 is controlled against the consolidated Income-tax Act, 2025 as amended by the Finance Act, 2026. The Act and Income-tax Rules, 2026 operate from 1 April 2026; earlier years and saved proceedings require the repeal-and-savings framework rather than automatic migration.

Old-law bridge
section 269ST
The old-law bridge is navigational, not automatic precedent transfer. Match the 1961 Act wording, saved proceedings, current 2025 Act text and effective date before importing an older interpretation.
Finance Act 2026 / current-law note
No section-specific Finance Act, 2026 textual substitution is separately flagged for section 186; the consolidated post-Finance-Act-2026 text remains the controlling version and must be used instead of pre-1 April 2026 extracts.
Professional alert
Test person-per-day, single-transaction and event/occasion independently. Link deposits and final settlement to the same commercial event. Build POS and ERP blocks for cash receipts at or near ₹2 lakh.

Worked application
A wedding venue receives ₹1.25 lakh cash as booking advance and ₹90,000 cash later for the same wedding. Even on different days, the event-or-occasion test aggregates the receipts to ₹2.15 lakh.
Evidence / compliance checklist
- Test person-per-day, single-transaction and event/occasion independently (section 186 evidence control 1).
- Link deposits and final settlement to the same commercial event (section 186 evidence control 2).
- Build POS and ERP blocks for cash receipts at or near ₹2 lakh (section 186 evidence control 3).
Common mistake
A common section 186 error is to apply the old-law label or headline rate without rebuilding the current statutory conditions. For “Mode of undertaking transactions”, the safer control is to test the exact taxpayer/transaction facts, the operative tax year, every linked Rule/Form and the Finance Act 2026 consolidated wording. Test person-per-day, single-transaction and event/occasion independently. Link deposits and final settlement to the same commercial event. Build POS and ERP blocks for cash receipts at or near ₹2 lakh.
Recommended approach
For section 186, start with the legal trigger in “Mode of undertaking transactions”, document the evidence for that trigger, then run the computation or procedural step against the current text. As a cross-check, verify this provision-specific checkpoint: Section 186 prohibits receipt of Rs 2,00,000 or more in the specified person/day, single-transaction or event/occasion aggregations, subject to statutory exceptions and permitted modes.

FAQs
Does an old Income-tax Act, 1961 case automatically decide section 186?
No. The old-law bridge helps research, but transferability depends on materially matching language, transition rules and any Finance Act 2026 change.
