Advance Tax and the 234B/234C Interest Traps
234C penalises missing the quarterly instalment schedule even if you pay in full by year-end. 234B penalises falling short of 90% by 31 March even if every instalment was on time. They test different things, run on different clocks, and can both bite the same taxpayer independently.

Angel Tax Is Dead — What CAs Still Need to Check for Legacy Assessments
Section 56(2)(viib) was abolished for every share issuance from 1 April 2025. But the provision was in force for over a decade, and open assessments for AY 2013-14 through AY 2025-26 still need the old Rule 11UA safe-harbour and DPIIT exemption tests applied correctly.

F&O Turnover for Tax Audit: The 8th vs 10th Edition ICAI Method, Explained
The 2025 ICAI Guidance Note reinstated option premium into the F&O turnover formula — reversing what the 8th edition had removed for AY 2022-23 onward. Using the older formula today understates turnover, and can wrongly clear a client of a tax audit that's actually required.

GST and TDS Late Fee & Interest, Side by Side
Both regimes charge interest and a per-day late fee, but the mechanics don't match. GST interest runs on the cash-ledger tax only; TDS runs two separate interest meters — one for late deduction, one for late deposit — on month-or-part, not per-day.

Leave Encashment Tax Exemption: The ₹25 Lakh Lifetime Cap, Explained
Section 10(10AA) exempts leave encashment on the least of four separate legs — and the ₹25 lakh limit is a lifetime cap across every employer a person has ever worked for, not a per-employer or per-encashment allowance.

Net Worth Under Section 2(57): One Definition, Different Thresholds Downstream
The Companies Act's Section 2(57) net-worth definition feeds Ind AS applicability, CSR triggers, and XBRL filing — but each downstream rule uses a different threshold, and XBRL isn't even net-worth-gated. Getting the base computation right isn't the same as applying it correctly.

Section 40(b) caps working-partner remuneration on a two-slab book-profit test, revised by the Finance Act 2024. But the remuneration limit is only one of three checks — partner interest has its own 12% cap, and Section 194T adds a new TDS obligation firms often miss.

Schedule II depreciates by individual-asset useful life. The Income Tax Act depreciates by pooled blocks with a 180-day half-rate cliff. Same asset, same year, two genuinely different figures — and that gap is exactly what feeds the AS 22 / Ind AS 12 deferred tax line.
