Which AI Subscription Should a CA Firm Actually Buy? A Procurement Guide
Not which model is best — how many seats, which tier, what it costs a firm of five or fifty, whether GST input credit is available on a foreign AI subscription, and what has to be in the contract before client data is involved.

Can ChatGPT Do My Audit? Where the Useful Part Ends

Open Source vs Self-Hosted vs API Key: Where Your Client's Data Actually Goes
Three phrases Indian CA firms use interchangeably that mean completely different things. Open weights are not the same as self-hosted, and a paid API key is not the same as a ChatGPT subscription — the difference decides your DPDP and confidentiality position.

TDS Verification in FY 2026-27: What to Automate After the Section Renumbering
The first audit year under the Income-tax Act 2025 means TDS data carries two numbering schemes at once — old 194-series labels in the books, new Sec 393 payment codes in TRACES. The three-way reconciliation, what breaks, and what should be computed rather than eyeballed.

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.

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.
