Know your GST audit exposure before the officer does.
Upload your Tally exports and GSTR-2B. TaxCorp quantifies every ITC and RCM exposure — with interest, a per-supplier breakdown, and a readiness note grounded in the official CBIC Model GST Audit Manual. The number you walk in with is one you can defend.
The questions a GST auditor will ask
A Section 65 audit comes down to a handful of recurring demands. TaxCorp answers each one against your own books — before the notice lands.
Five audit-grade checks
Each check runs on your own data, flags the exact exposure with the statutory basis, and excludes the items the rule doesn't apply to — so the number is one you can defend before an officer.
180-Day ITC Reversal
Upload your purchase register or Tally bills-outstanding (ageing) export. We flag invoices unpaid beyond 180 days where ITC was availed — reversing only the proportionate unpaid portion, computing interest u/s 50, and excluding RCM & Schedule-I supplies.
Open 180-Day Check →GSTR-2B vs 3B Reconciliation
Upload your portal GSTR-2B JSON and purchase register. We match invoice-by-invoice (absorbing invoice-number format differences), and quantify ITC claimed but not backed by 2B — the top departmental demand — plus what's available but unclaimed. Upload several months' 2B together and credit appearing in a neighbouring month (late supplier filing) is netted as a timing difference, not counted as a demand.
Open 2B vs 3B →Blocked Credits
We scan expense heads, narration and HSN/SAC to flag ITC on blocked supplies — motor vehicles, food & beverage, club, CSR, works contract, construction, gifts — with the specific clause. Statutory exceptions are surfaced for your confirmation.
Open 17(5) Check →RCM Completeness
We scan expenses for reverse-charge supplies — GTA freight, advocate fees, director's services, sponsorship, security, renting of vehicle, import of service — quantify the RCM you were liable to self-assess, net it against what you booked and declared in GSTR-3B, and flag the lines where nothing was paid.
Open RCM Check →Common-Credit Reversal
Used inputs and capital goods commonly for taxable and exempt supplies? We run the statutory Rule 42 (inputs) and Rule 43 (capital goods) worksheets on your turnover split and common ITC — computing D1, the deemed 5% D2 and the per-period capital reversal Te — then net it against what you reversed in GSTR-3B, with interest.
Open 42/43 Check →Not sure where to begin? Ask the audit assistant.
Get plain-language answers to any Section 65 question — what the officer will ask, which records to keep, how to defend an ITC or RCM position — grounded in the CBIC Model GST Audit Manual, the ICAI Handbook on Finalisation of Accounts and relevant case law. Switch to "experienced" mode for a precise, section-cited answer.
Then work the interactive audit-readiness checklist — 40+ points across notice, records, reconciliations, ITC, RCM, valuation and documentation, each with its statutory basis — and export it as your prep plan.
Open Audit Q&A & ChecklistGrounded in the playbook departmental officers actually use
The CBIC Model All India GST Audit Manual 2023 is the verification framework officers follow during a Section 65 audit. TaxCorp reads it directly and verbatim — not a paraphrase — so your readiness note mirrors how each issue is examined on the ground.
For reverse charge, your note is built around Annexure 9 — "Levy of tax on Reverse Charge Mechanism", the manual's own RCM checklist (Section 9(4) supplies, departmental Q&A and the leading RCM case law), so you address every point before it's raised.
- Verbatim statutory text and notification references — nothing invented.
- Relevant case law surfaced by TaxCorp AI alongside the manual.
- A ready-to-file readiness note (PDF) and an exceptions workbook (Excel).
Built for the audit, not just a flag
Every check shares the same audit-grade plumbing — the difference between a spreadsheet guess and a defensible number.
Interest u/s 50
Interest computed per line with the Rule 88B utilisation guard — not just a headline reversal.
Per-supplier exposure
See which vendors drive your risk — aggregated by GSTIN, ranked by exposure.
False-positives excluded
RCM, imports, Schedule-I, forward charge, 17(5) exceptions and cross-month timing differences are carved out so the figure holds up.

A case-backed note grounded in the CBIC manual, plus a line-by-line exceptions workbook.

Questions, answered
What do I need to upload?
Will it raise false demands on items the rule doesn't cover?
Is the legal basis citable in front of an officer?
Does this replace my professional judgement?
