What is CA PRO Toolkit?
CA PRO Toolkit is a free Chrome extension for Chartered Accountancy firms in India. It reads an audit working paper, identifies the audit topic, and maps every procedure to the Standards on Auditing, relevant Ind AS and Companies Act 2013 sections. The same signed-in session also reconciles GST, reviews TDS, tracks notices and cases, runs audit engagements, and keeps the firm's tasks, calendar and reminders in one place.
- Who it is for
- Audit teams, tax and compliance staff, and firm administrators in Indian CA practices, from a single practitioner to a multi-member firm.
- What it does
- AI audit review with standards mapping, Standard Guidance lookups, GST reconciliation (Purchase Register versus GSTR-2B, ITC claimed versus GSTR-3B, GSTR-1 turnover versus GSTR-3B, and ITC claimed versus the credit the Electronic Credit Ledger received), TDS health checks (deductions, ITNS 281 challans, statements, PAN, imported 26AS), notices and cases, audit engagements, a firm task board and filing dashboard, a compliance calendar with reminders, and daily and weekly work summaries.
- What it costs
- Nothing. It is free to install and use from the Chrome Web Store. You sign in with Google.
- What it deliberately does not do
- It never files or submits anything to a government portal, and never issues a professional opinion on its own. It can download your own returns and ledgers from the GST portal, in your own signed-in session, when you ask it to. Dates, amounts and conclusions stay unconfirmed until a person confirms them.

The tools behind those steps
One signed-in session powers every tool below. Each card says which product it runs in.
GSTR Downloader
Download a whole year of GSTR-1, 2A, 2B, 3B, 9 and 9C, plus the Credit and Cash Ledgers, from the GST portal in one run — in your own signed-in session. It never files anything.
Extension
GST Reconciliation
Three checks on one period: Purchase Register vs GSTR-2B, the credit you claimed vs the credit review supports, GSTR-1 turnover vs GSTR-3B, and claimed ITC vs the credit your Electronic Credit Ledger actually received. Exact to the paise; every ambiguous case waits for review. Clear settled cases in bulk and chase suppliers on what is missing.

Serious about your clients' data
CA PRO Toolkit is a review and organisation tool. It never files to a government portal on its own.
Secure sign-in
Google Sign-In with token-based sessions. Firm roles and permissions are enforced on the server.
Local-first documents
File text is read on your device first. Source files are not retained after processing.
Consent-gated AI & OCR
Reading a document or image online needs your explicit consent every time it happens. Model-assisted review is covered by the Terms you accept when you sign in, and the Windows app carries a switch that turns it off, so nothing you type leaves your device.
No portal filing
The product never files or submits anything to a portal, and never claims a professional opinion on its own. It downloads your own returns from the GST portal only when you ask it to.
See it, and erase it
The Windows app lists exactly what it holds on your PC and for how long, and you can request erasure of your account data.
Human review gates
Dates, amounts and conclusions stay unconfirmed until a person confirms them.
Your data stays yours
We do not sell your data, and we do not track you across other websites.

Is CA PRO Toolkit free?
Yes. The extension is free to install from the Chrome Web Store. Sign in with Google to get started.
Does it file returns to the GST or Income Tax portal?
No. It helps you review and organise work, and it never files or submits anything to a portal, or produces a final professional opinion on its own. It can download your own returns and ledgers from the GST portal, in your own signed-in session, when you ask it to.
Is my clients' data safe?
Documents are read on your device first, source files are not retained, and any AI or online text reading needs your explicit consent. We do not sell your data.
Which auditing standards does the AI review cover?
It maps procedures to the Standards on Auditing (SA series), relevant Ind AS, and Companies Act 2013 sections, and can generate guidance for any code you look up.
Can my whole team use it together?
Yes. Create a firm or join one with an invite code. Members share the same tasks, clients and reviews, with roles for owners, admins and members.
Do I need an account?
