The problem in CA and tax firms
Tax practices and filing platforms run on deadlines: individual ITR filing, usually due 31 July, monthly GST returns, quarterly advance tax and the TDS calendar. The bottleneck is rarely the filing itself — it is chasing clients for Form 16, AIS checks, bank statements and invoices. Staff spend July on the phone instead of preparing returns. Chartered accountants also face ICAI rules restricting solicitation, which shape who can be called.
What the AI employee actually does
- 01Run campaigns in June and July asking salaried clients for Form 16, rent receipts, investment proofs and capital-gains statements
- 02Remind GST clients before each return due date to share sales and purchase invoices
- 03Send the document checklist and upload link over WhatsApp during the call
- 04Call new enquiries on tax-filing platforms within 30 seconds and book a slot with a tax expert
- 05Run advance-tax reminder campaigns before each quarterly instalment date
Businesses measure this on one number: documents received before deadline and returns filed on time.

A sample CA and tax firms call
In July, a Chennai CA firm's agent calls an existing salaried client whose Form 16 is still missing, ahead of return filing. · Runs in Tamil with English words; shown here in English.
- Outpero AIVanakkam, this is the AI assistant of Venkatesh and Associates, Chennai. Am I speaking with Karthik? We are preparing your income tax return and still need a few documents from you. Do you have a minute?
- CallerYes, tell me. I changed jobs last year, will that be a problem?
- Outpero AIYour CA, Mr. Venkatesh, will handle how the return is prepared. From my side, I only need the documents. Since you changed jobs, we should have two Form 16s, one from each employer. Do you have both?
- CallerI have the new one. The old company has not sent it yet.
- Outpero AINoted. Could you please ask the old employer's HR for it and send it on WhatsApp when it arrives? We also need your rent receipts and any investment proofs, such as PPF or an insurance premium receipt.
- CallerI have rent receipts. Tell me honestly, how much refund will I get this time?
- Outpero AII cannot calculate that, and I do not want to guess. Mr. Venkatesh will work it out after he has all the documents. Which of the documents can you send today?
- CallerForm 16 from the new company and the rent receipts. I will send them tonight.
- Outpero AIThank you. I am sending the checklist and the secure upload link on WhatsApp now. We never ask for your income tax portal password or any OTP on a call. May I call you again on Thursday for the old Form 16?
- CallerYes, call on Thursday evening.
Status recorded per document: new-employer Form 16 and rent receipts promised tonight, old-employer Form 16 pending, investment proofs requested. Checklist and upload link sent on WhatsApp, follow-up call set for Thursday evening, client's refund question passed to the CA unanswered.

Where the leads come from
Where CA and tax firms get their phone leads
- →Your existing client list, uploaded as a CSV before each filing season
- →Google search and Google Ads leads for ITR filing, GST registration and return filing
- →Meta ads in the tax-filing season, landing on a short enquiry form
- →Website forms and WhatsApp click-to-chat messages
- →Referrals from existing clients, employers and other professionals
- →JustDial and Google Business Profile enquiries
Leads reach the agent by webhook, Zapier or Make, a CRM workflow, a CSV upload, or by parsing the alert email a portal sends — whichever your source supports.
Rules that shape the call
What CA and tax firms need to get right
| Rule or norm | What it means for the agent |
|---|---|
| Chartered Accountants Act, 1949 and the ICAI Code of Ethics | The institute's rules restrict solicitation by practising chartered accountants. Calls therefore go to existing clients and people who enquired, not cold lists. |
| Income-tax Act, 1961 filing calendar | Return and advance-tax due dates drive the call schedule. The agent states the date your firm gives it and does not interpret extensions or penalties. |
| No tax advice from the agent | The agent collects documents and books the CA. Refund estimates, regime choice and deductions are left to the CA. |
| Digital Personal Data Protection Act, 2023 | PAN, income and bank details move through your secure upload link, not over a voice call, and the agent never asks for portal passwords or OTPs. |
General information, not legal advice. Calls also run under TRAI’s rules on DLT-registered lines and the DND registry.

CA & Tax Services — questions people ask
Can an AI voice agent work for CA and tax firms?
+
Yes. Outpero's AI voice agent handles CA and tax firms calls end to end — running document-collection and deadline-reminder campaigns to existing clients ahead of every filing date. It works 24 hours a day in Hindi, Telugu, Tamil, Marathi, Kannada, Malayalam and English, switching to English the moment the caller does.
What does an AI voice agent do for CA and tax firms?
+
For CA and tax firms, an Outpero AI employee will run campaigns in June and July asking salaried clients for Form 16, rent receipts, investment proofs and capital-gains statements; remind GST clients before each return due date to share sales and purchase invoices; send the document checklist and upload link over WhatsApp during the call; call new enquiries on tax-filing platforms within 30 seconds and book a slot with a tax expert. Every call is recorded, transcribed and summarised automatically.
How much does an AI voice agent cost for CA and tax firms in India?
+
Outpero has no setup fee and no monthly base fee — you pay only for connected talk time, from ₹5 per minute (1 credit = ₹1, credits never expire), plus ₹649/month for a dedicated calling number. A full-time telecaller doing the same job costs around ₹18,000 a month, works one shift and handles one call at a time. Prices exclude 18% GST.
How fast does it respond to a new CA and tax firms enquiry?
+
Under 30 seconds from the enquiry landing. That matters here because tax practices and filing platforms run on deadlines: individual ITR filing, usually due 31 July, monthly GST returns, quarterly advance tax and the TDS calendar. The bottleneck is rarely the filing itself — it is chasing clients for Form 16, AIS checks, bank statements and invoices. Staff spend July on the phone instead of preparing returns. Chartered accountants also face ICAI rules restricting solicitation, which shape who can be called.
Can CA firms use outbound calls under ICAI rules?
+
ICAI's Code of Ethics restricts chartered accountants from soliciting clients or professional work. Calling your existing clients about their own filings is service, not solicitation, and that is where most practices use the agent. Cold-calling prospects is a different matter for a CA firm. Tax-filing platforms that are not CA firms work under different rules, but should still call only people who enquired.
Does the agent give tax advice?
+
No. It does not decide which tax regime suits a client, whether a deduction applies or how to treat capital gains. It collects documents and information, confirms deadlines and books time with the CA or tax expert. If a client asks a technical question, the agent notes it so the preparer addresses it while filing, which also keeps your advice documented in one place.
How does it know what each client still owes you?
+
Keep a checklist sheet per client — Form 16 received, AIS checked, bank interest certificates, capital-gains statement — and the agent reads it live during the call, asking only for what is missing. When a client says they have sent something, it records the promise and date. Your team updates the sheet as documents arrive, and the next campaign skips completed items.
Is July too late to start calling?
+
Often, yes. Employers must issue Form 16 by 15 June, so most practices start then, with a first campaign for documents and a second in early July for stragglers. Starting earlier for business clients spreads the workload further. Bulk campaigns can reach several hundred clients in a day, so the real limit is your team's preparation capacity, not reaching people.
