AI Prompts That Work in a CA Practice (With Copy-Paste Examples)
- The right AI prompt includes your actual numbers, the specific section of law, and asks for a numbered action list—vague prompts give vague answers.
- AI is a fast first-draft tool; your CA reviews the output before anything goes to the portal or to a client.
- Copy-paste prompts for salary tax planning, GST reconciliation, TDS defaults, and notice replies are ready to use right now.
AI tools like ChatGPT and Gemini can cut hours of routine CA work—but only if you write the prompt correctly. A prompt like "help me with income tax" wastes your time. A prompt that names the section, plugs in real rupee figures, and specifies the output format gets you a usable draft in under two minutes. Below are tested, copy-paste prompts organised by task, plus the common mistakes that make AI output dangerously wrong.
Why Most AI Prompts for CA Work Fail
The problem is not the AI—it is the prompt. Generic prompts produce generic answers. A tax notice reply drafted without the actual notice language, the assessment year, and the specific section cited is useless. Before you use any prompt below, fill in every bracketed field with your real data. That one habit separates useful AI output from hallucinated nonsense.
Salary Tax Planning Prompt (With Live Arithmetic)
Use this prompt for any salaried client or for yourself before the financial year ends:
Prompt to copy:
"I am a salaried employee in India for FY 2026-27. My gross salary is ₹12,00,000. My employer contributes ₹86,400 to EPF. I have declared HRA of ₹1,20,000 (rent paid ₹1,44,000, city: non-metro). I want to compare my tax under the old regime (with deductions) versus the new regime (Section 115BAC). Include standard deduction, Section 80C investment of ₹1,50,000, Section 80D premium of ₹25,000, and the HRA exemption calculation. Show tax slabs used, final tax payable, and which regime saves more money. Use FY 2026-27 rates."
What the AI should produce—and how to verify it:
On a ₹12,00,000 gross salary, the arithmetic works like this under the old regime:
- Gross salary: ₹12,00,000
- Less standard deduction: ₹75,000
- Less HRA exemption (least of: actual HRA received ₹1,20,000 / rent paid minus 10% of salary ₹24,000 / 40% of basic for non-metro—assume HRA exemption works out to ₹24,000 in this case): ₹24,000
- Less Section 80C: ₹1,50,000
- Less Section 80D: ₹25,000
- Taxable income: ₹9,26,000
- Tax at old slab rates (up to ₹2.5L nil, ₹2.5L–₹5L at 5%, ₹5L–₹10L at 20%): ₹12,500 + ₹85,200 = ₹97,700 plus cess at 4% = ₹1,01,608
Under the new regime (FY 2026-27 slabs—up to ₹4L nil, ₹4L–₹8L at 5%, ₹8L–₹12L at 10%, with rebate under Section 87A making income up to ₹12L tax-free for residents):
- Gross salary less standard deduction ₹75,000 = taxable income ₹11,25,000
- Tax before rebate: ₹0 + ₹20,000 + ₹32,500 = ₹52,500 plus cess = ₹54,600
- Note: The ₹12L rebate limit under Section 87A applies to income up to ₹12,00,000; at ₹11,25,000 taxable, the full rebate wipes out tax = ₹0 payable
The AI should flag this clearly. If it does not mention the Section 87A rebate under the new regime, the output is incomplete—correct it before sharing with anyone.

Prompts for Responding to Income Tax Notices
When you receive a notice, paste the exact notice language into the AI with this wrapper:
"Below is an income tax notice I received. Identify: (1) the section under which it is issued, (2) what the department is asking for, (3) the response deadline, (4) a list of documents I should gather, and (5) a draft reply in formal English suitable for submission on the e-filing portal. Notice text: [paste full notice here]."
For a faster starting point, run your notice through KyaTax's Notice Decoder first—it identifies the notice type and the required response before you even open an AI tool.
Making AI Output Safer to Use
AI does not access the live Income Tax portal, GST portal, or MCA. It works from training data with a knowledge cutoff. Always do three things after getting AI output:
- Check the section number. Ask the AI: "Cite the exact sub-section. Are you certain this has not been amended?" If it hedges, verify on incometaxindia.gov.in yourself.
- Verify due dates. CBDT and GSTN routinely extend deadlines. The AI will not know about an extension announced last week.
- Run the arithmetic independently. Copy the numbers into a spreadsheet. AI can make arithmetic errors especially with surcharge and marginal relief calculations.
Common Mistakes When Using AI Prompts for CA Work
These are the errors that lead to wrong filings, rejected notices, or missed deductions:
- Mistake 1 — Omitting the assessment year. Tax rules change every budget. A prompt that says "under Indian income tax" without specifying FY 2026-27 may pull rules from two years ago. Always name the financial year.
- Mistake 2 — Trusting invented section numbers. AI sometimes cites a plausible-sounding section that does not exist or quotes the wrong sub-section. If you cannot find the section on the bare act, the AI hallucinated it. Never submit a notice reply citing a section you have not verified.
- Mistake 3 — Using AI for Part B of Form 16 verification without cross-checking Form 26AS. AI cannot pull live TDS data. It can only work with what you paste in. Always reconcile AI-drafted figures against your actual Form 26AS and AIS.
- Mistake 4 — Skipping the "old vs new regime" comparison for every client. The new regime default and the revised Section 87A rebate mean many salaried taxpayers pay zero tax under the new regime but more under the old—yet people still default to the old regime out of habit. A one-minute AI prompt comparison prevents this every time.
- Mistake 5 — Pasting client PAN, Aadhaar, or bank details into a public AI tool. Use only aggregate numbers and anonymised descriptions. Replace PAN with "XXXXX1234X" and remove all personal identifiers before submitting any prompt to a cloud-based AI.
Building a Prompt Template File for Your Practice
Save your best prompts as a simple text file or Notion page. Structure each entry with: task name, the prompt template with [bracketed placeholders], and a checklist of what to verify before using the output. Update the file after each Budget—rates, rebate limits, and form numbers change annually. A 20-prompt template file built once saves hours every filing season.

Open Notice Decoder →Frequently asked questions
Are AI prompts for CA work legally reliable for filing returns?
No AI output should go directly onto the portal. AI drafts are a starting point. Your CA (or you, if self-filing) must verify section numbers, rates, and due dates against official sources before submission. AI is a research and drafting assistant, not a filing tool.
Which AI tool works best for Indian tax prompts?
ChatGPT (GPT-4 and above) and Google Gemini both handle Indian tax questions well when given specific, detailed prompts. Neither has real-time access to the income tax portal, so always verify time-sensitive information like due dates and challan numbers independently.
Can I use AI to reply to a GST scrutiny notice?
Yes, AI can draft a structured reply if you paste in the exact notice text, your turnover figures, and the documents you hold. The draft must be reviewed by a GST practitioner before submission. Factual errors in a notice reply can worsen your case.
How do I stop AI from giving wrong section numbers in tax prompts?
Add this line to every tax prompt: "If you are not certain of the exact section number or sub-section, say so explicitly rather than guessing." Then independently verify every cited section on incometaxindia.gov.in or the bare GST Act before using the output.
General information for FY 2026-27, not professional advice for your specific case. Rules change — verify against the latest notification or ask a KyaTax expert.
