AI in Tax Filing: The Future of Income Tax with Large Language Models

India is gearing up for this big overhaul of its tax framework, Income-tax Rules, 2026 . But something weird is happening online. People are actually using artificial intelligence to file their income tax returns.

It started small just some professionals experimenting. Now it’s exploded across LinkedIn and Reddit. Some folks are calling the AI a virtual chartered accountant. Others? They're absolutely terrified about handing over sensitive financial data to these large language models. The debate is already raging.

One of the biggest stories came from Bengaluru, where an info security specialist named Uddeshya Kumar was involved. He claimed he used Anthropic’s Claude desktop app for almost the entire tax filing process.

Kumar described it as running like having a CA sitting right next to him. Largely seamless, he said.

He managed everything: analyzing his Form 16, cross-checking income against the Annual Information Statement (AIS). Finding discrepancies. Handling that mess when his employer changed mid-year. Sorting out portal issues and those frustrating session timeouts. Then, finally filing it all.

“The whole thing ran like a CA sitting next to me,” Kumar put it.

He felt AI could actually navigate government portals, read the documents, spot errors, and file on your behalf. It sounds futuristic, maybe too much for some people.

He even shared the exact prompt he used to guide Claude through this whole ordeal. It laid out everything: document requirements, verification steps, how to handle pop-ups and login interruptions.

The prompt looked like this:

Role: Expert CA via Chrome MCP
Task: ITR-1 Filing
Parameters: [AY] | [Regime] | [City] | [Employment Type]

Prerequisites included Form 16 for every employer, final settlement slips for job switches, bank details. And things like deciding on the city and whether a secondary address existed. A whole workflow laid out step by step from dashboard to resume filing, making sure you never hit “File Now” until everything was checked. It forced him to confirm Personal Info, GTI, Deductions, Tax Paid, Liability in strict order. Then verification, previewing, checking declarations... Aadhaar OTP e-verify.

But there were the session rules too. You had to navigate only through the UI, no direct URL clicks to avoid logging out automatically. And those annoying dual login popups you clicked ‘Login Here,’ you ignored the logout prompts. Timeout? Just re-login and resume. It was a protocol built around avoiding friction.

Still, the reaction wasn't unanimous. When one LinkedIn user questioned if filing through Claude was actually safe, Kumar defended it strongly.

“Fair question,” he pushed back. “But think about what most people do: they share PANs, Form 16s on WhatsApp with a CA. They upload salary slips to ClearTax or Quicko. They give login access to some portal they’ve never audited.” He paused there. “I did none of that. Claude ran inside my own browser. I was in control the entire time. I reviewed the summary before anything went through.”

He admitted it wasn't fully autonomous either. “This workflow was running with Human In Loop ,” he clarified. But even with that, concerns about privacy and security just kept dominating the conversation. Where does all that personal data actually end up? Could it be used for training models? People argue hard AI should just be a tool, not a replacement for actual professional expertise.

Then there was Akhil Sood, a senior executive at Amazon in Washington, US. For him, the appeal wasn't automation; it was understanding. He used an AI assistant to file his Indian ITR as a non-resident Indian, and he found it surprisingly educational.

Tax filing always felt unnecessarily complicated for him back then. It involved endless searching for CAs, coordinating paperwork, waiting around for replies just trying to grasp the terminology.

What really stuck with Sood was that the AI didn't just spit out answers. It explained why certain fields existed. What information they needed to verify. How different income categories worked. What checks were necessary before you submitted anything.

This reduced his reliance on middlemen. More importantly, it improved his grasp of compliance. He noted the AI could actually flag issues on the tax portal and suggest ways to raise grievances things that usually just stall a filing process.

The timing of all this feels significant. India’s entire tax ecosystem is shifting right now. The Income-tax Rules, 2026 are coming. They aim to simplify things new form numbering, new disclosures, streamlined compliance workflows. This digital experiment? It lands right in the middle of that structural change.
