1. PROJECT OVERVIEW
TaxSmooth.ai is a B2C, wizard-driven, cloud-based Indian income tax return (ITR-1 / Sahaj) preparation and filing SaaS platform built for Assessment Year 2025-26.
The platform guides Indian resident individual taxpayers step by step through entering their income details, selecting deductions, computing tax liability under both New and Old Tax Regimes, and generating a legally compliant ITR-1 JSON file conforming to the CBDT's official schema (ITR-1_2025_Main_V1_2.json). The platform also produces a human-readable PDF tax summary and provides step-by-step instructions for manual submission to the IT Department's e-filing portal at eportal.incometax.gov.in.
An embedded AI-powered chatbot (TaxBot) provides real-time guidance on any wizard screen, grounded in the Income Tax Act 1961, CBDT circulars, and ITR-1 instructions through a Retrieval-Augmented Generation (RAG) pipeline. An optional human expert review service allows a support agent to access the user's return data — with the user's explicit in-platform consent — to provide personalised guidance.
The platform is designed for three primary personas: Ramesh, a first-time salaried filer who needs hand-holding through every step; Savitri, a senior pensioner with low tech literacy who benefits from plain language and proactive chatbot guidance; and Priya, an experienced annual filer who wants speed, accuracy, and a side-by-side tax regime comparison with minimal clicks.
