itr-wala — Indian Income Tax Return (ITR) Filing Assistant

A step-by-step skill that prepares an Indian resident individual's ITR for FY 2025-26 (AY 2026-27), from document extraction to deterministic tax computation, form selection and portal walkthrough.

UtilitiesIntermediate★ 871⑂ 126AI score 9/10Last updated: Sep 2, 2026

What it does

  • Reads Form 16, AIS (JSON), TIS, Form 26AS and broker Tax P&L files (Zerodha/Groww/Upstox) into a strict income.json, recording the source of every figure in extraction notes.
  • Delegates all arithmetic to scripts/tax_engine.py (golden tests + property fuzzer): old vs new regime comparison, 234A interest, 234F fee, s.288A/288B rounding. The model is forbidden from doing tax math itself.
  • Cross-checks totals against AIS/26AS with scripts/validate_income.py (errors block computation), runs a deductions interview, selects ITR-1/2/3/4, and produces filing-pack.md with a portal field map and the exact payable/refund figure.
  • Privacy and safety rails: never asks for passwords, OTPs or bank details; blind extraction helpers keep PAN/account identifiers out of context; Pay, Submit and e-Verify are always the user's own actions.

Who it's for

  • Indian resident individuals self-filing salary, interest/dividend, equity or mutual fund capital gains, crypto, or presumptive freelance income.
  • Anyone who wants a clean, reviewable computation pack before handing it to a CA.
  • Out of scope: non-resident/RNOR, F&O or intraday, audit cases, foreign tax credit, indexation-option property sales, any AY other than 2026-27.

Examples

  1. "Help me with my taxes" — sets up a workspace, lists the documents needed, then builds the return from Form 16 + AIS.
  2. "Which regime is better for me?" — runs the engine and shows the verbatim comparison table plus rupee savings and proof warnings.
  3. "Compute capital gains from my Zerodha Tax P&L" — classifies equity vs non-equity and lets the engine apply the aggregate ₹1,25,000 LTCG exemption.
