itr-wala - Deterministic Indian ITR Filing

Prepares an Indian resident individual's ITR for FY 2025-26 (or advance-tax plan for FY 2026-27) with every rupee computed by a tested Python engine, leaving pay/submit/e-verify to you.

What it does

  • Reads Form 16, AIS/TIS, Form 26AS and broker P&L files (Zerodha/Groww/Upstox) and transcribes them verbatim into a strict work/income.json.
  • Delegates 100% of tax, interest and fee arithmetic to scripts/tax_engine.py - the model is forbidden from doing math, even sanity checks.
  • Gates computation behind scripts/validate_income.py (must exit 0), cross-checking your totals against AIS/26AS.
  • Produces an old-vs-new regime comparison, a deduction interview (80C/80D/87A/111A/112A), form selection (ITR-1/2/3/4) and a filing-pack.md with a portal field map.
  • Privacy-first: never asks for passwords, OTPs or bank details; encourages redaction of PAN/Aadhaar and uses blind extraction for structured documents.

Who it's for

  • Resident individual taxpayers in India with salary, interest, dividends, equity/MF capital gains, crypto or presumptive freelance income.
  • Anyone who wants an auditable, reproducible computation before handing a pack to a CA.
  • Filers who need quarterly advance-tax instalment planning.

Examples

  1. "Help me file my ITR for FY 2025-26" → workspace created → drop Form 16 + AIS → validate → regime table → filing pack → guided portal walkthrough (you click Pay/Submit/e-Verify).
  2. "How much advance tax do I owe this quarter?" → FY 2026-27 advance-tax workspace with as-of date, expected income and TDS.
  3. "Compute capital gains from my Zerodha tax P&L" → equity vs non-equity classification, with the aggregate ₹1,25,000 LTCG exemption applied by the engine.

Out of scope by design: non-residents/RNOR, F&O or intraday, audit cases, foreign tax credit, ITR-U/revised returns - it tells you and recommends a CA.

Install the skill I found on AI Skill Mart.
Copy the skills/itr-wala folder from the GitHub repo karanb192/itr-wala into my ~/.claude/skills/itr-wala/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/karanb192/itr-wala.git && mkdir -p ~/.claude/skills && cp -r itr-wala/skills/itr-wala ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and confirm Python 3 is available: python3 --version.
  2. Clone the repository: git clone https://github.com/karanb192/itr-wala.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill in: cp -r itr-wala/skills/itr-wala ~/.claude/skills/
  5. Self-test the engine and expect OK: python3 ~/.claude/skills/itr-wala/scripts/test_tax_engine.py
  6. Restart Claude Code and ask something like "help me file my ITR for FY 2025-26".
  7. Put your tax documents in the docs/ folder the skill creates, redacting PAN/Aadhaar where possible - the skill never needs them to compute.
