Questions people ask

  • Do you store what I type?

    Your figures are calculated in your browser. Analytics and the optional feedback form are separate; see the Privacy page. If you choose to save a scenario or download a summary, it is kept only in your own browser storage, and you can clear it at any time. Like most sites, we keep ordinary server logs and use analytics and advertising cookies; the privacy policy explains what they cover.

  • Who builds this, and is it reviewed by a Chartered Accountant?

    HeyArtha is built by Shivam, a CA Intermediate student. He is not a Chartered Accountant, and the tools are not reviewed by one. Each tool states its method and sources on its own pages, and the test records show how it was compared. For a decision that matters, check your own case with a practising professional.

    About HeyArtha
  • How do you check the results?

    Tools are compared with an independent calculation, a second program written separately from the tool, and the differences are listed. Test records are published tool by tool, so some tools are still in preparation. The Test records section above shows which tools have a record, how many cases were compared and how many differences were listed.

    How the working is checked
  • Which tax year and law do the calculators use?

    Each tool page states the tax year or financial rules it uses. Tax calculators implement Tax Year 2026-27 and the Income-tax Act 2025, as amended by Finance Act 2026. Non-tax tools, covering loans, personal money, or investments, use standard financial mathematics rather than statutory tax law. The sources page outlines the legal sections and mathematical baselines behind every tool.

    Statutory sources
  • Is this tax, legal or investment advice?

    No. Everything on HeyArtha is educational information. The calculators show how a figure is worked out under stated rules and assumptions, and the guides explain ideas in plain language. They do not take your whole situation into account. For advice on your own affairs, speak to a qualified professional who can see all your facts.

  • What is the Daily Brief?

    The Daily Brief is an evening summary of finance and tax news, with the source named on each story so you can read the original. It publishes most evenings between 7 and 11 pm IST. Separate pages cover exam updates, traders and tax news, and the brief archive keeps earlier editions.

  • I think a result is wrong. How do I tell you?

    Use the feedback page, and say which tool you used, what you entered and what you expected to see. Tool pages that have a Report a mismatch link lead to the same place. Changes to rules and rates are recorded on the public changelog, so you can see what was changed and when.
