Why we built these
Every one of these questions reaches us on WhatsApp several times a week — what is my GST on this invoice, how much HRA is actually exempt, how much TDS do I hold back from a contractor. They are quick to answer and there is no reason to make anyone wait for a reply.
So they are here, free, with no sign-up. The tax figures are the rates in force for FY 2026-27 (AY 2027-28) and we update them when the Budget changes them. Where a calculator cannot know something about your case, it says so instead of guessing.
A number is not a filing
This tool gives you the figure. Getting the filing right — the correct form, the documents, the deadline, the department — is the part that costs people money when it goes wrong. Send us your case and we will tell you what actually applies to you.
