#income-tax

The tax brain your agent can call. Point Claude, ChatGPT, Cursor, or your own agent at one endpoint and it can look up real GST/VAT, income and company tax rates and run the maths for you. Every answer is source-cited to the national tax authority with a verified-as-of date, so you can see exactly where each number comes from. Free, public, no login, no API key, and nothing is stored. Where coverage is only partial, it says so plainly instead of guessing.
