Data sources

Every rule we use, where it comes from, and when we last checked it.

We never make up exam specs, age limits, tax slabs or formulas. Each value lives in a typed data file with its official source and a "last verified" date. If we could not confirm a value, it is marked Unverified, the tool shows a warning, and no dedicated page is created for it.
