About these guides
Each guide explains one local rule that shapes the numbers in our calculators — how it works, who it affects, and what to watch for — and links to the calculator that applies it. The guides are written in plain English and checked against the official sources listed at the end of each one. They explain rules; they do not tell you what to do with your money.
