Personal Tax
Tax bills feel opaque until you compute one yourself. These courses walk through the mechanics with a simplified, illustrative tax system: brackets and allowances, credits, effective and marginal rates, withholding on a payslip. You build each step in a spreadsheet and the checker confirms the result, so the logic of a real return becomes much easier to follow.
The 6 courses cover income tax computation, gross-to-net payslips and year-end refunds, side income and self-employment, property, wealth and inheritance taxes, and a capstone workbook that takes you from source documents to a refund or balance due.
