COPYFor understanding the mechanics, build a toy payroll calculator — never use it for real payroll: 1. Gross-to-net pay calculation given a fixed set of tax rates you enter yourself — genuinely simple arithmetic once the rates are inputs, not something you look up correctly yourself. 2. Employee records and a PDF pay-stub template — ordinary CRUD plus an existing PDF-generation library. 3. Label the output clearly as a learning project, not a real payroll system. That's a fine, safe way to understand payroll math. Out of scope, permanently: actual tax withholding and filing — correct, current tax rates across every jurisdiction you have employees in is a serious, ongoing compliance surface with real financial and legal consequences — and direct deposit, which requires real banking-network integration, not a database update.
