Personal income tax

Income tax applies to taxable income = income − deductions (self, dependents). It is progressive: higher income, higher rate on the upper part.

Let’s explore

🧾
There are deductions (self, dependents) before tax is computed.
📊
Progressive by bracket: only the high part is taxed at a high rate.
🏛️
Paying tax correctly is a civic duty; evasion is illegal.
