Gross to Net Salary Differences by Tax Structure
Tax Deductions: Income tax + social contributions + payroll deductions reduce gross salary.
Payroll Charges: Insurance contributions and employment-based deductions affect net salary.
Income-Based Tax: Salary tax is applied in slabs or percentage-based systems depending on income level.
