Gross income (Bruttoeinkommen, salaire brut, retribuzione lorda) is the amount printed on top of your payslip. It is the figure used in negotiations, mortgage affordability tests and most statistical comparisons of pay.
For employees, gross typically includes base salary, bonuses, 13th-month payments, allowances and the monetary value of certain benefits in kind. Stock grants, company cars and meal vouchers often add to taxable gross even if no cash changes hands.
Self-employed and freelancers calculate gross differently — usually revenue minus business expenses. From that gross they then pay both employee and employer shares of social contributions, which is why their effective tax burden is typically higher than for salaried workers on the same headline.
A German engineer with a EUR 75,000 base salary, EUR 6,000 bonus and EUR 250/month meal vouchers has a gross income of EUR 84,000 for tax purposes.
