It is an eternal question and the most common dilemma for young workers entering the job market for the first time: "My friends say they got a salary of X and only talk about the net, but in modern business, the only fair legal norm is – absolute GROSS negotiation."
The Labor Law usually very directly mandates that the salary be defined exclusively in its corresponding GROSS amount on the employment contract itslef. Although you may informally "agree on a net" during a verbal conversation, only the Gross amount is recognized in writing, in court, and by law.
The psychology here is clear: the worker negotiates with the bank for a "fixed 1,000 EUR available every 15th of the month" to cover loan installments and living costs. They aren't concerned with state calculations. However, this path of comfort hides significant legal and economic traps that work extremely and exclusively in favor of the employer!
It would be very unwise to claim tax deductions for children while having a fixed net agreement. Dependents and disability make you eligible for higher "Personal Deductions" which, in a gross arrangement, would drastically cut your taxes and contributions and significantly increase your net payout.
If you agree on a fixed net of 1,500 EUR with a bad employer, they might set a low Gross (corresponding to a 900 EUR net) and "add" the remaining 600 EUR through categories like "Work from home allowance", "Rewards", or "Travel expenses". You end up with 1,500 EUR in your account. The catch? These "add-ons" of 600 EUR are absolutely exempt from state contributions to your Pension and Health insurance. This means when you apply for a bank loan, the system says you have a meager 900 EUR income, and the bank will likely reject you, while your future pension potential is crippled.
Demanding clearly defined gross negotiation shows management that they are dealing with a person highly aware of labor laws and business practices. By negotiating exclusively in Gross, you protect yourself and your future pension. Don't forget to use our Calculator to elegantly convert a proposed gross amount into your expected net figure.
