Why do employees with the same gross salary receive different take-home pay?

In many companies, employees often compare their salaries and ask a logical question:
how is it possible that, with the same gross salary, each person receives a different net amount?

At first glance, this may seem like a payroll error. However, in most cases, it is the result of correctly applied taxes.

In this article, we will look at the main factors that affect net salary and explain why the same gross salary does not necessarily result in the same take-home pay.

1. Tax information and applied allowances

This is the main factor that affects net salary.

Key points to consider:

• whether the employee’s tax information is submitted to the specific employer
• what allowances are applied (e.g. dependents, disability, etc.)

If the tax information is not submitted:
👉 the non-taxable minimum is not applied
👉 allowances are not applied
👉 the take-home pay is lower

If the tax information is submitted:
👉 all applicable allowances are applied
👉 the take-home pay is higher

2. Allowances for dependents

Employees who have dependents (for example, children) are entitled to tax allowances.

This means:

• lower personal income tax
• higher take-home pay

👉 Even with the same gross salary, the difference can be significant.

3. Additional tax allowances

Some employees may be entitled to additional allowances, such as:

• disability allowances
• other tax reliefs provided by law

👉 This reduces the overall tax burden and increases net salary.

4. Actual time worked

Even if the same gross salary is specified in the employment contract, the actual amount paid may differ if:

• the employee works part-time
• there has been sick leave or vacation
• the number of hours worked in the month varies

👉 In such cases, the actual gross salary for the specific month differs, which also affects the net salary.

❗ Important to note

Employers do not always have access to all information regarding the tax allowances applicable to an employee, and they are not authorized to modify the employee’s tax information.

👉 Therefore, differences in net salary are usually not an error, but a normal outcome.

📊 Example

In practice, the difference can be significant, as illustrated by the following example:

👉 Difference: 267,75 €

📌 Conclusion

The same gross salary does not necessarily mean the same net salary.

It is affected by:

• employee tax information and applicable allowances
• dependents
• additional tax allowances
• actual time worked

👉 Therefore, payroll calculations are always individual.
