How to read a payslip in 2026: gross salary, deductions and tax reliefs

A payslip often looks more complicated than it really is. In practice, it shows how your gross salary turns into the net amount that reaches your bank account.

In 2026 the principle remains the same: social insurance, health insurance and tax advance payments are deducted from gross salary. The final amount can then change because of tax reliefs and child tax benefits.

What to check on a payslip

1. Gross salary
   The base amount agreed in your contract or salary statement.

2. Social insurance
   Mandatory employee contribution for pension and sickness insurance.

3. Health insurance
   Calculated as a percentage of gross salary and deducted from net pay.

4. Tax advance
   Calculated after applying taxpayer declaration and tax reliefs.

5. Child tax benefit
   For some employees this can significantly affect the final net salary.

Why net salary changes month to month

Common reasons include bonuses, allowances, unpaid leave, sick leave or a change in the number of children claimed in a given month. The result also depends on whether you signed the taxpayer declaration.

When a salary calculator helps

If you want to quickly verify whether the amount on your payslip makes sense, an online calculator is the fastest option. You can compare different gross salaries, reliefs and family situations in a minute.

Final practical tip

Keep your payslips archived. They are useful for annual tax reconciliation, mortgage applications and resolving payroll discrepancies.
