Why compare two salaries?
Comparing salaries helps you evaluate job offers, understand the real impact of a raise, or see how a career change affects your take-home pay. Due to progressive taxation, a 10% raise may only result in a 7-8% increase in net pay.
Does the comparison account for family situation?
Yes, both salaries use the same family status and number of children. The quotient familial reduces income tax, so a married person with children will see a bigger take-home difference between the two salaries.
What costs are included in the comparison?
The comparison includes all employee social contributions (CSG, CRDS, retirement, complementary pension) and income tax with the quotient familial. It shows gross salary, social contributions, net before tax, income tax, and take-home pay.

How to compare salaries across French regions and sectors
How does this work in France?
Salary Comparison in France follows specific French rules set by the DGFiP and Code Général des Impôts. The system is designed to balance social protection with economic activity. Understanding the rules helps you plan your finances and avoid surprises at tax time.
What are the key rates and thresholds?
French rates and thresholds are updated annually in the Loi de Finances. Income tax brackets, social charge rates, and benefit thresholds all change each January. Always check the latest figures on impots.gouv.fr or service-public.fr. Using outdated rates can lead to incorrect calculations and unexpected tax bills.
How does this affect your annual tax return?
All income and deductions must be reported on your déclaration de revenus annuelle, filed online at impots.gouv.fr by mid-May. The tax office cross-references your declaration with employer data (DSN), bank reports, and other sources. Errors can trigger a contrôle fiscal (tax audit) with penalties of 10-40% of undeclared amounts.
What records should you keep?
French law requires keeping all financial records for at least 6 years for tax purposes and 10 years for commercial documents. This includes invoices, receipts, bank statements, contracts, and payslips. Digital copies are accepted if they are legible and stored securely. The fisc can audit any period within these timeframes.
Where can you get help?
For tax questions, contact your SIP (Service des Impôts des Particuliers) or SIE (Service des Impôts des Entreprises). The service-public.fr website has detailed guides. For complex situations, hire an expert-comptable (chartered accountant) — fees range from €500 to €3,000/year. Trade unions (syndicats) and the CAF also provide free advice on social benefits.
What penalties apply for errors?
Late filing: 10% surcharge plus 0.2% per month of interest. Deliberate understatement: 40% penalty. Fraud: 80% penalty plus potential criminal prosecution. If you discover an error, file a déclaration rectificative as soon as possible — voluntary correction reduces penalties. The fisc appreciates good faith and transparent communication.
