1. What is URSSAF?
URSSAF — Union de Recouvrement des cotisations de Sécurité Sociale et d'Allocations Familiales — is a French national network of organizations responsible for a public service mission: collecting social contributions that fund the French social protection system.
Concretely, these contributions feed:
- Health insurance (CPAM) and maternity, disability, death insurance
- Basic retirement insurance (CNAV)
- Family allowances (CAF)
- Unemployment insurance (France Travail/UNEDIC) and continuing education
- In-kind and cash benefits of social security
- Funding of the 5th risk (autonomy / dependency)
The URSSAF network is steered by ACOSS (now "Caisse nationale URSSAF"). It includes 22 regional URSSAF in mainland France, plus the CGSS in overseas departments.
2. Who does URSSAF apply to?
URSSAF concerns several audiences with very different regimes:
- Companies and employers: declaration and payment of social contributions on salaries via the DSN (Déclaration Sociale Nominative).
- Standard freelancers: artisans, traders, liberal professions (general regime since the abolition of the RSI in 2018-2020).
- Micro-entrepreneurs: simplified regime with monthly or quarterly turnover declaration on autoentrepreneur.urssaf.fr.
- Artist-authors: regime managed by URSSAF Limousin (artistes-auteurs.urssaf.fr) since 2019, replacing MDA and AGESSA.
- Individual employers: use of CESU URSSAF or Pajemploi for online declaration.
- Employer nonprofits: for employee compensation (DSN or Impact emploi scheme).
- Occasional show employers: via GUSO (Single Window for Occasional Shows).
3. URSSAF contributions in detail
Without going into rate details (which evolve over time and according to your situation, sector and department), URSSAF contributions are split into several major categories:
- Social Security contributions: sickness, maternity, disability, death, basic retirement, AT/MP (work accidents / occupational diseases).
- Family allowances (paid to CAF).
- CSG / CRDS: General Social Contribution and Contribution to the Reimbursement of Social Debt.
- Employment-related contributions: continuing professional training (CFP), mobility levy, FNAL (National Housing Aid Fund), social dialogue contribution, single contribution to training and apprenticeship (CUFPA).
- Unemployment insurance: since 2019, unemployment contributions are collected by URSSAF.
4. How to declare to URSSAF
Companies and employers: the DSN
The Déclaration Sociale Nominative (DSN) is the monthly dematerialized declaration that groups social and tax information about employees. It replaces almost all old declarations.
Standard freelancers
Annual declaration of professional income, with payment of provisional installments calculated on N-2 income, then adjustment after declaration.
Micro-entrepreneurs
Monthly or quarterly declaration of turnover on autoentrepreneur.urssaf.fr. Immediate payment of corresponding contributions.
Individual employers
Use of CESU URSSAF (personal services) or Pajemploi (child care at home, registered childminder).
Artist-authors
Annual artistic income declaration on artistes-auteurs.urssaf.fr.
5. Individual employer & CESU URSSAF
The CESU URSSAF (Chèque Emploi Service Universel) is a simplified scheme for individuals employing someone at their home: cleaning, ironing, gardening, tutoring, support for elderly people, etc.

6. Payment and deadlines
Payment terms vary by status: monthly or quarterly for employers (DSN), monthly or quarterly installments for freelancers, immediate for micro-entrepreneurs, automatic monthly debit for individual employers (CESU URSSAF).
7. Payment difficulties and solutions
URSSAF offers several mechanisms in case of financial difficulty:
- Payment delay: spreading contributions over several months.
- Settlement plan: for older debts.
- Gracious remission of penalties under conditions.
- Emergency aid via the CATS Fund for some self-employed in great difficulty.
8. URSSAF audit: how to prepare
URSSAF has audit power over employers and freelancers. The audit can cover the last 3 years (5 years in case of undeclared work). You are notified by a 15-day prior notice.
Documents to keep
- Payslips and personnel register (employers)
- Employment contracts
- Proof of paid contributions
- Accounting documents
- Conventions and amendments
Generally keep these documents at least 5 years, sometimes 10 years for accounting.
9. Formal notices, constraints and appeals
If you don't pay on time, URSSAF may initiate a recovery procedure: observation letter, formal notice, constraint, seizure.
Your appeal options
- Friendly appeal before the CRA (Commission de Recours Amiable): within 2 months of the decision.
- Contentious appeal before the social pole of the judicial court: within 2 months of the CRA decision.
- URSSAF mediation: national mediator accessible via your personal account.
10. Ten common mistakes to avoid
- Failing to declare on time (even zero turnover for micro-entrepreneurs)
- Under-declaring hours or compensation
- Not updating bank information
- Ignoring URSSAF letters
- Not keeping supporting documents
- Forgetting to declare a change of situation
- Confusing social and tax declarations
- Believing you're exempt because the activity is occasional
- Neglecting appeal deadlines (2 months)
- Giving up on requesting a payment plan out of fear or unfamiliarity
11. Frequently asked questions about URSSAF
Is URSSAF mandatory?
Yes. Anyone or any entity paying compensation or carrying out a professional activity under the general regime must declare and contribute to URSSAF.
What's the difference between URSSAF and Sécurité sociale?
URSSAF collects contributions. Sécurité sociale (CPAM, CNAV, CAF…) pays benefits. URSSAF is the "collection service" of the French social system.
What if I receive a URSSAF formal notice?
Don't ignore it. Verify the situation, dispute if necessary within legal deadlines (2 months), or request a payment plan.
How to contact URSSAF?
Via your personal account on the URSSAF portal corresponding to your status, by phone, or in agency by appointment.
Can I pay URSSAF contributions in installments?
Yes, on a motivated request for "payment delay", generally via your personal account.
Can URSSAF seize my accounts?
Yes, after an unanswered formal notice and constraint procedure. Seizure is the final step. It can be avoided by a payment plan or timely appeal.
