3.3 Urssaf / Social Charges Patterns
| Pattern | Treatment | Notes |
|---|---|---|
| URSSAF PRÉLÈVEMENT / URSSAF AUTO ENTREPRENEUR | Social contributions (not IR) | Urssaf collects social charges on gross turnover; not an expense deduction for micro-entrepreneurs |
| CIPAV COTISATIONS | Social contributions | Mandatory pension for professions libérales (not regulated) |
| CARPIMKO / CARMF / CARCDSF | Social contributions | Mandatory pension for specific professions |
| PRÉLÈVEMENT À LA SOURCE / PAS | Income tax prepayment | Monthly/quarterly IR withholding -- credit against annual IR |
Input line (BNP Paribas statement):
15/03/2025 | VIR SEPA ABC CONSULTING SARL | +3,500.00 | Solde 12,840.50
Reasoning: Client wire transfer EUR 3,500 for consulting services. Taxpayer is a micro-entrepreneur under BNC (profession libérale). Abattement = 34%. Net taxable income = EUR 3,500 x (1 - 34%) = EUR 2,310. This EUR 2,310 is added to total taxable income for the year. Urssaf social charges are computed separately on the gross EUR 3,500 (approximately 22% = EUR 770), not on the post-abattement amount.
Classification: Recettes brutes EUR 3,500. Taxable income contribution EUR 2,310 (after 34% abattement).
Input line (Société Générale statement):
22/05/2025 | STRIPE PAYMENTS EUROPE | +4,650.00 | Solde 8,220.00
Reasoning: Stripe France settlement. Net of Stripe fees. Check Stripe dashboard: if Stripe collected EUR 4,800 from clients and deducted EUR 150 fees, gross turnover = EUR 4,800. For micro-entrepreneur, Urssaf and IR are based on the gross EUR 4,800. Stripe fee EUR 150 is irrelevant for micro (abattement covers all expenses). For régime réel, the Stripe fee EUR 150 is a deductible expense.
Classification (micro): Recettes brutes EUR 4,800. Abattement 34%/50% as applicable. Stripe fee not separately deductible.
Input line (Crédit Mutuel statement):
01/04/2025 | PRÉLÈVEMENT VIREMENT LOYER BUREAU SARL IMMOPRO | -1,200.00 | Solde 5,640.00
Reasoning: Monthly office rent EUR 1,200. For régime réel BNC filers, rent for a dedicated professional premises is fully deductible as "loyers et charges locatives." For micro-entrepreneurs, this expense is NOT deductible separately -- covered by the abattement.
Classification (réel): Loyers EUR 1,200 fully deductible. (Micro: no separate deduction.)
Input line (LCL statement):
15/06/2025 | PRÉLÈVEMENT URSSAF AUTO ENT | -528.00 | Solde 4,210.00
Reasoning: Urssaf social contribution EUR 528 for micro-entrepreneur. This is a social charge payment based on gross turnover (~22% rate). For income tax purposes (IR), Urssaf contributions are NOT deductible from BNC/BIC income for micro-entrepreneurs. They reduce take-home pay but do not reduce the taxable income figure for IR.
Classification: EXCLUDE from income tax computation. Record for Urssaf reconciliation only.
Input line (Caisse d'Épargne statement):
28/02/2025 | VIREMENT SALAIRE SOCIÉTÉ XYZ | +2,800.00 | Solde 6,150.00
Reasoning: Monthly salary from an employer. This is traitements et salaires (employment income) -- a separate income category from BNC/BIC professional income. Declared on Déclaration 2042 separately. A standard 10% abattement for professional expenses applies to salary income (capped at EUR 14,171 or minimum EUR 504).
Classification: Salaires bruts EUR 2,800. NOT professional income. Declare on 2042 box 1AJ/1BJ.
Input line (BNP Paribas statement):
27/01/2025 | PRÉLÈVEMENT FISCAL DGFIP PAS | -420.00 | Solde 7,890.00
Reasoning: Monthly "prélèvement à la source" (PAS) -- the monthly income tax prepayment deducted by the DGFiP from the bank account of self-employed persons. Based on the prior year's income declaration. It is NOT an expense. It is a prepayment of income tax credited against the annual IR bill.
Classification: EXCLUDE from income/expenses. Record: PAS paid EUR 420/month = EUR 5,040/year (credit against annual IR).

Legislation
CGI Art. 50-0 (BIC); CGI Art. 102 ter (BNC)CGI Art. 50-0; CGI Art. 102 ter
Taxable income formula
Taxable income = Gross receipts x (1 - abattement %).CGI Art. 50-0; CGI Art. 102 ter
Micro regime characteristics
No actual expense deduction; minimum abattement EUR 305 (even if receipts are lower); Urssaf computed on GROSS receipts (not post-abattement); Income tax computed on POST-abattement income via standard IR brackets.CGI Art. 50-0; CGI Art. 102 ter
Applicability and rules
For professions libérales above EUR 77,700 or who opt out of micro: Declare actual receipts and actual expenses on Form 2035. Deductible expenses: rent, telecommunications (business %), travel, professional insurance, accounting fees, equipment depreciation, software. NOT deductible: personal expenses, income tax itself. Partial deductibility of social charges: Madelin health/provident contributions ARE deductible from BNC income.
Tax computation flow
Gross professional receipts (chiffre d'affaires) x (1 - abattement %) for micro, OR - Actual expenses (régime réel) = Net professional income (BNC or BIC) + Other income (salaires, pensions, revenus fonciers) = Revenu brut global - Charges déductibles (alimony, certain pension contributions) = Revenu net global Divide by number of parts (quotient familial) Apply progressive rate table x Number of parts = IR tentative Cap benefit of quotient familial (plafonnement) + CEHR if applicable - Crédits et réductions d'impôt = IR net
PAS rules
Since 2019, French taxpayers pay income tax monthly via PAS (automatic bank debit). For self-employed: Rate based on prior year income (taux personnalisé) or neutral rate for first year; Monthly debit from bank account; At annual declaration time, actual tax is computed; if PAS exceeded, refund issued. PAS payments are NOT expenses -- they are advance payments of the annual IR.
CFE treatment
Local business property tax. Mandatory for all self-employed including micro-entrepreneurs. Deductible expense for régime réel filers. NOT deductible for micro-entrepreneurs.

Optimisation guidance
Micro is simpler but not always optimal. Réel is better when actual expenses exceed the abattement percentage. For BNC professions libérales: if actual costs > 34% of receipts, réel simplifié yields lower tax. For BIC services: if costs > 50% of receipts, réel is better. Flag for reviewer to compute both and advise.
Quotient familial cap
The number of fiscal parts significantly impacts tax. Changes to family situation (marriage, children, divorce) must be declared. The benefit of each additional 0.5 part is capped at EUR 1,751 reduction in tax per half-part (2025 figure). Flag for reviewer to confirm family situation and number of parts.
Tax credits list
Several credits reduce IR directly: Crédit d'impôt garde d'enfants (children under 6): 50% of costs, max EUR 3,500 per child; Crédit d'impôt emploi à domicile (home help): 50% of wages paid, max EUR 12,000; Crédit d'impôt formation du dirigeant: EUR 40/hour of training. Flag for reviewer to identify applicable credits.
Madelin deductions
Contributions to Madelin-qualified health, disability, provident, and pension insurance contracts are fully deductible from BNC income (for régime réel filers). Not available to micro-entrepreneurs.
Home office deduction
For régime réel BNC filers working from home: proportionate rent, electricity, internet, and heating may be deducted based on floor area ratio of the office to total home area. Must be documented and consistent.
