17# France Tax Optimization -- Self-Employed Skill v1.0
18 
19---
20 
21## Section 1 -- Quick Reference
22 
23| Field | Value |
24|---|---|
25| Country | France (République française) |
26| Key optimization legislation | Code Général des Impôts (CGI) -- Art. 39 (charges déductibles), Art. 44 sexies (ZFU/JEI), Art. 83 (frais professionnels salariés), Art. 154 bis (Madelin), Art. 156 (charges du revenu global), Art. 163 quatervicies (PER), Art. 199 sexdecies (emploi à domicile), Art. 200 (dons), Art. 200-0 A (plafonnement des niches fiscales) |
27| Tax authority attitude to planning | The Direction Générale des Finances Publiques (DGFiP) accepts legitimate optimization. France has a general anti-abuse provision (Art. L64 du Livre des Procédures Fiscales -- abus de droit) and a mini-abuse provision (Art. L64 A LPF) for arrangements with a "principally fiscal" motivation. The Comité de l'abus de droit fiscal advises on borderline cases. |
28| Currency | EUR |
29| Tax year | Calendar year (1 Jan -- 31 Dec) |
30| Filing deadline | Typically May-June of the following year (varies by département and filing method) |
31 
32### Income Tax Rates 2026 (Barème progressif)
33 
34| Tranche | Taxable income per part (EUR) | Rate |
35|---|---|---|
36| 1 | 0 -- 11,497 | 0% |
37| 2 | 11,498 -- 29,315 | 11% |
38| 3 | 29,316 -- 83,823 | 30% |
39| 4 | 83,824 -- 180,294 | 41% |
40| 5 | 180,295+ | 45% |
41 
42Income is divided by the number of parts (quotient familial): 1 per adult, 0.5 per dependent child (1 for the 3rd child onwards). This mechanism itself is a powerful income-splitting tool.
43 
44---
45 
46## Section 2 -- Income Splitting & Structuring
47 
48### Micro-Entreprise vs Régime Réel
49 
50| Factor | Micro-Entreprise (micro-BIC / micro-BNC) | Régime Réel |
51|---|---|---|
52| Turnover ceiling (2026) | EUR 77,700 (services/BNC) / EUR 188,700 (goods/BIC) | No limit |
53| Taxation method | Flat abatement: 34% (BNC) or 50% (BIC services) or 71% (BIC goods) | Actual expenses deducted |
54| When to choose réel | When actual deductible expenses exceed the flat abatement | Always compare before choosing |
55| Social contributions | Based on turnover (micro) vs net profit (réel) | Réel may be lower if expenses are high |
56 
57**Legislation:** CGI Art. 50-0 (micro-BIC), Art. 102 ter (micro-BNC)
58 
59### Quotient Familial (Family Splitting)
60 
61| Parts | Family situation |
62|---|---|
63| 1 | Single, no children |
64| 2 | Married/PACS, no children |
65| 2.5 | Married/PACS, 1 child |
66| 3 | Married/PACS, 2 children |
67| 4 | Married/PACS, 3 children (1 full part from 3rd child) |
68 
69**Strategy:** The quotient familial significantly reduces the marginal rate. A married couple with 3 children earning EUR 120,000 pays substantially less than a single person with the same income. However, the benefit per half-part is capped at EUR 1,759 (2026).
70 
71**Legislation:** CGI Art. 193-197
72 
73### EURL/SARL vs Entreprise Individuelle
74 
75| Factor | Entreprise Individuelle | EURL/SARL (IS option) |
76|---|---|---|
77| Top marginal rate | 45% + social charges (~45%) | IS: 15% (up to EUR 42,500) / 25% above |
78| When to consider | For simplicity and lower income | When profits exceed ~EUR 60,000 and can be retained |
79| Rémunération du gérant | N/A | Salary deductible from company profit, taxed as income for gérant |
80 
81---
82 
83## Section 3 -- Deductions Most People Miss
84 
85| Deduction | Legislation | Notes |
86|---|---|---|
87| Cotisations sociales (self-employed SSC) | CGI Art. 154 bis | CSG déductible (6.8% of total 9.2% CSG) is deductible from taxable income. CRDS (0.5%) is not deductible. |
88| CSG déductible | CGI Art. 154 quinquies | 6.8% of 9.2% total CSG on earned income. Often missed -- automatically deductible but verify it is correctly reported. |
89| Frais de véhicule (barème kilométrique) | CGI Art. 83-3° | Use the official barème kilométrique for business travel. For a 6 CV car doing 15,000 km/year: ~EUR 5,500 deduction. Includes fuel, insurance, depreciation, maintenance. |
90| Home office (local professionnel) | CGI Art. 39, Art. 93 | Proportion of rent, utilities, insurance for dedicated professional space. Calculate by floor area ratio. |
91| Formation professionnelle | CGI Art. 39, Art. 93 | Training, certifications, conferences related to current activity. Fully deductible. Crédit d'impôt formation (up to EUR 878 for 2026 for dirigeants of TPE). |
92| Cotisations professionnelles | CGI Art. 93 | Ordres professionnels, syndicats, associations professionnelles. |
93| Frais de repas (solo meals) | CGI Art. 93; BOI-BNC-BASE-40-60-60 | Meals taken alone during work: difference between actual cost and the forfait repas pris au domicile (EUR 5.35 in 2025). Max deductible: ~EUR 14.65/meal (EUR 20.00 ceiling - EUR 5.35). |
94| Intérêts d'emprunt | CGI Art. 39-1-1° | Interest on loans taken for professional purposes is deductible. |
95| Assurances professionnelles | CGI Art. 39, Art. 93 | RC Pro, prévoyance complémentaire Madelin (within limits), multirisque professionnelle. |
96| Dons aux œuvres | CGI Art. 200 | 66% tax reduction on donations to eligible charities (up to 20% of taxable income). 75% for "Coluche" organizations (meals for the needy), capped at EUR 1,000. |
97 
98---
99 
100## Section 4 -- Capital Allowances Optimization
101 
102**Legislation:** CGI Art. 39 (amortissements), Art. 39 A (dégressif)
103 
104### Amortissement Linéaire (Straight-Line) vs Dégressif (Declining Balance)
105 
106| Method | When to use | Coefficient (for assets with useful life ≥ 3 years) |
107|---|---|---|
108| Linéaire | Default method, equal annual deductions | N/A |
109| Dégressif | Accelerated deductions in early years. Available for industrial equipment, certain IT assets. | 3-4 yrs: ×1.25; 5-6 yrs: ×1.75; 7+ yrs: ×2.25 |
110 
111### Timing of Purchases
112 
113Under both methods, depreciation starts from the date the asset is put into service. For dégressif, depreciation starts from the first day of the month of acquisition (pro-rata to 1/12ths). Purchase in January rather than December to maximize the first-year deduction under dégressif.
114 
115### Low-Value Assets
116 
117Assets under EUR 500 HT can be immediately expensed without depreciation (tolérance administrative). Above EUR 500 HT, depreciation is required.
118 
119### Suramortissement (Super-Depreciation)
120 
121Certain categories of investment benefit from additional depreciation (40% extra over the useful life): industrial robotics, digital transformation equipment, energy transition assets. Check annually for eligible categories.
122 
123**Legislation:** CGI Art. 39 decies and following
124 
125---
126 
127## Section 5 -- Loss Utilization
128 
129**Legislation:** CGI Art. 156 I, Art. 156 I bis
130 
131| Relief | Detail | Limit |
132|---|---|---|
133| Déficit BIC/BNC against global income | Professional losses (BIC/BNC professionnel) can offset other income (salaries, pensions, rental) in the same year | Unlimited for professional deficits |
134| Carry-forward | Unused deficit is carried forward for 6 years against profits of the same category | 6-year limit |
135| Non-professional losses (BIC/BNC non-professionnel) | Cannot offset other categories -- only offset against future profits from the same non-professional activity | 6-year carry-forward, same category only |
136| Déficit foncier (rental losses) | Rental losses from deductible expenses (not interest) offset global income up to EUR 10,700/year | EUR 10,700/year against global income; excess carries forward 6 years for foncier, 10 years for interest |
137 
138### Strategy
139 
140If starting a business with heavy initial costs, structure as a profession libérale or commercial activity (BIC/BNC professionnel) so that first-year losses can be offset against any other income (salary, pension). This is unavailable for non-professional activities.
141 
142---
143 
144## Section 6 -- Timing Strategies
145 
146| Strategy | Detail |
147|---|---|
148| Defer revenue | Under micro-BNC/BIC, revenue is recognized when received (encaissements). Delay invoicing to January. Under régime réel BNC (déclaration contrôlée), the same cash-basis principle applies. |
149| Accelerate expenses | Prepay deductible expenses (insurance, subscriptions, training) before 31 December. Under BNC déclaration contrôlée, expenses are deductible when paid. |
150| PER contribution timing | Maximize PER contributions before 31 December. Contributions are deductible from the current year's income. Unused deduction capacity can now be carried forward for 5 years (previously 3), with spouse pooling. |
151| Quotient familial optimization | Declare PACS or marry before 31 December to benefit from joint taxation for the entire year. |
152| Versement libératoire timing | Under micro, the versement libératoire (flat tax on turnover) is monthly or quarterly. Manage cash flow around payment dates. |
153| Income smoothing (système du quotient) | For exceptional income (Art. 163-0 A CGI), apply the quotient system: add 1/4 of exceptional income to normal income, calculate marginal tax, multiply by 4. Reduces effective rate on lumpy income. |
154 
155---
156 
157## Section 7 -- VAT Optimization (TVA)
158 
159**Legislation:** CGI Art. 293 B (franchise en base), Art. 302 septies A (régime simplifié)
160 
161| Strategy | Detail |
162|---|---|
163| Franchise en base de TVA | Below EUR 36,800 (services) or EUR 91,900 (goods): no TVA charged. No input TVA recovery. Competitive advantage for B2C. |
164| Opt for TVA | If significant input TVA (investment phase), opt to charge TVA to recover inputs. Lock-in: 2 calendar years. |
165| Régime simplifié | Annual TVA return with 2 quarterly acomptes. Available if turnover < EUR 840,000 (goods) / EUR 254,000 (services). |
166| TVA sur les débits vs encaissements | For service providers: TVA on encaissements (payment received) defers TVA liability vs. débits (invoice date). |
167| Autoliquidation (reverse charge) | For intra-EU B2B services: no French TVA charged. Report via DES/DEB. |
168 
169---
170 
171## Section 8 -- Social Security Optimization
172 
173**Legislation:** Code de la Sécurité Sociale; Loi de financement de la Sécurité sociale 2026
174 
175### Cotisations Sociales Structure (Travailleurs Non-Salariés / TNS)
176 
177| Contribution | Rate (approximate) | Base |
178|---|---|---|
179| Assurance maladie-maternité | 0-6.5% (progressive) | Net profit |
180| Allocations familiales | 0-3.1% (progressive) | Net profit |
181| Retraite de base (CNAV) | 17.75% up to PASS; 0.6% above | Net profit |
182| Retraite complémentaire (RCI) | 7-8% up to 4× PASS | Net profit |
183| Invalidité-décès | 1.3% | Net profit |
184| CSG/CRDS | 9.7% | Revenue + cotisations |
185| CFP (formation) | 0.25% of PASS | Flat contribution |
186| **Total effective rate** | **~40-45%** of net profit | |
187 
188### Optimization Strategies
189 
190| Strategy | Detail |
191|---|---|
192| ACRE (first year) | 50% reduction in social contributions for the first year of business creation. Automatic for micro-entrepreneurs since 2020. |
193| Micro vs réel social base | Under micro, social contributions are calculated on turnover (after flat abatement). Under réel, on net profit. Compare both. |
194| Cotisation minimale | Below a minimum profit level, minimum contributions apply. In a loss year, you still pay minimum health/retirement contributions. |
195| Conjoint collaborateur | A spouse working in the business without salary can be registered as conjoint collaborateur for social coverage at reduced cost. |
196| PER contributions as social deduction | PER Madelin/154 bis contributions reduce the social contribution base for TNS if deducted from BIC/BNC profit. |

200## Section 9 -- Investment & Retirement
201 
202### Plan d'Épargne Retraite (PER) -- CGI Art. 163 quatervicies / Art. 154 bis
203 
204| Feature | Detail |
205|---|---|
206| PER individuel (salarié/particulier) | Deductible contributions up to 10% of net taxable income, max EUR 38,448 (2026) or EUR 4,806 minimum |
207| PER Madelin / TNS (Art. 154 bis) | Additional deduction: 15% of profit between 1× and 8× PASS. Total TNS envelope up to ~EUR 88,911 (2026). |
208| Combined TNS deduction | Up to EUR 88,911/year for a high-earning TNS. At TMI 45%, this yields ~EUR 40,000 in tax savings. |
209| Carry-forward of unused allowance | Now 5 years (extended from 3 years by Loi de Finances 2026). Spouse pooling maintained. |
210| Exit taxation | Capital: IR + social charges (18.6% in 2026). Annuity: IR + social charges. |
211| Age limit (from 2026) | Contributions after age 70 are no longer deductible for PER (not applicable to old PERP/Madelin). |
212| Non-deduction option | At TMI 0% or 11%, opt for non-deduction: no tax benefit at entry, but tax-free capital at exit. |
213 
214**Strategy:** For TNS at TMI 41% or 45%, maximize PER contributions. At EUR 88,911 with TMI 45%, the annual tax saving is EUR 40,010. For lower TMI (11%), consider the non-deduction option.
215 
216### Assurance-Vie
217 
218| Feature | Detail |
219|---|---|
220| Tax treatment after 8 years | EUR 4,600 (single) / EUR 9,200 (couple) annual tax-free withdrawal on gains. Above: 7.5% + social charges (if older contracts). |
221| No deduction at entry | Not deductible from income tax. But tax-efficient for long-term savings and estate planning. |
222| Succession | Up to EUR 152,500 per beneficiary tax-free if funded before age 70. |
223 
224### Réductions d'Impôt (Tax Credits/Reductions)
225 
226| Reduction | Rate | Cap | Legislation |
227|---|---|---|---|
228| Emploi à domicile | 50% | EUR 12,000/year (+EUR 1,500/dependent, max EUR 15,000) | CGI Art. 199 sexdecies |
229| Dons aux œuvres | 66% (general) / 75% (Coluche) | 20% of taxable income / EUR 1,000 | CGI Art. 200 |
230| IR-PME (Madelin investment) | 18-25% | EUR 50,000 (single) / EUR 100,000 (couple) | CGI Art. 199 terdecies-0 A |
231| Crédit d'impôt formation dirigeant | ~EUR 878 (2026) for TPE | Forfait annuel | CGI Art. 244 quater M |
232| Plafonnement global des niches | EUR 10,000/year | All reductions combined | CGI Art. 200-0 A |
233 
234---
235 
236## Section 10 -- Red Lines
237 
238| Risk | Detail |
239|---|---|
240| Abus de droit (Art. L64 LPF) | Arrangements that are fictitious or have a tax purpose as their sole motivation can be recharacterized by the DGFiP. Penalty: 80% surcharge. |
241| Mini abus de droit (Art. L64 A LPF) | Arrangements with a "principally fiscal" (not solely) motivation can also be challenged. Lower threshold than L64. Penalty: 40% surcharge. |
242| Plafonnement des niches fiscales | Total tax reductions/credits capped at EUR 10,000/year (EUR 18,000 for overseas/Sofica). Exceeding the cap: lost forever. |
243| Non-professional activities | Losses from non-professional BIC/BNC cannot offset other income. If activity is non-professional, loss utilization is severely limited. |
244| PER after 70 (from 2026) | Contributions to PER after age 70 are no longer deductible. Old PERP/Madelin may still allow deduction (Art. 163 quinvicies CGI interpretation). |
245| Micro-entreprise with high expenses | Choosing micro when actual expenses > flat abatement = paying more tax. Always compare. |
246| TVA franchise in B2B context | Not charging TVA to B2B clients offers no competitive advantage (they recover it). May lose input VAT recovery on your own costs. |
247 
248---
249 
250## Section 11 -- Annual Tax Planning Calendar
251 
252| Month | Action |
253|---|---|
254| January | Review prior year's profit. Plan PER contributions for the current year. Apply ACRE if new business. |
255| February | Gather documents: bank statements, invoices, cotisations sociales attestations, PER certificates. |
256| March | Review micro vs réel option (option must be exercised before the filing deadline for the prior year). |
257| April | File déclaration de revenus (online, typically opens mid-April). Declare PER contributions, dons, emploi à domicile. |
258| May-June | **Filing deadline** (varies by département). Finalize and submit. |
259| July | URSSAF quarterly adjustment. Review estimated cotisations vs actual. |
260| August | Mid-year profit review. Consider accelerating or deferring income/expenses. |
261| September | Review investment plans: IR-PME, FCPI/FIP before December. |
262| October | Assess PER contribution capacity. Calculate remaining deduction headroom. |
263| November | Maximize PER contributions. Make donations for the current year's réduction. Hire emploi à domicile services. |
264| December | **31 December** -- all PER contributions, dons, and investments must be made by this date. Prepay deductible expenses. Finalize invoicing strategy (defer to January if beneficial). |
