Section 1 -- Quick Reference

Quick Reference

Field	Value
Country	France (République française)
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)
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.

Income Tax Rates 2026 (Barème progressif)

Income Tax Rates 2026 (Barème progressif)

Tranche	Taxable income per part (EUR)	Rate
1	0 -- 11,497	0%
2	11,498 -- 29,315	11%
3	29,316 -- 83,823	30%
4	83,824 -- 180,294	41%
5	180,295+	45%

Income 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.

Section 2 -- Income Splitting & Structuring

Micro-Entreprise vs Régime Réel

Micro-Entreprise vs Régime Réel

Factor	Micro-Entreprise (micro-BIC / micro-BNC)	Régime Réel
Turnover ceiling (2026)	EUR 77,700 (services/BNC) / EUR 188,700 (goods/BIC)	No limit
Taxation method	Flat abatement: 34% (BNC) or 50% (BIC services) or 71% (BIC goods)	Actual expenses deducted
When to choose réel	When actual deductible expenses exceed the flat abatement	Always compare before choosing
Social contributions	Based on turnover (micro) vs net profit (réel)	Réel may be lower if expenses are high

Legislation — CGI Art. 50-0 (micro-BIC), Art. 102 ter (micro-BNC) (CGI Art. 50-0, Art. 102 ter)

Quotient Familial (Family Splitting)

Quotient Familial (Family Splitting)

Parts	Family situation
1	Single, no children
2	Married/PACS, no children
2.5	Married/PACS, 1 child
3	Married/PACS, 2 children
4	Married/PACS, 3 children (1 full part from 3rd child)

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). (CGI Art. 193-197)
Legislation — CGI Art. 193-197 (CGI Art. 193-197)

EURL/SARL vs Entreprise Individuelle

EURL/SARL vs Entreprise Individuelle

Factor	Entreprise Individuelle	EURL/SARL (IS option)
Top marginal rate	45% + social charges (~45%)	IS: 15% (up to EUR 42,500) / 25% above
When to consider	For simplicity and lower income	When profits exceed ~EUR 60,000 and can be retained
Rémunération du gérant	N/A	Salary deductible from company profit, taxed as income for gérant

Section 3 -- Deductions Most People Miss

Deductions Most People Miss

Deduction	Legislation	Notes
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.
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.
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.
Home office (local professionnel)	CGI Art. 39, Art. 93	Proportion of rent, utilities, insurance for dedicated professional space. Calculate by floor area ratio.
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).
Cotisations professionnelles	CGI Art. 93	Ordres professionnels, syndicats, associations professionnelles.
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).
Intérêts d'emprunt	CGI Art. 39-1-1°	Interest on loans taken for professional purposes is deductible.
Assurances professionnelles	CGI Art. 39, Art. 93	RC Pro, prévoyance complémentaire Madelin (within limits), multirisque professionnelle.
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.

Section 4 -- Capital Allowances Optimization

Legislation — CGI Art. 39 (amortissements), Art. 39 A (dégressif) (CGI Art. 39, Art. 39 A)

Amortissement Linéaire (Straight-Line) vs Dégressif (Declining Balance)

Amortissement Linéaire (Straight-Line) vs Dégressif (Declining Balance)

Method	When to use	Coefficient (for assets with useful life ≥ 3 years)
Linéaire	Default method, equal annual deductions	N/A
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

Timing of Purchases

Timing of Purchases — Under 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. (CGI Art. 39 A)

Low-Value Assets

Low-Value Assets — Assets under EUR 500 HT can be immediately expensed without depreciation (tolérance administrative). Above EUR 500 HT, depreciation is required. (tolérance administrative)

Suramortissement (Super-Depreciation)

Suramortissement — Certain 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. (CGI Art. 39 decies and following)

Section 5 -- Loss Utilization

Legislation — CGI Art. 156 I, Art. 156 I bis (CGI Art. 156 I, Art. 156 I bis)

Loss Utilization table

Relief	Detail	Limit
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
Carry-forward	Unused deficit is carried forward for 6 years against profits of the same category	6-year limit
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
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

Strategy

If 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.

Section 6 -- Timing Strategies

Timing Strategies

Strategy	Detail
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.
Accelerate expenses	Prepay deductible expenses (insurance, subscriptions, training) before 31 December. Under BNC déclaration contrôlée, expenses are deductible when paid.
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.
Quotient familial optimization	Declare PACS or marry before 31 December to benefit from joint taxation for the entire year.
Versement libératoire timing	Under micro, the versement libératoire (flat tax on turnover) is monthly or quarterly. Manage cash flow around payment dates.
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.

Section 7 -- VAT Optimization (TVA)

Legislation — CGI Art. 293 B (franchise en base), Art. 302 septies A (régime simplifié) (CGI Art. 293 B, Art. 302 septies A)

VAT Optimization (TVA) table

Strategy	Detail
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.
Opt for TVA	If significant input TVA (investment phase), opt to charge TVA to recover inputs. Lock-in: 2 calendar years.
Régime simplifié	Annual TVA return with 2 quarterly acomptes. Available if turnover < EUR 840,000 (goods) / EUR 254,000 (services).
TVA sur les débits vs encaissements	For service providers: TVA on encaissements (payment received) defers TVA liability vs. débits (invoice date).
Autoliquidation (reverse charge)	For intra-EU B2B services: no French TVA charged. Report via DES/DEB.

Section 8 -- Social Security Optimization

Legislation — Code de la Sécurité Sociale; Loi de financement de la Sécurité sociale 2026 (Code de la Sécurité Sociale; Loi de financement de la Sécurité sociale 2026)

Cotisations Sociales Structure (Travailleurs Non-Salariés / TNS)

Cotisations Sociales Structure (Travailleurs Non-Salariés / TNS)

Contribution	Rate (approximate)	Base
Assurance maladie-maternité	0-6.5% (progressive)	Net profit
Allocations familiales	0-3.1% (progressive)	Net profit
Retraite de base (CNAV)	17.75% up to PASS; 0.6% above	Net profit
Retraite complémentaire (RCI)	7-8% up to 4× PASS	Net profit
Invalidité-décès	1.3%	Net profit
CSG/CRDS	9.7%	Revenue + cotisations
CFP (formation)	0.25% of PASS	Flat contribution
Total effective rate	~40-45% of net profit

Optimization Strategies

Optimization Strategies

Strategy	Detail
ACRE (first year)	50% reduction in social contributions for the first year of business creation. Automatic for micro-entrepreneurs since 2020.
Micro vs réel social base	Under micro, social contributions are calculated on turnover (after flat abatement). Under réel, on net profit. Compare both.
Cotisation minimale	Below a minimum profit level, minimum contributions apply. In a loss year, you still pay minimum health/retirement contributions.
Conjoint collaborateur	A spouse working in the business without salary can be registered as conjoint collaborateur for social coverage at reduced cost.
PER contributions as social deduction	PER Madelin/154 bis contributions reduce the social contribution base for TNS if deducted from BIC/BNC profit.

Section 9 -- Investment & Retirement

Plan d'Épargne Retraite (PER) -- CGI Art. 163 quatervicies / Art. 154 bis

Plan d'Épargne Retraite (PER) (CGI Art. 163 quatervicies / Art. 154 bis)

Feature	Detail
PER individuel (salarié/particulier)	Deductible contributions up to 10% of net taxable income, max EUR 38,448 (2026) or EUR 4,806 minimum
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).
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.
Carry-forward of unused allowance	Now 5 years (extended from 3 years by Loi de Finances 2026). Spouse pooling maintained.
Exit taxation	Capital: IR + social charges (18.6% in 2026). Annuity: IR + social charges.
Age limit (from 2026)	Contributions after age 70 are no longer deductible for PER (not applicable to old PERP/Madelin).
Non-deduction option	At TMI 0% or 11%, opt for non-deduction: no tax benefit at entry, but tax-free capital at exit.

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.

Assurance-Vie

Assurance-Vie

Feature	Detail
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).
No deduction at entry	Not deductible from income tax. But tax-efficient for long-term savings and estate planning.
Succession	Up to EUR 152,500 per beneficiary tax-free if funded before age 70.

Réductions d'Impôt (Tax Credits/Reductions)

Réductions d'Impôt (Tax Credits/Reductions)

Reduction	Rate	Cap	Legislation
Emploi à domicile	50%	EUR 12,000/year (+EUR 1,500/dependent, max EUR 15,000)	CGI Art. 199 sexdecies
Dons aux œuvres	66% (general) / 75% (Coluche)	20% of taxable income / EUR 1,000	CGI Art. 200

Crédit d'impôt formation dirigeant	~EUR 878 (2026) for TPE	Forfait annuel	CGI Art. 244 quater M
Plafonnement global des niches	EUR 10,000/year	All reductions combined	CGI Art. 200-0 A

Section 10 -- Red Lines

Red Lines

Risk	Detail
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.
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.
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.
Non-professional activities	Losses from non-professional BIC/BNC cannot offset other income. If activity is non-professional, loss utilization is severely limited.
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).
Micro-entreprise with high expenses	Choosing micro when actual expenses > flat abatement = paying more tax. Always compare.
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.
