An average daily rate of 500 euros per day does not yield the same income at the end of the month depending on whether you operate as a micro-entrepreneur, in a SASU, or under salary portage. The gap can exceed several hundred euros monthly, with strictly identical billing days. This discrepancy is due to three distinct mechanisms: the method of calculating social contributions, the tax base, and the level of social protection included in each status.
Social Contributions: The Factor That Widens the Gap Between Freelance Statuses
The daily rate sets a selling price. This price only becomes income after deducting mandatory contributions, and this is where the statuses diverge radically.
In a micro-entrepreneurship, contributions are calculated on gross revenue, with no deduction for professional expenses. Since January 1, 2025, the overall rate for micro-entrepreneurs in BNC (general regime) reaches 24.6% of revenue, compared to 21.1% before July 2024. This increase, spread over three years by decree, will continue in 2026.
A freelancer who bills the same daily rate as in 2023 thus sees their net income decrease mechanically, without having changed anything in their activity. The differences between salary portage rate calculation and the traditional freelance daily rate illustrate this phenomenon well: at the same rate, the deductions do not apply to the same base.
In a SASU or EURL, contributions are based on the remuneration that the manager pays themselves, not on total revenue. The company can deduct its actual expenses (equipment, subscriptions, accounting, travel) before determining the contribution base. The deduction rate is often higher in nominal value, but it applies to a narrower base.
In salary portage, the mechanism is even different: the portage company deducts management fees (usually a percentage of revenue), then calculates a gross salary on which standard employee social contributions apply, identical to those of an employee.
Micro-Entrepreneurship Caps and High Daily Rates: The Trap of the Tax Regime
For the period 2026-2028, the caps for the micro-entrepreneur regime are set at 83,600 euros for service provision and liberal activities. This increase allows more freelancers to remain in micro status with relatively high daily rates.
The paradox is as follows: staying in micro status with a comfortable daily rate seems advantageous on paper (administrative simplicity, no complete accounting). In practice, the combination of a raised cap and rising contributions creates a scissors effect. The freelancer bills more, remains eligible for the simplified regime, but retains a proportionally reduced share of their revenue.
Conversely, an independent contractor in a company who exceeds these caps without difficulty can optimize their remuneration by balancing salary and dividends (in SASU) or between management remuneration and profit distribution (in EURL under corporate tax). This latitude for arbitration simply does not exist in micro-entrepreneurship, where the entirety of the revenue constitutes the deduction base.
Salary Portage, SASU, and Micro: Comparison of Net Income at Identical Daily Rates
To make the comparison concrete, here are the deduction items that apply in each status before arriving at the disposable income:
- Micro-entrepreneur BNC: social contributions on revenue (24.6% in 2025), flat-rate deduction for income tax, no deduction for actual expenses. The net represents the lowest fraction of the billed daily rate among the three statuses.
- SASU under corporate tax: deductible professional expenses, contributions on the remuneration paid, possibility of paying out dividends (subject to flat tax or scale). The net heavily depends on the chosen remuneration strategy, but the floor is significantly higher than in micro status at equivalent revenue.
- Salary portage: management fees from the portage company (variable depending on the providers), then standard employee and employer contributions. The overall deduction rate is the highest, but it includes comprehensive social coverage (unemployment, supplementary retirement, health insurance, provident insurance).
Salary portage leaves the lowest net income of the three options at equal daily rates. In return, it offers the widest safety net: the right to unemployment at the end of a mission radically changes the calculation over several years.
Social Protection and Non-Billed Days: What the Daily Rate Doesn’t Tell You
Comparing statuses based solely on monthly net income ignores two variables that weigh heavily on actual annual income.
Days Actually Billed in the Year
A traditional employee works about 218 days per year (excluding paid leave, public holidays, RTT). A freelancer has no guarantee of billing as much. Inter-contract periods, business prospecting, administrative management, unpaid leave, sick leave without compensation: all of this reduces the number of days actually billed.
The daily rate is a unit price, not a guaranteed income. Two freelancers with the same daily rate but different occupancy rates will have very different annual incomes, regardless of their status.
Coverage in Case of Activity Cessation
In micro-entrepreneurship and SASU, there is no right to unemployment in case of client loss. Salary portage, because it relies on an employment contract, opens rights to unemployment insurance under certain conditions. Over a freelance career punctuated by inter-contracts, this difference can represent several months of income.
Retirement constitutes another blind spot. The retirement contributions of a micro-entrepreneur generate rights significantly lower than those of a ported employee or a SASU manager who pays themselves a regular salary. At the same daily rate, the micro-entrepreneur prepares for a weaker retirement than their counterparts in companies or salary portage.
The choice of status is not just about increasing immediate net income. A daily rate of 500 euros can yield a comfortable monthly income in SASU with good optimization, an average income in micro that is eroded by rising contributions, or a more modest income in portage that finances comprehensive social security.
The right arbitration depends on the number of billed days you can realistically achieve and the level of risk you are willing to bear without a safety net.
