The verdict in three sentences
For an online business in 2026, a sole proprietorship works while revenue stays low and risk is limited. Once you pass 5 million FCFA in annual revenue or take on inventory and staff, a SARL (limited company) protects your assets and reassures banks and suppliers. The SAS remains reserved for fundraising projects or multiple partners needing flexible governance.
Comparing the three structures
The choice isn't only about setup cost, but about liability, taxation, and credibility.
| Criterion | Sole proprietorship | SARL | SAS |
|---|---|---|---|
| 2026 setup cost | 25,000-40,000 FCFA | 60,000-100,000 FCFA | 90,000-150,000 FCFA |
| Liability | Unlimited | Limited to contributions | Limited to contributions |
| Minimum capital | None | 100,000 FCFA | Free |
| Banking credibility | Low | Good | Very good |
| Scalability (partners) | Low | Medium | High |
The unlimited liability of a sole proprietorship is the most underestimated point: in case of debt, your personal assets (home, vehicle) can be seized. A SARL or SAS ring-fences that risk.
The tax switchover threshold
When should you change structure? Taxation gives a clear signal.
| Annual revenue | Recommended structure | Indicative tax regime |
|---|---|---|
| < 3M FCFA | Sole proprietorship | Flat rate / simplified |
| 3-5M FCFA | Sole prop. or SARL | Simplified actual |
| 5-25M FCFA | SARL | Actual, corp. tax 25-30% |
| > 25M FCFA | SARL or SAS | Actual, corp. tax + VAT |
Above 5 million FCFA in revenue, staying a sole proprietor often means less optimized personal taxation and blocks access to credit. That's the natural moment to switch.
Mini case study
Ibrahim, a freelance developer in Dakar, invoices 4.5 million FCFA/year as a sole proprietor. A large corporate client demands an invoice with a trade registry number and VAT he can't issue: he loses a 2 million FCFA contract. Switching to a single-member SARL (80,000 FCFA), he wins that contract, protects his assets, and deducts expenses under the actual regime. The return is immediate: 80,000 FCFA spent against 2 million FCFA of revenue recovered.

FAQ
At what revenue should I switch to a SARL?
As a 2026 order of magnitude, switching becomes worthwhile above 5 million FCFA in annual revenue, or earlier if you take on inventory, staff, or supplier debt.
Does a sole proprietorship protect my assets?
No. Liability is unlimited: your personal assets can be seized in case of debt. This is the main reason to switch to a SARL.
Is an SAS useful for a solo entrepreneur?
Rarely. The SAS shines for raising funds or hosting several partners with flexible governance; for a solo, the SARL is simpler and cheaper.
What is the corporate tax rate in 2026?
Corporate tax sits around 25 to 30% depending on the WAEMU-zone country. A sole proprietorship is taxed on the owner's personal income, often less optimized at high revenue.
Can I change structure later?
Yes, converting a sole proprietorship into a SARL is possible but involves procedures and costs. It's better to anticipate as soon as growth is confirmed.
