Legal forms in Belgium: SRL, SA, SC, ASBL — which one to pick in 2026?

In brief

In 2026, the vast majority of Belgian SMEs choose the SRL: no legal minimum capital, liability limited to contributions, and corporate tax of 20% on the first 100,000 euros of profit. The SA remains reserved for capital-intensive projects or fundraising rounds, the SC for collective projects, and the ASBL for non-commercial activities. A freelancer earning more than 35,000 euros net annually generally benefits from incorporating an SRL rather than remaining a sole trader.

The 2026 landscape

Since the Belgian Code of Companies and Associations (CCA) entered into force in 2019-2020, the landscape has been streamlined. The old SCRL, SPRL, SCS, SCA have disappeared or been reshuffled. In 2026, the realistic choices for a business activity are:

Natural person: sole trader

For whom. Side activity, doctor, lawyer, solo consultant whose revenue stays < €60-80k/year.

Pros.

• No starting capital

• Simplified accounting (cash basis if revenue < €750k)

• Setup in 1-2 weeks via an accredited business desk

Cons.

• Unlimited liability on personal assets (save the unseizable principal residence declaration, possible since 2019)

• Tax: progressive personal income tax (IPP) up to 50%

• Less solid B2B image for large clients

To check before switching to SRL: net annual income > €35-40k after social contributions — beyond that, the SRL becomes more tax-efficient in most cases.

SRL: the Belgian standard

The Limited Liability Company replaced the SPRL in 2019. It's the default for 80% of Belgian SMEs.

Pros.

• Free starting capital — the "minimum capital" concept disappeared (the former €18,550 threshold no longer exists). But the initial financial plan must be realistic, otherwise the founders' liability is engaged in case of bankruptcy within 3 years.

• Liability limited to contributions — your personal assets are protected (save personal guarantees given to banks)

• Statutory flexibility — possibility to define multiple voting shares, preferred shares, controlled transfers

• Corporate tax (ISOC): 20% on the first €100,000 of profits (under conditions), 25% beyond — often more favorable than personal income tax beyond a certain income

Cons.

• Mandatory double-entry accounting (PCMN chart)

• Annual financial statements filed with the NBB (publication = public data)

• Recurring costs (accountant, general meeting, publication)

The 3-year financial plan: underestimated by many founders. Must present a plausible working capital, quantified revenue assumptions, and coherent equity. A Belgian certified accountant co-signs; their quality personally protects the founders.

SA: to raise and structure

The Public Limited Company keeps its role when the project targets:

• Fundraising from external investors

• Listing or a long-term transmission project

• Beefed-up governance (multi-member board, statutory auditor required above thresholds)

Minimum capital: €61,500 (fully paid up at incorporation). Easy share transfers. Higher structural cost than SRL.

For whom. Seed/Series A startup, patrimonial holding, business acquisition project.

SC: the collective project

The Cooperative Society is designed for a project where collective and solidarity matter as much as profitability: agricultural co-op, citizen energy co-op, cooperative shop.

Features.

• Minimum 3 founders

• Variable capital (smooth entries/exits)

• "One person = one vote" principle (or limited weighting)

• Possibility of CNC (National Cooperative Council) accreditation for favorable taxation on dividends

For whom. Any activity where collective governance is central.

ASBL: the non-profit

The Non-profit Association is meant for non-commercial activities: sport, culture, social, education, research.

Key CCA rules for ASBLs:

• At least 2 founders

• Disinterested purpose — possibility to run commercial activities accessory to the association's purpose

• No profit distribution to members

• Simplified accounting if "small ASBL" (3 criteria on revenue, balance sheet total, FTE)

• Separate legal entity, limited liability

Do NOT confuse: ASBL ≠ tax exemption. An ASBL running a routine commercial activity may be subject to ISOC. The ASBL status isn't a magic tax shield.

Tax comparison — worked example

A freelancer with €80,000 of net annual profit:

Natural person:

• Marginal personal income tax: ~50% above €46,440

• INASTI social contributions: ~20.5%

• Estimated take-home: ~€36,000

SRL with €45,000 salary + dividend of the post-ISOC remainder:

• ISOC on (80,000 - 45,000) = 35,000 × 20% = €7,000

• Salary 45,000 → personal income tax around €15,500

• Dividend (35,000 - 7,000) = €28,000 → withholding 30% = €8,400

• Estimated total take-home: ~€49,100

Difference: ~€13,000 net/year in favor of the SRL, *all else equal*. The real calculation depends on family situation, deductible expenses, use of VVPR-bis (15% withholding under conditions), etc.

How Company Belgium helps

To understand what the BCE/KBO register is before registering, read our complete guide to the BCE/KBO. The full incorporation steps are detailed in our guide to starting a business in Belgium 2026. If your activity is cross-border, our article on doing business across borders from Belgium covers the VAT implications and the right structure to adopt. For NACE codes linked to your legal form, see our article on understanding NACE codes in Belgium. Finally, Belgian company statistics by legal form are available in our Belgian company statistics 2026 overview.

When creating your company record in the CRM or Clients module, you enter the BCE number — the legal form is automatically pulled from the BCE and displayed. The Invoicing module then adapts:

• Mandatory legal mentions on invoices (BCE number, capital for SA, "RPM Brussels" mention for a Brussels SRL)

• The contract template (non-compete clause, mandate duration for SA directors)

• The required UBO structure in the AML module

If you support clients with company formation (fiduciaries, lawyers), the integrated tax simulator compares in real time the IPP vs ISOC scenarios on the client's forecast figures.

The common-sense rule

Don't pick a legal form because "that's what everyone takes". The real criterion is:

How much do I risk? → if > €30-50k engagement, SRL minimum

What's my tax target? → IPP profitable up to ~€50k net, SRL beyond

Will I partner up or raise? → SRL with shareholders' agreement; SA if high ambition

Is my activity commercial? → if not, ASBL (with its own constraints)

Three quarters of Belgian SMEs end up in SRL. The remaining quarter has a concrete reason. Identify yours, otherwise: SRL.
