Choosing the right legal form is one of the first important decisions when starting a company. Sole proprietorship, LLC and stock corporation differ in areas such as liability, capital, effort, and organization. This article compares the three legal forms and shows which points play a role in the decision.

The most common legal forms in Switzerland in detail

The Swiss corporate landscape offers various legal forms, which differ in their legal, tax, and organizational aspects. Each legal form brings specific characteristics that are suitable for different business models and corporate goals.

1. Sole proprietorship

The sole proprietorship represents the simplest form of business in Switzerland. This legal form is particularly suitable for independent small business owners.

Key features:

  • One natural person as sole owner

  • No legal separation between private and business assets

  • Foundation of a sole proprietorship is established as soon as business activity begins (however, commercial register entry is mandatory from CHF 100'000 annual turnover)

  • Free choice of company name with inclusion of the family name and companies already registered within the same political municipality

Advantages

The foundation of a sole proprietorship is particularly cost-effective and efficient. Only minimal start-up costs are incurred, and the entire process can be carried out quickly and easily, as the sole proprietorship already exists when business activity begins. Another significant advantage lies in the flexible decision-making processes, as the owner can make all decisions independently. Since there are no minimum capital requirements, financial entry is significantly simplified. In addition, sole proprietorships benefit from simplified bookkeeping as long as the annual turnover is below CHF 500'000, which significantly reduces the administrative burden.

Disadvantages

Unlimited personal liability with private assets represents a significant disadvantage of the sole proprietorship. The owner is liable with their entire assets for business liabilities, which means a significant personal risk. Financing options are also significantly limited, as no additional partners can be taken on, and raising capital must be done mainly via equity or loans. In addition, the potential sale of the company is often difficult, as prospective buyers often prefer another legal form. The lack of opportunity to involve other partners can limit the growth and development of the company.

Tax aspects:

  • Taxation of business profit under the owner as income from self-employment

  • AHV obligation to contribute on business income

  • MWST tax liability from CHF 100'000 annual turnover

This legal form is particularly recommended for:

  • Freelancers

  • Small service companies

  • Start-ups in the initial phase

  • Side-venture activities

2. LLC

The LLC represents a popular legal form for small and medium-sized enterprises in Switzerland. This form of company requires a minimum capital contribution of CHF 20'000, which must be fully paid up at the time of foundation.

Key features of the LLC:

  • Legally independent legal entity

  • Limited liability to the company's assets

  • At least one shareholder required

  • Originates with registration in the commercial register

  • Basically there is an accounting audit requirement (with the possibility to waive the limited audit, so-called opting-out)

Advantages:

The LLC offers a clear division between private and business assets, which is an important advantage for many entrepreneurs. The flexible design of the company structure makes it possible to adapt the organization optimally to the needs of the company. Externally, an LLC appears professional and trustworthy, which can be particularly advantageous in business transactions. In comparison to a sole proprietorship, raising capital in an LLC is significantly easier, as additional partners can be accepted or various financial instruments can be used.

Disadvantages:

The foundation and administration of an LLC is associated with higher costs than a sole proprietorship. The organizational structure is more complex than in other legal forms, which entails an increased administrative burden and requires more time for administrative tasks. Another disadvantage is the double taxation of profits and dividends, as both corporate profits and distributed dividends are taxed. However, there is the advantage that corporations are subject to a uniform (flat) tax rate. Unlike natural persons, they thus benefit from non-progressive taxation, which can have a positive effect, especially in the case of high profits – despite the overall higher complexity and formalities associated with this legal form.

3. Stock corporation

The stock corporation is the most complex legal form in Swiss corporate law. The statutory minimum capital is CHF 100'000, of which at least CHF 50'000 must be paid up at the time of foundation.

Key features of the stock corporation:

  • Legally independent legal entity

  • Limited liability to the company's assets

  • At least one shareholder required

  • Professional organizational structure with board of directors and (possible) statutory auditors

Advantages

The stock corporation enjoys a high reputation in the business world and – not least due to the high corporate capital – is perceived as a particularly trustworthy legal form. A major advantage lies in the easy transferability of shares, which significantly facilitates the tradability of corporate shares. The stock corporation also offers great flexibility in raising capital through various financing instruments such as share issues or bonds. Another significant aspect is the principle of anonymity/privacy of shareholders: In contrast to the owners of an LLC, the identity of the shareholders is not listed in the commercial register entry.

Disadvantages

The foundation and management of a stock corporation is associated with significant costs. In addition to initial start-up costs, regular administrative expenses arise which can place a burden on the budget. Complex corporate governance requirements imply additional administrative work and demand a professional organizational structure with appropriate control mechanisms. Another financial disadvantage stems from double taxation: First, corporate profit is taxed at the company level, and subsequently, the distributed dividends are also taxed under the shareholders. However, here too, the stock corporation is not subject to progressive tax rates, but to a uniform (flat) tax rate. The stock corporation is particularly suitable for growth-oriented companies with higher capital needs and the desire for professional structures.

Criteria for choosing the right legal form for your business

The selection of the optimal legal form is based on specific criteria that must be weighted individually for each company:

Business risk and scope of liability

The business risk and liability are decisive for the choice of legal form. The protection of private assets is particularly important. Industry-specific risks from product errors, defects, or accidents must be assessed. The extent of potential damages determines whether a limited liability legal form such as an LLC or a stock corporation is necessary. Insurance options must also be checked.

Capital requirements and financing

The capital requirements and financing options are crucial when choosing a company form. Starting capital and ongoing investments must be realistically estimated. Sole proprietorships can be founded without minimum capital, whereas LLC and stock corporation require minimum contributions. Access to external capital varies by legal form, with banks often showing more trust in corporations. Equity procurement differs: in sole proprietorships, it is the private funds of the owner; in corporations, it is the acceptance of new shareholders or the issuance of shares.

Tax aspects

Tax treatment varies according to the legal form and influences the financial situation of the company. In the case of sole proprietorships, profit is taxed as income, while corporations are subject to corporate income tax. Sole proprietors must bear social security contributions alone, whereas they are split in corporations. For VAT, there are no major differences, but administrative requirements may vary. A careful analysis of tax consequences is essential.

Administrative requirements

Administrative obligations vary by legal form. Corporations like stock corporation and LLC have more extensive bookkeeping obligations than sole proprietorships. Small sole proprietorships with turnover under CHF 500'000 can use simplified bookkeeping, while stock corporation and LLC must maintain regular bookkeeping according to the Code of Obligations. The audit requirement mainly applies to corporations, but can be waived under certain conditions; sole proprietorships are exempt. Commercial registration is mandatory for stock corporation and LLC, while sole proprietorships are subject to registration from CHF 100'000 turnover. These requirements influence the administrative burden and costs.

Corporate structure

The number of business partners significantly influences decision-making processes in the corporation. More partners mean more complex processes, which is why clear structures are required. Early succession planning secures the survival of the corporation, taking into account legal and tax aspects.

These criteria should be carefully analyzed in coordination with qualified legal advisors to make an informed decision on the appropriate legal form.

Flexibility and growth opportunities with different legal forms

The choice of legal form directly influences the growth options of your business. Each legal form offers different options for corporate development:

Sole proprietorship

  • Limited growth opportunities due to personal structure

  • Difficult access to debt capital

  • Complex transformation into a corporation during expansion

LLC

  • Flexible adjustment of shareholder structure

  • Easy capital increase possible

  • Uncomplicated transformation into a stock corporation with growth

Stock corporation

  • Maximum flexibility in raising capital

  • Broad possibilities for shareholding models

  • Optimal structure for international expansion

The stock corporation offers the greatest growth prospects through:

  • Option of going public

  • Attractiveness for investors

  • Professional external perception


The LLC represents a balanced compromise – it enables substantial growth with manageable administrative effort. For start-ups and innovative companies with growth ambitions, early selection of a stock corporation is recommended.
