Sole Proprietorship, LLC or Stock Corporation? Comparison

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 company in Switzerland. This legal form is particularly suitable for self-employed small business owners.

Key features:

  • A natural person as sole owner

  • No legal separation between private and business assets

  • Establishment of a sole proprietorship as of the start of business activity (however, entry in the commercial register is mandatory from CHF 100'000 annual turnover)

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

Advantages

Setting up a sole proprietorship is particularly cost-effective and efficient. There are only minimal formation costs, and the entire process can be carried out quickly and easily, as the sole proprietorship exists from the moment business activity begins. Another major advantage lies in the flexible decision-making processes, as the owner can make all decisions independently. Since there are no minimum capital requirements, the 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 major disadvantage of a sole proprietorship. The owner is liable with all of his or her assets for business liabilities, which represents a significant personal risk. Financing options are also significantly limited, as no additional partners can be admitted and capital must be raised mainly through equity or loans. In addition, a possible sale of the company is often difficult, as potential buyers often prefer a different legal form. The lack of opportunity for other partners to participate can limit the growth and development of the company.

Tax aspects:

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

  • AHV obligation on business income

  • MWST obligation from CHF 100'000 annual turnover

This legal form is particularly recommended for:

  • Freelancers

  • Small service companies

  • Start-ups in the initial phase

  • Secondary occupations

2. LLC (GmbH)

The LLC represents a popular legal form for small and medium-sized enterprises in Switzerland. This corporate form requires a minimum capital contribution of CHF 20'000, which must be fully paid in upon formation.

Key features of the LLC:

  • Legally independent legal entity

  • Limited liability to the company's assets

  • At least one partner required

  • Creation upon entry in the commercial register

  • In principle, there is an auditing obligation (with the option to waive the limited audit, so-called opting-out)

Advantages:

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

Disadvantages:

Setting up and managing an LLC is associated with higher costs than a sole proprietorship. The organizational structure is more complex than other legal forms, which entails increased administrative effort and requires more time for administrative tasks. Another disadvantage is double taxation, as both company profit and distributed dividends are taxed. However, the advantage is that corporations are subject to a uniform (flat) tax rate. Unlike natural persons, they 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 (AG)

The stock corporation is the most complex legal form in Swiss company law. The legally required minimum capital is CHF 100'000, of which at least CHF 50'000 must be paid in upon formation.

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 (any) auditing body

Advantages

The stock corporation enjoys a high reputation in the business world and - not least because of the high share capital - is perceived as a particularly trustworthy corporate form. A key 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 of shareholders: in contrast to the owners of an LLC, the identity of the shareholders is not published in the commercial register entry.

Disadvantages

Setting up and running a stock corporation is associated with significant costs. In addition to initial formation costs, regular administrative expenses are incurred, which can weigh on the budget. The complex corporate governance requirements mean additional administrative effort and require a professional organizational structure with corresponding control mechanisms. Another financial disadvantage arises from double taxation: first, corporate profit is taxed at the company level, and subsequently, the distributed dividends are also taxed at the shareholder level. However, here too, the stock corporation is not subject to a progressive tax, but to a uniform (flat) tax rate. The stock corporation is particularly suitable for growth-oriented companies with higher capital requirements and the desire for professional structures.

Criteria for choosing the right legal form for your company

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

Business risk and scope of liability

Business risk and liability are decisive for the choice of legal form. Protecting private assets is particularly important. Industry-specific risks due to product defects, deficiencies or accidents must be assessed. The amount of potential damage determines whether a legal form with limited liability such as an LLC or stock corporation is necessary. Insurance options must also be examined.

Capital requirement and financing

Capital requirements and financing options are crucial when choosing the form of company. Starting capital and ongoing investments must be realistically estimated. Sole proprietorships can be formed without minimum capital, while LLCs and stock corporations require minimum contributions. Access to external capital varies depending on the legal form; banks often show more confidence in corporations. Raising equity capital is different: in the case of a sole proprietorship, it is the owner's private funds, in the case of corporations, it is the admission of new partners or the issue of shares.

Tax aspects

Tax treatment varies depending on the legal form and influences the financial position of the company. In sole proprietorships, profit is taxed as income, while corporations are subject to profit tax. Sole proprietors must bear social security contributions alone, whereas they are split in corporations. There are no major differences in value-added tax, but administrative requirements may vary. A careful analysis of the tax consequences is essential.

Administrative requirements

Administrative obligations vary depending on the legal form. Corporations such as stock corporations and LLCs have more extensive accounting obligations than sole proprietorships. Small sole proprietorships with a turnover below CHF 500'000 can use simplified bookkeeping, while stock corporations and LLCs must keep proper books under the Code of Obligations. Auditing requirements mainly affect corporations, but can be waived under certain conditions; sole proprietorships are exempt. Registration in the commercial register is mandatory for stock corporations and LLCs; sole proprietorships are subject to registration from a turnover of CHF 100'000. These requirements influence administrative effort and costs.

Corporate structure

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

These criteria should be carefully analyzed in coordination with qualified legal advisors in order to make a well-founded decision for the appropriate legal form.

Flexibility and growth opportunities with different legal forms

The choice of legal form directly influences your company's growth opportunities. Each legal form offers different options for company development:

Sole proprietorship

  • Limited growth opportunities due to personal structure

  • More difficult access to debt capital

  • Complex conversion into a corporation during expansion

LLC

  • Flexible adjustment of partner structure

  • Simple capital increase possible

  • Uncomplicated conversion into a stock corporation during growth

Stock corporation

  • Maximum flexibility in raising capital

  • Broad opportunities for participation models

  • Optimal structure for international expansion

The stock corporation offers the greatest growth prospects through:

  • IPO option

  • Attractiveness for investors

  • Professional external perception


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