A Key Decision for Your Business
Starting a business in Slovakia is, for many entrepreneurs, associated with registering a sole proprietorship. Mainly thanks to its simplicity and minimal startup costs. It is an ideal entry point for testing a business idea and gaining initial experience. However, as the business grows, revenues increase, activities expand, or valuable assets are acquired, the requirements for the legal form of business also change. This is when it’s time to strategically reconsider whether the sole proprietorship remains optimal - or whether switching to a limited liability company (s.r.o.) would bring more long-term and significant benefits.
Choosing a business form should not be seen as a one-time, static decision made at the start, but rather as a strategic process that requires regular reassessment depending on your company’s development and ambitions. Transitioning to an s.r.o. is not only about possible tax reductions - it’s about comprehensive optimization of your business structure for future growth, better asset protection, and enhanced credibility.
5 Key Differences Between a Sole Proprietorship and an s.r.o.
1. Establishment and Administration
The process of establishing a sole proprietorship is extremely fast and simple — it often takes only one day (a few days at most) and allows you to start operating almost immediately. The initial cost is minimal — the administrative fee is only €5, and the overall administrative burden is low.
In contrast, founding an s.r.o. is a more complex and time-consuming process that requires several founding documents, such as a Deed of Foundation (for a single-member company) or Articles of Association (for multiple shareholders), as well as mandatory registration in the Commercial Register. The initial costs are higher — usually ranging from €300 to €600.
To speed up the process, it is possible to purchase a so-called “ready-made” s.r.o., which is an already established company ready for immediate takeover.
2. Legal Liability and Asset Protection
The biggest disadvantage of a sole proprietorship is unlimited liability. The entrepreneur is liable for all business obligations with all personal assets, including private property (house, car, savings), and even the property of their family. In the event of failure or damages, creditors can claim payment from any personal assets.
A limited liability company (s.r.o.), as its name implies, is liable for its obligations only up to the amount of its unpaid registered capital. This means that the personal assets of the shareholders and directors are protected and not at risk if the company encounters financial difficulties.
Switching to an s.r.o. is therefore not just about tax optimization — it is primarily about strategic risk management and protecting personal wealth. The fact that “nothing bad has happened yet” is not a guarantee that it never will. That’s why many entrepreneurs switch to an s.r.o. proactively, not reactively. It’s better to pay your accountant an extra €50 per month than to lose your home due to a contractual mistake.
3. Accounting and Administrative Burden
A sole proprietor may keep simple accounting records, tax evidence, or apply flat-rate expenses. Under the flat-rate system (60% of income, up to a maximum of €20,000 per year for 2025), the entrepreneur keeps simplified records and does not need to prove actual expenses. There is no obligation to publish financial statements in the Register of Financial Statements.
However, an s.r.o. is legally required to maintain double-entry bookkeeping, which is financially more demanding and administratively more complex. This leads to higher accounting costs and additional administrative duties, such as preparing an annual report and the obligation to publish financial statements in the public register.
4. Credibility and Business Image
While a sole proprietorship is considered a flexible form of business, it may appear less stable and less trustworthy. This can have an impact, for example, when applying for a loan or trying to cooperate with larger corporate clients, who often prefer to work with legal entities.
An s.r.o. looks more professional and trustworthy. For corporate clients, banks, and potential investors, the limited liability company is generally seen as more stable and reliable.
5. Growth Potential and Management Structure
A sole proprietorship is primarily designed for individual business activity. It cannot have partners or shareholders, and the potential to attract investors is limited. The business ends upon the entrepreneur’s death, unless the heirs decide to continue operating it.
An s.r.o. allows for a much more flexible structure — it can be established by a single person or by multiple shareholders. It can have several managing directors and partners, which allows for a better division of responsibilities and greater business continuity. The ownership interest (share) in an s.r.o. is inheritable and transferable, making it easier to sell the company or pass it on to the next generation.
Financial Comparison
The financial burden is one of the most important factors when deciding on a business form.
Switching from a sole proprietorship to an s.r.o. is financially worthwhile mainly when your annual profit (income minus expenses) exceeds approximately €30,000 to €35,000. As a self-employed person (SZČO), you pay high social and health insurance contributions on your entire tax base, whereas in an s.r.o. you can legally optimize payouts through a combination of salary and dividends.
An s.r.o. pays 15% corporate income tax on profits up to €60,000, and dividends are taxed at only 7%, without further social or health contributions. At higher profit levels, you can save hundreds or even thousands of euros per year.
Example:
With a profit of €40,000, a sole proprietor would pay approximately €12,300 in taxes and contributions, while as an s.r.o. owner you would pay around €8,400 (including both corporate tax and dividend tax), resulting in annual savings of nearly €4,000.
Our Recommendation
The decision to switch from a sole proprietorship to an s.r.o. is a major milestone in your entrepreneurial journey and requires careful evaluation of all pros and cons. A sole proprietorship is ideal for beginners, for whom simplicity, speed, and low startup costs are crucial — especially during the first year of business, when there are no social insurance contributions. It is suitable for lower income levels and for those who want to “try out” running a business first.
Transitioning to an s.r.o. is not a direct transformation, but rather the establishment of a new legal entity, followed by the termination or suspension of the sole proprietorship and the formal transfer of assets and liabilities. This process requires precise planning — and often professional assistance.
Given the complexity of tax and legal aspects, consultation with a tax advisor or accountant is highly recommended. An expert can help you calculate specific scenarios, minimize risks, and ensure a smooth transition.
