Mistakes when registering as a sole trader in Slovakia

27.09.2026

Registration of a sole proprietorship in Slovakia is usually completed relatively quickly and without complicated bureaucratic procedures. However, after starting their business activities, many entrepreneurs encounter unexpected difficulties. Most often, these problems are related to a lack of knowledge of tax rules, mandatory payments, and business requirements.
 

Incorrectly chosen business activities


During registration, entrepreneurs often list too many types of activities «for the future» or fail to add services they actually plan to provide. This may later lead to questions from government authorities and create difficulties when working with clients or partners.
 

Ignoring mandatory expenses


After registering as a sole proprietor, you must pay health insurance contributions. Social insurance contributions are assessed later — based on the level of income for the previous period. Many people fail to plan for these expenses in advance, which can lead to a lack of funds and financial strain.
 

Lack of proper financial record-keeping


Some entrepreneurs do not keep documents confirming their expenses: receipts, invoices, and payment slips. As a result, it becomes impossible to properly account for expenses and reduce the taxable base, which can lead to overpayment of taxes.
 

Working without written contracts


Working solely on the basis of verbal agreements often leads to conflicts. In the event of delayed payment, disputes, or tax inspections, the absence of signed documents can create serious problems.
 

Mixing personal and business money


Using the same account for personal expenses and business activities is formally permitted, but in practice it significantly complicates accounting. A separate bank account helps to better control the flow of funds and simplifies record-keeping.
 

Late filing of reports


Beginning entrepreneurs often forget the deadlines for filing tax returns or make mistakes in their documents. This may result in fines, additional inspections, and the need to resubmit reports.
 

Using a sole proprietorship instead of official employment


Sometimes a sole proprietorship is established for work under a scheme that is, in practice, similar to regular employment. If the relevant authorities establish signs of an employment relationship, this may be considered a violation of the law.
