Changing the business activities of an LLC no longer has to mean running around offices. In this guide we will show you how to handle the entire change process online and fully in compliance with the applicable legal regulations. For this you will need a qualified electronic signature (QES) and a qualified time stamp.
The legal definition of business is contained in the provision of Section 2 of Act No. 513/1991 Coll., the Commercial Code, as currently in force (hereinafter the “Commercial Code”). Under this provision, business is an activity carried out by an entrepreneur on a continuous basis, independently, in their own name and at their own responsibility. The fundamental element is the purpose of the business, which is to achieve a profit.
The activities an entrepreneur carries out in operating their business are referred to as business activities or as trades and are listed in the annexes to Act No. 455/1991 Coll. on trade licensing (the Trade Licensing Act).
Important information:
Every change to the business activities – expanding or narrowing them – must first be reflected in the founding documents of the limited liability company and adopted in the manner prescribed by law. At the end of this process, the change must be registered in the Commercial Register of the Slovak Republic (CRSR).
When Is It Necessary to Change Your Business Activities?
Expanding or narrowing your business activities always depends on the entrepreneur’s decision.
In practice, these changes occur mainly in the following cases:
Notice:
As entrepreneurs, you must not carry out a business activity that you do not have registered in the Commercial Register of the Slovak Republic. This constitutes unauthorized (so-called illegal) business. In practice, it sometimes happens that an entrepreneur, in the heat of their zeal and enthusiasm, begins to carry out an activity that they do not yet have registered. In such a case, the new business activity must be added and registered as soon as possible.
The administrative process for changing business activities is governed by law and can be divided into two consecutive parts:

Step 1: Decision of the Company’s Bodies – the Sole Partner Exercising the Powers of the General Meeting / Several Partners at the General Meeting
Every change to the business activities must be approved and adopted by the company’s partners.
Tip:
In one step you can delete or add one or more business activities. The law neither prescribes nor in any way limits their number. The exception is the simplified establishment of an LLC, which is carried out electronically. In this case, the number of trades in the form is limited to 15 and you can add only free trades to the company.
Step 2: Reporting the Change of Business Activities (Trades) to the Relevant Authorities
Free, regulated and skilled trades (business activities) are reported in two consecutive steps:
Important notice:
Changes to business activities must be reported within 15 days from the day the change is adopted by the company’s bodies.
The entire process takes several working days, but in rare cases it may stretch to several weeks. These situations are usually caused by the technical or staffing capacities at the relevant authorities.
When preparing the documents, watch out in particular for the following:
At the end of the entire process, you have one more obligation, which is to notify the changed data to your business partners, suppliers and customers so that they can take the adopted changes into account in your mutual cooperation and in invoicing.
