What is a Trade License and Who Needs One?

A trade license is an official authorization issued by the Trade Licensing Office (živnostenský úřad) that permits you to conduct specific business activities in the Czech Republic. The license registers your business in the Czech Trade Register, assigns you a business identification number (IČO), and integrates you into the local tax, social security, and health insurance systems.

Not all business activities require a trade license. Czech law exempts certain professions and sectors that are regulated by other specialized legislation. These include banking and financial services, legal and notarial services, medical and veterinary services, insurance activities, and mining operations. However, these exemptions do not mean these activities are unregulated—they simply require different forms of authorization under sector-specific laws.

For most commercial activities, including consulting, software development, retail trade, marketing services, and manufacturing, a trade license is mandatory. The type of license you need depends on the nature of your business.

Types of Trade Licenses in Czech Republic

Czech law distinguishes between two main categories of trade licenses: notifiable trades and concession trades.

Notifiable Trades

Notifiable trades (ohlašovací živnosti) can be obtained simply by submitting a notification to the Trade Licensing Office. You can begin your business activities immediately upon submission—you do not need to wait for approval. However, this does not mean the process is automatic or risk-free. The Trade Licensing Office will review your application and may reject it if you fail to meet the legal requirements.

Notifiable trades are further divided into three subcategories. Unqualified or "free" trades (volná živnost) are the simplest. As of 2025, there are 82 specific activities classified as free trades, including most consulting services, IT development, advertising, language instruction, and general retail trade. These require no proof of special qualifications or education.

Vocational trades (vázaná živnost) require proof of specific professional qualifications, typically documented through a relevant diploma or verified work experience in the field. Professional trades (řemeslná živnost) are craft-based activities that also require proof of technical competence or designation of a responsible representative who holds the necessary qualifications.

Concession Trades

Concession trades (koncesované živnosti) require explicit state approval before you may begin operations. These are activities considered sensitive or high-risk, such as operating a travel agency, road freight transport services, security and protection services, or handling of weapons and ammunition. The application process is more complex, and you cannot start the business until the Trade Licensing Office grants the concession.

For foreign companies, understanding which category applies to your business is not always straightforward. Business models that combine multiple activities, digital services that do not fit traditional categories, or franchise operations adapted from foreign markets may require legal analysis to determine the correct licensing path.

FAQ – Legal Tips on Trade License Types

1. Can I operate under one "free trade" license if my business includes multiple activities?

Yes, a single free trade license covers all 82 activities listed in Annex 4 of the Trade Licensing Act. However, if your business also includes activities classified as vocational, professional, or concession trades, you must obtain separate authorization for each. If you are unsure which activities your business includes, contact us at office@arws.cz. 

2. My company provides software development services. Do I need a license?

Most IT consulting and software development activities fall under free trades and require a trade license. However, if your services involve financial software, medical systems, or critical infrastructure, additional sector-specific authorizations may apply. Our lawyers are ready to assist you – email us at office@arws.cz. 

3. Can I use a trade license issued in another EU country?

EU citizens providing temporary services in the Czech Republic may rely on their home country license under certain conditions. However, if you establish a permanent business presence in the Czech Republic, you must obtain a Czech trade license. Get tailored legal solutions by writing to office@arws.cz. 

Penalties for Operating Without a License: Administrative Fines

If you conduct business activities in the Czech Republic without the required trade license, the Trade Licensing Office has the authority to impose substantial administrative fines. The amount of the fine depends on the type of trade you are conducting without authorization.

For unqualified (free) trades, the fine can reach up to CZK 500,000. For vocational or professional trades, the fine increases to CZK 750,000. For concession trades—the most heavily regulated category—the maximum fine is CZK 1,000,000.

These are not theoretical maximums. Czech authorities actively enforce trade licensing requirements through regular inspections, cross-checks with tax records, and investigations triggered by complaints from competitors or customers. In 2021, Czech authorities imposed a fine of CZK 13,945,000 on one company for unfair commercial practices and subsequently revoked its trade license for three years, effectively forcing the company to cease operations.

The Trade Licensing Office also has the power to order immediate cessation of your business activities and to block your company from conducting any operations until proper authorization is obtained. This can result in lost contracts, reputational damage with clients and business partners, and the inability to fulfill existing obligations, potentially triggering breach of contract claims against your company.

For foreign companies, these penalties are particularly severe because they can also trigger immigration consequences. Non-EU citizens holding business visas or residence permits tied to their trade license may lose their legal basis to remain in the Czech Republic if the license is revoked or suspended.

Advokátní kancelář ARROWS, an international law firm operating from Prague, European Union, provides comprehensive defense in administrative penalty proceedings before the Trade Licensing Office and Czech courts. We assist foreign clients in preparing appeals, negotiating penalty reductions, and obtaining the necessary licenses to restore business operations. 

Criminal Liability: When Does Unlicensed Business Become a Crime?

Operating without a license is not only an administrative violation—it can also constitute a criminal offense under Section 250 of the Czech Criminal Code. The offense is called "unauthorised business activity" (neoprávněné podnikání), and it applies when a person provides services or conducts business activities without the required authorization "to a greater extent."

What does "to a greater extent" mean? Czech courts interpret this element based on several factors: the duration of the unauthorized activity, the scope and systematicity of operations, the amount of revenue generated, whether the activity was intended as a permanent source of income, and whether the lack of authorization could have caused damage to customers, competitors, or the public.

The basic offense carries a penalty of imprisonment for up to two years or disqualification (a ban on conducting specific activities or holding certain positions). If the unauthorized business causes significant damage or generates significant benefit for the perpetrator, the penalty increases to imprisonment for six months to five years or a monetary penalty. For large-scale damage or benefits, the penalty can reach two to eight years of imprisonment.

Criminal prosecution for unauthorized business is not rare in the Czech Republic. Prosecutors pursue these cases actively, particularly when the unauthorized activity involves public safety risks, consumer harm, or tax evasion. Foreign entrepreneurs are not exempt—Czech criminal law applies equally to all persons conducting business on Czech territory, regardless of their nationality or residence.

The distinction between administrative violation and criminal offense is crucial but not always clear in practice. The same conduct—operating without a license—can result in both administrative fines and criminal prosecution. Whether criminal charges are filed depends on prosecutorial discretion, the extent of the violation, and the specific circumstances of the case. This dual exposure creates significant legal risk for business owners who operate without proper authorization.

Risks and Penalties	How ARROWS Helps (office@arws.cz)
Criminal investigation for unauthorized business: Risk of imprisonment, permanent criminal record, disqualification from business activities	Criminal defense representation, negotiation with prosecutors, development of defense strategy, court representation
Significant damage caused to third parties: Enhanced criminal penalties (6 months to 5 years), civil liability for damages	Legal opinions on liability exposure, damage limitation strategies, representation in civil and criminal proceedings
Large-scale unauthorized operations: Imprisonment 2 to 8 years, asset seizure, company dissolution	Emergency legal intervention, cooperation with law enforcement, regulatory negotiations, license regularization on expedited basis

Additional Enforcement Mechanisms and Consequences

Beyond administrative fines and criminal prosecution, operating without a license triggers several additional legal and financial consequences that can devastate a business.

The Czech Labour Inspection Office (Státní úřad inspekce práce) has authority to investigate whether businesses are engaging in illegal employment practices. One common violation is the "Švarc system," where a company treats employees as self-employed contractors to avoid employment obligations. If the Labour Inspection Office determines that individuals are performing dependent work without proper employment contracts, it can impose fines up to CZK 10 million on the employer. Additionally, the company may face retroactive assessments for unpaid social security contributions, health insurance premiums, and employment taxes for all improperly classified workers.

The Czech Tax Authority can also pursue companies operating without licenses for tax evasion. If you generate income from business activities without proper registration, you are not only violating licensing requirements but also tax laws. The Tax Authority can assess back taxes with penalties and interest, and in serious cases, freeze your bank accounts or initiate proceedings to dissolve the company.

For foreign companies with parent entities abroad, these enforcement actions can create international complications. Tax authorities in multiple jurisdictions may become involved, particularly if the unauthorized Czech operations affect transfer pricing, permanent establishment status, or cross-border profit allocation. Czech enforcement actions can also trigger reputational harm with foreign regulators, banks, and business partners.

Czech law also provides for corporate criminal liability. Under the Act on Criminal Liability of Legal Persons (enacted in 2011), companies themselves—not just their directors or employees—can be prosecuted and convicted of criminal offenses, including unauthorized business activity. Corporate criminal liability can result in dissolution of the company, prohibition from receiving public contracts or subsidies, and publication of the conviction, causing severe reputational damage.

Advokátní kancelář ARROWS provides integrated legal defense across all these enforcement mechanisms. We coordinate responses to inspections by multiple authorities, manage parallel administrative and criminal proceedings, and develop comprehensive strategies to resolve regulatory violations while minimizing business disruption. Thanks to our ARROWS International network built over ten years, we handle cases with cross-border elements daily and can coordinate with authorities and legal counsel in other jurisdictions when necessary.

Specific Risks for Foreign Entrepreneurs

Foreign entrepreneurs face unique vulnerabilities when establishing or operating businesses in the Czech Republic. Many of these risks arise from misunderstandings about Czech legal requirements or assumptions that business practices legal in their home countries are also permissible in the Czech Republic.

One common mistake is assuming that a business license or professional authorization obtained in another country is sufficient to operate in the Czech Republic. While EU directives provide for mutual recognition of qualifications and freedom to provide services, these principles have limits. If you establish a permanent business presence in the Czech Republic—such as an office, employees, or regular business activities—you must obtain Czech authorization regardless of licenses held elsewhere.

Another frequent error involves misunderstanding which activities require licensing. Business models common in other markets may not fit neatly into Czech licensing categories. For example, many foreign companies providing consulting services, online platforms, or franchise operations assume they do not need a trade license because their primary business is conducted remotely or the legal entity is registered abroad. However, if you have clients in the Czech Republic, employ workers here, or maintain assets or operations on Czech territory, you likely need Czech licensing.

The 15-day reporting requirement creates a particular compliance trap for foreign managers. Czech law requires that any changes to registered information—including business address, scope of activities, or responsible representatives—must be reported to the Trade Licensing Office within 15 days. Foreign executives accustomed to more flexible timelines in common-law jurisdictions often miss this deadline, resulting in fines of up to CZK 20,000 per violation. More seriously, operating with outdated or incorrect licensing information can be treated as operating without proper authorization, exposing the company to the full range of penalties discussed above.

Non-EU citizens face additional complexity. To obtain a trade license, you must hold a valid residence permit or long-term visa for the Czech Republic. The license cannot be activated until you receive immigration authorization. Furthermore, if your residence permit is tied to your business activities, any problems with your trade license—such as suspension or revocation—can jeopardize your immigration status, potentially requiring you to leave the country.

FAQ – Legal Tips for Foreign Business Owners

1. I'm an EU citizen providing temporary services in Czech Republic. Do I need a Czech trade license?

EU law allows temporary provision of services based on your home country authorization. However, "temporary" has specific legal meaning and does not cover establishing permanent operations. If you maintain a Czech office, regularly serve Czech clients, or conduct business for extended periods, Czech licensing likely applies. Potřebujete právní pomoc?

2. My company is registered in another EU country but has clients in Czech Republic. Am I operating legally?

This depends on the nature and extent of your Czech activities. Remote provision of services to Czech clients generally does not require Czech licensing. However, if you have employees, a physical presence, or conduct substantial operations on Czech territory, you need Czech authorization. 

3. What happens if I started business before obtaining the required license?

You should immediately cease operations and apply for the required license. Continuing to operate increases your liability exposure. If authorities have not yet detected the violation, obtaining proper licensing and filing corrective documents may resolve the situation with minimal penalties.

How to Obtain a Trade License: Process and Requirements

Understanding the licensing process is essential for foreign entrepreneurs establishing operations in the Czech Republic. The requirements and procedures differ depending on your citizenship status and the type of business you plan to conduct.

All applicants, regardless of nationality, must meet three general conditions. You must be at least 18 years old, have legal capacity (not under guardianship or conservatorship), and be of good character (bezúhonný). Good character is typically proven through a criminal record extract.

For EU citizens and nationals of European Economic Area countries, the process is relatively straightforward. You can apply for a trade license at any Trade Licensing Office in the Czech Republic—the office does not need to correspond to your business address or residence. You submit a standard application form, provide identification, proof of your business address in the Czech Republic, and pay an administrative fee of CZK 1,000. For free trades, no additional documents are required. For qualified trades, you must also provide proof of professional qualifications or designate a responsible representative who holds the required credentials.

For non-EU citizens, the process includes an additional requirement: you must provide proof of legal residence in the Czech Republic, such as a long-term visa or residence permit. Importantly, you can register your trade license before receiving your residence permit, but the license cannot be activated until you obtain immigration authorization. This creates a coordination challenge—you need the trade license application to support your business visa application, but you cannot legally operate the business until both the license and the visa are approved.

The Trade Licensing Office processes applications within 3 to 5 working days. For notifiable trades, you can technically begin operations immediately upon submitting your application, even before the Trade Licensing Office completes its review. However, this is risky—if the Office determines that you do not meet the requirements, it can retroactively invalidate your license, meaning all business activities you conducted were unauthorized.

After obtaining your trade license, you must complete several additional registrations. You must register with the Czech Tax Authority (unless you use a tax advisor, who will handle this automatically), notify the Czech Social Security Administration (within 8 days of starting self-employment), and register with a health insurance company (also within 8 days). Each of these registrations carries its own deadlines and penalties for non-compliance.

Ongoing Compliance Obligations After Obtaining a License

Obtaining a trade license is only the first step. Czech law imposes numerous ongoing obligations on license holders, and failure to meet these requirements can result in penalties, license suspension, or even revocation.

The most critical obligation is the 15-day reporting rule. Under Section 49 of the Trade Licensing Act, you must notify the Trade Licensing Office of any changes to the information submitted in your license application within 15 days of the change occurring. This includes changes to your name, address, business activities (adding new fields even under the same free trade license), appointed responsible representatives, or any other registered data.

Missing this 15-day deadline can result in a fine of up to CZK 20,000 for each violation. More seriously, if you operate with materially inaccurate licensing information—for example, if you move your business to a new address but continue using the old address on your license—authorities may treat this as operating without proper authorization, exposing you to the full range of penalties for unlicensed business.

You must also file annual tax returns even if your business generated no income. The deadline is 31 March following the end of the tax year (31 December for most companies), or 1 July if you engage a registered tax advisor to prepare your return. Late filing triggers penalties of up to 5% of the assessed tax. Late payment of taxes accrues interest at the Czech National Bank's repo rate plus 8 percentage points annually.

For companies subject to VAT, compliance becomes more complex. As of 1 January 2025, mandatory VAT registration triggers when your annual turnover exceeds CZK 2,000,000 over any 12 consecutive months, or immediately if turnover exceeds CZK 2,536,500 within a calendar year. VAT-registered entities must file monthly or quarterly VAT returns and control statements. Errors or late filings can result in substantial penalties.

Czech law also requires all businesses to use a Data Box (datová schránka) for official government communications. This electronic system is mandatory for companies and most self-employed persons. Documents delivered to your Data Box are legally considered delivered after 10 days, whether or not you actually check the box. Many foreign managers unfamiliar with this system miss critical deadlines because they do not monitor their Data Box regularly. This can lead to automatic fines, unfavorable default decisions in administrative proceedings, and even frozen bank accounts in serious cases.

Advokátní kancelář ARROWS provides ongoing compliance support for foreign businesses operating in Prague, European Union, including regular monitoring of your licensing status, automated deadline tracking, preparation and filing of all required notifications and returns, and immediate response to any communications from Czech authorities. This service is particularly valuable for foreign companies without Czech-speaking staff or those unfamiliar with Czech administrative procedures. 

Voluntary License Suspension and Revocation

If you need to temporarily pause your business operations, Czech law allows you to suspend your trade license. This is called přerušení živnosti. Suspension is particularly useful if you are uncertain about future business plans, need to focus on other activities temporarily, or want to avoid mandatory social security and health insurance payments during a period of inactivity.

To suspend your license, you must notify the Trade Licensing Office in advance using a standard change notification form (změnový list). The suspension is free of charge. You must specify the duration of the suspension or the date when you intend to resume operations. Importantly, you can suspend your license for an extended period—technically, you can set the resumption date as far in the future as 31 December 2099.

During the suspension period, you are not required to pay social security contributions or health insurance premiums, and you have no obligation to file tax returns unless you have taxable income from other sources. However, you cannot conduct any business activities under the suspended license. If you need to resume operations before the scheduled resumption date, you must notify the Trade Licensing Office in advance.

If you decide to permanently close your business, you must apply for revocation of your trade license (zrušení živnosti). This is also done through a change notification form submitted to the Trade Licensing Office. You can specify the revocation date, but it cannot be earlier than the date you submit the application. If you do not specify a date, the license is revoked on the date the Trade Licensing Office's decision becomes legally effective.

When revoking your license, you must notify both the Czech Social Security Administration (within 15 days) and your health insurance company (within 8 days). You must also file a final tax return covering the period up to the date of revocation. Failure to properly cancel your trade license can result in continued mandatory payments and penalties, even if you have ceased all business activities.

For non-EU citizens, license suspension or revocation can affect your residence permit if your immigration status is tied to your business activities. Before suspending or revoking a license, non-EU citizens should consult with immigration counsel to ensure they maintain legal authorization to remain in the Czech Republic.

ARROWS provides integrated business closure services, including preparation of all required notifications, coordination with tax authorities and insurance institutions, final tax return preparation, and for non-EU clients, immigration advice to ensure proper coordination between business and residence status.

FAQ – Most Common Legal Questions About Operating Without a Licence

1. I've been operating my business for several months without realizing I needed a Czech trade license. What should I do?

Stop all business operations immediately and contact legal counsel. We can assess your situation, determine what licenses you need, prepare expedited applications, and develop a strategy to minimize penalties and avoid criminal prosecution. The longer you continue operating, the greater your liability exposure. For immediate assistance, write to us at office@arws.cz. 

2. Can I be prosecuted in both Czech Republic and my home country for the same unlicensed business activity?

Potentially yes. Czech authorities can prosecute you for violations occurring on Czech territory regardless of your nationality or residence. Your home country may also have jurisdiction depending on its laws. Additionally, Czech enforcement actions can trigger tax and regulatory issues in other jurisdictions. Our lawyers are ready to assist you – email us at office@arws.cz. 

3. My competitor is operating without a license. Can I report them to authorities?

Yes. The Trade Licensing Office accepts complaints from any source and will investigate suspected violations. However, before taking this action, ensure your own business is in full compliance—filing a complaint often triggers scrutiny of all parties involved in the dispute. Spojte se s námi na office@arws.cz a získejte právní řešení na míru.

4. If I obtain a trade license now, will I still be liable for the period I operated without one?

Yes. Obtaining proper licensing does not erase liability for past violations. However, voluntary disclosure and correction often results in reduced penalties compared to discovery through inspection or complaint. We can negotiate with authorities on your behalf to minimize consequences. 

5. I have a trade license but my business activities have evolved beyond the original scope. Do I need to update my license?

Yes. If you are conducting activities not covered by your current license, you are operating partially without authorization. You must add the new activities to your license through a change notification submitted within 15 days. 

6. Can I avoid Czech licensing requirements by structuring my business through an entity in another country?

Not if you conduct business activities on Czech territory. Czech law applies based on where the activities occur, not where the legal entity is registered. Using a foreign structure may create additional complexity without reducing your Czech licensing obligations. Get tailored legal solutions by writing to office@arws.cz.
