Liability Insurance for the Self-Employed: A Complete Guide for 2026

As a self-employed person (OSVČ), you bear full personal liability for any damages you cause in the course of your business activities. Unlike employees, whose liability to their employer is capped at 4.5 times their average monthly earnings, the self-employed are liable with their entire assets — personal and business alike — with no upper limit. Liability insurance is therefore one of the most important tools for protecting both your business and your personal finances.

In this article, we'll look at when liability insurance is mandatory, what types are available, exactly what it covers, how much it costs, and how to choose the right option for your business.

Why Liability Insurance Matters for the Self-Employed

Imagine this: you're a tradesperson and you accidentally damage an expensive piece of furniture while working at a client's home. Or you're an IT consultant and a misconfiguration you made causes a client's e-shop to go offline for an entire weekend. Or perhaps you're an accountant and a mistake on your part results in your client receiving a penalty from the tax authority.

In all of these situations, as a self-employed person you are fully liable for the damage caused. Without liability insurance, you'd have to cover everything out of your own pocket — and in some cases that can mean amounts running into hundreds of thousands or even millions of crowns.

Key Reasons to Have Liability Insurance

• Protection of personal assets — in the event of a claim, you won't have to dip into your savings or sell property
• Professional credibility — insurance shows clients that you run your business responsibly
• Contractual requirement — many companies require proof of liability insurance as a condition of working together
• Peace of mind — you can focus on your work without worrying about financially devastating events
• Legal cost coverage — insurance typically covers the costs of legal representation as well

When Is Liability Insurance Mandatory?

Most self-employed people can take out liability insurance on a voluntary basis. However, there are certain professions and sectors where this insurance is required by law.

Mandatory Liability Insurance

The law requires professional liability insurance for the following regulated professions:

• Lawyers — mandatory under Act No. 85/1996 Coll., on the legal profession
• Tax advisors — under Act No. 523/1992 Coll., on tax advisory services
• Auditors — under Act No. 93/2009 Coll., on auditors
• Notaries — under Act No. 358/1992 Coll., on notaries
• Bailiffs — under Act No. 120/2001 Coll., on court bailiffs
• Authorised architects and engineers — under Act No. 360/1992 Coll.
• Insurance intermediaries — under Act No. 170/2018 Coll.
• Veterinary surgeons — under Act No. 381/1991 Coll.
• Doctors and healthcare providers — under Act No. 372/2011 Coll.
• Patent attorneys — under Act No. 417/2004 Coll.
• Expert witnesses — under Act No. 254/2019 Coll.

Voluntary but Highly Recommended Insurance

Even if your profession doesn't require mandatory insurance, there are sectors where liability insurance is effectively essential:

• Building and trade work — the risk of damaging a client's property is high
• IT services and software development — a single error can cause extensive financial harm
• Accounting and financial consulting — incorrect processing can lead to penalties
• Transport and courier services — liability for goods in transit
• Event organisers — liability for injuries to participants
• Personal trainers and instructors — risk of client injury
• Graphic designers and marketers — liability for copyright infringement

Types of Liability Insurance for the Self-Employed

Liability insurance is not a one-size-fits-all product. Several types exist, each covering different risks. Understanding the differences is key to choosing the right combination for your business.

1. General Third-Party Liability Insurance

This insurance covers damages caused to third parties in connection with your business activities. It's the most basic type of liability cover and is suitable for virtually every self-employed person.

What it typically covers:

• Damage to third-party property (damage or destruction)
• Personal injury to third parties (accidents at your premises or while working at a client's site)
• Consequential financial losses (a client's lost profit resulting from property damage)
• Legal representation costs

Example: A plumber floods a client's flat while repairing a pipe. General liability insurance covers the cost of repairing the damaged floor, repainting, and drying out the property.

2. Professional Indemnity Insurance (Errors & Omissions)

Professional indemnity insurance covers damages caused by an error or omission in the course of your professional work. It's essential for professions where the primary risk isn't physical damage but financial losses arising from incorrect advice or faulty work.

What it typically covers:

• Financial losses caused by professional negligence
• Costs of correcting or redoing defective work
• Legal defence costs against claims
• Penalties and fines a client must pay due to your error

Example: An accountant incorrectly prepares a client's tax return, resulting in the client receiving a penalty from the tax authority. Professional indemnity insurance covers the amount of that penalty.

3. Product Liability Insurance

If you manufacture or sell physical products, you need product liability insurance. It covers damages caused by a defective product to the health or property of a consumer.

What it typically covers:

• Personal injury caused by a defective product
• Property damage caused by a defective product
• Costs of recalling a defective product from the market
• Legal costs

Example: A maker of homemade candles — a defective candle causes a fire in a customer's flat. Product liability insurance covers the damage to the property.

4. Environmental Liability Insurance

A specialist type of insurance for businesses whose activities may cause environmental pollution. This applies to companies working with chemicals, waste management, or construction firms, among others.

5. Cyber Liability Insurance

A relatively new type of insurance that covers damages related to data breaches, cyberattacks, or GDPR violations. Increasingly relevant for self-employed people who handle sensitive client data.

What Liability Insurance Covers — and What It Doesn't

To avoid any unpleasant surprises when a claim arises, it's important to know exactly what your policy covers and what is excluded.

Standard Scope of Coverage

Insurance typically covers:

• Damage to third-party property
• Personal injury to third parties, including compensation for pain and suffering and loss of quality of life
• Consequential financial losses (lost profit resulting from property damage or personal injury)
• Legal representation costs and court proceedings
• Costs incurred to prevent an imminent loss
• Recourse claims from health insurance funds and the social security administration

Common Policy Exclusions

Insurance typically does NOT cover:

• Damages caused intentionally
• Damage to items you have rented or borrowed (unless separately insured)
• Contractual penalties and fines (unless explicitly included)
• Damages caused while under the influence of alcohol or drugs
• Damage resulting from normal wear and tear
• Damage to your own property
• War, terrorism, nuclear risks
• Damages arising from activities you are not licensed to perform

How Much Does Liability Insurance Cost for the Self-Employed?

The cost of liability insurance depends on many factors. Below is a rough overview to help you plan your budget.

Factors That Affect the Cost of Insurance

• Industry — higher-risk sectors (construction, healthcare) cost more
• Annual turnover — higher turnover typically means higher premiums
• Required coverage limit — the higher the maximum payout, the higher the premium
• Excess amount — a higher excess reduces the premium
• Claims history — previous claims increase the price
• Scope of coverage — additional riders and extensions increase the cost
• Number of employees — more workers means greater risk

Liability Insurance as a Tax-Deductible Expense

An important point for the self-employed: premiums for liability insurance covering damages arising from your business activities are a tax-deductible expense. You can therefore deduct them from your taxable income.

How to Choose the Right Liability Insurance

Choosing liability insurance shouldn't be rushed. The following steps will help you find the best option for your business.

What to Watch Out for When Choosing

Coverage limit: Don't go for the cheapest option with the lowest limit. The difference in premium between a 1 million Kč limit and a 5 million Kč limit is often just a few hundred crowns per year — but in the event of a claim, it can make a critical difference.

Excess: A higher excess lowers your premium, but it means smaller claims come out of your own pocket. Consider what excess level you can realistically afford.

Retroactive cover: For professional indemnity insurance, check whether the policy covers claims for incidents that occurred before the policy was taken out but are only reported after it starts (known as the claims-made basis).

Territorial scope: If you work abroad, check whether the policy provides cover outside the Czech Republic.

Liability Insurance vs. Other Insurance for the Self-Employed

Liability insurance is just one of the insurance products a self-employed person should consider. Here's an overview of how it differs from other types of business insurance.

What to Do When a Claim Occurs

If a damaging incident occurs, it's important to handle it correctly so you don't jeopardise your right to a payout.

Most Common Mistakes When It Comes to Liability Insurance

Based on common real-world experience, here are the most frequent mistakes self-employed people make with liability insurance:

1. Underinsurance — a coverage limit that's too low to reflect actual risks
2. Ignoring professional indemnity cover — taking out only general liability insurance, which doesn't cover professional errors
3. Not reading the policy terms — only discovering the exclusions when a claim arises
4. Failing to update the policy — cover no longer reflects the current scope of activities (expanded services, new area of work)
5. Late claims reporting — missing the deadline for notifying the insurer
6. Choosing on price alone — the cheapest policy often doesn't mean the best protection
7. Forgetting the tax deduction — not claiming insurance premiums as a tax-deductible expense

Frequently Asked Questions (FAQ)

Is liability insurance mandatory for the self-employed?

For most self-employed people, liability insurance is voluntary. It is only mandatory for legally regulated professions, such as lawyers, tax advisors, auditors, authorised architects, doctors, and others. For all other professions, however, it is highly recommended — particularly where there is a real risk of causing loss to clients.

How much does liability insurance cost for the self-employed?

Prices range from around 2,000 Kč per year for office-based professions with lower coverage limits to tens of thousands of crowns for high-risk sectors with high limits. The average self-employed person pays approximately 3,000–8,000 Kč per year for liability insurance.

Can I deduct the premium from my taxes?

Yes. Premiums for liability insurance covering damages caused in the course of business are a tax-deductible expense under the income tax act. This only applies, however, if you claim actual expenses — not if you use the flat-rate expense deduction.

What coverage limit should I choose?

The coverage limit should reflect the maximum realistic damage you could cause. A minimum of 2–5 million Kč is generally recommended. For construction, IT services, or consulting, a limit of 10 million Kč or more may be appropriate. A higher limit typically doesn't result in a significant increase in the premium.

What is an excess and how should I set it?

An excess is the amount you pay yourself for each claim. A higher excess reduces your premium, but means you cover smaller claims entirely out of your own pocket. A typical excess ranges from 1,000 to 10,000 Kč.

Does the insurance cover work done abroad?

It depends on the specific policy. Standard insurance usually applies within the Czech Republic, and in some cases the EU. If you work outside this area, you'll need to arrange an extension of the territorial scope. Always check this in your policy terms.

How quickly do I need to report a claim?

Most policies require notification without undue delay — generally within 3 to 5 working days from the moment you became aware of the damage. The exact deadline will be in your policy terms. Late reporting can result in a reduced or rejected payout.

Can I take out liability insurance with a different insurer than my other policies?

Yes, you can take out liability insurance with any insurer, regardless of where your other policies are held. However, it can sometimes be advantageous to consolidate multiple policies with one insurer to benefit from loyalty discounts.

Summary: Liability Insurance Is the Foundation of Responsible Self-Employment

Liability insurance is one of the most important risk management tools available to the self-employed. It protects your personal assets, enhances your credibility with clients, and gives you peace of mind as you go about your business.

Whether you're a tradesperson, IT consultant, accountant, or retailer — properly tailored liability insurance should be an integral part of your business. An investment of a few thousand crowns per year can protect you against losses running into hundreds of thousands or millions.
