Sole Trader or Limited Company? The Big Comparison 2026
Choosing between operating as a sole trader and setting up a limited liability company (s.r.o.) is one of the most important decisions at the start of your business journey. Both structures have their advantages and disadvantages, and the right choice depends on a number of factors: income level, type of activity, degree of risk, need to work with partners, and personal preferences. In this article, we'll compare both options in detail, walk through specific tax burden calculations, and help you decide which is better for you.
Key Differences at a Glance

Liability: The Key Difference
Liability is often the main reason why business owners consider switching from a sole trader setup to a limited company.
Sole Traders Are Liable with All Their Assets
As a sole trader, you are personally liable for your business debts with all your personal assets — including your home, car, savings, and any other property you own. If your business runs into trouble and you're unable to repay your debts, creditors can go after everything you own. This risk can be partially mitigated with professional liability insurance, but it cannot be fully eliminated.
A Limited Company Separates Personal and Business Assets
With a limited company, as a shareholder you are only liable up to the amount of your unpaid share capital contribution. Once the contribution has been paid (which typically happens at the time of incorporation), you are not personally liable for the company's debts.
Watch out: a director's liability is broader
A director of a limited company has a duty to act with the care of a prudent manager. If they breach this duty and cause loss to the company as a result, they may be held personally liable. In the event of insolvency, a court may rule that the director is liable for the company's debts if they failed to file for insolvency in time or acted in breach of the law. So a director's liability is not zero.
Tax Burden: A Detailed Comparison
This is where the biggest differences — and the biggest confusion — arise. Let's break it down systematically.
How Taxation Works for Sole Traders
- Deduct expenses (flat-rate or actual) from income → taxable base
- Apply 15% tax to the taxable base (above CZK 1,762,812, the rate is 23%)
- Apply tax credits (personal allowance of CZK 30,840, etc.)
- Pay social insurance (29.2% on 50% of profit) and health insurance (13.5% on 50% of profit) on your profit (income minus expenses)
- Whatever's left is yours — you can use it freely
How Taxation Works for a Limited Company
- The company pays 21% corporate income tax on its profit
- If you want to withdraw money as a profit share, you pay an additional 15% withholding tax on the distributed amount
- The total tax on distributed profit is therefore: 100% − 21% = 79% → 15% is deducted from 79% → effectively 32.85% of the original profit
- If you pay yourself a director's salary, you pay standard employee and employer contributions
Ways to Withdraw Money from a Limited Company
Unlike a sole trader, where you simply transfer money from your account, a limited company requires you to choose one of the following methods:

Calculations: When Is a Sole Trader Better, and When Is a Limited Company?
We'll compare three scenarios. For the sole trader, we assume flat-rate expenses of 60% (general trade licence). For the limited company, we assume a combination of a minimum director's salary and profit share distribution.
Scenario 1: Profit of CZK 600,000
Profit CZK 600,000 – Sole Trader vs. Limited Company
Sole Trader (income CZK 1,500,000, flat-rate expenses 60%, profit CZK 600,000):
| Item | Amount | |---------|--------| | Income tax (15% of CZK 600,000 − personal allowance CZK 30,840) | CZK 59,160 | | Social insurance (29.2% of CZK 300,000) | CZK 87,600 | | Health insurance (13.5% of CZK 300,000) | CZK 40,500 | | Total contributions | CZK 187,260 | | Net income | CZK 412,740 |
Limited Company (profit CZK 600,000, full profit distributed as profit share):
| Item | Amount | |---------|--------| | Corporate income tax 21% | CZK 126,000 | | Net profit after corporate tax | CZK 474,000 | | Withholding tax 15% on profit share | CZK 71,100 | | Total contributions | CZK 197,100 | | Net income | CZK 402,900 |
Note: We haven't included a director's salary for the limited company — if the director also paid themselves a minimum wage, contributions would be higher, but they would accumulate pension insurance entitlement.
Result: At a profit of CZK 600,000, the sole trader structure is more advantageous by around CZK 10,000, and you also build up pension insurance coverage.
Scenario 2: Profit of CZK 1,200,000
Profit CZK 1,200,000 – Sole Trader vs. Limited Company
Sole Trader (income CZK 2,000,000, flat-rate expenses 60% = capped at CZK 1,200,000, profit CZK 800,000):
Note: With income of CZK 2,000,000 and 60% flat-rate expenses, the profit is CZK 800,000. But if actual costs are only CZK 800,000 and income is CZK 2,000,000, the profit equals CZK 1,200,000 using actual expenses. For this comparison, let's assume the sole trader has a profit/taxable base of CZK 1,200,000 (income CZK 3,000,000, flat-rate 60% = cap of CZK 1,200,000, profit CZK 1,800,000):
To keep things simple — the sole trader has a taxable base / profit of CZK 1,200,000:
| Item | Amount | |---------|--------| | Income tax (15% of CZK 1,200,000 − personal allowance CZK 30,840) | CZK 149,160 | | Social insurance (29.2% of CZK 600,000) | CZK 175,200 | | Health insurance (13.5% of CZK 600,000) | CZK 81,000 | | Total contributions | CZK 405,360 | | Net income | CZK 794,640 |
Limited Company (profit CZK 1,200,000, full profit distributed as profit share):
| Item | Amount | |---------|--------| | Corporate income tax 21% | CZK 252,000 | | Net profit after corporate tax | CZK 948,000 | | Withholding tax 15% on profit share | CZK 142,200 | | Total contributions | CZK 394,200 | | Net income | CZK 805,800 |
Result: At a profit of CZK 1,200,000, the limited company is slightly more advantageous by around CZK 11,000. But bear in mind — with a sole trader structure you build up pension insurance, while with a limited company and profit-share-only withdrawals, you don't.
Scenario 3: Profit of CZK 2,500,000
Profit CZK 2,500,000 – Sole Trader vs. Limited Company
Sole Trader (taxable base CZK 2,500,000):
| Item | Amount | |---------|--------| | Tax at 15% on CZK 1,762,812 | CZK 264,422 | | Tax at 23% on CZK 737,188 | CZK 169,553 | | Personal allowance | −CZK 30,840 | | Tax after allowance | CZK 403,135 | | Social insurance (29.2% of CZK 1,250,000) | CZK 365,000 | | Health insurance (13.5% of CZK 1,250,000) | CZK 168,750 | | Total contributions | CZK 936,885 | | Net income | CZK 1,563,115 |
Limited Company (profit CZK 2,500,000, distributed as profit share):
| Item | Amount | |---------|--------| | Corporate income tax 21% | CZK 525,000 | | Net profit after corporate tax | CZK 1,975,000 | | Withholding tax 15% on profit share | CZK 296,250 | | Total contributions | CZK 821,250 | | Net income | CZK 1,678,750 |
Result: At a profit of CZK 2,500,000, the limited company is clearly more advantageous — you save around CZK 115,000 per year.
General rule of thumb
The higher the profit, the more advantageous a limited company becomes. The tipping point is typically around an annual profit of CZK 800,000–1,200,000 (depending on your specific circumstances). Below this threshold, a sole trader structure is more beneficial; above it, a limited company tends to win out. That said, you need to factor in the higher costs of bookkeeping and administration that come with a limited company.
Administration and Running Costs
Sole Trader — Simplicity
- Setup: Register your trade at the trade licensing office (CRM – central registration point), fee of CZK 1,000. Done in 1–5 days.
- Bookkeeping: You only need to keep tax records (income and expenses). If using flat-rate expenses, you only need to track income.
- Annual obligations: Income tax return + reports for ČSSZ and your health insurer.
- Accountant costs: CZK 0 (you can handle it yourself) up to around CZK 5,000–15,000/year.
- Registry verification: Trade Licensing Register — verify your trade licence.
Limited Company — More Obligations
- Setup: Articles of association drafted by a notary (approx. CZK 5,000–10,000), entry in the Commercial Register (notary fee of CZK 2,700), plus any legal fees. Total: approx. CZK 10,000–25,000.
- Bookkeeping: Mandatory double-entry accounting. In practice, you'll need an accountant or accounting software.
- Annual obligations: Corporate income tax return, financial statements, publication of statements in the collection of documents (mandatory under the law and Commercial Register).
- Accountant costs: Approx. CZK 15,000–50,000/year (depending on transaction volume and complexity).
- Registry verification: Commercial Register — public register of companies.

Reputation and Business Relationships
In some industries, the legal structure you operate under does matter:
- A limited company comes across as more professional — for larger contracts, public tenders, and dealings with corporate clients
- A limited company makes collaboration easier — you can easily bring in a co-owner, sell a share, or transfer the business to someone else
- A limited company can obtain a business loan — kept separate from personal finances (though banks often still require a personal guarantee from the director)
- A sole trader structure is perfectly fine for many fields — freelancers, tradespeople, and consultants commonly operate as sole traders without any stigma attached
When to Switch from Sole Trader to Limited Company
📋Signs it may be time to consider switching to a limited company
How the Transition Works
Switching from a sole trader to a limited company isn't automatic — it involves setting up a new legal entity and gradually transferring your business activities:
- Incorporate a limited company (notarial deed, entry in the Commercial Register)
- Transfer contracts, clients, and obligations from yourself as an individual to the limited company
- Optionally contribute assets (car, equipment) to the company
- Your trade licence can be kept or suspended/cancelled
- Transition period — for a time, you can run both structures in parallel
Watch out for asset transfers
Contributing assets to a limited company can have tax implications. If you contribute assets (a car, property) as a non-cash contribution, an expert valuation is required. If you sell assets to the company, it counts as a commercial transaction with all the associated tax consequences. We strongly recommend consulting a tax adviser.
Other Legal and Practical Differences
Social and Health Insurance
As a sole trader, you always pay social and health insurance contributions — even if you have no income (for your primary activity). With a limited company, contributions are only paid on any salary that is paid out. If you only draw a profit share, you pay neither social nor health insurance on it.
However, this has consequences:
- Without a salary from the limited company, your pension insurance doesn't accumulate — you won't be building up working years toward your state pension
- Without paying health insurance contributions, you become a person without taxable income — you must pay health insurance as a "self-paying individual" (OBZP) (in 2026, a minimum of CZK 2,759/month), unless the state covers it for you
VAT
The obligation to register for VAT is the same for both sole traders and limited companies — turnover exceeding CZK 2,000,000 over 12 consecutive months. For more details, visit the Czech Financial Administration website.
Combining Both Structures
An interesting strategy is to run both a sole trader business and a limited company simultaneously. You could use the limited company for your main activity with higher turnover and greater risk, while keeping the sole trader structure for secondary income (such as consulting or speaking engagements). This combination can be tax-efficient, but requires careful planning.

Frequently Asked Questions (FAQ)
From what level of turnover does a limited company make sense?
There's no single definitive threshold, as it depends on many factors. As a rough guide: if your net profit (income minus actual expenses) consistently exceeds CZK 1,000,000 per year, and you also have reasons to separate your personal and business assets, a limited company is worth considering. At lower profit levels, the advantages of a sole trader structure (simplicity, flat-rate expenses, lower accounting costs) usually outweigh those of a limited company.
Can I have both a sole trader business and a limited company at the same time?
Yes, you can operate as a sole trader and simultaneously be a shareholder and/or director of a limited company. This is a common and perfectly legal arrangement. You do need to ensure that any transactions between you as a sole trader and your limited company take place at market rates (the arm's length principle).
How much does it cost to run a limited company's accounts?
It depends on the volume of transactions. For a small limited company processing a few dozen documents per month, expect to pay around CZK 2,000–5,000/month with an external accountant. For higher volumes, this can rise to CZK 5,000–10,000/month or more.
What happens if the limited company isn't making money?
A limited company can exist without generating income. However, you still need to meet your obligations — filing tax returns (even nil returns), maintaining accounting records, and publishing financial statements. Failure to comply can result in penalties.
Can I transfer my sole trader business to a limited company?
Not directly. A trade licence is tied to an individual. However, you can obtain a trade licence for the limited company (through a responsible representative, if required) and transfer your clients, contracts, and assets to it.
Is a single-member limited company legitimate?
Yes, a limited company can have one or more shareholders. A single-member limited company is a perfectly normal and widely used legal structure. The only restriction is that one individual cannot be the sole shareholder in more than three limited companies.
Do I pay social insurance as the director of a limited company?
If you pay yourself remuneration or a salary as director under an employment contract, social and health insurance contributions are due on it — both the employee and employer portions. If you only draw a profit share, you don't pay social insurance — but you also don't build up pension insurance entitlement.
