Freelancer and Taxes in the Czech Republic: 2026 Guide
Freelancing in the Czech Republic is growing year on year — IT developers, designers, copywriters, marketers, translators, and consultants are all enjoying the freedom of working for themselves. But with that freedom comes responsibility: filing tax returns, paying insurance contributions, issuing invoices correctly, and keeping track of legal deadlines. This guide will walk you through the entire tax life of a freelancer in 2026 — from day one of your business right through to submitting your return to the Czech Financial Administration.
Who is a 'freelancer' under Czech law?
Czech law doesn't recognise the term "freelancer." Legally, you are an OSVČ (self-employed person) holding a trade licence. A freelancer is essentially a sole trader who provides services under contracts with clients, rather than in an employment relationship. All the rules that apply to OSVČ therefore apply to you as well.
What type of trade licence does a freelancer need?
The type of trade licence you need depends on the nature of your work. Most freelancers fall into one of two categories:
Free trade licence (60% flat-rate expenses)
If your activity falls under one of the 80 fields covered by a free trade licence (Annex No. 4 of the Trade Licensing Act), all you need to do is register for 1,000 Kč (800 Kč online). Typical fields for freelancers include:
- Field No. 56 – Advisory and consultancy services, preparation of expert studies and assessments
- Field No. 59 – Graphic design and illustration work
- Field No. 60 – Translation and interpreting services
- Field No. 72 – Non-formal education and training, organising courses
- Field No. 78 – Advertising, marketing, and media representation
Regulated trade licence or activity under copyright law (40% flat-rate expenses)
Some professions don't fall under a trade licence at all, but under so-called "other self-employment" as defined in Section 7(2) of the Income Tax Act:
- Authors – writers, journalists, photographers (income from copyright)
- Court-appointed experts and interpreters
- Tax advisors, architects, solicitors – regulated professions
Why your type of trade licence matters for tax purposes
The type of trade licence you hold directly determines the level of flat-rate expenses you can deduct from your income:
- Free trade licence = flat-rate expenses of 60% of income (capped at 1,200,000 Kč)
- Other self-employment (authors, advisors) = flat-rate expenses of 40% of income (capped at 800,000 Kč)
- Craft trade licence = flat-rate expenses of 80% of income (capped at 1,600,000 Kč)
Most freelancers (IT, design, marketing, copywriting) hold a free trade licence → 60% flat rate.
Flat-rate expenses vs. actual expenses
This is a fundamental decision that will directly affect how much tax you owe.
Flat-rate expenses — ideal for freelancers with low costs
With flat-rate expenses, you deduct a fixed percentage of your income as set by law, with no need to document any actual expenditure. For most freelancers, this amounts to 60% of income.
Advantages:
- Simplicity — no need to collect and archive expense receipts
- Typically a higher deduction than actual expenses (freelancers rarely have significant operating costs)
- Lower risk of errors during a tax audit
Disadvantages:
- If you claim flat-rate expenses, you cannot claim the child tax credit (tax bonus)
- The maximum amount of flat-rate expenses is capped
Actual expenses — when you have high operating costs
If your real costs exceed the flat-rate percentage, it makes sense to keep detailed tax records and claim your actual expenses instead.
Typical freelancer expenses that can be claimed:
- Office or co-working space rental
- Computer, monitor, software, licences
- Internet and phone (pro-rated if also used privately)
- Professional courses and training
- Travel to clients
- Accounting and tax advisory fees
- Professional liability insurance
Example: Flat-rate vs. actual expenses (freelance designer)
| Item | Flat-rate expenses | Actual expenses | |------|--------------------|-----------------| | Annual income | 900,000 Kč | 900,000 Kč | | Expenses | 540,000 Kč (60%) | 180,000 Kč (actual) | | Tax base | 360,000 Kč | 720,000 Kč | | Tax at 15% | 54,000 Kč | 108,000 Kč | | Taxpayer credit | −30,840 Kč | −30,840 Kč | | Tax after credit | 23,160 Kč | 77,160 Kč |
In this example, the freelancer using flat-rate expenses saves 54,000 Kč per year in tax compared to claiming actual expenses. The flat rate almost always wins unless your real costs actually exceed 60% of your income.
Tax rates and calculating your tax in 2026
Income tax rate
The Czech Republic has a progressive tax system with two bands:
| Band | Annual tax base | Rate | |------|-----------------|------| | 1st band | Up to 1,676,052 Kč (36× average wage) | 15% | | 2nd band | Above 1,676,052 Kč | 23% |
The 15% rate applies to most freelancers. You only enter the higher band once your tax base (income minus expenses) exceeds approximately 1.68 million Kč, which corresponds to income of around 4.2 million Kč when using the 60% flat rate.
Taxpayer tax credit
Every taxpayer is entitled to a basic tax credit of 30,840 Kč per year (2,570 Kč per month). You claim this automatically in your tax return — no supporting documentation is required.
Full calculation of your tax liability
📋How to calculate a freelancer's income tax step by step
- Add up your annual income — all invoiced amounts received into your account (including cash payments if you accept them). What counts is the date the payment was received, not the date the invoice was issued.
- Deduct expenses — either flat-rate (60% of income for a free trade licence) or actual expenses. The result is your tax base under Section 7 of the Income Tax Act.
- Deduct non-taxable items — mortgage interest (up to 150,000 Kč), pension savings (up to 48,000 Kč), life insurance (up to 48,000 Kč), charitable donations (minimum 1,000 Kč, maximum 30% of the tax base).
- Round down to the nearest hundred — the tax base is rounded down to the nearest 100 Kč.
- Calculate the tax — tax base × 15% (or 23% on any amount above 1,676,052 Kč).
- Apply tax credits — taxpayer credit of 30,840 Kč, plus any credit for a spouse, disability, etc.
- Final tax liability = tax after credits. If the result is negative, your tax is zero (a tax bonus cannot be claimed when using flat-rate expenses).
Social and health insurance in 2026
Insurance contributions are often a bigger financial burden for freelancers than income tax itself.
Social insurance (pension insurance)
Social insurance contributions are administered by the Czech Social Security Administration (ČSSZ).
- Rate: 29.2% of the assessment base
- Assessment base: 50% of the difference between income and expenses (gradually increasing to 55% in 2026 under the consolidation package)
- Minimum monthly advance (primary activity): 5,720 Kč
- Minimum monthly advance (secondary activity): 1,574 Kč (where the obligation to pay arises)
Health insurance
Health insurance contributions are paid to your health insurance provider (e.g. VZP).
- Rate: 13.5% of the assessment base
- Assessment base: 50% of the difference between income and expenses
- Minimum monthly advance (primary activity): 3,306 Kč
- Secondary activity: no advance payments required (a lump-sum top-up is paid after submitting the annual statement)
Total minimum contributions for OSVČ in 2026
Minimum monthly contributions for a freelancer with primary activity (2026)
| Item | Monthly amount | Annual amount | |------|----------------|---------------| | Social insurance (min.) | 5,720 Kč | 68,640 Kč | | Health insurance (min.) | 3,306 Kč | 39,672 Kč | | Total minimum contributions | 9,026 Kč | 108,312 Kč |
These are the minimum advance payments. If your actual assessment base exceeds the minimum, you pay higher advances — these are recalculated after you submit your annual statement for the previous year.
Primary vs. secondary activity — a key distinction
If you freelance alongside employment, full-time study, maternity/parental leave, or while drawing a pension, your freelancing is classified as a secondary activity. In that case:
- You do not pay advance social insurance contributions if your annual profit does not exceed the threshold (for 2026, this is 117,553 Kč)
- You do not pay advance health insurance contributions — the insurance is settled as a lump sum
- Minimum contributions are significantly lower
Secondary activity is an ideal starting point for freelancers who want to test the waters before going fully independent.
Flat-rate tax — an alternative for freelancers
The flat-rate tax (paušální daň) is a simplified regime where you pay a single monthly amount that covers income tax, social insurance, and health insurance all at once. You don't need to file a tax return or annual insurance statements.
Eligibility requirements
- Annual business income up to 2,000,000 Kč
- Not registered as a VAT payer
- No employment income (except income taxed by withholding tax)
- Not a partner in a general partnership or a general partner in a limited partnership
Flat-rate tax bands for 2026
📊Flat-rate tax vs. standard regime for a freelancer
When the flat-rate tax makes sense for a freelancer
The flat-rate tax in Band 1 (9,984 Kč/month) is most beneficial for freelancers with annual income of roughly 400,000 Kč to 1,000,000 Kč, who don't have children (and therefore can't claim the child tax bonus) and want to keep admin to an absolute minimum. At lower income levels, the standard regime typically works out cheaper; at higher income levels, you'll need to compare against Bands 2 and 3.
Foreign clients and invoicing in foreign currencies
Many Czech freelancers work for clients abroad — whether EU-based companies or clients from the US and elsewhere. This raises some specific tax and administrative questions.
Invoicing in euros or dollars
As a Czech freelancer, you can issue invoices in any currency. For tax purposes, however, you must convert the income into Czech crowns. There are two ways to do this:
- CNB exchange rate on the date payment is received — this is the most common approach for OSVČ using cash-basis tax records, where income is recorded when payment is actually received
- Fixed rate — you set a fixed exchange rate at the start of the year based on the Czech National Bank rate and use it throughout the year. This makes your finances more predictable and reduces the effort involved in conversions.
Practical tip: Foreign currency account
If you regularly invoice in euros, consider opening a EUR foreign currency account. This avoids unnecessary conversion fees and lets you transfer funds into Czech crowns when the exchange rate is favourable. For tax purposes, what matters is the CNB rate on the day the payment arrives in your foreign currency account — not the date you convert it into crowns.
VAT on services provided to foreign clients
Even if you're not a VAT payer in the Czech Republic, when you provide services to businesses (B2B) in other EU member states, the reverse charge mechanism applies. This means:
- VAT is accounted for by the client in their own country
- You invoice without VAT
- Your invoice should include the note: "VAT to be accounted for by the customer (reverse charge) — Article 196 of Directive 2006/112/EC"
Important: If you provide services worth more than 2,000,000 Kč per year to businesses in the EU, you may be required to register as a so-called identified person for VAT purposes. Bear this in mind particularly if you work with large foreign clients.
Contracts with foreign clients — disguised employment
If you work long-term for a single foreign client (typically through platforms such as Toptal, Upwork, or directly), make sure your arrangement doesn't show signs of disguised employment (known in Czech as the "Švarc system"). Both the Czech authorities and your foreign client could face serious consequences. Signs to watch out for and avoid:
- Working exclusively for one client
- Fixed working hours set by the client
- Working solely from the client's premises
- Using only the client's tools and equipment
Double taxation treaties
The Czech Republic has double taxation treaties in place with most countries in the world. In practice, this means:
- Income from services you provide from your home in the Czech Republic to foreign clients is taxed only in the Czech Republic
- If a foreign client withholds tax on a payment (common with certain types of US income), you can offset that against your Czech tax liability (using the ordinary credit method) — you'll need to complete Appendix No. 3 of your tax return
Practical tax calculation examples
Example 1: Junior freelancer — designer with secondary activity
Example: Designer with secondary activity (income 250,000 Kč)
| Item | Amount | |------|--------| | Annual invoiced income | 250,000 Kč | | Flat-rate expenses 60% | −150,000 Kč | | Tax base | 100,000 Kč | | Tax at 15% | 15,000 Kč | | Taxpayer credit | −30,840 Kč | | Tax after credit | 0 Kč | | Social insurance (secondary) | 0 Kč (profit below threshold) | | Health insurance | 6,750 Kč (13.5% of 50,000 Kč) | | Total contributions | 6,750 Kč |
Effective tax rate: 2.7% of income
Example 2: Mid-level freelancer — software developer
Example: Developer with primary activity (income 1,200,000 Kč)
| Item | Amount | |------|--------| | Annual invoiced income | 1,200,000 Kč | | Flat-rate expenses 60% | −720,000 Kč | | Tax base | 480,000 Kč | | Non-taxable items (pension savings, mortgage) | −40,000 Kč | | Adjusted tax base | 440,000 Kč → rounded to 440,000 Kč | | Tax at 15% | 66,000 Kč | | Taxpayer credit | −30,840 Kč | | Tax after credit | 35,160 Kč | | Social insurance (29.2% of 240,000 Kč) | 70,080 Kč | | Health insurance (13.5% of 240,000 Kč) | 39,672 Kč (minimum) | | Total contributions (tax + insurance) | 144,912 Kč |
Effective tax rate: 12.1% of income
Example 3: High-earning freelancer — IT consultant
Example: IT consultant (income 2,400,000 Kč, actual expenses)
| Item | Amount | |------|--------| | Annual invoiced income | 2,400,000 Kč | | Actual expenses (office rent, hardware, software, travel) | −600,000 Kč | | Tax base | 1,800,000 Kč | | Non-taxable items | −50,000 Kč | | Adjusted tax base | 1,750,000 Kč | | Tax at 15% on 1,676,052 Kč | 251,408 Kč | | Tax at 23% on 73,948 Kč (above threshold) | 17,008 Kč | | Total tax | 268,416 Kč | | Taxpayer credit | −30,840 Kč | | Tax after credit | 237,576 Kč | | Social insurance (29.2% of 900,000 Kč) | 262,800 Kč | | Health insurance (13.5% of 900,000 Kč) | 121,500 Kč | | Total contributions | 621,876 Kč |
Effective tax rate: 25.9% of income. At this level, switching to a limited liability company (s.r.o.) is worth considering.
Key deadlines for freelancers in 2026
| Deadline | Obligation | |----------|------------| | By 12 January 2026 | Notification of entry into the flat-rate tax regime (for 2026) | | Monthly (by the 20th) | Social insurance advance payment | | Monthly (by the 8th) | Health insurance advance payment | | 1 April 2026 | Tax return for 2025 (paper submission) + tax payment | | 4 May 2026 | Tax return for 2025 (electronic submission) + tax payment | | 1 July 2026 | Tax return for 2025 (via tax advisor) + tax payment | | Within 1 month of filing the tax return | Annual statement for ČSSZ and health insurance provider | | Within 8 days of the top-up becoming due | Payment of any insurance shortfall |
Tax records for freelancers
As an OSVČ with income under Section 7, you are required to keep tax records (not full accounting, which only becomes mandatory once your turnover exceeds 25 million Kč or you are entered in the Commercial Register). Tax records consist of:
Required components
- Income and expense ledger — a chronological record of all income and expenses
- Receivables and payables register — an overview of unpaid invoices
- Asset register — if you have business assets (laptop, car, etc.)
What to archive and for how long
| Document | Retention period | |----------|-----------------| | Issued and received invoices | Minimum 5 years | | Bank statements | Minimum 5 years | | Tax returns | Minimum 5 years (10 years recommended) | | ČSSZ and health insurance statements | Minimum 10 years | | Client contracts | Duration of contract + 5 years |
Archiving obligations even when using flat-rate expenses
Even if you claim flat-rate expenses and don't need to document your costs, you are still required to archive your income records. This means all issued invoices and proof of payments received. The tax office can carry out an audit and ask you to substantiate the income you declared.
Frequently asked questions (FAQ)
Can I be both an employee and a freelancer at the same time?
Yes. In that case, your freelancing is classified as a secondary activity. Your employer handles the tax on your employment income, and you declare your freelancing income in your own tax return. Make sure to let your employer know that you'll be filing your own return (you either don't sign the tax declaration with your employer, or you do — but in that case, you must still file a tax return if your business income exceeds 20,000 Kč).
Do I have to pay VAT as a freelancer?
Not unless your turnover exceeds 2,000,000 Kč in a calendar year (or 2,536,500 Kč in any 12-month period). You can, however, register for VAT voluntarily, which can make sense if most of your clients are VAT-registered themselves (they can reclaim the VAT) and you incur significant VAT-inclusive expenses (rent, equipment, etc.).
How do I declare income from platforms like Fiverr or Upwork?
Income from online platforms is treated as ordinary self-employment income. If you invoice through the platform, you record the income when the money arrives in your account (or becomes available for withdrawal from your platform account). Platform fees (Upwork service fees, Fiverr commission) count as an expense and can be deducted if you're claiming actual expenses.
What if I'm a freelancer and also have rental income?
Each type of income is taxed separately — freelancing under Section 7, rental income under Section 9. The flat rate for rental expenses is 30%. All income streams are combined in a single tax return. Bear in mind that combining business and rental income can complicate entry into the flat-rate tax regime.
Can I deduct home office expenses as a freelancer?
Yes, but only when claiming actual expenses. You can deduct a proportionate share of your housing costs (rent, utilities, internet) corresponding to your work use. This is typically calculated based on the ratio of your workspace area to the total floor area of your home. If you're using flat-rate expenses, home office costs are already factored in.
When does it make sense to switch from OSVČ to a limited liability company (s.r.o.)?
A common rule of thumb: once your annual income consistently exceeds around 1.5–2 million Kč, it's worth considering switching to an s.r.o. A limited company pays 21% corporate income tax, and dividends are subject to an additional 15% withholding tax — giving a combined effective rate of around 32.85%. However, you don't pay social and health insurance on the company's entire profit — only on the salary paid to you as director/employee. At high income levels, this can result in significant savings on contributions.
