What to check before choosing a broker in Czech Republic
Czech Republic offers one of the more favourable CGT regimes in Central Europe for long-term investors — a 15% flat rate, but with a critical 3-year time test that exempts gains entirely if you hold for over 36 months. Combined with a CZK 100,000 annual exemption threshold, patient investors can substantially reduce or eliminate their tax bill.
1. Regulation: ČNB and MiFID II. Česká národní banka (ČNB) — the Czech National Bank — serves as both the central bank and financial regulator. Czech Republic is a full EU member — MiFID II passporting applies in full. Verify at cnb.cz.
2. CGT: 15% flat — but 3-year time test applies. Czech capital gains tax (daň z příjmů fyzických osob z kapitálového majetku) is 15%. However, under the časový test (time test): shares held for more than 36 months are completely CGT-exempt. An additional annual exemption: if total securities gains in a year are under CZK 100,000, those gains are also tax-exempt regardless of holding period. Capital losses can be carried forward for 5 years.
3. Currency: Czech koruna (CZK). Czech Republic uses the CZK — it has not joined the Eurozone. XTB's Czech entity and local Czech brokers offer CZK-native accounts. EUR-based brokers (DEGIRO, IBKR) require CZK → EUR conversion at market FX rates.
4. Prague Stock Exchange (Burza cenných papírů Praha, BCP). The PSE PX Index covers Czech blue chips including ČEZ (CEZ), Komerční banka (KOMB), Erste Group (ERST), Moneta Money Bank (MONET), and O2 Czech Republic (TELEC). Access to the Prague exchange requires a broker with PSE connectivity — not all EU brokers cover it.
5. Dividend income. Dividends from Czech companies are subject to 15% withholding tax at source (srážková daň). Dividends from foreign companies are also taxable at 15% — foreign WHT may be credited under relevant double tax treaties (smlouvy o zamezení dvojímu zdanění). Declare foreign dividends in your daňové přiznání.

How to Get Started with a Broker in Czech Republic
1
Use the 3-year time test to eliminate CGT legally
Hold shares and ETFs for more than 36 months and your gains are completely exempt from the 15% Czech CGT. For long-term passive investors building a portfolio, this is highly valuable. Plan your purchase dates carefully — partial sales may trigger partial CGT if some lots fall below the 36-month threshold.
2
Keep gains below CZK 100,000 for annual exemption
If your total realized securities gains in a year are under CZK 100,000, they are tax-exempt regardless of holding period. This benefits smaller investors who realize modest gains annually. For gains above CZK 100,000 from holdings under 36 months, the full 15% rate applies.
3
Open account with Czech ID or EU documents
XTB's Czech entity (XTB Czech Republic, regulated by ČNB) offers CZK-native accounts with Czech document onboarding. DEGIRO, Interactive Brokers, and Trade Republic accept standard EU document KYC. Opening typically takes 1–3 business days.
4
Declare capital income in daňové přiznání (tax return)
Czech residents must declare capital income from foreign brokers manually in their annual daňové přiznání (tax return). XTB's Czech entity may provide year-end tax summaries for Czech residents. Keep annual statements from all brokers. Czech brokers also withhold 15% srážková daň on domestic dividends automatically.

EU / MiFID II
✅ Full EU member. MiFID II passporting applies — EU/EEA-regulated brokers can serve Czech residents. UK FCA-only brokers are NOT valid post-Brexit. Czech Republic is NOT in the Eurozone (uses CZK).
Investor Protection
€20,000 per investor under the Czech Guarantee Fund of Investment Intermediaries (Garanční fond obchodníků s cennými papíry). Bank deposits: up to €100,000 under Czech deposit insurance.
Capital Gains (Shares)
Flat 15% CGT on shares held under 36 months. 3-year time test Shares held >36 months: completely CGT-exempt. CZK 100k annual exemption Total annual gains under CZK 100,000: also tax-exempt. Losses carry forward for 5 years.
Dividend Tax
Czech company dividends: 15% withholding tax (srážková daň) withheld at source. Foreign dividends: taxable at 15%; foreign WHT credited under applicable double tax treaty. Declare foreign dividends in daňové přiznání.
ETF Tax Treatment
UCITS ETFs are subject to the same 15% CGT and 3-year time test as shares. For accumulating ETFs (which reinvest dividends internally), Czech law may treat notional distributions as taxable — consult a Czech daňový poradce (tax advisor) for fund-specific advice. Use UCITS not US-domiciled ETFs (PRIIPs applies).
US ETF Access (PRIIPs)
⚠️ Czech Republic is an EU member — PRIIPs applies. US-domiciled ETFs restricted for retail investors. Use UCITS-compliant equivalents. XTB, DEGIRO, and Trade Republic all offer broad UCITS ETF selections.

Frequently Asked Questions
How does Czech Republic's 3-year CGT time test work? +
In Czech Republic, capital gains from shares held for more than 36 months (3 years) are completely exempt from the 15% capital gains tax. You count from the date of purchase to the date of sale. If you sell before 36 months, the 15% rate applies on the full gain. If you sell after 36 months, the gain is tax-free regardless of size. This time test applies to shares and most securities but verify the treatment of specific investment fund types with a Czech daňový poradce (tax advisor).
What is the CZK 100,000 annual exemption in Czech Republic? +
Czech Republic provides an additional annual exemption: if your total capital gains from securities sales in a calendar year are below CZK 100,000 (roughly €4,000–5,000 depending on exchange rate), those gains are tax-exempt regardless of how long you held the investments. This is separate from the 3-year time test — you can benefit from either or both exemptions. Above CZK 100,000 in gains from holdings under 36 months, the 15% rate applies on the full amount.
Can EU brokers serve Czech investors? +
Yes. Czech Republic is a full EU member and MiFID II passporting applies. DEGIRO (AFM, Netherlands), Interactive Brokers (CSSF, Luxembourg), and Trade Republic (BaFin, Germany) can all legally serve Czech residents. XTB has a specific ČNB-regulated Czech entity offering CZK-native accounts. DEGIRO, IBKR, and Trade Republic are EUR-based and require CZK conversion. None of these EU brokers provide automatic Czech tax reporting — you must declare foreign broker income manually.
Is Czech Republic in the Eurozone? +
No. Czech Republic is an EU member but has not adopted the euro. It uses the Czech koruna (CZK). EUR-based brokers (DEGIRO, Interactive Brokers, Trade Republic) are EUR-denominated — Czech residents must convert CZK to EUR to fund these accounts and back again to CZK to spend gains, incurring FX costs both ways. XTB's Czech entity offers CZK-native accounts to avoid this friction.
