Online Casinos in Czechia

License for online casinos from the Czech Republic

The modern Czech regime is built on Act No. 186/2016 on gambling, enforced by the Ministry of Finance. Online casino types allowed by law include lotteries, odds betting, totalizators, bingo, technical games such as slots, and live games, provided their design supports remote play. As of 2024, the law explicitly covers live dealer studio games and broadens what counts as an online game offered into the country if it is accessible on Czech territory. Oversight sits with the Ministry’s Department 73, which drafts rules, supervises operators, runs the excluded persons register, and orders site and payment blocking for illegal games. The Customs Administration performs control procedures and administrative offense proceedings in the field.

Only corporations based in the Czech Republic, another EU state or EEA country may operate, and they must show a clear governance structure, transparent ownership and source of funds, sufficient capital (at least EUR 2,000,000), and adequate technical and staffing capacity. Operators need a Ministry license and must lodge a financial guarantee that covers taxes, administrative fines, and unpaid winnings if necessary. The law sets minimum guarantees by product: CZK 30,000,000 for odds betting, totalizators and bingo, and CZK 50,000,000 for lotteries, technical games and live games (their online versions included). These guarantees are held on a special Ministry account or via a bank guarantee and act as a backstop if an operator fails.

The Czech standard aims to protect player funds and game integrity through strict account separation and certified systems. Each player may hold only one account with an operator. Registration requires identity and age verification (18+), with a remote method available; if that is not possible, in‑person verification is required. Before activation, operators must check the national Register of Excluded Persons and allow the player to set personal limits or decline to set them. Temporary accounts can run only up to 30 days and accept at most CZK 3,000 in total deposits; withdrawals are blocked until full verification, and any unclaimed funds must be returned if registration fails.

The law forces online casinos to publish, in Czech and prominently on the gaming webpage, the operator’s identity and contacts, the licensing authority and license number, the full game plan, responsible‑gambling and harm warnings, 18+ notices, and the contact of help services. During play, the site must display elapsed session time, harm warnings, account balance, and applicable maxima such as stake or win caps.

Responsible gambling is codified. Players can set daily and monthly caps on stakes and net losses, limit log‑ins per month, set a maximum daily session length before auto‑logout, and enforce a cooling‑off period after logging out. Tightening limits takes effect immediately (no later than within 24 hours); any relaxation becomes effective only after seven days. Operators must block participation if a player hits their own limits. A national Register of Excluded Persons bars listed individuals from all licensed gambling that requires registration or identity checks, including all online games. Since 1 July 2024, every operator must provide a 48‑hour “panic button” in the user account that instantly blocks the player from gambling at all operators nationwide; for long‑term protection, a player can request being added to the exclusion register, including directly via their casino account.

Security and fairness are backed by certified technology. RNG‑based games must use assessed systems, servers for certain online games must be located in the EU/EEA, and operators must keep detailed logs of bets, payouts, odds and changes for up to ten years depending on the record type. The Ministry maintains a blacklist of unauthorized online games: Czech ISPs must block listed sites within 15 days of publication, and payment providers must stop transactions to blacklisted accounts within the same timeframe. Administrative sanctions for breaches scale into tens of millions of crowns and may include suspensions of up to two years and confiscations.

Payment rules are narrow by design. Deposits and withdrawals must run through a “registered payment account” or card owned by the player and provided by an EU/EEA‑authorized payment service. Cash transactions linked to online gambling are permitted only up to CZK 5,000 per 24 hours and must be recorded and archived. Transfers between player accounts are banned. The law does not recognize cryptocurrencies as a registered payment method; if a site oriented to Czech players promotes crypto deposits, it is unlikely to operate under a Czech license.

Limits and taxes

For online technical games such as slots, the minimum payout percentage is 75 percent. A single spin may not exceed a stake of CZK 1,000, the maximum win per spin is CZK 500,000, a spin must last at least two seconds, and continuous play must be interrupted every 120 minutes by a mandatory 15‑minute break. Temporary accounts are capped at CZK 3,000 total deposits and expire after 30 days without full verification; until then, withdrawals are disabled.

Taxation has been reshaped since 1 January 2024. According to the updated regime, the game tax rate stands at 35 percent of GGR for lotteries and technical games, while live games, bingo, odds betting (including live betting), totalizators, raffles and small poker tournaments are taxed at 30 percent of GGR. The personal tax threshold for player winnings has been reduced to CZK 50,000; whether the tax is withheld or included in the player’s tax base depends on the type of win and the applicable mechanism.

How to check whether a casino holds a Czech license

The first check is on the casino’s own website. A Czech‑licensed operator must state, in Czech and visibly, its legal name, contact details, the authority that granted the license and the license number, the game plan, 18+ restrictions, warnings and help contacts. If this block is missing, the site is unlikely to be licensed in the Czech Republic.

The second check is in the official whitelist. The Ministry of Finance publishes the current “Seznam legálních provozovatelů hazardních her” (list of legal operators). Open the 2025 overview and download the latest file dated to the day; then search by the operator’s corporate name. The list is maintained by Department 73 and updated throughout the year. Official page: official whitelist overview. Once you find a match, treat the corporate name on the whitelist as the legal backbone behind any consumer‑facing casino brand.

How to file a complaint against a Czech‑licensed online casino

Start with the casino’s customer support under the procedure in its published game plan. The law gives the operator a defined window to investigate and respond; if it refuses your claim or simply fails to answer in time, enforcement moves to the state authorities.

For unpaid winnings in online gambling, the Ministry explains a clear route. You may lodge a complaint with the Customs Administration, which conducts control proceedings in gambling cases. The General Directorate of Customs is seated at Budějovická 7, 140 96 Praha 4. If the local customs authority confirms an administrative offense and the damage meets the legal conditions, it can order payment of the proven part of your claim in the same proceeding. If the operator pays voluntarily during the case, the matter ends; otherwise, unresolved parts can be pursued in civil court. Separately, if an operator ultimately exits the market or loses its permit, you may register a proven unpaid win for payment from the operator’s financial guarantee held by the Ministry, following the Ministry’s published window and forms. Guidance and forms are available here: unpaid winnings: how to proceed and the Ministry’s detailed PDF information note.

Customs investigates and may order restitution in an administrative offense case if statutory conditions are met; otherwise, the dispute continues in civil court. The Ministry can then use the operator’s financial guarantee to satisfy registered, proven claims within the legal framework and time windows it announces. For responsible‑gambling issues, you can activate the nationwide 48‑hour panic button in your account, or request long‑term exclusion via your account or the public portal at RVO online forms. For general questions, the Ministry publishes contacts including loterie@mfcr.cz and its central registry office; however, enforcement in disputes runs through the procedures above.
