Airbnb in Prague: what is legal, what is not and what is still moving

A tourist who books a flat in Žižkov for a long weekend gives little thought to who is on the other side of the booking. The host may be a family renting out a second flat, a company managing thirty flats, or a tenant who never told the landlord. Their obligations are not identical, and the gap between "everyone does it" and "everyone does it legally" is where most trouble starts.

This article sets out what the rules ask of a host in Prague, what the 2026 EU regime changes, and where the legal picture is still unsettled. It does not take a view on whether short-term letting is good for the city, which is a live political argument. For the rules that fall on owners inside an apartment building, see our companion piece on short-term rental rules for Prague apartment owners.

Is it legal at all?

In principle, yes. Czech law does not ban an owner from letting their flat for short stays, and a platform listing is not unlawful in itself. What the law does is attach duties to the activity. Some come from national law and some from the building or contract. The EU has added a layer from 20 May 2026.

The things that make a short let unlawful or risky are usually these:

• the host is a tenant who did not get the landlord's consent to sublet; under the Civil Code a tenant may not give the flat to a subtenant without it (§ 2274);
• the building's declaration or house rules restrict use, or the owners' association has rules that the let breaks;
• the host does not report foreign guests or collect and pass on the municipal fee;
• the income is not declared;
• the lender's contract forbids letting.

None of these is a ban on Airbnb. Each is a way of getting the lawful version wrong.

The duties of a host

Reporting guests. Anyone who provides accommodation for payment is an accommodation provider (ubytovatel) and must report each foreign guest to the police within 3 working days of arrival. That includes EU citizens, so a German couple counts as much as an American one. The police run an online system, Ubyport, for the purpose, and the guest book is kept for six years (as of 2026; check the Police of the Czech Republic). Hosts who skip it are the ones a foreign police check finds. See our guide to registering an address with the foreign police for how the process looks from the guest's side.

The accommodation fee. Municipalities set a local fee on stays (poplatek z pobytu) by decree. The Act on Local Fees caps it at CZK 50 per person per day, and Prague has charged that maximum since 2022 under its decree no. 18/2019, for paid stays of up to 60 consecutive days. The day of arrival is not counted, and some groups are exempt. The host collects the fee from guests, keeps a record of who stayed and pays it to the city. The exemptions, the reporting deadlines and the rate are set in Prague's decree, so check Prague City Hall before the first guest arrives (as of 2026). Proposals to raise the legal ceiling have been made but had not been enacted by October 2026.

Income tax. Rent from a flat is income. For a private landlord, rental income is taxed with a choice of actual expenses or a 30% flat-rate deduction capped at CZK 600,000, and no social or health insurance is due on private rental income of this kind. Whether short stays count as passive rental or as a business depends on scale and on services such as cleaning, breakfast or concierge duties, and a tax adviser or the Financial Administration should answer that for your case (as of 2026). Our guide to tax on rental income explains the basic method.

VAT. A host turning over more than CZK 2,000,000 in a calendar year becomes a VAT payer from 1 January of the next year (as of 2026; check the Financial Administration). Few single-flat hosts get near it, but a host with several flats can.

What the EU changed in 2026

Regulation (EU) 2024/1028 on data collection and sharing relating to short-term accommodation rental services applies from 20 May 2026. In outline, it sets up a common framework: member states may require hosts to register and receive a registration number, platforms must display the number and check that hosts are registered, and platforms must pass activity data to national authorities on a regular basis.

The word to note is "may". The Regulation harmonises the data flows and gives states the tools. The Czech answer is an amendment to the Act on Business in Tourism (zákon č. 159/1999 Sb.) that would create eTurista, a national register of accommodation with registration numbers for hosts and electronic guest reporting. A previous version stalled in the Chamber of Deputies before the 2025 election, and the new government's version was still going through the legislative process when this was written in October 2026. Press reports say it would also let municipalities cap the number of days a flat may be let or set periods when short lets are barred. None of that is law yet, so check the Ministry for Regional Development for the current position, and do not assume that "no registration yet" means "no registration soon".

Subletting and owners' associations

Two other parties can say no. A landlord can refuse to allow a holiday let by a tenant, and a tenant who lets without consent risks losing the lease. The owners' association is the other. In 2023 the Supreme Court held that an association cannot ban short lets through its statutes, but owners must not disturb the others beyond what is reasonable, and a pattern of noise and key-box traffic can end in court. Lower courts have since reached different results on particular buildings, so this is not settled ground. Our article on building owners' meetings and voting explains how those rules are made, and the companion piece covers them for owners.

A mortgage is a third party. Lenders usually require that the property is used as described in the loan agreement, and some restrict letting without consent. Read the contract before you list.

Three kinds of host, three sets of exposure

The rules fall differently on three kinds of host, and the same flat can sit in any of them depending on who runs it.

An owner letting a spare flat is the simplest case. The owner decides, bears the tax and answers to the building and the lender. A tenant who sublets has the shakiest footing, because the right to let belongs to the landlord, and a platform listing without written consent is a breach waiting to be found. An operator managing several flats for other owners, or holding several leases, looks like a business and is likely to be treated as one: a trade licence, bookkeeping and a closer eye on the VAT threshold. Our guide to how to become self-employed covers the registrations that follow.

Mistakes that bring the trouble

Hosts rarely get into difficulty for a single large reason. It is usually a handful of small omissions that add up.

• Assuming the platform collects and passes on the local fee. Whether it does in your case is something to confirm with the platform and the municipality, not to assume.
• Keeping no guest log. The fee and the foreign-guest report both depend on knowing who stayed and when.
• Treating the platform's payout as net income. The payout is after the platform's commission; the income for tax purposes and the costs are another calculation.
• Posting entry codes in the listing, which is the quickest route to a complaint from the building.
• Never reading the lease, the loan agreement or the insurance policy for the clause that matters.

None of these is dramatic. All of them are avoidable by an afternoon with the documents.

The numbers behind the decision

Does it pay? That depends on occupancy, costs and your time, which we work through on hypothetical figures in short-term or long-term letting in Prague: comparing returns. For a yield check on a specific flat, the rental yield calculator on Hypoteky.com lets you test your own rent, costs and price.

Frequently asked questions

Do I need a trade licence to let my flat on Airbnb?

It depends on scale and services. Occasional letting of your own flat may be passive rental income; regular letting with services may be a business. Ask a tax adviser or the Financial Administration.

Can a tenant list the flat they rent?

Only with the landlord's consent. Without it the tenant breaches the lease and risks losing the flat (Civil Code, § 2274).

Is there a limit on the number of nights?

No. There was no national or Prague cap on nights as of October 2026. The eTurista bill would let municipalities set one, so check the Ministry for Regional Development and Prague City Hall.

Do I have to pay the accommodation fee myself?

The host collects the fee from guests and pays it to the municipality. Prague sets the rate and the exemptions by decree, within the legal ceiling of CZK 50 per person per day (as of 2026).

A practical next step

Ask the municipality where the flat is how the accommodation fee works there, and ask the Ministry for Regional Development whether a registration number is now required. Those two answers change what you do in the first week.
