If you have been reading those articles and frantically searching for a way to register in a system that does not yet exist, this article is for you.
The reality is far calmer than the headlines. Here is what actually happens on 20 May 2026 and when you genuinely need to take action.
Why is the internet scaring hosts about 20 May?
20 May 2026 is technically the date from which EU Regulation 2024/1028 on short-term rental data starts to apply in all 27 EU member states. Most articles stopped there and drew a simple but incorrect conclusion: "since the regulation enters into force, hosts must have a registration number from 20 May". The problem is that an EU regulation is only the framework. For it to work in Poland, several other things need to be in place, and on 20 May none of them are.
What technically happens on 20 May 2026?
Regulation 2024/1028 is a directly applicable act, meaning it formally applies from 20 May without needing transposition into national law. However, its core provisions on registration and platform verification of numbers presuppose that:
- a functioning national registration system exists with a public API accessible to platforms,
- property owners have a way to apply for and receive a registration number,
- national enforcement authorities have the tools to act.
In Poland, as of 7 May 2026, none of these conditions are met.
Why the rules have no practical effect in Poland
The UC135 act has not been passed
Poland's implementing legislation, known in the legislative process as UC135, held its first reading in parliament on 14-17 April 2026, barely one month before the EU deadline. After the first reading it was referred to parliamentary committees, where substantive work continues.
Before the act comes into force it must pass a second and third reading in the Sejm, a vote, the Senate, the President's signature and publication in the Journal of Laws. After that, a vacatio legis period begins for owners, municipalities and platforms to adapt. The earliest realistic estimate: autumn 2026.
The CWTON system does not exist
CWTON is not just a legal provision: it is an IT system, a database, a registration portal, a platform API and administrative dashboards for local officials. As of 20 May 2026, none of this infrastructure exists. The Ministry of Sport and Tourism has stated that the system will be launched after the act is passed and after municipalities have built their local databases.
Furthermore, Deputy Minister Ireneusz Raś confirmed on 15 April 2026 that at the request of local governments the deadline for municipalities to set up their databases and start issuing registration numbers has been pushed to 15 October 2026.
Booking.com and Airbnb will not enforce the requirement
Platforms which under EU Regulation 2024/1028 are required to verify registration numbers also cannot act without a register to verify against. Booking.com officially confirmed it cannot enforce the registration number requirement in Poland because no national implementing legislation exists and no CWTON system is operational.
This means that on 20 May 2026 your Airbnb and Booking.com listings will not be removed, hidden or flagged as non-compliant. The platforms simply have no database to check your listings against.
When do the rules actually take effect? 15 October 2026
Based on available information, the real practical deadline by which Polish hosts will need a CWTON number is around 15 October 2026. This date, confirmed by Deputy Minister Raś, is when municipalities are required to have their local databases ready and start processing registration applications.
A realistic sequence of events:
- June-July 2026: Second and third readings of UC135 in the Sejm, Senate, Presidential signature
- August 2026: Act published in the Journal of Laws; vacatio legis begins
- 15 October 2026: Municipalities launch local databases and start accepting CWTON applications
- October-November 2026: Hosts receive CWTON numbers and update listings; platforms begin verification
It is worth following communications from the Ministry of Sport and Tourism, as dates may shift further during the legislative process.
What should you do right now?
Nothing urgent, but that does not mean nothing at all. This is a good time to prepare calmly before the autumn rush for registration numbers.
- Check your legal title to the property. Registration will require proof of right to use the property (ownership deed, or a sublease agreement that permits subletting, or a power of attorney from the owner).
- Sort out your fire safety documentation. CWTON registration will require a declaration of compliance with fire safety requirements. Better to address this now. See our article Fire safety requirements for short-term rentals.
- Set up a Trusted Profile. Registration will go through gov.pl authenticated with a Trusted Profile (Profil Zaufany) or e-ID. If you do not have one yet, you can set it up through online banking in about five minutes.
- Review your compliance documentation. CWTON is one element of a broader package of host obligations. Check the full document checklist for hosts so nothing catches you off guard in autumn.

Frequently asked questions
Should I register in CWTON before 20 May?
You cannot, because the CWTON registration system does not exist. There is no platform where you could submit an application. When the system is launched, most likely in October 2026, we will publish a detailed step-by-step registration guide.
Will Airbnb remove my listing on 20 May?
No. Airbnb and Booking.com have confirmed they cannot enforce the registration number requirement because there is no CWTON system against which they can verify data. Your listings remain active.
Can I be fined for not having a CWTON number after 20 May?
No. Fines can only be imposed after the Polish UC135 act is passed and its penalty provisions enter into force with the applicable vacatio legis. Until then, no Polish authority has the legal basis to penalise hosts for lacking a registration number that cannot yet be issued.
How will I know when the rules really come into force?
