TTPA compliance deadline

The TTPA compliance deadline refers to the date by which all parties subject to Regulation 2024/900 must fully comply with its transparency and targeting requirements for political advertising. The regulation applies from 8 October 2025 for transparency obligations (Chapter II) and from 8 April 2025 for targeting restrictions (Chapter III). This creates two separate compliance deadlines depending on which obligations apply to your activities.

Legal Basis

"This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. Articles 4 to 17 [transparency and due diligence obligations] shall apply from 8 October 2025. Articles 18 to 23 [targeting and amplification techniques] shall apply from 8 April 2025."

— Article 30, Regulation 2024/900

Why It Matters

The staggered compliance deadlines mean that sponsors, publishers, and providers of political advertising services must prepare for two different implementation dates. Targeting restrictions—which ban the use of certain personal data categories and require specific legal bases for online political ad targeting—must be in place six months before the transparency requirements.

This timeline reflects the complexity of implementing targeting controls, which often require technical changes to advertising systems, data processing agreements, and consent mechanisms. Organizations using personal data to target or amplify political advertising online need to audit and potentially redesign their systems before April 2025.

For transparency obligations—including labelling political ads, providing transparency notices, maintaining records, and establishing reporting channels—the October 2025 deadline allows more time for operational preparation. However, publishers and sponsors should not wait until the last moment, especially if they plan to run political campaigns during the 2024–2025 electoral period across EU Member States.

Key Points

Two deadlines: 8 April 2025 for targeting restrictions (Chapter III), 8 October 2025 for transparency obligations (Chapter II)
Targeting comes first: Organizations must stop prohibited data processing and implement lawful targeting mechanisms six months before transparency requirements take effect
Applies EU-wide: All political advertising directed to individuals in EU Member States must comply, regardless of where the sponsor or publisher is established
No grace period: The regulation provides no transition period or exemptions for elections occurring immediately after the deadlines
Preparation needed: Technical implementation, staff training, policy updates, and vendor compliance reviews should begin well before the deadlines
Enforcement from day one: National competent authorities and data protection authorities can investigate and sanction non-compliance once the respective deadlines pass

TTPA compliance deadline vs. GDPR compliance deadline

The TTPA compliance deadlines function similarly to the GDPR's enforcement date (25 May 2018), but the TTPA introduces two staggered deadlines rather than one. Like the GDPR, Regulation 2024/900 was published in the Official Journal and enters into force 20 days later, but most substantive obligations only apply months afterward.

Aspect	TTPA deadlines	GDPR deadline
Number of deadlines	Two (April and October 2025)	One (May 2018)
Grace period	None	Two-year transition
Scope	Political advertising only	All personal data processing
Sanctions	From compliance date	From compliance date

Unlike the GDPR, which allowed a two-year transition period between adoption and application, the TTPA's timeline is shorter—approximately 18 months from publication to the first deadline. Organizations already subject to GDPR will need to layer TTPA-specific requirements on top of existing data protection obligations.

Very transparent. Every political ad will be labelled, linked to a transparency notice with detailed information, and online ads will be searchable in a central European repository.

The Network coordinates election-related cooperation between member states. National contact points for TTPA enforcement should be members of this network where possible.

Election campaigns will need to ensure all paid advertising includes proper labels and transparency notices. Sponsors must be prepared to provide required information to all service providers.

Several major platforms currently do not allow paid political advertising, including some large social networks. This limits where political actors can place paid online advertisements.

The TTPA applies from 10 October 2025. Member States had until 10 April 2025 to designate competent authorities, and the Commission must provide label templates by 10 July 2025.

Publishers must ensure completeness and accuracy of certain information but are not required to verify all sponsor claims. They must correct manifestly erroneous information when they become aware of it.

Yes. When a hosting provider and a website both display an ad, both are considered publishers with responsibility for their specific services. Contracts should clarify how they share compliance duties.

If a publisher removes or disables access to a political ad due to illegality or terms violations, they must still provide access to the transparency information for the full seven-year retention period.
