October 2026: The Publisher Compliance Deadline

Two Dates, One Regulation

Regulation (EU) 2024/900 operates on a staggered timeline. Understanding which deadline applies to you is critical:

• October 2025: The regulation entered into force. From this date, the core obligations apply — including the requirement for advertisers to create transparency notices for political advertisements.
• October 2026: The deadline for publishers to fully implement their verification systems under Art. 11 PAR. After this date, publishing a political ad without verifying the associated transparency notice can result in penalties.

This distinction matters. The regulation is not something that "starts in October 2026." It is already in effect. What October 2026 adds is the full enforcement of the publisher verification duty.

What Is Already Required (Since October 2025)

Since the regulation entered into force, the following obligations are active:

For advertisers

• Every political advertisement must be accompanied by a complete transparency notice as defined in Art. 9 PAR
• The notice must be created before the ad is published
• The notice must be publicly accessible and maintained for five years (Art. 12)
• A complaint mechanism must be in place (Art. 15)

These obligations are not future requirements. They apply now. Advertisers who place political ads today without transparency notices are already in potential violation of the regulation.

For online platforms

Very large online platforms (VLOPs) already have related obligations under the Digital Services Act (DSA) regarding political advertising transparency. The PAR extends and specifies these duties further.

What Changes in October 2026

The October 2026 deadline specifically concerns the publisher verification duty established in Art. 11 PAR:

The verification obligation

From October 2026, every publisher must verify — before publishing a political advertisement — that:

1. A valid transparency notice exists for the ad
2. The notice contains the required information as specified by Art. 9 PAR and Implementing Regulation (EU) 2025/1410
3. The notice is publicly accessible

This is an active duty, not a passive one. The publisher must have a process in place that systematically checks for and validates transparency notices. A publisher that simply publishes whatever advertisers submit, without any verification, is in violation.

Why the delay?

The EU recognized that publisher verification requires operational changes. Newspapers, broadcasters, and advertising platforms need to:

• Design and implement new workflows
• Train staff
• Integrate verification into their existing ad acceptance processes
• Potentially adopt new technical systems

The 12-month transitional period (October 2025 to October 2026) was granted specifically to allow publishers time to build these processes. It is not an exemption — it is a preparation period.

Who Counts as a Publisher

The scope of Art. 11 is broad. "Publisher" includes anyone who distributes a political ad to the public:

• Newspapers and magazines — both print and digital editions
• Broadcasters — television and radio stations
• Outdoor advertising companies — billboard operators, transit advertising firms, digital signage networks
• Online news portals — websites that combine editorial content with advertising
• Advertising agencies and media buyers — insofar as they arrange for the placement of ads
• Community newspapers and local media — no size threshold; even small publications are covered
• Event organizers — if they sell advertising space at events (e.g., banners at political rallies)

If your organization distributes advertising to the public and any of that advertising could be political in nature, the October 2026 deadline applies to you.

What Publishers Should Do Now

The deadline is October 2026, but preparation should start immediately. Here is a practical roadmap:

1. Assess your exposure

Determine how often your organization publishes ads that could be political. If you are a newspaper, the answer is likely "frequently." If you are an outdoor advertising company, it may be seasonal (around elections). Understanding your exposure helps you size the effort.

2. Define your verification process

Decide how your organization will verify transparency notices. Key questions:

• Who in your organization is responsible for checking?
• When in the ad acceptance workflow does verification happen?
• What do they check — is the notice complete, accurate, publicly accessible?
• How do they document the verification?

3. Register on The Taurus

The Taurus provides a structured way for publishers to verify transparency notices. When an advertiser creates a notice through The Taurus, it generates a unique public ID that publishers can use to verify the notice exists and is complete. This eliminates the need for manual verification of individual data fields.

4. Onboard your advertisers

Reach out to organizations that regularly place political advertising with you. Inform them about the regulation and encourage them to start creating transparency notices now. The earlier your advertisers adopt the process, the smoother your own verification workflow will be.

5. Train your team

Ad sales staff, editorial assistants, and anyone involved in the ad acceptance process needs to understand:

• What a political ad is (the definition is broader than most people expect)
• What a transparency notice is and why it is required
• How to verify that a valid notice exists
• What to do if a notice is missing or incomplete (refuse the ad, request correction)

6. Test and refine

Run your verification process on a trial basis before October 2026. Use existing political ads to practice. Identify bottlenecks and refine the workflow.

The Consequences of Missing the Deadline

After October 2026, a publisher that publishes a political advertisement without verifying the transparency notice is in violation of Art. 11 PAR. The consequences can include:

• Financial penalties up to 6% of annual turnover (Art. 29 PAR)
• Orders to cease publication of the non-compliant advertising
• Public enforcement decisions that create reputational damage

The publisher's liability is independent of the advertiser's compliance. Even if the advertiser has failed to create a notice, the publisher is responsible for catching that failure before publication. The verification duty means that "we did not know" is not a viable defense.

Advertisers: Why This Matters to You

Even though the October 2026 deadline is about publisher verification, it has direct consequences for advertisers:

Starting in October 2026, publishers will refuse to run your political ads if you cannot demonstrate that a valid transparency notice exists. This is not optional for them — it is a legal requirement.

If you wait until October 2026 to start creating transparency notices, you may find that newspapers and platforms reject your ads at the worst possible time — during a campaign. The best approach is to start now, establish the habit, and have your processes in place well before publishers begin enforcing their verification duties.
