Starting January 1, 2026, Google and Meta will adopt a new billing model for paid ads. This change directly affects how investments are billed and requires more attention in media planning to avoid surprises in the final amount.
In this article, we explain what has changed, how it impacts practice, and how Kaizen is working to ensure transparency and control for its clients.
What has changed in ad billing?
Previously, many advertisers considered only the amount set as the campaign budget. With the new update:
All charges will now include the campaign amount + taxes
The invoice, ticket, or bill will already come with taxes included
In Ads Manager, the displayed amount will still be only the campaign budget, excluding taxes
In other words: the amount that appears on the platform is not exactly the final amount charged.
Impact on post-paid accounts
For accounts with post-paid payment, the change goes beyond the final charge. Taxes will also influence:
The bid/offer set in the ads
The daily spending limit
This means that even maintaining the same configured budget, the financial consumption may be higher than expected.
What does this mean in practice?
In practice, the total amount invested may exceed the initially planned budget.
Example:
If the defined monthly investment is $1,000, the final cost may reach approximately $1,138.30, considering the incidence of taxes.
This difference can impact:
Financial planning
Monthly investment forecasting
Media cost control
Therefore, strategic monitoring becomes even more essential.
