This new scenario directly affects essential metrics such as CPM, CPC, CPL, CPA, and ROAS, regardless of the size of the company or the volume invested in media.
Next, understand what changes in Meta Ads in 2026, why ads will become more expensive, what the new values from Meta are, how the new taxation works, and, most importantly, how your company can prepare to maintain performance and predictability even in this new context.

What is Meta Ads and Why Will 2026 Be a Milestone?
Meta Ads is the advertising platform of Meta, which includes Facebook Ads and Instagram Ads. It is one of the main sources of customer acquisition for companies in Brazil, precisely because it allows advanced targeting, scale, and measurement of results.
With Meta Ads 2026, this scenario changes significantly. After all, it is not just an algorithm or ad format update, but a direct impact on the final cost of paid media, stemming from tax changes.
Meta Ads 2026: What Exactly Changes?
Starting January 1, 2026, Meta will stop absorbing certain taxes that it has always paid internally and will begin passing them directly to Brazilian advertisers. But what does this mean in practice?
- This means that there will be a fixed and automatic increase, with no exceptions, corresponding to an average increase of 12.15% in the final cost of campaigns.
This percentage is composed of:
- 9.25% for PIS/COFINS;
- About 2.9% for ISS.
In other words, the increase from Meta in 2026 does not vary based on the objective, campaign, format, or ad placement. The value is fixed and already defined, making it essential to review certain aspects of the campaign to avoid wasting budget.
If your company invests in Meta Ads and has not yet recalculated the impact of the cost increase in 2026, the Kaizen specialists can help review your strategy before performance is affected.
Why Will Meta Ads Become More Expensive in 2026?
The main reason lies in the changes in Meta's taxation in 2026, driven by the Tax Reform in Brazil. Understand more below!
New Taxes in Testing Phase
Two new taxes will come into play:
- CBS (Contribution on Goods and Services);
- IBS (Tax on Goods and Services).
In 2026, these taxes will have a symbolic rate of 1% in total, just for adaptation to the new regime. At this initial stage, they will not be passed on to advertisers.
Passing on Existing Taxes
The significant impact comes from the passing on of taxes that Meta previously absorbed, such as PIS/Cofins and ISS. Now, with Meta Ads 2026, these taxes will be included directly in the advertiser's invoice.
In practice, the amount displayed in Ads Manager will differ from the amount paid by the advertiser. Therefore, it is crucial to pay attention to this detail.
How Will Meta Ads 2026 Work in Practice?
With the changes, the way costs appear on Meta's platform will also change. Ads Manager will continue to show only the amount allocated for ad placements, without considering the tax burden applied. The taxes will be added only at the time of billing, whether by invoice, bill, or credit card.
This passing on will occur for both advertisers using the post-paid model and those working with prepaid credits.
In practice, this generates two direct effects:
- The amount displayed within the platform does not represent the total that will be charged at the end of the period;
- A portion of the investment will no longer be directed to media and will instead be allocated to tax payments.
In other words, the budget set in Meta Ads does not reflect the real cost of the campaign, nor does it guarantee that 100% of the invested amount will be converted into reach, clicks, or conversions.
The changes in Meta Ads 2026 require technical and financial adjustments. Consulting with a specialized team prevents decisions based on guesswork and protects your media budget.
Practical Examples of the Impact of Meta Ads 2026
To better understand the new values from Meta, see the examples below.
Post-Paid Model Simulation
When setting a monthly limit of R$ 1,000 for campaigns, this will be the amount displayed in Ads Manager as media investment. However, it is essential to be aware of the invoice closing, as taxes will be added separately.
Thus, the total expenditure for the company will be around R$ 1,138.30.
Pre-Paid Model Simulation
In the case of advance payment, when adding R$ 1,000 in credits, the system automatically deducts the taxes from this amount. In practice, about R$ 878.50 will be effectively allocated for ad placements, while the remainder corresponds to the applied tax burden.
Now imagine this impact on companies investing R$ 10,000, R$ 50,000, or R$ 100,000 per month. The more expensive Meta Ads in 2026 completely alters financial predictability, doesn't it?
Which Metrics Will Be Impacted by Meta Ads 2026?
The increase from Meta in 2026 directly affects the main performance indicators, as:
- CPM, CPC, CPL, and CPA increase;
- ROAS tends to decrease if the company does not adjust the campaign strategy.
Thus, the same budget will generate fewer impressions and fewer conversions. Therefore, there is a greater risk of budget overruns, as Ads Manager does not show the taxes. In practice, we can say that these impacts require an immediate change in how to plan campaigns.
Does Meta Ads 2026 Require a New Paid Media Strategy?
Yes, because companies that maintain the campaign structures they used until now will feel the impact much more aggressively. Thus, with Meta Ads 2026, it is not enough to invest more. It is necessary to invest better to achieve good results from this change.

What Are the Main Recommendations to Face Meta Ads 2026? Expert Tips!
Some actions become indispensable from now on:
- Review of budgets and real CAC: the real customer acquisition cost needs to be recalculated considering the taxes. Ignoring this compromises margins and goals;
- Focus on more qualified audiences: therefore, prioritize remarketing campaigns, proprietary audiences, and high-precision lookalikes, as these techniques reduce budget waste and improve ad performance;
- More efficient creatives: high-performance pieces help reduce CPC and CPA, compensating for part of the increase;
- Adjustment of the mix of objectives: not always will direct conversion be the best path. In many cases, working on consideration before conversion improves campaign results;
- Daily monitoring of metrics: it is essential to closely monitor metrics such as CPL, CPA, ROAS, and LTV.
In summary, companies that do not adapt to Meta Ads 2026 are likely to see their costs grow rapidly, with a drop in performance, which directly impacts conversion.
Does Meta Ads 2026 Affect Companies of All Sizes?
Yes. The adjustment will be applied automatically to all advertisers in Brazil, without exceptions. Thus, small companies feel it in their cash flow, medium companies feel it in scale, while large companies feel it in efficiency and ROAS. Therefore, strategic planning becomes essential.
What Is the Importance of a Performance Specialist Agency?
As we have seen so far, improvising in Meta Ads 2026 can be costly. The new reality demands:
- Financial planning;
- Intelligent media strategy;
- Integration between marketing and finance;
- Continuous campaign optimization.
This is precisely where a performance specialist agency makes a difference, adjusting strategies, creatives, audiences, and budgets to maintain sustainable growth even with the increase from Meta.
