Mexico Proposes a Modernized Alcohol Tax System: A Global Benchmark for Reform

Mexico’s proposed shift to an ad quantum tax system aims to increase revenues, reduce illicit alcohol trade, and align with best global practices.

Mexico’s New Proposal for Alcohol Tax Reform

Mexico is on the verge of implementing a revolutionary reform to its alcohol taxation system. Amid rising pressures for fiscal reforms and global health organizations advocating for more effective alcohol taxes, the Mexican government has introduced a proposal to overhaul its Special Tax on Production and Services (IEPS). This reform seeks to replace the current price-based (ad valorem) tax system with a more transparent, fairer, and efficient ad quantum system. This shift would be a significant step forward in creating a tax regime that aligns with global best practices, particularly in addressing alcohol-related harms.

Key Elements of the Proposed Alcohol Tax System

Mexico’s current alcohol tax regime is based on an ad valorem model, where the tax rate is determined by the price of the beverage. The system levies taxes in tiers based on alcohol content, with higher rates for stronger beverages. The proposed ad quantum tax, on the other hand, would tax alcoholic beverages based on their alcohol content rather than price, creating a more neutral and efficient system.

Here’s a comparison between the existing system and the proposed new system:

The new proposal suggests a tax rate of $1.40 MXN per degree of alcohol per liter, which would replace the current ad valorem tax structure. This would increase baseline revenue and better target the alcohol content, addressing external harms linked to excessive alcohol consumption.

Revenue Implications and Illicit Market Reduction

The shift to the ad quantum system is expected to significantly increase tax revenues. Under the new system, the proposed tax rate of $1.40 MXN per degree of alcohol per liter is higher than the revenue-neutral rate of $1.06 MXN. As a result, total alcohol excise tax collections would rise, which could help fund programs that address alcohol-related health issues, addiction prevention, and societal harms.

The illicit alcohol market is a major issue in Mexico, with nearly 43% of distilled alcoholic beverages sold informally. The current tax regime contributes to this by creating incentives for informal sales, with a resulting annual tax loss of approximately $11.5 billion MXN. The ad quantum system would reduce this informal market by simplifying the tax structure and improving compliance, ensuring that more tax is collected through legal channels.

Why the Ad Quantum Tax is a Better Solution

1. More Neutral:
   One of the major flaws of the ad valorem tax is that it applies different rates to different types of alcohol, incentivizing consumers to choose cheaper products, regardless of their alcohol content. By taxing based on alcohol content, the ad quantum system treats all alcohol equally, regardless of whether it’s distilled from agave, grain, or other ingredients. This neutrality aligns with the goal of reducing alcohol-related harm, which is primarily tied to the quantity of alcohol consumed rather than the price of the beverage.
2. Simpler and More Transparent:
   The ad quantum system is far simpler to administer than the current ad valorem system, which requires a complex network of remitters at every stage of the production and distribution chain. This creates significant compliance and enforcement challenges, leading to under-remission of taxes. Under the ad quantum model, tax remittance would largely be the responsibility of importers and manufacturers—larger, more organized entities that have better capacities to comply with tax laws. This change would streamline tax collection, improve transparency, and likely increase overall compliance.
3. Better Focus on the Source of Harm:
   The most important factor in alcohol-related harms is the quantity of alcohol consumed, not the price. The ad quantum system directly targets alcohol content, making it a more effective tax for addressing the external harms of alcohol consumption. This approach aligns with global best practices, where alcohol taxes are designed to discourage overconsumption while providing funds for programs that help mitigate the societal harms associated with drinking.

The Economic and Health Benefits of the Ad Quantum Tax

The proposed reform could yield several economic and health benefits for Mexico:

• Increased Government Revenue:
  The ad quantum system would increase tax revenue, with the proposal suggesting a collection boost from $38 billion MXN in 2014 to nearly $74 billion MXN in 2023. The higher tax rate on alcohol content is expected to raise funds for health and anti-addiction programs, which could reduce the social costs of alcohol consumption.
• Reduction in the Illicit Alcohol Market:
  By simplifying the tax system, the government can better control and monitor alcohol sales, thereby reducing the size of the informal market. This would ensure that tax revenue is fully collected and that alcohol-related health risks are mitigated through public health programs.
• Healthier Population:
  Well-designed alcohol taxes can serve as an effective tool in reducing excessive alcohol consumption, which is a leading cause of health problems such as liver disease, addiction, and accidents. The ad quantum system would make alcohol consumption more aligned with health objectives, helping to curb overconsumption while funding preventive health programs.

Conclusion: A Global Benchmark for Alcohol Tax Reform

Mexico’s proposed ad quantum alcohol tax system sets the stage for a more effective, efficient, and fair approach to alcohol taxation. The new system would increase government revenue, reduce illicit alcohol trade, and better target the harmful substance—alcohol—rather than its price. If adopted, this reform could make Mexico’s alcohol tax system one of the best-designed in the world, setting a global standard for countries looking to reduce alcohol-related harms and improve tax compliance.
