TaxDown Secures €4M Investment to Expand AI

Madrid-based fintech company, TaxDown, has successfully raised €4 million in a recent funding round led by Bonsai Partners. This capital infusion will fuel the company’s strategic initiatives to enhance its artificial intelligence (AI) capabilities and broaden its reach across Spain and Latin America, simplifying the tax filing experience for individuals and businesses.

This latest round of funding also benefits from continued support from existing investors, including Base10, JME Ventures, and 4Founders. The investment arrives at a crucial time for consumer-facing platforms, where profitability and operational efficiency are paramount for sustainable growth.

Enrique García, CEO and co-founder of TaxDown, emphasized the company’s focus on efficient scaling: “We don’t prioritize raising massive funding rounds as the sole measure of success. Our business model demonstrates that efficient operations, AI-driven scaling, and profitability are achievable without needing hundreds of millions in investment.”

Founded in 2019, TaxDown has rapidly become a leading digital solution for personal income tax filing in Spain and, more recently, Mexico. The company’s core strength lies in its unique combination of a proprietary AI tax engine and a team of over 200 human tax experts. This system is designed to simulate millions of tax returns, automatically identifying and applying all relevant deductions to maximize user benefits.

García further elaborated on the role of AI within TaxDown: “Artificial intelligence empowers us to achieve rapid growth and scale our operations cost-effectively. We process vast amounts of data with a degree of personalization that was previously unimaginable. AI doesn’t replace the human expert; it amplifies their abilities.”

TaxDown exemplifies a growing trend in fintech and productivity startups, where AI is deeply integrated into core operational processes rather than merely added as an extra layer. The company utilizes AI-powered tools to assist tax advisors with tasks such as document filtering, error detection, automated communications, and staying updated on evolving legal regulations.

Bonsai Partners, known for backing successful Spanish digital consumer companies such as Wallapop, Idealista, and Glovo, recognizes TaxDown’s potential.

Javier Cebrián, General Partner at Bonsai Partners, stated, “We are excited to invest in TaxDown at this pivotal moment, as their services gain significant traction in Spain and Mexico, driven by the increasing efficiency provided by their AI technology.”

With the new funding, TaxDown aims to strengthen its AI team, introduce a virtual advisor to enhance user personalization, and maintain its current team structure. The company has established key partnerships with major financial institutions like Santander and Revolut, enabling millions of users to access its tax services directly through their banking apps.

TaxDown’s international expansion began successfully in Mexico, where its user base has grown fivefold in the past year, now serving over 1.5 million users. The company plans to continue expanding throughout Latin America, addressing the complex and often challenging tax filing processes for individuals in these markets.

García concluded, “The adoption rate in Mexico has been exceptional. We are now focused on expanding throughout Latin America, bringing our advanced technology to millions who currently lack access to simple and reliable tax filing tools.”
