Introduction

Artificial intelligence is changing many areas of life, and tax filing is one of them. What used to be a complicated and time-consuming task is becoming easier and faster thanks to technology. One company leading this change is TaxDown, a Spanish fintech startup.

In 2025, TaxDown raised €4 million to grow its AI-powered platform and make tax filing simpler for people in Spain and Latin America. This funding is a major step in their journey to bring smarter, faster, and more accessible tax services to millions of users, especially in areas where tax systems are complex and support is limited.

What is TaxDown?

TaxDown is a Spanish startup that began in 2019. Its goal is to help people file their taxes more easily using artificial intelligence (AI). Instead of filling out forms manually or paying high fees to tax consultants, users can now handle everything online with help from TaxDown’s smart platform.

Key Features of TaxDown:

• AI-powered tax assistant: Automatically fills out forms and gives personalized suggestions.

• Real-time error checking: The system finds and fixes mistakes before submission.

• Government integration: Connects directly with tax agencies to pull user data safely.

• 100% digital filing: Users don’t need to print, scan, or visit offices.

• Maximum refund guaranteed: Helps users save the most money or pay the least tax.

With these features, TaxDown is helping both experienced and first-time filers save time and avoid stress during tax season.

The €4 Million Funding Round

In early 2025, TaxDown closed a new round of funding, raising €4 million. This money will be used to upgrade the platform, hire new talent, and expand into Latin America.

Key Investors:

• JME Ventures – a well-known Spanish venture capital firm

• Abac Nest – a fund focused on startups in Spain and Europe

• Strategic angel investors – experienced people from the fintech world who see potential in TaxDown

These investors believe TaxDown has the right tools to lead the digital tax revolution, not only in Spain but across emerging markets as well.

Where the Funds Will Go

TaxDown has a clear plan for how to use this money to grow and improve its services.

1. Better AI Tools

The team will enhance their AI so that it understands different tax laws in Latin America. This will allow the platform to work in countries like Mexico, Colombia, and Chile without confusion or errors.

2. Market Expansion

TaxDown plans to launch its services in several Latin American countries by the end of 2025. These include:

• Mexico

• Colombia

• Chile

These countries have high populations and growing internet usage, making them perfect places to offer digital tax services.

3. Hiring More Talent

With more users expected, TaxDown will grow its teams in engineering, customer support, and marketing. This will make sure users have fast, helpful, and reliable service.

4. User Education

Many people are not used to filing taxes online, so TaxDown will create guides, videos, and support tools to teach users how the AI works and how to use it safely.

Why Latin America?

Latin America has unique challenges when it comes to tax filing. Many people still do it by hand or rely on accountants. However, not everyone can afford expert help, and the rules are often complicated.

Key Reasons for Expansion:

• Complex tax systems: Many people struggle to understand tax laws.

• Manual filing is common: There’s a lot of paperwork and room for human error.

• Lack of affordable help: Hiring tax advisors can be costly.

• Internet access is growing: More people now use smartphones and can access digital services.

With AI, TaxDown can offer smart tax help to anyone with an internet connection—especially those in rural or low-income areas.

Benefits of Using AI for Taxes

AI in tax services is not just about speed—it’s about making better financial decisions and improving overall efficiency for everyone involved.

For Users:

• Save Time: AI fills out forms in minutes instead of hours.

• Avoid Mistakes: Error detection tools reduce chances of making costly mistakes.

• Get More Refunds: The system finds deductions users may miss on their own.

• Anytime, Anywhere: People can use the platform 24/7 on their phone or computer.

For Governments:

• Better Compliance: More accurate filings mean fewer legal issues.

• Faster Processing: Automated systems speed up approval times.

• Lower Costs: Less need for manual reviews and audits.

• More Data: Governments can collect better tax data for planning and services.

Challenges Ahead

Even though AI can make tax filing easier, there are still challenges to overcome—especially in new markets.

1. Different Tax Laws

Each country has its own tax rules, forms, and deadlines. The AI must be trained to understand and apply these correctly.

2. Data Security

Users will be sharing private financial information, so security is a top priority. TaxDown must ensure strong encryption and privacy policies.

3. Building Trust

Some people may not feel comfortable trusting a machine to handle their taxes. Education and user support will be needed to increase trust.

4. Internet Access

While mobile internet is common in cities, some rural areas still lack good access. This could limit how many people can use the platform.

Global Trends in AI and Fintech

TaxDown is part of a bigger movement where AI is transforming financial services around the world. Some key trends include:

• Personalized finance apps: AI gives users tips based on their spending.

• Automated loan approvals: Decisions made in seconds using smart algorithms.

• RegTech tools: AI helps companies follow rules and avoid fines.

• Chatbots: Virtual assistants handle customer service in banks and fintechs.

TaxDown is taking these trends into the tax world, making them useful for everyday people who just want to file their taxes correctly and easily.

• TurboTax (USA) – The most well-known tax platform in the U.S.

• Taxfix (Germany) – Offers a mobile-first tax app for European users.
