TaxDown is a startup that automates income tax filing by calculating regional deductions due to users so they don’t have to navigate complex tax rules themselves.

TaxDown is revolutionizing tax advice, putting on the market a pioneering digital service that allows you to easily file income tax returns, guaranteeing the taxpayer the best result.

TaxDown was founded in 2019 by Enrique García Moreno, Joaquin Fernandez and Alvaro Falcones Muñoz. The company is headquartered in Madrid, Madrid, Spain.


TaxDown has developed a proprietary software/tax language that allows a tax expert with no coding capabilities to translate the tax law into calculation and logic that can be interpreted by their backend seamlessly.


TaxDown leverages the advanced Spanish Tax Agency technology, which offers an API to request the financial data related to a taxpayer — always with prior authorization from the user — with 2.000+ datapoints.


TaxDown is  also making it easier for investors who have sold or traded crypto assets during the past year to file their tax returns. TaxDown managed more than €32M in taxes for users — delivering savings of €4M+ to users.


TaxDown is backed by FJ Labs, Base10 Partners, JME Ventures, Abac Nest, James Argalas (Presidio Union), and others. The company raised €5.5M in Seed extension round on Mar 24, 2022. This brings TaxDown's total funding to €8.8M to date.
