TaxAdmin.AI

Open-access repository of the use of AI by tax administrations in the EU

Antwerp Center On Responsible AI

Our mission

TaxAdmin.AI is an open-access repository, compiling artificial intelligence algorithms used by tax authorities in the EU. The goal of TaxAdmin.AI is to inform citizens on the algorithms used to assist, surveil and profile taxpayers.

The website follows a citizen-science approach, allowing every visitor to contribute to this research by reporting useful additional or new information.

Transparent information on algorithms of the tax administration

The TaxAdmin.AI team performs regular sweeps through the internet, and publicly documented use of AI by tax administrations: what functions they perform, what taxpayer data is processed, whether these are regulated by specific norms, and what are the consequences for taxpayers.

Upon identification of a new AI system, we publish the system in the EU Overview and in the individual country reports.

Systems identified are classified in a functional taxonomy, and placed into one of the following categories:

EU Overview of AI tax algorithms

Since 2004, Tax administrations in the EU are increasingly making use of machine-learning to perform their fiscal prerogatives. Our interactive map provides an overview of the EU Member States who use AI and the different models leveraged in the EU.

Individual Country Reports

Machine-learning is used to collect taxpayer data, to visualize networks, to detect risks of fraud, or to segment taxpayers into categories of risks. Each report describes which types of AI systems are used in an EU Member State, the functions performed by the models, and whether these are subject to specific legal norms.

Publications

Despite being fairly recent, and fairly niche, the use of machine-learning by tax administrations has already been the subject of several litigations in EU Member States. These important cases are shaping the future of tax algorithmic governance in the EU.

TaxAdmin.AI is the project of David Hadwick, PhD researcher at the DigiTax Centre of Excellence of the University of Antwerpen (Belgium) and PhD Fellow in legal fundamental research at the Research Foundation for Flanders (FWO). David is a member of the Antwerp Centre for Responsible AI (ACRAI) and the Antwerp Tax Academy (ATA).

David Hadwick carries research on the use of technology by tax administrations, at the intersection of law, technology and public governance. His current research: ‘Deus Tax Machina: The use of AI by tax administrations and its implications for taxpayers‘ fundamental rights in the EU‘ maps the use of tax machine-learning algorithms in the EU, and examines the consequences of such use on taxpayers’ rights.

TaxAdmin.AI is a citizen-science repository compiling all AI/machine-learning algorithms used by tax administration in EU Member States.

The goal of the website is to provide EU citizens with an easy-to-use exhaustive database of the machine-learning algorithms used by tax administrations.

In doing so, TaxAdmin.Ai hopes to educate citizens on the use of technology by tax administrations and promote transparency over an important but otherwise relatively unknown topic.

TaxAdmin.AI regularly performs ‘sweeps’ through the internet, and systematically analyse content which makes references to cases of AI/machine-learning algorithms used by EU tax authorities.

This can be literature of the OECD, IOTA, CIAT or incidental reports in national or local newspapers.

After having identified algorithms, we compile them in our EU Overview and in our Country Reports.

TaxAdmin.AI is a citizen-science repository, which follows a citizen-science approach where every visitor to contribute to this research by reporting useful additional or new information.

Should you have information on other AI tools used by tax administrations, feel free to contact us and we will publish your information on the website.

Anyone with documented sources on the use of AI by tax administrations, in any language, can share it with us and actively contribute to the TaxAdmin.AI project.
