The EUROMOD-JRC Interface provides a simplified access to EUROMOD itself, and allows analysis of the fiscal and equity impacts of tax reforms. The tool was originally developed by the JRC to be used by experts inside the European Commission network. Since April 2021, the interface is open to any researcher or policy analyst, with the objective of increasing the openness and transparency of EUROMOD and make it accessible to a wider audience.

You will need an EU Login (formerly ECAS) account; in case you don't have one, you will be able to easily create it during the registration process.

The interface utilises the full tax-benefit rules stored in EUROMOD, allowing the user to simulate non-complex reforms on Personal Income Taxes (PIT) and Social Insurance Contributions (SIC) of the European Union Member States, without prior knowledge of EUROMOD. Since June 2021, the tool includes two new features: the estimation of medium-term effects using parameters from a VAR model, and the possibility of running simulations with hypothetical data created with the EUROMOD’s Hypothetical Household Tool (HHoT), instead of EU-SILC based data.

EUROMO-JRC Interface

Currently the interface allows to modify most monetary parameters related to PIT and SIC (for employees, employers and self-employed). For PIT it is possible to change/add/remove rates and brackets, and to modify amounts and thresholds of allowances and tax credits in six categories: (1) personal, (2) family, (3) work-related, (4) housing, (5) education, and (6) health.

The current version of the web interface simulates the tax-benefit systems in force in 2021 based on EUROMOD I4.0+, executed with latest EUROMOD executable. Systems in force in 2018 and 2019, running on EUROMOD I2.0+, and in force in 2020 running on version I3.0+ are also available. Results of the simulated reform are produced using Stata and exported to Microsoft Excel workbooks where several aggregated indicators are summarized.

The EUROMOD-JRC Interface is under continuous development, with the aim of improving users’ experience and provide them with additional simulation options and indicators. For any question or suggestion do not hesitate to contact us at
