The OECD published its latest edition in its Tax Administration Series, Tax Administration 2021, which sets out key performance indicators for 59 tax administrations which together collect €12.3 trillion of revenue annually. The report provides internationally comparative data on aspects of tax systems and their administration and aims to assist tax authorities in considering how and where improvements can be made in the efficiency and effectiveness of tax administration.

According to the report, tax administrations are investing significant resources in the development of e-services and digital solutions and are embracing opportunities for tracking digital transformation to improve their services, reduce burdens, and improve tax compliance. The report also shows that tax administrations are increasingly using large and integrated data sets, with more than 80 percent using analytics tools and techniques to improve risk management and help design-in compliance.

The report discusses Ireland’s PAYE Modernisation (here, Box 2.4). It outlines that the cornerstone of PAYE Modernisation is the seamless integration of the reporting requirements with the employer’s payroll software and how the changes have brought significant improvements and efficiencies to 180,00 employers and 2.6 million employees and to Revenue.
