As the Deputy will be aware, no data in respect of 2018 will be available to Revenue until the corporation tax returns for accounting years ended in 2018 are filed, processed and analysed. I am advised by Revenue that the latest available information is from Corporation Tax returns for 2016, which indicate 11 companies claimed the Knowledge Development Box with a tax cost of €9 million. Information in respect of 2017 will be published during 2019, when returns for the year have been processed and analysed. Information in respect of 2018 will likewise be published during 2020.
