Revenue has advised me that the person in question was the subject of a compliance intervention in respect of their 2016 tax liabilities. The issues raised during the intervention were subsequently dealt with by the person and fully resolved. Revenue informed the person that the intervention was concluded on 5 September 2018.
Revenue has also confirmed that the person manually filed their 2017 tax return (Form 12) in late January 2019. The return is now processed and Revenue has written to the person setting out their overall tax position for that year. Revenue has also provided the person with direct contact details should they require any further clarification.
