I was applying for tax clearance reference number today. Myrevenue.ie indicated an issue with CGT in tax year 2019. I have no capital gains to disclose for that period ? Tried ringing their 1890 number but only to get a recorded message saying they are unable to take calls at present due to Covid-19. No email address that I can find to address a query to either. Do I just file a CGT return for 2019 declaring nothing to declare or send an email to that effect or what ? Tax clearance needed for HAP purposes.
