A cryptocurrency investor from Killorglin has had to pay over €155,000 in a tax settlement to the Revenue Commissioners.

Revenue says the case arose after it found that Desmond O’Keeffe, of 51 Knocklyne Valley in Killorglin, had under-declared capital gains tax linked to cryptocurrency investments.

Mr O’Keeffe had to pay a total settlement of €155,030, made up of over €98,000 (€98,442) in tax, €27,000 (€27,056) in interest, and almost €30,000 (€29,532) in penalties.

Revenue identified the capital gains tax underpayment after a Level 2 Compliance Intervention, a formal compliance check that is less serious than a full audit but more detailed than a simple Level 1 Compliance Intervention.

The case is included in Revenue’s latest list of tax defaulters, whose settlement cases were agreed between 1 October and 31 December 2025.

The Revenue Commissioners say settlements are published when the extensive voluntary disclosure options are not availed of, and the default arises because of careless or deliberate behaviour.
