Where someone is getting a lump sum as part of a divorce settlement, is it taxable? I know that any ongoing maintenance payments are taxable as income.
Not sure about Revenue website, probably something on it though, but S.1031 TCA'97 deals with the transfer of assets of divorced persons and S.1026 TCA '97 deals with payments
A lump sum on divorce wouldn't be income, would be a gift. Under certain circumstances it would be tax free.
See Capital Acquisitions Tax Consolidated Acts Section 88.
This should get you to the legislation on Revenue's website: https://www.1822direkt.com/1822central/cms/zinscash.jsp
