Revenue Note for Guidance
Where the whole or part of the consideration taken into account in computing a chargeable gain is payable by instalments over a period which exceeds 18 months, the Revenue Commissioners may allow payment of the tax charged on the gain to be spread over a period not exceeding 5 years and not later than the date when the last instalment is due. The taxpayer must satisfy the Revenue Commissioners that payment of the tax in the normal way would cause undue hardship.
