The local property tax (LPT) is annual self-assessed tax charged on the market value of all residential properties in Ireland. It came into effect on 1 July 2013 and is collected by the Revenue Commissioners. The tax is assessed on residential properties. The owner of a property is liable (though in the case of leases over twenty years, the tenant becomes liable). The revenue raised is used to fund the provision of services by local authorities and includes transfers between local authorities.
