Stamp Duty and the National Stamp Duty Office

Stamp Duty is a duty charged on certain written documents (known as "instruments"). Not every instrument is liable to stamp duty. To be liable an instrument must be listed in Schedule 1 to the Stamp Duties Consolidation Act 1999. It must also be executed in Ireland or, if executed outside Ireland, it must relate to property situated within Ireland or something done or to be done in Ireland. Some instruments may benefit from an exemption or relief.

The various categories of instruments within the charge to stamp duty are listed in alphabetical order (each category being known as a "Head of Charge") in Schedule 1 to the Stamp Duties Consolidation Act 1999. The rate of duty applicable, which may be ad valorem or fixed, under each Head of Charge is also set out in Schedule 1.

Stamp duty is a self-assessment tax payable by the "accountable person" (e.g. the purchaser or transferee in the case of a transfer of property, the lessee in the case of a lease).

Where an instrument is liable to stamp duty, a stamp duty return must be filed on-line with Revenue via the e-stamping system. The e-stamping system allows filers to use ROS (Revenue On-Line Service) to file returns and pay duty on-line. Filers must be registered to use ROS. Information on how to: Register for ROS.

The full amount of stamp duty due must be paid within 30 days of the date of execution of the instrument. In practice Revenue allow a further period of 14 days in which to file an e-stamping return and pay the duty. Failure to file and pay within 44 days will result in late filing and interest charges.

Tax reference number and tax type queries

To complete an e-stamping return the tax reference number of each of the parties to the instrument plus the tax type for which they are registered with Revenue are needed. Filers should ensure that they have acquired all the necessary details to complete the e-stamping return from the accountable person preferably before the instrument is executed and in any event well before filing: otherwise there is a real risk that late filing and interest charges will arise.
