InformationGenerally you will be charged Irish tax on your world-wide income earned or arising in a tax year during which you are resident, ordinarily resident and domiciled in Ireland for tax purposes.
For any tax year during which you are non-resident and not ordinarily resident in Ireland you will be charged tax on your income from Irish sources only. The extent of your liability to Irish tax may also be influenced by your domicile status and possibly by a double taxation agreement.
In addition to income tax, social insurance (known in Ireland as 'Pay-Related Social Insurance' or PRSI) and, where applicable, a 2% health contribution are also deducted through the tax system by employers or paid to the Revenue Commissioners directly by the self-employed.
Residence status Your residence status for Irish tax purposes is determined by the number of days you are present in Ireland during a given tax year. You will be resident in Ireland for a particular tax year in either of the following circumstances:
A "day" for residence purposes is one on which you are present in Ireland at midnight
It does not matter if you come and go several times during that tax year or if you are here continuously. A count is made of the total number of days you spend in Ireland for any purpose in each tax year.
If you are ordinarily resident and with an Irish domicile all your Irish /foreign sourced income will be taxable in full. Exceptions are made for income from trade, profession,, office and employment, all the duties for which are exercised outside Ireland. In addition other foreign income, for example, invested income, is also exempt, provided it does not exceed a set amount in the tax year in which it is earned.
Every individual acquires a domicile of origin at birth. A domicile of origin will remain with you until such time as you acquire a domicile of choice. However before a domicile of origin can be shed there has to be clear evidence that you have a positive intention of permanent residence in another country and have abandoned the idea of ever returning to live on your country of birth.

If your income is taxable in Ireland and in a country with which Ireland has a double taxation agreement, a double charge of tax is prevented under the agreement by either:
The precise treatment of your income will depend on the details of the particular agreement, the nature and source of your income and, in some cases, on your nationality /citizenship.
If the income arises in a country with which Ireland does not have an agreement, the amount of tax in Ireland will be the net amount received by you after the deduction of the foreign tax paid. There is no credit available for foreign tax paid against your Irish tax liability on the same income.
In order to work, you require a Personal Public Service Number (PPS No.). You can obtain a PPS No. (or ask for your old number, if any, to be traced) at your local social welfare office.

Further information on how to obtain a PPS number is available from the Department of Social and Family Affairs. This information is also available in Personal Public Service Number - Code of Practice issued by the Department of Social and Family Affairs.
