A checklist of other things to consider:
On the home front, make sure all bills are paid or have a means of being paid. If you are retaining a residence while abroad, make sure the rent/mortgage is taken care of and that utilities are being paid while you are away. Insure that important institutions like your bank can reach you.
If you are retaining a bank in your home country, ask about fees for overseas transactions, and if you have a credit card, find out if there are additional fees or any changes you need to make with your account. Inform banking industries that you will abroad to avoid a hold being put on your account.
It is best to inform tax offices of any change in residency. Some countries have reciprocal tax agreements, and others may require you to pay some form of taxes both in your home country and aboard. For more information, refer to our section on "Taxes".
For more information on income tax and double taxation for EU citizens living in another EU country consult the Work & Retirement section of the "Your Europe Information Portal".
The liability for tax in Ireland can be affected by whether you are resident in the country and whether Ireland is your permanent home. There is a specific definition of residence for tax purposes depending on how many days you spend in the country. If you are not resident in a particular year, Ireland can still be your 'ordinary residence' since this term refers to the country where you are usually resident over a number of years. The country that is your permanent home is known as your domicile.
For concerns about your health when abroad, the World Health Organization (WHO) publishes International Travel and Health, which is revised annually and is available free online. Another excellent resource is MD Travel Health, which it provides free and complete travel-health recommendations for every country and is updated daily.
There is no special vaccine requirement for Ireland; however, you may want to check with your doctor whether your vaccinations are up to date. If you have not done so already, consider vaccinating against Hepatitis A and B.
