The United Kingdom has opted to leave the European Union, this may make travelling and visiting my holiday home abroad more difficult, or even stop me from working abroad in the future.

My mother is about about to get an Irish passport, as her mother (my grandmother) is Irish. After the paperwork is complete I can also apply for an Irish passport.

Question: What negative things may happen if we get a second passport? I do not want to have to fight in the army, face any tax issues on my savings, nor would I want to lose any of my inheritance money if my mother were to pass on.

Additional info: I am 22, a British citizen with a UK passport, I was born in UK along with both parents. I spend almost all my time within UK, except maybe a short holiday every few years. Currently I am a university student, but in future I will just work an ordinary 9 to 5 job, I do not believe I will operate a business or invest in anything more serious then a few Funds. This also applies to my mother. All our banking is within UK.

  • not your question, but I'm pretty sure nothing stops you from applying for it already. You just need an Irish grandparent. Your mother becoming Irish means nothing for you, only that any kids born from that point on to her or yourself would be able to trace their Irishness back to her. Commented Nov 24, 2016 at 14:15
  • I know that. What I want to know is what might go wrong, for example having to fight in the army?

    The army is definitely a no, Ireland doesn't have conscription, it barely has a military. And I think its just the US that taxes citizens abroad. An actual answer is a bit outside my area though so just added the clarifying comment. Commented Nov 25, 2016 at 14:53

1 Answer 1



Currently there are no real negatives to gaining Irish Citizenship, other than:

  • The cost and hassle of registration on the foreign births register.
  • The Cost of your first passport.
  • Renewal fees for your passport renewals on expiry every 10 years.


According to The Wikipedia article on The Irish Diaspora there are about 3 million people living outside of Ireland with Irish citizenship.

Additionally, the Irish Times indicates that up to 6 million people in Britain could be eligible for Irish Citizenship. (The actual number may be lower.)

Given that Ireland has only 4.7 million residents in the country, they have great infrastructure for supporting citizens abroad.

To answer your specific questions:

Areas which may need investigation

  • I'm unsure of the implications for inheritance tax. I expect that since neither you nor your family would be resident in Ireland it wouldn't be relevant.
  • You might have some complications if you buy Irish Funds, stocks, property, or open bank accounts there. They could have specific rules that cover your situation. However, if you are "just a citizen" but have no other real relationship with the financial/property system you should not have to register with the Irish tax system at all.
