I am a resident of Canada, and am also an Irish citizen. Recently, I've been considering moving to Ireland (for ~6 months, not forever). During this time, I would either try to get hired on by a local company for the 6 months, or do freelance work for a client in Canada, remotely.
My question to you is if there are any tax issues you can think of in this plan? I assume I'll need to file Irish and Canadian income tax forms for the year that I'm there, since I'll have worked in both countries, but is there anything else I would need to know? I've heard of horror stories where someone is a dual citizen and when they move to their second country, they are suddenly informed that they should have been paying taxes there for years. And also, if you can think of any benefits/drawbacks to either of my options above, that would be great.
