This is a consistent question that comes up time and time again. As a married couple, how should we be assessed and what reliefs are we entitled to?
While this is quite a broad question, here are some key considerations:
You can decide to be assessed as a single person or you can be separately or jointly assessed. More often than not joint assessment makes the most sense.
The married couple tax credit = €3,550 p.a.
So, the amount which a married couple can earn and pay tax @ 20% is €80,000 (where both are earning €40k+ this rate band is typically split 50:50).
Where one spouse is at home (e.g. minding children) then their tax credits and rate band should be be organised in a tax efficient manner.
Residence, Ordinary Residence and Domicile of each individual also requires careful consideration.
Domicile is a complicated concept and with some careful consideration there may be tax planning opportunities. For example, it may be possible for an individual with non-Irish domicile to effectively park capital outside the state and only remit what is required to cover ones cost of living.
