Getting married or entering a civil partnership in Ireland can have a profound impact on your tax situation. Revenue offers three ways for couples to be assessed: Joint Assessment, Separate Assessment, and Separate Treatment.
Joint Assessment is the default and usually the most beneficial option. It allows couples to transfer unused tax credits and standard rate bands between each other. If one spouse earns significantly less than the other (or stays at home), the higher earner can utilize some of their partner's standard rate cut-off point, pushing more of their income into the 20% bracket.
It's important to note that you cannot transfer the entire standard rate band. There is a cap on the maximum standard rate band applicable to the higher earner. Similarly, certain credits, like the Employee Tax Credit, cannot be transferred.
You should inform Revenue as soon as you get married. In the year of your marriage, you continue to be taxed as single people. However, if the tax you paid as two single people is greater than what you would have paid if jointly assessed, you can claim a 'Year of Marriage' refund the following year.
