Say for example I have 3 categories of tax credit, Personal Tax Credit, Dependent Relative Tax Credit and Guide Dog Allowance Credit. Imagine each category is worth €400, so a total tax credit for the year of €1,200 - what should I expect to see in my payslip each month for a tax credit? Will the €1,200 be paid out evenly over 12 months and so I see a tax credit of €100 each month?
