In the 2015 Budget, one of the measures introduced was an increase in the excise tax on mobile services from 3% to 4%.
If you are a Pay Monthly customer, this tax increase to 4% will feature in your bill as a separate amount.
If you are a Pay As You GO customer, this tax increase is deducted from the amount of credit you get after topping-up, as follows:
€5.00 / €4.81
€10.00 / €9.62
€20.00 / €19.23
