The Irish Fiscal Advisory Council is a group of grown-ups who are really good at money and math. They help the Irish government make good decisions about how to spend and save their money. They look at things like taxes, expenses, and debts, and they give advice to the government on how to use their money in the best way possible. It's kind of like when your mom or dad asks you to save your allowance or spend it on something important, like a birthday present for your friend. The Irish Fiscal Advisory Council helps the government make similar decisions, but with a lot more money and math involved. They make sure the government saves enough money for the future and spends money on things that will help the country grow and make everyone happy.
