Imagine the government needs to fix something but also wants to buy fun things like new schools and roads.
They need to find ways to pay for those things without making people pay more in taxes.
The Chancellor, Rachel Reeves, has a special plan to make more money available for the good things by changing some rules about how much money the government can borrow.
This special plan won't mean no more taxes, but it might help keep them smaller so people don't have to pay as much!
