Imagine you have a piggy bank where you keep all your money. Every time you get some money, you put it inside the piggy bank to save it for later. When it's time to buy something, you take out the money you need from the piggy bank.
The government is like a big person who also has a piggy bank, but with a lot more money inside. When you work and earn money, the government takes some of it from you to help pay for things like schools, roads, and hospitals. This is called taxes.
Sometimes, people don't pay all the taxes they owe. It's like if you forget to put all your money inside your piggy bank, and some of it falls on the floor. When this happens, the government might take the person's tax refund to help pay the money they owe. A tax refund is like a special gift of money the government sometimes gives back to people who paid too much in taxes.
So, just like how sometimes you have to take out some money from your piggy bank to pay for things you need, the government might take some of the money they owe you to pay for the taxes you owe them. This is called a tax refund interception.
