The Iranian National Tax Administration is like a big club where people who earn money have to pay a little bit of their money to the club. This money helps the government of Iran pay for things like schools, hospitals, police officers, and other important things that help the country be a good place to live.
Just like when you play with your friends and everyone puts some money in the middle to buy snacks or toys, the Iranian National Tax Administration takes a small amount of money from all the people in Iran who earn money. It's kind of like a rule that everyone has to follow to make sure the country can keep running smoothly.
The Iranian National Tax Administration has special people who work there called tax collectors. These people go around and visit people who earn money like grown-ups who have jobs or own businesses. They ask them to give a little bit of their money to the club so the government can use it to help make Iran a better place.
The amount of money people have to give to the Iranian National Tax Administration depends on how much they earn. People who earn more money have to give a bigger percentage of their money than people who earn less money. It's like sharing your toys or snacks with your friends based on how much you have.
In conclusion, the Iranian National Tax Administration is like a big club where people who earn money pay a little bit of their money to help the government make Iran a better place. This money is used to pay for things like schools, hospitals, police officers, and other important things that we all need.
