Land value tax is a tax that people pay to the government based on the value of the land they own. Land value is the amount of money that someone would be willing to pay for a piece of land if they wanted to buy it. So, if you own a piece of land that is worth a lot of money, you would have to pay a higher land value tax than someone who owns a piece of land that is worth less money. The government collects the money from the tax to pay for things like schools, roads and other public services.
