A more thorough explanation:

A tax assessor is a person who evaluates or assesses the value of property for the purpose of taxation. They determine how much a property is worth and how much tax the owner should pay based on that value.

For example, if you own a house, a tax assessor will come and evaluate the value of your house and the land it sits on. They will then use that information to calculate how much property tax you should pay each year.

Tax assessors are important because they help ensure that everyone pays their fair share of taxes based on the value of their property. Without tax assessors, some people might pay too much or too little in taxes, which wouldn't be fair.
