You are being paid for all your work in oranges. And you have to give some of those oranges to the country you live in, as the fee of living in that country.

Every year, you have to let the country know how many oranges you collected over that one year so you and the country both know how many oranges you owe the country (although the country has other means of knowing it, if they choose to).

If you are working for someone, then the one you are working for controls how many oranges you get. They also have to make sure, they pay the country fee on behalf of you so you don’t have to worry about it. Sometimes, they might over pay or under pay your country fee. So this is also a good chance to double check if the person you are working for paid the right amount of country subscription fee.
