Explanation:

The Inca economy system was based on group work within an ayllu, the economy center. The entire society had to work in order to provide for the community. For the Incas, this was equal to paying their taxes.

Tax work was referred to as the mita, and every citizen had to do whatever the society needed from them such as road building or working the fields. In return they wouldn't have to fear for their basic needs - they would all be met and for free (food, clothes, medical help etc.).
