What was the labor tax all Incas owed?

The labor tax that all Incas owed was known as "mit'a." This system required able-bodied individuals to contribute labor for public projects, such as road construction, agricultural work, and mining, for a specified period each year. In exchange for their labor, the state provided support, including food and shelter, which helped sustain the community and maintain the extensive Inca infrastructure. The mit'a system was a fundamental aspect of the Inca economy and social organization.
