Taxation is not partial slavery because the money is not yours to begin with. What you "earn" is partly due to your efforts, and partly due to you utilizing the infrastructure and institutions built by everyone else. So a part of your "earnings" is society's. That part is called taxes: what you owe to those who enable you to earn.
We can also put taxes on corporations instead of people. Corporations are not humans, and therefore cannot be made slaves.
