At what end do taxes start becoming theft and not owed

As a libertarian, I am against taxes being removed from me and allotted towards things that a higher entity tells me I should be putting the money towards. I’m okay with paying taxes for the roads I use and people that run the community and do things that individuals cannot solely do. Ya know, the reason we have a government. But, at what ends and inclusions do you guys believe tax starts becoming theft? Do you draw the line on state tax cuts to attract large businesses, social security, welfare? Overall, What is the perception of the minimal kinds of taxes we should pay as an individual to contribute to what we consume?
