Delivering newspapers question

I know this is not pregnancy or period related but I don’t have Facebook or others to ask so I thought I’d see if any of y’all have any experience in it and can answer my questions

My SO is the bread winner and we are moving and going to be driving our son to school instead of him taking the bus so he can stay in his district for the rest of the year so I just wanted to find a little part time gig that worked around his hours.

So the hours are 2a-7a (8a Sunday’s) it’s 7 days a week, no days off- I know that much and I know u get paid based on your route.

I’m just curious about the ‘self employment thing’ they don’t take taxes out? Do I pay taxes at the end of the year?

Is there any tips or tricks or anything else anyone could tell me to help?

Thanks in advance!
