Need some help

i’m 15 and want to get into the job section where people pay you for stuff. And I was wondering if anyone knew what kind of work it is because for certain things I need a work permit (I live in missouri). Is it freelance? and also does anyone know how taxes for minors work. I read somewhere that if I make less then ~1000 a year then I don’t have to do taxes but it is my parents paypal so do they have to pay no matter what?
