I am a college kid and have around 47 lawns that I mow. (I live in minneapolis and go to the U of M so im able to start mowing in the spring and finish in the fall) As of right now i dont have an actual registered business, and i do not pay taxes. I am wondering the legalities of not having a registered business? Will I eventually get in trouble with The IRS? I also work part time in the winter at my school so i can record some income. But I also do use most of the profits from lawn mowing to pay for school.
