I have a small lawn route, about 20 lawns a week. i do all my lawns with a helper on Saturday because i'm a full time student during the week. i pull in about 1700$ a month, pay my helper about 600$ a month, and have to pay about 150$ in expenses. how much of this do i need to report on taxes? can i keep it all under the table or is this dangerous? if i do report all of this for taxes, can i write off all my expenses if i have all the receipts? thanks for the help.
