TIPS ARE CONSIDERED A TYPE OF COMMISSION. SO UNLESS THEY KNOW EXACTLY HOW MUCH YOU HAVE MADE, THEY SHOULD NOT BE TAXING. FOR INSTANCE; IF YOU RECEIVE A TIP AS PART OF A BILL AND THE BOOKKEEPERS CAN CALCULATE THAT THEN YOU WOULD BE TAXED. BUT IF YOU RECEIVE A CASH TIP, THEN NO YOU DO NOT NEED TO BE TAXED ON THIS. YOU NEED TO CONTACT YOU LOCAL BETTER BUSINESS BUREAU AND MAKE SURE WHAT COMMISSION TYPES ARE TAXABLE IN YOUR AREA. EACH CITY IS DIFFERENT BASED ON STATE LAWS.
