<prompt> Human: I live with my boyfriend and his family. My boyfriends family has a home business thats kind of struggling right now so we pitch in to pay bills. I pay the water bill and I like to pay with my debit card and keep receipts so that I can receive medical benefits Im low income. The family wants me to pay in cash instead so that they can claim the business income for taxes. Im assuming they want to write it off Im a noob when it comes to taxes.Im not sure what to do. I think I need the receipts as proof that Im paying a large sum to a utility company. Should I continue paying with my debit card or should I just give in and pay in cash and use that receipt instead? Is there any other beneficial reason for me to not pay in cash?  <response>: Pay with the card. Do not take part in their tax fraud.
