<prompt> Human: Hey PF,I recently moved to San Francisco and I live in the main two floors of my landlords primary residence with three other friends. She lives on the ground floor of the house. She also runs a non-profit that has 501c3 tax-exempt status. I am very curious to know if there is a way to legally direct my rent payment in a way so that we can consider it a charitable donation while maintaining her ability to live off our rent payments. I am under the impression that my roommates and I solely fund her income from rent money.I managed to find her filing for the Fictitious Business Name under public records and she has filed it to a P.O. Box which is not allowed on the registration form. Did the office just not catch this or am I missing something? She is supposed to register the organization to her residential address which would be the same as ours, although she has added a 12 to the address to separate our mail. Am I on to something here or is this impossible?Thanks  <response>: Nope. A donation cant be with the expectation of something of value to yourself. Even if you could do this, the amount you benefit from in rent would be taxable - just like if you get one of those free t-shirts for donating to a charity, they deduct the value of that from your contribution.
