<prompt> Human: We are not married. We live together and our paychecks go to our joint checking. We verbally agreed to give x amounts to various charities.  <response>: Charitable donations only count if you itemize your deductions, so it might make more sense for one of you to itemize and claim all the donations, while the other claims the standard deduction. If neither of you dont have enough deductions anyway, then it really doesnt matter, just take the standard deduction and dont worry about who claims what donation.
