Does the IRS allow you to earn a salary working for a 501 public?
My first thought was Why not? Then I thought that maybe your donation was to a family charitable foundation that you control, and you are paying yourself with money that you had previously donated and taken a deduction for. But when you earn the salary, it is taxable income, so it may be a wash. In some ways it is similar to a self-funded retirement account: You shift the income to a later year, when you may have a lower marginal tax rate. A bigger question is this: Is the salary you take a noticable portion of the disbursements for the charity? If so, it may be considered abusive, and the charity may be penalized. I am not a tax lawyer, but these would be the issues that I see.
