If I set up a promissory note at 0% interest for my company to pay me back $x over 36 monthly payments, is that a deductible expense or is it considered principal only and not deductible by the biz?
If the amount of money you are taking back in installments is equal to the amount you contributed, then I don’t see a tax impact to yourself or to the business. You are just getting a return of principal and principal payments are not deductible…
