My client, a private foundation, is a cash basis taxpayer. On 12/28/2018 the foundation issued a $50,000 check to a non-profit medical organization. On 4/1/2019 the check had still not been cashed. The donee was contacted and they said the never received the check. The original check was voided and a check was issued 4/15/2019 for the same amount.
Question – is the payment on 4/15/2019 considered a 2018 or a 2019 contribution of the private foundation? There is an argument among board members as to when it is deductible. I have looked for something in the Internal Revenue Code and the 990-PF instructions but have not found anything.
