Dear …
Re: Request for Donation
I applaud you for your efforts in seeking support for __(name of organization or cause)__. It is such a worthwhile cause, which is why it is so difficult for me to turn down your request for donation.
I`m afraid that our company has already committed all the charitable donation funds in our budget for this year. I am sure you can appreciate that we cannot afford to overextend ourselves beyond what our budgeted financial resources will allow.
During the month of __(month)__ each year, we allocate funds in our budget for charitable donations. I encourage you to contact us at that time giving us the opportunity to help out your worthy cause. We look forward to hearing from you then.
Sincerely,
