We are hoping to setup a system that would allow donors to opt in to slightly increase their donation to help cover credit card fees for online donations. We have a solution in place that will do this, but now our only concern is the financial side of it. The system would only alter the donation amount, but all the money would still be going towards the same fund and still count in the donor's overall tax-deductible donation amount. But our concern is that if we actually word it on the website that the increased amount is to offset credit card fees or to cover operating expenses, would we be expected to pay taxes on that amount, or can we still count it as just a "donation." We are a university organization as well, so if anyone wanted to share their experience with doing this, and what processes you have in place to comply with your university or Department of Revenue policies; then we would appreciate it.
