The business cannot use a round up charity donation for a tax deduction. They act as a holding agent. It’s not counted toward their income nor does the donation affect their income tax. You as the customer donating are the only one eligible to claim it for tax deduction, though it’s usually way too low to be worth the effort.
A reasonable criticism is that they will often on the PR side spin it as money they have raised, not always emphasizing how much customers are responsible for rather than them.














They shouldn’t, but it would not surprise me if many especially smaller businesses have claimed customer cash donations as their own. Not sure how charitable the government would be with them if it was noticed, though.
