While I know it is the political things to do - giving to the United Way. The sure fire way is to give directly. In our community the United Way pockets about 10-12% of all donations and only about 40% of the remaining funds go directly to non-profit organizations and the rest now funds "special projects".
One other thing you can do is put restrictions on your donation re use for benefit of low to moderate income beneficiaries/groups that help low to mod....and then obtain follow up documentation that your requirement was followed. Never just give the money and hope for the best. Put some strings on it. It is a little more work up front but saves a made scramble during an exam as you have everything you need.
I believe 2 years after 9/11, 50% of the $1,000,000,000 donated immediately after the attack was still sitting in accounts instead going to the intended recipients. The United Way rep has never been able to give a good answer to my questions on that - and I have not given them any money since that day.
All digression aside, the bank has always reported the United Way dollar contributions and volunteer time and has not run into any issues...yet.
