I have a lot of non-profits who have a 990-T for gambling who are generally in the 15% corporate tax rate, they will now be in the 21% corporate rate and only get to use 80% of their NOL's. I find that frustrating because they aren't in the business to make a profit, every dollar they earn goes towards taxes, allowable expenses, and donating to good causes. They already pay more in gambling taxes, federal/ state corporate taxes, and other taxes on their profits than they actually get to donate.
