Intentions are always good, but the fact remains that someone aged 67 or 68 who has had tremendous capital gains over a year could create a trust fund and benefit from tax deductions on 70% of the total amount. The charitable organization could then grant, through the trust fund, new deductions to that person. Under those conditions, some annual contributions become subject to tax again. It's a technicality, but it could well become a tax loophole that would allow for major capital gains over time.
