So, rather than paying capital gains taxes to the IRS you are willing to pay almost the same amount to this company as their transaction fee?
I don’t see how this really benefits you if the profit to be shielded is a modest amount (less than $100K), and only of marginal benefit for larger amounts up to $1MM.
It may be that I am a little dense, here, but I just don’t get how the money returned to you by the trust is not taxable income in some fashion which seems to negate the tax benefit of the charitable deduction.
