If you have marketable securities that have appreciated in value, the current tax laws make it possible for you to make a gift at a lower after-tax cost.
A gift of appreciated securities generally qualifies you for an income tax charitable deduction equal to the value of the gifted securities, and it avoids the long-term capital gain tax on your unrealized capital gain.
Usually a sale of appreciated securities results in a tax on your full gain – in other words, you keep only part of the profit. But if you give those same appreciated securities to the PTA of PS8, there is no tax on your gain even though your “profit” is counted as part of your charitable deduction.
Please contact your tax advisor for guidance on your particular situation.
