Stock Transfers, Planned Giving & Currencies

The gifting of securities is a “win-win” situation for you and for us. Instead of incurring a capital gain tax on appreciated securities, transferring stock to Green Map qualifies the full value as a tax deductible charitable contribution. Or, you can create a legacy by including Green Map System in your will. Ask us for details. Contact us directly about making bank wire transfers in any currency, too.
