The Haberdashers' Aske's Boys' School Foundation was recently approved to receive grants from the British Schools and Universities Foundation. The BSUF is a charity recognised as a 501.c.3 in American tax law. By giving via the BSUF, American taxpayers can request that the HABS Foundation be a beneficiary of their donation and yet can benefit from tax efficient giving in the USA.
Please look to the BSUF website (http://www.bsuf.org) for further information and for guidance on the form of words to be used in making your gift.
