Q: I have been told that it is possible for us to form a Family Foundation, register it as a donor organization with the Receiver of Revenue for tax deductions for donations.  As the taxes we pay are used in un-Islamic ways by the Govt., e.g., abortions, corruption, mismanagement of funds, etc, it is better for us to pay as little tax as possible.  Since the donations made by the Foundation are tax deductible, it is a way in which Muslims can minimize their tax burden in a legal way when Zakaat is paid.
