WHAT IS SDF'S TAX STATUS? IS MY DONATION TAX DEDUCTABLE? SDF is federally recognised as a tax exempt, non-profit organisation under section 501(c)7 of the internal revenue code. We do not, at the moment, hold a charitable status, as the IRS does not see us as a religious, educational (?), or other charitable organisation. We are viewed as a 'social club' that is supported by its members. Donations to SDF are not deductible beyond a standard deduction. For more information about standard deductions, check the IRS publication included with your tax return form.
