No they're not. Not exactly fun stuff, tax returns.Tax returns are not usually the source of entertainment.
But they are a primary source of information for those folks who'd like to know how their contributions are being managed, where contributions ultimately go and how much of any organization's assets go directly to the project or beneficiaries intended. Understanding and reviewing the information available is something contributors to any not-for-profit might benefit from doing.
Our tax regulations make these records public specifically for that purpose - organizations that qualify for not-for-profit status benefit from protection from taxation and in return there is a greater degree of public transparency around their finances.
I don't see anyone in this thread treating the USFSA's returns as entertainment.
