Hmmm, this is odd. While updating my list of tax related web sites, I stumbled on a site called "irs-fraud.com" which invites people to blow the whistle on tax cheats.
Domain Tools tells me that the site is located in the Antigua Tower in Panama, Panama.
That a tax-fraud reporting site is located in an internaional tax haven is itself quite telling.
You can report tax fraud simply by filling out an IRS form. The IRS site says you need to ship the form to Fresno, Ca.
Hmmm, Fresno is about as bad as any third world nation when it comes to online fraud. I decided not to list this site.
I've actually come across quite a few tax related sites with no address and that use a proxy server to protect the site's owners. I would never give my identity to such a site.
