The IRS Whistleblower Office has been clear about what it wants to see in Form 211 submissions from whistleblowers.
Be specific. Be specific about who is the taxpayer(s) – name, address (EIN, SSN if you have them). If it is a major company – the specific division, subsidiary at issue. Be specific as well – what is the tax issue? The IRS shouldn’t have to guess or piece together what is the tax issue.
Be credible. Provide credible information based on your own knowledge and awareness. In short, the IRS is happiest when you have first-hand (insider information even better) knowledge of the taxpayer and the tax issues. Credible – having documents that support your position (or, at least, can point the IRS to the key documents). Credible – you have a background in the tax issue (example, knowledge in tax).
Be current. Information that is about recent and ongoing tax evasion is the ticket. Stories about tax evasion from 2010 . . . eh (unless involving failure to file or undeclared offshore accounts). The IRS is interested in matters where the tax years are still open.
The IRS is also particularly interested in hearing about emerging issues – something that is new to them – both a tax scam but also a taxpayer(s) that has not been on their radar. In addition, given the drumbeats here in D.C., the IRS will certainly be interested in information about wealthy individuals evading tax.
