Typically, the courts give the IRS wide latitude to enforce summonses that may uncover information regarding potential tax evasion. The IRS doesn’t need “probable cause,” or even “reasonable suspicion,” like the police might need to investigate a crime. Rather, under federal law, the IRS has the power to examine any data that may be relevant to determining the correct tax owed by any taxpayer.
