Minimum Income Probes
For nonbusiness returns, an agent question the taxpayer or representative about possible sources of income other than reported on the return. If there is no other information in the file indicating potential unreported income, the minimum income probe is met.
For taxpayers who are self-employed and file a Schedule C or F, an analysis is made of tax return information to determine if reported income is sufficient to support the taxpayer’s financial activities.
