IRS Audit Triggers: What Raises Red Flags for Taxpayers
Any taxpayer can be frightened by the term IRS audit. Audits are rather rare, but some acts and mistakes might make one more prone to being noticed by the Internal Revenue Service.
Being aware of IRS audit triggers will guide the taxpayers to submit the right returns, minimize the errors, and save costs by avoiding the needless stress caused by the tax season.
This is a simple, clear, professional explanation of what causes red flags and the way the audits are performed.
How Common Are IRS Audit Triggers
