Triggers and Realities of IRS Tax Audits
The Internal Revenue Service (IRS) selects tax returns for audit through either random selection or the presence of suspicious items that deviate from established norms. According to CPA Ryan Losi, audit risk rises significantly with higher adjusted gross income, particularly for taxpayers earning over $1 million, though the probability remains below 1% for those earning under $250,000 (CBS News, 2023). Key red flags include unusually large deductions relative to income, such as substantial charitable contributions or business expenses from sole proprietorships that appear as outliers when compared to peer trend analysis.
Audits are generally subject to a three-year statute of limitations from the filing date, but this extends to six years in cases of substantial understatement of income (25% or more). Tax professionals therefore recommend retaining all supporting records for seven years to prepare for potential examination (CBS News, 2023). Recent congressional budget cuts have reduced the number of trained auditors, lengthening processing times and shifting enforcement focus toward returns with clear discrepancies rather than random selections.
Although increased IRS funding under the Inflation Reduction Act raised public concern about more audits, experts indicate that average taxpayers who accurately report income, including side hustles and cryptocurrency transactions, face minimal additional risk.
