IRS Audit
An IRS audit is an official examination of a taxpayer's financial records, tax returns, and supporting documentation to verify that income, deductions, credits, and other tax positions comply with applicable U.S. tax law. Audits are conducted through three primary channels: correspondence audit (by mail, for narrow issues), office audit (at an IRS field office, for more complex matters), and field audit (at the taxpayer's place of business, reserved for the most complex returns). Selection is triggered by statistical anomalies identified by the IRS's Discriminant Information Function scoring system, by mismatches between reported income and third-party information returns, or by random sampling.
Problem & Application
A short-term rental operator receives a correspondence audit notice questioning $38,000 in Schedule E deductions. The IRS flags two items: $14,000 in repair and maintenance expenses (the agent suspects some are capital improvements) and $12,000 in depreciation (the property's cost basis may not be supported). The operator needs to produce receipts or invoices for every repair, a depreciation schedule tied to the original closing statement, and a clear allocation between personal and rental use days if the property was used by the owner. Without organized records -- ideally reconciled monthly rather than reconstructed at audit time -- the operator faces potential disallowance of deductions and assessment of back taxes plus interest. Properties operated through an LLC or S corporation face additional scrutiny on salary versus distribution splits and on reimbursements to owner-employees. Maintaining a dedicated business bank account, categorizing expenses in real time, and retaining documentation for a minimum of several years are the baseline defenses.
In Short
An IRS audit, while stressful, is a routine part of tax compliance enforcement. Proactive, accurate tax filing, supported by solid documentation and professional guidance, reduces audit risks and ensures smoother resolutions if one occurs.
