An IRS audit focuses on verifying the accuracy of reported income, deductions, and credits by reviewing financial records like bank statements, receipts, and invoices. Key areas scrutinized include unreported income (mismatched W-2s/1099s), excessive or unsupported deductions, and high-volume cash transactions. The IRS typically reviews the last three years of filings, looking for compliance with tax laws.
An IRS audit is a review/examination of an organization's or individual's books, accounts and financial records to ensure information reported on their tax return is reported correctly according to the tax laws and to verify the reported amount of tax is correct.
