Payroll Audit Checklist
Prepare for payroll audits with a systematic approach covering documentation, calculations, and compliance. This checklist helps you organize employee files, verify tax withholdings, reconcile quarterly filings, and test internal controls. Covers everything auditors examine including timekeeping accuracy, benefit deductions, wage calculations, and tax deposits. Most audit failures happen from missing documentation, not actual errors. Track 12 critical areas from system setup to post-audit remediation. Used by accounting teams managing payrolls from 25 to 500+ employees across manufacturing, healthcare, and professional services.

How the Payroll Audit Checklist works
Enter your company size, payroll system type, and last audit date. Specify your state tax requirements and any union agreements. The system generates audit preparation tasks organized by timeline and priority. Get specific documentation requirements, testing procedures, and reconciliation schedules. Includes sample audit trails, variance analysis templates, and compliance verification steps. Track completion across departments and generate audit-ready packages.
Payroll audit findings cost companies an average of $18,000 in back taxes, penalties, and professional fees. About 40% of small businesses incur IRS penalties each year for payroll errors. This checklist reduces audit prep time from 3 weeks to 5 days by organizing documentation systematically. Prevent compliance issues that trigger investigations and protect your reputation with government agencies and employees.
