How to Prepare for a Compliance Audit

Build audit-ready documentation systems and processes to minimize compliance risk and reduce audit costs for your business.

  1. Map your compliance obligations by revenue threshold. List every regulation that applies to your business: tax compliance, labor law, industry-specific rules, data protection requirements. Note which obligations trigger at specific revenue levels ($100K, $500K, $1M+). Create a calendar with all filing deadlines, renewal dates, and required reporting periods.
  2. Centralize documentation in audit-ready folders. Build digital folders for each compliance area: financial records, employee files, contracts, licenses, insurance policies. Use consistent naming conventions with dates. Keep current-year and prior 3-7 years accessible (varies by regulation). Back up quarterly to separate systems.
  3. Run monthly internal compliance checks. Review payroll tax deposits, sales tax filings, and required postings monthly. Check that licenses and permits are current. Verify employee I-9 forms and safety training records are complete. Document any gaps immediately and create remediation timelines.
  4. Prepare standard audit response procedures. Designate one point person to handle auditor requests. Create a document request log to track what's provided when. Set up a clean workspace with power, internet, and printer access. Budget 20-40 hours of staff time for typical audits, more for complex reviews.
  5. Review financial controls and approval processes. Document who can authorize expenses, sign contracts, and access financial accounts. Implement segregation of duties where possible: different people should handle cash, record transactions, and reconcile accounts. Keep written policies for expense reimbursement, procurement, and financial reporting.
  6. Calculate audit defense budget and insurance coverage. Budget $5,000-$25,000 for professional representation during significant audits. Review your business insurance for audit defense coverage or regulatory investigation protection. Keep 3-6 months of operating expenses accessible for potential penalties or required remediation costs.
