How Do I Prepare for a 1099 Independent Contractor Audit?

Quick Answer

Preparing for a California 1099 independent contractor audit involves four workstreams: (1) compiling contractor documentation (agreements, invoices, business licenses); (2) applying the ABC test to each contractor; (3) identifying AB 2257 exemptions where applicable; and (4) reconciling 1099 totals to payroll and tax records. The short version is that EDD auditors examine every 1099 contractor for potential reclassification. Organized documentation demonstrating ABC test satisfaction or AB 2257 exemption is the primary defense.1

Quick Reference

Jump to: documentation, ABC, AB 2257, or reconciliation.

1. Documentation Compilation

Compile contractor agreements, invoices, business licenses, and insurance certificates.

If this is you: Systematically organize per-contractor file. Written agreement, W-9, business license, insurance, invoicing. Organized files demonstrate business structure.

Documentation Steps

  1. Gather contractor agreements.
  2. Collect W-9s.
  3. Request business licenses.
  4. Gather insurance certificates.
  5. Organize by contractor.

2. ABC Test Application

Apply ABC test to each 1099 contractor.

If this is you: Per-contractor ABC analysis. Element A: control? Element B: outside usual business? Element C: independent trade? All three required.

3. AB 2257 Exemption Identification

Identify which contractors qualify for specific exemptions.

If this is you: Check each contractor against AB 2257 exemption list. Qualifying contractors use Borello test instead. Document exemption basis.

4. 1099 Reconciliation

Reconcile 1099 totals to payroll, bank records, and tax returns.

If this is you: Ensure 1099 totals match bank disbursements. Federal/state mismatch is a red flag. Reconcile systematically before EDD asks.

Frequently Asked Questions

How do I prepare for a 1099 independent contractor audit?

Four workstreams. Compile contractor documentation (agreements, licenses, insurance). Apply ABC test per contractor. Identify AB 2257 exemptions. Reconcile 1099 totals to payroll and tax records. Systematic preparation improves audit outcome.

What documents should I have for each contractor?

Written contractor agreement. W-9. Business license or LLC formation. Professional liability insurance. Invoicing records. Marketing materials showing contractor markets to other clients. 1099-NEC issued.

Should I have written contractor agreements?

Yes. Written agreements are essential evidence of contractor relationship. Unwritten contractor arrangements are presumed employee relationships in California post-AB 5.

What should my contractor agreement contain?

Scope of work. Fee structure. Independence provisions. Right to work for others. No integration into hiring entity’s usual business. Self-direction provisions. ABC-compliant language.

Can I use a generic contractor template?

Cautiously. Generic templates miss California-specific ABC requirements. Custom-drafted agreements with counsel are better. Post-AB 5, generic templates have been found insufficient.

What if I don’t have a written contract with past contractors?

EDD audit risk higher. Document the relationship retrospectively. Assess whether the actual relationship supports contractor classification. Engage counsel for material exposure.

Should I keep all 1099 records?

Yes. Minimum 4-year retention. California requires payroll record retention under Labor Code. 1099 records, contractor agreements, and supporting documentation should all be retained.

How do I reconcile 1099s to payroll?

1099 totals should match bank disbursements to contractors. Should not overlap with W-2 employees. Total 1099 spending should reconcile with tax returns. Mismatches are audit flags.

Do I need contractor insurance certificates?

Not required but strongly advised. Professional liability insurance supports contractor status and ABC element C. Documentation of insurance evidences independent business operations.

What about contractor background checks?

Cautiously. Requiring background checks can suggest employee-style control. Can be appropriate when legitimately required (licensed professions, fiduciary roles). Document business reason for check.

Can I audit my own 1099 compliance?

Yes and advised. Self-audit identifies risks before EDD does. Apply ABC test, document evidence, identify exemptions. Professional review typically valuable for larger operations.

Should contractors have their own LLC?

Supportive but not dispositive. Contractor LLC supports independent business evidence (ABC element C). Combined with other indicia, LLCs strengthen contractor classification defense.

What about 1099-K records?

Different form (payment processor reporting) but relevant if you use payment platforms. 1099-K reporting thresholds changing under current rules. Coordinate 1099-NEC and 1099-K reporting.

If you have read this far, you have a notice and you are trying to understand it before doing anything that makes it worse. That instinct is correct.
