Construction businesses operate in one of California’s most heavily scrutinized regulatory environments. EDD audits are common in this industry because subcontractors, short-term projects, and fluctuating labor needs create classification risk at scale. When EDD audits a construction company, it is not evaluating intent. It is evaluating facts, documentation, and whether worker relationships comply with California law.

This guide explains how EDD evaluates worker classification, how AB 5 and the ABC test apply, when the older Borello test still matters, how construction-specific rules change the analysis, and what business owners can do to build defensible subcontractor relationships before an audit begins.

Why Construction Companies Are EDD Audit Targets

Construction businesses rely on subcontractors to remain competitive and flexible. That same reliance places them squarely in EDD’s audit crosshairs. EDD focuses on construction because:

  • Labor costs are significant and recurring
  • Licensing requirements create clear compliance benchmarks
  • Misclassification directly impacts payroll tax collections
  • Prior audits often reveal systemic issues rather than isolated mistakes

Once an audit begins, EDD reviews multiple years at once. Errors compound quickly.

How EDD Evaluates Worker Classification

In California, a worker is presumed to be an employee unless the hiring entity can prove otherwise. EDD applies different legal tests depending on the relationship, but AB 5’s ABC test is the default starting point.

If an exemption applies, EDD may revert to a different analysis, including the Borello test or construction-specific statutory rules. Determining which test applies is often the most important early decision in an audit.

The ABC Test Under AB 5, Step by Step

To classify a worker as an independent contractor under AB 5, all three parts of the ABC test must be satisfied.

Part A, Freedom From Control and Direction

The worker must be free from your control both contractually and in practice.

In construction, red flags include:

  • Required daily schedules
  • Ongoing supervision beyond safety and code compliance
  • Direction on how work must be performed rather than what must be completed
  • Treating the worker as interchangeable with employees

Control is evaluated by what actually happens on the jobsite, not what the contract says.

Part B, Work Outside Your Usual Course of Business

The worker must perform work outside your usual course of business.

This is where most construction companies fail the ABC test. If your business is construction, and the worker performs core construction labor that you sell to customers, Part B is difficult to satisfy.

Hiring a separate business that provides a distinct, specialized service may help, but only if the facts support that separation.

Part C, Independently Established Trade or Business

The worker must be customarily engaged in an independently established business of the same nature.

This means the worker:

  • Operates as a business, not just for you
  • Markets services to others
  • Has financial risk and opportunity
  • Can continue operating if your relationship ends

Forms alone do not satisfy Part C. EDD looks at economic reality.

When the Borello Test Still Applies

The Borello test is a multi-factor analysis that predates AB 5. It still applies when a statutory exemption removes the relationship from the ABC test.

Borello focuses primarily on the right to control, but also evaluates:

  • Skill level required
  • Method of payment
  • Length of engagement
  • Provision of tools and equipment
  • Whether the work is part of the hiring entity’s regular business
  • The parties’ understanding of the relationship

No single factor controls the outcome. The totality of circumstances matters.

Construction Subcontractor Rules and AB 5 Exemptions

California law includes a construction subcontractor pathway that can move the analysis away from the ABC test if specific statutory requirements are met.

Key requirements typically include:

  • A written subcontract
  • Proper contractor licensing within the scope of work
  • Business licensing or tax registration where required
  • Authority to hire and fire workers
  • Responsibility for work quality, defects, and corrections
  • Evidence of an independently established business

Failure to meet even one required element can collapse the exemption.

Licensing errors are especially dangerous. Using an unlicensed subcontractor where a license is required can result in statutory employee treatment regardless of intent.

How to Validate 1099 Status the Right Way

EDD audits are documentation audits. Validation is about showing diligence and consistency, not collecting paperwork after the fact.

Effective validation includes:

  • Verifying contractor licensing and scope
  • Confirming business entity status where applicable
  • Requiring proof of insurance appropriate to the trade
  • Retaining invoices that reflect project-based billing
  • Documenting independence in scheduling, staffing, and pricing

Validation should occur at onboarding, not during an audit.

Helping Subcontractors Operate as Real Businesses

Helping subcontractors comply is not about “making them 1099s.” It is about ensuring the relationship reflects legitimate independence.

Appropriate support may include encouraging subcontractors to:

  • Register a business name if applicable
  • Obtain required trade licenses
  • Secure appropriate insurance
  • Establish separate business banking
  • Maintain a basic professional presence

What does not work:

  • Forcing workers into LLCs
  • Providing scripts or instructions to “look independent”
  • Ignoring how the relationship actually functions

If the facts resemble employment, no amount of paperwork will fix it.

Penalties for 1099 Misclassification

Misclassification exposure often includes multiple layers of liability.

California penalties

Willful misclassification can trigger significant per-worker civil penalties, in addition to back payroll taxes and interest.

EDD payroll tax assessments

EDD may assess unpaid unemployment insurance, employment training tax, state disability insurance, and personal income tax withholding, along with penalties for late filing or payment.

Federal exposure

Reclassification at the federal level can lead to employment tax assessments and additional reporting consequences.

In construction audits, penalties often multiply quickly because misclassification tends to be systemic.

Working With Your CPA Without Triggering Red Flags

There is no legitimate way to “avoid” audits. There are effective ways to reduce audit risk through accuracy and consistency.

Align with your CPA on:

  • A consistent classification policy
  • Clean separation between payroll and vendor payments
  • Accurate 1099 reporting
  • Reconciliation between job costing, disbursements, and tax filings
  • Centralized subcontractor documentation

Avoid retroactive fixes that do not match operational reality. Inconsistencies create audit trails.

What EDD Audit Defense Actually Looks Like

Audit defense is not arguing philosophy. It is applying the correct legal test, controlling scope, and presenting documentation clearly.

Effective defense typically involves:

  • Determining which classification test applies
  • Identifying exempt versus non-exempt relationships
  • Organizing subcontractor files by legal criteria
  • Addressing licensing issues early
  • Managing communications with EDD strategically

Early involvement often reduces exposure dramatically.

Frequently Asked Questions

Can a written independent contractor agreement protect me in an EDD audit?
No. Contracts matter, but EDD prioritizes how the relationship operates in reality.

If my subcontractor has an LLC, are they automatically a 1099?
No. Entity structure alone does not determine classification.

Does having a website make someone an independent contractor?
No. It may help support independence, but it is not determinative.

Can I fix misclassification issues after receiving an audit notice?
Corrective action can help limit future exposure, but it does not erase past liability.

Should I talk to EDD directly if I receive an audit letter?
You should understand your rights and risks before communicating substantively.
