Independent contractor classification is a high-stakes issue for businesses and workers. Misclassifying workers can lead to fines, back wages, and other penalties. States use different tests – like the ABC Test, Modified ABC Test, and Common Law Test – to determine whether a worker is an employee or contractor. While federal agencies like the IRS and Department of Labor have their own standards, state laws often impose stricter rules.
Key Takeaways:
- ABC Test: Requires proving a worker is independent across three criteria. Used in 27 states, including California and Illinois.
- Modified ABC Test: Loosens requirements, used in 6 states like Pennsylvania and Colorado.
- Common Law Test: Focuses on control and independence, used in 18 states like Texas and New York.
- Misclassification penalties range from fines to retroactive benefits and tax liabilities.
Recent changes, like the U.S. Department of Labor’s May 2025 shift to "economic realities" analysis, add complexity. Employers should stay informed of evolving rules and use tools to manage compliance effectively.

State-by-State Independent Contractor Classification Tests: ABC vs Modified ABC vs Common Law
Understanding how states classify workers is essential for compliance. The three main frameworks – ABC Test, Modified ABC Test, and Common Law Test – vary significantly in their criteria, shaping how employers determine whether someone is an employee or an independent contractor. These state-specific approaches build on the foundational tests, helping employers navigate compliance requirements tailored to their location.
States Using the ABC Test
The ABC Test requires meeting all three conditions: (A) the worker operates free from your control, (B) the work is outside your usual business activities, and (C) the worker has an independently established business.
Currently, 27 states apply the full ABC Test: Alaska, Arkansas, California, Connecticut, Delaware, Georgia, Hawaii, Illinois, Indiana, Kansas, Louisiana, Maine, Maryland, Massachusetts, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, Ohio, Oregon, Rhode Island, Tennessee, Utah, Vermont, Washington, and West Virginia.
Prong B often poses the biggest hurdle for employers. For example, if the work aligns closely with your business – like hiring a carpenter at a construction firm – the worker likely fails this prong and must be classified as an employee. A key case, Garcia v. Border Transportation Group (2018), illustrated this challenge. A California taxi driver failed Prong C because his municipal permit restricted him to working for a single taxi company, meaning he didn’t qualify as running an "independently established" business.
California has introduced some exemptions to soften the ABC Test’s impact. AB 2257 provides carve-outs for certain professions, including journalists and musicians, while Proposition 22 allows app-based drivers to remain contractors despite the test’s strict requirements.
States Using Modified ABC Tests
Some states adopt modified versions of the ABC Test, making it slightly easier to classify workers as independent contractors. These variations typically require meeting only two out of the three prongs, or they allow flexibility in which prongs must be satisfied.
Six states – Colorado, Idaho, Montana, Pennsylvania, Wisconsin, and Wyoming – use a Modified ABC Test requiring only Prongs A and C. This eliminates the need to prove the work falls outside your usual business operations.
Oklahoma and Virginia apply a different modification, allowing workers to qualify if they meet either (A and B) or (A and C). Virginia enforces these rules strictly, with HB 1407 empowering the Department of Taxation to issue civil penalties of up to $1,000 per employee for first-time misclassification and up to $5,000 for repeat offenses.
States Using the Common Law Test
For states not using the ABC framework, the Common Law Test offers a more flexible method. This approach examines factors like control over work methods, financial independence, and the overall nature of the relationship.
Eighteen states and Washington, D.C. primarily rely on the Common Law Test: Alabama, Arizona, Florida, Iowa, Kentucky, Michigan, Minnesota, Mississippi, Missouri, New York, North Carolina, North Dakota, South Carolina, South Dakota, Texas, and the District of Columbia.
Unlike the ABC Test, the Common Law Test doesn’t start with a presumption of employee status. A notable example is the 2016 case Great N. Constr., Inc. v. Dept. of Labor, where a Vermont construction company demonstrated that a historic reconstruction specialist was an independent contractor. The worker set his own schedule, operated independently, managed material costs using his own credit card, and had previously declined a full-time employment offer.
While the Common Law Test is more flexible, it’s important to note that a worker classified as an independent contractor under federal Common Law may still be considered an employee under a state’s ABC Test, especially for benefits like unemployment insurance.
State Classification Laws Comparison Table
Here’s a detailed look at how different states approach worker classification, including their primary tests, recent legislative updates, and compliance highlights.
| State | Primary Test Used | Recent Law Changes / Key Compliance Notes |
|---|---|---|

This table highlights the varied classification rules across states, emphasizing the importance of adapting compliance strategies to meet regional requirements.
Worker misclassification rates hover between 10% and 20%, underscoring the need for accurate classification practices.
As of May 2025, the U.S. Department of Labor has shifted back to a "totality of the circumstances" approach, moving away from the stricter 2024 rules. According to Field Assistance Bulletin 2025-1, the DOL is "reconsidering the 2024 Rule, including whether to rescind the regulation" and will no longer rely on its analysis when determining worker status. This change adds another layer of complexity to aligning state and federal compliance efforts.
How to Stay Compliant in Construction and Energy
Employers in the construction and energy sectors face tough challenges when it comes to managing worker classification, especially across state lines. Misclassifying workers can lead to hefty financial penalties and other risks. The solution lies in combining smart technology with consistent practices to navigate these complexities effectively. Using compliance-focused technology can make meeting these challenges far easier.
Using Technology to Manage Compliance
ABLEMKR simplifies compliance by integrating classification checks directly into the hiring process. Instead of manually reviewing state-specific rules, the platform tracks which of the 33 states apply the ABC test and which 18 states use the Common Law test. It flags potential misclassification issues before onboarding begins, helping employers avoid costly mistakes. This is particularly critical for construction firms, as roles like welders or carpenters often fail "Prong B" of the ABC test, which requires work to fall outside the company’s usual business activities.
The platform also helps employers maintain operational separation, which is essential under "Prong A." ABLEMKR’s mobile-first system lets contractors manage their schedules, submit invoices, and track certifications independently, creating records that demonstrate limited employer control – a key factor during audits. Additionally, its payroll workflows and real-time worker status features allow businesses to confirm independent contractor credentials, such as LLC registrations and insurance coverage, while ensuring contract language avoids terms that suggest an employer-employee relationship. This level of integration makes managing compliance across multiple states more efficient.
Best Practices for Multi-State Operations
Maintaining thorough records is critical. Keep detailed documentation of contractor relationships, including who provides tools, how payment terms are negotiated, and the duration of projects. These records should be retained for at least three years. For projects spanning multiple states, use a master contract template that includes customized state-specific clauses, such as "governing law" and "dispute venue" provisions.
Regular audits of hiring practices are also essential. State laws can change frequently, and the U.S. Department of Labor now uses a "totality of the circumstances" approach to evaluate worker classification. If you identify a misclassification issue internally, the IRS Voluntary Classification Settlement Program (VCSP) offers a way to reclassify workers with reduced penalties. For particularly tricky cases, like determining the status of a specialized energy consultant working in multiple states, filing IRS Form SS-8 can provide an official determination.
Conclusion
State-specific independent contractor tests are both legal requirements and financial safeguards. Estimates suggest that about 10% to 20% of workers are misclassified. In California, for example, penalties for intentional misclassification can range from $5,000 to $25,000 per worker. For construction and energy companies operating across multiple states, these risks multiply. A worker classified correctly under federal IRS rules might still be considered an employee under a state’s stricter ABC test.
The consequences go beyond fines. Misclassified workers in construction and energy industries often lose out on significant annual earnings compared to properly classified employees. Employers, on the other hand, may face retroactive liabilities, such as unpaid overtime and workers’ compensation gaps. In some states, like Illinois, repeat violations could even result in losing a business license. With over 30 states now enforcing some version of the ABC test – more stringent than the traditional Common Law standard – staying compliant has become increasingly challenging. Given these stakes, leveraging technology to navigate compliance is no longer optional.
Advanced compliance tools offer a practical solution to this growing complexity. For instance, ABLEMKR’s platform integrates compliance tracking right into workforce management workflows. It flags potential misclassification issues before onboarding begins, tracks which states use the ABC test versus the Common Law test, and securely stores digital records for the required three-year minimum. The platform also verifies contractor credentials, easing the burden of managing compliance across state lines. For construction and energy firms juggling multi-state operations, such automation reduces manual tracking efforts while maintaining a clear audit trail.
The regulatory environment remains in flux. Between 2024 and May 2025, the U.S. Department of Labor shifted its enforcement approach twice, reverting from a Final Rule to a "pre-2024" economic realities test. Meanwhile, states like New York now require written contracts for freelance work exceeding $800 – a common threshold in construction and energy consulting. As regulations continue to evolve, systems capable of adapting automatically ensure ongoing compliance. This highlights the importance of tailored, state-specific compliance strategies for construction and energy companies navigating these challenges.
FAQs
Which state’s test applies if my contractor works in multiple states?
If a contractor operates across multiple states, the rules for determining their classification depend on the laws of the state where the work is carried out. States use different methods, like the ABC test or the common law control test, to evaluate whether someone qualifies as an independent contractor. It’s crucial for employers to carefully examine the specific guidelines in each state to stay compliant with local regulations.
What’s the fastest way to tell if a role will fail Prong B of the ABC test?
To figure out if a role might fail Prong B of the ABC test, ask this: Is the work being done part of the company’s regular business activities? If the answer is yes, then the role is likely considered an employee position rather than that of an independent contractor. This part of the test plays a major role in determining the correct classification.
What should I do if I discover we misclassified a worker?
If you find out that a worker has been misclassified, it’s worth considering self-reporting. Doing so can help lower the risk of heavy penalties. Misclassifying workers can result in hefty back taxes, fines, and penalties, which often fall between $5,000 and $15,000 per worker for first-time offenses. One option to explore is the IRS Voluntary Classification Settlement Program, which offers a way to potentially reduce these penalties. Make sure to carefully review both state and federal laws to handle the legal and financial consequences properly.
