1099 vs W-2 in Construction: The Control Test That Decides It, and What to Do If You Got It Wrong

If you direct how and when someone works, supply the tools, and keep them on indefinitely doing the core work of your business, the IRS will likely see an employee, whatever the paperwork says. That is the short answer, and it comes from the federal common-law test the IRS applies, which weighs three categories of evidence rather than one control question. If you have been paying such a worker on a 1099, two federal relief paths can reduce the cost of fixing it, and one of them still applies after an audit has started.

How the IRS Weighs the Relationship

The IRS’s independent contractor or employee guidance groups the evidence into three categories: behavioral control, financial control, and the type of relationship. Behavioral control asks whether the company controls, or has the right to control, what the worker does and how the worker does the job. No single factor decides the answer; the relationship as a whole does. The H1’s “control test” is shorthand for that whole weighing, not a single question.

Category	Points toward employee (W-2)	Points toward contractor (1099)
Behavioral control	You set hours, direct methods, train the worker	The worker decides methods and schedule
Financial control	You supply tools and equipment and pay by the hour on an ongoing basis	The worker invests in tools, can make or lose money on a job, serves other customers
Type of relationship	Indefinite engagement doing core work; benefits	Defined project under a written agreement

Take a hypothetical tile setter who has worked only for your company for two years, starts when you say, uses your saws and lifts on larger jobs, and is paid weekly. Every category points the same way. In construction the line can blur, because a long-term specialty subcontractor and a de facto employee can look alike from a distance. A subcontractor running its own crew, carrying its own insurance, bidding fixed-price scopes, and working for several general contractors sits on the contractor side. A laborer who follows your daily direction with your equipment sits on the other.

What Misclassification Costs

The cost of reclassification is the set of employer obligations that were skipped, the same costs that make up a burdened labor rate on every job:

Employer FICA. 7.65% of wages: 6.2% Social Security up to the annual wage base and 1.45% Medicare. On $60,000 of pay, that is $4,590.
Federal unemployment tax. With the maximum state credit, IRS Publication 15 puts the rate after credit at 0.6% of the first $7,000 of wages, which is $42 per worker.
Withholding that was never done. Income tax withholding and the employee share of FICA, which the employer becomes liable for on reclassification, subject to the reduced rates below.
Florida reemployment tax. Florida’s state unemployment tax on employee wages, at the employer’s assigned rate.
Workers’ compensation. In Florida construction, coverage requirements reach smaller employers than in other industries: section 440.02(20)(b)2, Florida Statutes counts private employment with “one or more employees” in the construction industry, against “four or more” for other private employers. A misclassified crew can mean an uninsured workers’ compensation exposure as well as a tax one.
Wage-and-hour liability. Employees are protected by the Fair Labor Standards Act’s minimum wage and overtime rules, which the Department of Labor enforces separately from the IRS. On federally funded construction, Davis-Bacon wage rules on federally funded work add their own wage and payroll-reporting requirements for employees.

When an employer failed to withhold because it treated an employee as a non-employee, section 3509(a) lets it pay the unpaid income tax withholding and employee FICA at reduced rates, as Rev. Rul. 2025-3 describes. Under section 3509(c), those reduced rates do not apply when the failure came from intentional disregard of the withholding requirement.

Two Relief Paths, With Different Audit Rules

Section 530 relief. Section 530 of the Revenue Act of 1978 can protect a business from federal employment tax liability for workers it treated as non-employees, if three requirements are met. Rev. Proc. 2025-10 restates them:

Reporting consistency. The business filed all required federal returns, including information returns such as Forms 1099, consistently with treating the worker as a non-employee.
Substantive consistency. The business did not treat the worker, or anyone in a substantially similar position, as an employee.
Reasonable basis. The treatment rested on reasonable reliance on judicial precedent or published rulings, a past IRS audit with no assessment for similar workers, a “long-standing recognized practice of a significant segment of the industry,” or some other reasonable basis.

Section 530 is not closed by an audit. The same revenue procedure says the IRS will give written notice of section 530’s availability “before or at the start of any employment tax audit inquiry” about worker status, and that in any such audit the IRS “will first consider whether the taxpayer has satisfied the requirements of section 530 before analyzing whether the individuals are employees.” A business already under examination should raise it.

The Voluntary Classification Settlement Program (VCSP). The VCSP is the path for a business that wants to start treating workers as employees going forward. Under the IRS’s VCSP page, the business pays 10% of the employment tax liability that would have been due on the workers’ compensation for the most recent tax year, computed at the reduced section 3509(a) rates, with no interest or penalties, and is not subject to an employment tax audit on the classification of those workers for prior years. To be eligible, the business must have consistently treated the workers as non-employees, including filing all required Forms 1099 for the previous three years; it cannot be under an IRS employment tax audit; and it cannot be under a Department of Labor or state agency audit of the classification of those workers. An audit of some other kind is not on that list. The application is Form 8952, which the IRS asks to receive at least 120 days before the date the business wants to begin treating the workers as employees.

Question	Section 530	VCSP
What it does	Relief from employment tax for workers treated as non-employees	Prospective reclassification with a reduced settlement for the past
Available during an employment tax audit	Yes; the IRS considers it first	No
Key conditions	Reporting consistency, substantive consistency, reasonable basis	Consistent treatment, Forms 1099 for three years, no employment tax or classification audit

Building a File You Can Defend

If a worker is genuinely a contractor, the defense is built before any question is asked, in how the engagement is set up and recorded:

A written agreement describing a defined scope or project.
Payment against the worker’s invoices, not a recurring payroll-style amount.
The worker’s own tools and equipment where the work allows it.
No fixed daily hours and no employee benefits.
Certificates of the worker’s own liability insurance and, where applicable, workers’ compensation coverage.
A Form 1099 filed every year, which is also the reporting-consistency requirement for section 530.

If that file cannot honestly be assembled, the documentation is giving you the answer. Fixing the classification going forward, through the VCSP if eligible, stops an exposure that grows every pay period.

When the relationship genuinely sits in a gray zone, either the business or the worker can file Form SS-8 to ask the IRS for a determination of worker status. Because the worker can file it too, the question can reach the IRS whether or not the business raises it.

The Department of Labor Test Is in Transition

The IRS test is not the only one. For minimum wage and overtime, the Department of Labor applies an “economic reality” analysis under the Fair Labor Standards Act, and in 2026 three different things are true at once:

Layer	Status	Source
The regulation on the books	The 2024 final rule, published January 10, 2024 and effective March 11, 2024, sets out a six-factor economic reality test	DOL rulemaking page
How DOL investigators apply it	Since May 1, 2025, the Wage and Hour Division no longer applies the 2024 rule's analysis in its own FLSA investigations; it follows Fact Sheet #13 (July 2008), as informed by Opinion Letter FLSA2019-6	Field Assistance Bulletin 2025-1
Private lawsuits	The 2024 rule "remains in effect for purposes of private litigation," according to the same bulletin	Field Assistance Bulletin 2025-1
What may replace it	A notice of proposed rulemaking announced February 26, 2026, with comments due April 28, 2026; still a proposal when the rulemaking page was checked on October 16, 2026	DOL rulemaking page

The sources are the DOL’s rulemaking page and Field Assistance Bulletin No. 2025-1. For a contractor, the practical consequence is that a DOL investigation and a worker’s private lawsuit can be judged against different frameworks in the same year. Confirm the standard in force for the forum you face before relying on any version of it.

Whichever version applies, the questions overlap with the IRS’s: who controls the work, and whether the worker is in business for themselves. A worker who fails the IRS analysis on every category is unlikely to be helped by the choice of test.

Paying Yourself Is a Separate Question

How an owner is paid is governed by different rules from how the crew is classified. A sole proprietor, or the owner of a single-member LLC taxed as a disregarded entity, takes draws and pays self-employment tax on the profit. An LLC’s legal form does not settle its tax treatment: the IRS treats a single-member LLC as disregarded for income tax unless it files Form 8832 and elects to be treated as a corporation. An owner of an S corporation who works in the business is paid a salary as an employee of the corporation, and the IRS expects that salary to be reasonable for the work before profits are taken as distributions. That choice belongs with a CPA, and it does not change the classification of anyone else on the payroll.

What to Do This Month

Run every recurring 1099 worker through the three categories and record the answer. For anyone who lands on the employee side, decide between documenting a section 530 position and applying to the VCSP, with a tax professional, before an employment tax audit removes the VCSP option. Then confirm Florida workers’ compensation coverage for the whole crew, because in construction the threshold starts at one employee.

This guide explains worker classification as general information, not legal or tax advice. Classification turns on the facts of each working relationship, so confirm your position with a CPA or employment attorney before acting on it.
