Quick answer: Usually, yes, one way or another. A 1099 does not settle anything: if the worker is really an employee under your state's test, you must cover them on your own policy. If they are a genuine subcontractor, they should carry their own workers' comp, and in most of Aiden Risk's 16 states, if they don't, the law can make you, the hiring contractor, liable for their injured workers. Your carrier will also add what you paid an uninsured sub to your payroll at audit and charge premium on it. The practical answer is to collect proof of each sub's workers' comp (or a valid state exemption) before they start, and to price in coverage when they can't show it.
This is one of the most expensive misunderstandings in construction. Owners assume a 1099 moves the injury risk to the worker. In practice it often moves it back up the contract chain, to whoever had insurance. Rules change and turn on facts, so confirm anything specific to your jobs with your broker, carrier or counsel.
Two questions, not one
"Do I need workers' comp for subcontractors?" is really two different questions. Mixing them up is how good companies end up with a large audit bill or an uncovered claim.
Question 1: Is this 1099 worker actually your employee?
Every state has its own test for whether someone is an employee or an independent contractor, and the IRS form you file does not control it. Some states use a common-law right-to-control test. Others use an ABC test, which presumes the worker is an employee unless the hiring company proves the worker is free from control, is doing work outside the company's usual business (or outside its places of business, in some versions), and runs an independently established business. Several states layer a construction-specific law on top.
New York's Construction Industry Fair Play Act, in effect since October 26, 2010, presumes construction workers are employees unless they pass a three-part test or a 12-part "separate business entity" test, and it applies to workers' comp determinations. Pennsylvania's Construction Workplace Misclassification Act requires a written contract, freedom from control and an independently established business before a construction worker counts as an independent contractor for workers' comp. California's AB5 ABC test applies broadly, but a construction subcontract meeting every condition in Labor Code 2781 (written subcontract, CSLB license covering the work, separate business location, and more) is judged under the older Borello test.
Watch which law a test belongs to. Massachusetts' well-known ABC test sits in its wage law (c.149, s.148B), not in its workers' comp statute (c.152). New Jersey's ABC test is written into its unemployment law, and new state regulations effective October 1, 2026 apply it to the unemployment, wage and hour, and wage payment laws, not workers' comp. In both states, ask the workers' comp agency or counsel which test applies to a comp claim.
If the worker fails your state's test, they are your employee for workers' comp. Their pay belongs on your policy at the right class code, and an injury is your claim.
Question 2: Even if they are a real business, are you on the hook for their workers?
Now assume the sub is a genuine independent business with its own crew. Most states still protect that crew through a statutory employer rule, often called "up-the-ladder" liability. If the sub has no workers' comp, the law treats the contractor above it as the employer for benefit purposes. Florida's statute is typical: when a contractor sublets work, the contractor is liable for compensation to the sub's employees unless the sub has secured coverage.
Most of these statutes give the upper-tier contractor a right to recover what it paid from the uninsured sub. That right is only as good as the sub's balance sheet, which is usually the reason they were uninsured in the first place.
State-by-state rules in Aiden Risk's 16 states
This table summarizes the core rule in each state where Aiden Risk is licensed. It is a starting point, not a substitute for the statute or the state agency. Where we could not verify a rule from an authoritative source, the cell says so.
| State | Liable for an uninsured sub's employees? | Worker classification test | Notable construction rule |
|---|---|---|---|
| Arizona | Yes, if you retain supervision or control and the work is part of your business (A.R.S. 23-902). | Independent contractor if free of the business's rule or control and hired for a definite job (A.R.S. 23-902). | Check with the Industrial Commission of Arizona. |
| California | Check with the state agency. Unlicensed subs doing licensed work are presumed employees (Lab. Code 2750.5). | ABC test (AB5); qualifying construction subs judged under Borello (Lab. Code 2781). | Licensed work requires a valid CSLB license to be treated as an independent contractor. |
| Colorado | Yes. Contracting out your work makes you a statutory employer (C.R.S. 8-41-401). | Employee unless free from control and customarily in an independent business (C.R.S. 8-40-202). | A signed agreement with required disclosures creates a rebuttable presumption of independence. |
| Delaware | If you don't collect proof of coverage or exemption, you are deemed to insure claims (19 Del. C. 2311). | Workplace Fraud Act presumes construction workers are employees. | Keep each sub's certificate or officer exemption notice for 3 years. |
| Florida | Yes, unless the sub secured its own coverage (F.S. 440.10). | Independent contractors in construction are employees under Florida workers' comp law. | Exemptions only for corporate or LLC officers owning 10% or more, max three per company. |
| Georgia | Yes, for injuries on premises where the contractor is executing the work (O.C.G.A. 34-9-8). | Right-to-control test: time, manner and method of the work. | Claim goes first against the immediate employer; paying contractor can recover from it. |
| Illinois | Yes, unless the sub insured or guaranteed its liability (820 ILCS 305/1(a)(3)). | Employee Classification Act presumes construction workers are employees. | Misclassification findings are referred to the Workers' Compensation Commission. |
| Maryland | Yes, principal contractor pays as if it employed the worker (Lab. & Empl. 9-508). | Workplace Fraud Act presumes construction and landscaping workers are employees (ABC test). | Principal contractor is entitled to indemnity from the sub's direct employer. |
| Massachusetts | Yes. Your insurer pays the uninsured sub's employees and may recover from the sub (c.152 s.18). | Check with the Department of Industrial Accidents. The c.149 s.148B ABC test is a wage law. | Check with the state agency. |
| New Jersey | Yes, if the sub fails to carry workers' comp (N.J.S.A. 34:15-79). | ABC test for wage and UI laws; for workers' comp, check with the state agency. | NJDOL ABC test regulations for wage and UI laws take effect October 1, 2026. |
| New York | Yes, secondary to the sub; you can recover from the sub (WCL 56). | Fair Play Act presumes construction workers are employees: ABC or 12-part business test. | Willful misclassification: civil penalties up to $2,500 per worker for a first violation. |
| Ohio | Check with the Ohio Bureau of Workers' Compensation. | Construction: employee if 10 of 20 statutory factors apply (R.C. 4123.01). | Monopolistic state: private carriers cannot sell workers' comp; coverage comes through Ohio BWC. |
| Pennsylvania | Yes, secondary liability for an uninsured sub's employees (77 P.S. 461, 462). | Act 72: written contract, freedom from control, independent business required in construction. | Statutory employers also get tort immunity under a five-part test. |
| Texas | Limited. Coverage is optional; a covered GC is employer of a sub without employees (Lab. Code 406.123). | Statutory independent contractor definition (Lab. Code 406.121, 406.122). | Public building or construction contracts require coverage certificates from every sub (406.096). |
| Virginia | Yes. Owners and contractors are liable as if they employed the worker (Va. Code 65.2-302). | Common-law right-to-control test; worker must prove employment. | Liability extends down the chain to lower-tier subcontractors' workers. |
| Washington | You can owe a sub's unpaid premiums unless six conditions are met (RCW 51.12.070). | L&I flags control signs: assigning tasks, training, paying wages, setting hours. | Monopolistic state: verify the sub's L&I account and Certificate of Coverage. |
Outside Texas, "they're a sub, so it's their problem" is rarely true for an uninsured sub's crew. And the construction laws in New York, Illinois, Delaware and Maryland presume the worker is an employee, putting the burden of proof on you.
Ohio and Washington are monopolistic states. You buy workers' comp from the state fund, not a private carrier, and the state policy does not include employers liability coverage, which is usually added as "stop gap" coverage elsewhere in your program. Texas is the opposite extreme: most private employers may choose not to carry workers' comp at all, but those non-subscribers must report that status to the state, and public building and construction contracts require coverage certificates from the contractor and every sub on the project.
The audit bill: how uninsured subs land on your payroll
Even if no one gets hurt, uninsured subs cost you money at the annual premium audit. Workers' comp premium is a rate per $100 of payroll by class code, estimated at the start of the policy and trued up at the end. Under NCCI's Basic Manual Rule 2-H, the subcontractor rule used where NCCI's manual applies, a contractor avoids premium on a sub only by showing evidence that the sub had its own workers' comp in force (or, where the state offers one, a certificate of exemption).
Without that evidence, the auditor treats the sub's labor as yours. If the sub's payroll records are available, that payroll is used. If not, the rule falls back to tables based on the documentation you have, and with nothing to separate labor from materials, the full subcontract price can become premium-bearing payroll, charged at the class code for the work performed. Nationwide's premium audit guidance says the same thing in plain terms: with no evidence of the sub's insurance, its payroll may be added to your premium base, and most state workers' comp laws can hold you responsible for injuries to an uninsured sub's employee. AmTrust's loss control guidance adds that an uninsured sub can raise your workers' comp premiums for years, because your policy may be used to pay the claim.
A 2022 Alaska Division of Insurance decision shows how strictly this is applied. A general contractor produced a certificate of insurance and a signed subcontract for a one-person sub who had no workers' comp, and argued the sub was a true independent contractor. With no payroll records, the carrier included the full subcontract price, and the state upheld the audit under Rule 2-H without deciding the classification argument.
To see the scale, take an illustrative $200,000 framing subcontract with no workers' comp certificate and no payroll records. If the applicable class rate on your policy were $8 per $100 of payroll, the audit could add $16,000 of premium for that one sub, before any experience mod is applied. Rates vary widely by state and class, so ask your broker to run your actual numbers. For more on how audits and mods work at scale, see our workers' comp guide for mid-market companies.
What to collect from every subcontractor
Your defense against both statutory employer liability and audit charges is paperwork, collected before the sub mobilizes and kept current until they finish.
- Certificate of insurance showing workers' comp: policy number, carrier, the state where the work is performed, and effective dates that cover the whole period of the work. Request general liability on the same certificate, with the additional insured and waiver wording your contract requires. Our certificate of insurance guide explains each box.
- State exemption certificates where they exist: in Florida, a corporate or LLC officer can hold a construction exemption, and the state tells contractors to keep a copy. Delaware requires you to keep a sub's officer exemption notice or certificate for 3 years.
- A written subcontract: scope, insurance requirements with minimum limits, an obligation to keep coverage in force and notify you of cancellation, indemnity, and your right to withhold payment for lapses. Written contracts also help on classification in several states.
- W-9 and business identifiers: legal name, tax ID, contractor license or registration number. Washington L&I tells general contractors to keep each sub's UBI number and registration details.
- Verification against the state, not just the certificate: several states publish coverage lookups. Washington L&I tells GCs to check a sub's Certificate of Coverage each year and offers tracking alerts, and Florida publishes proof of coverage and valid exemptions online.
- Renewal tracking: a certificate proves coverage on the day it was issued. Diary each expiration date and get a renewal certificate before you pay the next invoice. AmTrust's loss control guidance suggests a reminder at least one week before each sub's workers' comp and general liability policies expire.
Read the certificate, don't just file it
Check that the named insured matches the company on your subcontract, that the policy lists the state of your job, and that the dates span the work. Out-of-state subs are a common gap: Florida requires out-of-state construction employers working there to carry a Florida policy or list Florida in Section 3.A of their home-state policy, apart from short temporary work.
Be especially careful with one-person shops that show a workers' comp certificate. Some small subs buy a minimum-premium policy that reports no payroll, sometimes called a "ghost policy" in the trade, often with the owner excluded from coverage. The certificate looks normal, but if the owner is excluded, the person actually doing the work may have no benefits if hurt, and if the sub quietly brings helpers, you are relying on a policy priced as though they don't exist. Ask who is on the crew and whether the owner is included or excluded before you accept it.
Sole proprietors and owner-operators
Many states let sole proprietors, partners or corporate officers leave themselves off workers' comp. That is a choice about their own coverage, not a reason to hire them without proof.
Three problems come up. First, the exemption covers only the owner; Florida is explicit that exemption holders cannot collect workers' comp benefits, and it says nothing about the people they hire. Second, the moment a solo sub brings a helper, that helper is an employee who needs coverage, and in a statutory employer state that helper's injury can come up the ladder to you. Third, the exemption does not answer the classification question: a "sole proprietor" who works only for you, on your schedule, with your tools, may simply be your employee under your state's test.
Florida is stricter for construction: its Division of Workers' Compensation treats sole proprietors and independent contractors in construction as employees, and only qualifying corporate or LLC officers can be exempt.
A practical decision flow for every 1099 worker and sub
- Apply your state's test. Would this worker be an employee under the test in the table above, including any construction-specific law? If yes, put them on your payroll and your workers' comp policy at the right class code. A 1099 does not change the answer.
- If they are a genuine sub, ask for proof. Do they have their own workers' comp policy covering the state and dates of your job, or a valid state exemption for the owners, with no employees helping them?
- Verify it. Check the certificate against the state's coverage lookup where one exists, confirm the owner's status, and diary the expiration date.
- If they cannot show coverage, expect two costs. Assume the sub's crew is your exposure for injuries in most of these states, and assume the full subcontract price may be added to your payroll at audit.
- Choose a path. Require the sub to buy coverage before mobilizing; or, where your carrier and state allow it, cover them under your policy and price the premium into the subcontract (Texas Labor Code 406.123 expressly allows a written agreement and premium deduction); or don't use them.
Workers' comp is only half of the subcontract insurance picture. Your general liability policy also needs to hold up when a sub's worker sues you, which is where contractual liability and the additional insured problem come in. Our contractor insurance guide covers how those pieces fit together.
How Aiden Risk Solves Each of These Problems
Most contractors handle these issues in pieces: a carrier for the policy, an office manager for certificates, a lawyer for the subcontract, and a surprise at audit. Aiden Risk is an AI-native independent commercial insurance broker that pairs an AI risk engine built for commercial insurance with licensed brokers, so one partner covers the whole subcontractor problem across the 16 states in the table above.
| The problem | How Aiden Risk solves it |
|---|---|
| 1099 workers who may really be employees | A licensed broker reviews how you use 1099 workers and helps you put anyone who belongs on your policy at the right class code with a realistic payroll estimate, so the cost sits in your premium instead of appearing at audit. Where the employee test itself is close, the broker will point you to counsel. |
| Being treated as the employer of an uninsured sub's crew | A licensed broker runs a coverage gap analysis before binding to confirm your own workers' comp and employers liability are in place in every state you work in, so you are not uninsured if the law treats you as the statutory employer. |
| Different rules in each of the 16 states, and jobs that cross state lines | Aiden Risk is licensed in all 16 states covered here. The AI monitors your risk year-round and flags changes such as work in a new state, and a licensed broker acts on every flag, including getting that state onto your policy. |
| Monopolistic states (Ohio and Washington) | A licensed broker reviews how your state fund coverage fits with the rest of your program and helps arrange stop gap employers liability coverage, which the state policy does not include. |
| Surprise audit charges for uninsured subs | A licensed broker reviews your audit worksheets with you before they go back to the carrier, checks that sub certificates line up with each payment, and corrects your payroll estimate mid-term when your use of uninsured subs changes. |
| Sole proprietors and owner-operators who bring helpers | A licensed broker reviews owner-operator subs with you, including whether the owner is exempt and whether helpers are covered, and advises whether to require coverage or, where your carrier and state allow it, cover them and price it into the subcontract. |
| Exemption certificates that cover less than they appear to | A licensed broker reviews state exemption documents with you, such as Florida construction exemptions and Delaware exemption notices, and flags that they cover only the named owners, not anyone they hire. |
| Ghost policies and owner-excluded certificates | A licensed broker reviews questionable workers' comp certificates with you, asking who is on the crew and whether the owner is included or excluded, before you accept the sub. |
| Certificates that lapse in the middle of a job | A licensed broker advises on subcontract clauses that require continuous coverage and notice of cancellation, and you can grade each renewal certificate in the free COI checker from your answers about it before paying the next invoice. |
| Weak or missing insurance clauses in your subcontracts | A licensed broker reviews the insurance requirements you hand to subs, including limits, additional insured and waiver of subrogation, and the free COI checker grades a sub's certificate against those requirements from your answers, flagging gaps. |
Behind all of this, Aiden Risk places contractor workers' comp across 100+ carriers, including admitted and surplus lines carriers.

You can see our state licenses on the licenses page and the full contractor insurance program.
Key Takeaways
- A 1099 does not decide workers' comp status. Your state's employee test does, and several states presume construction workers are employees.
- In most of Aiden Risk's 16 states, a contractor can be liable for an uninsured sub's injured employees under a statutory employer rule, though Ohio and Washington run monopolistic state funds and Texas makes coverage optional for most private employers.
- At audit, payments to subs without proof of workers' comp are usually added to your payroll, and with no payroll records the full subcontract price can be used.
- Collect a workers' comp certificate (or valid state exemption), a written subcontract and a W-9 before work starts, verify with the state where you can, and track renewals.
- Owner exemptions protect no one but the owner's premium. Helpers still need coverage, and a misclassified "sole proprietor" may be your employee.
- Aiden Risk handles the whole problem in one place: a licensed broker reviews your classifications, certificates, exemptions, subcontract insurance clauses and audit worksheets, while the AI monitors your risk year-round and flags changes for the broker to act on.
FAQs
Do I need workers' comp for 1099 subcontractors?
If the 1099 worker is really an employee under your state's test, yes, they belong on your policy. If they are a genuine subcontractor, they should carry their own coverage, and you should collect proof. If they don't, most states can hold you liable for their employees' injuries and your carrier will typically charge premium on what you paid them.
Is a general contractor liable if a subcontractor doesn't have workers' comp?
In most states, yes. Statutory employer laws in states such as Florida, New York, Pennsylvania, Virginia and Maryland make the upper-tier contractor liable for benefits to an uninsured sub's employees, usually with a right to recover from the sub. Texas is a notable exception because workers' comp is optional for most private employers there.
What is a statutory employer?
A statutory employer is a business the workers' comp law treats as the employer of someone it does not directly employ, typically a contractor whose subcontractor's worker is hurt on the job. The rule makes sure injured workers get benefits when their direct employer is uninsured. In some states, such as Pennsylvania, statutory employer status also gives the contractor immunity from a negligence lawsuit by that worker.
Can a 1099 worker be considered an employee for workers' comp?
Yes. States decide employee status using their own tests, such as right-to-control tests or ABC tests, regardless of how the worker is paid or what tax form they receive. Construction-specific laws in New York, Illinois, Delaware and Maryland presume construction workers are employees unless the hiring company proves otherwise.
Do sole proprietors need workers' comp?
Many states let sole proprietors exclude themselves, but any employees they hire must be covered. Florida is stricter in construction, where only qualifying corporate or LLC officers can be exempt. For the contractor hiring them, an owner exemption does not cover the owner's helpers or answer whether the owner is really your employee.
What happens at audit if a subcontractor has no insurance?
Under NCCI's Basic Manual subcontractor rule, and similar carrier audit practice, the auditor adds the sub's payroll to yours if you cannot show the sub had workers' comp in force. If the sub's payroll records are not available, the full subcontract price for the work can be treated as payroll at the class rate for the work performed. Collecting certificates before work starts is the main way to avoid the charge.
What is a workers' comp exemption certificate?
It is a state-issued document showing that a business owner or officer has elected not to be covered by workers' comp, available only in some states and on specific terms. In Florida construction, corporate or LLC officers owning at least 10% can apply, with a maximum of three per company, and contractors are told to keep a copy. An exemption covers only the named owners, not any employees.
