Subcontractor Insurance & Risk Management
Does a W-9 Make Someone a Subcontractor?
You have someone’s W-9, you plan to pay them as an independent contractor, and they are ready to start work. From an insurance and risk-management standpoint, that is only one part of the picture. The general contractor still needs to think about insurance verification, documentation, and risk transfer before the work begins.
The Short Answer
A W-9 does not replace the insurance and risk-management steps involved in using a subcontractor. A general contractor may also need to verify the subcontractor’s insurance, maintain certificates and applicable endorsements, use a written subcontractor agreement, and confirm that required coverage remains active.
What Does a W-9 Actually Tell a General Contractor?
What information is on a W-9?
A W-9 provides identifying and taxpayer information used for tax reporting purposes. It can help a business document information such as a name, business name when applicable, address, and taxpayer identification number.
What a W-9 does not tell you about insurance
A W-9 does not show whether the subcontractor currently carries the insurance that may be relevant to the work or the project. Depending on the situation, that can include:
- General liability
- Workers’ compensation
- Commercial auto
- Excess liability when required
It also does not show whether those policies meet the insurance requirements in your contract. Having someone’s tax information and verifying their insurance are two separate tasks.
Why This Matters to General Contractors
General contractors often bring subcontractors onto projects because the job requires multiple trades and specialties. The problems tend to appear later when the documentation behind that relationship has not kept pace with the work.
The issue may surface when:
- An insurance audit takes place.
- A subcontractor’s employee is injured.
- The subcontractor causes property damage.
- A required policy has expired.
- You need to demonstrate compliance with your own contract requirements.
A W-9 Is Not a Certificate of Insurance
A certificate of insurance serves a different purpose. It can provide evidence of the insurance policies a subcontractor reports carrying and show details such as policy types, policy dates, and limits. When a project requires specific endorsements or wording, those requirements need to be reviewed separately as well.
Rich Tygett points out an important practical problem: a subcontractor may have general liability, workers’ compensation, commercial auto, and excess policies that renew on different dates. Collecting one document once a year can leave a gap if another important policy expires or is not renewed.

A certificate does not create coverage that the policy does not contain.
The underlying policy still matters. If the contract requires a particular limit, endorsement, or type of coverage, the policy and supporting documentation need to be reviewed against that requirement.
What Happens If the Subcontractor Does Not Have the Right Insurance?
Insurance audit problems
One of the most common problems may not begin with a claim. It can appear during an insurance audit. When a contractor cannot provide the insurance documentation expected for a subcontractor, the insurer may assess additional premium or otherwise treat the exposure differently based on the policy and audit rules involved.
A subcontractor’s employee gets hurt
Workers’ compensation is another reason documentation matters. If a subcontractor does not have the required workers’ compensation coverage, the general contractor can face a significant exposure depending on the facts, the policy, and applicable state rules.

The subcontractor causes damage
If damage arises from a subcontractor’s operations, you want the subcontractor’s insurance and contractual responsibilities addressed before work starts. Waiting until after a loss is the wrong time to find out that coverage was missing, expired, or subject to a condition you did not know about.
The Three Pillars of Using Subcontractors Properly
For general contractors, a better system is to treat subcontractor management as an ongoing process built around three areas: Verification, Documentation, and Risk Transfer.
1. Verification
Determine which insurance needs to be verified before the subcontractor starts. Depending on the project and trade, that may include general liability, workers’ compensation, commercial auto, and excess liability.
Do not stop at “Do you have insurance?” Verify the relevant coverage and track renewal and expiration dates.
2. Documentation
Keep an organized subcontractor file that can include the signed agreement, certificates of insurance, required endorsements, coverage records, and renewal information. Rich refers to organized subcontractor records as “T files.”
The goal is not paperwork for its own sake. It is being able to show what was required, what was provided, and whether it was current.
3. Risk Transfer
A written subcontractor agreement and corresponding insurance requirements can help establish responsibilities between the general contractor and subcontractor. Depending on the job, that may include required limits, additional insured status, indemnification provisions, and other contract-specific obligations.
Contract terms can involve legal issues, so contract language should be reviewed by qualified legal counsel when appropriate.
What Should a General Contractor Collect Before a Subcontractor Starts Work?
Exact requirements vary by project, policy, trade, contract, and state. A practical subcontractor file may include:
- Completed W-9 where appropriate
- Signed subcontractor agreement
- Current certificate of insurance
- Evidence of general liability coverage
- Workers’ compensation documentation where applicable
- Commercial auto documentation where applicable
- Excess liability documentation when required
- Required endorsements
- Additional insured documentation when required
- Policy expiration and renewal dates
- Any project-specific insurance requirements
The W-9 can be one document in the file. It should not be mistaken for the entire subcontractor risk-management process.
What If You Have Already Been Using Subcontractors With Only W-9s?
Start with the subcontractors who are working now and the jobs coming up next. Then work through the documentation in a practical order:
- Identify the subcontractors you are currently using.
- Review the insurance documentation you already have.
- Check expiration and renewal dates.
- Review your own policy for subcontractor-related conditions or exclusions.
- Compare the documentation against the job’s insurance requirements.
- Address gaps before the next subcontractor starts work.
If you are preparing for a new job, the contract may also impose insurance requirements on you as the prime contractor and on the subcontractors you bring to the site. Reviewing those requirements before the work begins can help prevent surprises later.
Review construction job insurance requirements before you bid or start work.
Your Own General Liability Policy Matters Too
Collecting documentation from subcontractors is only one side of the process. Your own general liability policy can contain conditions, exclusions, or endorsements that affect subcontracted work. A policy that looks straightforward on the declarations page may operate differently once those provisions are considered.
Questions worth reviewing include:
- Does the policy contain conditions relating to subcontracted work?
- Are there subcontractor insurance requirements?
- Are there exclusions that affect work performed by subcontractors?
- Does the project contract require coverage or endorsements beyond your current program?

Frequently Asked Questions
Does a W-9 prove someone has insurance?
No. A W-9 provides taxpayer information. Insurance needs to be verified separately through the appropriate policy documentation, certificates, and endorsements required for the project.
Is a 1099 worker automatically a subcontractor?
A tax form or payment method by itself should not be treated as a complete worker-classification determination. Classification can depend on the facts and applicable law. From an insurance standpoint, the important step is to verify the coverage, documentation, and contractual requirements that apply to the relationship.
Should I get a certificate of insurance from every subcontractor?
A general contractor should determine the insurance documentation required by the policy, project contract, subcontractor agreement, trade, and applicable rules. A current certificate is commonly part of that process, but it may not be the only document required.
What insurance should I verify from a subcontractor?
Depending on the work and the job requirements, the relevant coverage may include general liability, workers’ compensation, commercial auto, and excess liability. The correct list depends on the specific subcontractor and project.
How often should I update subcontractor certificates?
Track the expiration dates of the policies you are required to verify. Different policies can renew on different dates, so relying on one annual collection date may leave another policy expired or missing.
What happens if my subcontractor does not have workers’ compensation?
The exposure depends on the facts, the subcontractor relationship, the applicable policy, and state requirements. Missing workers’ compensation documentation can create significant problems for a general contractor, particularly when an injury occurs or an audit is performed.
Can my general liability policy cover an uninsured subcontractor?
Do not assume it will. General liability policies can contain subcontractor-related conditions, exclusions, or endorsements. Your actual policy should be reviewed before relying on it for work performed by an uninsured subcontractor.
What should I keep in a subcontractor file?
Depending on the project, a subcontractor file may include the W-9, signed subcontractor agreement, certificates of insurance, required endorsements, renewal information, and documentation showing the insurance requirements that applied to the subcontractor’s work.
