If you cannot produce a certificate for a subcontractor, you get charged for their payroll at audit, and their claims can land on your policy. A process that collects certificates before the first invoice, checks four things, and diaries expiry dates prevents both. Who this is for: anyone who hires subcontractors or freelancers.
The short version
- Uninsured subcontractors are usually charged to you as payroll at your premium audit.
- Collect the certificate before the first invoice is paid, because leverage disappears after that.
- Check four things: name, dates, limits, and endorsements.
- Certificates go stale, so re-collect at each renewal and diary the dates.
- Keep them for as long as claims can arrive, which is years, not months.
Why the audit finds this
At your annual premium audit, the auditor asks for certificates for every subcontractor you paid. Anyone without one is typically treated as an uninsured subcontractor and their payments are added to your rating basis. On a general liability or workers compensation policy that produces an additional premium bill months after the work is done and long after you invoiced the client.
A process that works
- Ask up front. Before any work starts, request a certificate with your requirements attached.
- Tie it to payment. No certificate, no first payment. This is the only enforcement mechanism that reliably works.
- Check four things. Name, dates, limits, endorsements. Four checks, two minutes.
- Diary the expiry. Record the expiry date and request a renewal certificate before it passes.
- Keep the file. Store them for as long as a claim could arrive from that work.
What to require from a subcontractor
| Coverage | Typical requirement |
|---|---|
| General liability | $1M per occurrence, $2M aggregate, with you as additional insured |
| Additional insured | Ongoing and completed operations for construction work |
| Workers compensation | Statutory, or a valid filed exemption you have seen |
| Commercial auto | $1M where they drive for the job |
| Professional liability | Where they perform design or advisory work |
| Waiver of subrogation | Where your own client contract requires you to obtain one |
How long to keep them
Keep certificates and endorsements at least as long as the statute of limitations and repose for the work in your state. For construction that commonly reaches six to ten years, and for services three to six is typical. Storage is cheap and the file is what proves compliance if a claim arrives years later.

What this looks like in practice
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A small general contractor used three trade subcontractors through a busy summer and collected certificates from two of them.
What went wrong: The third was paid $84,000 with no certificate on file, and the annual premium audit added those payments to the rating basis.
What it cost: An additional premium bill of roughly $9,600 arrived four months after the projects closed and had been invoiced.
The fix: No certificate, no payment. It is one rule and it removes almost the entire exposure.
Frequently asked questions
Q: Why do I need certificates from my subcontractors?
Two reasons. At premium audit, uninsured subcontractors are usually charged to you as payroll. And if their work causes a claim, an insured subcontractor is the difference between their policy paying and yours.
Q: When should I collect them?
Before work starts, and definitely before the first invoice is paid. Once they have been paid, the leverage to obtain paperwork largely disappears.
Q: What should I check on a subcontractor certificate?
The exact legal name matches your agreement, the policy dates cover the whole engagement, the limits meet your requirements, and the additional insured and waiver endorsements are actually cited.
Q: What happens at audit if I have none?
The auditor generally treats those payments as payroll and charges premium accordingly, producing an additional bill after the work is finished and invoiced.
Q: How long should I keep certificates?
As long as claims can realistically arrive from the work, commonly six to ten years for construction and three to six for services. Storage costs almost nothing compared with the exposure.
Q: Do I need certificates from a one day freelancer?
If they are paid as a 1099 and doing work you are responsible for, yes. Auditors do not distinguish by engagement length, and neither will a claimant.
How Morrow helps with certificates of insurance

- We issue certificates the same day you ask, and usually within the hour.
- We read the contract first, so the endorsements the certificate reports actually exist on your policy.
- We push back on requirements the market will not issue, and give you language your client will accept.
- We keep a record of who was issued what, so renewals go out before anyone chases you.

One more thing. This article is general information and is not legal advice or a statement of coverage. Certificates report what a policy says, and the policy wording controls in every case. Forms and requirements vary by carrier, by state, and by contract, so have a licensed advisor review your own policy and your own contract before relying on any of it.
