If you hire subcontractors in Florida, the certificates of insurance they provide are not just paperwork. They are your financial protection against thousands of dollars in unexpected insurance audit charges — and your legal protection against liability for injuries on your job sites.
Here is everything you need to know about Florida subcontractor COI requirements and how to manage them properly.
What Is a Certificate of Insurance (COI)?
A Certificate of Insurance is a one-page document that summarizes a subcontractor's insurance coverage. It lists the types of coverage they carry, the policy limits, the carrier name, and — critically — the policy effective and expiration dates.
For Florida contractors, the most important coverages to verify on a sub's COI are:
- Workers Compensation: Must show Florida statutory limits (or an approved exemption)
- General Liability: Minimum $1M per occurrence is standard; your policy may require more
- Commercial Auto: Required if the sub uses vehicles on your job sites
Why COIs Matter for Your Insurance Audit
Here is the financial reality: in Florida, if a subcontractor you hire does not have their own workers compensation insurance, their payroll gets included in your workers comp audit. You pay their premium.
For a general contractor with $500,000 in subcontractor payments and a workers comp rate of 10%, that is $50,000 in additional audit charges — just because you did not have COIs on file.
A valid, current COI for each subcontractor is the only way to exclude their payroll from your audit. The COI must:
- Be current (not expired) for the dates the sub worked for you
- Show workers compensation coverage (or a valid Florida exemption)
- List the correct subcontracting entity name
Florida Workers Comp Exemptions
In Florida, certain business owners can exempt themselves from workers compensation requirements. A sole proprietor, partner, or officer of a corporation in the construction industry can elect an exemption — but this exemption must be properly filed with the Florida Division of Workers' Compensation.
If a subcontractor claims an exemption instead of providing a COI, you need to verify the exemption is current and valid. You can check exemption status at the Florida Division of Workers' Compensation website. An expired or invalid exemption is treated the same as no coverage — their payroll goes into your audit.
How to Collect and Track COIs
The biggest challenge for most Florida contractors is not knowing they need COIs — it is actually collecting them from every sub, every year. Here is a practical system:
- Require COIs before work begins. Make it a non-negotiable condition of your subcontract agreement. No valid COI, no work.
- Track expiration dates. Most policies expire annually. Create a calendar or spreadsheet with every sub's COI expiration date.
- Follow up 30 days before expiration. Contact subs proactively to get renewed COIs before their coverage lapses.
- Keep copies organized by policy year. Your insurance auditor will want to see COIs that cover the specific dates each sub worked for you.
What Happens If a COI Expires Mid-Project?
If a subcontractor's COI expires while they are still working for you and you do not obtain a renewal, their payroll during the lapsed period is unprotected. The auditor will include those wages in your audit — even if the sub had coverage for part of the period.
This is why proactive tracking and renewal chasing is essential. A two-week gap in coverage can cost you thousands.
