Frequently asked — Connecticut workers' comp
Do I need workers' comp if I have only one employee in Connecticut?
Yes — Connecticut requires workers' comp coverage starting with one employee.
Are 1099 contractors covered under my Connecticut workers' comp policy?
Generally no — true independent contractors are not employees and not covered. However, Connecticut (like most states) applies an "ABC test" or similar to determine if a 1099 worker is actually a misclassified employee. If they're misclassified, you may owe back premium and penalties. Many general contractors require their 1099 subs to carry their own workers' comp.
Can I get pay-as-you-go workers' comp in Connecticut?
Yes — most major carriers offer pay-as-you-go workers' comp in Connecticut, with premium based on actual payroll each pay period instead of a large upfront deposit.
