Paid Family Leave

Employers with one or more employees working in the state can offer the state-run Colorado Family and Medical Leave Insurance (FAMLI) program or choose to opt out and purchase a private plan.

Employers and employees fund the state-run program with each paying half the premium. Employers may choose to pay the full amount. Employers with less than 10 employees are not required to pay the employer share of the premium.
Employers must provide 12 weeks of paid leave and potentially more for eligible employees with a qualifying experience.

Employers can opt out by applying to the FAMLI Division of the Colorado Department of Labor and Employment.
A private plan must provide equal or greater benefits and protections than the state-run plan.
