Arizona Small Business Health Insurance: Plans, Rules and Costs

By Michael Sprague, Licensed Health Insurance Agent · Reviewed by Heather Sprague, Licensed Health Insurance Agent

Arizona small business health insurance lets you offer coverage to your team through a small group plan, a level-funded plan or a health reimbursement arrangement that helps employees buy their own plans. Arizona small group plans are regulated by the Arizona Department of Insurance and Financial Institutions (DIFI), and since 2019 Arizona has had its own mini-COBRA law for employers with fewer than 20 workers.

This guide covers Arizona's small group rules, continuation coverage, costs and how to get started before the November 15 to December 15 enrollment window. Call 888-730-6031 for a free quote from a licensed agent.

Arizona Small Group Rules

In Arizona, a small employer for health insurance purposes has 1 to 50 eligible employees. Carriers generally need at least one W-2 employee who is not the owner or the owner's spouse, so a business owner alone usually belongs in the individual market instead.

Arizona small group plans must cover the ACA essential health benefits, and carriers cannot deny your group or price it on health history. Rates can vary only by employee age, location (Arizona has several rating areas, with Phoenix and Tucson priced differently from rural counties) and tobacco use.

Carriers usually ask that around 70% of eligible employees enroll, not counting those with other coverage, and that the employer pay at least half of the employee-only premium. Those rules are waived for applications made November 15 to December 15.

Arizona Continuation Coverage (Mini-COBRA)

Arizona's mini-COBRA law, A.R.S. 20-2330, took effect January 1, 2019. It applies to small employers that averaged at least one but fewer than 20 eligible employees in the prior calendar year, which is the group federal COBRA leaves out.

Covered employees and their dependents can generally keep the group plan for up to 18 months after a qualifying event such as job loss or reduced hours. Coverage can run longer with a Social Security disability or a second qualifying event.

The former employee pays the full premium, and the employer can add an administrative fee of up to 5%. The Arizona Department of Insurance publishes a sample notice that small employers can use to meet the notice rules.

What Small Group Health Insurance Costs in Arizona

Small Business Open Enrollment in Arizona

ICHRA in Arizona

Arizona employees with an ICHRA shop for individual plans on HealthCare.gov or directly with insurers. You can set different allowances for employee classes, such as full-time, part-time or workers in different rating areas, which helps businesses with staff in both Phoenix and rural Arizona.

How to Start a Arizona Small Group Plan

• Build an employee census with dates of birth and ZIP codes.
