Quick answer
Open Enrollment is now open on HealthCare.gov. To enroll in Phoenix: gather income and household details, estimate your 2027 income, list your doctors and prescriptions, compare plans across insurers and metal levels, then apply and choose a plan by December 15 for January 1 coverage. Pay your first premium on time, or the plan will not start.
Enrolling is easier when you have everything in front of you before you start. This checklist is built for Phoenix-area households using HealthCare.gov, Arizona's Marketplace, and it works whether you enroll yourself or with a broker.
Who this checklist is for
- First-time buyers of individual or family coverage in the Valley
- Current Marketplace members who plan to review and switch
- Self-employed people and early retirees estimating variable income
Step 1: Gather your documents
| What you need | Why |
|---|---|
| Names, birth dates and Social Security numbers for everyone applying | Identity and eligibility checks |
| Home address and mailing address | Plans and prices are set by ZIP code and county |
| Recent pay stubs, a profit-and-loss estimate or last tax return | To estimate 2027 household income |
| Information about any job-based coverage offered to your household | An affordable employer offer can affect tax credit eligibility |
| Current plan details, if any | To compare costs and networks |
| List of doctors, hospitals and prescriptions | To check networks and drug lists |
Step 2: Estimate 2027 income carefully
HealthCare.gov bases savings on your expected income for the coverage year, not last year. If you are self-employed, use expected net self-employment income. Estimate too low and you may repay part of your tax credit at tax time. Estimate too high and you pay more each month than you need to. You can update your estimate during the year if things change.
Step 3: Compare plans the right way
- Total yearly cost: premium times 12, plus the deductible and likely copays
- Out-of-pocket maximum: your worst-case year
- Network: your doctors and hospital, checked plan by plan
- Drug coverage: covered or not, and which tier
- Metal level: if you qualify for cost-sharing reductions, start with Silver
Step 4: Apply, choose and pay
Complete the application, review your eligibility results, pick a plan, and pay the first premium directly to the insurer. HealthCare.gov notes that coverage starts January 1 for people who enroll by December 15 and pay their first premium.
Real-world scenarios
A Phoenix family renewing their Marketplace plan
They update income, see a larger tax credit than expected, and move from Bronze to Silver for lower deductibles at nearly the same net premium. Staying in the ACA Marketplace was right; staying on autopilot was not.
A 1099 videographer in Roosevelt Row
His income swings month to month. He estimates conservatively, sets a reminder to update HealthCare.gov midyear, and saves part of each payment toward his deductible.
A Laveen couple switching from COBRA
COBRA was expensive, and during Open Enrollment they can choose a Marketplace plan for any reason. They line up the new plan to start January 1 before ending COBRA.
After you enroll
- Save your confirmation and the plan's summary of benefits
- Set up automatic premium payments
- Watch the mail for your ID cards and any document requests from HealthCare.gov
- Report income or household changes during the year
