How to Buy ACA Marketplace Health Insurance as a Self-Employed Person

The Health Insurance Marketplace is where most self-employed people buy individual health coverage. The process is straightforward if you prepare your income estimate and compare plans on total cost.

Step 1: know when you can enroll

Open enrollment for the following year generally begins on November 1, but end dates have varied by state and year. Check HealthCare.gov or your state exchange for current dates. Outside that window, you need a qualifying life event, such as losing other coverage, moving, getting married or having a baby, and you usually have 60 days to act.

Step 2: estimate your income

Subsidies are based on your expected modified adjusted gross income for the year. For freelancers, that is your net profit after half of self-employment tax and other adjustments, plus any other income. Your estimate does not have to be perfect, but it should be realistic. Update the marketplace during the year if your income changes significantly.

Step 3: understand the subsidies

Premium tax credit: lowers your monthly premium. You can take it in advance or claim it when you file your taxes.
Cost-sharing reductions: lower deductibles and out-of-pocket costs, but only if you pick a silver plan and your income is within a range set by federal rules.

Subsidy rules have changed in recent years, so use the marketplace calculator for current amounts. It is important to reconcile advance payments on Form 8962 when you file. If you received more credit than you qualify for, you may have to repay all or part of the difference, depending on the rules that year.

Step 4: choose a metal tier

Tier	You pay (roughly)	Best for
Bronze	Low premium, high deductible	Healthy people who want catastrophe protection, and HSA-eligible plans
Silver	Moderate premium and deductible	Subsidy-eligible people who may benefit from cost-sharing reductions
Gold	Higher premium, lower deductible	Regular medical needs
Platinum	Highest premium, lowest deductible	Frequent care, when available

The tiers describe how costs are split, not the quality of care.

Step 5: compare plans on total cost

Look beyond the premium. For each plan, calculate premium times twelve plus the deductible and the out-of-pocket maximum you might face. Then check:

Is your doctor in the network?
Are your prescriptions covered and at what tier?
What are copays for visits, urgent care and specialists?
Is the plan HSA-eligible, if you want an HSA?

Step 6: apply and confirm coverage

Create an account, enter your household and income information, select a plan and pay your first premium. Coverage does not start until the insurer receives it. Keep copies of your confirmation and your Form 1095-A when it arrives in January.

Step 7: deduct your premiums

If you are self-employed with a net profit and not eligible for another employer plan, you can deduct the premiums you pay. Because the premium tax credit and the deduction affect each other, tax software or a professional should calculate both.

Mid-year income changes

If your income rises or falls by a large amount, update the marketplace so your advance credit matches reality. A freelancer with a big year may owe back part of the credit, while one with a slow year may be entitled to more.

Common mistakes

Underestimating income to get a bigger subsidy, then owing it back at tax time.
Picking the lowest premium and ignoring the deductible.
Forgetting to report income changes.

Frequently asked questions

Do I need a tax professional?
