Deciding where to buy your 2027 marketplace plan, Healthcare.gov, eHealth, HealthSherpa or an Arizona advisor, changes more than convenience: it can affect which health plans you're shown, your premium tax credit, and who helps you when a claim goes wrong. For Arizona shoppers weighing Individual Insurance options, the difference is worth understanding before open enrollment opens.

What's the Difference Between Healthcare.gov, eHealth, and HealthSherpa?
Whether you check Healthcare.gov, eHealth, HealthSherpa or an Arizona advisor first, the real question is who actually shows you Arizona's full health insurance marketplace. Healthcare.gov is the federal government's health insurance marketplace, the official .gov website built and run by the Centers for Medicare & Medicaid Services. Every application submitted there checks directly against IRS and Social Security data to calculate your subsidy. eHealth and HealthSherpa work differently. Both are private sector companies operating as CMS-approved enrollment platforms that connect to the same underlying marketplace data as Healthcare.gov, but the website, the plan search tools, and the customer support are built and run by the company itself, not a government agency. HealthSherpa in particular licenses its enrollment technology to agents across the United States, including many Arizona advisors, so the same integrated system that powers HealthSherpa's own site at HealthSherpa.com often sits quietly behind a local advisor's private enrollment portal too. eHealth, by contrast, runs its own branded platform and mostly connects shoppers straight to its own network of agents rather than licensing the technology out. Plenty of people just type "healthcare gov" into a search bar instead of the full web address, but that search still lands on the same official government site described above.
Is It Free to Buy Through eHealth or HealthSherpa, or Do They Cost More Than Healthcare.gov?
Buying an ACA plan through eHealth or HealthSherpa is free to the applicant. Neither platform charges an enrollment fee. Instead, the insurance company pays a small commission once you're enrolled, the same commission structure that funds a local Arizona advisor's time. Premiums themselves are set by the carrier and filed with the Arizona Department of Insurance, so whatever a company like Blue Cross Blue Shield of Arizona offers for a given Bronze or Silver plan costs the same monthly premium whether you enroll on Healthcare.gov, through eHealth, through HealthSherpa, or through an advisor. Price is not the variable; access and support are. This is worth repeating because it's the single most common misconception self-employed shoppers bring into open enrollment: assuming the "free" private sites must be marking plans up somewhere to cover their own costs.
Why the Same Plan Can Show Different Prices
When eHealth or HealthSherpa displays a different number than Healthcare.gov for what looks like the same plan, it's usually one of three things: the subsidy estimate hasn't finished recalculating, the site is defaulting to a different metal tier or provider network before you adjust filters, or a dental or vision add-on got bundled into the quote automatically. Always compare the exact plan ID and confirm your household income and subsidy amount match across sites before assuming one is cheaper.
Is a Local Arizona Advisor Better Than an Online Marketplace Like eHealth or HealthSherpa?
For many self-employed workers and families, yes, mainly because of what happens after enrollment. An online marketplace can show you plans and take your application, but it usually can't help you when a claim gets denied, a prescription isn't covered, or your income changes mid-year and your subsidy needs adjusting. A local advisor typically stays reachable once coverage starts, which matters when clients need help mid-year, often at no extra cost to you. That ongoing relationship is the real distinction: an online platform closes the loop the moment your application submits, while an advisor who knows Arizona's plan networks stays available for as long as you're covered.
How to Tell If You're Seeing Every Plan Available in Arizona
Neither an online platform nor an individual agent can show you a carrier they aren't contracted with. That's true of eHealth, HealthSherpa, and a local advisor alike, agents only earn commission on carriers they hold an active appointment with, so a platform's plan list often reflects its partnerships more than the full Arizona market. The direct fix: ask "Which carriers are you appointed with in my county?" and ask to view every plan available before you settle on one.
Does Using an Arizona Advisor Cost More or Change Your ACA Subsidy?
No. A licensed Arizona advisor is paid the same way eHealth and HealthSherpa are, through carrier commission, so working with one does not raise your premium or reduce your premium tax credit. For Self-Employed applicants whose income moves month to month, that ongoing relationship often matters more than the enrollment itself. That kind of income projection is exactly where self-employed marketplace enrollment gets complicated, since your estimated annual income drives both your subsidy and your eventual tax reconciliation. Getting that estimate close to accurate up front is usually easier with someone who can walk through last year's actual numbers with you.
When Should You Use Healthcare.gov Directly Instead of a Private Site or a Local Advisor?
Healthcare.gov directly makes sense when you already know exactly which plan and carrier you want, and you're comfortable uploading income and identity documents yourself through the standard federal applications process. Some states run their own exchange, but Arizona uses Healthcare.gov, so there's no separate state applications process to navigate here. It's also the option to use if you don't want an agent of record attached to your file, or if your household needs a program the .gov website handles directly, like certain Medicaid or CHIP eligibility determinations tied to the same application. If none of those apply to your situation, a guided option usually saves more time than it costs.
Healthcare.gov, eHealth, HealthSherpa or an Arizona Advisor: Which Wins for 2027 Open Enrollment?
There's no single right answer, only the right fit for how much support you want. Browse Healthcare.gov, eHealth, HealthSherpa or an Arizona advisor if you're comparing prices for the first time, but plan to finish your enrollment with whichever option actually answers questions once you're a paying member, not just at signup. For most self-employed individuals, families, and small business owners in the Phoenix area, that tends to be a local advisor who already knows Arizona's carrier networks and stays reachable after November, since open enrollment is a small part of the year but coverage questions come up all twelve months.
Frequently Asked Questions
Is HealthSherpa the same thing as Healthcare.gov?
No. Healthcare.gov is the government's own marketplace website. HealthSherpa is a private sector technology company approved by CMS to enroll people into the same marketplace plans through its own platform. Your plan options and subsidy calculation come from the same federal data either way, but HealthSherpa's website, design, and support team belong to the company, not a federal agency.
Does eHealth charge extra fees compared to buying a plan directly from the marketplace?
No. eHealth doesn't charge applicants a fee to browse or enroll. It earns a commission from the insurance company once you're enrolled, which is already built into every plan's premium industry-wide. Your monthly premium is the same whether you buy through eHealth, Healthcare.gov, or an Arizona advisor, so there's no cost penalty for using the private platform.
Can a local Arizona advisor get you the same premium tax credits as Healthcare.gov?
Yes. Premium tax credits are calculated from the same federal formula and the same household income data regardless of who submits your application. A licensed Arizona advisor uses the same eligibility system Healthcare.gov uses, so your subsidy amount doesn't change based on who helps you enroll, only your income and household size determine that.
Do eHealth and HealthSherpa sell every ACA marketplace plan available in Arizona?
Not necessarily. Both platforms only display plans from carriers they're contracted with, similar to any individual agent. Most major Arizona carriers are represented on both platforms, but a smaller regional plan could be missing. Confirming carrier coverage directly, or asking a local advisor which carriers they're appointed with, is the only way to know you're seeing the full picture.
