Health insurance open enrollment opens November 1: what self-employed vendors should know

If your health coverage doesn't come through a job, a spouse's job, or a program like Medicaid or Medicare, November 1 is the date that actually matters on your calendar this fall — not a Market date, an application deadline. That's when Marketplace open enrollment opens, and for most self-employed people it's the only chance all year to sign up for a new plan or switch an existing one without waiting for a qualifying life event. A lot of vendors running a full production and show schedule right now let the window pass them by simply because nothing on their calendar flagged it.

The window, and the date inside the window that actually matters

Open enrollment for Marketplace coverage runs November 1 through January 15 nationally, though a handful of state-run exchanges keep their own windows open longer. Inside that stretch, one earlier date matters more than the closing one: enroll by December 15 and coverage starts January 1. Enroll any time after that, up to the January 15 close, and coverage doesn't start until February 1 — a full extra month without the plan you picked. If continuous coverage matters to you, the December 15 date is the one to circle, not January 15.

Outside this window, you generally need a qualifying life event — losing job-based coverage, marriage, a new baby, a move to a new state — to enroll or make changes. Open enrollment is the one stretch of the year that doesn't require an explanation.

The part that's different when your income doesn't come from a paycheck

A W-2 employee's income is predictable enough that estimating next year's earnings for subsidy purposes is usually a formality. A vendor's isn't. Marketplace subsidies — the premium tax credits that lower your monthly payment — are based on your projected income for the coverage year, and for a self-employed person that means net income after business deductions, not your gross sales. Overestimate it and you leave savings on the table all year. Underestimate it and you can owe money back at tax time when your actual Schedule C numbers come in higher than what you projected back in November.

That's a real planning problem for a business where a meaningful share of the year's income lands in a six-to-ten-week holiday run that hasn't happened yet when you're filling out the application. A few things that help:

• Start from last year's actual net income, not a hopeful guess at this year's. Your Tracker's season-money and expense totals from last year are a more honest starting point than optimism about this holiday season.
• Account for the deductions you actually take — booth fees, mileage, supplies, the home-studio portion of your space — since subsidy eligibility runs on net income, the same number that lands on your Schedule C, not what the card reader rang up.
• Expect to true this up at tax time. The premium tax credit reconciles on Form 8962 when you file, comparing what you estimated against what you actually earned. A wildly off estimate either direction is correctable, but it's smoother to get reasonably close up front than to be surprised by a repayment in April.

Why premiums look different than they did a couple of years ago

The extra premium tax credit amounts that lowered a lot of people's monthly payments since 2021 were reduced starting this year, so the discount on many plans is smaller than it was the last few times you enrolled, even though the underlying Marketplace program — and standard, income-based premium tax credits — are still in place for people who qualify. Whether anything about this changes again before your own enrollment window is the kind of thing that's genuinely moved in Congress recently, so it's worth checking the current numbers directly on healthcare.gov, your state's exchange, or with a licensed agent rather than assuming last year's premium or subsidy amount still applies.

Other coverage is worth a quick look too

The Marketplace isn't the only route, and depending on your situation, it may not be the cheapest:

• A spouse's employer plan usually beats an individual Marketplace plan on cost, if one's available to you — their open enrollment may run on a different calendar than the Marketplace's, so check that date too.
• COBRA, if you left a job with coverage recently, lets you keep that same plan temporarily, generally at a higher cost than you paid as an employee.
• Short-term or health-sharing-ministry plans show up in a lot of search results aimed at the self-employed. They're usually cheaper, and usually for a reason — most aren't required to cover pre-existing conditions or the same set of essential benefits a Marketplace plan has to, so read exactly what's excluded before counting on one.

A quick disclaimer

This is general information, not health insurance, tax, or legal advice. Marketplace rules, subsidy amounts, and state-specific deadlines change — sometimes within a single enrollment season — so confirm your state's current window and your own likely subsidy eligibility directly on healthcare.gov, your state's exchange, or with a licensed health insurance agent before you enroll, and talk to a CPA if you're unsure how to project your self-employment income for the application.

The short version

If you buy your own coverage, open enrollment opens November 1 and runs through January 15, but enrolling by December 15 is what actually gets you continuous coverage starting January 1. The harder part for a vendor isn't the calendar — it's projecting a year of self-employment income accurately enough to get your subsidy estimate close, using real numbers from last season instead of a guess made before the holiday run even starts.

A monthly premium is as real a cost of running your business as a booth fee, and it belongs in the same take-home math. The Tracker's expense and season-money tools keep that whole picture in one place, and Artisans Almanac is free to try for 30 days at artisansalmanac.com.
