Leaving a dealership or shop to work out of a van is usually a jump in take-home pay and an immediate loss of employer health coverage. Those two things happen in the same week, and the second is easy to underestimate.
Losing Employer Coverage Is a Qualifying Life Event
This is the useful part of the timing. When you leave a job with health insurance, you get a special enrollment period — generally 60 days — to take a marketplace plan without waiting for open enrollment.
That window is short and it does not reopen. Missing it means waiting until the next open enrollment with no coverage in between, which for someone lifting transmissions on a driveway is a real exposure. Sort the plan in the same fortnight as the van, not afterwards.
Where a Couple Lands at $63,000
At $63,000 of net profit with a spouse, the 2026 poverty guideline for a household of two is $21,150, so 400% is $84,600. You are around 298% — inside subsidy range, with the benchmark Silver contribution capped at 9.96% of income.
The same $63,000 as a single filer would be about 403% of $15,650 and would fall just outside. A spouse changes the answer completely at this income.
Self-employment tax is $63,000 × 0.9235 × 0.153, roughly $8,902, so about $4,451 comes off before that comparison, plus premiums.
The Van Is a Deduction, and Deductions Move Your Subsidy
Mileage or actual vehicle costs, tools, diagnostic equipment and insurance all reduce net profit, and net profit is the figure subsidies run on. A year with a van purchase or a major tool investment produces a lower net profit and a larger credit.
That is not a loophole; it is what net profit means. But it does mean keeping proper records is worth money twice over — once on the tax return and once on the premium.
If Your Spouse Has an Employer Plan, Check Before You Enrol
If a spouse is offered coverage at work that counts as affordable and covers the family, you may be ineligible for a premium tax credit — and it turns on the offer, not on whether anyone enrolled. It also blocks the self-employed premium deduction for any month you were eligible. Check what the offer actually is before assuming either way.
Road Time Is Part of the Risk
Mobile work means driving between jobs all day. Auto insurance covers the vehicle and liability; it does not cover your health beyond limited medical payments coverage. The plan feature worth comparing is emergency and urgent care cost-sharing, plus network reach across the area you actually cover.
The Deduction
100% of premiums come off on Schedule 1, Line 17, above the line, up to net self-employment income, for any month no employer plan was available to you.
