Owner-Operator Subsidy Cliff Calculator for 2027
A good year can cost a driver the whole health insurance credit. Enter your net profit to see how close you are to the 400% line, and what it takes to get back under it.
Estimates only, for 2027 coverage. Benchmark prices are a national average by age; your ZIP code changes them. Uses 2026 HHS poverty guidelines and the IRS 2027 contribution scale. Not tax advice.
Why the cliff matters so much for owner-operators
For 2027 coverage there is no premium tax credit once household income passes 400% of the federal poverty level: about $63,840 for a single driver, $86,560 for a couple and $132,000 for a family of four. Owner-operator income swings with rates and miles, so a good year can push a driver a few hundred dollars over the line and cost thousands in credit.
The subsidy uses modified adjusted gross income, not gross settlements. For a sole proprietor, that starts with Schedule C net profit, minus half of self-employment tax, the self-employed health insurance deduction and pre-tax retirement and HSA contributions.
Three ways drivers get back under the line
- Solo 401(k): up to $24,500 as an employee deferral for 2026, plus catch-up from age 50, plus an employer contribution. Best for drivers with no employees.
- SEP-IRA: roughly 20% of net self-employment earnings, and it can be funded up to your tax deadline, after you know what the year actually netted.
- HSA with a bronze plan: since 2026 every bronze plan is HSA-compatible. For 2027, $4,500 single or $9,000 family, plus $1,000 at 55.

Subsidy cliff questions for drivers
What is the subsidy cliff for truck drivers in 2027?
For 2027 coverage, premium tax credits stop at 400% of the federal poverty level: about $63,840 of MAGI for a household of one, $86,560 for two and $132,000 for four. Above that line there is no credit at all, so an owner-operator a few hundred dollars over can pay the full premium.
Does the subsidy use my gross settlements?
No. It uses modified adjusted gross income. For an owner-operator filing Schedule C, that starts with net profit after business expenses, then subtracts half of self-employment tax and other above-the-line deductions such as retirement contributions and the self-employed health insurance deduction.
How much do I need to put in a Solo 401(k) to get under the cliff?
Enough to bring your MAGI below the 400% line for your household size. The calculator estimates that amount from your net profit. For 2026, the Solo 401(k) employee deferral limit is $24,500, plus catch-up from age 50, and total contributions can reach $72,000. The IRS publishes 2027 limits late in the year.
Can I wait until tax time to fix it?
Partly. SEP-IRA contributions can be made up to your tax filing deadline, including extensions, and count for the prior year. Solo 401(k) employee deferrals have to be elected by December 31. HSA contributions for a year can be made until the tax deadline too.
Is this calculator tax advice?
No. It is an estimate to show where you stand. Self-employment tax, deductions and contribution limits depend on your full return, so confirm with your tax preparer before contributing.
