About the ACA Subsidy Estimator
For anyone self-employed, health coverage is the single largest line item nobody can price in advance. The marketplace shows you a sticker premium; what you actually pay depends on a premium tax credit calculated from your household size, your projected income, and a benchmark plan you never necessarily buy. This tool runs that calculation properly.
2026 matters more than most years, because the enhanced subsidies introduced in 2021 expired on 31 December 2025. The pre-2021 structure is back, and with it the 400% subsidy cliff: at 400.00% of the federal poverty line you still receive a credit, and at 400.01% you receive nothing. For a self-employed household near that line, a single late-December invoice can cost more than it earns. The cliff visualiser shows you exactly where your own edge sits.
Every constant here comes from a primary source and is dated. The applicable percentage table — 2.10% rising to 9.96% across the income bands — is taken directly from IRS Revenue Procedure 2025-25, which sets it for tax years beginning in 2026. The poverty guidelines are the 2025 HHS figures published in the Federal Register, which are the ones the marketplace uses for 2026 coverage. Everything runs in your browser; nothing you type is transmitted or stored. This is educational modelling, not tax or insurance advice — verify with healthcare.gov and a tax professional.
Annual premium tax credit across a range of incomes for your household. The red line is 400% of the poverty line, where the credit falls to zero in one step. Your position is the green marker.
Premium plus expected out-of-pocket cost. Cost-sharing reductions are applied to silver automatically when your income qualifies — that is why silver can beat gold below 250% of the poverty line.
How to Use the ACA Subsidy Estimator
Enter the number of people on your tax return — not the number who need coverage, which is often different — then your projected modified adjusted gross income for the coverage year. For the self-employed this is net profit after business expenses, not revenue, and getting it wrong in either direction is the most common source of a nasty April surprise. The benchmark premium is estimated from the ages you supply; replace it with your real second-lowest-cost silver plan from healthcare.gov and the answer becomes exact.
What Changed for 2026
From 2021 through 2025, enhanced subsidies did two things: they lowered the expected contribution at every income level, and they removed the cliff by capping premiums at 8.5% of income no matter how much you earned. Both expired on 31 December 2025. For 2026 the original structure is back:
- Expected contributions run from 2.10% of income below 133% of the poverty line up to 9.96% between 300% and 400%.
- Above 400% of the poverty line there is no credit at all.
- The 9.96% figure also serves as the employer-coverage affordability threshold for 2026.
Those percentages are not estimates — they come from IRS Revenue Procedure 2025-25, which sets the applicable percentage table for tax years beginning in 2026.
The Cliff Is a Genuine Financial Trap
Most tax thresholds are gradual: cross a bracket and only the marginal dollar is taxed higher. The ACA cliff is not gradual. It is a step function. A household at 399% of the poverty line receives a credit; the same household at 401% receives nothing. For a couple in their fifties — who face the highest age-rated premiums — that step can exceed $15,000 a year. Earning one extra dollar of consulting income in December can genuinely leave you thousands of dollars poorer.
This is why the self-employed have both the most exposure and the most control. Unlike a salaried employee, you can often influence which side of the line you land on: delay invoicing to January, accelerate deductible purchases into December, or make a deductible retirement contribution. The levers that reduce MAGI are a traditional IRA, a SEP-IRA or solo 401(k), an HSA contribution if you hold a qualifying high-deductible plan, and the self-employed health insurance deduction itself. Model it before December, not in April.
Why the Benchmark Plan Is the One That Counts
Your credit is pinned to the second-lowest-cost silver plan in your county, whether or not you buy it. The formula is simply the benchmark premium minus your expected contribution, and the resulting dollar amount can then be applied to any plan on the exchange. Two consequences follow. If you buy a cheaper bronze plan you keep the difference, and in some markets that makes bronze effectively free. If you buy gold you pay the difference out of pocket. And because the credit is a fixed dollar amount rather than a percentage, an expensive county is not necessarily a worse deal — a higher benchmark means a larger credit.
Silver Is Special Below 250%
Cost-sharing reductions are the most commonly missed part of the system. Below 250% of the poverty line, silver plans — and only silver plans — carry reduced deductibles, copays and out-of-pocket maximums. The effect is large: a standard silver plan covers about 70% of expected costs, but with cost-sharing reductions that rises to roughly 73%, 87% or even 94% depending on income. A 94% silver plan is materially better than any gold plan on the exchange, and you cannot get it by buying bronze or gold. Above 250% the reductions vanish, and a bronze plan paired with an HSA often wins for someone who expects little care.
Estimating Income When You Do Not Know It
The uncomfortable reality of freelance income is that you are asked in November to project a number you will not know until the following December. The system reconciles it: advance credits are trued up on Form 8962 when you file. Under-estimate your income and you repay some of the credit, though repayment is capped for households under 400% of the poverty line. Over-estimate and you receive the balance as a refund. Given the cliff, a deliberately conservative projection — estimating income slightly high — is usually the safer error, because it avoids the scenario where you took a full year of advance credits and then crossed 400%, at which point repayment is uncapped and the entire year’s credit comes back at once.

Frequently Asked Questions
What is the 2026 subsidy cliff?
The enhanced premium tax credits from the American Rescue Plan expired on 31 December 2025, so for 2026 the pre-2021 rules returned. Households above 400 percent of the federal poverty line get no premium tax credit at all. At exactly 400.00 percent you still receive a credit; at 400.01 percent it drops to zero, which can mean losing many thousands of dollars for one extra dollar of income.
What income counts for ACA subsidies if I am self-employed?
Modified adjusted gross income, which for most self-employed people is net business profit after deductible expenses, plus any other household income, plus tax-exempt interest and untaxed Social Security. It is not gross revenue. Contributions to a traditional IRA, a SEP or solo 401k, and HSA contributions all reduce it, which is why they are the main levers for staying under a threshold.
What is the benchmark plan and why does it matter?
Your subsidy is calculated from the second-lowest-cost silver plan available in your county, called the benchmark, regardless of which plan you actually buy. The credit equals that benchmark premium minus your expected contribution. You can apply it to any metal tier, so buying a cheaper bronze plan keeps the difference and buying a gold plan costs you the difference.
Can I deduct health insurance premiums as a self-employed person?
Yes, the self-employed health insurance deduction lets you deduct premiums above the line, up to your net self-employment income. It interacts circularly with the premium tax credit, because the deduction lowers your MAGI, which raises your credit, which lowers the deductible premium. The IRS provides an iterative method for this, and tax software handles it. Consult a tax professional.
Is a silver plan always the right choice?
Not always, but below 250 percent of the poverty line it usually is, because cost-sharing reductions are only available on silver plans and can lift the actuarial value from 70 percent to as high as 94 percent. Above that threshold the cost-sharing reductions disappear, and a bronze plan combined with an HSA often produces a lower total cost for someone who expects little medical care.
