Income based health insurance means your Marketplace price depends on your household income, not just the plan you pick. For 2027 coverage, a tax credit caps your share of the benchmark silver plan at 2.15% to 10.22% of income, between 100% and 400% of the poverty level. Below 250%, silver plans also cut deductibles.
- The Marketplace uses modified adjusted gross income (MAGI) for your whole tax household, not just your wages.
- For 2027 coverage, your share of the benchmark silver plan ranges from 2.15% to 10.22% of income, according to the IRS.
- Credits stop above 400% of the poverty level, which is $63,840 for one person and $132,000 for a family of four.
- Starting with tax year 2026, there's no cap on repaying extra advance credits, so report income changes fast.
- From 2028 coverage on, the Marketplace must verify income before credits start, which ends automatic renewals with credits.
What income based health insurance means
Income based health insurance isn't a separate kind of plan. Instead, it's how Marketplace prices work when you qualify for help. For example, two neighbors can pick the same silver plan and pay very different premiums, because the tax credit follows each household's income.
Two kinds of help
- Works on any metal tier
- Based on your expected income
- Settled when you file taxes
- Silver plans only
- Income up to 250% of the poverty level
- Nothing to repay at tax time
So who gains the most? Hourly workers with uneven pay, freelancers, families with kids and early retirees living on savings all benefit. If you've left work before 65, see our guide for retirees not yet on Medicare.
What counts as modified adjusted gross income
The Marketplace uses modified adjusted gross income, or MAGI. It starts with the adjusted gross income on your tax return. Then it adds untaxed foreign income, nontaxable Social Security and tax-exempt interest. As a result, MAGI comes close to AGI for most people.
- Wages, tips and self-employment profit after expenses
- Social Security, both taxable and untaxed, plus SSDI
- Also unemployment pay and most IRA or 401(k) withdrawals
- Interest, dividends and capital gains, including tax-exempt interest
- Net rental and royalty income
- Supplemental Security Income (SSI) doesn't count
- Neither do child support, gifts or loan proceeds
- Veterans' disability payments and workers' compensation stay out too
- Also leave out qualified Roth IRA withdrawals
Whose income counts toward MAGI
Count everyone in your tax household. That means you, your spouse if you file jointly, and anyone you claim as a dependent. However, a dependent's income counts only if they must file a tax return. Alimony also counts only for divorces finalized before 2019.
Income based health insurance at every income level
Think of it as a ladder. Medicaid sits at the bottom in expansion states, while silver plans with extra savings fill the middle. Then the tax credit alone covers the upper rungs.
| Poverty level | What you can get for 2027 coverage |
|---|---|
| Below 100% | Medicaid in expansion states, but a gap may exist elsewhere |
| 100% to 138% | Medicaid in expansion states; otherwise silver at 94% plus a credit |
| 138% to 150% | Silver at 94% plus a credit |
| 150% to 200% | Silver at 87% plus a credit |
| 200% to 250% | Silver at 73% plus a credit |
| 250% to 400% | Credit only, so your share runs 8.66% to 10.22% |
| Over 400% | Full price, since no credit applies |
The silver percentages show the average share of covered costs the plan pays. A standard silver plan, by comparison, pays about 70%.
What one person pays for the benchmark plan
These monthly shares follow the IRS table for 2027 coverage. Your credit equals the benchmark price minus your share. So when premiums in your area run high, the credit grows with them.
Income based health insurance for a family of four
Above $132,000, the credit ends completely for a family of four. If that's you, read about coverage choices when you earn too much.
A licensed Vivna agent can check your income, apply your credit and compare plans side by side, at no cost to you.
How income-based coverage reacts to a raise
Your credit rests on an estimate, so mid-year changes matter. When you report a raise right away, the Marketplace adjusts your monthly credit. However, if you wait, the gap shows up at tax time instead.
Changes to report right away
- A raise, a bonus or a new job
- Also a move to a new state or county
- Marriage, divorce or a new baby
- Gaining job-based coverage or Medicare
Some of these changes also open a special enrollment period, so read about coverage changes after a major life event.
How the tax-time settle-up works
- Get Form 1095-A
The Marketplace sends it early in the year after your coverage.
- File Form 8962
Then compare the credit you took with the credit your real income earned.
- Settle the difference
If you earned less, you get more back. If you earned more, you repay the extra.
Starting with tax year 2026, there's no cap on repaying extra advance credits. So if your income tops 400% of the poverty level, you repay every dollar. Also, from 2028 coverage on, the Marketplace must verify your income before credits start.
Worked example: a new job in July
Jordan is a made-up single adult who estimates $30,000 for 2027 and takes the full advance credit. In July, a new job pushes the year's income to $66,000. That's over the 400% line of $63,840, so Jordan qualifies for no credit for the year. Because the repayment cap is gone, Jordan repays all of it at tax time. Had Jordan reported the job in July, though, the Marketplace could have stopped the credit early and shrunk that bill.
How to estimate your income
Start with last year's tax return. Then adjust for anything you know will change, such as a new job, a raise or retirement. Finally, divide the total by 12 to sanity-check the monthly number against your pay.
Tips for self-employed and seasonal workers
- Use profit after expenses, not gross receipts
- Next, subtract the deductible part of self-employment tax
- Count slow months, not just busy ones
- Traditional IRA and HSA contributions can also lower MAGI
For a worked example, see how freelancers estimate changing income.
Early retirees: watch your withdrawals
If you retire before 65, your income often comes from savings. Traditional IRA and 401(k) withdrawals count toward MAGI, while qualified Roth withdrawals don't. So the accounts you draw from can change your credit. For example, a single retiree with $47,880 of MAGI, or 300%, pays about $408 a month for the benchmark plan. However, pulling another $16,000 from a traditional IRA would push MAGI to $63,880 and erase the credit. Talk with a tax professional before you move money.
If your income swings a lot, you can take less than your full credit each month. Then you get the rest back as a refund when you file. On the phones, we suggest this to commission and gig workers, because it cuts the risk of a surprise tax bill.
Timing matters too. For 2027 coverage, Open Enrollment runs November 1 to January 15 on HealthCare.gov, and you should enroll by December 15 for a January 1 start. Learn how the yearly enrollment window works, then bring your estimate to the call.
Mistakes that raise your costs
- Choosing bronze when a silver plan with extra savings costs only a little more
- Reporting gross receipts instead of net profit
- Waiting until tax season to report a raise
- Forgetting untaxed Social Security or tax-exempt interest
- Never checking Medicaid or CHIP for your kids
Estimate your income honestly, then update it the day it changes.The rule our licensed agents repeat most to Marketplace clients
Which plans to price first
Price silver first for the extra savings.
Compare bronze and gold with your credit applied.
Shop full-price plans, including HSA-eligible bronze.
To weigh the tiers, read how the metal tiers split your costs. Earning under the poverty line? Then see options when Medicaid isn't available. When you're ready, compare ACA and private plans in your ZIP code, or call 888-730-6001.
Income based health insurance: FAQs
What does income based health insurance mean?
It means your Marketplace premium and, on silver plans, your deductible depend on your household income. For 2027 coverage, a premium tax credit limits your share of the benchmark silver plan to between 2.15% and 10.22% of income. So lower incomes get bigger credits and richer silver coverage.
Does Social Security count toward MAGI?
Yes. The Marketplace counts Social Security retirement and disability benefits, both the taxable and untaxed parts. However, Supplemental Security Income (SSI) doesn't count. So a retiree living on Social Security plus savings withdrawals should add both when estimating income for the year.
What if I earn more than I estimated?
You repay the extra credit when you file your taxes. Starting with tax year 2026, there's no repayment cap, so you could owe the full difference. If your income tops 400% of the poverty level, you repay every dollar. That's why you should report a raise to the Marketplace as soon as it happens.
What if I earn too little for a tax credit?
Below 100% of the poverty level, you usually can't get a credit. In expansion states, though, Medicaid covers most adults up to 138% of the poverty level. In the 10 states that didn't expand, some adults fall into a gap. Even so, kids can often still qualify, as our guide to health coverage choices for your children explains.
Does buying through an agent cost more?
No. Marketplace premiums are the same whether you enroll alone or with a licensed agent. Vivna's agents can estimate your income, apply your credit and compare plans from 50+ carriers. You can also browse our answers on enrollment and eligibility any time.
