Updated August 2026 for 2026 and 2027 coverage.

You may qualify for help paying for health insurance in South Carolina if your household income falls roughly between 100% and 400% of the federal poverty level and you enroll through the Marketplace. Household size, income, and what you are offered at work all move the answer, so it has to be run for your situation. What nobody can do is promise you a number before asking those questions.

Here is how the help actually works, and the three places people lose it.

What is a premium tax credit?

It is a discount on what you pay each month for a Marketplace plan, and it is the main form of help available in South Carolina.

You can take it in advance, where it goes straight to the insurance company and lowers your bill, or take the whole thing as a credit when you file. Almost everyone takes it in advance, which is why estimating your income correctly matters so much. Either way it gets reconciled on your tax return against what you actually earned.

Do I qualify?

Three things decide it:

  • Household income, measured against the federal poverty level for your household size. The dollar figures change every year, so the percentages are the durable way to think about it.
  • Household size, which is generally the people on your tax return, not the people under your roof.
  • What you are offered at work, covered below.

You also have to buy through the Marketplace. A plan bought directly from a carrier, however good it is, cannot carry a premium tax credit.

What if my job offers coverage?

Then usually no credit, provided that coverage is considered affordable and meets minimum value. Affordability is measured against a percentage of household income that the IRS resets each year.

One change worth knowing, because it went the right way and got very little attention: since 2023, affordability for your spouse and children is judged on the cost of family coverage, not employee-only coverage. Under the old rule a plan could be called affordable because the employee’s own share was cheap, while adding the family cost a fortune, and nobody in that family could get a credit. That gap was closed. If you were told years ago that your family did not qualify, that answer may be out of date.

The 400% cliff is back

This is the biggest change for 2026, and the one most likely to catch a current customer.

From 2021 through 2025, a temporary rule kept help available above 400% of the federal poverty level. It expired at the end of 2025. The line is hard again: one dollar over and the credit does not shrink, it disappears.

It lands hardest on people in their fifties and early sixties, where full-price premiums are highest and the drop is steepest. If your income lands anywhere near that line, it is worth a conversation before you enroll rather than after you file.

What happens if you estimate your income wrong

You settle up at tax time either way. Earn less than projected and you get the difference back. Earn more and you repay the excess.

What changed is the repayment side. The old rules capped how much you had to pay back. Those caps are gone starting with 2026 coverage, so you repay every dollar you were not entitled to. For anyone with variable income, a good year can turn into a real tax bill.

The fix is not to lowball the estimate. It is to report changes during the year as they happen so the credit adjusts along the way. If your income moves around, our guide to self-employed health insurance in South Carolina gets into estimating it.

The second subsidy most people miss

Premium tax credits get all the attention, but cost-sharing reductions are the other half, and they lower your deductible, copays, and out-of-pocket maximum instead of your monthly payment.

They are generally available under 250% of the federal poverty level. The catch: they only attach to silver plans. Someone eligible for strong cost-sharing reductions who picks a bronze plan to save on the monthly payment can end up with a silver plan available to them that has both a lower deductible and a similar monthly cost. That trade gets made wrong constantly, because the monthly number is the one on the screen.

Do not let it auto-renew this year

Review and update your Marketplace application every year. Automatic reenrollment may continue in some circumstances, but your plan, premium, tax credit, network, and eligibility can change. A plan that quietly rolls over can roll over with a different credit attached, and the first sign is a January invoice that looks nothing like December’s.

Between that and the cliff returning, this is the worst year in a while to skip the review. Our Open Enrollment guide covers what to compare. Open Enrollment for 2027 coverage runs November 1 through December 15, 2026.

If your income is below the poverty level

South Carolina has not expanded Medicaid, which means some adults earning under 100% of the federal poverty level fall into a gap: too much income for South Carolina Medicaid, not enough to qualify for a premium tax credit. It is the one situation where earning slightly more can open the door rather than close it. We cover it in more detail in our piece on whether there is a penalty for going uninsured.

If you think that is you, call before you assume. Household size and where your income comes from both change the answer.

Frequently asked questions

Do I qualify for a health insurance subsidy in South Carolina? You may, if your household income lands roughly between 100% and 400% of the federal poverty level and you buy through the Marketplace rather than directly from a carrier. Household size, income, and whether you are offered coverage at work all factor in, so the honest answer is that it has to be run for your specific situation. Anyone who quotes you a subsidy amount before asking those questions is guessing.

What is the 400% cliff, and why does it matter again? From 2021 through 2025 a temporary rule extended help above 400% of the federal poverty level. That rule expired at the end of 2025, so the hard line is back: one dollar over 400% and the credit goes to zero, not down gradually. It bites hardest in your fifties and early sixties, when full-price premiums are highest.

Can I get a subsidy if my job offers health insurance? Usually not, if that coverage is considered affordable and meets minimum value. Affordability is measured against a percentage of household income that the IRS resets each year. One thing that did change in your favor: since 2023, affordability for your spouse and children is judged on the cost of family coverage rather than employee-only coverage, so families priced out of a plan that looked cheap on paper may now qualify.

What happens if I estimate my income wrong? You settle up at tax time. If you earned less than you projected you get the difference back; if you earned more, you repay the excess credit. Starting with 2026 coverage the old caps on repayment are gone, so you repay all of it. That is why reporting income changes during the year matters more than it used to.

What are cost-sharing reductions? A second kind of help that lowers your deductible, copays, and out-of-pocket maximum rather than your monthly payment. They are generally available under 250% of the federal poverty level, and here is the catch that costs people real money: they only attach to silver plans. Picking bronze for the lower monthly cost can quietly forfeit them.

What our help costs you

Nothing. We are paid by the health plan, not by you, and the price of a plan is the same whether you enroll through an agent or on your own. What you get for it is someone who checks the silver comparison, watches the 400% line, and picks up the phone in March when something changes.
