Is There a Penalty for Not Having Health Insurance in South Carolina?

Updated August 2026 for 2026 and 2027 coverage.

No. There is no penalty for going without health insurance in South Carolina. The federal penalty was cut to $0 starting with the 2019 tax year, and South Carolina has never had a state penalty of its own. Nobody is going to fine you at tax time for being uninsured.

That is the whole answer. The rest of this page is about the part that costs people real money now that the fine is gone.

Is there still a federal penalty for going uninsured?

No. The Affordable Care Act’s individual mandate is technically still on the books, but the tax bill passed in 2017 set the penalty amount to zero beginning with the 2019 tax year. The requirement exists on paper with nothing attached to it.

You may still see a question about health coverage on tax forms or software. Answering it does not trigger a charge.

Does South Carolina have a penalty of its own?

No. A handful of states created their own mandates after the federal one was zeroed out, including Massachusetts, New Jersey, California, Rhode Island, and Washington D.C. Vermont asks residents to report their coverage but does not charge them for going without.

South Carolina is not one of them, and there is no serious effort underway to make it one.

One wrinkle worth knowing: those state rules follow the state, not you. If you moved to South Carolina from New Jersey in June, the months you lived in New Jersey can still matter on that state’s return. It comes up more often around here than you would think, because people move to the Midlands from all over.

Then why does the question keep coming up?

Because the penalty was real, it was expensive, and it was in the news for years. People who paid it in 2016 or 2017 remember it clearly. Nothing announced its removal with the same volume, so a rule that ended seven years ago is still shaping decisions today.

The result is a lot of people who believe they are legally required to buy something, and a smaller group who dropped coverage the moment they heard the fine was gone. Both are making the decision on outdated information.

What being uninsured actually costs here

The penalty went away. The bill did not.

Hospitals bill uninsured patients off a chargemaster rate, the list price no insurance company actually pays. An insurer has a negotiated rate; you, uninsured, do not. That is why the same appendectomy has two wildly different prices depending on whether a card was on file.

One emergency room visit, one surgery, or one diagnosis that needs ongoing treatment can cost more than several years of premiums. In South Carolina the exposure is worse than average for anyone in the coverage gap, which brings us to the harder version of this question.

South Carolina has not expanded Medicaid. Adults earning below the federal poverty level can end up caught in between: too much income for South Carolina Medicaid, which mostly covers children, pregnant women, and people who are aged, blind, or disabled, and not enough income to qualify for a Marketplace tax credit. If you think you are in that gap, do not assume. Household size and where your income comes from both change the math, and the answer is worth ten minutes on the phone.

Where the money actually is now

With the fine gone, the thing that moves your cost is the premium tax credit, a discount applied to your monthly payment for a Marketplace plan. For a lot of South Carolina households it covers a meaningful share of the bill.

Eligibility depends on your household size, your income, and whether you are offered coverage at work. Nobody can promise you a number over the phone before looking at those, and you should be skeptical of anyone who does. Our guide to health insurance subsidies in South Carolina walks through what affects where you land.

What changed for 2026 and 2027 coverage

If you have had a Marketplace plan for a few years, do not assume it still works the way it did:

• The subsidy cliff is back. From 2021 through 2025, help was available above 400% of the federal poverty level. That enhancement expired at the end of 2025. Earning one dollar over the line now means losing the credit entirely, which hits hardest in your fifties and early sixties when full-price premiums are highest.
• Excess credits are repaid in full. Take the credit in advance, earn more than you estimated, and the old caps on repayment no longer protect you. Estimating income carefully, and reporting changes mid-year, matters more than it used to.
• Auto-renewal is not the same as reviewing. 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.
• The window is shorter. Open Enrollment for 2027 coverage runs November 1 through December 15, 2026. It no longer stretches into January.

What to do before December 15

If you are uninsured because you heard the penalty went away, you heard right, and you may still be leaving money on the table. Run the numbers once with someone who can see the whole picture.

If you already have a plan, do not let it roll over unexamined this year. Between the cliff returning and the verification rules, this is the worst year in a while to skip the review. Our Open Enrollment guide covers what to compare.

If you missed the window entirely, a qualifying life event may still open a Special Enrollment Period.

Frequently asked questions

Is there a penalty for not having health insurance in South Carolina? No. The federal penalty was reduced to $0 starting with the 2019 tax year, and South Carolina has never had a state penalty of its own. Nothing on your South Carolina return charges you for going uninsured.

Which states still charge a penalty for being uninsured? A short list, including Massachusetts, New Jersey, California, Rhode Island, and Washington D.C. Vermont asks residents to report coverage without charging a penalty for going without. South Carolina is not on that list, but if you lived in one of those states for part of the year, their rules can still follow you onto that state return.

If there is no penalty, is there any reason to buy health insurance? The penalty went away. The bill did not. One emergency room visit, one surgery, or one new diagnosis can cost more than years of coverage, and hospitals bill uninsured patients at rates no insurer would pay. The risk simply moved off the tax return and onto the hospital statement.

What if my income is too low to qualify for help paying for a plan? South Carolina has not expanded Medicaid, so some adults earning under the federal poverty level fall into a gap: too much income for South Carolina Medicaid, not enough to qualify for a Marketplace tax credit. If that sounds like you, it is worth an actual conversation rather than an assumption, because household size and the source of your income both matter.

When can I enroll for 2027 coverage? Open Enrollment runs November 1 through December 15, 2026, with coverage starting January 1, 2027. That window is shorter than it used to be. Outside it you generally need a qualifying life event to enroll.
