Updated July 2026 to reflect the rules for 2026 and 2027 coverage.

Picking the right health insurance in South Carolina is crucial. Among the various factors at play, understanding how taxes and credits work is paramount. These can greatly influence your choice, striking the balance between optimal healthcare and financial well-being.

Is There Still a Tax Penalty for Being Uninsured? (Short Answer: No)

You may remember the Affordable Care Act’s “individual mandate” penalty, the tax bill for going without health insurance. Here’s the good news: the federal penalty was reduced to $0 back in 2019, and South Carolina does not have a state-level penalty of its own. A handful of states (like Massachusetts, New Jersey, and California) still charge their residents for going uninsured, but South Carolina isn’t one of them.

So no, the IRS won’t fine you for skipping coverage. But before you celebrate, remember the real penalty for being uninsured never went away: one ER visit or unexpected diagnosis can cost more than years of premiums. The stakes just moved from the tax return to the hospital bill.

Tax Credits: Where the Real Money Is

The biggest tax story in health insurance today isn’t penalties. It’s the premium tax credit. Think of it as a discount on your monthly health insurance premium, and for many South Carolina families it covers most (or even all) of the bill.

To qualify, your household income generally needs to fall between 100% and 400% of the federal poverty level, and you need to enroll through the Health Insurance Marketplace.

Heads Up: The Rules Tightened for 2026 and 2027

If you’ve had a Marketplace plan for a few years, don’t assume things work the way they used to. Several big changes kicked in recently:

  • The “subsidy cliff” is back. From 2021 through 2025, help was available even above 400% of the poverty level. That enhancement expired at the end of 2025. Now, earning even one dollar over the 400% line means losing the entire credit, so income planning matters more than ever, especially for folks in their 50s and early 60s where full-price premiums run highest.
  • You must repay every dollar of excess credit. If you take the credit in advance and your income ends up higher than you estimated, the old rules capped how much you had to pay back at tax time. Those caps are gone. Starting with 2026 coverage, you repay the full overage. Estimating your income accurately (and reporting changes mid-year) is now a big deal.
  • No more coasting on auto-renewal. New verification rules mean you need to actively confirm your income and eligibility every year to keep your tax credits. Letting your plan quietly renew itself can cost you your subsidy.
  • A shorter window to enroll. Open Enrollment for 2027 coverage runs November 1 through December 15, 2026 in South Carolina. The window no longer stretches into January like it used to.

Weighing It All in Your Decision

There’s no tax penalty pushing you to buy coverage anymore, but there are thousands of dollars in tax credits pulling you toward it, and some new tripwires (the 400% cliff, full repayment of excess credits) that make getting the details right genuinely important.
