Evidence

The enrolled South Carolina income-tax bill was signed into law on March 30, 2026. It reduces the top marginal rate to 5.21 percent, creates a 1.99 percent bracket, and says that once the initial reductions are complete, the rate continues to be reduced until the income tax rate equals zero percent if revenue-growth conditions are met.

South Carolina enacted a law that partially implements the zero-income-tax pathway, but it does not yet eliminate the income tax outright.

Contest this evidence item

Mace's campaign page continues to describe a plan to phase out South Carolina's income tax by freezing spending at a cap and returning any revenue above that threshold to taxpayers as permanent tax cuts until the income tax reaches zero.

The promise remains actively promoted on Mace's campaign site, indicating it is not yet fully resolved by her federal office service.

Assessments

partial same_term

South Carolina enacted a 2026 income-tax law that lowers rates and creates a conditional path for further reductions toward zero, so the policy outcome was partially achieved but the income tax has not been eliminated and the spending-cap mechanism in the promise is not fully delivered. Because Nancy Mace is a federal representative and the cited state enactment appears to have been completed by South Carolina state officials rather than through her federal office authority or clear material sponsorship, this warrants partial credit rather than full delivery.
