South Carolina law lowers top marginal personal income tax rate retroactive to January 1, 2024

On July 3, 2024, Governor Henry McMaster approved H. 5100, which retroactive to January 1, 2024, lowers the top marginal personal income tax rate from 6.4% to 6.2% with graduated decreases over the next four years until the top tax rate reaches 6.0%. The tax cut is part of the 2024-25 state budget.

This is the third consecutive year that legislation was enacted to lower the state's top marginal personal income tax rate.

In 2022, S. 1087 lowered the top marginal personal income tax rate from 7% to 6.5% retroactive to January 1, 2022.

In 2023, H. 4300 further decreased the top marginal personal tax rate to 6.4% effective January 1, 2024, with gradual decreases over the next five years until the top tax rate reaches 6.0%.
