South Carolina Income Tax Just Changed. Here Is What It Actually Means.

South Carolina just passed a major tax bill, and the headlines barely scratched the surface. Yes, the state cut its income tax rate. But the real story is bigger than that. The state also changed how income taxes are calculated, and those two things together tell a very different story than most people are hearing.

If you live in South Carolina, or you are thinking about moving here, here is what you actually need to know.

How South Carolina Income Tax Has Changed Over the Years

This did not happen overnight. For a long time, the top state income tax rate in South Carolina sat at 7%. Over the years, lawmakers worked to bring that number down, eventually reaching 6%. The new law drops the top rate again, this time to 5.21%.

So while this latest change feels significant, it is really part of a longer trend. South Carolina has been moving toward lower income taxes for years.

What the New Law Actually Did

The new law did two things worth paying attention to.

First, it created a simpler two-rate system. The first $30,000 of income is taxed at 1.99%. Anything above that is taxed at 5.21%.

Second, and this is the part most people missed, the state changed how it calculates what income is subject to tax in the first place. That change is called the South Carolina Income Adjusted Deduction, or SCIAD. This is not just a rate cut. It is a change in the math used to figure out what you owe.

That is why the impact varies from person to person.

Who Benefits and Who Does Not

According to the state's own estimates:

• 43% of South Carolinians will see a lower tax bill
• 35% will stay about the same
• 23% will see an increase

That means roughly three out of four people in the state will pay the same or less. But not everyone comes out ahead, and that is worth being honest about.

The Bigger Goal: Eliminating the State Income Tax

Here is where the story gets more interesting. This law does not just lower taxes today. It sets up a path for future tax cuts as well.

When Governor Henry McMaster signed the bill, he made a statement that said South Carolina is on a clear path to continue reducing and ultimately eliminating the personal income tax. That last part is worth paying attention to. The goal is not just 5.21%. The goal is zero.

To be clear, South Carolina still has a state income tax right now. If you move here today, you will still pay it. But the system created by this law ties future tax cuts to revenue growth. In simple terms, if more people move to South Carolina and more businesses open here, the state brings in more money and can afford to keep cutting the rate.

Lawmakers are betting on growth to get there. Future cuts are not automatic. They depend on the state actually hitting its revenue targets.

How South Carolina Compares to Florida and Tennessee

A common question from people relocating to the Greenville area is how South Carolina stacks up against states like Florida and Tennessee, which have no state income tax at all.

It is a fair comparison, but it is also a little misleading.

Florida and Tennessee do not have a personal income tax, but they still collect money. Florida relies on sales tax, tourism, hotels, tolls, and business taxes. Tennessee leans heavily on sales tax and business taxes. Neither state eliminated taxes. They just collect them differently.

So the real question is not whether South Carolina can operate without an income tax. Florida and Tennessee have already shown that is possible. The question is whether South Carolina can grow enough to follow a similar path.

And there is another piece of this that often gets missed when people focus only on income tax. Affordability is more complicated than one number.

One way economists measure overall affordability is through a cost of living index. The national average is set at 100. States below that number are generally less expensive. Based on figures shared in the video:

• Tennessee scores around 91.9
• South Carolina scores around 93.7
• Florida scores around 102

That means Tennessee is slightly less expensive than South Carolina overall. And Florida, despite having no income tax, is actually a bit more expensive than the national average. Having no state income tax does not automatically make a place more affordable to live in. Property taxes, insurance, home prices, and sales tax all factor in.

What About Property Taxes

There is also a second bill currently being discussed in the South Carolina legislature. Senate Bill 768 has not become law, but if it passes, it would lower property taxes for certain homeowners, particularly long-time South Carolina residents and seniors.

South Carolina already has some of the lowest owner-occupied property taxes in the country. If this additional bill moves forward, the state's overall tax picture could become even more favorable for certain buyers.

What This Means If You Are Moving to Greenville SC

Here is the clear version for anyone considering a move.

South Carolina still has a state income tax. The rate just dropped to 5.21%, and the calculation method changed in a way that benefits most, though not all, taxpayers. The long-term direction is toward lower taxes, but that depends on continued growth and revenue. And compared to many states people are moving from, South Carolina is already considered a relatively tax-friendly place to live.

The most important takeaway is this. Do not focus only on income tax when comparing states. Look at the full picture, including property taxes, home prices, insurance costs, and cost of living overall. When you do that, South Carolina, and Greenville in particular, holds up very well.
