How South Carolina taxes your paycheck
Here is what South Carolina takes out of your paycheck in 2026. A new law starts this year with just two tax rates. You pay 1.99% on taxable income up to $30,000, and 5.21% on the part above that.
Before the rates apply, you subtract a new state deduction: $15,000 if you're single, $22,500 for head of household, or $30,000 for married couples filing together. Each dependent also takes $4,930 off your income. The deduction gets smaller as income rises above $40,000 for single filers or $80,000 for couples. There are no state payroll programs and no local income tax.
For example, a single person earning $38,000 subtracts the $15,000 deduction, which leaves $23,000. At 1.99%, the state tax comes to about $458 for the year, or about $17.60 every two weeks.

What this estimate leaves out
- The return rounds the deduction's reduction down to the next $10. This estimate doesn't round, so it can differ by under a dollar of tax.
- Uses the 2025 dependent exemption of $4,930; the 2026 amount wasn't published when checked.
- The law allows the $30,000 bracket line to be adjusted for inflation. This uses the $30,000 the Department of Revenue lists for 2026.
- Leaves out the extra deduction for young children, retirement and age deductions, the state earned income credit (capped at $200 from 2026) and other credits.
Frequently asked questions
What are South Carolina's income tax rates for 2026?
There are two. Taxable income up to $30,000 is taxed at 1.99%, and taxable income above $30,000 is taxed at 5.21%. The top rate was 6% in 2025.
Does South Carolina still use the federal standard deduction?
No. Starting in 2026, it uses its own deduction: $15,000 for single filers, $22,500 for heads of household and $30,000 for married couples filing jointly. It shrinks as income rises and is gone at $95,000 for single filers and $190,000 for couples. This calculator shrinks it the same way.
Is there local income tax in South Carolina?
No. Cities and counties in South Carolina don't tax wages, so the state tax is the only income tax on your paycheck besides federal tax.
Does a 401(k) lower my South Carolina tax?
Yes. South Carolina starts from your federal adjusted gross income, which already leaves out traditional 401(k) and 403(b) contributions and pre-tax health premiums.
