How South Carolina Payroll Taxes Work

South Carolina residents pay both state and federal income taxes, plus FICA taxes. The state taxes are calculated using graduated brackets on wages.

Net pay = Gross - Federal tax - State tax - SS (6.2%) - Medicare (1.45%) - deductions
Social Security applies to first $176,100 (2025 wage base)
Additional 0.9% Medicare surtax on wages over $200,000

How to Use the Calculator

1
Choose salary or hourly
Click the tab that matches how you are paid. Salary mode takes an annual gross figure. Hourly mode takes a pay rate and weekly hours.
2
Enter your gross pay
For salary, type your annual gross before any deductions. For hourly, enter your rate and how many hours you work per week on average.
3
Set pay frequency
Choose weekly, bi-weekly, semi-monthly, monthly, or annually. This changes how results are displayed but does not affect tax calculations.
4
Select your filing status
Single, Married Filing Jointly, or Head of Household determines your federal standard deduction and which tax brackets apply to your income.
5
Add pre-tax deductions (optional)
Enter your 401(k) percentage and any pre-tax health insurance premium per month. These reduce your federal taxable income. Check whether they also reduce your South Carolina state taxes.
6
Read your results
Results show your take-home pay broken down by deduction. Switch the period tabs to toggle between monthly, bi-weekly, weekly, and annual views.

Example Calculation

Suppose you earn $65,000 per year in South Carolina, file as single, and have no pre-tax deductions.

Gross annual pay$65,000
Federal taxable income ($65,000 - $14,600 standard deduction)$50,400
Federal income tax-$6,002
South Carolina state tax-$2,699
Social Security ($65,000 × 6.2%)-$4,030
Medicare ($65,000 × 1.45%)-$943
Estimated net annual take-home$51,327
Monthly take-home~$4,277

What Does the Result Mean?

In this example, the effective total tax rate is about 21.0% of gross pay. Progressive federal brackets mean you only pay the higher rate on income above each threshold, so your effective federal rate is lower than your top bracket.

Disclaimer: This calculator provides estimates for informational purposes only. Your actual paycheck may differ due to employer-specific withholding, garnishments, or benefits not captured here. Consult your HR department or a tax professional for exact figures.

Common Mistakes to Avoid

Entering monthly salary instead of annual

The salary field expects your full annual gross. If you enter your monthly pay, the result will be roughly 92% too low. Multiply your monthly pay by 12 before entering.

Forgetting pre-tax deductions

Health insurance premiums and 401(k) contributions paid with pre-tax dollars reduce your federal taxable income. Skipping these overstates your estimated federal tax.

Confusing your top South Carolina bracket rate with your effective rate

South Carolina uses graduated tax brackets, so only income above each threshold is taxed at the higher rate. Your effective state tax rate will always be lower than your top marginal bracket. Use the calculator to see your actual effective rate.

Using the wrong filing status

Married filing jointly nearly doubles the standard deduction ($29,200 vs $14,600 for single in 2025). Using the wrong status produces meaningfully different federal tax estimates.

Expecting this to match your exact paycheck

Employer-specific items like union dues, FSA contributions, life insurance premiums, or garnishments are not included here. Use this as a baseline, then verify with your actual pay stub.

Frequently Asked Questions

South Carolina uses three tax brackets. The first $3,460 of taxable income is taxed at 0%, income from $3,461 to $17,330 at 3%, and income above $17,330 at 6.4% for 2025. South Carolina has been phasing its top rate down from 7% toward 6% over several years.

Paycheck Tip
