How the South Carolina Paycheck Calculator Works
Essentially, the calculator starts with gross pay and subtracts each deduction step by step. First, it works out federal income tax using your filing status and the federal standard deduction. Next, it adds Social Security and Medicare, together called FICA. After that, it calculates South Carolina tax under the new 2026 rules. Finally, it subtracts voluntary deductions, such as health insurance, to reach take-home pay.
Meanwhile, payroll withholds an estimate from every paycheck, and your final bill is settled when you file your returns. As a result, a small refund or balance due is normal.
South Carolina Pay Calculator Inputs: What You Need to Enter
Before you calculate, gather a recent payslip. To begin with, enter your gross salary or hourly wage, plus your pay frequency. Then, add your filing status, because single and married filers face different deductions, and South Carolina now uses its own deduction based on that status.
Additionally, enter your dependents, because South Carolina keeps a dependent exemption for each eligible dependent. Afterward, include any pre-tax contributions, such as a traditional 401(k) or health premiums, since they lower your taxable wages and change both results. By contrast, post-tax deductions, such as Roth contributions, do not reduce your current tax bill.
Federal Taxes in Your South Carolina Paycheck
Although you work in South Carolina, federal taxes usually take the largest share of your paycheck. For 2026, the federal standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. Therefore, only income above that amount faces federal income tax in our example below.
Besides income tax, FICA applies to almost every paycheck. Specifically, Social Security takes 6.2% of wages up to the 2026 wage base of $184,500. Likewise, Medicare takes 1.45% of all wages, with no general cap. Together, they equal 7.65% for most employees.
South Carolina State Tax in 2026: Rates and Brackets Explained
South Carolina rewrote its individual income tax for 2026. Previously, the state used three brackets of 0%, 3% and 6%, after Act 228 cuts had brought the old 7% top rate down step by step. However, on March 30, 2026, Act 110 of 2026, known as H. 4216, replaced that system for tax years beginning after December 31, 2025. According to the South Carolina Department of Revenue, the state now has two graduated rates instead of a single flat rate.
Under the new law, the first $30,000 of taxable income is taxed at 1.99%. Above that level, tax is 5.21% of taxable income, minus $966, which keeps the brackets joined smoothly. In other words, South Carolina tax is graduated, not flat, and the old 6.2% top rate no longer applies for 2026.
The SCIAD: South Carolina’s Own Deduction
Just as importantly, Act 110 changed where the state calculation starts. From 2026, South Carolina starts with federal adjusted gross income, or AGI, rather than federal taxable income. Because of that change, the federal standard and itemised deductions no longer reduce your South Carolina income. Instead, the state created its own deduction, the South Carolina Income Adjusted Deduction, or SCIAD. The SCDOR guidance on H. 4216 confirms these amounts.
Specifically, the SCIAD is $15,000 for single and married filing separately filers, $22,500 for head of household, and $30,000 for married filing jointly and surviving spouse filers. Nevertheless, the full amount only applies at lower incomes. For a single filer, it phases out between $40,000 and $95,000 of AGI. Similarly, the joint amount phases out between $80,000 and $190,000. Other deductions are retained, including the inflation-adjusted dependent exemption, and there is no separate personal exemption.
| Item | 2026 figure |
|---|---|
| South Carolina structure | Two graduated rates, not flat |
| First bracket | 1.99% on taxable income up to $30,000 |
| Top bracket | 5.21% of taxable income, minus $966, at $30,000 or more |
| State starting point | Federal adjusted gross income (AGI) |
| SCIAD — single / married filing separately | Up to $15,000; phases out $40,001–$95,000 AGI |
| SCIAD — head of household | Up to $22,500; phases out $60,001–$142,500 AGI |
| SCIAD — married filing jointly / surviving spouse | Up to $30,000; phases out $80,001–$190,000 AGI |
| Dependent exemption | Retained per eligible dependent, inflation-adjusted |
| Federal standard deduction | $16,100 single / $32,200 joint (federal only) |
| Social Security | 6.2% up to a $184,500 wage base |
| Medicare | 1.45% |
| Minimum wage | No state minimum wage law; federal $7.25 applies |
| Local income taxes | None |
In practice, your employer uses the SC W-4 and the SCDOR withholding tables, which Act 110 directs the SCDOR to adjust for the new system, so payslip withholding may not match your final return exactly.
South Carolina Paycheck Calculator Example: $75,000 Salary
Now, consider a single filer earning $75,000 a year, with no dependents and no pre-tax deductions. First, the federal calculation subtracts the $16,100 standard deduction, leaving federal taxable income of $58,900 and federal income tax of $7,872.00 for 2026. Next, Social Security equals $75,000 × 6.2%, which is $4,650.00, and Medicare equals $75,000 × 1.45%, which is $1,087.50.
Then, the South Carolina calculation starts from AGI of $75,000, not from federal taxable income. Because this filer is single and earns above $40,000, the SCIAD is reduced. The reduction is $15,000 × ($75,000 − $40,000) ÷ $55,000, which equals $9,545.45, rounded down to $9,540. Therefore, the SCIAD is $15,000 − $9,540, which equals $5,460. After that deduction, South Carolina taxable income is $75,000 − $5,460, which equals $69,540.
Finally, apply the top-bracket formula: $69,540 × 5.21% equals $3,623.03, and $3,623.03 − $966 equals $2,657.03 of South Carolina tax. Equivalently, the first $30,000 at 1.99% gives $597.00, and the remaining $39,540 at 5.21% gives $2,060.03, for the same total of $2,657.03.
| Line | Amount |
|---|---|
| Gross pay | $75,000.00 |
| Federal income tax | −$7,872.00 |
| Social Security (6.2%) | −$4,650.00 |
| Medicare (1.45%) | −$1,087.50 |
| South Carolina state tax | −$2,657.03 |
| Net take-home pay | $58,733.47 |
In short, $75,000.00 − $7,872.00 − $4,650.00 − $1,087.50 − $2,657.03 = $58,733.47, so this worker keeps about 78.3% of gross pay. The Georgia paycheck calculator and the North Carolina paycheck calculator show how neighbouring states compare.
Take-Home Pay by Pay Frequency
Your annual net pay stays the same, but pay frequency changes how each deposit feels. Monthly pay gives twelve larger deposits, which can suit rent budgeting. Alternatively, biweekly pay gives twenty-six deposits, so two months contain three paychecks. Weekly pay spreads the same money across fifty-two smaller deposits.
| Pay frequency | Net pay per period |
|---|---|
| Monthly (÷ 12) | $4,894.46 |
| Semi-monthly (÷ 24) | $2,447.23 |
| Biweekly (÷ 26) | $2,258.98 |
| Weekly (÷ 52) | $1,129.49 |
Each figure is the annual net, $58,733.47, divided by the number of periods and rounded to the cent.
Common Deductions Beyond Taxes
Taxes are only part of the story, because most payslips include voluntary deductions too. Health, dental and vision premiums are common, and they are often paid pre-tax, which slightly reduces taxable wages. Similarly, traditional 401(k) contributions lower your current taxable income. By contrast, Roth contributions come out after tax, so they reduce today’s deposit without reducing today’s tax.
Other deductions can include health savings account contributions, union dues and garnishments. Each one lowers your deposit, although it does not change your gross salary. Therefore, compare job offers using both gross and estimated net pay. The Florida paycheck calculator is a useful contrast, because Florida has no state income tax at all.
Simple Ways to Increase Your South Carolina Take-Home Pay
If your net pay feels tight, a few steps can help. First, review your SC W-4 and federal W-4 whenever your family or income changes, because outdated forms often cause over-withholding. Second, consider pre-tax contributions carefully; they reduce taxable income, although they also reduce your immediate deposit.
Additionally, claim every South Carolina deduction you genuinely qualify for, including the dependent exemption and any retirement deductions. However, avoid claiming allowances you cannot support, since that simply creates a bill in April.
Common South Carolina Paycheck Mistakes to Avoid
One frequent mistake is using last year’s rates, because the 2026 reform makes old calculators unreliable. Another mistake is assuming South Carolina now has a flat tax; in reality, the 1.99% and 5.21% rates make it a two-rate graduated system. Likewise, many people still subtract the federal standard deduction from their South Carolina income, even though the SCIAD has replaced it for state purposes.
Workers also forget that South Carolina has no local income taxes, so adding a city tax overstates deductions. Similarly, hourly workers assume a state minimum wage exists, whereas the federal $7.25 rate applies. Finally, remember that the full SCIAD figures are maximums, since higher AGI reduces them.
FAQs
Is South Carolina tax flat or graduated in 2026?
It is graduated, with two rates. The first $30,000 of taxable income is taxed at 1.99%, and income at $30,000 or more is taxed using 5.21% of taxable income, minus $966. It is simpler than before, but it is not a single flat rate.
Is the South Carolina top rate still falling?
Possibly, but not in 2026, when the top rate is 5.21%. From 2027, the top rate can fall in years when the Board of Economic Advisors projects individual income tax revenue growth of at least 5%. Eventually, the law aims for the top rate to reach 1.99%.
Is the South Carolina standard deduction still linked to the federal one?
No, not from 2026. Act 110 decoupled South Carolina from the federal standard and itemised deductions, and the state return now starts with federal AGI. In their place, the SCIAD gives up to $15,000 single, $22,500 head of household and $30,000 joint, subject to phase-outs.
Does South Carolina have a state minimum wage?
No, South Carolina has no state minimum wage law. Therefore, employers covered by the Fair Labor Standards Act must pay at least the federal minimum wage of $7.25 per hour.
Are military and retirement income deductions available in South Carolina?
Yes. Military retirement income can be deducted in full, while other qualifying retirement income can be deducted up to $3,000 before age 65 and up to $10,000 at age 65 or older. In addition, residents aged 65 or older may qualify for a further deduction of up to $15,000, and Social Security benefits are not taxed by South Carolina.
How does the SC W-4 affect my South Carolina paycheck?
Your SC W-4 tells your employer how much South Carolina tax to withhold. You claim allowances on the form, and your employer then uses the SCDOR withholding tables and formula. If your income, filing status or dependents change, a fresh SC W-4 helps keep withholding accurate.
