South Carolina Paycheck Calculator (Hourly)

How the South Carolina Paycheck Calculator Works

This South Carolina paycheck calculator hourly tool computes your take-home pay by subtracting federal income tax, South Carolina state income tax using the progressive bracket system, and FICA (Social Security and Medicare) from your gross earnings. South Carolina's three-bracket progressive structure means your effective state tax rate depends on how much of your income falls into each bracket, making the calculation more nuanced than a flat-tax state like North Carolina.

The core formula:

Take-Home = Gross Pay - Federal Tax - South Carolina State Tax - Social Security - Medicare $$P_{\text{net}}=P_{\text{gross}}-T_{\text{fed}}-T_{\text{SC}}-T_{\text{SS}}-T_{\text{Med}}$$

Annual gross pay equals your hourly wage multiplied by hours per week multiplied by 52 weeks. To convert your hourly rate to an annualized figure or vice versa, use our salary calculator. Federal income tax is calculated using the 2026 IRS brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) applied progressively to your taxable income, which is gross pay minus the federal standard deduction ($15,000 single, $30,000 married, $22,500 head of household) and any pre-tax retirement contributions. South Carolina state tax is computed by applying the three progressive brackets to your taxable income after subtracting the South Carolina standard deduction (which matches the federal amounts: $15,000 single, $30,000 married, $22,500 head of household). The first $3,460 is exempt, the next $13,870 (from $3,460 to $17,330) is taxed at 3%, and everything above $17,330 is taxed at 6.4%. Social Security applies a flat 6.2% on wages up to $176,100, and Medicare applies 1.45% on all wages with an extra 0.9% surcharge above $200,000 single or $250,000 married.

South Carolina Hourly Paycheck Tax Breakdown

South Carolina's income tax structure underwent a major simplification in recent years, consolidating from a six-bracket system into the current three-bracket framework with rates of 0%, 3%, and 6.4%. The state legislature has enacted a phased plan to reduce the top rate toward 3.99% by 2027, which would bring South Carolina into competitive alignment with its neighbors. This reform reflects the Palmetto State's broader strategy to attract businesses and workers from higher-tax states, building on the success of economic development anchors like the Boeing 787 Dreamliner assembly plant in North Charleston, the BMW manufacturing facility in Spartanburg (the company's largest plant worldwide by production volume), and the Volvo Cars plant in Berkeley County.

Under the current structure, a worker earning $40,000 in South Carolina taxable income would owe: $0 on the first $3,460, $416.10 on the next $13,870 (at 3%), and $1,450.88 on the remaining $22,670 (at 6.4%), for a total state tax of $1,866.98 and an effective rate of about 4.67%. By contrast, the same $40,000 in taxable income in North Carolina at a flat 4.5% would result in $1,800 in state tax, making North Carolina slightly cheaper for this income level. In Georgia at a flat 5.39%, the same taxable income would generate $2,156 in state tax, making Georgia the most expensive of the three for this particular scenario.

South Carolina's generous standard deduction, which matches the federal amounts, provides meaningful relief at lower income levels. A single filer earning $30,000 gross has only $15,000 in SC taxable income after the $15,000 standard deduction, resulting in a state tax of just $271.88 (an effective rate of 0.91% on gross income). This low effective rate at modest incomes is particularly important for the state's large hospitality and service workforce in tourist destinations like Charleston, Hilton Head Island, and Myrtle Beach.

Your South Carolina paycheck deductions come from four sources:

• Federal income tax: Progressive brackets based on filing status; see our income tax calculator for a full federal estimate.
• South Carolina state income tax: Progressive brackets of 0% (first $3,460), 3% ($3,460-$17,330), and 6.4% (above $17,330) on taxable income (gross minus SC standard deduction of $15,000 single, $30,000 married, $22,500 head of household).
• Social Security: 6.2% on wages up to $176,100.
• Medicare: 1.45% on all wages, plus 0.9% surtax above $200,000 single or $250,000 married.

Variable Definitions

Hourly Wage: Your gross pay per hour before deductions. South Carolina's economy encompasses a wide range of hourly pay rates across its key industries. At the Boeing assembly facility in North Charleston, production technicians earn $22 to $35 per hour, while engineers earn $40 to $65 per hour. At the BMW plant in Spartanburg, which produces X-model SUVs for global export through the Port of Charleston, manufacturing associates earn $20 to $28 per hour. In the tourism sector centered on Charleston's historic district, Myrtle Beach's Grand Strand, and Hilton Head Island, hospitality workers earn $12 to $18 per hour plus tips for tipped positions. Military personnel at Fort Jackson (the Army's largest basic training installation), Shaw Air Force Base in Sumter, and the Marine Corps Recruit Depot at Parris Island earn according to federal pay scales but are subject to South Carolina tax on non-military income if they claim SC residency.

Hours per Week: Total weekly hours, typically 40 for full-time. South Carolina follows federal Fair Labor Standards Act overtime rules requiring 1.5x pay for hours above 40 per week for non-exempt workers. The state has no daily overtime requirement. Manufacturing workers in the Upstate automotive corridor (Spartanburg, Greenville, Anderson) and at tire plants like Michelin's North American headquarters in Greenville frequently log overtime during peak production periods, which pushes their annualized earnings higher and may shift more income into the 6.4% state bracket.

Pay Frequency: How often you receive a paycheck. Weekly = 52 paychecks, biweekly = 26, semi-monthly = 24, monthly = 12. Annual totals do not change with frequency, but per-period amounts do. Most South Carolina employers, including Boeing, BMW, Prisma Health (the state's largest private employer), and the Medical University of South Carolina, pay biweekly.

Filing Status: Determines both federal and South Carolina standard deductions and the federal bracket thresholds. Single uses South Carolina's $15,000 standard deduction; married filing jointly uses $30,000; head of household uses $22,500. Because South Carolina's standard deduction matches the federal amount, your state and federal taxable income starting points are identical, unlike in states such as North Carolina where the state deduction is lower than federal.

Pre-Tax Deduction: Percentage of gross pay contributed to 401(k), 403(b), HSA, or similar pre-tax accounts. These reduce both federal and South Carolina taxable income. A worker earning $60,000 who contributes 6% ($3,600) saves approximately $230 in South Carolina state tax (at the 6.4% marginal rate) and $432 in federal tax in the 12% bracket, for total tax-deferred savings of $662 on the contribution.

Worked Example 1: South Carolina Hourly Paycheck at $18/Hour

A single filer earning $18/hour, working 40 hours/week, biweekly pay, with a 3% pre-tax 401(k) contribution. This profile fits a production associate at one of the Upstate manufacturing plants, a tourism-sector worker in Myrtle Beach or Charleston, or a starting administrative role at Fort Jackson:

1. Annual gross: $18 x 40 x 52 = $37,440
2. Pre-tax 401(k): $37,440 x 3% = $1,123.20
3. Taxable gross: $37,440 - $1,123.20 = $36,316.80
4. Federal taxable income: $36,316.80 - $15,000 (standard deduction) = $21,316.80
5. Federal tax: ($11,925 x 10%) + ($9,391.80 x 12%) = $1,192.50 + $1,127.02 = $2,319.52
6. SC taxable income: $36,316.80 - $15,000 (SC standard deduction) = $21,316.80
7. SC state tax: ($3,460 x 0%) + ($13,870 x 3%) + ($3,986.80 x 6.4%) = $0 + $416.10 + $255.16 = $671.26
8. Social Security: $36,316.80 x 6.2% = $2,251.64
9. Medicare: $36,316.80 x 1.45% = $526.59
10. Total deductions: $1,123.20 + $2,319.52 + $671.26 + $2,251.64 + $526.59 = $6,892.21
11. Annual take-home: $37,440 - $6,892.21 = $30,547.79
12. Biweekly take-home: $30,547.79 / 26 = $1,174.92

Worked Example 2: South Carolina Hourly Paycheck at $48/Hour

A married filing jointly worker earning $48/hour, working 40 hours/week, biweekly pay, with a 10% pre-tax 401(k) contribution. This represents a senior engineer at Boeing's North Charleston facility, an experienced IT professional in the growing Greenville tech corridor, or a nurse practitioner at the Medical University of South Carolina in Charleston:

1. Annual gross: $48 x 40 x 52 = $99,840
2. Pre-tax 401(k): $99,840 x 10% = $9,984
3. Taxable gross: $99,840 - $9,984 = $89,856
4. Federal taxable income: $89,856 - $30,000 (married standard deduction) = $59,856
5. Federal tax: ($23,850 x 10%) + ($36,006 x 12%) = $2,385 + $4,320.72 = $6,705.72
6. SC taxable income: $89,856 - $30,000 (SC married standard deduction) = $59,856
7. SC state tax: ($3,460 x 0%) + ($13,870 x 3%) + ($42,526 x 6.4%) = $0 + $416.10 + $2,721.66 = $3,137.76
8. Social Security: $89,856 x 6.2% = $5,571.07
9. Medicare: $89,856 x 1.45% = $1,302.91
10. Total deductions: $9,984 + $6,705.72 + $3,137.76 + $5,571.07 + $1,302.91 = $26,701.46
11. Annual take-home: $99,840 - $26,701.46 = $73,138.54
12. Biweekly take-home: $73,138.54 / 26 = $2,813.02

This couple keeps about 73.3% of gross pay after all federal, state, and FICA taxes plus their 401(k) contribution. The South Carolina portion accounts for 3.14% of gross income, demonstrating how the progressive bracket system combined with the generous $30,000 married standard deduction produces a lower effective state rate than the statutory top rate of 6.4%. The 10% 401(k) contribution alone saves them about $639 in South Carolina state tax and $1,198 in federal tax annually.

Edge Cases and Advanced Scenarios

Military pay and South Carolina taxes: South Carolina has a substantial military presence, including Fort Jackson in Columbia (the Army's largest basic training installation, processing over 50,000 soldiers annually), Shaw Air Force Base near Sumter, Parris Island Marine Corps Recruit Depot, Joint Base Charleston, and the Marine Corps Air Station in Beaufort. Under the Servicemembers Civil Relief Act, active-duty military members who maintain legal residency in another state do not owe South Carolina income tax on their military pay, even if stationed in the state for years. South Carolina also provides a full exemption for military retirement pay, making it one of the most military-friendly states for retirees. However, military spouses working civilian jobs in South Carolina may owe state tax unless they qualify for the Military Spouses Residency Relief Act, which allows spouses to maintain their servicemember's state of legal residence for tax purposes.

Remote workers and multi-state sourcing: South Carolina taxes residents on all income regardless of where it is earned. A Charleston resident working remotely for a company headquartered in New York owes the full South Carolina progressive tax on those wages. Conversely, a nonresident who works entirely from another state for a South Carolina employer generally does not owe South Carolina income tax because the work is not performed within the state. This has become an increasingly important distinction as the Charleston and Greenville tech sectors have grown rapidly, with companies like Blackbaud (headquartered in Charleston), BenefitFocus, and numerous startups employing both local and remote workers. Workers who split time between South Carolina and another state must apportion income based on days physically worked in each state.

The Social Security wage base cap and high earners: If you earn above $176,100 annually, no additional Social Security tax is withheld on wages exceeding that threshold. For a senior Boeing engineer in North Charleston earning $200,000, Social Security caps at $176,100 x 6.2% = $10,918.20, saving about $1,481.58 compared to applying the 6.2% rate to all wages. However, the additional Medicare surtax of 0.9% kicks in on wages above $200,000 for single filers or $250,000 for married filing jointly. Workers in the growing Greenville-Spartanburg financial and tech sectors, where six-figure salaries are increasingly common, should factor in this surtax threshold when evaluating take-home pay projections using our federal income tax percentage calculator.

South Carolina's rate reduction trajectory and planning implications: With the top rate scheduled to decline from 6.4% toward 3.99% by 2027, South Carolina workers should consider the timing implications for deferred compensation, stock option exercises, and bonus payments. If you have the ability to time when income is recognized, deferring income to a year when the lower rate is in effect could yield meaningful savings. For example, on $50,000 of income taxed at the top bracket, the difference between 6.4% and 3.99% is $1,205 per year. Workers evaluating long-term job offers in South Carolina should also weigh the trajectory favorably: by 2027, a South Carolina worker may pay less in state income tax than a comparable worker in North Carolina at 4.5% or Georgia at 5.39%, reversing the current competitive disadvantage.

What to Do with Your South Carolina Paycheck Result

• Compare your calculated take-home pay to your actual paycheck stub. Discrepancies often come from employer-sponsored benefits like health insurance, dental, vision, or commuter benefits that this calculator does not include.
• If you are considering a move between South Carolina and a neighboring state, multiply the state tax difference by the number of years you expect to live in the new state. Moving from South Carolina to North Carolina could save roughly 1-2% of taxable income per year at higher incomes under current rates, though this gap is closing as South Carolina's rate drops.
• Maximize your 401(k) contribution to reduce both federal and South Carolina tax. Every $1,000 in pre-tax contributions saves up to $64 in South Carolina state tax at the top bracket plus your federal marginal rate savings.
• Use our federal income tax percentage calculator to check your effective federal rate and compare it to South Carolina's effective state rate. Most South Carolina workers find their effective state rate falls in the 1.5% to 5.0% range after the standard deduction.
