Gig Worker Tax Calculator — South Carolina (2026)
Driving for Uber, Lyft, DoorDash, Instacart or Amazon Flex in South Carolina makes you an independent contractor, not an employee. No tax is withheld from your payouts, so the whole bill — 15.3% self-employment tax, federal income tax and South Carolina income tax — arrives at once unless you pay quarterly. Enter your net earnings after mileage to see the damage. South Carolina uses a progressive income tax with 3 brackets running from 0.00% up to 6.20%, applied after a state standard deduction of $16,100.

Gross 1099 income minus business expenses.
Mileage is the biggest deduction for Charleston drivers
At the 2026 standard mileage rate of $0.67 per business mile, a rideshare driver logging 25,000 miles deducts $16,750 before any tax applies. In dense Charleston traffic, deadhead miles between orders count too — as long as you are logged into the app and available.
Track miles per platform with a mileage app. Uber and DoorDash only report on-trip miles, which typically understates your true deductible mileage by 20–40%.
Platform 1099s and South Carolina thresholds
Rideshare companies issue 1099-K for passenger fares and 1099-NEC for bonuses and referrals; delivery apps usually issue 1099-NEC above $600. You owe tax on all net earnings whether or not a form arrives.
South Carolina taxes gig profit like any other income at 0.00%–6.20%, so a $30,000 net-profit year adds about $250 in state tax.
South Carolina has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Gig economics in South Carolina
With South Carolina leaning on automotive, aerospace, and tourism, demand patterns differ from national averages: airport and event surges dominate in Charleston, and fuel plus insurance costs eat directly into net profit before tax.
A realistic full-time gig year of $45,000 in net profit produces roughly $10,133 of total tax in South Carolina, or about $2,533 per quarterly payment.
Local and payroll taxes South Carolina adds on top
South Carolina adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
South Carolina has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Nobody withholds these for you when you are self-employed in South Carolina. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from South Carolina
South Carolina has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Charleston resident spending part of the year at a client site in North Carolina may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your South Carolina tax bill
South Carolina charges a 6% state sales tax, homeowners pay an average effective property tax of 0.57% of market value, and the minimum wage in force during 2026 is $7.25 an hour.
Local option taxes bring most areas to 7%–9%.
Income tax is only one part of a state's take. South Carolina recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. South Carolina exempts Social Security and offers a $10,000 retirement deduction plus a $15,000 senior deduction at 65+.
