5.5% Effective (Top 6.4%)
Statutory bracket

The state has a year-end individual income tax rebate funded by a recurring budget surplus, which is unusual among states.

Local taxes: South Carolina has no local income tax, so the state rate applies uniformly to a Charleston or Columbia contractor.

State revenue agency: South Carolina Department of Revenue.South Carolina has no quarterly estimated income tax voucher requirement for individuals. Payment is made with the annual South Carolina Individual Income Tax Return via the South Carolina Department of Revenue.

Tax Strategy for rideshare drivers

You may deduct the standard mileage rate or your actual vehicle expenses, but not both, and switching methods year to year is allowed. Model both before filing: actual expenses win quickly at high mileage with a financed vehicle, while the standard rate wins for a leased or paid-off car. Rideshare-specific items such as cleaning, amenities, and dash cameras stack on top of whichever vehicle method you use.

Why income swings matter:

Surge pricing and airport runs can double a normal week. If a large bonus payout lands in one quarter, that quarter's voucher will look far out of line; use the annual figure divided by four so the other three quarters are not left underpaid and exposed to the underpayment penalty.

IRS safe harbour:

To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

How much should a rideshare driver set aside for quarterly taxes in South Carolina?

Set aside about 18.2% of everything you bill — 18.2% of $52,000 in gross income is $9,456 a year, or $2,364 per quarter. That total covers self-employment tax (15.3% on 92.35% of net profit), federal income tax on the remainder after your standard deduction, and South Carolina adds roughly 5.5% on your taxable South Carolina income. The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.

IRS Form 1040-ES estimated payments for 2026 are due April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15, 2027 (Q4). South Carolina has no quarterly estimated income tax voucher requirement for individuals.

What expenses can a rideshare driver write off in South Carolina?

Common write-offs for rideshare drivers include business mileage log, vehicle sanitizing & car washes, passenger perks & amenities, smartphone & data plan, dash cam & safety equipment. Because South Carolina taxes self-employment income at 5.5%, each deduction reduces both your federal and your South Carolina liability, so a deduction is worth more than its face value.
