The right reserve percentage for South Carolina
South Carolina uses graduated brackets topping out near 6.2%, layered on top of federal income tax and the 15.3% self-employment tax. That is why the blanket "save 30%" advice misses here: South Carolina filers typically need 30-35% of net profit, not a round number borrowed from someone in another state.
South Carolina's top rate is around 6.2% and continues to step down.
The mechanic matters more than the number. Tax trouble is a cash failure, not a math failure — money arrives, looks like income, and gets spent. Moving the reserve out the day each deposit lands is what keeps the South Carolina and federal bills funded.

Should I save a percentage of gross or net in South Carolina?
Tax is owed on net profit, but the practical move is a fixed percentage of every deposit the day it lands. The calculator converts your South Carolina tax bill into a percentage of gross so the transfer can be automatic.
What are the quarterly deadlines in South Carolina?
Federal estimates are due around April 15, June 15, September 15 and January 15, and South Carolina runs a state estimate schedule on roughly the same dates.
Are there local taxes to reserve for in South Carolina?
South Carolina does not add a broad local income tax on self-employment earnings, so your reserve only needs to cover state and federal.
What if I under-reserve in South Carolina?
You still owe the tax, plus a federal underpayment penalty if you owed $1,000 or more without making estimates, and South Carolina charges its own interest on late state estimates. The penalty accrues like interest, so it grows until paid.
