The rules
South Carolina self-employment & S-corp rules
- State income tax: up to 6%. Self-employment tax itself (15.3%) is federal and identical in every state.
- Minimum franchise / LLC fee: $0/year for an LLC or S-corp in South Carolina, regardless of income.
- PTET (SALT-cap workaround): Available — the pass-through entity tax election lets the business deduct state tax federally, bypassing the SALT cap on that income (the $40,400 2026 cap phases down toward $10,000 above $505,000 of MAGI, where PTET helps most).
Questions
Frequently asked questions
How much self-employment tax will I pay in South Carolina?▾
Self-employment tax is federal — 15.3% (12.4% Social Security up to the $184,500 wage base + 2.9% Medicare) on 92.35% of your net self-employment income, the same in South Carolina as everywhere. South Carolina then taxes that same income at its state income-tax rate (up to 6%). The calculator above shows your SE tax at any income.
Is an S-corp worth it for a South Carolina freelancer or LLC owner?▾
In South Carolina, electing S-corp status generally starts saving money once net self-employment income is around $52,000. Below that, the payroll/admin cost outweighs the self-employment-tax savings.
Does South Carolina have a PTET (SALT-cap workaround)?▾
Yes. South Carolina offers a pass-through entity tax (PTET) election that lets the business pay state income tax and deduct it federally, bypassing the federal SALT cap on that income. The cap is $40,400 for 2026 but phases down toward $10,000 above ~$505,000 of MAGI, so PTET matters most for higher earners. If you elect S-corp, this often stacks on top of the SE-tax savings.
How is my "reasonable salary" set for an S-corp?▾
The IRS requires S-corp owner-employees to pay themselves a reasonable salary (subject to FICA) before taking distributions. This calculator assumes 60% salary / 40% distributions as an illustration — your actual reasonable compensation depends on your role and industry and should be set with a CPA.
