RSU Tax Calculator for South Carolina

RSU vesting in South Carolina triggers up to 6.4% state income tax, treated as ordinary income just like your salary. Your employer typically sells shares at vesting to cover the combined federal, state, and FICA withholding, which can consume 35-50% of the vested shares depending on your income level. This calculator shows you exactly how many shares (or dollars) you keep after all South Carolina tax layers are applied.

South Carolina uses a graduated income tax with brackets ranging from 0-6.4%. Lower income is taxed at lower rates, with the 6.4% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. South Carolina does not have local income taxes, so the state graduated rate is the total state-level income tax burden.

The table below shows what you actually keep at five salary levels in South Carolina, accounting for federal tax, FICA, and South Carolina's graduated (0-6.4%) state tax.
