Live in Oklahoma, Work in South Carolina: Which State Taxes Your Paycheck?
Answer
Expect withholding in South Carolina and a return in both. Oklahoma and South Carolina hold no reciprocal agreement, so the overlap is resolved after the fact: South Carolina taxes the South Carolina-source wages, and your Oklahoma resident return claims a credit for that tax against the Oklahoma liability on the same income.

Two states can lawfully tax the same wages: South Carolina because the work happened there, Oklahoma because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Oklahoma return, through the credit for taxes paid to another state.
A Oklahoma resident taxed by another state on the same income claims the credit for taxes paid to other states on Form 511-TX. The credit is capped at the Oklahoma tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
What you file
- 1Nonresident return · South CarolinaForm SC1040 with Schedule NR
File the South Carolina nonresident return FIRST — you need the South Carolina tax figure before you can complete Oklahoma.
- 2Resident return · OklahomaForm 511-TX
File a Oklahoma resident return reporting all income, then claim the credit for tax paid to South Carolina. The credit is capped at what Oklahoma would have charged on that same income, so if South Carolina taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Oklahoma and work in South Carolina. Which state takes the tax out of my paycheck?
Expect withholding in South Carolina and a return in both. Oklahoma and South Carolina hold no reciprocal agreement, so the overlap is resolved after the fact: South Carolina taxes the South Carolina-source wages, and your Oklahoma resident return claims a credit for that tax against the Oklahoma liability on the same income.
Which state should my employer be withholding for?
South Carolina. The wages are sourced to South Carolina, so South Carolina withholding is correct and there is no Oklahoma withholding to set up.
Will I end up paying tax twice on the same income?
Not twice over, but you will pay the higher of the two rates. Oklahoma gives residents a credit for tax paid to South Carolina on the same income, claimed on Form 511-TX. The credit is capped at the Oklahoma tax on that income, so if South Carolina taxes it more heavily the excess is not refunded by either state.
