Live in South Carolina, Work in Oklahoma: Which State Taxes Your Paycheck?
Answer
You file twice: Oklahoma first, then South Carolina. There is no reciprocity agreement between these two states, so Oklahoma taxes the income where it was earned and South Carolina taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.

Two states can lawfully tax the same wages: Oklahoma because the work happened there, South Carolina because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the South Carolina return, through the credit for taxes paid to another state.
A South Carolina resident taxed by another state on the same income claims the credit for taxes paid to other states on Form SC1040TC. The credit is capped at the South Carolina 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 · OklahomaForm 511-NR
File the Oklahoma nonresident return FIRST — you need the Oklahoma tax figure before you can complete South Carolina.
- 2Resident return · South CarolinaForm SC1040TC
File a South Carolina resident return reporting all income, then claim the credit for tax paid to Oklahoma. The credit is capped at what South Carolina would have charged on that same income, so if Oklahoma taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in South Carolina and work in Oklahoma. Which state takes the tax out of my paycheck?
You file twice: Oklahoma first, then South Carolina. There is no reciprocity agreement between these two states, so Oklahoma taxes the income where it was earned and South Carolina taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.
Which state should my employer be withholding for?
Oklahoma. The wages are sourced to Oklahoma, so Oklahoma withholding is correct and there is no South Carolina 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. South Carolina gives residents a credit for tax paid to Oklahoma on the same income, claimed on Form SC1040TC. The credit is capped at the South Carolina tax on that income, so if Oklahoma taxes it more heavily the excess is not refunded by either state.
