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

Two states can lawfully tax the same wages: Oklahoma because the work happened there, Connecticut because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Connecticut return, through the credit for taxes paid to another state.
A Connecticut resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule 2 (Form CT-1040). The credit is capped at the Connecticut 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 Connecticut.
- 2Resident return · ConnecticutSchedule 2 (Form CT-1040)
File a Connecticut resident return reporting all income, then claim the credit for tax paid to Oklahoma. The credit is capped at what Connecticut would have charged on that same income, so if Oklahoma taxes it at a higher rate the difference is not refunded.

The other direction
Reversing the commute does not always reverse the answer. Living in Oklahoma and working in Connecticut gives:Both states — credit offsets the double tax.
Same two states, different situation
The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.
- Remote worker: Connecticut → OklahomaHome state only
- 1099 contractor: Connecticut → OklahomaHome state, plus the client state if you work there
- Moved mid-year: Connecticut → OklahomaTwo part-year returns

Questions people actually ask
I live in Connecticut and work in Oklahoma. Which state takes the tax out of my paycheck?
Expect withholding in Oklahoma and a return in both. Connecticut and Oklahoma hold no reciprocal agreement, so the overlap is resolved after the fact: Oklahoma taxes the Oklahoma-source wages, and your Connecticut resident return claims a credit for that tax against the Connecticut liability on the same income.
Which state should my employer be withholding for?
Oklahoma. The wages are sourced to Oklahoma, so Oklahoma withholding is correct and there is no Connecticut 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. Connecticut gives residents a credit for tax paid to Oklahoma on the same income, claimed on Schedule 2 (Form CT-1040). The credit is capped at the Connecticut tax on that income, so if Oklahoma taxes it more heavily the excess is not refunded by either state.
