Oklahoma Form 511TX 2018

Oklahoma Credit for Tax Paid to Another State

Form 511TX is the form all Oklahoma residents who work in other states will need to file to avoid dual taxation on the income they earned from other states. Dual taxation would occur if these taxpayers did not file Form 511TX because both Oklahoma (the state of residency) and the other state (where the income was earned) would tax the income. Form 511TX prevents dual taxation by issuing an Oklahoma credit for taxpayers who paid taxes on their income to other states. Form 511TX is a supplemental form and should be file with Form 511.
