Form 511V: Oklahoma Individual Income Tax Payment Voucher

Form 511V, also known as the Oklahoma Individual Income Tax Payment Voucher, is a document used by the Oklahoma Tax Commission (OTC) to help them process your individual income tax payment efficiently. It's essentially a detachable slip attached to your tax return (Form 511 or 511NR) that you can use to include your Social Security number and other relevant information alongside your check or money order.

Who Should Use Form 511V?

While using Form 511V isn't mandatory, it's highly recommended for individuals who:

A. Filed a paper tax return: If you opted for the traditional paper method to file your Oklahoma income tax return (Form 511 or 511NR), using the 511V voucher simplifies the payment process by keeping your tax return and payment together.

B. Have a balance due: This voucher is particularly helpful if you owe any tax after filing your return. Including the completed 511V with your check or money order ensures your payment is accurately linked to your specific tax return.

Is using Form 511V mandatory?
