Oklahoma FAQ - Where do I send my Oklahoma income tax return?

If you have filed an accepted efiled return, DO NOT mail in anything to the OTC. Retain copies of your forms and all supporting documents for your records.

Paper returns, to replace electronic returns that were rejected by Internal Revenue Service and not resubmitted, are to be mailed to the OTC. The following information is required:

A printout of the return; and
The original, signed, form 511-EF; and
State copies of all W-2's, W-2G's and 1099-R's; and
A cover note giving the date the return was rejected by the Internal Revenue Service, e.g.,rejected 01/30/99.
