What if I made a mistake on my tax return?

If you made a mistake on your tax return, don't panic. The Oklahoma Tax Commission provides a solution to rectify the error. Firstly, make sure to file an amended return. Complete Form 511, the Amended Resident Individual Income Tax Return, or Form 561, the Amended Nonresident Fiduciary Income Tax Return. Attach all necessary schedules and documentation to support the changes. Double-check for accuracy before submitting the amended return. If you made an overpayment on your original return, you may request a refund or apply it to future taxes owed. Conversely, if you owe additional taxes, promptly pay the outstanding amount to avoid penalties and interest charges. For further assistance or specific queries, contact the Oklahoma Tax Commission directly.
