Oklahoma Return Mailing Address
When mailing your Oklahoma state tax return, it is important to send it to the correct address. The Oklahoma Tax Commission requires specific forms and documentation to be included with your return, depending on your residency status and filing type.
Required Forms and Documentation
- Nonresidents and Part-Year Residents: File Form 511-NR. Include pages 1-4 only. Do not mail pages 5-7. Include page 8 only if you have an entry on line 36 (Donations from your refund). Attach your W-2s, 1099s, or other withholding statements to substantiate Oklahoma withholding. If you filed a federal return, provide a copy of Form 1040.
- Residents: File Form 511. Ensure all required schedules and supporting documents are included as per the form instructions.
- Additional Forms: If claiming credits or deductions (such as Form 561 for capital gains or Form 564 for aerospace sector employees), include those forms as directed. Do not mail your federal return or withholding statements with Form 511-EF or other state forms unless specifically instructed.
Important Notes
- Do not mail pages 5-7 of Form 511-NR unless specifically required.
- Only include page 8 of Form 511-NR if you are donating a portion of your refund.
- Always include supporting documents such as W-2s and 1099s to verify Oklahoma-source income.
