Oklahoma Unfiled Payroll Tax Returns Checklist
Unfiled payroll tax returns occur when a business or employer has not submitted the required
Oklahoma withholding tax documentation to the state by the filing deadline. Payroll taxes are amounts withheld from employee paychecks and state income taxes collected by employers on behalf of the state.
When these returns remain unfiled, the Oklahoma Tax Commission cannot verify that taxes were properly withheld, reported, or paid. This issue matters because unfiled payroll returns trigger state enforcement actions, penalties, and potential liens against business assets.
What This Issue Means
An unfiled payroll tax return means your business has not submitted the required Form
WTH-10001 (Oklahoma Quarterly Wage Withholding Tax Return) to the Oklahoma Tax
Commission by the state’s deadline. The state cannot determine compliance status, calculate penalties, or establish a payment obligation without a filed return.
Why the State Issued This or Requires This
Oklahoma requires employers to file payroll tax forms to track state income tax withholding and verify remittance. The state uses filed returns to match employer-reported wages with employee tax filings and to ensure proper accounting of withheld funds.
What Happens If This Is Ignored
If payroll tax returns remain unfiled, the Oklahoma Tax Commission typically issues follow-up notices requesting immediate filing and payment. The state will assess estimated tax liability based on available information and issue demands for payment with penalties and interest applied.
What This Does Not Mean
An unfiled payroll tax return notice does not automatically mean the state has filed a lien or taken collection action. This notice represents a filing compliance gap, not yet a final tax bill or judgment.
Checklist: What to Do After Receiving an Unfiled Payroll
Tax Return Notice
Step 1: Locate and Review All Notices From the Oklahoma Tax Commission
Find all written correspondence from the Oklahoma Tax Commission related to unfiled payroll returns. Read each notice to identify the specific tax year and quarter involved, the type of return not filed, any deadline stated for response or filing, and contact information for the assigned representative.

- Compile quarterly payroll reports if your business filed these documents with other
Step 2: Gather Payroll Records and Documentation
Collect all payroll records for the periods referenced in the notice: during the periods in question. employees by pay period. state during the relevant quarters. state authorities. agencies, such as federal or unemployment offices.
Organize records chronologically by tax period. Identify whether payroll returns were filed with the Internal Revenue Service for the same period.
Step 3: Obtain a Copy of Your Current Account Status
Contact the Oklahoma Tax Commission at (405) 521-3160 or toll-free in-state at (800) 522-8165 to request a current account transcript. Request information be mailed to you in writing showing unfiled return periods, any estimated assessments issued, penalties and interest accrued, and the status of any payment arrangements.
Step 4: Prepare the Unfiled Payroll Tax Return
Obtain Form WTH-10001 from the Oklahoma Tax Commission website or by calling the contact numbers listed above. Gather total wages paid to all employees, total Oklahoma income tax withheld, employee names and Social Security numbers, and individual W-2 amounts for each employee. Complete each return according to state instructions and double-check all figures against your payroll records.
Step 5: Calculate Any Additional Taxes, Penalties, and Interest Owed
Using information from Step 3, note the total amount due as stated by the Oklahoma Tax
Commission. A penalty of 10 percent of the tax due is imposed if the failure is not corrected within 15 days after the tax becomes delinquent.
Interest is imposed at 1.25 percent per month. The Oklahoma Tax Commission will not collect the penalty if you remit the tax and interest within 60 days of the mailing of a proposed assessment.
Step 6: Submit the Unfiled Return to the Oklahoma Tax Commission
Send completed payroll tax returns by mail or electronic filing if available. Include a cover letter that states the specific tax year and quarter being reported, your business name, tax ID number, and contact information. Mail to the address provided on the Oklahoma Tax Commission notice or website, and keep a copy of everything you submit.
Step 7: Submit Payment or Request a Payment Arrangement
Determine the total amount due, including principal, penalties, and interest. Make full payment if possible, or contact the Oklahoma Tax Commission to request a payment plan by calling (405)
521-3160 or toll-free in-state at (800) 522-8165.

- Payroll tax debt review and resolution
- Penalty and interest reduction options
- Payment plans and compliance solutions
- Representation before state tax agencies
Step 8: Follow Up After Submission
Wait 15 to 30 days after submitting the return and payment or payment plan request. Contact the Oklahoma Tax Commission to confirm receipt of your filing and payment and request written confirmation that the return has been processed.
What Happens After This Is Completed
After you file the unfiled payroll return and make payment or establish a payment plan, the
Oklahoma Tax Commission will process the filing and update your account status. The state typically issues written confirmation that the return has been received and recorded.
Common Mistakes to Avoid
Missing the deadline on a follow-up notice can result in additional penalties or enforcement action. Submitting incomplete or inaccurate returns may cause rejection and require resubmission, delaying resolution.
Failing to keep proof of submission can leave you without evidence that you met your obligation.
Not following a payment plan agreement can invalidate the arrangement and trigger collection action.
If you no longer have wages or employees, you must either file a quarterly zero return or close the account. Even if wages paid were not sufficient to require withholding, a report must be filed with zero amounts entered.
Frequently Asked Questions
What is the difference between an unfiled return and an underpaid return?
An unfiled return means Form WTH-10001 was never submitted to the state. An underpaid return means the form was filed, but the amount of tax paid was less than the amount owed.
Can I file an unfiled payroll tax return after many years have passed?
Yes. The state can assess and collect on unfiled returns indefinitely, though penalties and interest will have accrued. Contact the Oklahoma Tax Commission to determine what is owed for each period involved.
Will filing the unfiled return eliminate penalties?
Filing alone does not eliminate penalties. The Oklahoma Tax Commission may waive penalties if you remit tax and interest within 60 days of a proposed assessment or if you can demonstrate reasonable cause.
Next Steps
Receiving notice of an unfiled payroll tax return is stressful, but it is a solvable administrative issue. The process involves filing the missing Form WTH-10001, calculating what is owed, and making arrangements to pay.
