Error Code: R0000-901-01
Error Message:
Filer’s EIN and Name Control in the Return Header must match data in the e-File database.
Understanding the Error:
You’ve encountered error R0000-901-01 while e-filing your tax return. This error indicates a discrepancy between the information on your return and the data stored in the IRS e-file database. Specifically, the Employer Identification Number (EIN) and Name Control, a four-character code derived from the business name, don’t match.
Common Causes:
- Incorrect EIN or Name Control: Double-check these values for accuracy on your return and in the IRS database.
- Name Change: If your business name has changed, ensure you’re using the correct Name.
- Prior Year Name Control: In some cases, the IRS might use a different Name Control than what we’ve calculated. We are calculating the name control using the Business Type you choose while adding the Filer Profile.
Steps to Resolve:
- Verify EIN and Name Control:
- Carefully review your tax return and compare the EIN and Name Control with those on your business records and any previous tax filings.
- Address any inconsistencies found.
- Check Name Change or Address Change Boxes:
- If applicable, ensure these boxes are accurately checked on your return.
- Contact the IRS:
- If the issue persists, reach out to the IRS e-help Desk at 866-255-0654. They can verify your EIN and guide correcting any discrepancies.
- Enter the correct information and Retransmit:
- If you’ve made any corrections to the EIN or Name Control, retransmit it.
- Please note that the retransmission is FREE with TaxZerone.
Here’s how you correct the mismatch in Name Control
- Check the EIN and Name of the organization with the Determination letter.
- If the organization changed its official name and notified the changes to IRS, then check the “Name change” checkbox in return.
- Review the details, and click the Transmit button to re-transmit your return to the IRS at ZERO additional cost.
