Get the info you need to manage notices for Oklahoma, including submitting a power of attorney and understanding common issues.

Power of Attorney

Oklahoma requires a Power of Attorney (POA) for Avalara to resolve notices for you.

To submit a POA:

  1. Obtain and complete an Oklahoma BT-129 Power of Attorney form
  2. Send the completed POA form and notice to us by submitting a case. Processing takes about 6 - 8 weeks.

After we have a POA on file, you don't have to submit another one unless something has changed.

Common Issues

These are the most common notice issues to resolve for Oklahoma. See Manage Tax Notices for additional details about resolving notice issues.

Issue Action
Filing frequency changed

Oklahoma sends out frequency change notifications by mail. Pay close attention to mail received from the Department of Revenue. Send notification of filing frequency changes to us by submitting a case immediately. Edit your scheduled returns to change the filing frequency.

Prepayments are required, but weren't remitted

Be aware if you're required to make prepayments to Oklahoma. 

Tax type mismatch

Make sure you've provided the correct Oklahoma tax ID based on the way your business is registered and the tax return you need to file.
