Power of Attorney

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

To submit a POA:

  1. Obtain and complete the Washington State Confidential Tax Information Authorization form
  2. Fax the completed form to the Washington State Department of Revenue at (360) 705-6175 or email it to
  3. 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 Washington. See Manage Tax Notices for additional details about resolving notice issues.

Issue Action
Filing frequency changed

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.

Premature notices Washington receives the return much earlier than the payment because the payment is made by ACH. Check MyDOR and see if there's a balance for the period.
