Power of Attorney

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

To submit a POA:

  1. Obtain and complete a Mississippi Department of Revenue Power of Attorney form
  2. Mail the completed POA form to the Mississippi Department of Revenue at PO Box 1033, Jackson, MS 39215-1033
  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 Mississippi. See Manage Tax Notices for additional details about resolving notice issues.

Issue Action
Filing the wrong form Mississippi has both sales and sellers use tax which are reported separately on different forms. Schedule the return using the correct form for the type of tax that's collected.
Electronic filing credentials are needed or have changed Edit your scheduled returns to add or update your electronic filing credentials.
Filing frequency changed

Mississippi often changes the filing frequency. Pay close attention to information 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.
