Power of Attorney

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

Don't send a Power of Attorney to the Department of Revenue Services unless you've been in contact with them and determined that you want a third party to represent your interests.

To submit a POA:

  1. Obtain and complete a Connecticut LGL-001 Power of Attorney form
  2. Mail, fax, or deliver the form directly to the DRS employee or unit with whom Avalara will interact. If you're not sure, contact a DRS representative to find out the name and address or fax number where the LGL-001 should be sent. Call 860-297-5962 to contact the Connecticut DRS.
  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

This is the most common notice issue to resolve for Connecticut. See Manage Tax Notices for additional details about resolving notice issues.

Issue Action
Filing frequency changed

Filing frequency changes are a common issue. Connecticut sends out filing 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.
