Instructions for completing the Combined Excise Tax Return

Did you know you can register and file your return electronically, even if you have "No Business Activity" to report?

Note: All taxpayers are required to file and pay electronically. See our Mandatory electronic filing page for more information.

Getting Started

When is my tax return due?

Click on your assigned filing frequency for due date information:

If the due date falls on a weekend or legal holiday the due date is the following business day.

Are you filing an amended return?

If so, check the box located on page one of your return. An amended tax return is submitted to show corrections to the originally filed excise tax return.

Learn more about amending your tax return.

Name and business Name

Write your name and business name as it appears on your business registration.

Account ID

Write your account ID here. The account ID, also called Uniform Business Identifier (UBI), is a nine-digit number that appears on your business registration. You might see an extra digit after the first nine (e.g., 600 123 456 8). Only enter the first nine digits. Please include your account ID on all correspondence, including checks.


Write your mailing address.

Note: This is the address all correspondence will be mailed to. This includes tax returns, refunds, and other notices. If this is a new address, please also check the box below the address block.

Has your address changed?

  • If you had a change of mailing address only, check the mailing address box and make the necessary changes to the preprinted address label.
  • If you added or changed a business location, check the business location box and write in your new location in the blank area.

Closing your business?

Check the Business Closed box and write the date your business closed.

Learn more about closing your account.

Other correspondence?

Check the box and enclose with your return.

No business activity?

If you had no business activity, check the box, on page one, located above the address block. Sign and date the return in the space provided.

You may also report no business activity online or by phone.
