File your business tax returns

Service
Businesses subject to the Portland Business License Tax, Multnomah County Business Income Tax, and/or Clean Energy Surcharge must file a business tax return at the same time they file their federal and state income tax returns. You must claim an exemption from the business tax on the tax return.

Filing your business tax return(s) should take 30-45 minutes to complete. This time can be reduced if you have all your federal and state tax information available.

File your business tax return(s)

You will need a Portland Revenue Online account to file your business tax return(s) online. You will be asked to log in or create an account.

If you need additional time to file your business tax return(s), you must submit a Request for an Extension of Time to File by the original due date of your return, unless you have filed a timely extension to file with the IRS. This is only an extension of time to file your return.

All taxes must still be paid by the original due date of the return.
