File your business tax return

All businesses must file a Combined Tax Return at the same time the business files their Federal & State tax returns.

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

  1. Download and fill out your Combined Tax Return

    To file your Combined Tax Return or request an extension to file, you must first register your business with the City of Portland.

    If your business income is reported on a Schedule C, E, and/or F with your federal Form 1040, you should file Form SP-2020.

    If your business income is reported on federal Form 1065, you should file Form P-2020.

    If your business income is reported on federal Form 1120-S, you should file Form SC-2020.

    If your business income is reported on federal Form 1120, you should file Form C-2020.

    If your business income is reported on a Schedule C, E, and/or F with your federal Form 1041, you should file Form E-2020.

    If you need additional time to file your Combined Tax Return, you should file a Request for Extension (Form EXT) by the original due date of your return, unless you have filed a timely extension to file with the IRS. This grants an additional six months to file your Combined Tax Return. You must still pay all tax due by the original due date.

  2. Mail the completed form with supporting tax pages and any payment to us

    • Write only one check for any amount due and make it payable to 'City of Portland Revenue Division.'
