Multnomah County Business Income Tax (MCBIT)

The Multnomah County Business Income Tax is an income tax on net business income. Revenue generated from the Multnomah County Business Income Tax goes to the County General Fund and is used to finance libraries, law enforcement, community corrections, jails, juvenile justice, bridges, social services, and health services.

You are generally considered to be “doing business” in the City of Portland, Multnomah County, and/or Metro jurisdiction and must register for a Revenue Division tax account if:

• Your business has a retail location in the City of Portland, Multnomah County, and/or Metro jurisdiction.
• Your business comes into the City of Portland, Multnomah County, and/or Metro jurisdiction to perform services.
• Your business maintains a stock of goods in the City of Portland, Multnomah County, and/or Metro jurisdiction.
• Your business owns, leases, or rents personal or real property (including residential or commercial property) in the City of Portland, Multnomah County, and/or Metro jurisdiction.
• You are self-employed and work in Portland and/or Multnomah County

Businesses that are operating within the City of Portland and/or Multnomah County (including rideshare drivers) must register for a Revenue Division tax account within 60 days.

To see if your work location is located within Portland and/or Multnomah County, visit Portland Maps and enter the address of the work location. If you are working within both tax jurisdictions, you are generally subject to both taxes. If you are only doing business in Multnomah County (Gresham, Troutdale, Corbett, etc.) you must still register with the Revenue Division, but you will only be liable for the Multnomah County Business Income Tax.

The Revenue Division will send them a notice requesting them to file a return.If the taxfiler does not file their Combined Tax Return, Civil Penalties will be assessed and collection activities will begin.

Requesting an Extension to File

If a taxfiler cannot complete their business tax return by the original due date, they may request a six-month extension to file their business tax return. This extension should be accompanied by a payment of the estimated tax due, if applicable. This is an extension to file only. There is no extension to pay the business taxes.

Due dates for tax returns and extensions are based on fiscal year end of the taxfiler.

Paying Your Business Taxes

The payment for your businesses taxes is due at the same time you file and pay your federal and state taxes (generally April 15 for most filers). If you have requested an extension of time to file your tax return, your payment is still due on the original due date. There is no extension to pay your business taxes.

Failure to pay the business taxes by the original due date will result in late payment penalties and interest.

Closing your Revenue Division tax account(s)

When a business is sold, closed, or no longer operates within the City of Portland, Multnomah County, and/or Metro’s jurisdiction, they should notify the Revenue Division to close their business tax account(s). When a business tax account is closed, a taxfiler should:

1. File a Combined Tax Return for the final year the business operated in the City, County and/or Metro.
2. Complete the Out of Business form (or a statement with the same information) and attach it to the Combined Tax Return. Make sure to provide:
   • The new owner’s name and address (if the business or property has been sold)
   • Whether you ceased all business activity or only activity in the City of Portland, Multnomah County and/or the Metro jurisdiction

Don’t close the business tax account if:

• There is contract (installment) sales from the sale of the business. This income is considered continuing business income and will require annual filings.
• A taxfiler owns real property and intends to rent or lease it to others.
