1. City of Portland Business License Tax Registration (Revenue Division)

   Portland has no flat-fee general business license. All businesses operating in Portland - including sole proprietors and home-based businesses - must register for the City of Portland Business License Tax with the Revenue Division within 60 days of starting business. Registration is free. The tax is 2.6% of net business income with a $100 minimum, filed annually on a combined return with the Multnomah County Business Income Tax (2% of net income; gross receipts under $100,000 are exempt from the county tax). Businesses with gross receipts under $75,000 (tax years beginning in 2026; rising to $100,000 in 2027) are exempt from the city tax but must still register. The Metro Supportive Housing Services 1% business income tax applies only to businesses with gross receipts over $5 million.

2. Portland / Multnomah County - Building Permit & Certificate of Occupancy (fitness studio)

   If you are building out, renovating, or changing the use/occupancy classification of a commercial space for your fitness studio, you need building permits from Portland Permitting & Development (PPD, formerly BDS) - even where no alterations are planned, a change-of-occupancy permit documents the new use. Electrical, plumbing, and fire/life-safety inspections apply to the permitted work. A space already approved for the same use needs no new Certificate of Occupancy.
