General Business License
Oregon does not have a statewide general business license and notably has no sales tax, significantly simplifying business registration. Businesses must register their entity with the Oregon Secretary of State and register with the Oregon Department of Revenue for income tax purposes. Some Oregon cities require local business licenses — Portland has an extensive business licensing system through the Business License System, and many other cities have their own requirements. Multnomah County requires additional business registration.

Home-Based Business Rules
Oregon municipalities regulate home-based businesses through local zoning ordinances within the statewide planning framework. Portland allows home occupations in residential zones with restrictions on customer visits, delivery frequency, and commercial vehicle storage. Oregon's urban growth boundary system means home-based businesses are common and generally supported given the high cost of commercial space. Oregon's cottage food law supports home-based food production and direct consumer sales up to $50,000 annually.
