Choosing between an LLC and an S Corp in Oregon is one of the most consequential tax decisions a small business owner can make – and the right answer depends entirely on your profit level. LLCs offer simplicity and flexibility, but all net income is subject to self-employment tax. An S Corp election allows you to split income between salary and distributions, reducing that tax burden significantly once profits consistently exceed $50,000 per year. Oregon-specific factors like state income tax rates up to 9.9%, the Corporate Activity Tax, and the Pass-Through Entity Elective Tax add layers that make this a genuinely state-specific planning question. This breakdown covers the real cost comparison, formation fees, payroll requirements, and the step-by-step process for deciding which structure fits your situation in 2026.
