  2. Oregon Department of Revenue Business Tax Registration

    Oregon has no general sales tax and no general Department of Revenue business registration — most businesses simply file Oregon income/excise tax returns. Register with DOR only for specific tax programs: payroll withholding (Business Identification Number) if you hire employees; the Corporate Activity Tax, which requires registration within 30 days once Oregon commercial activity exceeds $750,000 in a year (tax applies above $1 million); and, for self-employed individuals working in the Portland-area TriMet district (or Eugene-area Lane Transit District), the transit self-employment tax filed with DOR.
