Common Deductions for Oregon Freelancers

Oregon freelancers should maximize deductions given the state's high progressive rates (up to 9.9%). **Home office expenses**: Claim dedicated business space using simplified ($5/sq ft) or actual expense method—especially valuable in high-cost Portland. **Business mileage**: 67 cents/mile for 2025; important for those serving clients across the Portland metro or statewide. **Equipment and software**: Computers, cameras, tools, and business software are deductible—particularly valuable for Oregon's large tech freelancer community. **Professional development**: Courses, certifications, and educational materials related to your business qualify. **Health insurance premiums**: Self-employed individuals can deduct 100% of health insurance costs. **Retirement contributions**: SEP-IRAs and Solo 401(k)s reduce both federal and Oregon taxable income—saving you at your federal rate plus up to 9.9%. **Marketing expenses**: Website costs, business cards, and promotional materials are deductible. Oregon uses federal taxable income as its starting point, so all Schedule C deductions automatically reduce OR taxes. Given Oregon's high rates, maximizing deductions is especially valuable—every dollar deducted could save you nearly 10% in state taxes alone.
