2. Application Fees & 2-Year Cost Comparison

Enter a tax amount above to see the application fees and cost comparison.
Important notes:
• Official application fee is $0 if filed on time. Late fee is set by the state (10% of taxes, $20 min – $180 max for 2026).
• My professional service fee is $350 every two years to prepare and file the documents for you.
• Deferred taxes still accrue 6% simple interest per year and must eventually be repaid (usually when the home is sold or the owner dies).
3. Requirements Checklist (2026)
Check each item you believe you meet. All must generally be true as of April 15 of the application year. Final approval is made by the Oregon Department of Revenue.
