Oregon Additions

Oregon Additions to Taxable Income

Oregon requires taxpayers to include certain additions to their taxable income when filing their state income tax return. These additions ensure that income that may not be fully captured on federal returns is properly accounted for in Oregon’s tax system.

What Are Oregon Additions?

According to Oregon Department of Revenue (DOR) guidelines, additions are adjustments made to your federal taxable income to determine your Oregon taxable income. These additions are required for specific types of income or transactions that are taxed differently at the state level.

Key Additions to Consider

• Capital Gains and Losses: Oregon taxes capital gains received during the year. Full-year residents must include capital gains from Oregon sources. Net capital losses are limited to $3,000 per year ($1,500 if married filing separately). (Source: Publication OR-17, Page 48)
• Modifications for Nonresidents and Part-Year Residents: Nonresidents and part-year residents must add modifications for each period they were in Oregon. This includes capital gains or losses from Oregon sources during their residency period. (Source: Form OR-40-NP, Page 15)
• Other Additions: Additional items that may need to be added to Oregon taxable income are detailed in the “Additions” section of Publication OR-17. These may include certain types of income not fully reported on federal forms.

How to Report Additions

Taxpayers should use the appropriate forms and worksheets provided by the Oregon Department of Revenue. For example, capital gains may require using Worksheet FCG from Publication OR-FCG to compute the tax. The worksheet is not submitted with the return but should be kept for records.

When completing Form OR-40, taxpayers must ensure all pages of any attached schedules (such as Schedule OR-DONATE or Schedule OR-WFHDC) are included and marked with the correct 2025 form designation.
