Corporate Income Tax—Single Sales Factor

The tax rate on corporate income of firms doing business in the state is the greater of a minimum tax based on relative sales ($150-$100,000, approximately 0.1%) or an income-based levy of 6.6% on amounts up to $250,000 and 7.9% above that (this second tier switches to $10 million in 2013).

Oregon businesses are taxed on a portion of their total income derived from sales within the state of Oregon. This corporate income tax is considered “Singe Sales Factor” tax, as it only considers Oregon sales in determining corporate income taxes owed to the state. Other states often include additional assets and payroll, making them “multi-factor” taxes.

This aspect of the corporate income tax has a tremendous impact for multi-state companies based in Oregon. If a company is headquartered in Oregon but sells products throughout the country, or world, that company only pays Oregon corporate income tax based on the amount of income coming from sales within state lines.

Property Tax

The present property tax system in Oregon has been largely shaped by Measure 5 passed in 1990 and Measure 50 passed in 1997.

Measure 5 mandates limits on the taxes imposed on real property.  The tax limits of $5.00 per $1,000 real market value for school taxes and a limit of $10.00 per $1,000 real market value for general government operating taxes means for property in Oregon the assessment cannot exceed $15.000 per $1,000 real market value for any real property.  If either the school tax rate or the general government operating rate exceeds its maximum as set in law, each corresponding tax district will have its tax rate reduced proportionally until the $15.000 per $1,000 limit is achieved.  This is called compression.

Measure 50, passed in 1997 further adjusted the property tax system by (1) switching to permanent rates; (2) reducing the value of property that is assessed the tax; and (3) limiting annual growth in the assessed value of a property.  The assessed value is now set at no more than 90 percent (90%) of the real market value of the property.  The assessed value cannot be increased by more than three percent (3%) annually.

These limitations do not include voter approved bond issuances.
