Internal Audit

Construction Excise Tax (CET) Distribution

In accordance with Oregon Revised Statutes (ORS) 320, since May 2007, the State of Oregon has allowed school districts to impose a construction excise tax (CET) on projects that result in a new structure or additional square footage to an existing structure.  The Clackamas County Department of Transportation and Development, Building Codes Division, administers this tax for some cities and the unincorporated areas in the participating districts in the County.  The funds are distributed by the Treasurer’s Office in accordance with the calculations provided to us by the Building Codes Division.  

Questions regarding the calculation or amount distributed should be directed to the Building Codes Division at 503-742-4750.


Tax Distribution

In an effort to become more efficient and effective, the Treasurer’s Office is posting tax distribution statements and the associated recap of transactions statements online. We have also developed an email list to email out notifications of when these statements are available online. In compliance with ORS 311.395 tax distributions are performed on the 10th business day of every month, except in November when distributions are performed more frequently.

If you have any questions, please do not hesitate to contact the Treasurer’s Office.
