What we do
We are responsible for the annual assessments of certain transportation, communication, and energy properties for property tax purposes.
These annual assessments are sent to the county assessors and tax collectors for the billing, collection, and ultimately the distribution of property tax dollars.
Each company is required to file a signed annual statement to us. The following companies must file on or before
March 15 of each year:
- Class A electric.
- Large water transportation.
- Air transportation.
- Private railcar.
The following companies must file on or before
February 1 of each year:
- Small water transportation.
- Toll bridge.
- Small electrics.
Mutual and cooperative electric distribution systems must file on or before
March 1 of each year (ORS 308.805, 308.810).
To ask for an extension, send us a written request that includes:
- Reason for the filing extension.
- A contact name, telephone number, and email address.
Your request must be postmarked or received by the due date of the return.
Once your request is received, we'll notify your contact person by mail with our decision to either grant or deny the request.
