Annual CPPR filing
The Multnomah CPPR is a confidential personal property return for business furniture, fixtures, equipment, floating property, leased or rented property, and related schedules. The 2026 form shows a March 15, 2026 filing deadline.
RMV review required
Several schedules ask for the owner's opinion of real market value while assessor RMV fields are left blank. Business Property Desk only carries user-supplied or user-confirmed owner RMV into the packet; it does not calculate an official Oregon DOR valuation factor or certified value.
Late penalties and audit risk
The CPPR instructions describe late penalties of 5%, 25%, and 50% of tax owed depending on lateness. The form also states that the return is subject to audit, so source records should be retained.
Common questions
Does Business Property Desk calculate Multnomah RMV?
No. The Multnomah lane only carries user-supplied or user-confirmed owner RMV into the packet. It is not an Oregon valuation engine.
What Multnomah cases are supported?
Only simple renewal-style cases with an existing account, one location or tax code area, ordinary owned assets, and user-supplied RMV.
What is outside the Multnomah MVP?
Stop for first-time uncertainty, sale, closure, move, industrial return, leasing company, floating property, professional library, vehicle-only cases, or unclear owner RMV.
Can the return be audited?
The CPPR form states that the return is subject to audit, so source records should be kept with the packet.
