Assessment Date

ORS 308.250
(1) All personal property not exempt from ad valorem taxation or subject to special assessment shall be valued at 100 percent of its real market value, as of January 1, at 1:00 a.m. and shall be assessed at its assessed value determined as provided in ORS 308.146 (Determination of maximum assessed value and assessed value).
The assessment date of January 1st looks to seek and capture all additions and disposals made in the prior year, so you can think of personal property as always being one year behind. Example:
  • In 2019, your business purchased items and disposed of items.
  • January 1st, 2020 is the assessment date and you fill out your return using that date as the guide. You do not report purchases made after January 1st, nor do you report disposals made after January 1st. So, as of January 1st, what assets did your business own or what personal items were being used for business purposes?
  • If a bill will be generated, it will not be ready until the following October and will be mailed out by the 25th. (October 2020)
  • When you pay the bill, you are paying what was reflected in your business as of January 1st, 2020.

  • The tax year can complicate things since we have a split year tax year. When you pay your bill, you are paying for July 1st, 2020 to June 30th, 2021 BUT REMEMBER you are paying for what was reflected as of January 1st, 2020! This can be confusing for businesses who sold to another entity as they may be unsure who is responsible for the tax, but this is a private matter between the two parties.
