Hello there, @Mjasphalt.
Let me provide some information about the Oregon WBF in QuickBooks Online.
QuickBooks Online (QBO) will automatically assign a particular rate (the State of Oregon provided the fixed-rate) it depends on the compliance of the ER and EE. QuickBooks Online will be notified in case the state of Oregon changes the tax rate and users will be informed you
via email.
For more information about the tax compliance in Oregon: Oregon Payroll Tax Compliance. It covers the local tax name which QBO supported.
Please keep in touch if you need anything else. Have a good day!
