Oregon Payroll Tax and Registration Guide

Use this checklist to make sure you’ve covered everything required to set up your account as an Oregon employer so OnPay can accurately file and pay taxes on your behalf: 

OnPay handles the filing of all state and local taxes for businesses in Oregon, including:

If you are an existing employer who has previously run payroll in the state of Oregon, you likely already have the IDs and online accounts needed for OnPay to process your tax filings. 

If you are a new employer in Oregon, you will need to register your business with the Oregon Department of Revenue and Oregon Department of Labor. This must be completed for OnPay to be able to file and pay your Oregon taxes.

Business Identification Number (BIN)

Existing Oregon Employer: 

You can find your Business Identification Number on notices received from the Oregon Department of Revenue. If you cannot locate this document or your BIN, please call the Oregon Department of Revenue at (800) 356-4222 to request it.

New Oregon Employer: Register with the Oregon Department of Revenue 

• You can check if you are liable yet and register online with the Central Business Registry. 
• You should receive your BIN in 3-5 days after registering online. You will also receive your unemployment tax rate once you've registered with the Central Business Registry.

Unemployment ID and Tax Rate

Existing Oregon Employer: 

• In Oregon, your BIN serves as your Unemployment ID for the Oregon Employment Department. 
• Your Overall Tax Rate appears on the top right of the Notice of Tax Rate you would have received from the Employment Department. It generally ranges from 0.9% to 5.4% with a wage base of $47,700.

New Oregon Employer: Register with the Oregon Employment Department

• Go to the OED website to register your business.
• Once you are registered, you will receive your Business Identification Number (BIN).
• The new employer rate is 2.4%, with a wage base of $47,700.

OnPay works with government entities on your behalf, reporting new hires to state labor departments, calculating tax liabilities, and filing financial reports. To do this effectively, you will need to add OnPay as your authorized representative.
