New Oregon Corporate Activity Tax Mirrors Ohio and Washington Tax

Oregon’s new Corporate Activity Tax (CAT) requires qualifying businesses to register and pay tax for operating in Oregon, which mirrors similar taxes in Ohio and Washington. In Oregon, a business qualifies by exceeding $750,000 in gross receipts within state lines. After meeting the threshold, businesses must register with the Oregon Department of Revenue. Ohio and Washington have a similar tax, Ohio’s Commercial Activity Tax (CAT), and Washington’s Business and Occupation Tax (B&O).

Oregon Corporate Activity Tax

The Oregon Corporate Activity tax is a gross receipts tax for the privilege of doing business in the state. The tax is in addition to any current state taxes. The CAT is not an income tax or sales tax (also called a transaction tax), and tax is due even when there is a business loss.

A business must register with the Department of Revenue within 30 days after gross receipts exceed $750,000 within state lines. Businesses that fail to register within 30 days are subject to penalties. The first $1 million in gross receipts is exempt from tax for a fee of $250. Businesses with gross receipts between $750,000 and $1 million only pay the $250 fee. Gross receipts over $1 million are taxed at 0.57% and require the business to file an annual return by April 15th. Oregon allows a 35% subtraction for certain labor and other costs apportioned by Oregon. Click here to see example calculations and how to calculate your CAT liability:

Quarterly estimated tax payments can be made throughout the year on 4/30, 7/31, 10/31, and 1/31 for the preceding quarter. A business estimating to owe more than $5,000 in CAT for the year is required to pay estimated payments.
