Overview

Oregon enacted a new corporate activity tax (CAT) on May 16 that is imposed in addition to its corporation income and excise taxes. Since enactment, the CAT was subject to a citizen petition referendum and a technical correction bill. With the referendum formally withdrawn, the CAT became effective on September 29, 2019. According to the Oregon Department of Revenue, the new tax is imposed on a calendar-year basis beginning January 1, 2020, regardless of the taxpayer’s income tax filing year.

The takeaway

H.B. 2164 provides several technical corrections to the Oregon CAT. According to the Department, the new tax begins January 1, 2020. Estimated tax payments are payable to the Oregon Department of Revenue on or before the last day of January, April, July, and October of each year for the previous calendar quarter. Oregon requires that taxpayers pay at least 80 percent of the balance due for any quarter or the Department may impose a penalty.
