OAR 150-316-0491: Estimated Tax: Partnership and S Corporation Income of Part-year Residents and Nonresidents

For purposes of imposing interest on underpayment of estimated tax, an exception exists for part-year and nonresidents receiving income from an S corporation. No interest will be imposed on the underpayment attributable to the shareholders pro rata share of the S corporation income if the income is for the initial year in which S corporation status is elected and the shareholder is a nonresident or for the prior tax year was a part-year resident for Oregon. This exception applies to tax years beginning on or after January 1, 1987. Example: Frank and Ethel move to Oregon in August, 2006. Frank is a partner in an Oregon partnership. The partnership incorporates in 2007 and elects S corporation status. For 2007, Frank and Ethel file as full-year Oregon residents and report their share of the S corporation income. No interest is imposed on any underpayment attributable to Frank's share of the S corporation income because they meet the exception. They are part-year residents for 2006; 2007 is the initial year of election of S corporation status.
