Does Oregon follow federal treatment of LLCs considered "disregarded entities"? Yes.

• We are starting a nonprofit organization; what do we file with you? You do not need to file "articles of incorporation" or other forms with the Department of Revenue. If you only file a federal Form 990 with the IRS, you do not need to file a return with Oregon. If you file a federal Form 990-T (unrelated business income), you must file an Oregon Form 20. • How many years can we carry back or carry forward a net operating loss (NOL)? Oregon allows corporate NOLs to be carried forward for up to 15 years. THERE IS NO NET OPERATING LOSS CARRYBACK ALLOWED, however there is a capital loss carryback provision. • What is the interest rate for refunds and deficiencies? If you do not pay the tax by the due date, interest will be charged on the unpaid tax. Interest periods generally begin on the 16th day of the month the return is due. Returns are due on the 15th unless the 15th falls on a Saturday, Sunday or holiday. Interest is figured daily for periods of less than a month.  more
