When Do I Need to file an Oregon State Tax Amendment?
If you are expecting a refund, you have up to 3 years since the due date of the original return or the date you actually filed the original tax return, whichever is later, to file a tax amendment form to claim that refund.
If it has already been 3 years since those deadlines passed, then you still may file a tax amendment and get a refund if it has been less than 2 years since you paid the tax, or if you had a net operating loss carry back, or the IRS made changes to your federal tax return.
In case of a net operating loss carry back you have 3 years to file an amendment since the year when the loss occurred. In case of an IRS correction, you have 2 years to file an amendment since the date of the correction.
