Oregon edges closer to âkickerâ refund. The latest forecast of Oregon tax revenue is increasing speculation taxpayers could see a kicker refund. If Democratic Gov. John Kitzhaber is re-elected, he will base his budget on the Nov. 13 forecast.
Corporation estimated tax. Oregonâs estimated tax laws are not the same as federal estimated tax laws. You must make quarterly estimated tax payments if you expect to owe tax of $500 or more with your return. If you don't make estimated payments as required, you may be subject to interest on underpayment of estimated tax (UND).
