Interest on certain installment sales.
Do you have installment sales that required you to pay interest on the deferred tax liability for federal purposes? If so, you must also compute interest for Oregon. The amount due for Oregon is computed the same as the federal amount. The interest rate for 2018 was 5 percent.
The interest rate for 2019 and 2020 is 6 percent per year, or 0.5 percent (0.005) per month.
