(2)(a) In the case of a notice of assessment pursuant to any law administered by the department, if the deficiency is not paid within 60 days after the date of the notice of assessment, the interest rate provided under ORS 305.220 shall be four percent greater than the annual interest rate provided under ORS 305.220, but only for interest periods that begin 61 days after the date of notice of assessment.
