Example 1: In each of years 2015, 2016, and 2017, farmer Joe had taxable income of $15,000. In 2018, Joe had taxable income of $30,000 (prior to any farm income averaging election) and electable farm income of $9,000. Joe makes a farm income averaging election to average all $9,000 of his electable farm income for 2018. Thus, $3,000 of elected farm income is allocated to each of the tax years 2015, 2016, and 2017. Joe's 2018 tax liability is the sum of: (a) The Oregon tax on $21,000 (2018 taxable income minus elected farm income); plus(b) For each of the tax years 2015, 2016, and 2017, the Oregon tax on $18,000 minus the Oregon tax on $15,000 (the increase in tax attributable to the elected farm income allocated to each year). In 2019, Joe has taxable income of $50,000 and electable farm income of $12,000. Joe makes a farm income averaging election to allocate all $12,000 of his electable farm income for 2019. Thus, $4,000 of elected farm income is allocated to each of the tax years 2016, 2017, and 2018. Joe's 2019 tax liability is the sum of:
(a) The Oregon tax on $38,000 (2019 taxable income minus elected farm income); plus(b) For both 2016 and 2017, the Oregon tax on $22,000 ($15,000 + $3,000 + $4,000) minus the tax on $18,000 (the increase in Oregon tax attributable to the elected farm income allocated to these years after increasing each years' taxable income by elected farm income allocated to each year by the 2018 farm income averaging election); plus(c) For tax year 2018, the Oregon tax on $25,000 (the 2018 taxable income minus elected farm income plus the $4,000 allocated to this base year) minus the Oregon tax on $21,000 (the increase in tax attributable to the elected farm income allocated to this year after reducing this year's taxable income by the 2018 elected farm income).
