(3) For contributions made to an IRA account under section 219 of the Internal Revenue Code, the deduction for Oregon is equal to the federal deduction times the ratio of Oregon compensation over compensation from all sources. In general, "compensation" includes alimony, wages, professional fees, or other amounts derived from or received from personal services rendered and included in gross income for the tax year. It does not include pensions, annuities, or other forms of deferred compensation. Example: Assume a nonresident taxpayer had a $2,000 IRA deduction for federal purposes. His federal and Oregon wages were $40,000 and $20,000, respectively. His Oregon deduction would be equal to $1,000 or ($2,000 x (20,000/40,000)).
