Notes of Decisions

The goal of this chapter is to incorporate all of the pro­vi­sions of the federal Internal Revenue Code; taxable income should be adjusted whenever the result of the adjust­ment is to give effect to the policies or principles of the federal Internal Revenue Code, even though no express authority for the adjust­ment is present in the statutes. Christian v. Dept. of Rev., 269 Or 469, 526 P2d 538 (1974); Smith v. Dept. of Rev., 270 Or 456, 528 P2d 73 (1974)
