If in the opinion of the Director the method employed in N.J.A.C. 18:7-5.6 does not properly reflect the taxpayer's net income properly apportionable to New Jersey under the Act for the period covered by its New Jersey return, the Director may determine entire net income solely on the basis of the taxpayer's income during such period.
N.J. Admin. Code § 18:7-5.7
