(4) The credit for tax paid to another state under section 235-55, HRS, shall be allowed only for tax paid on out-of-state income allocable to the period of residence. Example: T, an unmarried cash basis calendar year taxpayer, was a resident of Arizona on January 1, 1993. T moved to Hawaii on April 1, 1993, and continued to work as an insurance agent. T is a Hawaii resident for the remainder of 1993. T received $20,000 as gain from the sale on March 20, 1993, of Arizona real property held for investment. T earned commissions of $25,000 for policies sold after April 1, 1993. T earned initial and renewal commissions of $12,000 for policies sold before that date, $4,000 of which T earned before April 1, 1993. In addition, T had signed a business consulting contract with one Arizona client, for which T was paid an additional $1,200 for services rendered throughout the year. T's Hawaii income is computed as follows:
(1) The $20,000 gain is out-of-state income earned when T was a nonresident. None of it is attributable to Hawaii.(2) The commissions of $25,000 are from a trade or business carried on in Hawaii, and are Hawaii source income. The commissions were earned when T was a Hawaii resident. All of these commissions are attributable to Hawaii.(3) The $12,000 in commissions earned before April 1993 is from a trade or business carried on in Arizona, and is thus out-of-state income. However, only $4,000 was earned when T was a nonresident. The remaining $8,000 is attributable to Hawaii.(4) It cannot be determined whether the remaining $1,200 in commission income was generated while T was a Hawaii resident. Thus, because T was a resident for nine months in 1993, 9/12 x $1,200, or $900, shall be attributable to Hawaii unless T demonstrates otherwise to the satisfaction of the department.
