The proper calculation of the credit for taxes paid to other states or countries for 2002 tax year includes a pro-rata application of Arizona exemptions and deductions to the income from the other state or country. Where the laws of another state provide for a credit for taxes paid to Arizona but a taxpayer is unable to take the credit because of electing to file on a composite return in that state, the taxpayer is not eligible in Arizona to take a credit for taxes paid to that state.
