Example:
A taxpayer determines that its New York State franchise tax for taxable year 1990 is $15,000 before any credits are allowed. The taxpayer has a credit for the special additional mortgage recording tax of $8,000, an eligible business facility credit of $6,000, a credit for servicing mortgages of $10,000, an economic development zone capital corporation tax credit of $1,000 and an economic development zone tax credit of $2,000. The taxpayer is first allowed the eligible business facility credit of $6,000. Secondly, the economic development zone capital corporation tax credit of $1,000 is allowed. Thirdly, a credit for servicing mortgages of $8,000 is allowed because this credit may reduce the tax to zero. The unused portion of this credit may not be carried forward. The taxpayer is allowed to carry forward to the succeeding taxable year or years an economic development zone wage tax credit of $2,000 and a credit for the special additional mortgage recording tax of $8,000.
