"State tax expenditure" means those revenue losses attributable to provisions of State tax law which establish special tax treatment, including but not limited to tax law definition, deduction, exclusion, exemption, deferral, credit, preferential tax rate or other special tax provision resulting in a reduced tax liability for certain persons, individuals, types of income, transactions or property from the liability which would be presumed to exist without the State tax expenditure.
