What this figure does not include

  • Utah's taxpayer tax credit is modelled in full: 6% of the federal standard deduction plus 6% of the Utah personal exemption per dependent, reduced by 1.3% of Utah taxable income above the base amount.
  • The credit is computed from the federal *standard* deduction. A filer who itemizes federally gets a different credit, and Utah also subtracts state income tax deducted federally from the base; neither is modelled.
  • The phase-out is applied against income as we measure it. Utah applies it to Utah taxable income after state additions and subtractions, which we do not model.
  • The qualified-exempt-taxpayer rule (no Utah tax when federal AGI is at or below the federal standard deduction) is not modelled.
  • Utah's retirement credit, earned income tax credit and social security benefits credit are not modelled.
