Key Formulas Used

Income Tax:
Taxable Income = Gross Income − Standard Deduction − (Dependents × $1,000)
Tax = Bracketed Rates Applied to Taxable Income
Final Tax = Calculated Tax − Tax Credits (if applicable)

Property Tax:
Assessed Value = Market Value × Assessment Ratio
Taxable Value = Assessed Value − Applicable Exemptions
Property Tax = Taxable Value × (Millage Rate ÷ 1,000)

Sales Tax:
Sales Tax = Purchase Amount × (State + County + City Tax Rates)
Total = Purchase Amount + Sales Tax

Vehicle Registration:
Excise Tax = Original MSRP × Excise Rate (based on age)
Total = Registration Fee + Excise Tax + Additional Fees (e.g., EV or Custom Plate)
