Commonly Used Formulas

Income Tax (Simplified):
Taxable Income = Income - Standard Deduction - (Exemptions × Exemption Amount)
Tax = Σ (Portion in Bracket × Rate) − Credits
Property Tax:
Taxable Value = Assessed Value − Applicable Exemptions
Property Tax = (Taxable Value ÷ 1,000) × Tax Rate
General Excise Tax (GET):
Total GET = Gross Income × (Base Rate + Surcharge Rate)
Vehicle Tax:
Total Fees = Registration Fee + (Vehicle Weight × Rate) + Additional Fees

Frequently Asked Questions (FAQ)

Is this calculator accurate for filing taxes?

The calculator covers major state and county taxes: income, property, general excise, and vehicle taxes. It does not include transient accommodation taxes or alcohol/tobacco taxes.
