Calculation Formulas

Untaxed → Taxed Amount

Taxed Amount = Untaxed Amount + (Untaxed Amount - Exemption) × Tax Rate

Taxed Amount → Untaxed Amount

Untaxed Amount = (Taxed Amount + Exemption × Tax Rate) ÷ (1 + Tax Rate)

Taxed Amount & Untaxed Amount → Tax Rate

Tax Rate = (Taxed Amount - Untaxed Amount) ÷ (Untaxed Amount - Exemption)

Tax Amount & Tax Rate → Taxed Amount & Untaxed Amount

Untaxed Amount = Tax Amount ÷ Tax Rate + Exemption; Taxed Amount = Untaxed Amount + Tax Amount
