KRA Duty Methodology

Duty Check uses the correct KRA formula:

CRSP Value (from official list)
  × depreciation factor            ← based on vehicle age
  = Customs Value (CV)

Import Duty     = CV × 25%
Excise Duty     = (CV + Import Duty) × 20%
VAT             = (CV + Import Duty + Excise Duty) × 16%
IDF             = CV × 2.25%  (min KES 5,000)
RDL             = CV × 1.5%
